[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0053] As people's living standards improve, there are more and more types of vehicles, such as carts or seats, etc. Currently, many vehicles do not have a shock-absorbing function, or most vehicles with a shock-absorbing function have poor shock-absorbing function.

[0054] In order to solve this technical problem, the present invention provides a carrier.

[0055] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 The vehicle includes a chassis assembly 100, a frame assembly 200 and a support assembly 300; the frame assembly 200 is located above the chassis assembly 100, and the support assembly 300 includes a plurality of elastic members arranged on the chassis assembly 100, the elastic members are engaged with the frame assembly 200, and the plurality of elastic members are connected between the frame assembly 200 and the chassis assembly 100 to suspend the frame assembly 200 on the chassis assembly 100.

[0056] The vehicle in the present invention can be a cart or a chair, for example. The chassis assembly 100 is the component that supports the entire vehicle. The chassis assembly 100 may include a base frame and rollers 130 mounted on the base frame. The base frame may be triangular, quadrilateral, or other shaped. Three, four, or other rollers 130 may be provided to ensure the vehicle's stability. The rollers 130 may be wheels that rotate only about their own axes or universal wheels. The rotation of the rollers 130 allows the vehicle to move, reducing friction and urging force when the user pushes the vehicle. The rollers 130 are typically mounted on the end of the base frame away from the frame assembly 200 and may be detachably connected to the base frame. Specifically, the rollers 130 may consist solely of a wheel body, or they may include a wheel body and a support frame for supporting the wheel body, which is connected to the base frame. The support frame can be plugged or snap-fitted with the bottom bracket in a direction perpendicular to the ground, thereby ensuring a stable connection between the bottom bracket and the support frame under the pressure of heavy objects, reducing the risk of the roller 130 falling during normal use of the vehicle. Alternatively, the roller 130 can be plugged or snap-fitted with the bottom bracket in a direction parallel to the ground, thereby facilitating the installation and removal of the roller 130. Of course, in other examples, a side frame of the chassis assembly 100 can also serve as the axle of at least one roller 130, thereby reducing the number of separately provided axles.

[0057] When the carrier is a cart or a chair, the carrier also has a seat for the user to sit or lie on. The frame assembly 200 is a component that supports the seat frame, so that on the one hand, the bearing strength of the seat frame for carrying items or users can be improved, and on the other hand, the support surface of the seat frame can be at a suitable height from the ground, so that the user has a more comfortable experience when sitting or lying on the seat frame. When the seat frame is connected to the frame assembly 200, it can be fixedly installed on the frame assembly 200, or it can be rotatably connected to the frame assembly 200 to change the direction of the seat frame. The frame assembly 200 can be formed by an integrated bracket structure, or it can be composed of multiple support rods, as long as the effect of the frame assembly 200 supporting the seat frame can be achieved. In addition, the bracket itself can be set to a foldable structure, for example, the bracket itself is a retractable structure or the bracket itself includes at least two parts that can be rotated with each other to fold, so that the folding structure of the bracket itself can further facilitate the effect of less space occupied by the carrier after folding.

[0058] The vehicle in the present invention further includes a support assembly 300, which is connected between the frame assembly 200 and the chassis assembly 100. The frame assembly 200 is elastically lifted away from the chassis assembly 100, so that the frame assembly 200 can be cushioned by the support assembly 300 when it is hit, thereby achieving a shock-absorbing effect.

[0059] The setting of the support assembly 300 is equivalent to placing the frame assembly 200 in an elastically suspended state, thereby enabling the frame assembly 200 to cushion impacts from all directions, thereby achieving an all-round shock absorption effect, further improving the shock absorption function of the vehicle. Specifically, the support assembly 300 may include a spring or a shrapnel, etc. Taking the support assembly 300 including a spring as an example, the extension direction of the spring may be a vertical direction or a direction at a certain angle to the vertical direction. There may be one, two, or more springs. When there are at least two springs, the extension directions of all springs may be the same, or the extension directions of at least two springs may be different.

