[0002] At present, electric two-wheeled vehicles (such as motorcycles) are becoming more and more popular among consumers because of their flexibility and convenience, which can avoid traffic jams and save time. Electric two-wheeled vehicles usually include a frame, a seat and wheels. The seat is arranged on the frame, and the wheels are arranged at the front and rear ends of the frame. Among them, the seat is generally locked to the frame by a seat lock, or a threaded part (such as a bolt) is installed from the rear end of the frame to lock the seat. However, the above two seat locking methods require the cooperation of multiple threaded parts, which is not conducive to the rapid disassembly and replacement of the seat. Summary of the invention

[0003] Based on this, it is necessary to provide a vehicle in view of the problem that the existing vehicle seats are difficult to disassemble and replace.

[0004] A vehicle comprises: a frame, a seat and a plurality of mounting structures;

[0005] The mounting structure is arranged between the frame and the seat and comprises a limiting seat and a limiting head, the limiting seat is provided with a limiting cavity, the limiting head can cooperate with the limiting cavity through the movement of the seat in the first direction, so as to limit the seat in the second direction and the third direction, the first direction, the second direction and the third direction are perpendicular to each other and the third direction is the up-down direction;

[0006] The limiting seat of one of the mounting structures is further provided with a locking portion, and the locking portion is used to lock the vehicle seat and the vehicle frame through a screw member.

[0007] In one embodiment, the plurality of mounting structures are respectively disposed at the front and rear ends of the vehicle seat, and the first direction is the front-rear direction.

[0008] In one embodiment, the locking portion is disposed on the limiting seat at the rear end of the frame.

[0009] In one of the embodiments, a plurality of support seats are further provided on a side of the frame facing the seat, and the support seats abut against a middle portion of the seat.

[0010] In one of the embodiments, at least a portion of the support base is provided with a mounting frame.

[0011] In one embodiment, the limiting head is arranged on a side of the seat facing the frame, and the limiting seat is arranged on a side of the frame facing the seat.

[0012] In one embodiment, the limiting seat is formed by bending a sheet metal part.

[0013] In one embodiment, the limiting cavity runs through the entire thickness of the sheet metal component and includes a limiting portion and an avoiding portion;

[0014] The limiting portion extends from the bent portion of the sheet metal component along the first direction;

[0015] The avoidance portion extends along the third direction toward the bending portion until it communicates with the limiting portion, wherein a width of the avoidance portion in the second direction is greater than a width of the limiting portion in the second direction.

[0016] In one embodiment, the limit head includes a mounting rod connected to the frame or the seat and a stop protrusion connected to the mounting rod;

[0017] The outer diameter of the mounting rod is smaller than or equal to the width of the limiting portion in the second direction;

[0018] The outer diameter of the stop protrusion is less than or equal to the width of the avoidance portion in the second direction, and is greater than the width of the limiting portion in the second direction.

[0019] In one embodiment, the locking portion includes a connected horizontal section and a vertical section, the horizontal section is connected to the corresponding limit seat, and the vertical section has a fastening hole for the threaded member to pass through.

[0020] When installing a vehicle seat, the seat can be moved in a first direction first so that the limiting head of the installation structure can slide into the limiting cavity of the limiting seat, thereby limiting the seat in the second direction and the third direction; then, a threaded member is installed on the locking portion of the limiting seat to lock the seat and the frame, thereby preventing the seat from detaching from the frame in a direction opposite to the first direction.

[0021] When replacing the vehicle seat, the threaded member on the locking portion can be removed first to release the lock between the cushion seat and the frame; then, the seat is moved in a direction opposite to the first direction so that the limiting head slides out of the limiting cavity of the limiting seat, thus realizing the removal of the seat, and then the new seat can be installed on the frame.

[0022] The above-mentioned vehicle, by arranging a plurality of mounting structures between the frame and the seat, can limit the position of the seat by using the cooperation between the limiting seat and the limiting head of the mounting structure, and then install a threaded member on the locking part of one of the mounting structures to lock the seat on the frame. It can be seen that in the entire process of disassembling and assembling the seat, only one threaded member needs to be installed or removed from the locking part to achieve locking or unlocking of the seat and the frame, so that the vehicle seat can be quickly installed and disassembled.

[0033] At present, electric two-wheeled vehicles (such as motorcycles) are becoming more and more popular among consumers because of their flexibility and convenience, which can avoid traffic jams and save time. Electric two-wheeled vehicles usually include a frame, a seat and wheels. The seat is arranged on the frame, and the wheels are arranged at the front and rear ends of the frame. Among them, the seat is generally locked to the frame by a seat lock, or a threaded part (such as a bolt) is installed from the rear end of the frame to lock the seat. However, the above two seat locking methods require the cooperation of multiple threaded parts, which is not conducive to the rapid disassembly and replacement of the seat.

