Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle maintenance lift and racing car components. Background Technology

[0002] Vehicle maintenance involves using technical means to troubleshoot malfunctions, identify the causes of the malfunctions, and take measures to eliminate the malfunctions and restore the vehicle to a certain performance and safety standard.

[0003] When a vehicle is being inspected, a lifting platform is usually used to lift it up, making it easier for repair personnel to perform repairs from underneath the car. However, the existing easy-to-store lifting platforms have weak support stability and are prone to accidents. Utility Model Content

[0004] The main purpose of this utility model is to provide a vehicle maintenance lift, which aims to improve the support stability of a vehicle maintenance lift that is easy to store.

[0005] To achieve the above objectives, the present invention provides a vehicle maintenance lifting frame, which includes at least one support unit, the support unit comprising:

[0006] Support crossbar;

[0007] The first support leg is connected at its upper end to the support crossbar;

[0008] The second support leg has its upper end rotatably connected to the upper end of the first support leg or the support crossbar; and

[0009] A limiting telescopic component is provided, with its two ends connected to the first support leg and the second support leg, respectively. When the support unit is in the extended state, the lower ends of the first support leg and the second support leg are far apart. When the support unit is in the retracted state, the lower ends of the first support leg and the second support leg are close together.

[0010] In one embodiment, at least two limiting telescopic members are provided, with at least one limiting telescopic member provided on each side of the extension direction of the supporting crossbar.

[0011] In one embodiment, the limiting telescopic member includes two hinge rods that are rotatably connected to each other, and the ends of the two hinge rods that are far apart from each other are respectively rotatably connected to the first support leg or the second support leg.

[0012] In one embodiment, the upper end of the first support leg is provided with a mounting rod, the mounting rod having a mounting end extending laterally relative to the first support leg, the upper end of the second support leg being rotatably connected to the mounting end, and when the support unit is in the unfolded state, the upper end of the second support leg abuts against the support crossbar.

[0013] In one embodiment, the first support leg and the second support leg each include a connecting rod and two support rods, with the two support rods respectively disposed at both ends of the connecting rod. The support rod of the first support leg is connected to the support crossbar, and the support rod of the second support leg is rotatably connected to the support rod of the first support leg or the support crossbar.

[0014] In one embodiment, the support crossbar and / or the support rod and / or the connecting rod are made of stainless steel.

[0015] In one embodiment, the connecting rod is welded to the support rod.

[0016] In one embodiment, the support crossbar and / or the support rod and / or the connecting rod are arranged in the form of a rectangular tube.

[0017] The vehicle maintenance lift also includes a base, and multiple support units are provided. In each support unit, at least one of the first support leg and the second support leg is hinged to the base.

[0018] This utility model also proposes a racing car component, including the aforementioned vehicle maintenance lift, wherein the vehicle maintenance lift includes two of the aforementioned support units, and the height of the support unit used to support the front side of the racing car is greater than the height of the support unit used to support the rear side of the racing car.

[0019] This utility model's technical solution connects the upper end of the first support leg to the support crossbar, and rotatably connects the upper end of the second support leg to the upper end of the first support leg or the support strut. Then, it uses a limiting telescopic member to connect the first and second support legs at both ends. This allows the vehicle maintenance lift to rotate and open the second support leg during use, moving the lower ends of the first and second support legs apart. When the limiting telescopic member is extended to its maximum length, it limits the maximum opening angle of the two support legs, ensuring that the first and second support legs do not over-open due to uneven force or external impact, preventing the support unit from disintegrating and maintaining the overall structural stability of the support unit. Furthermore, during use, if one side of the support unit is subjected to a large lateral force, it is prone to tipping over. The presence of the limiting telescopic member increases the support unit's anti-tipping capability; it provides a reverse support force to offset part of the lateral force, making the support unit less likely to tip over when subjected to external forces, ensuring safe use. Secondly, the support unit forms a triangular prism between the support crossbar, the limiting telescopic component, and the first and second support legs. This triangular structure enhances the stability of the support unit, thus improving the stability of the vehicle maintenance lift and providing stable support for the vehicle. When the support unit is not in use, the second support leg can be rotated, causing the lower ends of the first and second support legs to approach each other. This brings the sides of the first and second support legs furthest from the support crossbar closer together. At this time, the limiting telescopic component also retracts under the action of the first and second support legs, reducing the volume of the support unit and facilitating its storage, which in turn facilitates the storage of the vehicle maintenance lift. Therefore, this invention improves the stability of the vehicle maintenance lift while also making it easier to store. Attached Figure Description

