Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, and in particular to a four-wheel alignment laser signal receiving module with multi-channel parallel data processing. Background Technology

[0002] Multichannel data refers to data that is simultaneously acquired, transmitted, and processed through multiple independent transmission paths or processing units. It can achieve synchronous interaction of multi-source information with the help of parallel architecture. For example, in sensor networks, multiple channels are used to collect physical signals from different locations in parallel, or in communication systems, multiple channels are used to increase data transmission bandwidth. Its core advantage lies in breaking through the processing bottleneck of a single channel and improving data processing efficiency, enhancing system real-time performance and reliability in an efficient and collaborative manner. It is widely used in fields with high requirements for data processing speed and capacity, such as industrial monitoring, medical imaging, and intelligent transportation.

[0003] The multi-channel parallel data processing four-wheel alignment laser signal receiving module is a core component of automotive testing that uses a multi-channel parallel architecture to synchronously process laser reflection signals to quickly and accurately obtain wheel alignment parameters. The existing fixing method uses a level and welding technology to weld the signal receiving module to the surface of the equipment. However, replacing the module when it fails is very complicated, requiring cutting and grinding to damage the weld points. This process can damage the surface of the equipment (such as leaving scratches and dents) and even reduce the structural strength of the equipment (such as stress concentration after cutting the weld, shortening the fatigue life). Existing technology uses guide rail interfaces on the bottom or side of the signal receiving module's housing to install the signal receiving module horizontally or vertically. However, the guide rail installation relies on the friction between the clamps and the rail and lacks a rigid locking design. In vibration scenarios, the module may slide laterally or bounce up and down along the rail, causing the internal cable interface to loosen, which in turn affects the positional accuracy of the laser signal reception. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a four-wheel positioning laser signal receiving module with multi-channel data parallel processing. It aims to improve the existing technology of horizontal or vertical installation of the signal receiving module by means of a track. However, the track installation relies on the friction between the clamp and the track and the buckle structure, without a rigid locking design. In vibration scenarios, the module will slide laterally or jump up and down along the track, causing the internal cable interface to loosen, which in turn affects the positional accuracy of the laser signal reception.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a four-wheel positioning laser signal receiving module for multi-channel data parallel processing, including a housing, a fixing mechanism installed on the top of the outer wall of the housing for fixing the housing, a protective mechanism installed on the front side of the outer wall of the housing for shielding dust; the fixing mechanism includes a top plate installed on the top of the outer wall of the housing, multiple limiting posts are fixedly connected at equal intervals on the bottom of the outer wall of the top plate, multiple buckles are slidably connected on the bottom of the outer wall of the top plate, a threaded rod is threadedly connected to the middle of the buckle, a limiting plate is installed on the left and right ends of the outer wall of the threaded rod, the top of the outer wall of the multiple limiting plates is fixedly connected to the bottom of the outer wall of the top plate, the lower inner wall of the limiting plate is rotatably connected to the outer wall of the threaded rod, and a fixing plate is installed on the bottom of the outer wall of the top plate.

[0006] As a further description of the above technical solution:

[0007] The protective mechanism includes a fixing frame, which is installed on the front side of the outer wall of the housing. A rotating shaft is installed on the outer front end of the fixing frame. A baffle is fixedly connected to the outer wall of the rotating shaft. Fixing shafts are fixedly connected to the bottom left and right sides of the outer wall of the baffle. Limiting frames are fixedly connected to the bottom left and right sides of the outer wall of the fixing frame. The outer wall of the fixing shaft is slidably connected to the inner wall of the middle part of the limiting frame. A pressing frame is slidably connected to the other end of each of the multiple limiting frames. Limiting buckles are fixedly connected to adjacent sides of the outer walls of the multiple pressing frames. The outer walls of the limiting buckles are slidably connected to the inner walls of the limiting frames. Springs are fixedly connected to adjacent sides of the outer walls of the multiple limiting buckles.