[0060] When the support assembly 300 is connected to the frame assembly 200, it can be fixedly connected or flexibly connected. When the support assembly 300 is fixedly connected to the frame assembly 200, the two can adopt an integrated structure or adopt a plug-in connection method. When the support assembly 300 is flexibly connected to the frame assembly 200, it means that the frame assembly 200 can move relative to the support assembly 300, for example, it can slide or rotate relative to the support assembly 300. This arrangement facilitates the storage of the frame assembly 200. Similarly, when the support assembly 300 is connected to the chassis assembly 100, it can also be fixedly connected or flexibly connected. When the support assembly 300 is flexibly connected to the chassis assembly 100, it means that the support assembly 300 can move relative to the chassis assembly 100, for example, the support assembly 300 can slide or rotate relative to the chassis assembly 100. This arrangement facilitates the storage of the support assembly 300 and the frame assembly 200 together toward the chassis assembly 100. Taking the support assembly 300 including at least two springs as an example, the connection method between all springs and the frame assembly 200 is the same, or the connection method between at least two springs and the frame assembly 200 is different; similarly, the connection method between all springs and the chassis assembly 100 can be the same, or the connection method between at least two springs and the chassis assembly 100 can be different.

[0061] In some embodiments of the present invention, Figure 2 As shown, the elastic member is divided into a first elastic member and a second elastic member, and several of the first elastic members constitute a first shock absorbing assembly 310; several of the second elastic members constitute a second shock absorbing assembly 320, and the first shock absorbing assembly 310 and the second shock absorbing assembly 320 are arranged as a whole along the front-to-back direction.

[0062] By connecting the first shock absorber assembly 310 and the second shock absorber assembly 320 to the opposite front and rear sides of the frame assembly 200 respectively, the elastic suspension effect of the first shock absorber assembly 310 and the second shock absorber assembly 320 on the frame assembly 200 is more balanced, thereby improving the suspension stability of the frame assembly 200.

[0063] Specifically, the first and second elastic members can be the same device, for example, both springs or springs. Alternatively, the first and second elastic members can be different devices, for example, the first spring and the second spring. The elastic expansion and contraction directions of the elastic members in the first and second shock absorber assemblies 310 and 320 can be the same or different. When the elastic expansion and contraction directions of the elastic members in the first and second shock absorber assemblies 310 and 320 are different, for example, the elastic expansion and contraction direction of the first shock absorber assemblies 310 is horizontal, while the elastic expansion and contraction direction of the second shock absorber assemblies 320 is at an angle to both the vertical and horizontal directions; or the elastic expansion and contraction direction of the first shock absorber assemblies 310 is vertical, while the elastic expansion and contraction direction of the second shock absorber assemblies 320 is at an angle to both the vertical and horizontal directions. The first elastic member of the first shock absorber assembly 310 can be connected to the frame assembly 200 using a fixed connection or a hinged connection. The second elastic member of the second shock-absorbing assembly 320 can also be connected to the frame assembly 200 by a fixed connection or a hinged connection. In a stable state, the first elastic member of the first shock-absorbing assembly 310 and the second elastic member of the second shock-absorbing assembly 320 can both be in a compressed state or a stretched state, or one can be in a compressed state and the other can be in a stretched state.

[0064] Of course, in other examples, the support assembly 300 is not limited to including only the first shock-absorbing assembly 310 and the second shock-absorbing assembly 320. For example, in other examples, the support assembly 300 may also include a third shock-absorbing assembly, a fourth shock-absorbing assembly, etc.

[0065] In some embodiments of the present invention, the first elastic member is a tension spring connected to one end of the frame assembly 200 ; the second elastic member is also a tension spring connected to the other end of the frame assembly 200 .

[0066] The first elastic member in the first shock-absorbing assembly 310 mainly functions to connect the frame assembly 200 and provide a buffering effect on the frame assembly 200, while the second elastic member in the second shock-absorbing assembly 320 mainly functions to connect the frame assembly 200 and provide a buffering effect on the frame assembly 200. Of course, it is understandable that the first shock-absorbing assembly 310 may include only the first elastic member, or may further include other components, such as a first connecting piece connected to an end of the first elastic member, the first connecting piece being used to be fixedly connected to the frame assembly 200 or the chassis assembly 100, or the first connecting piece being hinged to the frame assembly 200 or the chassis assembly 100, or the first shock-absorbing assembly 310 may further include a first rod connected to the first elastic member, and the first rod being slidably connected or hinged to the frame assembly 200, etc. Similarly, the second shock-absorbing assembly 320 may include only the second elastic member, or may further include other components, such as a second connecting piece connected to the end of the second elastic member, the second connecting piece being configured to be fixedly connected to the frame assembly 200 or the chassis assembly 100, or the second connecting piece being configured to be hingedly connected to the frame assembly 200 or the chassis assembly 100; or the second shock-absorbing assembly 320 may further include a second rod connected to the second elastic member, the second rod being configured to be slidably connected or hingedly connected to the frame assembly 200. Specifically, the first elastic member and the second elastic member may be connected to the front and rear ends of the frame assembly 200, respectively, or the first elastic member and the second elastic member may be connected to the left and right sides of the frame assembly 200, respectively.

