Description

Technical Field

[0001] This utility model belongs to the technical field of signal receiver module components, specifically relating to an automotive lidar signal receiver module component. Background Technology

[0002] A vehicle-mounted lidar (LiDAR) is a radar system that detects the distance, orientation, speed, and surface characteristics of a target object by emitting a laser beam and receiving the reflected signal. Its core components include a laser emitter, a scanning system, an optical receiver, and a signal processing system. The receiver module is a modular type and does not contain a built-in decoding integrated circuit. Therefore, the receiver circuit is only a component and can only function properly through secondary development within a specific circuit. This design has many advantages; it can be used with various decoding circuits or microcontrollers, and the circuit design is flexible and convenient.

[0003] During normal storage, the surface of the existing receiver module will be covered with a layer of dust. Since the integrated circuits on the receiver module are relatively fragile, they cannot be cleaned vigorously. As a result, a lot of dust will get stuck in the receiver module, affecting its normal use in the future. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive lidar signal receiver module assembly to solve the problem mentioned in the background art that, during daily storage, the surface of the existing receiver module assembly will be covered with a layer of dust. Since the integrated circuits on the receiver module assembly are relatively fragile, the receiver module assembly cannot be cleaned vigorously, resulting in a lot of dust being trapped in the receiver module assembly, which affects the normal use of the receiver module assembly in the later stage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a modular component body and a U-shaped support. The modular component body is located within the support. Channels are provided on both the front and rear sides of the support. Slide plates are slidably installed within the channels. Limiting components are provided on the slide plates. A rotating shaft is rotatably installed between the two slide plates. Two slide plates extend through both ends of the rotating shaft. Gears are installed at both ends of the rotating shaft. L-shaped fixing plates are installed on both the front and rear sides of the support. A toothed plate meshing with the gears is installed on the upper surface of the vertical portion of the fixing plate. The same U-shaped operating plate is installed at both ends of the rotating shaft. A cleaning brush is installed on the rotating shaft, and the bristles of the cleaning brush are in contact with the modular component body.

[0006] By adopting the above solution, a rotating shaft, gears, toothed plates, and cleaning brush cylinder are set up. The rotating shaft is slidably supported on the bracket by the channel and the sliding plate. Combined with the meshing of the toothed plates and gears, the cleaning brush cylinder rotates to clean the dust on the main body of the module component by moving the operating plate and cooperating with the meshing of the gears and toothed plates. This ensures that no dust is trapped on the main body of the module component and that the main body of the module component can be used normally.

[0007] In a preferred embodiment, a base plate is installed on the lower surface of both the front and rear ends of the bracket, a silicone pad is installed on the lower surface of the base plate, and a sponge sleeve is installed on the horizontal portion of the operating panel.

[0008] By adopting the above solution, a base plate, silicone pad, and sponge sleeve are used. The base plate fixes the silicone pad to the bottom of the bracket, and the silicone pad increases the friction between the bracket and the table, improving the stability and sturdiness of the bracket. The sponge sleeve wraps the horizontal part of the control panel, thereby improving the comfort of the operator's hands.

[0009] In a preferred embodiment, the limiting component includes four sets of L-shaped limiting plates, with two limiting plates in each set, and the limiting plates in the same two sets are respectively installed on the front and rear sides of the same sliding plate.

[0010] By adopting the above solution, a limiting plate is set up. The limiting plate is L-shaped and limits the front and rear sides of the skateboard, thereby locking the skateboard in the channel. This allows the skateboard to move stably in the channel, preventing the skateboard from falling out of the channel and improving the stability of the skateboard.

[0011] In a preferred embodiment, a sliding rod is slidably installed on both the front and rear sides of the bracket. A clamping plate is installed at one end of the sliding rod, and the main body of the module assembly is located between the two clamping plates. A pull plate is installed at the other end of the sliding rod, and a spring is sleeved on the sliding rod, with its two ends respectively fixedly connected to the pull plate and the bracket.

[0012] By adopting the above solution, a sliding rod, a spring, and a clamping plate are set up. The sliding plate is mounted on the bracket to provide sliding support for the clamping plate. The pull plate allows the operator to move the sliding rod. The spring provides elastic support for the clamping plate. This allows the two clamping plates to clamp and fix the main body of the module component, preventing the main body of the module component from moving during the dust cleaning process.

