Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a chair with a buttock massage function. Background Technology

[0002] As people's quality of life improves, chairs with massage functions are widely used in homes, offices, and leisure venues. Some chairs, in order to provide a massage function for the user's buttocks, typically have a massage component installed inside the seat. The massage heads in this component extend from the top surface of the seat to contact the user's buttocks, thus achieving a massage effect. To accommodate the extension of the massage components, the top surface of the seat of such chairs must have multiple holes for the massage components to pass through. However, in existing technology, chairs with buttock massage functions generally do not have corresponding dustproof components on the top surface of the seat. Since the holes in the seat are directly connected to the outside, dust, hair, and other debris from the external environment can easily fall into the seat through these holes when the chair is not in use or is stored away. Dust and other debris that fall into the seat can interfere with the normal operation of the massage components, such as causing them to jam and affecting the massage effect, or even shortening their lifespan. On the other hand, the accumulation of debris inside the seat can also increase the difficulty of cleaning the seat, making it difficult to maintain its hygiene and potentially negatively impacting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a chair with a hip massage function. This addresses the technical problem that existing chairs with hip massage functions generally do not have corresponding dustproof components on the top surface of the seat. When the chair is not in use or is stored normally, dust, hair, and other debris from the external environment can easily fall into the seat through these holes.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A chair with a buttock massage function includes a seat board with a storage cavity inside. Multiple sets of passage components distributed along the seat depth direction are arranged on the top surface of the seat board, each set of passage components communicating with the storage cavity. Multiple sets of rotatable blocking components distributed along the seat depth direction are arranged on the top wall of the storage cavity, each set of blocking components installed at the bottom of each set of passage components and capable of covering each set of passage components. Multiple sets of massage components that can move vertically synchronously along the seat depth direction are arranged inside the storage cavity. Each set of massage components is connected to each set of blocking components by a connecting component. When a massage component rises, the connecting component drives the corresponding blocking component to rotate downwards, moving it away from the corresponding passage component.

[0005] Working principle: When the massage function of the seat is activated, the massage component rises, causing the corresponding blocking component to rotate downwards via the connecting component, moving it away from the corresponding passage component. This allows the massage component to extend out of the seat and contact the user's buttocks for massage. When the massage function is not needed, the massage component descends and extends into the storage cavity. At this time, the blocking component rotates upwards to approach and conform to the corresponding passage component, thus isolating the storage cavity from the outside environment.

[0006] Beneficial effects: By installing a shielding component corresponding to the passage component on the top wall of the storage cavity, when the massage function is not needed, the massage component descends and extends into the storage cavity, and the shielding component rotates upward and approaches and fits against the corresponding passage component. This can reliably isolate the storage cavity from the outside world, preventing dust, hair and other debris from falling into the storage cavity through the passage component, thus keeping the inside of the storage cavity clean.

[0007] The linkage between the massage component and the blocking component is achieved through the connecting component between them. No additional drive device is needed to control the blocking component separately. This simplifies the overall structure while realizing the function, making it easier to manufacture and assemble.

[0010] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0011] Example: like Figures 1-4As shown, a chair with a buttock massage function includes a seat plate 1, which serves as the basic load-bearing component of the chair. The seat plate 1 has a hollow interior forming a storage cavity 2, providing installation space for various functional components. In actual use, to improve comfort and further enhance dust protection, a dustproof cloth or cushion is typically installed on the top surface of the seat plate 1. These dustproof cloths or cushions can be directly laid on the top surface of the seat plate 1, and their size is adapted to fit the top surface of the seat plate 1, thus providing complete coverage.

[0012] On the top surface of the seat plate 1, there are multiple sets of passage components evenly distributed along the depth direction of the seat plate 1. Each set of passage components is connected to the storage cavity 2, providing a channel for the extension of the massage component. Specifically, each passage component includes multiple square through holes 15 distributed parallel to each other along the width direction of the seat plate 1.