[0032] Vehicle maintenance involves using technical means to troubleshoot malfunctions, identify the causes of the malfunctions, and take measures to eliminate the malfunctions and restore the vehicle to a certain performance and safety standard.

[0033] When a vehicle is being inspected, a lifting platform is usually used to lift it up, making it easier for repair personnel to perform repairs from underneath the car. However, the existing easy-to-store lifting platforms have weak support stability and are prone to accidents.

[0034] This utility model proposes a vehicle maintenance lifting frame 10.

[0035] It should be noted that the vehicle inspection lift 10 provided in this solution is applicable, but not limited to, to the inspection of racing cars, family cars, sports cars, and other models.

[0036] Reference Figure 3 and Figure 4 In one embodiment of this utility model, the vehicle maintenance lift 10 includes at least one support unit 100. The support unit 100 includes a support crossbar 110, a first support leg 121, a second support leg 122, and a limiting telescopic member 130. The upper end of the first support leg 121 is connected to the support crossbar 110. The upper end of the second support leg 122 is rotatably connected to the upper end of the first support leg 121 or the support crossbar 110. The first support leg 121 and the second support leg 122 are respectively connected at both ends of the limiting telescopic member 130. When the support unit 100 is in the unfolded state, the lower ends of the first support leg 121 and the second support leg 122 are far apart. When the support unit 100 is in the retracted state, the lower ends of the first support leg 121 and the second support leg 122 are close together.

[0037] This utility model's technical solution connects the upper end of the first support leg 121 to the support crossbar 110, and rotatably connects the upper end of the second support leg 122 to the upper end of the first support leg 121 or the support strut. The first support leg 121 and the second support leg 122 are then connected at both ends by a limiting telescopic member 130. This allows the vehicle maintenance lift 10 to rotate and open the second support leg 122 during use, distancing the lower ends of the first support leg 121 and the second support leg 122. When the limiting telescopic member 130 extends to its maximum length, it limits the maximum opening angle of the two support legs, ensuring that the first and second support legs 121 and 122 do not over-open due to uneven force or external impact, preventing the support unit 100 from collapsing and maintaining the overall structural stability of the support unit 100. Furthermore, during use, if one side of the support unit 100 is subjected to a large lateral force, it is prone to tipping over. The presence of the limiting telescopic member 130 increases the anti-rollover capability of the support unit 100. It can provide a reverse support force to offset part of the lateral force, making the support unit 100 less likely to tip over when subjected to external forces, thus ensuring safety during use. Secondly, the support unit 100 forms a triangular prism between the support crossbar 110, the limiting telescopic member 130, the first support leg 121, and the second support leg 122. This utilizes the stability of the triangular structure to enhance the stability of the support unit 100, that is, to enhance the stability of the vehicle maintenance lift 10, thereby providing stable support for the vehicle. When the support unit 100 is not in use, the second support leg 122 can be rotated so that the lower ends of the first support leg 121 and the second support leg 122 come together. That is, the sides of the first support leg 121 and the second support leg 122 away from the support crossbar 110 move closer to each other. At this time, the limiting telescopic member 130 will also retract under the action of the first support leg 121 and the second support leg 122. This can reduce the volume of the support unit 100 and facilitate the storage of the support unit 100, which is also convenient for storing the vehicle maintenance lift 10. It can be seen that the technical solution of this utility model can improve the stability of the vehicle maintenance lift 10 while facilitating the storage of the vehicle maintenance lift 10.

[0038] Secondly, since the support unit 100 of this solution can be unfolded or retracted simply by pulling or pushing the first support leg 121 and / or the second support leg 122, without any other extra actions, the proposed vehicle maintenance lift 10 is easy to operate, can improve the efficiency of the support unit 100 when unfolding or retracting, and save operation time.

