[0045] Figure 3 is Figure 2 a partial enlarged view of Figure 4 is Figure 3 a sectional view taken along line A-A of Figure 5 is Figure 3 a sectional view taken along line B-B of

[0046] The safety protection device 100 of the side brush of the car washing machine of the present invention is connected to a car washing machine. The car washing machine includes a frame 10 and a cross beam 20. The cross beam 20 is horizontally connected to the frame 10, and the side brush of the car washing machine is connected to the cross beam 20. The frame 10 is connected to, for example, the support structure of the car washing machine or is itself the support structure of the car washing machine, which is not shown in the drawings of the present invention. The side brush of the car washing machine (not shown in the drawings) can move along the cross beam 20 and is a working part for washing the vehicle.

[0047] The end of the cross beam 20 is rotatably connected to the frame 10. The safety protection device 100 includes a support rod 110, an elastic resetting member 120 and a swing arm 130. The support rod 110 is vertically connected to the frame 10. The elastic resetting member 120 is sleeved on the support rod 110. The support rod 110 is arranged in a direction substantially perpendicular to the cross beam 20. AsFigure 2 and Figure 3 As shown in Figure 3 , the swing arm 130 includes a first end 130a and a second end 130b. The first end 130a is connected to the cross beam 20, and the second end 130b is connected to the middle part of the elastic reset member 120. When the cross beam 20 is driven by an impact to swing the swing arm 130, the elastic reset member 120 drives the swing arm 130 to reset through elastic force.

[0048] The safety protection device 100 of the side brush of the car washing machine according to the present invention can buffer and limit the swing of the swing arm 130 to a certain extent by setting the elastic member 120, so that the cross beam 20 swings smoothly. For example, if the cross beam 20 is rotated in the X direction as shown in the figure under the impact, the cross beam 20 drives the second end 130b of the swing arm 130 connected to the middle part of the elastic reset member 120 to tilt upward, compressing the upper half of the elastic reset member 120 and stretching the lower half of the elastic reset member 120. Under the action of the downward elastic reset force of the elastic reset member 120, the second end 130b of the swing arm 130 rotates to be buffered and can quickly reset, avoiding damage to the structure of the car washing system and the vehicle being washed.

[0049] Preferably, there are two safety protection devices 100, which are respectively connected to the left and right ends of the cross beam 20, that is, both ends of the cross beam 20 are rotatably connected to the frames 10 on both sides. For example, the left and right ends of the cross beam 20 are installed on the frame 10 through bearing seats. When the side brush swings in the reverse direction under the action of an external force, the cross beam 20 and the swing arm 130 can swing within a certain range around the swing axis in the bearing seat. When the cross beam 20 is impacted, the two safety protection devices 100 on the left and right play a buffering role at the same time.

[0050] The upper and lower ends of the support rod 110 are installed on the frame 10 of the car washing machine through fixing seats, for example. In an embodiment of the present invention, the elastic reset member 120 includes an upper elastic compression spring 121 and a lower elastic compression spring 122. The upper elastic compression spring 121 and the lower elastic compression spring 122 are respectively sleeved outside the support rod 110, and the second end 130b of the swing arm 130 is movably sleeved on the support rod 110 between the upper elastic compression spring 121 and the lower elastic compression spring 122. When the cross beam 20 is rotated in the X direction as shown in the figure under the impact, the cross beam 20 drives the second end 130b of the swing arm 130 to lift upward, compressing the upper elastic compression spring 121. The upper elastic compression spring 121 rebounds and presses down the second end 130b of the swing arm 130 to make it return to its original position. The swing arm 130 drives the cross beam 20 at the first end 130a to rotate and reset in the reverse direction of the X direction. When the cross beam 20 is rotated in the reverse direction of the X direction as shown in the figure under the impact, the cross beam 20 drives the second end 130b of the swing arm 130 to press down, compressing the lower elastic compression spring 122. The lower elastic compression spring 122 rebounds and lifts the second end 130b of the swing arm 130 to make it return to its original position. The swing arm 130 drives the cross beam 20 at the first end 130a to rotate and reset in the X direction.

