Description

Technical Field

[0001] This utility model belongs to the field of cleaning products technology, and in particular relates to a car brush with an adjustable brushing angle. Background Technology

[0002] The existing automotive brush head fixing structure forcibly constrains the working end posture through rigid connection, and its dual-axis degrees of freedom lack pitch / yaw adjustment and surface geometry adaptation.

[0003] Chinese patent application No. 202421158646.8 discloses a car brush with an elastic structure for controlling the brushing angle, including a handle and a brush head. The handle contains a water pipe, and the brush head includes an adjustment head and a brush head sleeve. The brush head sleeve has a mounting groove with a water spray nozzle at the bottom. The mounting groove has vertical sidewalls on the left and right, and the sidewalls are symmetrically provided with several angle grooves and pivot holes. The adjustment head has a hollow interior with a water passage cavity. The outer wall of the adjustment head has a head body pivot and spring jump blocks on both sides. The spring jump block includes a jump block and a spring. The end of the jump block has a spring hole, and the outer wall of the head end protrudes to form a hemispherical jump bead. The head body pivot is inserted into the pivot hole, and the spring jump block is inserted into the angle grooves of different angles during the rotation of the adjustment head pivot, allowing for adjustment of the tilt angle during brushing.

[0004] In the above technical solution, the fixed angle between the rod head and the handle is adjusted by making the jumping ball and the angle groove cooperate with each other. However, in the above technical solution, the jumping balls on both sides can only be manually controlled to move closer to each other to unlock the rod head and the handle. After the jumping ball is re-embedded into the angle groove, the angle between the rod head and the handle is fixed again. It can only realize the gear adjustment corresponding to the angle groove, and cannot keep the rod head and the handle in an unlocked state so that the rod head and the handle can swing relative to each other, so that the rod head can adapt to the complex surface with multiple curvatures on the vehicle body. Summary of the Invention

[0005] To address the shortcomings of existing technologies, an adjustable brush angle is provided for automobiles.

[0006] This utility model is achieved using the following technical solution:

[0007] An adjustable brush for automobiles includes a handle and a brush head disposed at one end of the handle. The brush head is connected to a sleeve fitted on the handle. The sleeve and the brush head are hinged together by a first hinge shaft. The sleeve has a limiting hole arranged in a ring array with the first hinge shaft as the center. A second hinge shaft is disposed on the sleeve near the first hinge shaft. When the second hinge shaft is inserted into the limiting hole, it can fix the angle of the brush head together with the first hinge shaft. The sleeve has a trigger component that can simultaneously move the two axial ends of the second hinge shaft closer or further apart. The sleeve has a locking component for keeping the trigger component stable without external force.

[0008] Users can select the limiting hole for the insertion of the second hinge shaft according to the required brush head angle. When the axial ends of the second hinge shaft approach each other simultaneously by triggering the component, the axial ends of the second hinge shaft separate from the limiting hole, thereby unlocking. At this time, after aligning the axial ends of the second hinge shaft with the required limiting hole, the user can move the axial ends of the second hinge shaft away from each other at the same time, so that the axial ends of the second hinge shaft can be reinserted into the limiting hole, thus fixing the angle of the brush head.

[0009] When the user needs a movable brush head, the two ends of the second hinge shaft are brought close together at the same time. At this time, the trigger component is fixed by the locking member to keep it in a stable state, so that the brush head is only hinged to the housing through the first hinge shaft, allowing the brush head to swing relative to each other.

[0010] The triggering component can be two sliders that are wedged into the second hinge shaft in the radial direction. By abutting the inclined surface, the two axial ends of the second hinge shaft are brought closer together at the same time. At this time, the locking component is a plate-like structure that can block the sliding path of the slider. Alternatively, the triggering component can be a slider that moves in a direction parallel to the axis of the second hinge shaft. By driving the two sliders to move closer together, the two axial ends of the second hinge shaft are brought closer together at the same time. At this time, the locking component is a snap-like structure that can clamp and constrain the slider.

[0011] Preferably, the locking member includes at least one abutting surface for abutting against the triggering component. When the triggering component simultaneously brings both ends of the second hinge shaft close to the first limit state, the locking member is slid to the first limit position, and the abutting surface of the locking member abuts against the triggering component to keep the triggering component in a stable state.

[0012] When the contact surface of the locking component comes into contact with the trigger component, a geometric self-locking pair is formed, which locks and fixes the trigger component, thereby keeping the trigger component in a stable state, and thus realizing the switching between mechanical limiting and free state of the brush head using the second hinge shaft.

[0013] Preferably, the housing is provided with a support base, and the support base has a locking slide for the locking member to slide. The support base has windows on both ends of the locking slide in the width direction for the triggering component to be exposed.

