[0053] Embodiment

[0054] The car wash brush provided by this embodiment, as Figures 1 - 21 shown, includes: a connection seat 1. A mounting groove 102 is reserved in the middle of the upper part of the connection seat 1, and fitting grooves 101 are symmetrically reserved at both ends of the connection seat 1, where:

[0055] A brush rod mounting seat 3 is hinged in the mounting groove 102;

[0056] In each fitting groove 101, a connecting plate 201 is hinged through an elastic rotating member. One end of each connecting plate 201 away from the mounting groove 102 is integrally connected with a movable plate 2. A washing sleeve 7 for washing the car is commonly sleeved outside the two movable plates 2. The angle between the two movable plates 2 can be adaptively adjusted under the action of the elastic rotating member, so that the washing surface of the washing sleeve 7 can better fit the vehicle body surfaces of different shapes.

[0057] For the car wash brush adopting the above technical solution, the angle between the two movable plates 2 provided can be adaptively adjusted under the action of the elastic rotating member. When washing the car, the washing surface of the washing sleeve 7 can better fit the vehicle body surfaces of different shapes, so that the dead corner areas that are not easy to clean can also be conveniently cleaned, and the car washing effect and efficiency can be greatly improved.

[0058] Specifically, in this embodiment, each set of elastic rotating members includes a mounting shaft 4 and a torsion spring 5. The mounting shaft 4 is fixedly installed in the fitting groove 101, and the mounting shaft 4 passes through the connecting plate 201 movably. The torsion spring 5 is sleeved on the mounting shaft 4, and the two torsion arms of the torsion spring 5 respectively abut against the inside of the fitting groove 101 and the connecting plate 201. The provided torsion spring 5 enables the angle between the two movable plates 2 to be adaptively adjusted, and the adjustment range is 90 - 230°.

[0059] Specifically, in this embodiment, in order to improve the installation stability of the torsion spring 5, a first resisting block 104 is integrally provided inside the fitting groove 101. At the same time, a second resisting block 202 is integrally provided on the inner wall of the connecting plate 201, and the two torsion arms of the torsion spring 5 are respectively abutted against the first resisting block 104 and the second resisting block 202.

[0060] Specifically, in this embodiment, the installed shaft 4 is provided with a first T-shaped fixing rod 401 and a second T-shaped fixing rod 402. The first T-shaped fixing rod 401 and the second T-shaped fixing rod 402 are fixedly connected by a first screw, and an I-shaped installed shaft 4 is formed. The edge of the installed shaft 4 composed of the first T-shaped fixing rod 401 and the second T-shaped fixing rod 402 is assembled and installed by the first screw, which can improve the efficiency of assembling the car wash brush.

[0061] Specifically, in this embodiment, in order to prevent the first T-shaped fixing rod 401 and the second T-shaped fixing rod 402 from rotating relative to each other and affecting the use stability, a regular polygon convex block 404 is integrally provided at one end where the first T-shaped fixing rod 401 and the second T-shaped fixing rod 402 are connected. At the same time, a regular polygon groove 403 is reserved at one end where the second T-shaped fixing rod 402 and the first T-shaped fixing rod 401 are connected. The regular polygon convex block 404 is inserted into the regular polygon groove 403 in a fitting manner. With the cooperation of the regular polygon convex block 404 and the regular polygon groove 403, the first T-shaped fixing rod 401 and the second T-shaped fixing rod 402 can be prevented from rotating relative to each other, thereby avoiding affecting the use stability of the installed shaft 4.

[0062] Specifically, in this embodiment, the specific installation scheme of the first T-shaped fixing rod 401 and the second T-shaped fixing rod 402 is as follows: an installation hole is reserved in the second T-shaped fixing rod 402, and a screw hole is reserved in the first T-shaped fixing rod 401. The screw rod of the first screw passes through the installation hole, the regular polygon groove 403 and the regular polygon convex block 404 in sequence and is screwed into the screw hole.

[0063] Specifically, in this embodiment, in order to prevent the two ends of the connecting seat 1 from accidentally scratching the car paint and damaging the car paint surface, both ends of the connecting seat 1 are set as arc-shaped structures. In order to facilitate the assembly of the installed shaft 4, insertion holes 103 are reserved at both ends of the connecting seat 1, and the installed shaft 4 is arranged through the insertion holes 103.

[0064] Specifically, in this embodiment, the specific hinged scheme of the brush rod mounting seat 3 and the connecting seat 1 is as follows: two symmetrically arranged rotating shafts 6 are fixedly installed at the front end of the brush rod mounting seat 3 by second screws. One end of the rotating shaft 6 away from the brush rod mounting seat 3 is movably extended into the interior of the fitting groove 101, so that the brush rod mounting seat 3 can rotate relative to the connecting seat 1 to meet the use requirements during car washing.

[0065] Specifically, in this embodiment, in order to enable the movable plate 2 to be linked with the brush rod mounting seat 3, an arc-shaped groove is provided at one end of the rotating shaft 6 away from the brush rod mounting seat 3. At the center of the end of the connecting plate 201 away from the movable plate 2, an arc-shaped plate 203 is integrally provided. The outer arc surface of the arc-shaped plate 203 is in contact with the arc-shaped groove. When the brush rod mounting seat 3 is rotated, the rotation of the brush rod mounting seat 3 drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the arc-shaped groove to apply a force to the arc-shaped plate 203. This force is transmitted to the movable plate 2 through the connecting plate 201, so that the movable plate 2 is subject to external force constraints. When the two movable plates 2 are pressed against the vehicle body surface for car washing, the possibility of the two movable plates 2 shaking along the brush rod mounting seat 3 (i.e., front and back) can be reduced, thus ensuring smooth car washing.

[0066] Specifically, in this embodiment, in order to facilitate the operation of the car wash brush, a brush rod 8 is detachably installed at the rear end of the brush rod mounting seat 3. In order to facilitate the disassembly and assembly of the brush rod 8, a positioning hole 301 is reserved on the side wall of the brush rod mounting seat 3. At the same time, a positioning button is installed on the brush rod 8, and the positioning button is arranged through the positioning hole 301. One end of the positioning button inserted into the brush rod 8 has a spring support, so that the positioning button can be pressed and automatically bounce up. After the positioning button bounces up, it can be inserted into the positioning hole 301, so that the brush rod 8 is convenient for disassembly and assembly.

[0067] Among them, the connecting seat 1, the brush rod mounting seat 3, the connecting plate 201 and the movable plate 2 of this car wash brush are all made of plastic materials. Because the car wash needs to get wet and iron materials will rust, the torsion spring 5 is made of stainless steel materials.

[0068] The brushing sleeve 7 can use a common elastic brush sleeve on the market.

[0069] In summary, the car wash brush provided by this embodiment:

[0070] When in use, install the front end of the brush rod 8 at the rear end of the brush rod mounting seat 3, then wet the surface of the vehicle body to be cleaned with water and spray car wash liquid or car wash foam. Then hold the brush rod 8 and press the brushing surface of the brushing sleeve 7 against the vehicle body surface and move it to clean the vehicle body surface. Since the angle between the two movable plates 2 can be adaptively adjusted under the action of the elastic rotating member, the brushing surface of the brushing sleeve 7 can better fit the vehicle body surface of different shapes during car washing, making it convenient to clean the dead corner areas that are not easy to clean, and can greatly improve the car wash effect and efficiency.

[0071] The above is only a preferred embodiment of the present invention, and does not limit the implementation manner and protection scope of the present invention. For those skilled in the art, it should be able to realize that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