[0067] By connecting the first elastic member to one end of the frame assembly 200 and the second elastic member to the other end of the frame assembly 200, the first elastic member and the second elastic member exert pulling forces on the frame assembly 200 in opposite directions, so that the first elastic member and the second elastic member simultaneously tighten the opposite ends of the frame assembly 200 against each other, thereby ensuring that the frame assembly 200 has relatively good stability and reducing the risk of the frame assembly 200 deviating to one side.

[0068] In other embodiments, the first elastic member may be a compression spring, and the second elastic member may be a tension spring.

[0069] In some embodiments of the present invention, the elastic expansion and contraction direction of at least one of the first elastic member in the first shock-absorbing assembly 310 and the second elastic member in the second shock-absorbing assembly 320 is set at an angle to both the vertical direction and the horizontal direction.

[0070] The first end of the second elastic member is connected to the frame assembly 200, and the second end of the second elastic member is connected to the chassis assembly 100;

[0071] In the front-to-back direction, the first end of the second elastic member is relatively located in front of the second end of the second elastic member;

[0072] In the vertical direction, the first end of the second elastic member is relatively located below the second end of the second elastic member, or the first end of the second elastic member and the second end of the second elastic member are located in the same horizontal direction. When the carrier is loaded, the second elastic member is extended at an angle inclined to the horizontal plane, and when the carrier is not loaded, the second elastic member is extended in the horizontal direction.

[0073] The above-mentioned structural arrangement better realizes the arrangement of the elastic member, facilitates installation and can improve stability during use.

[0074] It should be noted that the term "set at an angle" in the technical solution of the present invention refers to setting at an angle greater than 0° and less than 180°. Specifically, the elastic expansion and contraction direction of the first elastic member is set at an angle with the vertical direction. For example, the elastic expansion and contraction direction of the first elastic member may be an angle greater than 0° with both the vertical and horizontal directions; while the elastic expansion and contraction direction of the second elastic member is the vertical direction or the horizontal direction. For another example, the elastic expansion and contraction direction of the second elastic member may be an angle greater than 0° with both the vertical and horizontal directions; while the elastic expansion and contraction direction of the first elastic member is the vertical direction or the horizontal direction. For another example, the elastic expansion and contraction direction of the first elastic member may be an angle greater than 0° with both the vertical and horizontal directions, while the elastic expansion and contraction direction of the second elastic member also is an angle greater than 0° with both the vertical and horizontal directions; wherein the elastic expansion and contraction direction of the first elastic member may be on the same straight line as the elastic expansion and contraction direction of the second elastic member, or may not be on the same straight line. When the elastic expansion and contraction direction of the first elastic member and the expansion and contraction direction of the second elastic member are not on the same straight line, the elastic expansion and contraction direction of the first elastic member and the expansion and contraction direction of the second elastic member can be set in mirror symmetry, thereby further improving the support stability and balance of the first elastic member and the second elastic member on the frame assembly 200.

[0075] By arranging the elastic expansion and contraction direction of at least one of the first shock-absorbing assembly 310 and the second shock-absorbing assembly 320 to form an angle with both the vertical direction and the horizontal direction, the first shock-absorbing assembly 310 can provide a good elastic buffering effect on the frame assembly 200 in both the vertical direction and the horizontal direction, thereby further improving the all-round shock-absorbing effect on the frame assembly 200.

[0076] In some embodiments of the present invention, at least one of the first elastic member and the second elastic member is hinged to the chassis assembly 100 .

[0077] Specifically, one of the first elastic member and the second elastic member is hinged to the chassis assembly 100 , and the other one is fixedly connected to the chassis assembly 100 ; or both the first elastic member and the second elastic member are hinged to the chassis assembly 100 .

[0078] By hingedly connecting at least one of the first and second elastic members to the chassis assembly 100, at least one of the first and second elastic members can rotate toward the chassis assembly 100, thereby achieving the effect of at least one of the first and second elastic members driving the frame assembly 200 to be retracted toward the chassis assembly 100, thereby reducing the space occupied by the vehicle when not deployed. In addition, by hingedly connecting at least one of the first and second elastic members to the chassis assembly 100, when the frame assembly 200 itself is foldable, the first and second elastic members that are hinged to the chassis assembly 100 can provide favorable conditions for the folding process of the frame assembly 200, reducing the risk of the frame assembly 200 becoming stuck during the folding process.

