[0035] In Formula racing, vehicle maintenance, inspection, and tire changes are crucial aspects, as their efficiency and convenience directly impact pit stop time and race results. Take the M21-F4 Formula car as an example: while its design prioritizes high-speed performance and safety, traditional support methods present numerous inconveniences when the car is parked for maintenance.

[0036] Currently, M21-F4 race cars are typically supported by jacks or manually when parked for maintenance. Using jacks requires operators to spend time placing and adjusting them, and the stability of the jacks must be ensured during operation to prevent the car from slipping and causing personal injury or vehicle damage. Manual support, on the other hand, requires multiple workers to work together, which is not only time-consuming and labor-intensive, but also difficult to complete quickly in emergency situations.

[0037] To solve this technical problem, this utility model proposes a racing car lifting and lowering device 1.

[0038] Please see Figures 1 to 5 In one embodiment of this utility model, the racing car landing device 1 includes a main frame 10, a support frame 20, and a fixing frame. The main frame 10 includes a support body 11 and a wheel frame 12, with rollers 40 respectively provided at both ends of the wheel frame 12. The support frame 20 is installed on the wheel frame 12, and the support frame 20 and the support body 11 are set at an acute angle and intersect on the wheel frame 12. The support frame 20 is used to support the vehicle. The fixing frame is used to connect at least the support body 11 and the support frame 20. This satisfies the need for immediate support of the racing car, improves operating efficiency, and saves operating time.

[0039] In the technical solution of this utility model, the support frame 20 and the bracket body 11 are set at an acute angle, and the bracket body 11 and the support frame 20 are connected by a fixing frame. The triangular structure formed can ensure the stability of the support frame 20 on the main frame 10. Thus, the support frame 20 supports any position of the bottom of the race car. According to the lever principle, with the axis of the roller 40 as the rotation center, a force is applied to the end of the bracket body 11 away from the wheel frame 12. Thus, the support frame 20 can reliably lift the race car off the ground or land it, so as to facilitate maintenance work on the bottom of the race car. It is easy to operate and reliably improves operating efficiency and saves operating time.

[0040] It should be noted that the support frame 20 and the bracket body 11 are set at an acute angle. Compared to a right angle, this arrangement allows for stronger vertical support of the race car landing gear 1, more even stress distribution, and thus improved overall strength and durability. It also allows for a more compact design of the support rod and bracket body 11, better adapting to the support of the race car within limited space. Furthermore, it allows for the use of thinner or lighter tubular or rod-like structures while meeting the same support requirements. The support position of the support frame 20 can be any location on the bottom of the race car, specifically as follows: Figure 5 The rear end of the car shown is at the bottom.

[0041] Specifically, the race car landing gear 1 is made of stainless steel, which ensures high structural strength and makes the structure more robust, facilitating the support of M21-F4 Formula race cars weighing no more than 600KG and ensuring operational safety. The main frame 10, support frame 20, and fixing frame can be made of tubular, rod-like, or more complex combined structures. When the main frame 10, support frame 20, and fixing frame are configured as tubular structures, they can be made of round tubes, thus reducing the overall weight of the race car landing gear 1.

[0042] The roller 40 is configured as a nylon wheel. Nylon material has excellent wear resistance, can maintain good performance during long-term use, reduce wear and replacement frequency, and is also lightweight, which helps to reduce the overall weight of the racing car landing device 1. It also makes it easy to push and pull the racing car landing device 1, thereby improving the movement efficiency of the racing car landing device 1.

[0043] Optionally, in an embodiment of this utility model, the included angle between the bracket body 11 and the support frame 20 is a1, 60°≤a1≤70°. By using the acute angle between the bracket body 11 and the support frame 20, the center of gravity is low, which allows for a more uniform distribution of force among the support frame 20, the bracket body 11, and the fixed frame. That is, when the race car is supported above the support frame 20, its gravity will be transmitted along the support frame 20 and the fixed frame. Due to the existence of the acute angle, there are more directions of force decomposition, which can effectively disperse stress and reduce the stress concentration of the local support. Furthermore, setting the included angle between the bracket body 11 and the support frame 20 between 60° and ≤70°, the smaller included angle allows the support frame 20 to have a shorter moment arm when bearing vertical loads, thereby reducing the bending deformation of the support frame 20. It also allows the free end of the support frame 20 to be close to the bracket body 11, so as to adapt to use in environments with limited space.

[0044] At this point, the included angle between the support body 11 and the fixed frame can be 90°, slightly greater than 90°, or slightly less than 90°. This can further optimize the load distribution, reduce local stress concentration on the support frame 20, improve the load-bearing capacity of the racing car landing device 1, and simultaneously improve the stability of the entire triangular structure, reducing the bending deformation of the support frame 20. Specifically, the included angle α1 between the support body 11 and the support frame 20 can take values ​​including but not limited to 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, and 70°.

