具体实施方式DETAILED DESCRIPTION
如图1-图5所示，本发明提供一种多功能车，包括：连接座1、支撑模块2和座椅模块3，座椅模块3可拆卸的安装在支撑模块2上；支撑模块2包括前支撑杆21、后支撑杆22和两个侧支撑杆23，前支撑杆21、后支撑杆22和两个侧支撑杆23的下端部分别设置有支撑轮4；连接座1的一侧面设置有第一连接轴11，连接座1的另一侧面设置有第二连接轴12，连接座1的前后端面分别设置有第三连接轴13；前支撑杆21铰接在第一连接轴11上，后支撑杆22铰接在第二连接轴12上，侧支撑杆23铰接在对应的第三连接轴13上；其中，所述多功能车展开后，前支撑杆21、一侧支撑杆23、后支撑杆22和另一侧支撑杆23依次搭接在一起。As shown in Figures 1 to 5, the present invention provides a multi-functional vehicle, comprising: a connecting seat 1, a support module 2 and a seat module 3, the seat module 3 is detachably mounted on the support module 2; the support module 2 comprises a front support rod 21, a rear support rod 22 and two side support rods 23, the lower ends of the front support rod 21, the rear support rod 22 and the two side support rods 23 are respectively provided with support wheels 4; a first connecting shaft 11 is provided on one side of the connecting seat 1, a second connecting shaft 12 is provided on the other side of the connecting seat 1, and a third connecting shaft 13 is respectively provided on the front and rear end surfaces of the connecting seat 1; the front support rod 21 is hinged on the first connecting shaft 11, the rear support rod 22 is hinged on the second connecting shaft 12, and the side support rod 23 is hinged on the corresponding third connecting shaft 13; wherein, after the multi-functional vehicle is unfolded, the front support rod 21, one side support rod 23, the rear support rod 22 and the other side support rod 23 are overlapped together in sequence.
具体而言，本实施例中的多功能车采用支撑模块2作为支撑骨架来安装座椅模块3，而支撑模块2采用四根支撑杆来实现支撑。四根支撑杆则通过对应的连接轴安装在连接座1上。在实际使用过程中，当打开多功能车后，前支撑杆21、一侧支撑杆23、后支撑杆22和另一侧支撑杆23转动展开并依次抵靠在一起形成类似井字形的结构，四根支撑杆相互支撑且相互限制，进而形成以稳定的支撑结构来放置座椅模块3。而当需要折叠多功能车时，则仅需要转动四根支撑杆即可完成折叠的操作。Specifically, the multi-function vehicle in this embodiment uses the support module 2 as a support frame to install the seat module 3, and the support module 2 uses four support rods to achieve support. The four support rods are installed on the connecting seat 1 through corresponding connecting shafts. In actual use, when the multi-function vehicle is opened, the front support rod 21, the one side support rod 23, the rear support rod 22 and the other side support rod 23 are rotated and unfolded and abutted against each other in sequence to form a structure similar to a tic-tac-toe shape. The four support rods support and restrict each other, thereby forming a stable support structure to place the seat module 3. When the multi-function vehicle needs to be folded, it is only necessary to rotate the four support rods to complete the folding operation.
为了在展开状态下，确保整体姿态保持稳定的状态，则多功能车还包括锁紧绳5，锁紧绳5用于在所述多功能车展开后连接在前支撑杆21和后支撑杆22之间。具体的，在多功能车展开后，则通过锁紧绳5在后方将前支撑杆21和后支撑杆22连接在一起，以通过锁紧绳5起到锁紧限位的作用。In order to ensure that the overall posture remains stable in the unfolded state, the multi-purpose vehicle further includes a locking rope 5, which is used to be connected between the front support rod 21 and the rear support rod 22 after the multi-purpose vehicle is unfolded. Specifically, after the multi-purpose vehicle is unfolded, the front support rod 21 and the rear support rod 22 are connected together at the rear through the locking rope 5, so that the locking rope 5 plays a role of locking and limiting.
多功能车自身具有四个铰接部位，因此整体结构简单，且可以有效的提高使用可靠性，并方便用户操作使用。The multi-purpose vehicle itself has four hinged parts, so the overall structure is simple, and can effectively improve the reliability of use and facilitate user operation.
另外，座椅模块3则采用可拆卸的方式安装在支撑模块2上，因此，可以根据用户的需要在支撑模块2上配置不同结构功能的座椅模块3。以下结合附图举例说明。In addition, the seat module 3 is detachably mounted on the support module 2, so that the seat module 3 with different structural functions can be configured on the support module 2 according to the needs of the user. The following is an example with reference to the accompanying drawings.