[0079] In some embodiments of the present invention, the frame assembly 200 is movably connected to the support assembly 300 .

[0080] By movably connecting the frame assembly 200 to the support assembly 300 , the frame assembly 200 can be moved relative to the support assembly 300 , thereby changing the state of the frame assembly 200 or facilitating storage of the frame assembly 200 .

[0081] Specifically, the frame assembly 200 can be slidably connected or hinged relative to the support assembly 300; or a portion of the frame assembly 200 can slide relative to the support assembly 300, while another portion can be hinged relative to the support assembly 300. For example, when the frame assembly 200 is only slidably connected relative to the support assembly 300, the frame assembly 200 can slide toward the support assembly 300. The support assembly 300 may include an elastic member and a connecting member. One end of the elastic member is connected to the connecting member, and the other end is connected to the frame assembly 200. One of the connecting member and the frame assembly 200 may be provided with a slide groove, and the other may be provided with a slider. The slider is slidably disposed in the slide groove, so that the frame assembly 200 compresses the elastic member and slides relative to the connecting member, thereby achieving the effect of the frame assembly 200 being slidably disposed on the support assembly 300 and being retractable therein. It can be understood that when the support assembly 300 includes the above-mentioned first shock absorber assembly 310 and second shock absorber assembly 320, the frame assembly 200 may include a first connecting portion and a second connecting portion that are detachably connected, the first connecting portion being slidably connected to the first shock absorber assembly 310, and the second connecting portion being slidably connected to the second shock absorber assembly 320.

[0082] In some embodiments of the present invention, the frame assembly 200 is hinged to the support assembly 300 .

[0083] When the frame assembly 200 is hinged relative to the support assembly 300, the frame assembly 200 can rotate relative to the support assembly 300, thereby allowing the frame assembly 200 to rotate parallel or nearly parallel to the support assembly 300, thereby achieving a foldable effect of the frame assembly 200 and reducing the space occupied by the vehicle when it is not expanded. In addition, this arrangement also helps to reduce the friction between the frame assembly 200 and the support assembly 300 during relative movement, thereby facilitating user operation.

[0084] In some embodiments of the present invention, the frame assembly 200 includes a plurality of rod brackets, and the plurality of rod brackets are movably connected to enable the vehicle to have a folded state (please refer to Figure 4 He Ru Figure 5 ) and expanded state (please refer to Figure 2 and Figure 3 ).

[0085] By having the frame assembly 200 comprise multiple rod brackets, the multiple rod brackets being movably connected, and the frame assembly 200 having both a folded state and an expanded state, the multiple rod brackets can be in the expanded state, thereby ensuring normal use of the vehicle; and can also be in the folded state, thereby preventing the vehicle from occupying excessive space when not expanded. In this embodiment, the frame assembly 200 formed by the multiple rod brackets is itself foldable, which further reduces the space occupied by the vehicle when not expanded, compared to when the frame assembly 200 as a whole is folded relative to the support assembly 300.

[0086] Specifically, the multiple rod supports can all be connected by hinged connections or all by sliding connections, or some of the multiple rod supports can be connected by hinged connections while others can be connected by sliding connections; or at least some of the multiple rod supports can both rotate and slide relative to each other. The multiple rod supports can collectively form a parallelogram linkage mechanism, a non-parallelogram linkage mechanism, or other polygonal linkage mechanism. Of course, the multiple rod supports can also be movably connected end to end along the same direction.

[0087] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 In the expanded state, the frame assembly includes a first rod support 210, a second rod support 220, a third rod support 230 and a fourth rod support 240.

[0088] The second rod support 220 is rotatably connected to the first rod support 210;

[0089] The third rod support 230 is movably connected to the second rod support 220;

[0090] One end of the fourth rod support 240 is movably connected to the first rod support 210 , and the other end of the fourth rod support 240 is movably connected to the third rod support 230 ;

[0091] One end of the third rod bracket 230 away from the second rod bracket 220 is connected to the second elastic member; the first rod bracket 210 is connected to the first elastic member; the second elastic member is tensionedly arranged between the chassis assembly 100 and the third rod bracket 230; the first elastic member is tensionedly arranged between the chassis assembly 100 and the first rod bracket 210.