[0014] By integrating the control of the locking and triggering components through the support base, compared with the separate multi-actuator control system, it can save the space occupied by the housing and facilitate one-handed operation by the user; while the visual window structure formed by the support base allows the user to operate more intuitively.

[0015] Preferably, the triggering component includes a sliding block that is slidably disposed in the windows on both sides. The two end faces of the two sliding blocks perpendicular to the sliding direction are respectively provided with a protrusion and a connecting part. The connecting parts of the two sliding blocks are respectively connected to the two ends of the second hinge shaft in the axial direction.

[0016] By setting the pressing slider as a linkage structure, the movement of the protrusion and the connecting part are coordinated.

[0017] Preferably, a reset element is provided between the two pressing sliders.

[0018] The reset component keeps the two pressing sliders at their extreme positions far apart, ensuring that both ends of the second hinge shaft remain embedded and that the brush head angle is fixed.

[0019] The reset component can be a spring connected between the two pressing sliders, an elastic filler filling between the two pressing sliders, or a magnetic component with the same magnetic poles disposed between the two pressing sliders.

[0020] Preferably, when the two pressing sliders are pressed and are in the extreme position of being close to each other, the connecting part drives the two ends of the second hinge shaft to approach the first extreme state; when the two pressing sliders slide to the extreme position of being far apart from each other under the action of the reset member, the connecting part drives the two ends of the second hinge shaft to move away from the second extreme state.

[0021] Compared to the lever structure that drives the connecting part by pressing the slider, it can be controlled by operation that conforms to the user's usage logic.

[0022] Preferably, the locking member has baffles extending from both sides of the protrusion, and the baffles on both sides extend through the locking slide into the support base, thereby interlocking with the pressing slider.

[0023] Preferably, the ends of the baffles on both sides that are close to each other and the ends of the two protrusions that are far apart are both planar, and the ends of the baffles on both sides that are close to each other can respectively abut against the ends of the two protrusions that are far apart.

[0024] By abutting the flat surface of the baffle against the protrusion, compared to the abutting method of curved surface contact or point contact, the locking potential energy between the two can be maintained, so that the vibration caused by the assembly gap during the reciprocating sliding of the brush head is difficult to unlock.

[0025] Preferably, the housing is provided with a limiting slide along the axial direction of the second hinge axis, the connecting part is embedded in the limiting slide and can slide relative to it, and the housing is provided with through holes at both ends of the limiting slide along the length direction for the second hinge axis to pass through.

[0026] The sliding trajectory of the connecting part is limited by the limiting slide, so that it coordinates with the sliding trajectory of the pressing slider. This avoids the pressing slider from wobbling due to assembly gaps, which could cause the pressing slider to jam, thus ensuring the smoothness of the pressing slider's sliding.

[0027] Preferably, the brush head has a movable space for the sleeve to swing, and the movable space has at least one limiting wall located on the swing path of the sleeve.

[0028] The limiting wall constrains the end position of the brush head's swing trajectory, thereby preventing the brush head from rotating too far and causing excessive twisting of the first or second hinge shaft.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] The dual-axis collaborative control structure is formed by the first hinge shaft and the second hinge shaft. The angle of the brush head is fixed and controlled by the insertion and cooperation of the limiting hole and the second hinge shaft. The interlocking mechanism between the locking part and the pressing slider allows the pressing slider to maintain a contracted steady state in a zero power consumption state, thereby enabling the brush head to maintain free swing.

[0031] By setting a limiting wall, when the brush head is in a free swinging state or when the brush head is fixed at the maximum angle, the termination position of the brush head can be constrained and supported, thereby preventing the brush head from rotating too far and causing excessive twisting of the first hinge shaft or the second hinge shaft.

[0040] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1 As shown, this embodiment discloses an adjustable brush angle car brush, including a handle 11, as... Figure 7 As shown, the handle 11 can be extended or shortened using an existing telescopic structure. A brush head 30 is provided at the front end of the handle 11, and the brush head 30 is fitted onto the handle 11 via a sleeve 12. Figure 2 As shown, the brush head 30 includes a first assembly portion 13 for connecting to the handle 11 and a second assembly portion 14 for connecting the brush head 30. The first assembly portion 13 has a sleeve-type structure, and the second assembly portion 14 has a flat columnar structure. To ensure the structural strength between the first assembly portion 13 and the second assembly portion 14, the first assembly portion 13 and the second assembly portion 14 can be configured as an flared opening from the handle 11 to the brush head 30, such as... Figure 3 As shown, the housing 12 consists of an upper bottom shell 15 and a lower bottom shell 16 that interlock with each other. The upper bottom shell 15 and the lower bottom shell 16 are fixed and assembled by a fixing structure that is the same as that in the prior art.

