Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment cleaning, in particular to a convenient cleaning device for a badminton racket. Background Art

[0002] As a highly popular indoor and outdoor fitness activity, the maintenance needs of its equipment are becoming increasingly significant as the number of participants increases, especially for badminton rackets as the core equipment. After long-term use, dust accumulated in the gaps between the net cables, sweat stains remaining on the surface of the grips, and dirt attached to the grooves of the racket frame not only affect the batting performance but may also accelerate the aging of the equipment. With the development of cleaning tool technology, cleaning products designed for sports equipment have gradually appeared on the market, such as multi-angle cleaning brushes with retractable handles, combined cleaners with micro-spray devices, and adsorption tools made of microfiber materials. These products have improved cleaning efficiency through structural improvements, but there is still room for improvement in portability and functional integration.

[0003] However, most of the cleaning devices currently available in the prior art that are specifically used for sports equipment such as badminton rackets have the following problems:

[0004] 1. Sports equipment such as badminton rackets and tennis rackets are mostly made of nylon wire or other materials that pass through the mesh frame and are interwoven to form a mesh structure. When cleaning the dirt on the surface of these wires, traditional cleaning devices can easily cause the mesh wires to be misaligned or offset due to the horizontal or vertical pushing and squeezing pressure. In severe cases, the mesh wires may even be broken and damaged. At the same time, badminton rackets and other equipment are generally cleaned in a dry cleaning and dry wiping manner to prevent water stains from entering the mesh frame. This increases the resistance between the mesh wires and the cleaning device, making it more likely to damage the mesh wires.

[0005] Second, most of the current cleaning devices for badminton rackets are not convenient enough, and it is inconvenient for users to carry them. At the same time, most of these cleaning devices can only provide a cleaning effect and cannot provide protection for the badminton racket at the same time, so their actual practicality is low.

[0006] Therefore, how to provide a convenient cleaning device for badminton rackets is a problem that those skilled in the art urgently need to solve. Summary of the Invention

[0007] One purpose of the present invention is to provide a convenient cleaning device for a badminton racket. The cleaning device provided by the present invention can provide a relatively gentle cleaning effect on the badminton racket net while ensuring the cleaning effect, preventing the racket net from being deflected and damaged. At the same time, it is easy to pick up and carry, and has a high degree of portability.

[0008] According to an embodiment of the present invention, a portable badminton racket cleaning device comprises a frame body, a handle fixed on the top of the frame body, a tail frame fixed on one side of the frame body, cleaning components rotatably provided on both sides of the frame body, the cleaning components comprising a closing cover and a cleaning sponge, the cleaning sponge being movably provided inside the closing cover, the closing cover being magnetically connected to the frame body via a magnetic strip on the surface of the frame body, a clamping component being provided inside the frame body, the clamping component comprising two sets of clamping frames arranged in staggered directions, a limiting slide being fixed on the surface of the clamping frame, and the two sets of clamping frames being slidably connected to each other via the limiting slide;

[0009] A transmission mechanism is arranged above the interior of the frame body, and a clutch mechanism is also arranged near the transmission mechanism inside the frame body. The transmission mechanism is connected and separated with the twisting mechanism through the clutch mechanism. The twisting mechanism drives the two sets of clamping frames to move in opposite directions through the transmission mechanism to clamp the racket body. The transmission mechanism can drive the clamping assembly as a whole to move back and forth up and down inside the frame body through the clutch mechanism.

[0010] Furthermore, the transmission mechanism includes an electric motor, a spline shaft and a docking shaft. The spline shaft and the docking shaft have overlapping axes and are rotatably arranged above the interior of the frame body.

[0013] Furthermore, a reciprocating assembly is provided at one end of the docking shaft away from the damping ring, and the reciprocating assembly includes two groups of turntables, a protruding pin and a vortex rod. The annular array of the protruding pin is fixed on the side surface of the turntable, and the two groups of turntables are fixed by a connecting shaft. The connecting shaft in the middle of the two groups of turntables is rotatably mounted on the inner side of the frame body through a frame plate, and the vortex rod is fixed to the end of the docking shaft, and the vortex rod is respectively engaged with the upper part of the two groups of protruding pins.

