Description

Technical Field

[0001] The utility model relates to the technical field of car washing machines, in particular to an anti-collision mechanism for a car washing machine. Background Art

[0002] Common automatic car washes on the market are categorized as contact-based brush washers and contactless washers. Contactless washers require the car to be parked within the wash frame, which then moves along tracks to clean the car. To minimize space usage and the force of the wash fluid spraying onto the car body, the frame is typically not particularly large.

[0003] In the prior art, there is a new type of double-arm contactless car washing machine with publication number: CN213168010U, which includes a car washing machine frame, a pump box and a water inlet electrical pipeline. A pump box is provided on the outside of the car washing machine frame, and a car washing machine crane body is provided on the top of the car washing machine frame. The top of the car washing machine crane body is connected to a water inlet electrical drag chain... The front end of the crane body frame is fixed to the front cover of the car washing machine body, and the rear end of the crane body frame is fixed to the rear cover of the car washing machine body. Both sides of the bottom end of the crane body frame are provided with a car washing arm high-pressure water spray pipe, a car washing arm wipe-free foam spray pipe, a car washing arm external protective cover and a fantasy foam spray pipe.

[0004] When the above equipment is in use, there is a possibility that the vehicle is improperly parked and the frame of the car wash machine may scratch the vehicle body while moving, causing damage to the vehicle body and the car wash machine. Utility Model Content

[0005] (1) Technical problems solved

[0006] In order to solve the above problems in the prior art, the utility model provides a car washing machine anti-collision mechanism, which can protect the car washing machine frame and the vehicle body.

[0007] (2) Technical solution

[0008] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0009] A car washer anti-collision mechanism includes a running track and a car washer frame. The car washer frame is movable on the running track. A protective mechanism is provided below the inner wall of the car washer frame. The protective mechanism includes a folding torsion spring bracket fixedly mounted below the inner wall of the car washer frame, a fixed rod fixedly mounted on the folding torsion spring bracket, a protective sleeve rotatably mounted on the fixed rod, and a position sensor used in conjunction with the folding torsion spring bracket. The protective mechanism can protect the car washer frame and the vehicle body.

[0010] Preferably, the torsion spring folding bracket includes a first folding part fixedly connected to the car washing machine frame, a second folding part rotatably connected to the first folding part through a rotating shaft and a torsion spring, and a detection part used in conjunction with a position sensor on the top of the second folding part, the detection part is fixedly installed above the second folding part, and the fixing rod is fixedly installed at the bottom of the second folding part.

[0011] Preferably, two protective mechanisms are provided, which are respectively located on the front and back inner walls of the car washing machine frame.

[0012] (3) Beneficial effects

[0013] The utility model provides an anti-collision mechanism for a car washing machine. It has the following beneficial effects:

[0014] (1) The protective sleeve is made of flexible material. When the car washing machine frame moves, the protective sleeve can protect the car body and avoid hard contact.

[0015] (2) If the force exerted by the vehicle body against the protective sleeve is large, the fixing rod drives the torsion spring folding bracket to rotate, and the position sensor detects the change in the position of the torsion spring folding bracket, and cooperates with the alarm system to sound an alarm and shut down the machine.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-3As shown, the anti-collision mechanism for a car washer in this embodiment includes a running track 1 and a car washer frame 2. The car washer frame 2 is movable on the running track 1. A protective mechanism 3 is provided below the inner wall of the car washer frame 2. The protective mechanism 3 includes a folding torsion spring bracket 301 fixedly mounted below the inner wall of the car washer frame 2, a fixed rod 302 fixedly mounted on the folding torsion spring bracket 301, a protective sleeve 303 rotatably mounted on the fixed rod 302, and a position sensor 304 used in conjunction with the folding torsion spring bracket 301. The protective sleeve 303 can protect the vehicle body and the car washer. The position sensor 304 can detect the status of the folding torsion spring bracket 301 and can cooperate with the alarm system of the car washer to issue an alarm.

[0022] Furthermore, the torsion spring folding bracket 301 includes a first folding portion 3001 fixedly connected to the car washer frame 2, a second folding portion 3002 rotatably connected to the first folding portion 3001 via a rotating shaft and a torsion spring, and a detection portion 3003 at the top of the second folding portion 3002 that cooperates with a position sensor 304. The detection portion 3003 is fixedly mounted above the second folding portion 3002, and the fixing rod 302 is fixedly mounted at the bottom of the second folding portion 3002. When the force exerted by the vehicle body against the protective sleeve 303 is relatively large, the fixing rod 302 drives the second folding portion 3002 to rotate relative to the first folding portion 3001. The detection portion 3003 rotates along with the second folding portion 3002, and the position sensor 304 monitors the position of the detection portion 3003.

[0023] Furthermore, two protection mechanisms 3 are provided, which are respectively located at the front and back inner walls of the car washing machine frame 2 to protect both sides of the car body.

[0024] Working principle: The vehicle to be cleaned is parked between the running tracks 1, and the car washing machine frame 2 runs on the running tracks 1 while washing the vehicle. When the car washing machine malfunctions or the vehicle body is in a relatively biased position, the vehicle body contacts the protective sleeve 303. The protective sleeve 303 made of a flexible material can protect the vehicle body. When the force exerted by the vehicle body against the protective sleeve 303 is large, the fixed rod 302 drives the second folding part 3002 to rotate relative to the first folding part 3001. The detection part 3003 rotates along with the second folding part 3002. When the position sensor 304 detects a change in the position of the detection part 3003, the car washing machine stops and the alarm system on the car washing machine is triggered, sounding an alarm.
