[0037] See Figure 1 This utility model provides a vehicle maintenance lifting device 100, including a support base 110 and a support platform 120. The support platform 120 has four sides, namely the front, rear, left, and right sides, and each side includes an outer surface and an inner surface. These four sides together form the main outline of the support platform 120. The front and rear sides a of the support platform 120 are provided with trapezoidal grooves 122 that are recessed inward. The inward recess of the trapezoidal grooves 122 forms a protrusion 300 on the inner surface of the support platform 120 (see...). Figure 2 The support base 110 is also provided with a positioning groove 111 (see...). Figure 3 The positioning groove 111 is configured to fit the protrusion 300 and accommodate at least a portion of the protrusion 300, so that the support platform 120 can be inserted into the protrusion 300 through the positioning groove 111 to achieve a detachable connection with the support base 110.

[0038] In this embodiment, the detachable connection between the support platform 120 and the support base 110 greatly enhances the flexibility and versatility of the vehicle maintenance lifting device 100. In other embodiments, the connection between the support platform 120 and the support base 110 can also be achieved through snap-fit ​​connections, bolt connections, or other connection methods.

[0039] In this embodiment, viewed from both the front and rear sides (a), the upper surface of the support platform 120 is arc-shaped (see...). Figure 12 The arc shape curves downwards from the middle. This arc design allows the support platform 120 to be placed more effectively and securely to the car tire (see...). Figure 10 This provides a good support platform for automobile maintenance. In other embodiments, the arc-shaped design is not limited to this; it can also be configured as a stepped shape with a lower center and higher sides, or any other shape that can achieve the effect of a lower center and higher sides (see [reference]). Figure 13The support platform 120 has a certain height, which allows it to lift the car to the required position during use, facilitating the maintenance, inspection, or other operations of the car, ensuring that operators can operate the car at a suitable height, and improving work efficiency and safety.

[0040] like Figure 2 As shown, four conical barrels 121 are recessed downward from the upper surface of the support platform 120. The radius of the conical barrels 121 gradually decreases from the upper surface to the lower surface. The conical barrels 121 can effectively collect various liquids generated during automobile maintenance and discharge them smoothly, thereby preventing liquids from accumulating on the support platform 120 and ensuring the smooth progress of maintenance work.

[0041] In this embodiment, both the front and rear sides a of the support platform 120 are recessed inward from the outer surface to form trapezoidal grooves 122. The trapezoidal grooves 122 penetrate the upper surface of the support platform 120 and terminate at the lower surface. The trapezoidal grooves 122 are approximately trapezoidal in shape, such as... Figure 1 As shown, the width of the trapezoidal groove 122 gradually decreases from the upper surface to the lower surface. The design of the trapezoidal groove 122, wider at the top and narrower at the bottom, makes the installation and disassembly of the support platform 120 and the support base 110 more convenient. When the support platform 120 and the support base 110 are in a plug-in fit, the protrusion 300 (see...) Figure 2 ) and positioning groove 111 (see Figure 3 The close fit and plug-in fixing method make the installation of the support platform 120 and the support base 110 convenient, efficient, and the connection stable and reliable. In other embodiments, the shape of the protrusion 300 can also be circular, polygonal, or other shapes.

[0042] The support platform 120 is also provided with a side groove 125, which penetrates the upper surface of the support platform 120 and the left (or right) side of the support platform 120, and connects to the conical barrel 121.

[0043] like Figure 1 As shown, in this embodiment, an X-shaped groove 123 is formed by recessing downwards from the upper surface of the support platform 120. The X-shaped groove 123 is configured such that each end connects to the conical barrel 121. The opening of the X-shaped groove 123 causes the upper surface of the support platform 120 to form multiple edges 303, which can increase the friction between the support platform 120 and the car tire, improve safety, prevent tire slippage, enhance vehicle support stability, and thus ensure the smooth progress of automobile maintenance work. Figure 4As shown, the X-shaped groove 123 has a triangular cross-section, and its width gradually decreases from the upper surface to the lower surface. When liquid is present during use, the X-shaped groove 123 connects to each of the conical barrels 121, guiding the generated liquid into each conical barrel 121. In other embodiments, to accommodate tires with different tread patterns, the X-shaped groove can also be Z-shaped, D-shaped, or other shapes that connect to each of the conical barrels 121.