[0008] As a further description of the above technical solution:

[0009] Limiting grooves are provided at the four corners of the top plate, and the interior of each of the limiting grooves is slidably connected to the outer wall of the limiting column.

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

[0011] The bottom of the outer wall of the fixing plate is provided with fixing grooves on both the left and right sides, and the interior of each fixing groove is slidably connected to the bottom of the outer wall of the buckle.

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

[0013] Limiting plates are installed on both the left and right ends of the outer wall of the rotating shaft. The rear side of the outer wall of the multiple limiting plates is fixedly connected to the front side of the outer wall of the fixed frame. The front end of the rotating shaft is rotatably connected to the outer wall of the limiting plates.

[0014] As a further description of the above technical solution:

[0015] Each of the outer walls of the multiple limiting frames is fixedly connected to a support frame on the side away from each other, and the inner wall of the support frame is fixedly connected to the other end of the outer wall of the spring.

[0016] As a further description of the above technical solution:

[0017] Multiple slots are fixedly provided at equal intervals around the perimeter of the outer shell, and the interior of each slot is slidably connected to the bottom of the outer wall of the fixing plate.

[0018] As a further description of the above technical solution:

[0019] An interface is installed at the center of the front end of the housing, and the interface is installed at the rear end of the outer side of the protective mechanism.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a tool is used to rotate the threaded rod. The inner wall of the lower part of the limiting plate supports the rotation of the threaded rod and is fixed to the bottom of the top plate. Under the action of the top plate restricting the rotation of the buckles, multiple buckles move towards each other and move the bottom end into the fixing groove of the fixing plate. Because the bottom of the fixing plate matches the outer groove of the outer shell, the outer shell is fixed. This solves the problem that when the signal receiving module is installed on the guide rail, the lack of rigid locking causes the module to slide and jump during vibration, resulting in loose cable interfaces and affecting the position accuracy of laser signal reception.

[0022] 2. In this utility model, the fixed shaft has a space inside for the sliding of the limit buckle. When the limit buckle is engaged with the fixed shaft, it locks the fixed shaft and thus locks the baffle, blocking the fixed interface. When the baffle needs to be opened, the press frame is pressed, the limit buckle squeezes the spring and moves out of the fixed shaft, and the baffle can rotate around the rotating shaft to complete the unlocking, realizing the cycle operation of "press to unlock, rotate the baffle, release and lock", which prevents dust from entering the equipment from the interface and damaging the life of the components.

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a four-wheel positioning laser signal receiving module with multi-channel parallel data processing, comprising a housing 1, a fixing mechanism 2 installed on the top of the outer wall of the housing 1 for fixing the housing 1, and a protective mechanism 3 installed on the front side of the outer wall of the housing 1 for shielding against dust; the fixing mechanism 2 includes a top plate 201 installed on the top of the outer wall of the housing 1, a plurality of limiting posts 202 are fixedly connected at equal intervals on the bottom of the outer wall of the top plate 201, and a plurality of buckles 207 are slidably connected on the bottom of the outer wall of the top plate 201, with a threaded rod 205 threadedly connected to the center of the buckle 207. Limiting plates 206 are installed on both the left and right ends of the outer wall of the threaded rod 205. The top of the outer wall of the multiple limiting plates 206 is fixedly connected to the bottom of the outer wall of the top plate 201. The inner wall of the middle and lower part of the limiting plate 206 is rotatably connected to the outer wall of the threaded rod 205. A fixing plate 204 is installed on the bottom of the outer wall of the top plate 201. Limiting grooves 203 are opened at the four corners of the top plate 201. The interior of the multiple limiting grooves 203 is slidably connected to the outer wall of the limiting post 202. Fixing grooves 208 are opened on both the left and right sides of the bottom of the outer wall of the fixing plate 204. The interior of the multiple fixing grooves 208 is slidably connected to the bottom of the outer wall of the buckle 207.

