Description

Technical Field

[0001] The utility model relates to the technical field of car washing brushes, in particular to an improved vertical car washing brush for a car washing machine. Background Art

[0002] A car washing machine is mainly a machine that uses a computer to control brushes and high-pressure water to automatically wash a car. Usually, the body of a private car has a curvature. To ensure that the vertical car washing brush can fit more conveniently with the vehicle surface, a universal joint is used to connect the motor that drives the vertical brush to rotate and the connecting shaft of the vertical brush. In this way, after the vertical brush contacts the vehicle surface, the vertical brush can generate a corresponding inclination angle to facilitate fitting with the vehicle surface.

[0003] For example, the Chinese patent technical document with the publication number CN218750705U discloses an integrated double-brush installation structure and a car washing device for a car washing machine, including a double-brush unit, a brush connecting arm, a universal connector, a main connecting arm, and a car washing machine frame. The main connecting arm is installed on the car washing machine frame. The middle part of the brush connecting arm is fixedly hoisted with the lower part of the end of the main connecting arm through a universal connector. The lower parts of both ends of the brush connecting arm are fixedly installed with the double-brush unit. The double-brush unit is vertically arranged and is located on both sides of the car washing channel of the car washing machine frame.

[0004] In the above technical solution, the vertical brush generates an inclination angle after contacting the vehicle surface through the universal connector to facilitate fitting with the vehicle surface. However, it is found in the actual use process that during the process of washing the vehicle surface by the vertical brush, due to the different curvatures of the vehicle surface, the vertical brush is prone to jitter during the reciprocating movement, affecting the fitting with the vehicle surface. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an improved vertical car washing brush for a car washing machine, which can reduce the jitter generated during the rotation of the vertical car washing brush and facilitate fitting with the vehicle surface.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An improved vertical car washing brush for a car washing machine, including a connecting beam and a vertical brush body. A connecting shaft is provided at the end of the vertical brush body. A rotating shaft rotatably connected in the vertical direction is provided on the connecting beam. One end of the rotating shaft is connected with a driving motor, and one end is connected with a universal joint. The universal joint is connected with the connecting shaft on the side far from the rotating shaft. An installation sleeve extending downward is provided at the bottom of the connecting beam. A force application device is provided inside the installation sleeve. The force application device is used to apply a force to the connecting shaft to reduce the jitter generated when the vertical brush body rotates and facilitate the vertical brush body to fit with the vehicle surface.

[0007] The utility model is further configured as follows: the force-applying device includes a connecting sleeve, a connecting groove is provided on the inner side of the connecting sleeve, the connecting grooves are multiple and evenly distributed along the circumference, a force-applying rod is provided in the connecting groove, a spring is provided between the force-applying rod and the connecting groove, one end of the spring is fixed to the force-applying rod, and the other end is fixed to the bottom of the connecting groove.

[0008] The utility model is further configured as follows: the force applying rod is adapted to the connecting groove so that the outer wall of the force applying rod is fitted with the inner wall of the connecting sleeve.

[0009] The utility model is further configured as follows: the inner wall of the mounting sleeve is provided with a protruding connecting convex ring, the connecting sleeve is provided with a first threaded hole penetrating therethrough, the first threaded holes are multiple and evenly distributed along the circumference, the connecting convex ring is provided with a second threaded hole opposite to the first threaded hole, and the first threaded hole and the second threaded hole are connected by a locking member.

[0010] The utility model is further configured as follows: a groove is provided on the side of the force applying rod away from the connecting sleeve, a ball matched with the groove is provided in the groove so that the ball can rotate in the groove, a retaining frame is fixed to the end of the force applying rod, a clearance hole opposite to the ball is provided on the retaining frame, and the diameter of the clearance hole is smaller than the diameter of the ball so that part of the ball can pass through the clearance hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] Since the installation sleeve is provided, the installation sleeve can provide an installation position for the installation of the force-applying device. In this way, when the vertical brush bounces due to different curvatures on the vehicle surface during the process of cleaning the vehicle surface, the force-applying device can apply resistance to the connecting shaft of the vertical brush body to reduce the shaking amplitude of the car wash vertical brush during the rotation process. Therefore, the technical problem of the vertical brush body having a large jumping amplitude during the process of cleaning the vehicle surface in the prior art is effectively solved, and the vertical brush body can be easily fitted to the vehicle surface to ensure the cleaning effect of the vehicle surface. Moreover, by applying resistance to the connecting shaft of the vertical brush body, the vertical brush body can be easily fitted to the vehicle surface to further improve the cleaning effect of the vehicle surface.

