Massage chair wireless hand controller charging compartment structure

Abstract

This utility model discloses a charging case structure for a wireless hand controller of a massage chair, relating to the field of massage chairs, aiming to solve the problem of easy damage to the hand controller and charging probe due to friction in traditional charging cases. The structure includes a cylindrical case with a lifting mechanism connected to the bottom plate, which drives the hand controller to rise and fall; it also includes a charging structure with a charging probe, a rocker arm, and a pressure rod. The probe is located at one end of the rocker arm, which is hinged to the base and connected to a return spring. The side wall of the case has charging holes for the probe to enter and exit. The contact part of the bottom plate presses or disengages from the pressure rod as the bottom plate rises and falls. When the hand controller is inserted, pressing it lowers it, the contact part presses the pressure rod, and the rocker arm rotates to allow the probe to enter for charging; when removing it, pressing activates the lifting mechanism, the contact part rises, and the return spring retracts the probe to avoid friction. The design also mentions optimized features such as a spring for the charging probe, a scissor linkage (including a specific lifting switch assembly) or a gear rack for the lifting mechanism, and hinged and locking mechanisms on the bottom plate.

Description

Technical Field

[0001] This solution relates to the field of massage chairs, and specifically to a charging bin structure for a wireless hand controller of a massage chair. Background Art

[0002] The pace of life in modern society is extremely fast. People generally face huge pressures both at work and in life. The accumulation of long-term high-intensity work and daily chores makes people physically and mentally exhausted. In this case, as a convenient relaxation tool, a massage chair can effectively help people relieve and soothe these pressures.

[0003] Since different people have different feelings, when using a massage chair, the user needs to adjust based on their own feelings. To facilitate the user's adjustment in the massage posture, the adjustment operation is generally carried out using a hand controller, that is, a device similar to a remote control. There are two types of hand controllers: wired and wireless. The wireless mode is obviously more convenient than the wired mode.

[0004] However, the wireless mode will inevitably involve the charging problem of the hand controller itself. The hand controller is usually placed in the charging bin for charging and is popped out when needed for the user to pick up. The traditional charging probe is an elastic metal probe. When the hand controller is placed in the charging bin, an external squeezing force is used to force the elastic metal probe to compress the spring and retract. After being placed in place, the metal probe pops out to achieve the electrical connection between the metal probe and the charging end of the hand controller. However, every time the hand controller is placed in the charging bin, the charging end will rub against the elastic metal probe. In the long run, this will cause damage to both the metal probe and the hand controller itself. Summary of the Invention The technical problem to be solved by this utility model is to provide a charging bin structure for a wireless hand controller of a massage chair.

[0005] The specific technical solution for this utility model to solve the above technical problem is as follows: A charging bin structure for a wireless hand controller of a massage chair, including the cylindrical bin body itself. The lower end surface of the bin body itself is provided with a bottom plate, and the bottom plate is arranged on a lifting structure. The lifting structure is used to drive at least a part of the bottom plate to rise or fall, thereby lifting the hand controller placed in the bin body to rise or fall; It also includes a charging structure, which comprises a charging probe, a rocker arm, and a pressure rod. The probe is fixedly mounted on the first end of the rocker arm, which is hinged to a base fixedly connected to the chamber body itself. A pressure rod is fixedly connected to the second end of the rocker arm. A charging hole is provided on the side wall of the chamber body for the charging probe to enter or withdraw from the chamber body. A rocker arm limiting mechanism is provided on the base, and a return spring is connected to the rocker arm. The return spring is used to drive the rocker arm to rotate around the hinge axis so that the charging probe moves away from the chamber body. An actuating part is provided on the base plate. The actuating part disengages from the pressure rod as the base plate is raised and presses the pressure rod as the base plate is lowered.

[0006] When the controller is placed into the charging case, pressing the controller forces the lifting mechanism to sink into the case itself. The descent of the base plate drives the trigger to descend as well. The descending trigger then presses the lever, forcing the lever to move downwards, which in turn causes the rocker arm to rotate around the hinge axis. The charging terminal located at the other end of the rocker arm also rotates around the axis, passes through the charging hole on the case itself, and enters the case itself. Since the controller is now inside the case, the charging probe inserted into the charging hole can contact the charging terminal on the controller, thus charging the controller.

[0007] When the hand controller is needed, press it to activate the lifting mechanism, causing it to rise. This raises the trigger, and the lever is no longer pressed by the trigger. Under the action of the return spring, the rocker arm rotates in the opposite direction, driving the charging probe to detach from the housing. The rocker arm limiting mechanism prevents excessive rotation; rotation stops once the charging probe is completely detached from the housing. Because the charging probe is completely detached, the hand controller will not rub against the charging probe when removed from the housing, thus avoiding friction between them.

