Description

Technical Field

[0001] This utility model belongs to the field of massage equipment technology, and specifically refers to a massage cushion. Background Technology

[0002] Massage equipment is a series of tools and mechanical devices used to provide massage services. These devices can simulate various techniques of manual massage, such as kneading, tapping, and vibration, to help relieve muscle tension, improve blood circulation, and reduce stress and pain. Common massage equipment includes massage chairs, massage cushions, massage sticks, and foot baths. Among them, massage cushions are mainly used to massage the waist and back. Through the sliding cooperation between its massage mechanism and the massage base, the massage mechanism can move back and forth within a certain range, allowing the mechanism to massage the waist and back area simultaneously.

[0003] In existing technologies, a rack is typically incorporated into the massage base. This rack meshes with a moving gear within the massage mechanism, which is driven by a motor. This allows the massage mechanism to reciprocate along the direction of the rack. Because the massage base is thick and lacks any elasticity, it provides a poor user experience as a backrest and is easily limited by the application scenario. For example, existing chair backs are usually curved, while the bottom surface of the massage base is generally flat, making it impossible to conform to the chair back. When the user's back is pressed against the massage cushion, it causes wobbling, resulting in a poor user experience. Utility Model Content

[0004] The main purpose of this utility model is to provide a massage cushion that solves the problems existing in the prior art. It can deform within a certain range so that the massage cushion can fit better with the back of a chair, especially with a curved backrest.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A massage cushion includes a backrest, a massage mechanism, and a power source. The backrest has a hollow center and a guide plate extending vertically, as well as racks symmetrically arranged on both sides of the guide plate. The massage mechanism slides on the front of the guide plate, with its two ends respectively fitted onto the racks on both sides of the guide plate. A moving gear located at the end of the massage mechanism meshes with the corresponding rack. The power source is installed on the back of the backrest and is electrically connected to the massage mechanism.

[0007] The backrest panel is made of injection-molded material.

[0008] All corners of the backrest panel are chamfered.

[0009] The massage cushion also includes a strip circuit board extending along the length of the guide plate. The strip circuit board is installed in a groove formed on the back of the guide plate. A plurality of LED beads are provided on the strip circuit board, and a through hole is provided in the groove that is opposite to the LED beads and communicates with the front of the guide plate.

[0010] Both ends of the massage mechanism are detachably connected to a limiting plate. The limiting plate and the end of the massage mechanism are respectively clamped on the upper and lower sides of the rack, forming a through hole between them for the rack to move.

[0011] Preferably, both ends of the limiting plate are respectively secured to the back end of the massage mechanism by a screw.

[0012] The guide plate has guide flanges on both sides of its front side to guide the movement direction of the massage mechanism.

[0013] The back of the backrest panel has a mounting slot for installing the power supply.

[0014] Preferably, the mounting groove is provided with spring arms on both sides for securing the power supply; the opening of the mounting groove is covered with a power supply cover.

[0015] The power source is a lithium battery.

[0016] After adopting the above technical solution, the present invention has the following technical effects:

[0017] This invention replaces the existing massage base with a lighter and thinner backrest. Due to the reduced thickness, even when using existing plastic materials for processing and production, it can still deform to a certain extent under external pressure, thus better conforming to applications such as chair backs. The massage mechanism is no longer secured in the groove of the massage base using a limiting structure, but is instead fitted onto the racks on both sides of the guide plate. This allows it to adapt to the deformation of the racks without the moving gears disengaging from the racks and losing power during the movement of the massage mechanism, ensuring the working stability of the massage mechanism.

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] refer to Figure 1-3 As shown, this utility model discloses a massage cushion, including a backrest 1, a massage mechanism 2, and a power supply 3;

[0025] The backrest panel 1 has a hollowed-out center and is provided with a guide plate 11 extending in the vertical direction, and toothed racks 12 symmetrically arranged on both sides of the guide plate 11.

[0026] The massage mechanism 2 is slidably fitted on the front of the guide plate 11 (i.e. the front of the backrest plate 1), and its two ends are respectively fitted onto the racks 12 on both sides of the guide plate 11. The moving gear set in the end of the massage mechanism 2 meshes with the corresponding rack 12.

[0027] The power supply 3 is installed on the back of the backrest panel 1 and is electrically connected to the massage mechanism 2.

[0028] Through the above solution, this utility model replaces the existing massage base with a lighter and thinner backrest plate 1. Due to the reduced thickness, even if the existing plastic material is used for processing and production, it can still achieve a certain degree of deformation under external pressure, thus better conforming to application scenarios such as chair backs. The massage mechanism 2 is no longer locked in the groove of the massage base by a limiting structure, but is instead sleeved on the racks 12 on both sides of the guide plate 11. It can adapt to the deformation of the racks 12 and will not lose power by disengaging the moving gears from the racks 12 during the movement of the massage mechanism 1, thus ensuring the working stability of the massage mechanism 1.

[0029] The following are specific embodiments of the present invention.

[0030] The aforementioned backrest panel 1 is made of injection-molded material to ensure its elasticity under pressure deformation.

[0031] The corners of the backrest panel 1 are all chamfered to obtain ergonomic rounded corners and edges, providing users with a more comfortable tactile experience.

[0032] The present invention also includes a strip circuit board 4 extending along the length of the guide plate 11. The strip circuit board 4 is installed in a groove 13 recessed on the back of the guide plate 11. A plurality of LED beads 41 are provided on the strip circuit board 4 for decorative purposes. A through hole 131 is provided in the groove 13, which is opposite to the LED beads 41 and communicates with the front of the guide plate 11.

[0033] Both ends of the massage mechanism 2 can be detachably connected to the back of the limiting plate 5. The limiting plate 5 and the end of the massage mechanism 2 are respectively clamped on the upper and lower sides of the rack 12, and a through hole a is formed between them for the rack 12 to move.

[0034] Furthermore, both ends of the aforementioned limiting plate 5 are respectively secured to the back end of the massage mechanism 2 by a screw.

[0035] The guide plate 1 has guide flanges 14 on both sides of its front side to guide the movement of the massage mechanism 2 and reduce shaking.

[0036] The back of the aforementioned back panel 1 is provided with a mounting slot 15 for installing the power supply 3.

[0037] Furthermore, spring arms 16 for securing the power supply 3 are provided on both sides of the mounting groove 15.

[0038] Meanwhile, a power supply cover 6 is provided at the opening of the aforementioned mounting slot 15.

[0039] The aforementioned power source 3 can be a lithium battery.

[0040] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