[0092] Specifically, the first rod support 210 can be connected to the first elastic member in a fixed or rotatable manner. For example, in this embodiment, one end of the first rod support 210 can be hinged to the first shock-absorbing assembly 310 to form a first hinge portion 201. It should be noted that in the following description, the connection with the first shock-absorbing assembly 310 is to the first elastic member in the first shock-absorbing assembly 310. The second rod support 220 is hinged to the end of the first rod support 210 away from the first shock-absorbing assembly 310 to form a second hinge portion 202. The third rod support 230 is hinged to the second rod support 220 at one end to form a third hinge portion 203, and the third hinge portion 203 does not overlap with the second hinge portion 202. The other end of the third rod support 230 is hinged to the second shock-absorbing assembly 320. The fourth rod support 240 is hinged to the first rod support 210 at one end, and the other end of the fourth rod support 240 is hinged to the third rod support 230.

[0093] The first rod support 210 may include at least two parallel first rods and a first connecting rod connecting the at least two first rods, such that the at least two first rods and the first connecting rod together form the first rod support 210. Alternatively, the first rod support 210 may include a triangular, integrated frame structure. Similarly, the second rod support 220 may include at least two parallel second rods and a second connecting rod connecting the at least two second rods, such that the at least two second rods and the second connecting rod together form the second rod support 220. Alternatively, the second rod support 220 may include a triangular, integrated frame structure. The structures of the third rod support 230 and the fourth rod support 240 may refer to the structure of the first rod support 210 described above and will not be further described here. Alternatively, the third rod support 230 may be a single, linear rod-shaped structure, and the fourth rod support 240 may also be a single, linear rod-shaped structure. When one end of the first rod bracket 210 is hinged to the first shock-absorbing assembly 310, the other end thereof can be extended upward at an angle; when the frame assembly 200 is in the unfolded state, the second rod bracket 220 can be in the same straight line as the first rod bracket 210, thereby increasing the unfolded area of ​​the frame assembly 200 and leaving sufficient space for the seat plate provided on the frame assembly 200.

[0094] By hingedly connecting one end of the first rod bracket 210 to the first shock absorber assembly 310, forming a first hinge portion 201, and hingedly connecting the second rod bracket 220 to the end of the first rod bracket 210 away from the first shock absorber assembly 310, forming a second hinge portion 202, the second rod bracket 220 can rotate relative to the first rod bracket 210, thereby folding the second rod bracket 220 and the first rod bracket 210. This shortens the dimensions of the frame assembly 200 in the direction of arrangement of the first and second rod brackets 210 and 220, reducing the space occupied by the vehicle when not deployed. Furthermore, this arrangement allows for adjustable angles between the first and second rod brackets 210, allowing the second rod bracket 220 to function as a backrest. Furthermore, the second rod bracket 220 can serve as a grip for the user, facilitating movement of the vehicle. Alternatively, the second rod bracket 220 can support the seat plate mounted on the frame assembly 200. By hingedly connecting one end of the third rod support 230 to the second rod support 220, forming the third hinge portion 203, and with the third hinge portion 203 not overlapping the second hinge portion 202, and hingedly connecting the other end of the third rod support 230 to the second shock-absorbing assembly 320, the third rod support 230 can support the second rod support 220 and fold along with the second rod support 220, thereby reducing the risk of interference and jamming between the second and third rod supports 220 and 230. It will be appreciated that when the third rod support 230 rotates about the third hinge portion 203, it can achieve flexible rotation due to the tensile or compressive deformation of the second shock-absorbing assembly 320, further reducing the risk of jamming of the third rod support 230 during rotation. By providing the fourth rod bracket 240, wherein one end of the fourth rod bracket 240 is hinged to the first rod bracket 210 and the other end is hinged to the third rod bracket 230, on the one hand, the fourth rod bracket 240 can connect the third rod bracket 230 and the first rod bracket 210, thereby realizing the effect of connecting the first rod bracket 210, the second rod bracket 220, the third rod bracket 230 and the fourth rod bracket 240 to each other to form a four-bar linkage, thereby improving the supporting strength of the first rod bracket 210, and on the other hand, the fourth rod bracket 240 can also rotate with the rotation of the first rod bracket 210, the second rod bracket 220 and the third rod bracket 230, thereby facilitating the folding of the frame assembly 200 and reducing the risk of the frame assembly 200 being stuck during the folding process.