[0014] Furthermore, the turntable is fixed at the position of the maximum circular diameter away from the surface of the convex pin, and the transmission mechanism also includes two groups of connecting seats, an oblique concave rod and two groups of straight rods. The two groups of straight rods are respectively arranged on the left and right sides of the oblique concave rod, and the two groups of connecting seats are respectively arranged on the upper and lower sides of the oblique concave rod. The upper and lower sides of the oblique concave rod and the straight rod are movably connected to the connecting seats through the axial holes. The driving pin is movably connected to the connecting seat above the oblique concave rod through the driving plate, and the bottom of the connecting seat below the oblique concave rod is elastically connected to the inner frame of the frame body through two groups of tension springs.

[0015] Furthermore, tooth grooves are provided on the surface of the limiting slide, the two sets of clamping frames correspond to the two sets of tooth grooves, three sets of meshing gear groups are engaged between the two sets of tooth grooves, and the three sets of meshing gear groups are rotatably arranged at the middle position of the straight rod through the shaft sleeve.

[0016] Furthermore, both sides of the gear group are rotatably arranged in the stable frame through pin convex rotation, the stable frame is sleeved on the outside of the two groups of limit slides, and both sides of the stable frame are elastically connected to the two groups of clamping frames through pull-back springs.

[0017] Furthermore, the twisting mechanism includes a linkage shaft, a twisting roller and a twisting rope. The twisting roller is fixed on one side of the linkage shaft, and the twisting rope is wrapped around the surface of the twisting roller. The end of the twisting rope away from the twisting roller passes through two sets of guide wheels and is wrapped and fixed with the meshing group on the surface of the inclined concave rod. The docking teeth are fixed on the end of the linkage shaft away from the twisting roller, and the linkage shaft is limited to rotate inside the frame body.

[0018] Furthermore, the cleaning component includes a cleaning sponge fixed on the surface of the mounting plate close to the racket body, a ball groove fixedly set in the center of the mounting plate away from the cleaning sponge, a swing ball movably set in the ball groove, the swing ball is connected to the threaded sleeve for limited rotation through a rotating rod, the threaded sleeve is threadedly set on the surface of the closing cover, and a torsion spring is also set between the closing cover and the ball groove.

[0019] The beneficial effects of the present invention are:

[0020] The present invention provides a clamping assembly, and two sets of clamping frames arranged in staggered directions can achieve precise opposite sliding through the limiting slide, which can firmly clamp the racket body. The return spring continuously provides elastic clamping force, and cooperates with the limiting effect of the stabilizing frame to ensure that the racket is firmly positioned during movement, effectively preventing deformation of the racket frame or damage caused by uneven force on the net line. At the same time, the tooth grooves on the limiting slide engage with the gear group. When the transmission mechanism drives the oblique concave rod and the straight rod to swing, the gear group converts the swing into a reciprocating up and down linear motion of the clamping frame in the frame body. Compared with the prior art in which the cleaning tool directly pushes and pulls on the net line, the present device moves the racket as a whole so that the net surface and the fixed cleaning sponge are relatively rubbed. This way of moving the racket and keeping the cleaning component stationary makes the net line only bear the evenly distributed normal contact force, which significantly reduces the risk of net line deviation or breakage, and achieves efficient and safe cleaning.

[0021] The present invention realizes intelligent distribution of power paths by setting up a transmission mechanism and a clutch mechanism, and by pushing the Z-shaped slide to drive the transmission sleeve to move axially: when the transmission sleeve causes the clutch teeth to mesh with the docking teeth, the power of the motor is transmitted through the linkage shaft, the twisted roller, and the twisted rope, pulling the meshing group to separate the clamping frame, facilitating the rapid removal and placement of the racket body. When the transmission sleeve continues to move forward and presses against the damping ring, the power of the motor is transferred to the docking shaft, which drives the reciprocating assembly at its front end, converting the rotational motion into the reciprocating swing of the connecting seat, thereby driving the inclined concave rod and the straight rod to swing. The inclined concave rod and the straight rod are pressed against the limit slide through the meshing group, driving the clamping assembly as a whole to move stably back and forth up and down within the frame body, making the device control more integrated and meeting the effect of use in multiple modes compared to traditional cleaning equipment.

