Technical Field
[0001] This utility model relates to the field of automobile chassis support, specifically a chassis support device for testing new energy vehicles. Background Technology
[0002] Two-post lifts are a type of specialized mechanical lifting equipment commonly used in auto repair and maintenance shops. Two-post lifts are the main type of lift and are widely used in the repair and maintenance of small cars such as sedans. There are two types of two-post lifts: symmetrical and asymmetrical. In a symmetrical lift, the four arms are roughly the same length, which makes the center of gravity of the car located in the middle of the pillar. For the routine maintenance of vehicles such as pickup trucks and vans, this type of symmetrical lift may be the best choice.
[0003] In existing technologies, two-post lifts can support and raise the chassis of new energy vehicles, making it easier for employees to conduct comprehensive inspections of the vehicle's chassis, promptly identify and resolve chassis faults or hidden dangers, and prevent accidents. New energy vehicles are divided into pure electric vehicles, plug-in hybrid electric vehicles, range-extended hybrid electric vehicles, fuel cell electric vehicles, and hybrid electric vehicles. Among them, range-extended electric vehicles have an engine inside the vehicle, and the engine is located at the front of the vehicle, which makes the front of the vehicle heavier than the rear. When a two-post lift is used to lift the vehicle, the front of the vehicle lacks support, which can easily cause the vehicle to sway and tip over. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, range-extended electric vehicles have an engine inside the vehicle, and the engine is located at the front of the vehicle, which makes the front of the car heavier than the rear. When a two-post lift is used to lift the car, the front of the car lacks support, which can easily cause the car to sway and tip over. This utility model proposes a chassis support device for testing new energy vehicles.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a chassis support device for testing new energy vehicles, including a double-column lift, wherein a support mechanism is provided on one side of the double-column lift;
[0006] The support mechanism includes a first fixed plate, the bottom of which is fixedly connected to the top of the two-post lift. A motor is fixedly connected to the bottom of the first fixed plate, and a first threaded rod is fixedly connected to the surface of the output shaft of the motor. A second fixed plate is fixedly connected to one side of the two-post lift, and a limit rod is fixedly connected to the top of the second fixed plate. A first connecting strip is slidably connected to the surface of the limit rod, and a second connecting strip is threadedly connected to the surface of the first threaded rod. A first hollow groove is formed on the surface of the first hollow groove, and a second threaded rod is rotatably connected to the inner cavity of the first hollow groove. A connecting block is threadedly connected to the surface of the second threaded rod, and a support rod is fixedly connected to one side of the connecting block. A U-shaped slider is slidably connected to the surface of the second connecting strip, and the inner cavity of the U-shaped slider is fixedly connected to the top of the support rod.
[0007] Preferably, a rubber pad is provided at the top of the first connecting strip, and the bottom of the rubber pad is fixedly connected to the top of the support rod.
[0008] Preferably, the surface of the first threaded rod is provided with a second hollow groove, and a reinforcing rod is provided in the inner cavity of the second hollow groove. One side of the reinforcing rod is fixedly connected to one side of the two-post lift.
[0009] Preferably, a fixing block is provided at the top of the first threaded rod, and the inner cavity of the fixing block is fixedly connected to the surface of the motor's output shaft.
[0010] Preferably, a limiting block is provided on the surface of the second threaded rod, and one side of the limiting block is fixedly connected to one side of the first connecting strip.
[0011] Preferably, the inner cavity of the first connecting strip is provided with a third hollow groove, and a rotating block is rotatably connected to the inner cavity of the third hollow groove. One side of the rotating block is fixedly connected to one side of the second threaded rod.
[0012] Preferably, a limiting strip is fixedly connected to one side of the second connecting strip, and the height of the limiting strip is greater than the height of the second connecting strip.
[0013] The advantages of this utility model are:
[0014] This invention uses a two-post lift to support and raise a range-extended electric vehicle. The motor then rotates the first threaded rod, which in turn moves the second connecting bar, which in turn moves the support rod. Once the support rod has moved, it supports the bottom of the vehicle's front end, preventing the front from swaying or becoming unstable due to excessive weight after the vehicle is lifted. If the front of the vehicle is too long and the support rod is aligned with the front tire, the second threaded rod can be rotated first to move the connecting block inside the first hollow groove. When the connecting block moves, it simultaneously moves the support rod, allowing the support rod to move horizontally to avoid the front tires of the car. This ensures that the front of the car can continue to be supported smoothly without being obstructed by the tires. This achieves the effect of preventing the front of the car from swaying and becoming unstable due to excessive weight when the car is lifted by the two-pillar lift. This solves the problem that in range-extended electric vehicles, the engine is located in the front of the car, causing the front of the car to be heavier than the rear. When the two-pillar lift lifts the car, the lack of support for the front of the car can easily lead to swaying and tipping. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses a chassis support device for testing new energy vehicles. (Refer to...) Figure 1-3 A chassis support device for testing new energy vehicles includes a two-post lift 1, with a support mechanism 2 on one side of the two-post lift 1. The two-post lift 1 can support and lift range-extended new energy vehicles, thereby facilitating employees to test the vehicles.
[0024] The support mechanism 2 includes a first fixed plate 201, the bottom of which is fixedly connected to the top of the double-column lift 1. A motor 202 is fixedly connected to the bottom of the first fixed plate 201. A first threaded rod 203 is fixedly connected to the surface of the output shaft of the motor 202. A second fixed plate 204 is fixedly connected to one side of the double-column lift 1. A limit rod 205 is fixedly connected to the top of the second fixed plate 204. A first connecting strip 206 is slidably connected to the surface of the limit rod 205. A second connecting strip 207 is threadedly connected to the surface of the first threaded rod 203. A first hollow groove 209 is formed on the surface of the first connecting strip 206. A second threaded rod 210 is rotatably connected to the inner cavity of the first hollow groove 209. A connecting block 211 is threadedly connected to the surface of the second threaded rod 210. A support rod 208 is fixedly connected to one side of the connecting block 211. A U-shaped slider 212 is slidably connected to the surface of the second connecting strip 207. The inner cavity of the U-shaped slider 212 is fixedly connected to the top of the support rod 208.