[0095] Furthermore, one end of the third rod support 230 hinged to the second shock-absorbing assembly 320 forms a fourth hinge portion 204 , and the fourth rod support 240 and the third rod support 230 are hinged between the third hinge portion 203 and the fourth hinge portion 204 ;

[0096] And / or, the fourth rod bracket 240 and the first rod bracket 210 are hinged between the first hinge portion 201 and the second hinge portion 202 .

[0097] With such a configuration, the length of the fourth rod bracket 240 can be reduced while improving the stability of the frame assembly 200 , thereby reducing the space occupied by the frame assembly 200 after being stored.

[0098] In some embodiments of the present invention, one end of the second shock-absorbing assembly 320 away from the third rod bracket 230 is hinged to the chassis assembly 100 to form a fifth hinge portion 321 .

[0099] It is understood that when the frame assembly 200 is folded, if the fourth hinge portion 204 is not stationary, the rotation of the third rod bracket 230 will drive the fourth hinge portion 204 to move, thereby changing the position of the fourth hinge portion 204 and, in turn, changing the extension angle of the second shock absorber assembly 320, thereby causing at least a portion of the second shock absorber assembly 320 to rotate. In this embodiment, by hingedly connecting the end of the second shock absorber assembly 320 away from the third rod to the chassis assembly 100 and forming the fifth hinge portion 321, the second shock absorber assembly 320 can rotate more smoothly, avoiding the risk of jamming.

[0100] By hingedly connecting the end of the second shock absorber assembly 320 away from the third rod to the chassis assembly 100 to form a fifth hinge portion 321, the connection method of the second shock absorber assembly 320 does not interfere with the folding of the entire frame assembly 200, thereby ensuring that the first rod bracket 210, the second rod bracket 220, the third rod bracket 230 and the fourth rod bracket 240 in the frame assembly 200 can be folded together, so that the frame assembly 200 has a good folding effect and the space occupied by the vehicle in the unexpanded state is reduced as much as possible.

[0101] Furthermore, in the expanded state, the plane where the second elastic member is located is approximately the same plane as the plane where the first elastic member is located; such a structural setting can better realize the setting of the first elastic member and the second elastic member, and achieve a better shock absorption effect.

[0102] In a specific embodiment, when the frame assembly 200 is in the expanded state, the first hinge portion 201, the fourth hinge portion 204, and the fifth hinge portion 321 are coplanar. In the expanded state and when unloaded, the second elastic member extends entirely in the front-to-back direction. In the expanded state and when loaded, the second elastic member is tilted.

[0103] By arranging the first hinge portion 201 , the fourth hinge portion 204 and the fifth hinge portion 321 in the same plane when the frame assembly 200 is in the expanded state, the frame assembly 200 is made more balanced, thereby reducing the risk of the frame assembly 200 tilting to one side.

[0104] Based on the solution that the frame assembly 200 includes the above-mentioned second rod bracket 220 , further, in some embodiments of the present invention, the frame assembly 200 also includes a push handle rod assembly 250 , and the push handle rod assembly 250 is connected to the second rod bracket 220 .

[0105] By providing the push rod assembly 250, a gripping position is provided for the user when pushing the vehicle, thereby facilitating the user to push the vehicle. Specifically, when the push rod is connected to the second rod body bracket 220, the push rod assembly 250 can be fixedly connected to the second rod body bracket 220 or movably connected to the second rod body bracket 220. When the push rod assembly 250 is fixedly connected to the second rod body bracket 220, the push rod assembly 250 can be connected to the second rod body bracket 220 by screw connection, pin connection, riveting, clamping, magnetic connection, or welding. When the push rod assembly 250 is fixedly connected to the second rod body bracket 220, it can be detached relative to the second rod body bracket 220 or it can be non-detachable relative to the second rod body. It is understandable that when the push rod assembly 250 is detachably connected to the second rod body bracket 220, it is convenient for the push rod assembly 250 to be replaced and also convenient for the push rod assembly 250 to be stored. When the push handle rod assembly 250 is movably connected to the second rod support 220 , the push handle rod assembly 250 can be rotatably connected to the second rod support 220 or slidably connected to the second rod support 220 .