[0022] The present invention provides a cleaning component, and the closing cover is magnetically opened and closed with the frame body through a magnetic strip. In the closed state, the closing cover covers the openings on both sides of the frame body, providing physical protection for the racket body fixed inside, facilitating safe carrying, and effectively avoiding external collision or pollution. When the racket body moves up and down driven by the clamping component, the cleaning sponge is not rigidly fixed, but can passively produce multi-directional micro-sway with the ups and downs of the net line. Compared with the rigid unidirectional friction between the cleaning tool and the net line in the prior art, this design makes the contact force of the cleaning sponge on the net line more evenly dispersed, forming a cleaning action similar to "rubbing", which significantly reduces the risk of damage to the net line structure during the cleaning process. The user can adjust the position of the pendulum ball in the ball groove by rotating the threaded sleeve, thereby changing the compression amount of the torsion spring, and realizing fine control of the pressure of the cleaning sponge on the net surface of the racket body, and flexibly adapting to different cleaning needs.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0037] refer to Figures 1-9, including a frame body 1, a handle 8 is fixed on the top of the frame body 1, a tail frame 4 is fixed on one side of the frame body 1, and a cleaning assembly 2 is rotatably arranged on both sides of the frame body 1, the cleaning assembly 2 includes a closing cover 21 and a cleaning sponge 24, and the cleaning sponge 24 is movably arranged on the inner side of the closing cover 21, and the closing cover 21 is magnetically connected to the frame body 1 through a magnetic strip 22 on the surface of the frame body 1. A clamping assembly 3 is arranged inside the frame body 1, and the clamping assembly 3 includes two groups of clamping frames 31 arranged in staggered directions. The surface of the clamping frame 31 is fixed with a limiting slide 32, and the two groups of clamping frames 31 are slidingly connected to each other by the limiting slide 32; a transmission mechanism 7 is arranged above the interior of the frame body 1, and a clutch mechanism 9 is also provided at a position near the transmission mechanism 7 inside the frame body 1. The transmission mechanism 7 is connected and docked with the twisting mechanism 6 through the clutch mechanism 9. The twisting mechanism 6 drives the two groups of clamping frames 31 to move toward each other through the transmission mechanism 7 to clamp the racket body 5. The transmission mechanism 7 can drive the clamping assembly 3 as a whole to move back and forth up and down inside the frame body 1 through the clutch mechanism 9.

[0038] In this embodiment, the handle 8 on the top of the frame body 1 is convenient for the user to carry the frame body 1 directly, so as to achieve the effect of easy carrying. At the same time, a tail rack 4 is fixed to the edge position of one side of the frame body 1. The setting of the tail rack 4 can support the badminton racket shaft, and can provide strong stability of the racket shaft during carrying, so as to prevent the badminton racket shaft from breaking or bending during carrying or cleaning. In addition, the closing covers 21 on both sides of the frame body 1 can be rotated and closed. After the magnetic adsorption of the magnetic strip 22 is closed, the two sides of the frame body 1 can be clamped by the clamping assembly 3. The racket body 5 is protected so that the device as a whole has strong practicality when it can be cleaned, and the two sets of staggered clamping frames 31 on the inner side of the frame body 1 can clamp the racket body 5 net frame position in opposite directions to ensure that the racket body 5 has a strong force cleaning effect. While ensuring the clamping and release of the racket body 5, the two sets of clamping frames 31 can also be moved up and down on the inner side of the frame body 1 through the transmission mechanism 7, so that the racket body 5 moves up and down synchronously with the cleaning component to form a scrubbing effect, thereby cleaning the racket body 5 net.