[0013] Correspondingly, multiple sets of shielding components are provided on the top wall of the storage cavity 2, distributed along the depth direction of the seat plate 1. Each set of shielding components is installed at the bottom of each set of passage components, which can cover the passage components. Each set of shielding components includes multiple baffles 16 distributed parallel to each other along the width direction of the seat plate 1. The baffles 16 are made of rigid and lightweight material, specifically ABS plastic, polypropylene, or modified polyethylene (ABS plastic is preferred, as it balances sealing performance, impact resistance, and rotational flexibility, avoiding rotational jamming due to excessive weight). The length and width of the baffles 16 are greater than the length and width of each square through hole 15, so that when the baffles 16 are attached to the bottom of the passage components, they can completely cover the square through holes 15, effectively blocking the connection between the storage cavity 2 and the outside. The baffles 16 are rotatably installed, with one end rotatably connected to the edge of the corresponding square through hole 15 on the top wall of the storage cavity 2 via a pin, allowing the baffles 16 to rotate up and down around the pin. It should be noted that the pin-shaft rotation connection is existing technology, and its structure and principle are well known to those skilled in the art, so they will not be described in detail here.

[0014] The storage cavity 2 is equipped with multiple sets of massage components distributed along the seat depth direction of the seat plate 1, and these multiple sets of massage components can move vertically synchronously. Each set of massage components includes multiple massage heads 8, the number and position of which are adapted to the square through hole 15. Since the size of the square through hole 15 needs to accommodate the movement of the massage heads 8, in this embodiment, the diameter of each massage head 8 is smaller than the length and width of the square through hole 15 to ensure that the massage heads 8 can pass smoothly through the through hole. To achieve the vertical movement of the massage components, a motor 5 is bolted to the bottom of the seat plate 1. The motor 5 is a forward and reverse reversible motor (model optional 60YYJ120, rated voltage 220V), which can output power in different directions through forward and reverse rotation, thereby driving subsequent components to achieve different directional movements. The motor 5 serves as the drive source, and its output end is connected to a vertical transmission shaft 6 via a coupling. The other end of the transmission shaft 6 passes through the bottom of the seat plate 1 via a bearing and extends into the storage cavity 2. The side wall of the base plate 1 is equipped with a control button for controlling the forward and reverse rotation of the motor 5 (model LA18-22 optional, electrically connected to the motor 5). It should be noted that the bearing rotation connection is existing technology, and its structure and principle are well known to those skilled in the art, and will not be described in detail here.

[0015] Since the square through-hole 15 in the passage component needs to allow the massage head 8 to extend, the dust cover or seat cushion is made of an elastic and breathable material, such as elastic knitted fabric, spandex blended fabric, or thin memory foam. When the massage head 8 rises, it will exert an upward pushing force on the corresponding position of the dust cover or seat cushion. Due to the elasticity of the material itself, the corresponding position of the dust cover or seat cushion will be naturally pushed open, forming a channel for the massage head 8 to pass through. After the massage head 8 passes through and continues to rise, the edge of the part of the dust cover or seat cushion that has been pushed open can still fit with the outer periphery of the massage head 8, reducing the generation of gaps. When the massage head 8 descends and retracts, the part that has been pushed open will automatically rebound under the action of its own elastic restoring force, and tightly cover the top surface of the seat plate 1 again. It can restore the coverage of the top surface of the seat plate 1 without additional operation, which does not affect the normal operation of the massage component, and can reduce the entry of dust from the gap between the top surface of the seat plate 1 and the outside world when not massaging. At the same time, the elastic material can also improve the soft touch when in contact with the human body.