[0013] In a preferred embodiment, two telescopic rods are installed on both the front and rear sides of the inner wall of the bracket. The two telescopic rods on the same side are located on the left and right sides of the slide rod, respectively, and the telescopic shaft of the telescopic rod is fixedly connected to the clamping plate on the same side.

[0014] By adopting the above scheme, by setting up a telescopic rod, the clamping plate is reinforced and supported by the telescopic rod located on the left and right sides of the slide rod, thereby improving the balance and stability of the clamping plate, so that the clamping plate moves stably with the movement of the slide rod, and the structure is simple.

[0015] In a preferred embodiment, support plates are provided on both the left and right sides of the upper surface of the bracket. A threaded rod is rotatably mounted on the upper surface of the support plate, and a movable plate is threaded onto the threaded rod. An L-shaped support plate is mounted on one end of the movable plate, and the lateral portion of the support plate is located on the lower surface of the main body of the module component.

[0016] By adopting the above solution, a support plate, a threaded rod, and a support plate are set up. The support plate provides rotational support for the threaded rod. Combined with the threaded installation of the movable plate, and the fixed connection between the support plate and the movable plate, the movable plate moves the support plate when the threaded rod is rotated. This allows for adjustment of the distance between the main body of the module component and the cleaning brush cylinder, thus expanding the applicability of the bracket.

[0017] In a preferred embodiment, mounting plates are installed on both the front and rear sides of the support plate, and fastening bolts are threaded onto the mounting plates, with the tail ends of the fastening bolts threadedly connected to the bracket.

[0018] By adopting the above scheme, by setting up an installation plate and fastening bolts, the installation plate provides threaded support for the fastening bolts, and the fastening bolts provide threaded fixation for the support plate. This allows for easy disassembly of the support plate by loosening the fastening bolts at any time, and thus disassembly of the tray, making the operation convenient.

[0019] In a preferred embodiment, a second telescopic rod is installed on the upper surface of the support plate, and the telescopic shaft of the second telescopic rod is fixedly connected to the movable plate.

[0020] By adopting the above scheme, by setting up a second telescopic rod, the extension of the second telescopic rod is used to limit and support the moving plate, so that the moving plate can only move up and down under the drive of the threaded rod, avoiding the moving plate from rotating with the rotation of the threaded rod, thereby improving the stability of the moving plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This automotive lidar signal receiver module assembly uses a rotating shaft, gears, toothed plates, and a cleaning brush to slide and support the rotating shaft on a bracket. Combined with the meshing of the toothed plates and gears, the cleaning brush rotates by moving the control panel, which in turn cleans the dust off the module assembly body. This prevents dust from getting stuck on the module assembly body and ensures that the module assembly body can be used normally.

[0023] This automotive lidar signal receiver module uses a sliding rod, spring, and clamping plate. The sliding plate is mounted on the bracket, providing sliding support for the clamping plate. The pull plate allows the operator to easily move the sliding rod, and the spring provides elastic support for the clamping plate. This allows the two clamping plates to clamp and fix the main body of the module, preventing the main body of the module from moving during dust cleaning. Attached Figure Description

[0028] Please see Figure 1-3This utility model provides an automotive lidar signal receiver module assembly, including a module assembly body 1 and a U-shaped bracket 2. The module assembly body 1 is located inside the bracket 2. Channels are provided on both the front and rear sides of the bracket 2 to accommodate sliding plates 3. The sliding plates 3 are slidably installed in the channels and support the rotation of a rotating shaft 4. Limiting components are provided on the sliding plates 3. A rotating shaft 4 is rotatably installed between the two sliding plates 3 and supports the rotation of a cleaning brush cylinder 8. Two sliding plates 3 extend through both ends of the rotating shaft 4. Gears 5 are installed at both ends of the rotating shaft 4 and mesh with toothed plates 6. L-shaped fixing plates 7 are installed on both the front and rear sides of the bracket 2 to support the toothed plates 6. The upper surface of the vertical part of the fixing plate 7... A gear plate 6 is installed that meshes with gear 5. Both ends of the rotating shaft 4 are equipped with the same U-shaped operating plate 9. The operating plate 9 drives the rotating shaft 4 to move. A cleaning brush 8 is installed on the rotating shaft 4. The cleaning brush 8 cleans the dust on the main body 1 of the module component. The bristles of the cleaning brush 8 contact the main body 1 of the module component. By setting up the rotating shaft 4, gear 5, gear plate 6, and cleaning brush 8, and utilizing the channel and slide plate 3, the rotating shaft 4 is slidably supported on the bracket 2. Combined with the meshing action of gear plate 6 and gear 5, by moving the operating plate 9, and in conjunction with the meshing action of gear 5 and gear plate 6, the cleaning brush 8 rotates to clean the dust on the main body 1 of the module component, ensuring that no dust remains on the main body 1 and that the main body 1 can be used normally.

