Description

Technical Field

[0001] This utility model relates to the field of wire-controlled chassis technology, and in particular to a wire-controlled chassis sensor device with a retractable controller. Background Technology

[0002] With the rapid development of industrial automation and intelligent control technologies, drive-by-wire chassis systems are widely used in robotics, AGVs (Automated Guided Vehicles), and intelligent logistics equipment. Sensors, as core detection components, directly affect the system's positioning accuracy and operational stability. However, traditional sensors are typically fixed directly to exposed locations on the chassis, making them susceptible to impacts, dust, and moisture corrosion under complex working conditions, leading to decreased detection accuracy or even damage. Furthermore, conventional installation methods require the disassembly of numerous structural components for sensor maintenance or replacement, making the process cumbersome and time-consuming. Therefore, there is an urgent need for a drive-by-wire chassis sensor device that can house the controller, enabling rapid sensor storage, protection, and convenient maintenance while maintaining detection accuracy.

[0003] Currently, the installation methods for sensors on existing wire-controlled chassis mainly employ direct bolt fixing or snap-on mounting structures. Some solutions suspend the sensor on the side of the chassis using rigid brackets and protective covers to reduce external impact; others use sliding rail structures to achieve limited sensor displacement, facilitating manual adjustment of the detection angle. Regarding the driving method, traditional technologies mostly rely on manual push-pull or simple spring mechanisms to adjust the sensor position. A few high-end devices use electric actuators, but these have complex overall structures and occupy a large amount of space. Furthermore, sensor disassembly and assembly typically require tools to loosen bolts or release snaps, involving numerous steps and failing to meet the needs of efficient maintenance.

[0004] However, traditional fixed or simple sliding sensors are difficult to automate for storage and precise deployment. Maintenance requires repeated manual disassembly and reassembly of peripheral components, which is not only inefficient but also prone to causing sensor calibration failure or mechanical damage due to improper operation. This problem restricts the convenience of equipment maintenance, especially in intensive operations or high-frequency maintenance scenarios, further increasing downtime and maintenance costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wire-controlled chassis sensor device with a retractable controller, which aims to improve the problem that traditional fixed or simple sliding structure sensors are difficult to automate and accurately deploy, and require repeated manual disassembly and assembly of peripheral components during maintenance, which is not only inefficient, but also prone to sensor calibration failure or mechanical damage due to improper operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wire-controlled chassis sensor device that can house a controller, comprising a chassis frame, wherein a fixing frame is fixedly connected to the outer wall of the chassis frame, and a propulsion component is provided inside the fixing frame;

[0007] The propulsion assembly includes a push plate, a guide plate fixedly connected to one end of the push plate, a slide plate fixedly connected to the outer wall of the guide plate, a fixing block 1 attached to the inner wall of the guide plate, a chain fixedly connected to the outer wall of the fixing block 1, a fixing column fixedly connected to the outer wall of the fixing frame, a sprocket 1 rotatably connected to the outer wall of the fixing column, a sprocket 2 provided on the outer wall of the fixing frame, the sprocket 2 and the sprocket 1 respectively meshing at both ends of the chain, a motor fixedly connected to the inner wall of the fixing frame, and the output end of the motor fixedly connected to one end of the fixing column.

[0008] Furthermore, a slider is slidably connected to the inner wall of the fixed frame, a placement plate is fixedly connected to the outer wall of the slider, a fixed plate is attached to the inner wall of the placement plate, a sensor body is fixedly connected to the outer wall of the fixed plate, and an installation assembly is provided on the inner wall of the fixed plate.

[0009] Furthermore, the mounting assembly includes a rotating plate, the outer wall of which is slidably connected to the inner wall of a fixed plate. A fixed rod is rotatably connected inside the rotating plate, and a fixed block is fixedly connected to the outer wall of the fixed rod. The placement plate is threadedly connected to the fixed rod, and a handle is fixedly connected to one end of the fixed rod.

[0010] Furthermore, the handle is disposed on one side of the outer wall of the rotating plate, and the outer wall of the rotating plate is slidably connected to the inside of the placement plate.