[0044] like Figure 2 and Figure 3 As shown, a water collection tank 112 is recessed downwards from the upper surface of the support base 110 at the position corresponding to the conical barrel 121. The water collection tank 112 can efficiently collect various liquids generated during vehicle maintenance, preventing liquid accumulation in the work area, maintaining a clean and safe maintenance working environment, and ensuring the smooth progress of the maintenance process. A drain hole 124 is formed by perforating the bottom of the conical barrel 121, which can drain the liquid accumulated in the conical barrel 121. At the same time, a cross groove 113 is recessed downwards from the upper surface of the support base 110 at the position corresponding to the X-shaped groove 123. Each end of the cross groove 113 is connected to the water collection tank 112. The upper surface of the support base 110 is also recessed with a drain groove 114 and a connecting groove 301, with the two ends of the connecting groove 301 connecting the drain groove 114 and the water collection tank 112, respectively. The interconnection between the water collection tank 112, the cross tank 113, and the drainage tank 114 forms a complete drainage network. This interconnected structure can guide the liquid to flow in a preset direction, allowing the liquid to gather together in an orderly manner, thus preparing for subsequent drainage work.

[0045] like Figure 1 and Figure 2 As shown, side groove plates 126 are provided on both sides of the side groove 125, and the side groove plates 126 are connected to the conical barrel 121 and the support platform 120 respectively. This unique connection method, in which the side groove 125 is recessed in the support platform 120 to connect the conical barrel 121 and the support platform 120, results in side ridges 302 on the support platform 120 formed by the side groove 125. These side ridges 302 can play a role in strengthening the support, effectively improving the stability and load-bearing capacity of the overall structure. They can not only fix the position of the conical barrel 121 on the support platform 120, but also effectively distribute the pressure applied by the vehicle to the conical barrel 121 during vehicle maintenance, avoiding structural damage caused by excessive local stress, thereby improving the reliability and durability of the entire vehicle maintenance lifting device 100.

[0046] In this embodiment, by means of the left and right sides b of the support platform 120 (see...) Figure 11A perforation operation is performed to create access holes 127. Whether moving the support platform 120 or during the installation and disassembly of the device, maintenance personnel can easily apply force through these access holes 127 to achieve flexible movement and precise positioning of the support platform 120.

[0047] like Figure 2 and Figure 5 As shown, in this embodiment, a reinforcing rib 115 is provided on the lower surface of the support base 110 corresponding to the conical barrel 121, extending downwards from the bottom. The reinforcing rib 115 increases the load-bearing strength of the support base 110, effectively disperses pressure, avoids stress concentration, and ensures the stability and reliability of the overall structure. This layout effectively enhances the load-bearing capacity of the support base 110 in critical stress areas, preventing structural deformation or damage caused by excessive stress on the conical barrel 121. Furthermore, this layout does not interfere with the normal use and operation of the support platform 120, ensuring convenience and safety for maintenance personnel during operation. In other embodiments, in addition to providing the reinforcing rib 115, the structural strength of the support base 110 can also be increased by strengthening the wall thickness, adding support structures, etc.

[0048] Reference Figure 5 In this embodiment, the support base 110 is also provided with fixing holes 116, which penetrate the upper and lower surfaces of the support base 110. The fixing holes 116 can be used to fix the support base 110 to the ground or other supporting surfaces using bolts or screws. The design of the fixing holes 116 ensures the stability of the support base 110 in different application scenarios and facilitates flexible adjustment according to actual needs. Furthermore, the multiple fixing holes 116 provide various installation methods and angle options, further enhancing the applicability and flexibility of the support base 110. The support base 110 can also raise the height of the support platform 120 to meet the needs of different scenarios.

[0049] like Figure 2 and Figure 5 As shown, in this embodiment, the support platform 120 and the support base 110 are each provided with a plurality of reinforcing plate structures. A plurality of crisscrossing upper reinforcing plates 128 extend downward from the upper surface of the inner surface of the support platform 120, and a plurality of crisscrossing lower reinforcing plates 117 extend downward from the lower surface of the inner surface of the support base 110. The reinforcing plate structures enhance the load-bearing capacity of the support platform 120 and the support base 110, ensuring that the entire device remains stable and reliable when subjected to vehicle weight and various external forces.

