Description
Technical Field
[0001] This utility model relates to the field of vehicle transportation technology, specifically to a base for supporting a four-wheeled electric vehicle. Background Technology
[0002] Before transportation, vehicles need to be properly packaged, including securing the wheels. Securing the wheels prevents them from rotating due to bumps, tilting, or emergency braking during transport, thus avoiding displacement or mechanical damage. Current wheel-secured supports are only suitable for specific wheel sizes; for different wheel models, custom molds are required, resulting in poor adaptability. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a base for supporting a four-wheeled electric vehicle that can accommodate various types of wheels.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A base for supporting a four-wheeled electric vehicle includes a base body. The upper side of the base body has a receiving groove for placing a wheel. The receiving groove is provided with a fixing mechanism for fixing the wheel. The fixing mechanism includes a bottom support member and two symmetrically arranged side wall support members. When the wheel is placed on the bottom support member, the two side wall support members can drive the wheel to clamp it. The base body is also provided with an adjustable strap for fixing the wheel in the receiving groove.
[0006] The working principle is as follows:
[0007] After the four wheels of the four-wheeled electric vehicle are placed into the receiving slots, the edges of the slots abut against the outer edges of the wheels. The bottom support supports the bottom of the wheels, and the two side wall supports automatically clamp onto both sides of the wheels under the action of the bottom support. Finally, the straps are used to press the upper side of the wheels firmly into the receiving slots. The bottom support and side wall supports can be adaptively adjusted according to the wheel size, and the length of the straps can also be adjusted according to the wheel size. Using this structure, the upper, lower, sides, and outer edges of the wheel can be fixed from all directions, providing a good fixing effect and being suitable for various wheel models.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] By combining bottom support, side wall support and straps, it is possible to fix different types of wheels in all directions, which not only has a good fixing effect, but also has strong adaptability.
[0010] In a preferred embodiment of this utility model, the opposite sidewalls of the receiving groove are respectively provided with first sealing grooves. The sidewall support includes a first piston, a pressing plate, and a first connecting rod connected between the first piston and the pressing plate. The first piston is located in the first sealing groove and cooperates with the first sealing groove to form a first sealing cavity. The bottom of the receiving groove is provided with a second sealing groove. The bottom support includes a second piston, a bottom support plate, and a second connecting rod connected between the second piston and the bottom support plate. The second piston is located in the second sealing groove and cooperates with the second sealing groove to form a second sealing cavity. A spring is provided between the second piston and the bottom of the second sealing groove. A connecting pipe is provided between the second sealing cavity and the two first sealing cavities.
[0011] The working principle is as follows:
[0012] After the wheel is placed in the receiving slot, the vehicle's own weight presses down on the bottom support plate, and the second piston moves downward, pushing the gas in the second sealing chamber into the two first sealing chambers. At this time, the internal pressure of the first sealing chambers on both sides increases, and the first piston is pushed outward by the pressure, thereby causing the two clamping plates to clamp the wheel. When the vehicle is lifted, the spring's reset function pushes the second piston back to the initial position, the internal pressure of the first sealing chambers on both sides decreases, and the first piston moves inward. Beneficial effects
[0013] Through the linkage design of the three sealed chambers, the weight of the wheel can be converted into a uniform clamping force, realizing the automatic clamping function of the wheel; in addition, since the gas pressure is automatically adjusted according to the vehicle weight, the clamping force applied by the abutment plate is always matched with the vehicle weight, thus avoiding being too tight or too loose.
[0014] The spring design not only functions to reset the vehicle when it is lifted, but also acts as a buffer when the bottom support plate is pressed down, preventing a sudden increase in pressure in the first sealing chambers on both sides when pressed down, thus ensuring a more stable clamping force of the clamping plates on both sides.
[0015] In a preferred embodiment of this utility model, the abutment plate is provided with a rubber layer on the side near the wheel.
[0016] Beneficial effects: The rubber layer design increases friction with the wheel, resulting in a better fixation effect.
[0017] In a preferred embodiment of the present invention, the bottom support plate is arc-shaped and has a rubber layer on its upper side.
[0018] Beneficial effects: By designing the bottom support plate as an arc shape, the contact area between it and the wheel can be increased. At the same time, the rubber layer can be added to increase the friction with the wheel and enhance the fixing effect.
[0019] In a preferred embodiment of this utility model, the strap is positioned above the receiving groove. One end of the strap is connected to the base body, and a locking assembly is provided between the other end and the base body. The locking assembly includes a mounting base fixed to the base body, and the mounting base has a mounting cavity. An L-shaped rotating plate is mounted in the mounting cavity via a torsion spring. A slot communicating with the mounting cavity is provided on the upper side of the mounting base. The locking assembly also includes a plug plate connected to the strap. A through hole is provided at the lower part of the plug plate. After the plug plate is inserted into the slot, one end of the rotating plate can extend into the through hole.
[0020] In a preferred embodiment of the present invention, the base body is provided with at least two receiving grooves, and a plurality of light-reducing holes are provided on the base body between two adjacent receiving grooves.
[0021] In a preferred embodiment of this utility model, the connecting pipes between the two first sealing cavities and the second sealing cavity are of the same length.
[0022] Beneficial effects: By setting the length of the two connecting pipes to be the same, it can be ensured that the path length of the gas on both sides is the same, thereby increasing the pressure inside the first sealing chamber on both sides synchronously, and the clamping plates on both sides clamp inward synchronously, which can make the force on both sides of the wheel more uniform and symmetrical.

Detailed Implementation
[0031] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.