[0011] Furthermore, the second fixing block is fixedly connected to the outer wall of the placement plate, and the handle is attached to the outer wall of the first fixing rod.

[0012] Furthermore, the outer wall of one end of the fixing rod is provided with an external thread that matches the internal thread of the placement plate.

[0013] Furthermore, the lower surface of the placement plate is slidably connected to the inner wall of the fixed frame, and the sensor body is disposed inside the placement plate.

[0014] Furthermore, the guide plate is disposed outside the fixed frame, and the chain is disposed outside the fixed frame.

[0015] Furthermore, the fixed frame has a sliding groove inside for guiding the push plate to slide.

[0016] Furthermore, the outer wall of the push plate is slidably connected inside the fixed frame, and one side of the outer wall of the push plate is fixedly connected to the placement plate.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting a cooperative structure between the push component and the fixed frame, the automatic push-out and storage function of the sensor body can be realized, which effectively solves the problem of inconvenient maintenance of traditional chassis sensors. The motor drives the sprocket and chain mechanism to drive the push plate to move, so that the placement plate moves smoothly out along the slider guide. This not only improves the operating efficiency, but also ensures the motion accuracy through mechanical linkage. At the same time, the sliding groove design inside the fixed frame avoids the shaking of the parts, which significantly improves the convenience and reliability of equipment maintenance.

[0019] 2. In this utility model, the sensor body can be quickly disassembled and assembled by rotating the handle, which is more efficient than the traditional bolt fixing method. The cooperation structure between the rotating plate and the fixing rod realizes a double locking function. The threaded connection between the handle and the fixing rod ensures the installation stability. Furthermore, the sliding cooperation structure between the placement plate and the fixing frame allows the sensor to be completely stored inside the equipment, which not only protects the precision sensor from external impacts but also optimizes the overall space utilization.

[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 1-4 The present invention provides an embodiment of a wire-controlled chassis sensor device that can house a controller, including a chassis frame 1, which provides support and installation foundation for the entire device. A fixed frame 2 is fixedly connected to the outer wall of the chassis frame 1, and a propulsion component is provided inside the fixed frame 2.

[0030] The propulsion assembly includes a push plate 14 that pushes the placement plate 4 to achieve telescopic movement. A guide plate 12 is fixedly connected to one end of the push plate 14, converting the movement of the chain 9 into linear motion. A slide plate 13 is fixedly connected to the outer wall of the guide plate 12, which slides within the chassis frame 1 to guide the movement. A fixing block 11 is attached to the inner wall of the guide plate 12, connecting the chain 9 and transmitting the movement to the guide plate 12. The chain 9 is fixedly connected to the outer wall of the fixing block 11, transmitting the power of the motor 15 to the fixing block 11. A fixing column 7 is fixedly connected to the outer wall of the fixing frame 2, providing rotational support for the sprocket 8. The sprocket 8 is rotatably connected to the outer wall of the fixing column 7, meshing with the chain 9 to transmit power. A second sprocket 10 is provided on the outer wall of the fixing frame 2, connected to the output end of the motor 15 to drive the chain 9. The second sprocket 10 and the first sprocket 8 mesh at both ends of the chain 9 respectively. The motor 15 is fixedly connected to the inner wall of the fixing frame 2, providing power to the entire propulsion assembly. The output end of the motor 15 is fixedly connected to one end of the fixing column 7.

[0031] Specifically, firstly, the motor 15 is started. The output end of the motor 15 drives the second sprocket 10 to rotate around the fixed column 7. Since the second sprocket 10 meshes with the chain 9 and the first sprocket 8, the chain 9 drives the first fixed block 11 to move along a predetermined trajectory. The movement of the first fixed block 11 pushes the guide plate 12. The guide plate 12 slides in the chassis frame 1 through the slide plate 13, and at the same time drives the push plate 14 to move in a straight line. The push plate 14 pushes the placement plate 4 to move outward along the inner wall of the fixed frame 2. At this time, the slider 3 slides in the fixed frame 2, providing stable motion guidance for the placement plate 4, and finally realizes the complete ejection of the placement plate 4 from the inside of the fixed frame 2.

