Description
Technical Field
[0001] The present application relates to the technical field of car wash machines, and in particular to a position limiting protection device for a car wash machine. Background Art
[0002] In the modern car washing industry, car washing machines, as an efficient and convenient car washing equipment, have been widely used in various car washing places.
[0003] However, in actual use, existing car washers, when moving along a pre-set track to wash cars, cannot stop running in time if an object or person accidentally blocks their path. Due to the lack of effective position-limiting protection devices, the car washers may continue to move and collide with the obstructing object, potentially damaging the machine itself and, more importantly, causing serious injury to the obstructed object or person.
[0004] Specifically, because car washers typically have a certain mass and speed, the impact force generated during movement is considerable. If this impact force acts directly on a person, it can cause serious bodily injury; if it acts on fragile or valuable items, it can damage or break them. Therefore, how to effectively prevent car washers from colliding with obstructions during movement has become a pressing technical issue.
[0005] In view of the above problems, a car washing machine limiting protection device is now designed. Utility Model Content
[0006] An embodiment of the present application provides a position limiting protection device for a car washing machine to solve the problem in the related art that a car washing machine moves on a preset track to perform a car washing operation, and its travel route is accidentally blocked by objects or people, and the operation cannot be stopped in time.
[0007] In a first aspect, a car washing machine limit protection device is provided, comprising:
[0008] A support frame and a car washing machine body, wherein the car washing machine body has a driving part, and a plurality of mounting plates are provided on the car washing machine body. A stable box is provided at the bottom of the mounting plate. Inside the stable box, a sensor sheet is slidably provided inside the stable box. A photoelectric proximity switch is embedded in the stable box and is located below the sensor sheet.
[0009] Two lifting sliding holes are relatively formed on the stable box, and a safety ring located on the outside of the stable box is slidably arranged between the two lifting sliding holes. Both ends of the safety ring pass through the lifting sliding holes and are hung on the two ends of the sensor plate. The safety ring is sleeved on the outside of the car washing machine body, and the photoelectric proximity switch is electrically connected to the driving part. When the safety ring shakes and drives the sensor plate to slide, the photoelectric proximity switch receives a signal to control the driving part to stop.
[0010] In some embodiments, a plurality of tracks are provided on the support frame, the car washing machine body is slidably provided on the tracks, and the driving unit is used to drive the car washing machine body to move along the height direction or the length direction of the support frame.
[0011] In some embodiments, the stable box includes a box body and a box cover, the mounting plate is disposed on the box body, and the box body and the box cover are connected by bolts;
[0012] The lifting sliding holes are provided on the box body and the box cover, and the lifting sliding holes at adjacent positions on the box body and the box cover are aligned with each other and communicated with each other.
[0013] In some embodiments, the top of the box body is open, and two arc-shaped sliding surfaces are formed opposite to each other on the top of the box body, and the sensor piece is slidably disposed on the arc-shaped sliding surfaces.
[0014] In some embodiments, the box cover is rectangular, an opening is provided at the bottom of the box cover, the box cover is sleeved on the box body, and two U-shaped holes are provided on the box cover in opposite directions.
[0015] In some embodiments, the sensing piece is cross-shaped, and both ends of the sensing piece are relatively slidably disposed on an arc-shaped sliding surface and extend into the U-shaped hole;

The two ends of the safety ring are hung inside the corresponding hanging holes, and the two ends of the safety ring extend to the outside of the hanging holes and tilt toward the side away from the induction sheet.
[0017] The present invention provides a car washer position limit protection device. By combining a mounting plate, a stabilizing box, a sensor plate, a photoelectric proximity switch, and a safety ring, the device effectively detects and responds to obstructions in the washer's path, promptly stopping the machine to avoid collisions and protect personnel and objects. Furthermore, the device features a relatively simple structure and utilizes mature technical components, such as the photoelectric proximity switch, making it easy to manufacture and install, reducing costs.
[0018] By using a photoelectric proximity switch as the detection element, it has high sensitivity and fast response speed. At the same time, the connection between the safety ring and the sensor plate ensures that the device can stably transmit the shaking signal when subjected to external forces, improving the reliability of the device.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0027] An embodiment of the present application provides a position limiting protection device for a car washing machine, which can solve the problem in the related art that a car washing machine moves on a preset track to perform a car washing operation, and its travel route is accidentally blocked by objects or people, and the operation cannot be stopped in time.