[0034] In this regard, as shown in FIGS. 1 to 4 , an embodiment of the present application provides a vehicle 10, which includes a frame 200, a seat 100, and a plurality of mounting structures 300. Referring to FIG. 2 , the mounting structure 300 is disposed between the frame 200 and the seat 100 and includes a limiting seat 320 and a limiting head 310. The limiting seat 320 is provided with a limiting cavity 321. The limiting head 310 can cooperate with the limiting cavity 321 through the movement of the seat 100 in the first direction to limit the seat 100 in the second direction and the third direction. The first direction, the second direction and the third direction are perpendicular to each other and the third direction is the up-down direction. The limiting seat 320 of one of the mounting structures 300 is also provided with a locking portion 400, which is used to lock the seat 100 with the frame 200 through a screw member.

[0035] The vehicle 10 of this embodiment can be a two-wheeled vehicle, such as a motorcycle; or a three-wheeled vehicle, such as an electric three-wheeled vehicle. As an example, the vehicle 10 further includes a plurality of wheels, which are arranged on the frame 200. It is understood that when the vehicle 20 is a two-wheeled vehicle, the number of wheels is at least 2, and they are arranged on the front and rear ends of the frame 200; when the vehicle 30 is a three-wheeled vehicle, the number of wheels is at least 3, and they are also arranged on the front and rear ends of the frame 200.

[0036] As shown in FIG. 2 , the limiting head 310 may be disposed on the side of the seat 100 facing the frame 200, and the limiting seat 320 may be disposed on the side of the frame 200 facing the seat 100. Of course, in some other embodiments, the limiting head 310 may be disposed on the side of the frame 200 facing the seat 100, and the limiting seat 320 may be disposed on the side of the seat 100 facing the frame 200; or the limiting head 310 and the limiting seat 310 of a part of the mounting structure 300 may be disposed on the side of the seat 100 facing the frame 200, and the limiting head 310 and the limiting seat 320 of another part of the mounting structure 300 may be disposed on the side of the frame 200 facing the seat 100.

[0037] The following is an example in which the limit head 310 is disposed on the vehicle seat 100 and the limit seat 320 is disposed on the vehicle frame 200 to illustrate the disassembly and assembly process of the vehicle seat 100:

[0038] When installing the seat 100 of the vehicle 10, the seat 100 can be moved along the first direction first, so that the limiting head 310 of the mounting structure 300 can slide into the limiting cavity 321 of the limiting seat 320, so that the seat 100 can be limited in the second direction and the third direction; then, a threaded member is installed on the locking portion 400 of the limiting seat 320 to lock the seat 100 and the frame 200, so as to prevent the seat 100 from being separated from the frame 200 in a direction opposite to the first direction.

[0039] When replacing the seat 100 of the vehicle 10, the threaded member on the locking portion 400 can be removed first to release the lock between the seat 100 and the frame 200; then the seat 100 is moved in a direction opposite to the first direction, so that the limiting head 310 slides out of the limiting cavity 321 of the limiting seat 320, and the seat 100 is disassembled. After that, the new seat 100 can be installed on the frame 200.

[0040] The vehicle 10 of this embodiment, by providing a plurality of mounting structures 300 between the vehicle frame 200 and the vehicle seat 100, can limit the position of the vehicle seat 100 by using the cooperation between the limiting seat 320 and the limiting head 310 of the mounting structure 300, and then install a screw member on the locking portion 400 of one of the mounting structures 300 to lock the vehicle seat 100 on the vehicle frame 200. It can be seen that in the entire process of disassembling and assembling the vehicle seat 100, only one screw member needs to be installed or removed from the locking portion 400 to achieve locking or unlocking of the vehicle seat 100 and the vehicle seat 100 of the vehicle 10 can be quickly installed and disassembled.

[0041] As shown in Figures 1 to 4, in this embodiment, a plurality of mounting structures 300 are respectively arranged at the front and rear ends of the seat 100, and the first direction is the front-to-back direction. The seat 100 or the frame 200 may have dimensional deviations during the production process, so that the seat 100 cannot be centrally mounted on the frame 200. When the seat 100 is connected to the front and rear ends of the frame 200 through the mounting structures 300, the seat 100 will be arranged forward or backward. Since the front-to-back widths of the seat 100 and the frame 200 are both greater than the left-to-right widths, the front or rear deviation of the seat 100 is not as obvious as the left or right deviation, which can improve the aesthetic appearance of the vehicle 10. It can be understood that the second direction is the left-to-right direction.