[0106] Specifically, in one example, the push rod assembly 250 can be an integrally formed U-shaped bracket that is either retractable or integral. In another example, the push rod assembly 250 can simply include at least two spaced-apart support rods connected to the second rod support 220; the support rods can be retractable or fixed. It will be appreciated that telescopic support rods can be adapted to different users and meet their usage habits. Furthermore, by configuring the support rods as telescopic rods, the support rods can be retracted to a shorter distance when the vehicle is stored, thereby reducing the space occupied by the push rod assembly 250. Furthermore, the push rod assembly 250 can also include a connecting rod, with each end connecting the two support rods, thereby increasing the strength of the push rod assembly 250. The connecting rod can be connected to the end of the support rod away from the second rod support 220, thereby forming a U-shaped structure with the two support rods. Alternatively, the connecting rod can be connected between the two ends of the support rod, thereby forming an H-shaped structure with the two support rods. The connecting rod and the supporting rod may be integrally formed, or connected by welding, pin connection, riveting, screw connection, clamping, or the like.

[0107] In another example, the support rod may include at least two sections that are capable of relative rotation. It is understood that when the support rod includes at least two sections that are capable of relative rotation, the relative rotation of the at least two sections can achieve the effect of folding the support rod itself, thereby reducing the space occupied by the carrier when stored.

[0108] Furthermore, the push handle assembly 250 is detachably connected to the second rod support 220, specifically, the support rod of the push handle assembly 250 is detachably connected to the second rod support 220. When the push handle is disassembled, the folded support rod can be removed from the second rod support 220, or the support rod can be first removed from the second rod support 220 and then folded, so that the support rod occupies less storage space, thereby reducing the space occupied by the carrier when it is not expanded.

[0109] Based on the solution that the frame assembly 200 includes the push handle rod assembly 250, further, in some embodiments of the present invention, the push handle rod assembly 250 is movably connected to the second rod body bracket 220 and has a folded state and an expanded state.

[0110] By movably connecting the push handle rod assembly 250 with the second rod body bracket 220 and having a folded state and an expanded state, the space occupied by the push handle rod assembly 250 is reduced after being folded, thereby making the entire carrier occupy less space after being folded; and the push handle rod assembly 250 can provide the user with gripping space when in the expanded state.

[0111] Specifically, the push rod assembly 250 can be slidably connected to the second rod support 220, or can be rotatably connected to the second rod support 220. When the push rod assembly 250 is slidably connected to the second rod support 220, the push rod assembly 250 can slide relative to the second rod support 220 until it overlaps with the second rod support 220, and then drive the second rod support 220 to rotate toward the first rod support 210, and finally rotate to a state that is nearly parallel to the first rod support 210, so that the entire frame assembly 200 occupies a smaller space after being folded. Furthermore, when the push rod assembly 250 is slidably connected to the second rod support 220, multiple positioning assemblies can be provided in its sliding direction, allowing it to stay in any gear position. For example, one of the push handle rod assembly 250 and the second rod body bracket 220 is provided with a plurality of positioning grooves arranged at intervals along the sliding direction of the push handle rod assembly 250, and the other one is provided with an elastic positioning assembly. When the push handle rod assembly 250 is pushed with force, the elastic positioning assembly can move from one of the positioning grooves to another positioning groove. When the pushing force on the push handle rod assembly 250 is stopped, the elastic positioning assembly is stuck in the current positioning groove, thereby achieving a more stable positioning effect, so that the length of the push handle rod assembly 250 can adapt to different users.

[0112] When the push rod assembly 250 is rotatably connected to the second rod support 220, the push rod assembly 250 can rotate relative to the second rod support 220 until it overlaps with the second rod support 220, thereby driving the second rod support 220 to rotate toward the first rod support 210 and ultimately rotate to a position nearly parallel to the first rod support 210, thereby reducing the space occupied by the frame assembly 200 after folding. Furthermore, when the push rod assembly 250 is rotatably connected to the second rod support 220, a positioning structure can be provided in the rotation direction so that it can be stopped at any gear position. For example, one of the push rod assembly 250 and the second rod support 220 is provided with a plurality of positioning slots spaced apart along the rotation direction of the push rod assembly 250, and the other one is provided with an elastic positioning assembly. When the push rod assembly 250 is rotated with force, the elastic positioning assembly can be moved from one positioning slot to another positioning slot. When the pushing force on the push rod assembly 250 is stopped, the elastic positioning assembly is snapped into the current positioning slot, thereby achieving a more stable positioning effect, so that the angle of the push rod assembly 250 can be adapted to different users. Alternatively, the push rod assembly 250 and the second rod support 220 are engaged by a gear set, so that the push rod assembly 250 can stay in any gear position when rotating relative to the second rod support 220.