[0033] Specifically, when the threaded rod 205 is rotated using a tool, the lower inner wall of the limiting plate 206 provides support for the threaded rod 205 to rotate in place. The limiting plate 206 is fixed to the bottom of the top plate 201, forming a stable rotation fulcrum. Under the rotational restriction effect of the top plate 201 on the latches 207, multiple latches 207 will move towards or away from each other along the axial direction of the threaded rod 205. When the latches 207 move, their bottom ends precisely move into the fixing groove 208 on the fixing plate 204, achieving a firm fixation of the fixing plate 204. This is because the bottom structure of the fixing plate 204 and the groove opened on the outer side of the outer shell 1... 4. Precise fit ensures stable fixation of the outer shell 1. Simultaneously, the limiting grooves 203 at the four corners of the top plate 201 allow the limiting posts 202 to slide smoothly within them, further enhancing the stability of the fixing mechanism 2 during the fixing process. This solves the problem that when the signal receiving module is installed horizontally or vertically on the bottom or side of the outer shell 1 of the signal receiving module, the guide rail installation relies solely on the friction between the clamping feet and the rail, lacking a rigid locking design. In vibration scenarios, the module is prone to sliding laterally along the rail or jumping up and down, causing the internal cables to loosen, which in turn affects the positional accuracy of the laser signal reception.

[0034] Reference Figure 3 , Figure 5 and Figure 6The protective mechanism 3 includes a fixing frame 301, which is installed on the front side of the outer wall of the outer shell 1. A rotating shaft 303 is installed on the outer front end of the fixing frame 301. A baffle 304 is fixedly connected to the outer wall of the rotating shaft 303. Fixing shafts 305 are fixedly connected to the left and right sides of the bottom of the outer wall of the baffle 304. Limiting frames 306 are fixedly connected to the left and right sides of the bottom of the outer wall of the fixing frame 301. The outer wall of the fixing shaft 305 is slidably connected to the inner wall of the middle part of the limiting frame 306. Pressing frames 307 are slidably connected to the other end of the multiple limiting frames 306. The outer walls of the multiple pressing frames 307 are fixed on adjacent sides. A limit buckle 308 is connected, and the outer wall of the limit buckle 308 is slidably connected to the inner wall of the limit frame 306. A spring 309 is fixedly connected to the adjacent side of the outer wall of multiple limit buckles 308. Limit plates 302 are installed on the left and right ends of the outer wall of the rotating shaft 303. The rear side of the outer wall of multiple limit plates 302 is fixedly connected to the front side of the outer wall of the fixed frame 301. The front end of the rotating shaft 303 is rotatably connected to the outer wall of the limit plate 302. A support frame 310 is fixedly connected to the side of the outer wall of multiple limit frames 306 that is far apart. The inner wall of the support frame 310 is fixedly connected to the other end of the outer wall of the spring 309.

[0035] Specifically, manually pressing the left and right pressing brackets 307 will cause the limiting buckle 308 to move synchronously outward from the limiting frame 306. During this process, the limiting buckle 308 compresses the spring 309, putting the spring 309 into a compressed and stored state. Subsequently, the baffle 304 is rotated around the rotating shaft 303. The fixed shaft 305 at the bottom of the baffle 304 slides smoothly into the limiting frame 306 along the inner wall of the middle part of the limiting frame 306. When the fixed shaft 305 is fully inside the limiting frame 306, the pressing bracket 307 is released. The compressed spring 309, due to its elastic restoring characteristic, pushes the limiting buckle 308 to move inward from the limiting frame 306. The internal space of the 05 is pre-designed to allow the limit buckle 308 to slide. When the limit buckle 308 is precisely engaged inside the fixed shaft 305, it will form a mechanical lock, locking the fixed shaft 305 and thus locking the position of the baffle 304, achieving a stable cover and fixation of the interface 5. If it is necessary to open the baffle 304, press the press bracket 307 again, and the limit buckle 308 will re-compress the spring 309 and move out of the fixed shaft 305, releasing the locking restriction on the baffle 304. At this time, the baffle 304 can rotate freely around the rotating shaft 303, exposing the interface 5 and completing the unlocking operation. This effectively prevents dust from entering the equipment from the interface 5 and prevents the components from having a shortened service life due to dust intrusion.