[0032] Reference Figure 5 and Figure 6A slider 3 is slidably connected to the inner wall of the fixed frame 2, providing a sliding guide for the placement plate 4. The placement plate 4 is fixedly connected to the outer wall of the slider 3, used to support and fix the sensor body 5. A fixed plate 6 is attached to the inner wall of the placement plate 4, used to fix the sensor body 5. The sensor body 5 is fixedly connected to the outer wall of the fixed plate 6. An installation assembly is provided on the inner wall of the fixed plate 6, including a rotating plate 18, which locks and releases the fixed plate 6 by rotation. The outer wall of the rotating plate 18 is slidably connected to the inner wall of the fixed plate 6. A fixing rod 17 is rotatably connected inside the rotating plate 18. A fixing block 16 is fixedly connected to the outer wall of the fixing rod 17, providing an installation fulcrum for the fixing rod 17. A fixing rod 19 is threadedly connected inside the placement plate 4, which presses the rotating plate 18 through the threaded connection. One end of the fixed rod 19 is fixedly connected to a handle 20, providing an operating point for the operator to apply force to rotate the second fixed rod 19. The handle 20 is located on one side of the outer wall of the rotating plate 18, and the outer wall of the rotating plate 18 is slidably connected to the inside of the placement plate 4. The second fixed block 16 is fixedly connected to the outer wall of the placement plate 4. The handle 20 is attached to the outer wall of the first fixed rod 17. One end of the outer wall of the second fixed rod 19 is provided with an external thread that matches the internal thread of the placement plate 4. The lower surface of the placement plate 4 is slidably connected to the inner wall of the fixed frame 2. The sensor body 5 is located inside the placement plate 4. The guide plate 12 is located outside the fixed frame 2. The chain 9 is located outside the fixed frame 2. The fixed frame 2 has a groove for sliding guide of the push plate 14. The outer wall of the push plate 14 is slidably connected to the inside of the fixed frame 2. One side of the outer wall of the push plate 14 is fixedly connected to the placement plate 4.

[0033] Specifically, the operator rotates handle 20, causing the second fixing rod 19 to rotate. When handle 20 rotates to a position parallel to the rotating plate 18, the rotating plate 18 can rotate around the first fixing rod 17. Continue the operation to make the rotating plate 18 break free from the constraint of the inner wall of the fixing plate 6, and the sensor body 5 can be removed from the placement plate 4. During installation, rotate handle 20 in the opposite direction, and the rotating plate 18 will be reset and pressed against the fixing plate 6 through the threaded connection of the second fixing rod 19, thus completing the quick fixation of the sensor body 5. The entire disassembly and assembly process does not require auxiliary tools and is simple and reliable to operate.

[0034] Working principle: When the wire-controlled chassis sensor device with retractable controller needs to be used, firstly, when the sensor body 5 needs to be repaired, the motor 15 is started. The output end of the motor 15 drives the second sprocket 10 to rotate. At this time, the second sprocket 10 rotates along the outer wall of the fixed column 7. Since the second sprocket 10 is engaged with the chain 9 and the first sprocket 8, the rotation of the second sprocket 10 will drive the chain 9 and the fixed block 11 fixed on the outer wall of the chain 9 to move. At this time, the movement of the fixed block 11 will drive the guide plate 12 to move. The movement of the guide plate 12 will drive the slide plate 13 to slide on the inner wall of the chassis frame 1. Then, the movement of the fixed block 11 will drive the push plate 14 to push the placement plate 4 to move, thereby realizing the push of the placement plate 4 out of the fixed frame 2. During this process, the slider 3 will slide along the inner wall of the fixed frame 2 to provide guidance for the movement of the placement plate 4.

[0035] In addition, when it is necessary to disassemble the sensor body 5, the fixed rod 19 is rotated by turning the handle 20. When the handle 20 is rotated to be parallel to the rotating plate 18, the rotating plate 18 is rotated along the outer wall of the fixed rod 17. When the rotating plate 18 is separated from the inner wall of the fixed plate 6, the sensor body 5 can be quickly disassembled. When installing the sensor body 5, the handle 20 is simply turned in the opposite direction to fix the sensor body 5.

[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.