[0113] When the handlebar assembly 250 moves relative to the second rod bracket 220 for folding, the handlebar assembly 250 can be driven to move to the side of the second rod bracket 220 where it connects to the third rod bracket 230, thereby reducing the space occupied by the frame assembly 200 in the thickness direction of the vehicle after folding and storage, making the folded vehicle lighter and thinner. Furthermore, when the handlebar assembly 250 rotates or slides to a position substantially parallel to the second rod bracket 220, the projection of the handlebar assembly 250 on the second rod bracket 220 and the projection of the third rod bracket 230 on the second rod bracket 220 do not overlap, thereby further reducing the space occupied by the frame assembly 200 in the thickness direction of the vehicle after folding and storage.

[0114] In some embodiments of the present invention, please refer to Figures 2 to 5 The chassis assembly 100 includes a support body 110 and a support arm 120. One end of the support arm 120 is connected to the support body 110, and the other end extends away from the support body. In this embodiment, the support arm 120 extends upward and is connected to the support assembly 300. In this embodiment, the second elastic member is rotatably mounted on the support arm.

[0115] The third rod support 230 is rotatably connected to the second rod support 220;

[0116] One end of the fourth rod support 240 is rotatably connected to the first rod support 210 , and the other end of the fourth rod support 240 is rotatably connected to the third rod support 230 ;

[0117] Please refer to Figure 4 and Figure 5 In the folded state, the second rod support 240 rotates toward the first rod support 210, the first rod support 210 is folded toward the chassis assembly 100, the third rod support 230 rotates toward the chassis assembly 100, and the third rod support 230 rotates toward the second rod support 220;

[0118] The second elastic member rotates toward the supporting arm 120 .

[0119] The bracket body 110 can be a frame structure formed by polygonal enclosed elements or a plate structure. When the bracket body 110 is a frame structure, the bracket body 110 can be an integrated structure, or the various connection sections in the frame structure can be connected by screw connection, clamping, welding, etc.

[0120] By connecting one end of the support arm 120 to the support body 110 and the other end extending upward to connect to the support assembly 300, the height of the support assembly 300 and the frame assembly 200 is increased, thereby reducing the risk of interference between the frame assembly 200 and the roller 130 in the vehicle connected to the support body 110. Furthermore, the risk of interference between the support assembly 300 and the support body 110 during movement or extension is reduced.

[0121] It should be noted that the upward extension of the other end of the support arm 120 is based on the normal extended state of the carrier. The upward extension of the other end of the support arm 120 can be understood as extending the other end of the support arm 120 vertically upward from the ground, or extending upward at an angle to the vertical ground.

[0122] The support arm 120 includes a body and a transverse extension portion provided on the body, wherein the transverse extension portion extends from the body toward the frame assembly 200 to form an escape space between the transverse extension portion and the body;

[0123] The second elastic member is rotatably mounted on the transverse extension portion. When the carrier is in a folded state, the second elastic member is located in the avoidance space.

[0124] In a specific embodiment, one end of the support arm 120 away from the bracket body 110 is bent toward the frame assembly 200 .

[0125] When the end of the support arm 120 away from the bracket body 110 bends toward the frame assembly 200, the support arm 120 forms an L-shaped structure, thereby forming an escape groove structure within the support arm 120. When the support assembly 300 is able to rotate relative to the chassis assembly 100, the escape groove can provide an escape space for the support assembly 300 during the rotation process, thereby reducing the risk of interference between the support assembly 300 and the chassis assembly 100. Specifically, when the end of the support arm 120 away from the bracket body 110 bends toward the frame assembly 200, the bend can be at a right angle or in an arc shape.

[0126] Of course, in other examples, the support arm 120 may also be in a straight line, that is, the end of the support arm 120 away from the bracket body 110 is not bent but is in a straight line. In order to reduce the risk of interference between the support arm 120 and the support assembly 300, a connecting shaft may be protruded from one side of the support assembly 300, and an axis hole may be opened at the end of the support arm 120 away from the bracket body 110, and the connecting shaft passes through the axis hole, so that the support assembly 300 is completely located on one side of the support arm 120, and a small gap is left between the support assembly 300 and the side wall of the support arm 120, so that the support assembly 300 is not affected by the support arm 120 during the rotation process, and the risk of interference of the support arm 120 with the support assembly 300 can still be avoided.

[0127] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