例如：如图1所示，作为婴儿推车，座椅模块3包括座兜31和支撑绳32，座兜31通过支撑绳32悬挂在支撑模块2上，座兜31位于前支撑杆21、后支撑杆22和两个侧支撑杆23之间。具体的，座兜31通过支撑绳32悬挂安装在四个支撑杆上，座兜31将位于连接座1的上方，使得婴儿能够坐在座兜31中，而婴儿的双腿则可以叉在前支撑杆21的两侧。而对于支撑绳32的连接方式，则可以采用穿绳的方式，即座兜31的上边缘形成用于穿设支撑绳32的通道，相对应的，四个支撑杆的上端部设置有通孔来穿设支撑绳32。另外，为了在座兜31的底部进行位置固定，则座椅模块3还包括拉绳33，拉绳33连接在前支撑杆21和/或后支撑杆22上，座兜31的下部与拉绳33连接。拉绳33能够在座兜31的底部进行紧固，以提高座兜31的安装稳定性。另外，根据需要，拉绳33还连接在两个侧支撑杆23上。而有关拉绳33的安装方式，则可以采用支撑绳32的穿绳方式，在此不做赘述。For example, as shown in FIG1 , as a baby stroller, the seat module 3 includes a seat pocket 31 and a support rope 32. The seat pocket 31 is suspended on the support module 2 through the support rope 32, and the seat pocket 31 is located between the front support rod 21, the rear support rod 22 and the two side support rods 23. Specifically, the seat pocket 31 is suspended on the four support rods through the support rope 32, and the seat pocket 31 will be located above the connecting seat 1, so that the baby can sit in the seat pocket 31, and the baby's legs can be forked on both sides of the front support rod 21. As for the connection method of the support rope 32, a threading method can be adopted, that is, the upper edge of the seat pocket 31 forms a channel for threading the support rope 32, and correspondingly, the upper ends of the four support rods are provided with through holes for threading the support rope 32. In addition, in order to fix the position at the bottom of the seat pocket 31, the seat module 3 also includes a drawstring 33, which is connected to the front support rod 21 and/or the rear support rod 22, and the lower part of the seat pocket 31 is connected to the drawstring 33. The pull rope 33 can be fastened at the bottom of the seat 31 to improve the installation stability of the seat 31. In addition, as required, the pull rope 33 is also connected to the two side support rods 23. As for the installation method of the pull rope 33, the threading method of the support rope 32 can be adopted, which will not be described in detail here.
例如：如图2所示，儿童骑行车，则座椅模块3包括车座34，车座34可拆装的安装在后支撑杆22的下部。具体的，儿童坐在车座上，可以手扶两侧的侧支撑杆23进行滑动，也可以通过家长手扶前支撑杆21的上端来推行。For example, as shown in FIG2 , for a child riding a bicycle, the seat module 3 includes a seat 34, which is detachably mounted on the lower portion of the rear support rod 22. Specifically, when a child sits on the seat, he or she can slide by holding the side support rods 23 on both sides, or the parent can push the bicycle by holding the upper end of the front support rod 21.
进一步的，为了方便的将展开后的四个支撑杆进行定位，则前支撑杆21设置有第一限位柱211，后支撑杆22设置有第二限位柱221，侧支撑杆23设置有第三限位柱231；其中，所述多功能车展开后，前支撑杆21抵靠在其中一第三限位柱231上，后支撑杆22抵靠在另一第三限位柱231上，其中一侧支撑杆23抵靠在第一限位柱211上，另一侧支撑杆23抵靠在第二限位柱221上。具体的，四个支撑杆的中部分别设置有限位柱，限位柱以基本垂直于支撑杆的方式向一侧延伸，这样，在四根支撑杆转动打开后，则可以通过限位柱来有效的支撑相对应的支撑杆，以提高稳定性。Further, in order to conveniently position the four support rods after being unfolded, the front support rod 21 is provided with a first limiting column 211, the rear support rod 22 is provided with a second limiting column 221, and the side support rod 23 is provided with a third limiting column 231; wherein, after the multifunctional vehicle is unfolded, the front support rod 21 abuts against one of the third limiting columns 231, the rear support rod 22 abuts against another third limiting column 231, wherein one side support rod 23 abuts against the first limiting column 211, and the other side support rod 23 abuts against the second limiting column 221. Specifically, limiting columns are respectively provided at the middle of the four support rods, and the limiting columns extend to one side in a manner substantially perpendicular to the support rods, so that after the four support rods are rotated and opened, the corresponding support rods can be effectively supported by the limiting columns to improve stability.
另外，对于四根支撑杆的结构，则可以采用直杆的方式，即如图6所示的结构形式，进而方便组装并降低制造成本。而为了提高多功能车的推行平稳可靠性，如图7所示，前支撑杆21、后支撑杆22和两个侧支撑杆23均为弯折管；其中，所述多功能车展开后，前支撑杆21的下端部与后支撑杆22的下端部所在的直线、垂直于两个侧支撑杆23的下端部所在的直线。这样，便可以使得前后方向的两个支撑轮4能够沿同一直线直行，且两侧的两个支撑轮4将对称布置，以提高用户使用体验性。In addition, for the structure of the four support rods, a straight rod method can be adopted, that is, the structural form shown in Figure 6, which is convenient for assembly and reduces manufacturing costs. In order to improve the smoothness and reliability of the multi-functional vehicle, as shown in Figure 7, the front support rod 21, the rear support rod 22 and the two side support rods 23 are all bent tubes; wherein, after the multi-functional vehicle is unfolded, the straight line where the lower end of the front support rod 21 and the lower end of the rear support rod 22 are located is perpendicular to the straight line where the lower ends of the two side support rods 23 are located. In this way, the two support wheels 4 in the front and rear directions can move straight along the same straight line, and the two support wheels 4 on both sides will be symmetrically arranged to improve the user experience.
本发明的技术方案相对现有技术具有如下技术效果：通过在连接座上配置多根连接轴，进而通过不同的连接轴来安装各个支撑杆，这样，在折叠或展开的过程中，仅需要驱动支撑杆相对于连接座转动即可，整个结构简单且方便操作，使用可靠性较高；另外，对于座椅模块则采用可拆卸的方式安装在支撑模块上，进而可以根据需要拆装不同的座椅模块形式来满足功能多样化的设计要求。The technical solution of the present invention has the following technical effects compared with the prior art: by configuring multiple connecting shafts on the connecting seat, and then installing each support rod through different connecting shafts, in this way, during the folding or unfolding process, it is only necessary to drive the support rod to rotate relative to the connecting seat, and the entire structure is simple and easy to operate, with high reliability; in addition, the seat module is installed on the support module in a detachable manner, and different seat module forms can be disassembled and assembled as needed to meet the design requirements of diversified functions.
以上仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