[0050] Reference Figure 1In this embodiment, all edges 303 on the outer surfaces of the support platform 120 and the support base 110 are rounded. This design not only makes the support platform 120 more rounded and smooth in appearance, avoiding potential safety hazards from sharp edges, but also reduces damage to the surface of the support platform 120 caused by collisions or friction during use. At the same time, the rounded corners also make the support platform 120 easier to assemble or install with other components, improving overall assembly efficiency and aesthetics.

[0051] like Figure 6 As shown, this utility model also provides a tire repair combination pad 200, including a support base 110 and a support platform 120. The support base 110 is provided with a positioning groove 111 (see...). Figure 3 The support platform 120 is inserted and fixed to the support base 110. The support base 110 and the support platform 120 are connected by a positioning groove 111 (see...). Figure 3 The support platform 120 is installed by plugging in the protrusion 300. An arc-shaped surface 129 is recessed on the top of the support platform 120. Viewed from both the front and rear sides (a), the arc-shaped surface 129 curves downwards from the middle (see reference). Figure 12 The curved surface 129 is used to place the car tire (see...). Figure 10 The support base 110 can raise the height of the support platform 120 to meet the needs of different scenarios.

[0052] like Figure 6 As shown, the upper surface of the arc-shaped surface 129 is recessed downwards to form a friction groove. The friction groove includes a conical groove 1291 with a circular cross-section (see...). Figure 8 ) and a connecting groove 1292 with a triangular cross-section (see Figure 9 The circular cross-section design of the conical groove 1291 allows the support platform 120 to effectively distribute pressure when under stress, reducing localized wear and making the overall structure more robust and enhancing its resistance to damage. By effectively dispersing the pressure between different parts of the support platform 120 through the friction groove, the stability of the entire structure is greatly improved. This not only ensures the safety of the support platform 120 during single use but also ensures that it can consistently provide reliable support for the vehicle during long-term use.

[0053] Reference Figure 7In this embodiment, the connecting groove 1292 is further subdivided into a central connecting groove 1293 and an edge connecting groove 1294. Each end of the central connecting groove 1293 connects to the conical groove 1291, while the edge connecting groove 1294 penetrates the arc-shaped surface 129 and the left (or right) side surface of the support platform 120. The central connecting groove 1293 and the edge connecting groove 1294 form side ridges 302 on the arc-shaped surface 129. The side ridges 302 increase the structural strength of the support platform 120, improving its stability and load-bearing capacity. Furthermore, in other embodiments, the connecting groove 1292 can also adopt annular, rhomboid, or other shapes to meet diverse design requirements and application scenarios.

[0054] The vehicle repair lifting device 100 provided by this utility model exhibits several significant advantages in vehicle repair scenarios. A conical barrel 121, an X-shaped groove 123, and a side groove 125 are provided on the upper surface of the support platform 120. These structures effectively increase the friction between the vehicle tire and the upper surface of the support platform 120, thereby preventing tire slippage during vehicle repair operations and ensuring stable tire support during the repair process.

[0055] The support platform 120 is equipped with crisscrossing upper reinforcing plates 128, and the support base 110 is equipped with crisscrossing lower reinforcing plates 117. Together, they enhance the load-bearing capacity of the entire device. The protrusions 300 formed by trapezoidal grooves 122 on both sides of the support platform 120 fit tightly with the positioning grooves 111 of the support base 110, ensuring a stable connection between the support platform 120 and the support base 110. Furthermore, the side grooves 125 and the reinforcing ribs at the corresponding positions of the conical barrel 121 on the support base 110 effectively disperse pressure and prevent stress concentration. This not only improves the overall structural stability but also further enhances the load-bearing capacity, preventing damage to the device due to excessive localized stress.

[0056] Regarding liquid collection and drainage, the conical bucket 121 on the support platform 120 can collect liquids generated during automobile repair, preventing liquid accumulation on the support platform 120. A water collection trough 112 is provided on the support base 110 corresponding to the conical bucket 121, which can efficiently collect liquids, thereby maintaining a clean and safe repair environment. Furthermore, the drain hole 124 at the bottom of the conical bucket 121, the cross groove 113 of the support base 110, the drain trough 114, and the connecting groove 301 are interconnected, forming a complete drainage network that guides the orderly flow and convergence of liquids, facilitating subsequent drainage.