[0016] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] As Figures 1 to 3 shown, the present utility model discloses an improved car wash vertical brush for a car wash machine, which includes a connecting beam 1 and a vertical brush body 2. A connecting shaft 3 is provided at the end of the vertical brush body 2. A rotating shaft 4 rotatably connected in the vertical direction is provided on the connecting beam 1. One end of the rotating shaft 4 is connected to a driving motor 10, and one end is connected to a universal joint 5. The universal joint 5 can adopt the existing structure. The universal joint 5 is located on the side away from the rotating shaft 4 and is connected to the connecting shaft 3. An installation sleeve 6 extending downward is provided at the bottom of the connecting beam 1. A force applying device is provided inside the installation sleeve 6. The force applying device is used to apply a force to the connecting shaft 3 to reduce the jitter generated when the vertical brush body 2 rotates and facilitate the fitting of the vertical brush body 2 to the vehicle surface. During the process of cleaning the vehicle surface with the vertical brush, when the vertical brush jumps due to different curvatures on the vehicle surface, the force applying device can apply a resistance to the connecting shaft 3 of the vertical brush body 2 to reduce the jitter amplitude generated during the rotation of the car wash vertical brush, thereby facilitating the fitting of the vertical brush body 2 to the vehicle surface to ensure the cleaning effect on the vehicle surface. And by applying a resistance to the connecting shaft 3 of the vertical brush body 2, it can also facilitate the close contact between the vertical brush body 2 and the vehicle surface to further improve the cleaning effect on the vehicle surface.

[0019] In this embodiment, the specific structure of the force application device includes a connecting sleeve 71. Inside the connecting sleeve 71, there are connecting grooves 711. There are multiple connecting grooves 711 and they are evenly distributed in a circumferential manner. Inside the connecting grooves 711, there are force application rods 72. Between the force application rods 72 and the connecting grooves 711, there are springs 73. One end of the spring 73 is fixed to the force application rod 72, and one end is fixed to the bottom of the connecting groove 711. When the vertical brush body 2 comes into contact with the vehicle surface and generates an inclination angle, the connecting shaft 3 of the vertical brush body 2 can gradually come into contact with the force application rod 72 and gradually extrude the force application rod 72 to compress the spring 73. The acting force generated by the compression of the spring 73 can act on the connecting shaft 3 of the vertical brush body 2 through the force application rod 72. In this way, a resistance can be applied to the connecting shaft 3 of the vertical brush body 2 to reduce the shaking amplitude generated during the rotation of the car washing vertical brush, and the resistance applied to the connecting shaft 3 can drive the vertical brush body 2 to closely fit the vehicle surface.

[0020] In this embodiment, the force application rod 72 is adapted to the connecting groove 711 so that the outer wall of the force application rod 72 fits the inner wall of the connecting sleeve 71. In this way, during the extrusion process of the force application rod 72, a guiding fit can be formed between the force application rod 72 and the connecting groove 711, thereby playing a guiding role in the movement of the force application rod 72.

[0021] In this embodiment, on the inner wall of the mounting sleeve 6, there is further a protruding connecting convex ring 61. On the connecting sleeve 71, there are through first threaded holes. There are multiple first threaded holes and they are evenly distributed in a circumferential manner. On the connecting convex ring 61, there are second threaded holes opposite to the first threaded holes. The first threaded holes and the second threaded holes are connected by a locking member 100. When connecting the connecting sleeve 71 and the mounting sleeve 6, first slide the connecting sleeve 71 from bottom to top into the mounting sleeve 6. After the connecting sleeve 71 and the mounting sleeve 6 come into contact with each other, by screwing in the locking member 100 that forms a threaded fit with the first threaded holes and the second threaded holes, the connection between the connecting sleeve 71 and the mounting sleeve 6 can be completed, thus facilitating the installation of the force application device.

[0022] In this embodiment, on the side of the force application rod 72 away from the connecting sleeve 71, there is further an embedding groove. Inside the embedding groove, there is a ball 8 adapted to the embedding groove so that the ball 8 can rotate inside the embedding groove. At the end of the force application rod 72, there is a cage 9 fixed. On the cage 9, there is a relief hole opposite to the ball 8. The diameter of the relief hole is smaller than the diameter of the ball 8 so that part of the ball 8 passes through the relief hole. Through the setting of the cage 9, it can prevent the ball 8 from falling off the embedding groove. And the setting of the ball 8 can make the ball 8 abut against the connecting shaft 3 when the connecting shaft 3 extrudes the force application rod 72. In this way, during the process of the driving motor 10 driving the vertical brush body 2 to rotate through the universal joint 5, the friction between the ball 8 and the connecting shaft 3 is rolling friction, thus facilitating the rotation of the vertical brush body 2.

[0023] This specific embodiment is only an interpretation of the present utility model, and it does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
