Description
Technical Field
[0001] This utility model relates to the technical field of robotic vacuum cleaner accessories, specifically to a quick-release side brush assembly. Background Technology
[0002] With the development of smart home technology, robotic vacuum cleaners have become common household cleaning devices. The side brush, as the core cleaning component of a robotic vacuum cleaner, primarily functions to sweep dust, hair, debris, and other trash from the edges and corners of the floor to the robot's suction port, directly affecting the cleaning efficiency and cleaning range. Because the side brush needs to continuously rub against the floor during operation and is prone to getting tangled in hair, fibers, and other debris, it needs to be disassembled, cleaned, replaced, or repaired regularly to ensure the normal operation of the robotic vacuum cleaner.
[0003] Currently, most robotic vacuum cleaners on the market use screws to directly fix the side brushes to the drive motor. This means that the side brush body is locked to the output shaft of the motor with one or more screws. Although this fixing method is secure, it has many drawbacks in actual use: disassembly and installation require special tools such as screwdrivers, which is cumbersome and inconvenient; and when the side brush needs to be cleaned, the frequent screw-tightening operations greatly reduce the user experience.
[0004] Therefore, a quick-release side brush assembly is proposed to address the above problems. Utility Model Content
[0005] This utility model proposes a quick-release side brush assembly. By using a second connector in conjunction with the first connector, the side brush can be quickly installed and removed. The entire installation and removal process can be completed with simple push and pull actions, without the need for screwdrivers, wrenches or other tools. This reduces the difficulty of installing and removing the side brush, and the simplified installation and removal process shortens the time cost of replacing, cleaning or repairing the side brush.
[0006] Therefore, the technical solution adopted is as follows:
[0007] A quick-release side brush assembly includes a motor and a side brush body, wherein the output end of the motor is key-connected to a first connector, and a second connector is mounted on the top of the side brush body.
[0008] The first connector includes a sleeve, the sleeve having a positioning groove inside, and multiple spring grooves communicating with the positioning groove inside the sleeve. A clamping element is also provided in the positioning groove, and a locking block is slidably connected in the spring groove. A first spring is installed in the spring groove, and both ends of the first spring are respectively connected to the locking block and the inner wall of the spring groove. The locking block has a triangular cross-section.
[0009] The second connector includes a connecting post, which is fixed to the top of the side brush body. A fixing block is fixedly installed on the top of the connecting post, and a movable block is slidably connected to the outer side wall of the connecting post. The cross-sections of the fixing block and the movable block are both arranged in an isosceles trapezoidal shape.
[0010] Furthermore, the connecting column has a rectangular cross-section, and the movable block has a rectangular hole, through which the connecting column passes.
[0011] Furthermore, the fixed block and the movable block are the same size and shape, and the fixed block and the movable block are arranged symmetrically.
[0012] Furthermore, the cross-section of the positioning groove matches the connecting column and the movable block.
[0013] Furthermore, the clamping component includes a second spring and a clamping block, the clamping block being slidably connected to the positioning groove, and the two ends of the second spring being fixedly connected to the inner wall of the positioning groove and the top of the clamping block, respectively.
[0014] Furthermore, the inner wall of the positioning groove is provided with a vertical sliding groove, and the side wall of the clamping block is fixedly installed with a slider that cooperates with the sliding groove.
[0015] Furthermore, the number of the spring groove and the locking block disposed therein is four, and they are evenly distributed along the circumference of the sleeve.
[0016] The working principle and beneficial effects of this application are as follows:
[0017] By using the second connector in conjunction with the first connector, the side brush can be quickly installed and removed. The entire installation and removal process can be completed with simple push and pull actions, without the need for screwdrivers, wrenches or other tools. This reduces the difficulty of installing and removing the side brush, and the simplified installation and removal process shortens the time cost of replacing, cleaning or repairing the side brush.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0025] like Figures 1-4 As shown, a quick-release side brush assembly includes a motor 1 and a side brush body 2. The output end of the motor 1 is key-connected to a first connector 3, and a second connector 4 is installed on the top of the side brush body 2.
[0026] The first connector 3 includes a sleeve 31, a positioning groove 32 is provided inside the sleeve 31, and a plurality of spring grooves 33 connected to the positioning groove 32 are provided inside the sleeve 31. A clamping element is also provided in the positioning groove 32. A locking block 35 is slidably connected in the spring groove 33, and a first spring 34 is installed in the spring groove 33. The two ends of the first spring 34 are respectively connected to the locking block 35 and the inner wall of the spring groove 33. The locking block 35 has a triangular cross section.
[0027] The second connector 4 includes a connecting post 41, which is fixed to the top of the side brush body 2. A fixing block 43 is fixedly installed on the top of the connecting post 41, and a movable block 42 is slidably connected to the outer wall of the connecting post 41. Both the fixing block 43 and the movable block 42 have isosceles trapezoidal cross sections.
[0028] In this embodiment, the motor 1 is installed inside the housing of the sweeping robot, and the first connector 3 is connected to the output end of the motor 1. The first connector 3 is located at the bottom of the housing of the sweeping robot. The side brush can be quickly disassembled and assembled by connecting the second connector 4 on the top of the side brush body 2 to the first connector 3. The entire installation and disassembly process can be completed by simple pushing and pulling actions, without the need for screwdrivers, wrenches or other tools, which reduces the difficulty of disassembling and assembling the side brush. The simplified disassembly and assembly process shortens the time cost of replacing, cleaning or repairing the side brush.