[0008] Furthermore, the charging probe is spring-loaded onto the rocker arm to ensure good contact with the charging terminal of the hand controller.

[0009] Furthermore, the lifting structure is a scissor linkage mechanism; Furthermore, the lifting structure includes a lifting switch assembly, which comprises an upper assembly, a lower assembly, a compression spring, a limiting rod, and a torsion spring. The upper assembly is fixedly connected to the base plate, and the upper assembly is connected to the lower assembly via the compression spring. The compression spring drives the upper assembly and the lower assembly to move away from each other. The upper assembly has an annular limiting groove on its side, and the annular limiting groove contains four inclined surfaces connected end to end. The four inclined surfaces are uniformly inclined upward in a clockwise or counterclockwise direction, and the starting height of the adjacent subsequent inclined surface is lower than the ending height of the preceding inclined surface. The height is specified. The annular limiting groove includes an upper V-shaped portion and a lower V-shaped portion, forming an upper stop point and a lower stop point, respectively. The lower component is fixed with a limiting rod by a coil spring. The free end of the limiting rod is located in the annular limiting groove and abuts against the slope surface. The coil spring is used to drive the end of the limiting rod to always keep in contact with the slope surface. The sidewalls of the annular limiting groove and the corresponding positions of the upper V-shaped portion and the lower V-shaped portion are set at an inclined angle to the horizontal plane, which is used to push the end of the limiting rod to shift to the left or right during the up and down movement.

[0010] When the base plate is at its highest point (i.e., in the pick-up position), the end of the limiting rod is located at the lower stop of the annular limiting groove, i.e., at the lower V-shaped part. The position of the upper component is determined by the limiting fit between the end of the limiting rod and the annular limiting groove. When the hand controller is pressed, the hand controller pushes the base plate to move synchronously. The base plate pushes the upper component to move towards the lower component against the elastic force of the compression spring. The side wall of the lower V-shaped part of the annular limiting groove is inclined, so during the descent, it touches the end of the limiting rod, driving the limiting rod to swing left or right (specifically, left or right depends on whether the lowest end of the side wall of the lower V-shaped part is on the left or right side of the axis of the limiting rod end). During the continuous pressing and descent, the end of the limiting rod will move upward along the slope within the annular limiting groove until it crosses the end of the current slope and enters the starting point of the next slope. Since the end of the previous slope is higher than the starting point of the next slope, and the junction of the two is a cliff-like connection, the limiting rod... The end of the limit rod is equivalent to the starting point for "jumping" into the next slope. Because the end of the limit rod is always in contact with the slope in the annular limit groove under the action of the coil spring, the end of the limit rod cannot "jump" back up to the tail of the previous slope. When pressing again, because the end of the limit rod is restricted by the uppermost end of the annular limit groove, the hand controller can no longer be pressed down. At this time, release the hand controller, and the base plate and upper component lose the external downward pressure. Under the action of the compression spring, they begin to move upward in the opposite direction. The limit rod is still restricted by the constraint of the annular limit groove and continues to move along the new slope until it touches the upper V-shaped part of the annular limit groove, reaches the upper stop point, and enters a stable force state. The base plate is fixed at the lowest point. When pressed again, it is the process of the upper component moving from the upper stop point to the lower stop point. The process is similar and will not be described again here.

[0011] Furthermore, the lifting structure is a gear and rack mechanism, which mainly plays a supporting and balancing role, so that the hand controller can be raised and lowered smoothly as a whole.

[0012] Furthermore, the first end of the base plate is hinged to the base, and the second end is fixed to the base via a press-lock switch. By pressing, the second end pops up, and one end of the hand controller tilts out of the compartment for easy retrieval.

[0013] Furthermore, the second end of the base plate is provided with a limiting point to prevent the base plate from tilting excessively. Attached Figure Description

