[0055] A brush rod mounting base 3 is hinged inside the mounting slot 102;
[0056] Each mounting slot 101 is hinged to a connecting plate 201 via an elastic rotating member. Each connecting plate 201 is integrally connected to a movable plate 2 at the end away from the mounting slot 102. The two movable plates 2 are together fitted with a brushing sleeve 7 for washing the car. The angle between the two movable plates 2 can be adaptively adjusted under the action of the elastic rotating member, so that the brushing surface of the brushing sleeve 7 can better fit the surface of the car body of different shapes.
[0057] The car wash brush using the above technical solution has an angle between the two movable plates 2 that can be adaptively adjusted under the action of the elastic rotating part. During car washing, the washing surface of the brush sleeve 7 can better fit the surface of the car body of different shapes, so that hard-to-clean dead corners can also be cleaned easily, which can greatly improve the car washing effect and efficiency.
[0058] Specifically, in this embodiment, each set of elastic rotating components includes a mounting shaft 4 and a torsion spring 5. The mounting shaft 4 is fixedly installed in the fitting groove 101 and is movably installed through the connecting plate 201. The torsion spring 5 is fitted on the mounting shaft 4, and the two torsion arms of the torsion spring 5 respectively abut against the fitting groove 101 and the interior of the connecting plate 201. The torsion spring 5 enables the angle between the two movable plates 2 to be adaptively adjusted, with an adjustment range of 90-230°.
[0059] Specifically, in this embodiment, in order to improve the installation stability of the torsion spring 5, a first abutment block 104 is integrally provided inside the mounting groove 101, and a second abutment 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 abutment block 104 and the second abutment block 202.
[0060] Specifically, in this embodiment, the mounting shaft 4 includes a T-shaped fixing rod 401 and a T-shaped fixing rod 402. The T-shaped fixing rod 401 and the T-shaped fixing rod 402 are fixedly connected by a screw to form an I-shaped mounting shaft 4. The edges of the mounting shaft 4, which consists of the T-shaped fixing rod 401 and the T-shaped fixing rod 402, are assembled and installed by screws, which can improve the efficiency of assembling the car wash brush.
[0061] Specifically, in this embodiment, in order to prevent the T-shaped fixing rod 1 401 and the T-shaped fixing rod 2 402 from rotating relative to each other and affecting the stability of use, a regular polygonal protrusion 404 is integrally provided at the end where the T-shaped fixing rod 1 401 and the T-shaped fixing rod 2 402 are connected. At the same time, a regular polygonal groove 403 is reserved at the end where the T-shaped fixing rod 2 402 is connected to the T-shaped fixing rod 1 401. The regular polygonal protrusion 404 is inserted into the regular polygonal groove 403. With the cooperation of the regular polygonal protrusion 404 and the regular polygonal groove 403, the T-shaped fixing rod 1 401 and the T-shaped fixing rod 2 402 can be prevented from rotating relative to each other, thereby avoiding affecting the stability of use of the mounting shaft 4.
[0062] Specifically, in this embodiment, the specific installation scheme of T-shaped fixing rod 1 401 and T-shaped fixing rod 2 402 is as follows: a mounting hole is reserved in T-shaped fixing rod 2 402, and a screw hole is reserved in T-shaped fixing rod 1 401. The screw of screw 1 is passed through the mounting hole, the regular polygonal groove 403 and the regular polygonal protrusion 404 in sequence and screwed into the screw hole.
[0063] Specifically, in this embodiment, in order to avoid the paint surface being damaged by accidental scratches at both ends of the connector 1, both ends of the connector 1 are set as arc-shaped structures. In order to facilitate the assembly of the mounting shaft 4, through holes 103 are reserved at both ends of the connector 1, and the mounting shaft 4 is set to pass through the through holes 103.
[0064] Specifically, in this embodiment, the specific hinge scheme between the brush rod mounting base 3 and the connecting base 1 is as follows: two symmetrically arranged rotating shafts 6 are fixedly installed at the front end of the brush rod mounting base 3 by two screws. The end of the rotating shaft 6 away from the brush rod mounting base 3 is movably extended into the interior of the mounting groove 101, so that the brush rod mounting base 3 can rotate relative to the connecting base 1 to meet the usage 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 base 3, an arc-shaped groove is provided at the end of the rotating shaft 6 away from the brush rod mounting base 3, and an arc-shaped plate 203 is integrally provided in the center at the end of the connecting plate 201 away from the movable plate 2. The outer arc surface of the arc plate 203 abuts against the arc-shaped groove. When the brush rod mounting base 3 is rotated, the rotating shaft 6 is rotated. The rotation of the rotating shaft 6 causes 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 constrained by external force. When the two movable plates 2 are pressed and attached to the surface of the car body for washing, the possibility of the two movable plates 2 swaying along the brush rod mounting base 3 (i.e., back and forth) can be reduced, thereby ensuring smooth car washing.
[0066] Specifically, in this embodiment, 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 base 3. 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 base 3. At the same time, a positioning button is installed on the brush rod 8 and is set through the positioning hole 301. The 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 popped up. After the positioning button pops up, it can be inserted into the positioning hole 301, thereby making the brush rod 8 easy to disassemble and assemble.
[0067] The connecting seat 1, brush rod mounting seat 3, connecting plate 201, and movable plate 2 of this car wash brush are all made of plastic. Since car washing involves getting wet, iron materials will rust, so the torsion spring 5 is made of stainless steel.
[0068] For brush cleaning sleeve 7, any ordinary elastic brush sleeve available on the market will suffice.
[0069] In summary, the car wash brush provided in this embodiment:
[0070] In use, install the front end of the brush rod 8 onto the rear end of the brush rod mounting base 3, then spray the surface of the car body to be cleaned with water and apply car wash liquid or car wash foam. Then, hold the brush rod 8 and press the washing surface of the brush sleeve 7 onto the car body surface and move it to clean the car body surface. Since the angle between the two movable plates 2 can be adaptively adjusted under the action of the elastic rotating part, the washing surface of the brush sleeve 7 can fit well with different shaped car body surfaces during car washing, making it easy to clean hard-to-clean dead corner areas, which can greatly improve the car washing effect and efficiency.
[0071] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