[0042] Of course, in some other embodiments, the plurality of mounting structures 300 may also be respectively disposed on the left and right sides of the vehicle seat 100, and the first direction is the left-right direction. It is understandable that when the vehicle seat 100 is installed, the stopper 310 may be slid into the stopper cavity 321 of the corresponding stopper seat 320 along the left-right direction; when the vehicle seat 100 is removed, the stopper 310 may be pulled out of the stopper cavity 321 of the corresponding stopper seat 320 along the left-right direction.

[0043] It should be noted that the directions of “front”, “rear”, “left” and “right” in the full text shall be based on the directions shown in FIG. 1 .

[0044] The number of the mounting structures 300 may be two, and the two mounting structures 300 are respectively arranged at the front and rear ends of the vehicle 10. Each mounting structure 300 may include a limiting seat 320 and two limiting heads 310, and the limiting seat 320 may be provided with a limiting cavity 321 at both ends of the second direction, that is, the four front, rear, left, and right corners of the seat 100 are all limited by the cooperation of the limiting heads 310 and the limiting cavities 321. In this way, the structure of the vehicle 10 can be simplified, and the firmness of the installation of the seat 100 on the frame 200 can also be ensured.

[0045] Of course, in some other embodiments, the number of mounting structures 300 can be greater than 2, such as 3, 4 or more, and the number of the limiting heads 310 and the limiting seats 320 of each mounting structure 300 can be set accordingly according to actual needs. For example, three mounting structures 300 are set on the vehicle 10, wherein one mounting structure 300 is set at the front end of the vehicle seat 100, and the limiting seats 320 of the mounting structure 300 are respectively provided with a limiting cavity 321 on the left and right sides; the other two mounting structures 300 are respectively provided at the left and right sides of the rear end of the vehicle seat 100, and the limiting seats 320 of the two mounting structures 300 are respectively provided with a limiting cavity 321. As another example, four mounting structures 300 are provided on the vehicle 10, wherein two mounting structures 300 are provided on the left and right sides of the front end of the seat 100, and the other two mounting structures 300 are provided on the left and right sides of the rear end of the seat 100, respectively. The limiting seats 320 of the four mounting structures 300 are each provided with a limiting cavity 321.

[0046] As shown in Fig. 4, the locking part 400 is disposed on the limiting seat 320 at the rear end of the frame 200. If the locking part 400 is disposed at the front end of the frame 200, the screw on the locking part 400 is exposed to the front of the vehicle 10, which makes the vehicle 10 unsightly.

[0047] 4, the locking portion 400 may include a connected horizontal section 411 and a vertical section 412, the horizontal section 411 is connected to the corresponding limit seat 320, and the vertical section 412 has a fastening hole 4121 for a screw member to pass through. The locking portion 400 of this structure is simple in structure. The locking portion 400 can be formed by bending a sheet metal part, wherein the horizontal section 411 of the locking portion 400 can be connected to the corresponding limit seat 320 by welding, integral molding, etc.

[0048] Referring to FIG. 2 , a connecting ear plate 110 is provided on the side of the vehicle seat 100 facing the vehicle frame 200. The connecting ear plate 110 also has a mounting hole 111. The screw member is inserted into the fastening hole 4121 and the mounting hole 111, so that the locking part 400 and the connecting ear plate 110 can be locked. The connecting ear plate 110 can be connected to the saddle of the vehicle seat 100 by bonding, screw members or integral molding. Among them, the vehicle seat 100 can be shown in FIG. 1, including a saddle and a cushion, the cushion is arranged on the saddle, and the saddle is installed on the vehicle frame 200. It should be noted that the vehicle seat 100 of the vehicle 10 shown in FIG. 2 to FIG. 4 does not have a cushion.

[0049] When the frame 200 is tilted downward in the front-to-back direction, the height difference between the frame 200 and the seat 100 gradually increases in the front-to-back direction. In this regard, referring to FIG. 3 , a lifting structure 230 is further provided on the side of the frame 200 facing the seat 100, and a limiting seat 320 of the mounting structure 300 located at the rear end of the seat 100 is provided on the lifting structure 230. Referring to FIG. 3 , the lifting structure 230 may include a connecting seat 231 and two fixing seats 232, the two fixing seats 232 are respectively provided on the left and right sides of the frame 200, and the connecting seat 231 is provided between the two fixing seats 232 and connected to the corresponding limiting seats 320. Specifically, the fixing seat 232 may be substantially in an inverted U-shape, and the connecting seat 231 may be substantially in a "human" shape.

[0050] In order to prevent the middle part of the seat 100 from being sunken and deformed downward during the riding of the vehicle 10, as shown in FIG3 and FIG4, a plurality of support seats 210 are further provided on the side of the frame 200 facing the seat 100, and the support seats 210 abut against the middle part of the seat 100. The support seats 210 can support the middle part of the seat 100. The support seats 210 can be generally in an inverted U shape as shown in FIG1, and can be provided on the frame 200 by welding, screws, etc.