[0025] The first fixing plate 201 can be used to connect the motor 202, allowing the motor 202 to be stably positioned on one side of the two-post lift 1. The motor 202 can drive the first threaded rod 203 to rotate, and the rotation of the first threaded rod 203 can drive the second connecting bar 207 to move. The second fixing plate 204 can be used to support the limiting rod 205, and the limiting rod 205 can be connected to the first connecting bar 206, allowing the first connecting bar 206 to slide on one side of the two-post lift 1. The support rod 208 is located between the first connecting bar 206 and the second connecting bar 207, and can limit the second connecting bar 207 through the first connecting bar 206, so that the second connecting bar 207 does not easily rotate together when the first threaded rod 203 rotates, but can instead move smoothly. The support rod 208 can be moved, and it can also be moved together with the second connecting bar 207. This allows the support rod 208 to support the front of the range-extended electric vehicle, so that the front of the vehicle is not prone to swaying or instability due to excessive weight after the vehicle is lifted by the dual-pillar lift 1. The second threaded rod 210 can be used to move the connecting block 211, and the connecting block 211 can move the support rod 208 together. This allows the support rod 208 to be adjusted in position by moving, so that it can be used for vehicles of different lengths and will not abut against the front wheels of the vehicle. The U-shaped slider 212 can connect the support rod 208 and the second connecting bar 207, and at the same time, it allows the support rod 208 to slide on one side of the second connecting bar 207.
[0026] Reference Figure 1 A rubber pad 3 is provided at the top of the first connecting strip 206. The bottom of the rubber pad 3 is fixedly connected to the top of the support rod 208. The rubber pad 3 has a large friction force, which makes the support rod 208 more stable when supporting the front of the car. In addition, the rubber pad 3 can also prevent the support rod 208 from damaging the chassis of the car.
[0027] Reference Figure 2 The surface of the first threaded rod 203 is provided with a second hollow groove 4. A reinforcing rod 5 is provided in the inner cavity of the second hollow groove 4. One side of the reinforcing rod 5 is fixedly connected to one side of the double-column lift 1. The reinforcing rod 5 can be placed inside the second hollow groove 4, so that the reinforcing rod 5 can reinforce the bottom of the first threaded rod 203 through the second hollow groove 4, making it less likely for the first threaded rod 203 to wobble and become unstable under the motor 202.
[0028] Reference Figure 2 A fixing block 6 is provided at the top of the first threaded rod 203. The inner cavity of the fixing block 6 is fixedly connected to the output shaft surface of the motor 202. The fixing block 6 can limit the second connecting bar 207, so that when the first threaded rod 203 drives the second connecting bar 207 to move, the second connecting bar 207 is unlikely to touch the motor 202, thus preventing damage to the motor 202.
[0029] Reference Figure 3 The surface of the second threaded rod 210 is provided with a limiting block 7. One side of the limiting block 7 is fixedly connected to one side of the first connecting strip 206. The limiting block 7 can limit the second threaded rod 210, making the second threaded rod 210 more stable inside the first hollow groove 209 and less prone to displacement and shaking.
[0030] Reference Figure 4 The inner cavity of the first connecting bar 206 is provided with a third hollow groove 8. A rotating block 9 is rotatably connected to the inner cavity of the third hollow groove 8. One side of the rotating block 9 is fixedly connected to one side of the second threaded rod 210. The third hollow groove 8 and the rotating block 9 are both T-shaped, so that the third hollow groove 8 can limit the rotating block 9, making it difficult for the rotating block 9 to move. The rotating block 9 can also limit the second threaded rod 210, making it difficult for the second threaded rod 210 to come out of the interior of the first hollow groove 209.
[0031] Reference Figure 1 A limiting strip 10 is fixedly connected to one side of the second connecting strip 207. The height of the limiting strip 10 is greater than the height of the second connecting strip 207. The limiting strip 10 can limit the U-shaped slider 212 and the support rod 208, so that the U-shaped slider 212 and the support rod 208 are less likely to detach from the second connecting strip 207.
[0032] Working Principle: When using this device, the dual-post lift 1 is first used to lift and raise the range-extended electric vehicle, facilitating employee inspection of the vehicle's chassis. After lifting, the motor 202 is started to rotate the first threaded rod 203. The first threaded rod 203 drives the second connecting bar 207 to move. Simultaneously, the second connecting bar 207 drives the support rod 208 to move via the U-shaped slider 212. The support rod 208 then drives the first connecting bar 206 to slide on the surface of the limiting rod 205 via the connecting block 211 and the second threaded rod 210. After the support rod 208 moves, it supports the bottom of the vehicle's front end, allowing the vehicle to be lifted and raised by the dual-post lift 1. The front of the car is less likely to wobble or become unstable due to excessive weight. When the front of the car is too long and the support rod 208 is aligned with the front tire, the second threaded rod 210 can be rotated first to move the connecting block 211 inside the first hollow groove 209. The connecting block 211 will simultaneously move the support rod 208 together, allowing the support rod 208 to move horizontally to avoid the front tire of the car, thus continuing to support the front of the car smoothly without being blocked by the tire. This solves the problem that the front of the car is heavier than the rear of the car because the engine is located in the front of the range-extended electric vehicle, and the lack of support for the front of the car when the two-post lift 1 lifts the car can easily cause the car to wobble and tip over.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