[0036] Reference Figure 1 , Figure 2 and Figure 3Multiple slots 4 are fixedly provided at equal intervals around the outer shell 1. The interior of each slot 4 is slidably connected to the bottom of the outer wall of the fixing plate 204, which can be used to fix the outer shell 1 in conjunction with the fixing plate 204. An interface 5 is installed in the middle of the front end of the outer shell 1. The interface 5 is installed on the outer rear end of the protective mechanism 3.

[0037] Specifically, multiple slots 4 are evenly spaced and fixedly opened around the perimeter of the outer casing 1. These slots 4 form a sliding fit structure with the bottom of the outer wall of the fixing plate 204. Through the cooperation of the slots 4 and the fixing plate 204, the outer casing 1 can be firmly fixed, ensuring that it remains stable during equipment operation. An interface 5 is installed at the center of the front end of the outer casing 1. The protective mechanism 3 is arranged around the interface 5, which can effectively resist the interference and damage of external factors to the interface 5, and provide reliable protection for the normal use of the interface 5.

[0038] Working principle: When the threaded rod 205 is rotated using a tool, the lower inner wall of the limiting plate 206 allows the threaded rod 205 to rotate in place. Since the limiting plate 206 is fixed to the bottom of the top plate 201, the top plate 201 restricts the rotation of the latches 207, causing multiple latches 207 to move towards or away from each other. When the latches 207 move, their bottom ends move into the fixing grooves 208 on the fixing plate 204, thus fixing the fixing plate 204. Because the bottom structure of the fixing plate 204 matches the grooves 4 on the outer side of the outer shell 1, it can... It can fix the outer shell 1, and the limiting grooves 203 opened at the four corners of the top plate 201 allow the limiting post 202 to slide in them, which further enhances the stability of the fixing mechanism 2 during the fixing process. It solves the problem that when the signal receiving module is installed on the bottom or side of the outer shell 1, the signal receiving module is installed horizontally or vertically through the track. However, the installation of the track relies on the friction between the clamp and the track. Without a rigid locking design, the module will slide horizontally or jump up and down along the track in the vibration scenario, which will cause the internal cable to loosen and thus affect the positional accuracy of the laser signal reception.

[0039] Manually pressing the left and right pressing brackets 307 will cause the pressing brackets 307 to move the limit buckles 308 synchronously to the outside of the limit frame 306. At this time, the limit buckles 308 will compress the spring 309 to store energy. Then, the baffle 304 will rotate around the pivot 303. The fixed shaft 305 at the bottom of the baffle 304 will slide into the interior of the limit frame 306 along the middle inner wall. After the fixed shaft 305 is fully inside the limit frame 306, the pressing brackets 307 will be released. At this time, the compressed spring 309 will return to its elastic state and push the limit buckles 308 to move into the interior of the limit frame 306. Space is reserved inside the fixed shaft 305 for the sliding of the limit buckle 308. When the limit buckle 308 is precisely engaged inside the fixed shaft 305, it will lock the fixed shaft 305, thereby locking the position of the baffle 304 and achieving the blocking and fixing of the interface 5. When it is necessary to open the baffle 304, the action of pressing the press bracket 307 is repeated. The limit buckle 308 will squeeze the spring 309 again and move out of the fixed shaft 305. At this time, the baffle 304 can rotate freely around the rotating shaft 303, thereby exposing the interface 5 and completing the unlocking operation. This prevents dust from entering the device from the interface 5 and damaging the life of the components.

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.