[0051] The number of the support bases 210 can be set according to actual conditions, as long as the vehicle seat 100 can be effectively supported. For example, the number of the support bases 210 can be 2, and the 2 support bases 210 are respectively arranged on the left and right sides of the vehicle frame 200. For example again, the number of the support bases 210 can be 4, of which 2 support bases 210 are arranged on the left side of the vehicle frame 200, and the other 2 support bases 210 are arranged on the right side of the vehicle frame 200.

[0052] Further, as shown in FIG. 4 , at least a portion of the support base 210 is provided with a mounting bracket 220. The mounting bracket can be used to mount corresponding components of the vehicle 10, such as a vehicle charger. The mounting bracket 220 can also be generally in an inverted U-shape, and can be mounted on the support base 210 by welding, screwing, etc. Among them, the mounting bracket 220 can be provided with a threaded hole, and the vehicle charger can be installed by threading a screw.

[0053] Among them, a support seat 210 can be provided on the left and right sides of the frame 200, and each support seat 210 is provided with a mounting frame 220. At this time, the two fixed seats 232 of the lifting structure 230 can also be provided with a mounting frame 220. The vehicle charger can be installed on the frame 200 through the cooperation of these four mounting frames 220; of course, two support seats 210 can be provided on the left and right sides of the frame 200 respectively, and each support seat 210 is provided with a mounting frame 220. The vehicle charger can also be installed through the cooperation of these four mounting frames 220. In this case, there is no need to set the mounting frame 220 on the two fixed seats 232 of the lifting structure 230.

[0054] Considering the processing technology and the weight of the entire frame 200, as shown in Figures 1 to 4, the limit seat 320 can be formed by bending a sheet metal part. The specific structure of the limit seat 320 can be formed by bending the sheet metal part accordingly according to the needs. For example, as shown in Figure 3, the limit seat 320 located at the front end of the frame 200 can be roughly in an inverted "U" shape through the secondary bending of the sheet metal part, that is, the limit seat 320 located at the front end of the frame 200 has two front and rear bending parts; the limit seat 320 located at the rear end of the frame 200 can be roughly in an inverted "Z" shape through the secondary bending of the sheet metal part, that is, the limit seat 320 located at the rear end of the frame 200 has two upper and lower bending parts.

[0055] The limiting seat 320 can be disposed on the vehicle frame 200 by welding, screws, etc.

[0056] Continuing to refer to FIG3 , the limiting cavity 321 may penetrate the entire thickness of the sheet metal and include a limiting portion 3211, which extends from the bent portion of the sheet metal along the first direction. When the limiting head 310 slides toward the limiting portion 3211 of the limiting cavity 321 driven by the vehicle seat 100, if the limiting head 310 does not enter the limiting cavity 321 due to an operation error and collides with the bent portion of the sheet metal, the bent portion of the sheet metal has the highest strength compared to other parts, so that the sheet metal is not easily deformed.

[0057] It is understandable that, in order to ensure that the limiting head 310 can smoothly enter the limiting cavity 321, as shown in FIG3 , the limiting cavity 321 further includes an avoidance portion 3212, which extends along the third direction toward the bending portion of the sheet metal until it communicates with the limiting portion 3211 of the limiting cavity 321, wherein the width of the avoidance portion 3212 in the second direction is greater than the width of the limiting portion 3211 in the second direction. When the limiting head 310 is driven by the vehicle seat 100 and slides toward the limiting cavity 321, the limiting head 310 can first pass through the avoidance portion 3212 and slide into the limiting portion 3211.

[0058] The limiting head 310 may include a mounting rod connected to the vehicle seat 100 and a stopper protrusion connected to the mounting rod; the outer diameter of the mounting rod is less than or equal to the width of the limiting portion 3211 in the second direction; the outer diameter of the stopper protrusion is less than or equal to the width of the avoidance portion 3212 in the second direction, and is greater than the width of the limiting portion 3211 in the second direction. After the limiting head 310 slides into the limiting cavity 321, the mounting rod is accommodated in the limiting portion 3211, and the stopper protrusion abuts against the limiting seat 320, which can prevent the limiting head 310 from moving upward, and the vehicle seat 100 can be prevented from detaching from the vehicle frame 200 along the up and down direction. It can be understood that when the limiting head 310 is set on the vehicle frame 200, the mounting rod of the limiting head 310 is connected to the vehicle frame 200. The stopper protrusion may be an annular protrusion, which may be connected to the mounting rod by bonding, clamping or integral molding.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
