Description

Technical Field

[0001] This utility model relates to the technical field of four-wheel alignment devices, and more specifically, to a camera device and a four-wheel alignment device. Background Technology

[0002] With the rapid development of science and technology and the economy in my country, the number of cars owned by residents is growing rapidly. Vehicle inspection technology is also constantly evolving. As an important part of vehicle inspection, wheel alignment parameter testing has a significant impact on overall vehicle safety. Abnormal wheel alignment parameters can lead to a series of economic and safety issues, such as abnormal tire wear, vehicle drift, wheel shimmy, heavy steering, and increased fuel consumption, directly affecting driving safety and daily use.

[0003] Currently, non-contact four-wheel alignment machines on the market generally use image recognition to obtain tire image information, which is then used to detect the position of the four wheels of a car. However, in the pursuit of miniaturization, existing four-wheel alignment machines often result in the camera device being too close to the tire, causing the image of the tire to be too small, resulting in insufficient image recognition information and low recognition accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a camera device and a four-wheel alignment machine to solve the technical problem in the prior art where the camera device is too close to the tire, resulting in a small image of the tire, insufficient image recognition information, and low recognition accuracy.

[0015] In one embodiment, the end of the light guide post connected to the camera host is provided with a locking part, and the camera host is provided with a locking groove adapted to engage with the locking part, and the locking part engages with the locking groove.

[0016] By adopting the above technical solution, the connection between the light guide column and the camera host is made simple and reliable.

[0017] In one embodiment, the camera device further includes a retaining ring disposed on the camera opening and used to hold the lens between the retaining ring and the camera housing.

[0018] By adopting the above technical solution, the method of mounting the lens on the camera housing is easy to operate and helps to improve the efficiency of lens installation.

[0020] By adopting the above technical solution, the camera host is fixed inside the camera housing.

[0021] In one embodiment, the camera device further includes a communication component connected to the camera host, the communication component being used to enable the camera host to communicate with external devices.

[0022] By adopting the above technical solution, the tire images acquired by the camera host can be transmitted in a timely manner, thereby improving the intelligence level of the camera device.

[0023] In one embodiment, the camera housing is gradually widened along the direction close to the lens.

[0024] By adopting the above technical solution, the size of the camera device has been further reduced, making the camera device miniaturized.

[0025] Secondly, a four-wheel alignment device is provided, including a four-wheel alignment device body and the aforementioned camera device, wherein the camera device is connected to the four-wheel alignment device body and is used to acquire images of vehicle tires.

[0039] like Figures 1 to 3 As shown, this embodiment of the present invention provides a camera device for vehicle inspection operations, such as four-wheel alignment inspection. For example, the camera device is mounted near the vehicle tires to capture images of the tires. Here, the camera device acquires image information of the tires and analyzes the tire's positioning information accordingly. Specifically, in four-wheel alignment inspection, images can be projected onto the tire surface. The camera device acquires images of the tire surface and ultimately obtains the tire's positioning information based on these images. The camera device provided in this embodiment can acquire tire images while maintaining a close distance to the tires, thanks to its wide viewing angle. The following detailed description illustrates the specific implementation:

[0040] The camera device in this embodiment includes:

[0041] The camera housing 1, the camera host 2 disposed inside the camera housing 1, and the lens 3 connected to the camera of the camera host 2; wherein, the camera housing 1 is provided with a receiving cavity 11 for accommodating the camera host 2 and a camera opening 12 communicating with the receiving cavity 11, the lens 3 is disposed in the camera opening 12, the lens 3 is a convex lens 3, and a convex viewing surface 31 is provided on the side of the lens 3 away from the camera, the convex lens 3 is used to reduce the focal length of the camera host 2 to expand the viewing angle of the camera host 2.