[0029] Specifically, align the second connector 4 on the top of the side brush body 2 with the first connector 3 on the bottom of the sweeping robot, and push the fixing block 43 into the positioning groove 32 along its axial direction. Since the fixed block 43 has an isosceles trapezoidal cross section and the locking block 35 has a triangular cross section, the inclined surface of the fixed block 43 will contact and compress the inclined surface of the locking block 35. Under the action of the compressive force, the locking block 35 overcomes the elastic force of the first spring 34 and slides into the spring groove 33 until it is completely housed in the spring groove 33. When the fixed block 43 is fully inserted into the positioning groove 32 and the bottom height of the fixed block 43 is higher than the top of the locking block 35, the elastic force of the first spring 34 is released, pushing the locking block 35 out of the spring groove 33. At this time, one side of the locking block 35 abuts against the outer wall of the connecting post 41 for lateral limitation, and the top of the locking block 35 abuts against the bottom of the fixed block 43. For longitudinal support, the second connector 4 and the first connector 3 are fully locked together, thus completing the installation. For disassembly, push the side brush body 2 upward, which will cause the connecting post 41 of the second connector 4 to rise synchronously. The movable block 42 on the outside of the connecting post 41 will rise with the connecting post 41. Since the cross-section of the movable block 42 is an isosceles trapezoid, its inclined surface contacts and presses against the triangular inclined surface of the locking block 35. Under the action of the pressing force, the locking block 35 overcomes the elastic force of the first spring 34 and retracts into the spring groove 33 again, releasing the longitudinal support of the fixed block 43 and maintaining the upward pushing force. Then pull the side brush body 2 downward, and the connecting post 41 will cause the movable block 42 to descend. At this time, the top of the movable block 42 and the bottom of the fixed block 43 are tightly abutted, and the two do not slide relative to each other. They move synchronously, and the side brush body 2 separates from the motor 1, thus completing the disassembly.
[0030] like Figures 3-4 As shown, the connecting column 41 has a rectangular cross-section, and the movable block 42 has a rectangular hole, through which the connecting column 41 passes.
[0031] In this embodiment, since the cross-section of the connecting column 41 is rectangular, it can prevent the movable block 42 from rotating relative to it.
[0032] like Figures 3-4 As shown, the fixed block 43 and the movable block 42 have the same size and shape, and the fixed block 43 and the movable block 42 are arranged symmetrically.
[0033] like Figure 3 As shown, the cross-section of the positioning groove 32 matches that of the fixed block 43 and the movable block 42.
[0034] In this embodiment, the positioning groove 32 serves as a receiving and guiding channel, and its cross-section is perfectly matched with the fixed block 43 and the movable block 42, which can prevent the two from rotating relative to each other after assembly.
[0035] like Figure 3As shown, the clamping component includes a second spring 36 and a clamping block 37. The clamping block 37 is slidably connected to the positioning groove 32, and the two ends of the second spring 36 are fixedly connected to the inner wall of the positioning groove 32 and the top of the clamping block 37, respectively.
[0036] In this embodiment, when the second connector 4 is fully locked with the first connector 3, the fixing block 43 will press the clamping block 37 upward, causing the second spring 36 to compress. The elastic force of the second spring 36 will act in the opposite direction on the fixing block 43 through the clamping block 37, forming a pre-tightening force to prevent loosening.
[0037] like Figure 3 As shown, a vertical groove is provided on the inner wall of the positioning groove 32, and a slider that cooperates with the groove is fixedly installed on the side wall of the clamping block 37.
[0038] In this embodiment, the slider and the groove work together to restrict the movement direction of the clamping block 37, ensuring that the clamping block 37 slides only along the vertical direction of the positioning groove 32, avoiding jamming due to force deviation, and ensuring stable preload.
[0039] like Figures 3-4 As shown, there are four spring grooves 33 and four locking blocks 35 disposed therein, which are evenly distributed along the circumference of the sleeve 31.
[0040] Working principle:
[0041] Align the second connector 4 on the top of the side brush body 2 with the first connector 3 on the bottom of the sweeping robot. Push the fixing block 43 into the positioning groove 32 along its axial direction. Since the fixed block 43 has an isosceles trapezoidal cross section and the locking block 35 has a triangular cross section, the inclined surface of the fixed block 43 will contact and compress the inclined surface of the locking block 35. Under the compressive force, the locking block 35 overcomes the elastic force of the first spring 34 and slides into the spring groove 33 until it is completely housed in the spring groove 33. When the fixed block 43 is fully inserted into the positioning groove 32 and the bottom height of the fixed block 43 is higher than the top of the locking block 35, the elastic force of the first spring 34 is released, pushing the locking block 35 out of the spring groove 33. At this time, one side of the locking block 35 abuts against the outer wall of the connecting post 41 for lateral limitation, and the top of the locking block 35 abuts against the bottom of the fixed block 43. When the brush body 2 is pushed upward, the connecting post 41 of the second connector 4 rises synchronously. The movable block 42 on the outside of the connecting post 41 rises with the connecting post 41. Since the cross-section of the movable block 42 is an isosceles trapezoid, its inclined surface contacts and presses against the triangular inclined surface of the locking block 35. Under the action of the pressing force, the locking block 35 overcomes the elastic force of the first spring 34 and retracts into the spring groove 33 again, releasing the longitudinal support of the fixed block 43 and maintaining the upward pushing force. Then, the brush body 2 is pulled downward, and the connecting post 41 drives the movable block 42 to descend. At this time, the top of the movable block 42 and the bottom of the fixed block 43 are tightly abutted, and the two do not slide relative to each other. They move synchronously, and the brush body 2 separates from the motor 1, and the disassembly is completed.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