[0029] Base plates 16 are installed on the lower surfaces of both the front and rear ends of the bracket 2. The base plates 16 are used to fix and support the silicone pads 17. The silicone pads 17 are installed on the lower surface of the base plates 16 to increase the friction between the bottom of the bracket 2 and the table. A sponge sleeve is installed on the horizontal part of the operating panel 9 to wrap the horizontal part of the operating panel 9, thereby improving the comfort of the operating panel 9. By setting up the base plates 16, silicone pads 17, and sponge sleeves, the base plates 16 fix the silicone pads 17 to the bottom of the bracket 2. Combined with the function of the silicone pads 17, the friction between the bracket 2 and the table is increased, which improves the stability and firmness of the bracket 2. Combined with the function of the sponge sleeve, the horizontal part of the operating panel 9 is wrapped, thereby improving the comfort of the operator's hands.

[0030] The limiting component includes four sets of L-shaped limiting plates 15. The limiting plates 15 limit the slide plate 3, ensuring that the slide plate 3 can move stably within the channel and preventing the slide plate 3 from sliding out of the channel. Each set of limiting plates 15 consists of two plates, and the two sets of limiting plates 15 are installed on the front and rear sides of the same slide plate 3 respectively. By setting the limiting plates 15, the front and rear sides of the slide plate 3 are limited by the L-shape of the limiting plates 15, thereby locking the slide plate 3 in the channel, allowing the slide plate 3 to move stably within the channel, preventing the slide plate 3 from falling out of the channel, and improving the stability of the slide plate 3.

[0031] Slide rods 11 are slidably installed on both the front and rear sides of the bracket 2. These slide rods 11 support the clamping plate 10 and the pull plate 13. A clamping plate 10 is installed at one end of the slide rod 11, clamping and fixing the main body 1 of the module assembly. The main body 1 of the module assembly is located between the two clamping plates 10. A pull plate 13 is installed at the other end of the slide rod 11, facilitating the movement of the slide rod 11. Springs 12 are sleeved on the slide rod 11, with both ends fixedly connected to the pull plate 13 and the bracket 2 respectively. The springs 12 support the clamping plate 10. Elastic support is provided so that the clamping plate 10 can clamp the main body 1 of the module component. By setting up the sliding rod 11, spring 12 and clamping plate 10, the sliding plate 3 is slidably mounted on the bracket 2 to provide sliding support for the clamping plate 10. The pull plate 13 is used to facilitate the operator to move the sliding rod 11. With the elastic action of the spring 12, the clamping plate 10 is elastically supported, so that the two clamping plates 10 can clamp and fix the main body 1 of the module component, and prevent the main body 1 of the module component from moving during the dust cleaning process.

[0032] Two telescopic rods 14 are installed on both the front and rear sides of the inner wall of the bracket 2. The telescopic rods 14 are used to strengthen the support of the clamping plate 10 and improve its balance. The two telescopic rods 14 on the same side are located on the left and right sides of the slide rod 11, respectively. The telescopic shaft of the telescopic rod 14 is fixedly connected to the clamping plate 10 on the same side. By setting the telescopic rods 14, the clamping plate 10 is strengthened by the telescopic rods 14 located on the left and right sides of the slide rod 11, thereby improving the balance and stability of the clamping plate 10. This allows the clamping plate 10 to move stably as the slide rod 11 moves. The structure is simple.