[0051] In an embodiment of the present invention, it further includes an upper adjusting nut 140 and a lower adjusting nut 150. The support rod 110 is a screw rod. The upper adjusting nut 140 is threadedly connected to the support rod 110 and is located at the upper end of the upper elastic compression spring 121. The lower adjusting nut 150 is threadedly connected to the support rod 110 and is located at the lower end of the lower elastic compression spring 122. That is, the top of the upper elastic compression spring 121 abuts against the upper adjusting nut 140, the bottom of the upper elastic compression spring 121 abuts against the second end 130b of the swing arm 130, the top of the lower elastic compression spring 122 abuts against the second end 130b of the swing arm 130, the bottom of the lower elastic compression spring 122 abuts against the lower adjusting nut 150. The upper adjusting nut 140, the upper elastic compression spring 121, the second end 130b of the swing arm 130, the lower elastic compression spring 122 and the lower adjusting nut 150 are sequentially arranged on the support rod 110 from top to bottom. Both ends of the support rod 110 are installed on the frame 10 of the car washer through fixed seats. During the car washing process, under the buffering action of the upper elastic compression spring 121 and the lower elastic compression spring 122, the swing of the cross beam 20 will be more stable. By adjusting the positions of the upper adjusting nut 140 and the lower adjusting nut 150 on the support rod 110, the initial deformation amounts of the upper elastic compression spring 121 and the lower elastic compression spring 122 can be set, and further the resilience forces of the upper elastic compression spring 121 and the lower elastic compression spring 122 when being compressed and rebounding can be adjusted to achieve the required buffering capacity effect.

[0052] The swing arm 130 can be an integral part. The first end 130a of the swing arm 130 is a plane, and is welded or riveted or screwed to the end of the cross beam 20. The second end 130b is formed with a clamping opening for the support rod 110 to pass through, and the opening of the clamping opening is closed by a connecting member 160.

[0053] In addition, the swing arm 130 can be made into a split part, including a connecting plate 131 and an h-shaped rod 132 connected to the connecting plate 131. The h-shaped opening of the h-shaped rod 132 forms the second end 130b. The connecting plate 131 is connected to the end of the cross beam 20 in a plate shape, and the cross beam 20 is rotatably connected to the frame 10 through the connecting plate 131. Among them, one side of the h-shaped rod 132 is fixedly connected to the connecting plate 131, for example, by bolts. Making the swing arm 130 into a split part is more conducive to processing and installation.

[0054] In an embodiment of the present invention, it further includes a displacement detection and alarm component 170 for detecting the swing range of the cross beam 20. The displacement detection and alarm component 170 includes a detection unit and an alarm unit. When the detection unit detects that the swing angle of the cross beam 20 exceeds a threshold value, the alarm unit gives an alarm. The displacement detection and alarm component 170 is, for example, a group, and is installed at a position at one end of the cross beam 20.

[0055] Among them, the detection unit includes an induction plate 171 and an inductor 172 respectively connected to the cross beam 20 and the frame 10. In this embodiment, the inductor 172 is connected to the frame 10, and the induction plate 171 is connected to the cross beam 20. In other embodiments, the inductor 172 may be connected to the cross beam 20, while the induction plate 171 is connected to the frame 10.

[0056] The induction plate 171 is fixedly installed at the top of the left end or the right end of the cross beam 20 and close to the swing arm 130. An inductor 172 is installed at the corresponding position on the frame 10. Whether the cross beam 20 swings beyond the threshold is judged by the relative position relationship between the inductor 172 and the induction plate 171. When the side brush of the car washer encounters a large resistance, it will drive the cross beam 20 to swing at a large angle. At this time, the induction plate 171 fixedly connected to the cross beam 20 will be misaligned with the inductor 172 installed on the frame 20. When it exceeds a set threshold range, the controller connected to the inductor 172 issues an alarm signal and at the same time controls the car washer to stop running to achieve the purpose of safety protection. After the troubleshooting is completed, it can be directly reset. Among them, the inductor 172 can be, for example, a proximity switch.

[0057] In other embodiments, the detection unit includes, for example, an angle inductor for measuring the swing angle of the cross beam 20, and the swing angle of the cross beam 20 is detected by the angle inductor. The shift detection and alarm assembly 170 is a safety detection mechanism. For example, when the detected swing exceeds ±4.5°, an alarm is triggered.

[0058] Of course, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention. However, these corresponding changes and deformations should all fall within the protection scope of the claims attached to the present invention.