[0028] See also Figure 1-Figure 3A car washing machine limit protection device includes: a support frame 1 and a car washing machine body 2, the car washing machine body 2 has a driving part 21, a plurality of mounting plates 4 are provided on the car washing machine body 2, and a plurality of mounting plates 3 are distributed along the length of the car washing machine body 2. A stable box 5 is provided at the bottom of the mounting plate 4, and a sensor sheet 6 is slidably provided inside the stable box 5. A photoelectric proximity switch 7 is embedded in the stable box 5 and is located below the sensor sheet 6;
[0029] Two lifting sliding holes 8 are relatively provided on the stable box 5, and a safety ring 9 is slidingly provided between the two lifting sliding holes 8 and located on the outside of the stable box 5. Both ends of the safety ring 9 pass through the lifting sliding holes 8 and are hung with the two ends of the sensor plate 6. The safety ring 9 is sleeved on the outside of the car washing machine body 2, and the photoelectric proximity switch 7 is electrically connected to the driving part 21. When the safety ring 9 shakes and drives the sensor plate 6 to slide, the photoelectric proximity switch 7 receives a signal to control the driving part 21 to stop.
[0030] When the car washer body 2 moves along the preset track on the support frame 1 to perform a car washing operation, the safety ring 9 is sleeved on the outer side of the car washer body 2 and moves with the movement of the car washer body 2. The two ends of the safety ring 9 are hooked to the two ends of the induction plate 6 through the lifting slide holes 8, so that the safety ring 9 can stably support and drive the induction plate 6 to slide inside the stabilizing box 5.
[0031] Under normal circumstances, the sensor plate 6 is located above the photoelectric proximity switch 7 and maintains a certain distance. The photoelectric proximity switch 7 does not send a stop signal, and the drive unit 21 of the car washer body 2 continues to operate, so that the car washer body 2 keeps moving. However, if the travel path of the car washer body 2 is accidentally blocked by an object or a person, causing the safety ring 9 to shake due to external force, this shaking will be transmitted to the sensor plate 6, causing it to slide along the inside of the stabilizing box 5, thereby changing its relative position with the photoelectric proximity switch 7.
[0032] When the sensor sheet 6 slides into the sensing range of the photoelectric proximity switch 7, the photoelectric proximity switch 7 immediately receives the signal and triggers the control logic to send a stop signal to the drive unit 21. After receiving the stop signal, the drive unit 21 immediately stops working, causing the car washing machine body 2 to stop moving, thereby avoiding collision with obstructions.
[0033] The car washing machine limit protection device can effectively detect and respond to obstructions on the car washing machine's route, and stop the movement of the car washing machine in time, thereby avoiding collision with the obstructions and protecting the safety of people and objects.
[0034] The device is mainly composed of a support frame, a car washer body, a mounting plate, a stabilizing box, a sensor plate, a photoelectric proximity switch, and a safety ring. Its structure is relatively simple and easy to manufacture and install. At the same time, the use of mature technical components such as photoelectric proximity switches reduces costs.
[0035] The device uses a photoelectric proximity switch as a detection element, which features high sensitivity and fast response. Furthermore, the connection between the safety ring and the sensor plate ensures that the device can stably transmit shaking signals when subjected to external forces, thus improving its reliability.
[0036] The device can be adapted to different types of car wash machine bodies and support frames by simply adjusting the position and number of mounting plates according to actual needs. Furthermore, the sensing range and sensitivity of the photoelectric proximity switch can be adjusted as needed to suit different application scenarios.
[0037] It should be noted that a plurality of tracks are provided on the support frame 1 , and the car washing machine body 2 is slidably provided on the tracks. The driving part 21 is used to drive the car washing machine body 2 to move along the height direction or the length direction of the support frame 1 .
[0038] The car washer body 2 slides on pre-set tracks on the support frame 1 via pulleys or sliding devices at its bottom. These tracks can be arranged along the height or length of the support frame 1 to meet the needs of different car washing scenarios. The drive unit 21 provides power to the car washer body 2, allowing it to move smoothly along the tracks.
[0039] The main function of the driving part 21 is to drive the car washing machine body 2 to move along the height or length of the support frame 1. The common driving part 21 can be a gantry two-axis linear module or a gantry three-axis linear module, which is the existing technology and will not be described here.
[0040] Specifically, such as Figure 2 and Figure 3 As shown, the stable box 5 in this embodiment includes a box body 51 and a box cover 52. The mounting plate 4 is mounted on the box body 51, and the box body 51 and the box cover 52 are connected by bolts. The lifting slide holes 8 are provided in the box body 51 and the box cover 52. The lifting slide holes 8 in adjacent positions on the box body 51 and the box cover 52 are aligned and connected. The lifting slide holes 8 on the box cover 52 are open at the bottom, while the lifting slide holes on the box body 51 are L-shaped and extend to the bottom of the box body 51.
[0041] The top of the box body 51 is open to facilitate installation and maintenance of internal components such as the sensor plate 6. Two opposing lifting holes 8 are provided on the side walls of the box body 51. These L-shaped lifting holes 8 extend from the side walls to the bottom of the box body 51, providing the necessary space for the safety ring 9 and the sensor plate 6 to slide.