[0033] Support plates 18 are provided on both the left and right sides of the upper surface of the bracket 2. The support plates 18 are used to rotate and support the threaded rod 19. The threaded rod 19 is rotatably installed on the upper surface of the support plate 18 and supports the movable plate 20. The movable plate 20 is threaded on the threaded rod 19 and supports the support plate 21. An L-shaped support plate 21 is installed at one end of the movable plate 20 and supports the main body 1 of the module assembly. The horizontal part of the support plate 21 is located on the lower surface of the main body 1 of the module assembly. By setting up the support plate 18, the threaded rod 19, and the support plate 21, the support plate 18 rotates and supports the threaded rod 19. Combined with the threaded installation of the movable plate 20 and the fixed connection between the support plate 21 and the movable plate 20, when the threaded rod 19 is rotated, the movable plate 20 drives the support plate 21 to move, thereby adjusting the distance between the main body 1 of the module assembly and the cleaning brush cylinder 8, thus expanding the applicability of the bracket 2.

[0034] Mounting plates 23 are installed on both the front and rear sides of the support plate 18. The mounting plates 23 are used to thread the fastening bolts 24. The fastening bolts 24 are threaded on the mounting plates 23 and used to thread the support plate 18. The tail end of the fastening bolts 24 is threaded to the bracket 2. By setting up the mounting plates 23 and the fastening bolts 24, the mounting plates 23 provide threaded support for the fastening bolts 24. Combined with the threaded fixing function of the fastening bolts 24 to the support plate 18, it is convenient to loosen the fastening bolts 24 at any time to disassemble the support plate 18 and then disassemble the support plate 21. The operation is convenient.

[0035] A telescopic rod 22 is installed on the upper surface of the support plate 18. The telescopic rod 22 is used to limit and support the moving plate 20. The telescopic shaft of the telescopic rod 22 is fixedly connected to the moving plate 20. By setting the telescopic rod 22, the extension of the telescopic rod 22 is used to limit and support the moving plate 20, so that the moving plate 20 can only move up and down under the drive of the threaded rod 19, avoiding the moving plate 20 from rotating with the rotation of the threaded rod 19, thereby improving the stability of the moving plate 20.

[0036] In use, when it is necessary to adjust the distance between the main body 1 of the module component and the cleaning brush cylinder 8, the pull plate 13 is moved. The pull plate 13 drives the slide rod 11 to move, and the slide rod 11 drives the clamping plate 10 to move. When the pull plate 13 moves, it stretches the spring 12, placing the main body 1 of the module component on the transverse part of the two support plates 21. When the pull plate 13 is released, the clamping plate 10 is driven by the reaction force of the spring 12 to clamp the main body 1 of the module component. When the clamping plate 10 moves, it stretches the telescopic rod 14. Alternatively, by compression, the telescopic rods 14, located on the left and right sides of the slide rod 11, reinforce the clamping plate 10, thereby improving its balance and stability. This allows the clamping plate 10 to move stably with the slide rod 11. The structure is simple. Then, the fastening bolt 24 is rotated to thread-fix the support plate 18. Then, the threaded rod 19 is rotated, which drives the moving plate 20 to move. The moving plate 20 moves the support plate 21, which in turn moves the main body of the module assembly 1. The module assembly body 1 is moved closer to the bristles of the cleaning brush ventilation. Then, the operation panel 9 is moved, which drives the rotating shaft 4 to move. The rotating shaft 4 drives the slide plate 3 to slide in the channel. When the slide plate 3 moves, it drives the limiting plate 15 to move. The limiting plate 15 is L-shaped, which limits the front and rear sides of the slide plate 3, thus locking the slide plate 3 in the channel. This allows the slide plate 3 to move stably in the channel, preventing it from falling out and improving its stability. Combined with the meshing of the gear 5 and the toothed plate 6, the cleaning brush cylinder 8 rotates when the rotating shaft 4 moves. The rotating cleaning brush cylinder 8 cleans the dust on the module assembly body 1, thus ensuring the cleanliness of the module assembly body 1. The base plate 16 is used to fix the silicone pad 17 to the bottom of the bracket 2. Combined with the function of the silicone pad 17, the friction between the bracket 2 and the table is increased, improving the stability and firmness of the bracket 2. Combined with the function of the sponge sleeve, the horizontal part of the operation panel 9 is wrapped, thus improving the comfort of the operator's hands.
