Description

Technical Field

[0001] This utility model relates to the field of automotive repair and testing, and in particular to a rapid measurement and positioning device for the dimensions of an entire vehicle. Background Technology

[0002] In the fields of automotive repair and inspection, vehicle size measurement is a key step. To ensure accurate measurement data, the vehicle must be stably positioned before measurement to prevent the vehicle from shifting during the measurement process. Therefore, vehicle size measurement and positioning devices have become core auxiliary equipment in this field.

[0003] A search revealed Chinese Patent Publication No. CN221640687U, which discloses a positioning device for new energy vehicles. The device includes two sets of bosses, each with an inclined surface on both sides. A positioning component is located on the outer top of the boss, and this component includes a side plate. The side plate is positioned at the top of the planar end of the boss, and two clamping blocks are symmetrically arranged on its inner side. A second electric push rod moves the mounting bracket, clamping blocks, and limiting plate along the notch of the side plate and the slide groove towards the boss's delivery end, preventing the limiting plate from interfering with the vehicle's entry into the boss. The initial width of the boss is increased by the insertion plate and overlapping plate, facilitating vehicle entry. The positioning component then adjusts the clamping position according to the vehicle's width and length. The limiting plate then clamps and limits the two sides of the new energy vehicle's wheels, and a cylinder lifts the vehicle for bottom maintenance. The device is easy to store and its size can be changed, making it suitable for different models of new energy vehicles.

[0004] Although the device has some improvements and can achieve multi-faceted positioning of the tire, ensuring stability during vehicle size measurement, it requires multiple drive units to cooperate in clamping and positioning the tire. This leads to the following problems: First, the setting of multiple drive units increases the overall manufacturing cost and maintenance difficulty of the equipment. Failure of any drive unit will cause the positioning function to fail. Second, the linkage control of multiple drive units requires precise timing coordination. If the control program deviates, it will affect the positioning function. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rapid measurement and positioning device for the dimensions of an automobile, which aims to improve the problems of high manufacturing costs and difficult maintenance caused by multiple drive devices in the prior art, and the fact that the linkage control requires precise timing, which can easily lead to deviations that affect positioning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid measurement and positioning device for the dimensions of an automobile, comprising a support platform, a lifting platform provided on the upper surface of the support platform, and a positioning component provided on the upper surface of the lifting platform;

A guide plate is threadedly connected to the outer wall of the bidirectional threaded rod. A clamping plate is elastically connected to the left surface of the guide plate through a compression spring. A reinforcement component is provided on the side of the guide plate near the center of the lifting platform.

One end of a connecting plate is fixedly connected to the outer wall of the round rod. A second round rod is slidably connected to the inner surface of the other end of the connecting plate.

[0010] As a further description of the above technical solution:

[0011] The front end of the support platform is designed to be inclined, with the front lower than the back.

[0012] As a further description of the above technical solution:

[0013] The bidirectional threaded rod passes through and is rotatably connected to the inner surfaces of the two sets of support plates.

[0028] 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 protection scope of the present utility model.

[0029] Reference Figures 1-2This utility model provides an embodiment of a vehicle size rapid measurement and positioning device, including a support platform 1, which serves as the base of the device and supports the entire device. A lifting platform 2 is provided on the upper surface of the support platform 1. The lifting platform 2 is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The lifting platform 2 is used to lift the car to facilitate the measurement of the car's size. The lifting platform 2 is driven by a built-in hydraulic device. A positioning component 3 is provided on the upper surface of the lifting platform 2. The positioning component 3 can position the car to avoid deviation during measurement and ensure measurement accuracy.

[0030] Reference Figures 1-3 The positioning component 3 includes a support plate 31, which is provided in two sets. The two sets of support plates 31 are symmetrically fixedly connected to the left and right ends of the upper surface of the lifting platform 2. A motor 32 is provided at the right end of the support plate 31 on the right side. The motor 32 is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The motor 32 is located at the rear of the right end of the support plate 31 on the right side. The output shaft of the motor 32 is fixedly connected to a bidirectional threaded rod 33. The outer surface of the bidirectional threaded rod 33 has two sets of threaded grooves designed symmetrically on the left and right sides, and the rotation directions of the two sets of threaded grooves are opposite. A guide plate 34 is threadedly connected to the outer wall of the bidirectional threaded rod 33. When the bidirectional threaded rod 33 rotates, it will drive the guide plate 34 to move towards the center or edge of the lifting platform 2. A clamping plate 36 is elastically connected to the left surface of the guide plate 34 through a compression spring 35. The clamping plate 36 is used to clamp and position the left and right sides of the car tire. A reinforcing component 4 is provided on the side of the guide plate 34 near the center of the lifting platform 2.