[0042] The brush head 30 has an upwardly extending mounting base 31 on its back side. The mounting base 31 has an arc-shaped enclosure structure. The brush head 30 is hinged to the first hinge shaft 32 on the upper bottom shell 15 through the mounting base 31. The brush head 30 has an active space for the shell 12 to swing inside the mounting base 31. The active space has a limiting wall perpendicular to the back side of the brush head 30. The limiting wall is transversely intersecting the swing path of the shell 12 relative to the brush head 30.

[0043] The inner circular surface of the mounting base 31 is provided with limiting holes 33 arranged in an annular array with the first hinge shaft 32 as the center. The housing 12 is provided with a second hinge shaft near the first hinge shaft 32. The second hinge shaft consists of two spaced pins 25. The two ends of the second hinge shaft are the ends of the two pins 25 that are far apart from each other. When the pins 25 are inserted into the limiting holes 33, they can fix the angle of the brush head 30 with the first hinge shaft 32. The housing 12 is provided with a trigger component 20 that can make the two pins 25 move closer or further apart at the same time. The housing 12 is provided with a locking component for keeping the trigger component 20 in a stable state without external force.

[0044] like Figure 4 As shown, the upper bottom shell 15 is provided with a support base 17, and the support base 17 is provided with an upward-opening locking slide 18 for the locking member to slide. The support base 17 is provided with windows 19 on both ends of the locking slide 18 in the width direction for the triggering component 20 to be exposed.

[0045] like Figure 5 As shown, the trigger assembly 20 includes a push slider 21 that is slidably disposed in the windows 19 on both sides. The two push sliders 21 can move closer to each other or further away in a direction perpendicular to the sliding member. The two end faces of the two push sliders 21 perpendicular to the sliding direction are respectively provided with a protrusion 22 and a connecting part 23. The connecting part 23 of the two push sliders 21 is respectively connected to two pins 25. A reset member is provided between the two push sliders 21. The reset member is a thrust spring 24.

[0046] When the two pressing sliders 21 are pressed and are in the extreme position of being close to each other, they drive the two pins 25 to approach to the first extreme state, which is the position where the two pins 25 are close to each other. When the two pressing sliders 21 slide to the extreme position of being far apart under the action of the thrust spring 24, the connecting part 23 drives the two ends of the second hinge shaft to move away from each other to the second extreme state, which is the position where the two pins 25 are far apart from each other. This allows the two pins 25 to move closer or further apart, so that the second hinge shaft can move relative to each other.

[0047] like Figure 6As shown, the locking element is a sliding plate 26. Baffles 27 extend from the two sides of the sliding plate 26 toward the protrusions 22. The baffles 27 extend through the locking slide 18 into the support base 17. The distance between the two baffles 27 is equal to the width between the two ends of the protrusions 22 when the two pressing sliders 21 move the protrusions 22 to their extreme positions of close proximity. The close ends of the two baffles 27 are abutting surfaces 271 for abutting against the protrusions 22. The abutting surfaces 271 of the two baffles 27 and the ends of the two protrusions 22 that are far apart are both flat. The close ends of the two baffles 27 can abut against the ends of the two protrusions 22 that are far apart, respectively.

[0048] When the slider 21 is pressed, causing the two pins 25 to approach the first limit state simultaneously, the sliding plate 26 is slid to the first limit position. The sliding plate 26 then clamps the two end faces of the protrusions 22 of the two sliders 21 through the abutment surface 271 of the baffle 27, thereby keeping the slider 21 in a stable state and causing the pins 25 to disengage from the limiting hole 33.

[0049] The lower shell 16 has a limiting slide 28 along the axial direction of the second hinge shaft. The connecting part 23 is embedded in the limiting slide 28 and can slide relative to it. The sleeve 12 has through holes 29 at both ends of the limiting slide 28 in the length direction for the second hinge shaft to pass through.

[0050] The user can select the limiting hole 33 for inserting the pin 25 according to the required angle of the brush head 30. By squeezing the slider 21, the connecting part 23 is driven to slide synchronously, so that the two pins 25 are brought closer to each other, and then the two pins 25 are separated from the limiting holes 33 located on both sides of the mounting base 31, thereby unlocking. At this time, after aligning the two pins 25 with the required limiting hole 33, the user releases the slider 21. The push spring 24 drives the connecting part 23 through its own elasticity, so that the two pins 25 are moved away from each other at the same time, so that the two pins 25 can be reinserted into the limiting hole 33, and the angle of the brush head 30 is adjusted and fixed.

[0051] When the user needs the movable brush head 30, the two pins 25 are brought close together at the same time. At this time, the sliding plate 26 drives the baffle 27 to clamp and fix the protrusion 22 on the pressing slider 21, thereby separating the two pins 25 from the limiting hole 33 and keeping them in a stable state. This allows the brush head 30 to maintain free swing by being hinged only between the first hinge shaft 32 and the housing 12.