[0039] Optionally, in one embodiment, at least two limiting telescopic members 130 are provided, with at least one limiting telescopic member 130 provided on each side of the extending direction of the supporting crossbar 110; that is, one limiting telescopic member 130 connected to the second supporting leg 122 is provided on each side of the lateral direction of the first supporting leg 121, which is beneficial to improving the support strength of the two supporting legs, and thus beneficial to improving the support stability of the vehicle maintenance lifting frame 10.

[0040] Furthermore, in one embodiment, at least two limiting telescopic members 130 are provided at intervals along the height direction of the first support leg 121; this is beneficial to improving the support strength of the two support legs, and thus beneficial to improving the support stability of the vehicle maintenance lift 10.

[0041] In one embodiment, the limiting telescopic member 130 includes two hinge rods 131 rotatably connected to each other. The ends of the two hinge rods 131 that are far apart from each other are rotatably connected to the first support leg 121 or the second support leg 122, respectively. That is, the end of one hinge rod 131 that is far from the other hinge rod 131 is rotatably connected to the first support leg 121, and the end of the other hinge rod 131 that is far from one hinge rod 131 is rotatably connected to the second support leg 122. It can be understood that the hinge rods 131 can precisely limit the maximum opening angle between the first support leg 121 and the second support leg 122, ensuring that the support unit 100 maintains a stable structure during use. The hinge rods 131 can also evenly distribute the force received onto the first support leg 121 and the second support leg 122, avoiding excessive local force that could cause deformation or damage to the first support leg 121 and / or the second support leg 122. Of course, this solution is not limited to this; in other embodiments, the limiting telescopic member 130 can also be configured as a limiting rope.

[0042] Optionally, in this embodiment, the upper end of the first support leg 121 is provided with a mounting rod 140, the mounting rod 140 having a mounting end extending laterally relative to the first support leg 121, and the upper end of the second support leg 122 being rotatably connected to the mounting end. When the support unit 100 is in the unfolded state, the upper end of the second support leg 122 abuts against the support crossbar 110. It can be understood that when the support unit 100 is in the retracted state, the second support leg 122 is separated from the support crossbar 110, and the first support leg 121 and the second support leg 122 are in contact. When the support unit 100 is in the unfolded state, the upper end of the second support leg 122 abuts against the support crossbar 110. The support crossbar 110, the limiting telescopic member 130, and the first and second support legs 121 form a triangular prism, thereby utilizing the stability of the triangular structure to improve the stability of the support unit 100. At this time, the mounting rod 140 can also limit the maximum opening angle between the first and second support legs 121 and 122, thereby ensuring that the support unit 100 maintains a stable structure during use. Of course, this solution is not limited to this. In other embodiments, the mounting rod 140 may not be provided, and the upper end of the second support leg 122 may be rotatably connected to the support crossbar 110.

[0043] Optionally, in one embodiment, the first support leg 121 and the second support leg 122 each include a connecting rod 12a and two support rods 12b, with the two support rods 12b respectively disposed at both ends of the connecting rod 12a. The support rods 12b of the first support leg 121 are connected to the support crossbar 110, and the support rods 12b of the second support leg 122 are rotatably connected to the support rods 12b of the first support leg 121 or the support crossbar 110. This ensures the strength of the first support leg 121 and the second support leg 122 while reducing their weight. Of course, this solution is not limited to this; in other embodiments, the first support leg 121 and the second support leg 122 can also be configured as support plates.

[0044] Furthermore, the connecting rod 12a is located on the side of the two support rods 12b away from the support crossbar 110, which can better improve the strength of the support leg. Of course, this solution is not limited to this. In other embodiments, the connecting rod 12a is located in the middle of the two support rods 12b.