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] Example 1: like Figure 1As shown, a charging case structure for a wireless hand controller 4 of a massage chair includes a cylindrical case body 1. The lower end face of the case body 1 is fitted with a base plate 2. The base plate 2 is located on a lifting structure 3. The lifting structure 3 can drive at least a portion of the base plate 2 to rise or fall, thereby lifting the hand controller 4 placed inside the case body to rise or fall. A charging structure 5 is also provided, which consists of a charging probe 6, a rocker arm 7, and a pressure rod 8. The probe is fixed to the first end of the rocker arm 7, which is hinged to a base 9 that is fixedly connected to the compartment body 1. The second end of the rocker arm 7 is fixedly connected to the pressure rod 8. The side wall of the compartment body 1 is provided with a charging hole 10, which is used to allow the charging probe 6 to enter or leave the compartment body 1. The base 9 is provided with a rocker arm 7 limiting mechanism, and the rocker arm 7 is connected to a return spring 11. The return spring 11 can drive the rocker arm 7 to rotate around the hinge axis so that the charging probe 6 moves away from the compartment body 1. The base plate 2 is provided with a trigger part 12. The trigger part 12 is lifted by the base plate 2 and disengages from the pressure rod 8. It is lowered by the base plate 2 and presses the pressure rod 8. Specifically, in this example, the pressure rod 8 is formed by the extension of a three-section hinged chain link. The charging probe 6 is set on the rocker arm 7 by a spring to ensure good contact with the charging end of the hand controller 4. The lifting structure is a scissor lift mechanism; the lifting structure includes a lifting switch assembly, which includes an upper assembly 13, a lower assembly 14, a compression spring 15, a limiting rod 21, and a torsion spring. The upper assembly 13 is fixedly connected to the base plate 2, and the upper assembly 13 is connected to the lower assembly 14 via the compression spring 15. The compression spring 15 causes the upper assembly 13 and the lower assembly 14 to move away from each other. The upper assembly 13 has an annular limiting groove 16 on its side. Inside the annular limiting groove 16 are four inclined ramps 17 that are connected end to end and uniformly inclined upward in a clockwise or counterclockwise direction. The starting height of the adjacent subsequent ramp 17 is lower than that of the previous one. The inclined surface 17 has an end height. The annular limiting groove 16 contains an upper V-shaped part 18 and a lower V-shaped part 19, which form the upper stop point and the lower stop point, respectively. The lower component 14 is fixed with a limiting rod 21 by a coil spring 20. The free end of the limiting rod 21 is located in the annular limiting groove 16 and abuts against the inclined surface 17. The coil spring 20 keeps the end of the limiting rod 21 in contact with the inclined surface 17. The sidewalls of the annular limiting groove 16 and the upper V-shaped part 18 and the lower V-shaped part 19 are set at an inclined angle to the horizontal plane, which is used to push the end of the limiting rod 21 to the left or right during the up and down movement.

[0018] When the base plate 2 is at its highest point (i.e., the pick-up position), the end of the limiting rod 21 is located at the lower stop of the annular limiting groove 16, which is the position of the lower V-shaped part 19. The position of the upper component 13 is determined by the limiting fit between the end of the limiting rod 21 and the annular limiting groove 16. When the hand controller 4 is pressed, the hand controller 4 drives the base plate 2 to move synchronously. The base plate 2 pushes the upper component 13 to move towards the lower component 14 against the elastic force of the compression spring 15. Since the side wall of the lower V-shaped part 19 of the annular limiting groove 16 is inclined, it will touch the end of the limiting rod 21 during the descent, driving the limiting rod 21 to swing to the left or right (the specific direction depends on whether the lowest end of the side wall of the lower V-shaped part 19 is located to the left or right of the axis of the end of the limiting rod 21). When the descent is continued, the end of the limiting rod 21 will move upward along the slope 17 in the annular limiting groove 16 until it crosses the end of the current slope 17 and enters the starting point of the next slope 17. Since the end of the previous slope 17 is higher than the starting point of the next slope 17 and the junction of the two is a cliff-like connection, the limiting rod The end of the limit rod 21 is equivalent to the starting point of "jumping into" the next slope 17. Because the end of the limit rod 21 is always in contact with the slope 17 in the annular limit groove 16 under the action of the coil spring 20, the end of the limit rod 21 cannot "jump up" to the tail of the previous slope 17. When pressing again, because the end of the limit rod 21 is restricted by the uppermost end of the annular limit groove 16, the hand controller 4 can no longer be pressed down. At this time, the hand controller 4 is released, and the base plate 2 and the upper component 13 lose the external downward pressure. Under the action of the compression spring 15, they begin to move upward in the opposite direction. The limit rod 21 is still restricted by the annular limit groove 16 and continues to move along the new slope 17 until it touches the upper V-shaped part 18 of the annular limit groove 16, reaches the upper stop point, and enters a stable force state. The base plate 2 is fixed at the lowest point. When pressed again, it is the process of the upper component 13 moving from the upper stop point to the lower stop point. The process is similar and will not be described again.

[0019] Example 2: Unlike Example 1, the lifting structure in this example is a gear 22 and rack 23 mechanism, which mainly plays a supporting and balancing role, so that the hand controller 4 can be raised and lowered smoothly as a whole.

[0020] Example 3: Unlike Embodiment 1, in this example, the first end of the base plate 2 is hinged to the base 9, and the second end is fixed to the base 9 by a press-lock 24 switch. The second end of the base plate 2 is also provided with a limiting point.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