[0042] The lid 52 seals the opening of the box body 51, protecting the internal components from external environmental damage such as dust and moisture. Lid 52 also has sliding holes 8 aligned with and connected to the sliding holes 8 in the box body 51. These sliding holes 8 are open on lid 52 to ensure smooth sliding of safety ring 9 and sensor plate 6. Lid 52 is connected to the box body 51 via bolts and other fasteners, forming a closed and rigid unit.
[0043] The mounting plate 4 is arranged on the top or side wall of the box body 51 for firmly mounting the stable box 5 on the car washer body 2. The mounting plate 4 is usually provided with connecting structures such as bolt holes or buckles to facilitate fixed connection with the car washer body 2.
[0044] The lifting slide hole 8 is aligned and connected on the box body 51 and the box cover 52, providing the necessary space and guidance for the sliding of the safety ring 9 and the sensor plate 6, ensuring that the safety ring 9 and the sensor plate 6 can slide smoothly and stably when subjected to external force, thereby accurately triggering the photoelectric proximity switch 7 and stopping the movement of the car washing machine body 2.
[0045] Furthermore, if Figure 3 and Figure 4 As shown, the top of the box body 51 is open, and two arc-shaped sliding surfaces 3 are oppositely provided on the top of the box body 51 , and the sensor sheet 6 is slidably arranged on the arc-shaped sliding surfaces 3 .
[0046] The curved sliding surface 3 provides a clear and stable sliding track for the sensor plate 6. When the safety ring 9 is shaken by external forces, it drives the sensor plate 6 to slide along the curved sliding surface 3, ensuring that the sensor plate 6 can move in a predictable and controllable manner, thereby accurately triggering the photoelectric proximity switch 7.
[0047] The curved sliding surface 3 not only helps the sensing piece 6 to slide smoothly, but also enhances the stability of the entire device. Since the curved sliding surface 3 has a certain curvature, it can better support the sensing piece 6 and prevent it from tilting or getting stuck during the sliding process.
[0048] It should be noted that the curvature of the curved sliding surface 3 can be optimized according to actual needs. By adjusting the curvature and length of the curved sliding surface 3, it is possible to ensure that the sensing piece 6 can cover the sensing area of the photoelectric proximity switch 7 during the sliding process, thereby triggering the stop signal. At the same time, it can also prevent the sensing piece 6 from unnecessary collision or friction with other parts of the box body 51 during the sliding process.
[0049] Further, such as Figure 2 and Figure 5As shown, the box cover 52 is rectangular, and an opening is provided at the bottom of the box cover 52 . The box cover 52 is sleeved on the box body 51 , and two U-shaped holes 521 are provided on the box cover 52 in opposite directions.
[0050] The box cover 52 is designed to be rectangular in shape, and an opening is provided at its bottom so as to be sleeved on the box body 51. The shape and size of the opening of the box cover 52 match the top of the box body 51, ensuring that the box cover 52 can tightly cover the top opening of the box body 51.
[0051] In addition, two U-shaped holes 521 are formed on the box cover 52 . The U-shaped holes 521 correspond to the arc-shaped sliding surface 3 on the box body 51 in the vertical direction and provide additional space for the sliding of the sensor plate 6 .
[0052] In one embodiment, the sensing piece 6 is cross-shaped, and the two ends of the sensing piece 6 are relatively slidably arranged on the arc-shaped sliding surface 3 and extend into the U-shaped hole 521; the other two ends of the sensing piece 6 are inclined downward and have hanging holes, and the two ends of the safety ring 9 are hung inside the corresponding hanging holes, and the two ends of the safety ring 9 extend to the outside of the hanging hole and tilt toward the side away from the sensing piece 6.
[0053] The sensing piece 6 is in a cross shape, so that the sensing piece 6 can cover two curved sliding surfaces 3 at the same time and slide along them. Specifically, the two ends of the sensing piece 6 are relatively slidably arranged on the curved sliding surface 3 and extend into the U-shaped hole 521. In this way, when the safety ring 9 is shaken by external force, it will drive the sensing piece 6 to slide along the curved sliding surface 3 and the U-shaped hole 521 through the hanging hole.
[0054] In addition, the other two ends of the induction plate 6 are tilted downward and are provided with hanging holes, which are used to hang the two ends of the safety ring 9 .
[0055] After the two ends of the safety ring 9 are hung in the corresponding hanging holes, they will tilt toward the side away from the sensing piece 6. This design not only ensures a firm connection between the safety ring 9 and the sensing piece 6, but also enables the safety ring 9 to more effectively drive the sensing piece 6 to slide when subjected to external force.