[0042] Here, it can be understood that the camera housing 1 is used to protect and support the camera host 2 and the lens 3; the camera host 2 is used to acquire tire images, thereby analyzing the tire's positioning information; the lens 3 is used to adjust the focal length of the camera host 2, so that the viewing angle of the camera host 2 is expanded, ensuring that even when the camera host 2 is close to the tire, it can still obtain a complete image of the tire surface.

[0043] Specifically, the camera housing 1 serves as both a protective and support component. The camera housing 1 has a receiving cavity 11 and a camera opening 12. The receiving cavity 11 is located inside the camera housing 1, and the camera opening 12 extends through the camera housing 1 and communicates with the receiving cavity 11. The camera host 2 is located within the receiving cavity 11, with its camera facing the camera opening 12. A lens 3 is located within the camera opening 12 and covers the camera of the camera host 2. The lens 3 is a convex lens 3, wherein a convex viewing surface 31 is provided on the side of the lens 3 facing away from the camera host 2. The convex lens 3 is used to reduce the focal length of the camera host 2 to expand its viewing angle.

[0044] The working principle of the camera device provided in this embodiment is as follows:

[0045] The camera device is set up near the tire, and the camera is pointed at the tire surface to capture an image of the tire. Because the front of the camera is equipped with a convex lens 3, more reflected light from the tire surface can enter the convex lens 3 through the convex surface 31, and then enter the camera host 2 through the convex lens 3. That is, the focal length of the camera host 2 is adjusted, the viewing angle of the camera host 2 is increased, and thus the camera host 2 can obtain a wider field of view. In this way, the camera host 2 can obtain a more complete image of the tire at a closer distance.

[0046] By adopting the above technical solution, it is ensured that the camera device can still obtain a more complete tire image even when it is too close to the tire, thereby improving the amount of image recognition information and the accuracy of recognition.

[0047] In one embodiment, the lens 3 is provided with a light guide post 32. One end of the light guide post 32 is connected to the side of the lens 3 away from the convex surface 31, and the other end of the light guide post 32 away from the lens 3 is connected to the camera host 2. The light reflected from the tire surface enters the lens 3 through the convex surface 31 and then enters the camera host 2 through the light guide post 32.

[0048] Here, it can be understood that the light guide column 32 is used to guide the light entering the lens 3 into the camera host 2, and the light guide column 32 is also used to connect the lens 3 and the camera host 2.

[0049] Specifically, the light guide post 32 is made of a light guiding medium. After the light in the lens 3 enters the light guide post 32, it is guided by the light guide post 32 into the camera host 2.

[0050] By adopting the above technical solution, the distance between lens 3 and camera host 2 is increased, which is beneficial for the arrangement of internal components of the camera device.

[0051] In one embodiment, the light guide post 32 is coaxially arranged with the lens 3.

[0052] Here, it can be understood that when the camera device is used for four-wheel alignment detection, the camera device is roughly aligned with the center of the tire. That is, the light reflected from the tire surface shines from the periphery of the lens 3 towards the lens 3. Therefore, the direction of the light entering the lens 3 is roughly parallel to the radial direction of the lens 3, and at the same time, it converges at the center of the lens 3. At this time, the light guide column 32 is set coaxially with the lens 3, which is conducive to guiding the light in the lens 3 to the camera host 2.

[0053] By adopting the above technical solution, the light guide post 32 has improved its light conductivity.

[0054] In one embodiment, the diameter of the light guide post 32 is smaller than the diameter of the lens 3.

[0055] Here, it can be understood that the light guide post 32 is used to guide the light inside the lens 3. Since the light entering the lens 3 converges at the center of the lens 3, the diameter of the light guide post 32 can be set to be smaller than the diameter of the lens 3. In this way, the volume of the light guide post 32 is reduced while ensuring the light guiding function.

[0056] By adopting the above technical solution, the volume of the light guide column 32 is reduced, making the entire camera device miniaturized.

[0057] In one embodiment, the end of the light guide post 32 connected to the camera host 2 is provided with a locking part 321, and the camera host 2 is provided with a locking groove 21 that is adapted to and engages with the locking part 321, and the locking part 321 engages with the locking groove 21.

