Description

Technical Field

[0001] This utility model relates to the field of automotive calibration and testing technology, specifically a continuously adjustable slope test device for automotive calibration and testing. Background Technology

[0002] During the research and development testing of automobiles, various slope tests and trials are conducted to simulate actual road conditions and to perform related performance tests and calibrations.

[0003] However, the current methods employed fall into two categories. One involves pouring pavement with varying slopes at the test site or fabricating specialized slope test benches for different slopes. These methods are space-consuming, costly to manufacture, and generally limited to fixed locations. They also cannot address the needs of special slopes and are inflexible in their use. The other method involves adjusting the vehicle's tilt angle using jacks or manual hoists. However, this method requires manual operation, is time-consuming and labor-intensive, and carries certain risks. Furthermore, both of these methods are difficult to perform within high and low temperature environmental chambers. Utility Model Content

[0004] The purpose of this invention is to provide a continuously adjustable slope test device for automobile calibration testing, so as to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuously adjustable slope test device for automobile calibration testing, comprising a first frame and a second frame, the first frame and the second frame having the same structure and being fixed together by bolts, both the first frame and the second frame including a base, a ramp plate installed at one end of the base, a central platform installed in the middle of the base, and lifting platforms installed at both ends of the base on the central platform via support frames, the support frames being equipped with hydraulic rods for driving the lifting platforms to rise and fall, and a stopper installed on the top of the lifting platform.

[0006] Preferably, the support frame includes two parallel first support rods and two parallel second support rods. The first support rods and the second support rods are connected by pins. One end of each of the two first support rods is slidably connected to the base via a first connecting rod, and the other end of each of the two first support rods is connected to the lifting platform via pins. One end of each of the two second support rods is slidably connected to the lifting platform via a second connecting rod, and the other end of each of the two second support rods is connected to the base via pins.

[0007] Preferably, the base includes a base body, on which a connecting seat for connecting to the second support rod is provided, and the base body has a guide groove that mates with the end of the first connecting rod.

[0008] Preferably, the bottom of the lifting platform is provided with a connecting seat that connects to the first support rod.

[0009] Preferably, the inner surface of the stopper is an arc-shaped concave structure, and the stopper is fixed to the lifting platform by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The first and second frames are joined together and secured with bolts to prevent movement during lifting. Hydraulic lines are connected to external hydraulic cylinders; only after this connection can the vehicle be moved to the platform. The platform is divided into two sets for easy assembly, disassembly, and transportation.

[0012] The central platform is placed between the two lifting platforms, and the ramp is placed at one end of the frame to facilitate the movement of vehicles onto the lifting platform. Two small ramps facilitate the movement of cars onto the frame, and the small platform is placed between the two lifting platforms to facilitate vehicle movement. This effectively reduces the size of the lifting platform, lowers costs, and also reduces interference between the lifting platform and the vehicle chassis during the lifting process.

[0013] Move the vehicle onto the lifting platform. At this point, the platform and ramp can be removed, or the vehicle can be left in place and the stopper can be fixed to the fixed holes on the lifting platform with bolts to prevent the vehicle from sliding. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0022] Please see Figure 1-3 In this embodiment of the present invention, a continuously adjustable slope testing device for automobile calibration testing includes a first frame 1, a second frame 2, and a control device 3. The first frame 1 and the second frame 2 have identical structures and are fixed together by bolts. The frames provide support, and the two frames can be used separately for easy movement and transportation, or they can be fixed together by bolts to prevent displacement caused by slope changes when used simultaneously. Both the first frame 1 and the second frame 2 include a base 11, and a ramp 16 is installed at one end of the base 11. The ramp 16 is placed in front of the frame, and the platform is placed between two lifting platforms to facilitate the movement of the vehicle onto the frame. A central platform 12 is installed in the middle of the base 11, and both ends of the base 11 at the central platform 12 are supported by support frames 1. 4. A lifting platform 13 is installed (divided into four lifting platforms, which can be lifted individually or in multiples, and can achieve forward tilting, backward tilting, left tilting, right tilting, and various comprehensive slope conditions). The support frame 14 is equipped with a hydraulic rod 15 that drives the lifting platform 13 to lift. The hydraulic device can achieve stepless lifting, allowing the vehicle to tilt at any angle within the platform's lifting height, and has high stability. A stopper 17 is installed on the top of the lifting platform 13. The inner side of the stopper 17 has an arc-shaped concave structure, and the stopper 17 is fixed to the lifting platform 13 by bolts. Each of the four lifting platforms has a stopper 17 to prevent the vehicle from sliding during slope changes, increasing stability and safety. The addition of stoppers can stabilize the vehicle on the platform and prevent the vehicle from sliding after tilting. The surface of the platform also has anti-slip textures.

[0023] like Figure 2 , 4 5; The support frame 14 includes two parallel first support rods 141 and two parallel second support rods 142. The first support rods 141 and the second support rods 142 are connected by pins. One end of each of the two first support rods 141 is slidably connected to the base 11 via a first connecting rod 143, and the other end of each of the two first support rods 141 is connected to the lifting platform 13 via pins (the two ends of the first support rods 141 are respectively connected by rotation and sliding connections). One end of each of the two second support rods 142 is slidably connected to the lifting platform 13 via a second connecting rod 144, and the other end of each of the two second support rods 142 is connected to the base 11 via pins (the two ends of the second support rods 142 are respectively connected by rotation and sliding connections). The base 11 includes a base body 111. The base body 111 is provided with a connecting seat 113 connected to the second support rods 142. The base body 111 has a guide groove 112 that mates with the end of the first connecting rod 143. The bottom of the lifting platform 13 is provided with a connecting seat 113 connected to the first support rods 141. Scissor lift platforms, with their hydraulic rods moving in a manner different from gear-type mechanical structures, can achieve stepless lifting and offer greater stability.

[0024] Control device: The lifting and lowering of any single or multiple lifting platforms can be controlled by buttons. Bluetooth functionality has been added, allowing for remote use via remote control for increased convenience.

[0025] External hydraulic cylinder: The hydraulic cylinder is placed outside the hydraulic platform and installed together with the control device to ensure normal operation in high and low temperature environments. Extended hydraulic lines: The hydraulic lines are extended to facilitate placement of the test bench in the high and low temperature chamber and connection to the external hydraulic cylinder, keeping the control device outside the environmental chamber and ensuring its normal operation. The lines, cylinder, and hydraulic rod are detachable for easy movement and transportation. High and low temperature resistant hydraulic rod: It does not soften at high temperatures and does not freeze or crack at low temperatures, ensuring normal operation in the high and low temperature environmental chamber. Low temperature resistant hydraulic oil: Aviation-grade hydraulic oil that can flow at low temperatures, ensuring normal operation in the high and low temperature environmental chamber.

[0026] The working principle of this utility model is as follows: the first frame 1 and the second frame 2 are joined together and fixed with fixing bolts to prevent the frame from moving during the lifting process. The hydraulic pipeline is connected to the external hydraulic cylinder; only after the connection is made can the vehicle be moved to the platform.

[0027] The middle platform is placed between the two lifting platforms, and the ramp is placed at one end of the frame to facilitate the movement of vehicles onto the lifting platforms.

[0028] Move the vehicle onto the lifting platform. At this point, the platform and ramp can be removed, or the vehicle can be left in place and the stopper can be fixed to the fixed holes on the lifting platform with bolts to prevent the vehicle from sliding.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