[0032] In the description of this application, the terms "first", "second", etc. are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0033] See Figure 1 and Figure 2 As shown, this embodiment discloses a base for supporting a four-wheeled electric vehicle, including a base body 1. Two receiving slots 11 are formed on the upper side of the base body 1. The two front wheels or two rear wheels of the four-wheeled electric vehicle are respectively placed in these two receiving slots 11. A plurality of light-reducing holes 12 are evenly distributed on the base body 1 between the two receiving slots 11. In other embodiments, four receiving slots 11 may be formed on the upper side of the base body 1, and a plurality of light-reducing holes 12 are evenly distributed between the four adjacent receiving slots 11.
[0034] See Figure 3 As shown, the receiving groove 11 is provided with a fixing mechanism for fixing the wheel. The fixing mechanism includes a bottom support 5 and two symmetrically arranged side wall supports 4. When the wheel is placed on the bottom support 5, the two side wall supports 4 can clamp the wheel.
[0035] For details, see Figure 4As shown, the opposite sidewalls of the receiving groove 11 are respectively provided with first sealing grooves. The sidewall support member 4 includes a first piston 42, a pressing plate 44, and a first connecting rod 43 connecting the first piston 42 and the pressing plate 44. The first piston 42 is located in the first sealing groove and cooperates with the first sealing groove to form a first sealing cavity 41. The bottom of the receiving groove 11 is provided with a second sealing groove. The bottom support member 5 includes a second piston 52, a bottom support plate 54, and a second connecting rod 53 connecting the second piston 52 and the bottom support plate 54. The second piston 52 is located in the second sealing groove and cooperates with the second sealing groove to form a second sealing cavity 51. A connecting pipe 56 is provided between the second sealing cavity 51 and the two first sealing cavities 41, wherein the two connecting pipes 56 are of the same length.
[0036] When in use, the wheel is placed into the receiving groove 11, and the weight of the vehicle presses down the bottom support plate 54, causing the second piston 52 to move downward, thereby pushing the gas in the second sealing chamber 51 into the two first sealing chambers 41. At this time, the internal pressure of the two first sealing chambers 41 increases synchronously, and the first piston 42 is pushed outward by the pressure, thereby causing the two clamping plates 44 to clamp the wheel at the same time.
[0037] Furthermore, a rubber layer is bonded to the side of the abutment plate 44 near the wheel, and the bottom support plate 54 is arc-shaped with a rubber layer also bonded to its upper side. The arc-shaped design of the bottom support plate 54 increases its contact area with the wheel, and the rubber layers on the abutment plate 44 and the bottom support plate 54 increase the friction with the wheel, thus enhancing the fixing effect.
[0038] Furthermore, a spring 55 is fixed between the second piston 52 and the bottom of the second sealing groove. The design of the spring 55 allows it to push the second piston 52 to its initial position when the vehicle is lifted, and it also acts as a buffer when the bottom support plate 54 is pressed down, so as to prevent a sudden increase in pressure in the first sealing cavities 41 on both sides when pressed down, thereby ensuring a more stable clamping force of the clamping plates 44 on both sides.
[0039] See Figure 2 and Figure 5 As shown, the base body 1 is also equipped with an adjustable strap 2, which is located above the receiving groove 11 and is used to fix the wheel in the receiving groove 11. The length of the strap 2 is adjusted by sliding the position of the D-ring buckle. Specifically, one end of the strap 2 is equipped with a D-ring buckle, and the end of the strap 2 is fixedly connected to the middle post of the D-ring buckle. The base body 1 is fixed with a connector at the corresponding position. The upper part of the connector is provided with a through hole, and the other end of the strap 2 passes through the through hole and slides through the middle post of the D-ring buckle.
[0040] See Figure 6 and Figure 7As shown, a locking assembly 3 is provided between the other end of the strap 2 and the base body 1. The locking assembly 3 includes a mounting base 31 fixed to the base body 1. The mounting base 31 has a mounting cavity 312. An "L"-shaped rotating plate 32 is mounted in the mounting cavity 312 via a torsion spring 33. The upper side of the mounting base 31 has a slot 311 communicating with the mounting cavity 312. Without external force, the lower end of the rotating plate 32 passes into the slot 311. The locking assembly 3 also includes a plug-in plate 6 fixed to the strap 2. The lower part of the plug-in plate 6 has a through hole 61. The plug-in plate 6 can be locked after being inserted into the slot 311. In use, when the plug-in plate 6 is inserted into the slot 311, the plug-in plate 6 pushes the rotating plate 32 downward, and the rotating plate 32 rotates counterclockwise. After the plug-in plate 6 is successfully inserted into the slot 311, the rotating plate 32 returns to its original position under the action of the torsion spring 33, and the lower end of the rotating plate 32 passes into the through hole 61, thus locking. To remove, move the upper end of the rotating plate 32 as shown in the image. Figure 6 The direction of F in the middle causes the rotating plate 32 to rotate counterclockwise, and the lower end of the rotating plate 32 exits the through hole 61, allowing it to be removed. Furthermore, to facilitate the movement of the rotating plate 32, the mounting base 31 is provided with a clearance groove 313 on the side near the rotating plate 32.
[0041] The usage method of this embodiment is as follows:
[0042] After the four wheels of the four-wheeled electric vehicle are placed into the receiving groove 11, the edge of the receiving groove 11 abuts against the outer edge of the wheel. The bottom support 5 supports the bottom of the wheel, and the two side wall support members 4 are automatically clamped to both sides of the wheel under the action of the bottom support 5. Finally, the strap 2 is used to press the upper side of the wheel into the receiving groove 11.
[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