[0045] In one embodiment, the support crossbar 110 and / or the support rod 12b and / or the connecting rod 12a are made of stainless steel. This is because stainless steel has high strength and can withstand large external forces without deformation or breakage. In the application scenarios of the support crossbar 110, support rod 12b, and connecting rod 12a, whether bearing the weight of the vehicle or coping with external collisions, compression, or other forces, stainless steel can provide reliable support and connection. At the same time, it also has good toughness, and is not prone to brittle fracture when subjected to impact or vibration, ensuring the stability and safety of the support unit 100. Of course, this solution is not limited to this; in other embodiments, the support crossbar 110 and / or the support rod 12b and / or the connecting rod 12a can also be made of iron.

[0046] In one embodiment, the connecting rod 12a and the support rod 12b are welded. It is understood that after welding, the metal at the weld joint forms a continuous whole with the base material, and its connection strength often reaches or even exceeds the strength of the base material itself. The welded structure has high rigidity and is not easily deformed when subjected to external forces. Therefore, welding is used to connect the connecting rod 12a and the support rod 12b, which can improve the connection strength between the connecting rod 12a and the support rod 12b. Of course, this solution is not limited to this; in other embodiments, the connecting rod 12a and the support rod 12b can also be injection molded as a single piece.

[0047] In one embodiment, the support crossbar 110 and / or the support rod 12b and / or the connecting rod 12a are arranged in the form of a rectangular tube.

[0048] Optionally, in one embodiment, the support crossbar 110 is configured as a rectangular tube. It is understood that the flat upper surface of the rectangular tube provides a stable small platform that can stably support the vehicle's bottom frame, reducing the likelihood of the vehicle sliding relative to the support unit 100. When subjected to vertically downward pressure, the rectangular tube's cross-sectional shape provides better bending resistance than an equivalent circular tube, making the support crossbar 110 less prone to deformation. Rectangular tubes are generally superior to circular tubes in resisting torsion (torque). When the support unit 100 may be subjected to lateral forces or uneven loads, the rectangular tube support crossbar 110 can better help maintain the overall shape of the support unit 100, preventing twisting and thus improving overall stability. Secondly, configuring the support crossbar 110 as a tube reduces its weight, thereby reducing the weight of the support unit 100. Of course, this solution is not limited to this; in other embodiments, the support crossbar 110 can also be configured as a circular tube, with the top surface of the circular tube and the position abutting against the second support leg 122 configured as a support plane.

[0049] Optionally, in one embodiment, the support rod 12b and / or the connecting rod 12a are arranged in the form of a rectangular tube; this is because, with the same amount of steel, a rectangular tube (especially a square tube) has a larger section modulus, meaning it can withstand greater weight without bending deformation. This gives the support unit 100, produced by the support rod 12b and / or the connecting rod 12a, which are made of rectangular tubes, the following advantages: higher rated load: able to safely support heavier users and their tools and materials; longer service life: less prone to deformation due to fatigue after long-term use, resulting in a more durable structure. Of course, this solution is not limited to this; in other embodiments, the support rod 12b and / or the connecting rod 12a may also be arranged in the form of a circular tube.

[0050] Reference Figure 2 Optionally, in one embodiment, the vehicle maintenance lift 10 further includes a base 150. Multiple support units 100 are provided. In each support unit 100, at least one of the first support leg 121 and the second support leg 233 is hinged to the base 200. It can be understood that in each support unit 100, at least one of the first support leg 121 and the second support leg 122 is hinged to the base 200. That is, in this solution, each support unit 100 is hinged to the base 200, which prevents the support unit 100 from sliding sideways when supporting the vehicle, thereby increasing the stability of the vehicle maintenance lift 10.

[0051] Reference Figure 1 and Figure 2 This utility model also proposes a racing car component, which includes a vehicle maintenance lift 10. The specific structure of the vehicle maintenance lift 10 is as described in the above embodiments. Since this racing car component adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0052] Optionally, the vehicle maintenance lift 10 includes two support units 100. The height of the support unit 100 supporting the front side of the race car is greater than the height of the support unit 100 supporting the rear side of the race car. It can be understood that the front chassis of the race car is higher than the rear chassis. In this solution, the height of the support unit 100 supporting the front side of the race car is greater than the height of the support unit 100 supporting the rear side of the race car. This allows the supported race car to be level or nearly level, which reduces the probability of the race car slipping off the vehicle maintenance lift 10.

[0053] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