[0039] refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 8The transmission mechanism 7 includes a motor 71, a spline shaft 72 and a docking shaft 73. The spline shaft 72 and the docking shaft 73 have overlapping axes and are rotatably arranged above the interior of the frame body 1. One end of the spline shaft 72 is fixedly connected to the output shaft of the motor 71. The spline shaft 72 and the docking shaft 73 are separated from each other. The clutch mechanism 9 is arranged between the spline shaft 72 and the docking shaft 73. The clutch mechanism 9 includes a Z-shaped slide 91, a movable push ring 93 and a clutch tooth 96. The movable push ring 93 is fixed to the bottom of the Z-shaped slide 91. The movable push ring 93 is rotatably sleeved on the surface of the transmission sleeve 95. The clutch tooth 96 is fixed to one end of the transmission sleeve 95. The Z-shaped slide 91 slides within the frame body 1 in a limited manner. A positioning plate 92 is rotatably arranged on the top of the Z-shaped slide 91. A socket 94 is fixed on the top surface of the frame body 1 near the positioning plate 92. The positioning plate 92 and the socket 94 are clamped together. The transmission sleeve 95 is arranged on one end of the spline shaft 72 through a spline sliding sleeve. The end of the transmission sleeve 95 away from the spline shaft 72 is aligned with the damping ring 97. The damping ring 97 is fixed to one end of the docking shaft 73. The docking teeth 98 are arranged inside the frame body 1 near the bottom of the clutch teeth 96, and the clutch teeth 96 and the docking teeth 98 are slidably engaged and docked.

[0040] The clutch gear 96 and the docking gear 98 are engaged with each other, and the clutch gear 96 is engaged with the docking gear 98, thereby making the clutch gear 96 engage with the docking gear 98. 5, and the rotation effect of the positioning plate 92 and the Z-type slide 91 enables the positioning plate 92 to rotate to engage with the socket 94, thereby positioning the Z-type slide 91 and preventing the transmission sleeve 95 from being separated during the rotation process. In addition, the Z-type slide 91 is pushed to drive the transmission sleeve 95 to continue to move forward, so that the end surface of the transmission sleeve 95 is in contact with the damping ring 97 at one end of the docking shaft 73. After contact, the positioning plate 92 and the socket 94 are locked again. In this way, under the damping effect of the damping ring 97 and the end surface of the transmission sleeve 95, the drive of the motor 71 will drive the docking shaft 73 to rotate. At the same time, the clutch teeth 96 are synchronously driven to move and separate from the docking teeth 98. At this time, the two sets of clamping frames 31 will re-clamp the racket body 5 under the elastic action of the subsequent components to ensure the stability of the racket body 5 during cleaning. The role of the clutch mechanism 9 components here is similar to the clutch control mechanism, so as to realize the use of the transmission mechanism 7 in different modes.

[0041] refer to Figure 3-Figure 7A reciprocating assembly 74 is set at the end of the docking shaft 73 away from the damping ring 97. The reciprocating assembly 74 includes two groups of turntables 741, protruding pins 742 and vortex rods 743. The annular array of protruding pins 742 is fixed to the side surface of the turntable 741. The two groups of turntables 741 are fixed by a connecting shaft. The connecting shaft in the middle of the two groups of turntables 741 is rotatably mounted on the inner side of the frame body 1 through a frame plate. The vortex rod 743 is fixed to the end of the docking shaft 73, and the vortex rod 743 is respectively engaged with the upper part of the two groups of protruding pins 742. The rotating disk 741 is fixed to the maximum diameter position of the surface of the protruding pin 742. The transmission mechanism 7 also includes two sets of connecting seats 75, an oblique concave rod 76, and two sets of straight rods 77. The two sets of straight rods 77 are respectively arranged on the left and right sides of the oblique concave rod 76. The two sets of connecting seats 75 are respectively arranged on the upper and lower sides of the oblique concave rod 76. The oblique concave rod 76 and the straight rod 77 are movably connected to the connecting seats 75 on the upper and lower sides through shaft holes. The driving pin 744 is movably connected to the connecting seat 75 above the oblique concave rod 76 through a driving plate 745. The bottom of the connecting seat 75 below the oblique concave rod 76 is elastically connected to the inner frame of the frame body 1 through two sets of tension springs 78. The surface of the limiting slide 32 has teeth 33. The two sets of clamping frames 31 correspond to the two sets of teeth 33. Three sets of gearing 34 are meshed between the two sets of teeth 33. The three gearing 34 sets are rotatably arranged at the middle section of the straight rod 77 through a shaft sleeve. The two sides of the gear group 34 are rotatably arranged in the stabilizing frame 35 through pin convex rotation. The stabilizing frame 35 is sleeved on the outside of the two groups of limiting slides 32. The two sides of the stabilizing frame 35 are elastically connected to the two groups of clamping frames 31 through return springs 36.