[0031] Reference Figures 1-3 The front end of the support platform 1 is set to be inclined with the front lower and the rear higher, which makes it convenient for the car to drive onto the lifting platform 2. After the measurement is completed, the car can leave the support platform 1 by reversing. The bidirectional threaded rod 33 passes through and is rotatably connected to the inner surface of the two sets of support plates 31. The guide plate 34 and the clamping plate 36 are slidably connected to the upper surface of the lifting platform 2. The lower surface of the guide plate 34 and the clamping plate 36 is provided with protrusions. The lifting platform 2 is provided with guide grooves, which fit with the protrusions. There are multiple sets of guide plates 34, compression springs 35 and clamping plates 36. The multiple sets of guide plates 34, compression springs 35 and clamping plates 36 are symmetrically distributed on the left and right with the center line of the lifting platform 2 as the axis. The compression spring 35 is used to control the distance between the clamping plate 36 and the guide plate 34 when there is no external force.

[0032] Reference Figures 1-3The reinforcement component 4 includes a hinge seat 42, which is slidably connected to the inner surface of the clamping plate 36. The hinge seat 42 slides in the front-rear direction. A side plate 41 is fixedly connected to the left surface of the hinge seat 42. The side plate 41 is used to clamp and fix the front and rear sides of the tire, which can further ensure the stability of the vehicle. A round rod 43 is rotatably connected to the inner surface of the hinge seat 42. One end of a connecting plate 44 is fixedly connected to the outer wall of the round rod 43. A round rod 45 is slidably connected to the inner surface of the other end of the connecting plate 44. Both the round rod 43 and the round rod 45 are rotation axes. The hinge seat 42 is provided with sliding keys on both the upper and lower surfaces. The inner surface of the clamping plate 36 is provided with a sliding groove. The sliding key is slidably connected to the inner wall of the sliding groove. The round rod 45 is rotatably connected to the inner surface of the guide plate 34. The connecting plate 44 penetrates the left surface of the guide plate 34 and the right surface of the hinge seat 42. The connecting plate 44 is inclined as a whole. Multiple sets of reinforcing components 4 are provided. The multiple sets of reinforcing components 4 are symmetrically distributed front and back with the center line of the clamping plate 36 as the axis. When the clamping plate 36 and the guide plate 34 are close, the connecting plate 44 will drive the side plate 41 to move towards the middle of the clamping plate 36.

[0033] Working principle: First, the car can drive along the inclined structure of the front end of the support platform 1 (lower at the front and higher at the rear) to the middle position on the lifting platform 2. Then, the motor 32 is started, which drives the bidirectional threaded rod 33 to rotate, thereby driving the guide plate 34 to move towards the center of the lifting platform 2. During the movement of the guide plate 34, the clamping plate 36 connected by the compression spring 35 gradually approaches the car tire until the clamping plate 36 contacts the left and right sides of the tire, thereby achieving left and right positioning of the car.

[0034] After the clamping plate 36 moves with the guide plate 34 and comes into contact with the tire, as the guide plate 34 continues to move closer to the center, the distance between the guide plate 34 and the clamping plate 36 gradually decreases. The second round rod 45 on the inner side of the guide plate 34 drives the connecting plate 44 to rotate. The connecting plate 44 pulls the hinge seat 42 through the first round rod 43 at the other end, causing the hinge seat 42 to move towards the center of the lifting platform 2, thereby driving the side plate 41 on the left end of the hinge seat 42 to move closer to the front and rear sides of the tire until the side plate 41 is in contact with the front and rear surfaces of the tire, thus completing the positioning of the car in the front and rear direction. Then the motor 32 is turned off to maintain the stability of the car.

[0035] Then start the lifting platform 2 to raise the car to the appropriate measurement height. After the measurement is completed, lower the lifting platform 2, then start the motor 32 to drive the bidirectional threaded rod 33 to reverse and release the positioning of the car. Then reverse the car away from the support platform 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