[0058] Here, it can be understood that the locking part 321 is used to connect the light guide column 32 and the camera host 2.

[0059] Specifically, the engaging part 321 is disposed on the light guide post 32. The engaging part 321 can be a frustum coaxial with the light guide post 32. The engaging groove 21 is disposed on the camera host 2. The engaging groove 21 can be a circular groove. The engaging part 321 is used to engage with the engaging groove 21, that is, the engaging part 321 is inserted into the engaging groove 21. The groove wall of the engaging groove 21 limits the radial movement of the engaging part 321, thus realizing the docking of the light guide post 32 and the camera host 2.

[0060] By adopting the above technical solution, the docking method between the light guide column 32 and the camera host 2 is simple and reliable.

[0061] In one embodiment, the camera device further includes a retaining ring 4, which is disposed on the camera opening 12 and is used to hold the lens 3 between the retaining ring 4 and the camera housing 1.

[0062] Here, it can be understood that the retaining ring 4 is used to hold the lens 3 between the retaining ring 4 and the camera housing 1, so that the retaining ring 4 is fixed on the camera housing 1.

[0063] Specifically, in this embodiment, the retaining ring 4 can be fixed to the camera housing 1 by means of a threaded connection, so that the installer can easily install the lens 3 onto the camera housing 1 without the aid of other tools.

[0064] By adopting the above technical solution, the operation of mounting the lens 3 on the camera housing 1 is simple and helps to improve the efficiency of lens 3 installation.

[0065] In one embodiment, the camera device further includes a camera host support 5, which is disposed inside the camera housing 1, and the camera host 2 is disposed on the camera host support 5.

[0066] Here, it can be understood that the camera host support 5 is used to support the camera host 2 and place the camera host 2 in a suitable position.

[0067] By adopting the above technical solution, the camera host 2 is fixed inside the camera housing 1.

[0068] In one embodiment, the camera device further includes a communication device 6, which is connected to the camera host 2 and is used to enable the camera host 2 to communicate with external devices.

[0069] Here, it can be understood that the communication device 6 is used to transmit the image information acquired by the camera host 2.

[0070] Specifically, the communication device 6 includes, but is not limited to, a communication connection cable, which can establish a communication connection between the camera host 2 and the outside world through wired or wireless means. For example, the communication device 6 is a Wi-Fi communication device 6, that is, the camera host 2 can connect to an external mobile terminal through a Wi-Fi wireless communication connection, so that the tire images acquired by the camera host 2 can be sent to the mobile terminal in a timely manner, making it convenient for operators to obtain tire information.

[0071] By adopting the above technical solution, the tire images acquired by the camera host 2 can be transmitted in a timely manner, thereby improving the intelligence level of the camera device.

[0072] In one embodiment, the camera housing 1 is gradually widened along the direction close to the lens 3.

[0073] Here, it can be understood that the shape of the camera housing 1 is adapted to the overall shape of the lens 3, the light guide column 32 and the camera host 2, so that the internal components of the camera housing 1 are arranged compactly, which can reduce the size of the camera device and make the camera device miniaturized.

[0074] By adopting the above technical solution, the size of the camera device has been further reduced, making the camera device miniaturized.

[0075] Secondly, a four-wheel alignment device is provided, including a four-wheel alignment device body and the aforementioned camera device, wherein the camera device is connected to the four-wheel alignment device body and is used to acquire images of vehicle tires.

[0076] It is understood that the four-wheel alignment device in this embodiment is used to detect the four-wheel alignment information of the vehicle. Of course, the four-wheel alignment device in this embodiment can also be used to detect other information of the vehicle, such as the calibration information of the vehicle radar components.

[0077] By adopting the above technical solution, in addition to the advantages of the camera device in the above embodiments, the four-wheel alignment instrument in this embodiment also has the advantages of being close to the tire to be tested during detection and occupying little space.

[0078] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