[0042] When the connecting rod 743 is driven to rotate, the worm rod 743 fixed at one end thereof will be driven to rotate. During the rotation of the worm rod 743, the convex pin 742 between the rotating disks 741 is engaged below the worm rod 743, so that the rotating disks 741 are driven to rotate. Here, the two sets of rotating disks 741 are fixed by a connecting shaft, and the frame body 1 passes through the two sets of rotating disks 741 to limit the two sets of rotating disks 741. When the rotating disks 741 are rotated under the force, the driving pin 744 follows the rotation to drive the driving plate 745 to swing up and down. The driving plate 745 is movably connected to the connecting seat 75 below, and the connecting seat 75 is movably connected to the single set of inclined concave rods 76 and the two sets of straight rods 77. The movement causes the oblique concave rod 76 and the two groups of straight rods 77 to swing up and down under the drive of the connecting seat 75, so that the gear group 34 is subjected to force, and the gear group 34 is engaged between the two groups of limiting slides 32. The limiting slide 32 is fixed to the clamping frame 31, so that the two groups of clamping frames 31 are subjected to force to swing up and down inside the frame body 1, driving the racket body 5 to move synchronously to achieve the scrubbing effect with the cleaning device. Here, the two groups of clamping frames 31 are mutually limited by the stabilizing frame 35, limiting the activity space of the two groups of clamping frames 31. At the same time, the frame body 1 is provided with an active slot near the clamping frame 31 to ensure that the clamping frame 31 has sufficient horizontal and vertical activity space.

[0043] refer to Figure 3 、 Figure 6 and Figure 8 The twisting mechanism 6 includes a linkage shaft 61, a twisting roller 62 and a twisting rope 63. The twisting roller 62 is fixed on one side of the linkage shaft 61. The twisting rope 63 is wrapped around the surface of the twisting roller 62. The end of the twisting rope 63 away from the twisting roller 62 passes through two sets of guide wheels and is wrapped and fixed with the meshing group 34 on the surface of the oblique concave rod 76. The docking tooth 98 is fixed on the end of the linkage shaft 61 away from the twisting roller 62, and the linkage shaft 61 is limited to rotate inside the frame body 1.

[0044] In this embodiment, the transmission sleeve 95 drives the clutch gear 96 to rotate during the rotation process. If the clutch gear 96 is in a docking meshing state with the docking gear 98, the docking gear 98 will rotate accordingly. At this time, the linkage shaft 61 is forced to drive the winding roller 62 to rotate, and the winding roller 62 tightens the winding rope 63 and pulls the gear group 34 at the middle position of the oblique concave rod 76. Here, the oblique concave design of the oblique concave rod 76 makes the surface of the gear group 34 have a larger space for winding with the winding rope 63, so that the winding rope 63 pulls the gear group 34 enables the gear group 34 to rotate, and after the gear group 34 rotates, the meshing effect between it and the tooth groove 33 causes the two groups of limiting slides 32 to drive the clamping frame 31 to move away from each other, thereby loosening the racket body 5, which is convenient for the user to directly take the racket body 5. Conversely, since the return springs 36 are set between the two sides of the stabilizing frame 35 and the clamping frame 31, under the pulling action of the return springs 36, the two groups of clamping frames 31 will re-clamp the racket body 5, thereby fixing the racket body 5.

[0045] Reference 2 and Figure 9 The cleaning component 2 includes a cleaning sponge 24 fixed on the surface of the mounting plate 23 close to the racket body 5, a ball groove 25 is fixedly provided in the center of the mounting plate 23 away from the cleaning sponge 24, and a swing ball 26 is movably provided in the ball groove 25. The swing ball 26 is connected to the threaded sleeve 27 for limited rotation through a rotating rod. The threaded sleeve 27 is threadedly provided on the surface of the closing cover 21, and a torsion spring 28 is also provided between the closing cover 21 and the ball groove 25.