[0045] Please see Figures 1 to 2 In an embodiment of this utility model, the bracket body 11 includes a first connecting segment 111 and a second connecting segment 112. One end of the first connecting segment 111 is connected to the wheel frame 12, and the other end is bent and connected to the second connecting segment 112. That is, the second connecting segment 112 can be bent from the end of the first connecting segment 111 away from the wheel frame 12 to improve the structural strength of the bracket body 11, or the first connecting segment 111 and the second connecting segment 112 can be fixed into a whole by welding or other means.

[0046] The bending design of the first connecting segment 111 and the second connecting segment 112 allows the operator to apply force to the support body 11 in a more effortless manner, rotating it around the roller 40 as the center of rotation to lift one side of the race car. Specifically, the first connecting segment 111 extends horizontally along the length of the support body 11; and / or, the second connecting segment 112 is inclined upwards in a direction away from the first connecting segment 111, thus utilizing the lever principle to achieve effort reduction within the support body 11.

[0047] Specifically, in an embodiment of this utility model, the included angle between the first connecting segment 111 and the second connecting segment 112 is a2, where 155°≤a2≤165°. This allows for increasing the included angle a2, thereby increasing the length of the power arm and decreasing the length of the resistance arm, thus making it easier to achieve effort savings. The specific values ​​of the included angle a2 between the first connecting segment 111 and the second connecting segment 112 include, but are not limited to, 155°, 156°, 157°, 158°, 159°, 160°, 161°, 162°, 163°, 164°, and 165°.

[0048] Please see Figure 1 In an embodiment of this utility model, the bracket body 11 further includes a gripping section 113, which is vertically connected to the end of the second connecting section 112 away from the wheel frame 12. This allows the operator to grip the gripping section 113 and rotate the main frame 10 around the axis of the roller 40, thereby lifting one side of the race car via the support frame 20. The gripping section 113 and the second connecting section 112 can be fixed into a whole by welding or other methods.

[0049] Please see Figure 1 , Figures 3 to 4 In an embodiment of this utility model, the end of the support frame 20 away from the main frame 10 is provided with an abutment structure 21 for supporting the vehicle. This abutment structure 21 can be a support rod or a support platform. The abutment structure 21 and the support frame 20 body are fixed together as a whole through integral molding, welding, or other methods to ensure overall structural stability and strength. The abutment structure 21 can extend horizontally, providing a large support area with the bottom of the race car, thereby achieving reliable support for the race car. A reinforcing structure can be provided between the abutment structure 21 and the support frame 20 body.

[0050] Please see Figures 1 to 4 In this embodiment of the present invention, the fixing frame is configured as a first fixing frame 31 and a second fixing frame 32. The first fixing frame 31 connects the support frame 20 and the bracket body 11, and the second fixing frame 32 connects the support frame 20 and the wheel frame 12. Two fixing frames are symmetrically arranged on both sides of the support frame 20. Thus, the first fixing frame 31, the support frame 20, and the bracket body 11 form a triangular structure, and the second fixing frame 32, the support frame 20, and the wheel frame 12 form a triangular structure. Each triangular structure supports each other on the periphery of the support frame 20, which greatly enhances the stability of the overall structure and further enhances the bending and torsional resistance of the racing car landing device 1 in the vertical direction. It provides reliable support for the support frame 20 to support the racing car, helps to disperse the force through multiple paths, reduces the force concentration of each bracket, and even if one bracket is damaged or fails, other triangular structures can still provide support. This redundant design improves the reliability and safety of the overall structure.

[0051] Please see Figure 4 In an embodiment of this utility model, the support frame 20 is perpendicular to the wheel frame 12, and / or the angle between the second fixing frame 32 and the wheel frame 12 is equal to the angle between the second fixing frame 32 and the support frame 20. Thus, the support frame 20, the second fixing frame 32, and the wheel frame 12 form an isosceles right-angle structure. Since there are two second fixing frames 32 symmetrically arranged on both sides of the support frame 20, the force on the wheel frame 12 on both sides of the support frame 20 is equal, which helps to reduce local stress concentration, improve the stability of the overall structure, and ensure the safety of the structure.

[0052] Please see Figure 3 and Figure 4 In an embodiment of this utility model, the race car landing device 1 has a centerline extending along its length. The race car landing device 1 is symmetrically arranged about the centerline. This arrangement facilitates the design and manufacture of the race car landing device 1 and allows the weight of the race car acting on the support frame 20 to be evenly distributed to both sides of the centerline. This reduces deformation or damage caused by local stress concentration, improves the structural stability of the race car landing device 1, and also improves the redundancy and reliability of the race car landing device 1. That is, when the structure on one side is damaged, the other side can still maintain the stability of the structure and ensure the support of the race car.

[0053] Based on this, in the embodiments of this utility model, the length of the bracket body 11 is L, 1548cm≤L≤1552cm; and / or, the width of the wheel frame 12 is K1, 470cm≤K1≤474cm; the vertical height of the support frame 20 is H, 308cm≤H≤312cm; and / or, the width of the grip section 113 is K2, 398cm≤K2≤402cm. By limiting the above parameters, labor-saving operation can be achieved to a certain extent, and the racing car lifting device 1 can be suitable for single-person operation.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