[0046] The cleaning sponge 24 is fixed to the surface of the mounting plate 23, and the mounting plate 23 is movably connected with the swing ball 26 through the ball groove 25. In this way, the up and down swinging of the racket body 5 will cooperate with the combined force of its mesh surface and the cleaning sponge 24, causing the cleaning sponge 24 to swing in a coordinated manner. At the same time, the ball groove 25 will squeeze the torsion spring 28 to deform the torsion spring 28. Compared with the traditional scrubbing effect, the cleaning sponge 24 is more inclined to a kneading state for cleaning the mesh surface of the racket body 5, thereby preventing the mesh surface from being offset and damaged. At the same time, by rotating the threaded sleeve 27 to drive the swing ball 26 to move back and forth, the contact degree between the cleaning sponge 24 and the mesh surface of the racket body 5 can be better adjusted, which can more effectively adapt to the cleaning operation of the racket body 5 under different circumstances.

[0047] Working principle: First, push the Z-shaped slide 91 on the top of the frame body 1, so that the positioning plate 92 moves and rotates and engages with the socket 94 at the specified position. During this process, the Z-shaped slide 91 drives the transmission sleeve 95 to move laterally at the end of the spline shaft 72, so that one end of the transmission sleeve 95 and the damping ring 97 at the end of the docking shaft 73 are in close contact with each other. Then, pull the clamping frame 31, so that the two groups of clamping frames 31 move toward each other and expand, and the net frame position of the racket body 5 is clamped between the two groups of clamping frames 31. After releasing the clamping frame 31, the clamping frame 31 is elastically reset to the stable frame 35 under the action of the return spring 36, and the racket body 5 is clamped between the two groups of clamping frames 31. The racket body 5 is now clamped. The closing cover 21 is rotated so that the closing cover 21 is attracted to the magnetic strip 22 on the surface of the frame body 1, thereby closing the racket body 5. At this time, the cleaning sponge 24 is in contact with the mesh line of the racket body 5. Then, the motor 71 is started. The motor 71 drives the transmission sleeve 95 to rotate through the spline shaft 72. The close contact between the transmission sleeve 95 and the damping ring 97 causes the docking shaft 73 to rotate accordingly. The docking shaft 73 directly drives the worm rod 743 to rotate on the top of the two sets of turntables 741. Since the worm rod 743 bites the protruding pin 742 between the two sets of turntables 741, the turntable 741 is forced to rotate. During the rotation, the turntable 741 drives the driving plate 745 to swing up and down through the active effect of the driving pin 744 and the driving plate 745. During the swinging process, the driving plate 745 drives the connecting seat 75 to swing up and down, and the connecting seat 75 drives the gear group 34 to move up and down through the oblique concave rod 76 and the two groups of straight rods 77. The gear group 34 pulls the stabilizing frame 35 and the two groups of clamping frames 31 to move synchronously, thereby driving the displacement of the racket body 5 network line on the surface of the cleaning sponge 24. During the movement, the cleaning sponge 24 is fixed to the surface of the mounting plate 23, and the back of the mounting plate 23 is provided with a ball groove 25. The swing ball 26 is movably connected to the inner portion 25. The displacement effect causes the mounting plate 23 to be forced to deflect at a certain angle, thereby pressing the contact position between the cleaning sponge 24 and the net line at the bottom and loosening it at the top, which has a similar effect to kneading, thereby preventing the net line of the racket body 5 from being damaged or deviated. At the same time, a torsion spring 28 is provided between the ball groove 25 and the closing cover 21 to achieve an elastic reset effect to ensure a normal cleaning effect. In addition, by rotating the threaded sleeve 27, the swing ball 26 is driven to move, thereby adjusting the contact force between the cleaning sponge 24 and the net line of the racket body 5, thereby adapting to the cleaning effect in different situations.

[0048] When the racket body 5 needs to be taken, the closing cover 21 is unfolded, and the Z-shaped slide 91 is pushed and pulled, so that the transmission sleeve 95 drives the clutch gear 96 to engage with the docking gear 98, and then the motor 71 is started. The transmission effect will cause the docking gear 98 to drive the winding roller 62 to rotate through the linkage shaft 61. The winding rope 63 wrapped around the surface of the winding roller 62 will drive the gear group 34 in the middle of the straight rod 77 to rotate during the winding process. During the rotation of the gear group 34, the meshing teeth 33 on the upper and lower sides will synchronously drive the clamping frame 31 to unfold with each other through the limiting slide 32, which makes it easy to take the racket body 5, otherwise it will be clamped.