[0016] Inside the storage cavity 2, multiple vertical connecting shafts 7 are rotatably arranged along the depth direction of the seat plate 1. The number of connecting shafts 7 is the same as the number of massage components. Both ends of the shafts 7 are rotatably connected to the top and bottom walls of the storage cavity 2 via bearings. A transmission assembly is connected between the rod segment of the drive shaft 6 located in the storage cavity 2 and each connecting shaft 7 to achieve power transmission. The transmission assembly includes multiple gears 13 and racks 14. One gear 13 is fixed to the outer periphery of the connecting shaft 7 located at the front end of the seat plate 1, another gear 13 is fixed to the outer periphery of the rod segment of the drive shaft 6 located in the storage cavity 2, and the remaining gears 13 are arranged in pairs and distributed vertically on the outer periphery of each of the remaining connecting shafts 7. The drive shaft 6 is meshed with racks 14 on both the drive shaft 6 and the adjacent connecting shaft 7. The gears 13 on the two adjacent connecting shafts 7 are also meshed with racks 14. Through the meshing of the gears 13 and racks 14, when the motor 5 drives the drive shaft 6 to rotate, it can drive each connecting shaft 7 to rotate synchronously with the drive shaft 6 (the rotation speed is the same as that of the drive shaft 6, ensuring that the massage components rise and fall synchronously).

[0017] Each massage assembly corresponds to each connecting shaft 7. One massage head 8 within each massage assembly has a first moving block 9 welded to its bottom. Each connecting shaft 7 is a threaded rod, and the first moving block 9 has a threaded hole adapted to the connecting shaft 7. Each first moving block 9 is threadedly connected to the corresponding connecting shaft 7 through the threaded hole. Simultaneously, multiple sets of limiting assemblies are fixedly installed in the storage cavity 2, spaced apart along the depth direction of the seat plate 1. These limiting assemblies correspond one-to-one with multiple connecting shafts 7. Each limiting assembly includes multiple limiting rods 11 parallel to the width direction of the seat plate 1. The axial direction of the limiting rods 11 is parallel to the axial direction of the connecting shaft 7. Each limiting rod 11 is a smooth round rod with its two ends fixed to the top and bottom walls of the storage cavity 2, respectively. The bottoms of the remaining massage heads 8 within each massage assembly are each welded to a second moving block 10. The second moving block 10 has a sliding hole adapted to the limiting rod 11, and each second moving block 10 is slidably connected to the corresponding limiting rod 11 through the sliding hole. Furthermore, the first moving block 9 and multiple second moving blocks 10 within each massage assembly are fixedly connected by bolts via connecting rods 12. The connecting rods 12 ensure that the first moving block 9 and the second moving blocks 10 move synchronously, thereby driving all massage heads 8 within the same assembly to move vertically synchronously.

[0018] Each massage component and each shielding component are connected by a connecting component, which includes a connecting rope 3. The connecting rope 3 is made of a flexible material, specifically nylon rope, polyester rope, or steel wire rope (nylon rope is preferred, as it combines flexibility, abrasion resistance, and lightweight, preventing breakage from long-term pulling). Multiple mounting shafts 4 are rotatably arranged within the storage cavity 2, spaced apart along the seat depth direction of the seat plate 1. Each mounting shaft 4 is located on the side of each massage component near the front end of the seat plate 1, 5-10mm (preferably 8mm) from the front end of the massage head 8, ensuring a reasonable lever arm when the connecting rope 3 is pulled, preventing the baffle 16 from getting stuck during rotation. Both ends are rotatably mounted on the side wall of the storage cavity 2 via bearings. One end of each connecting rope 3 is fixed to the massage head 8, and the other end passes around or through the corresponding mounting shaft 4 and is fixed to the end of the baffle 16 furthest from its rotating connection end. The mounting shaft 4 guides the connecting rope 3 to ensure that the tension of the connecting rope 3 is effectively transmitted to the baffle 16.

[0019] Working principle: When the massage function of the seat needs to be activated, the motor 5 is started and controlled to rotate forward. The output end of the motor 5 drives the transmission shaft 6 to rotate forward. The transmission shaft 6, through the meshing of the gear 13 and rack 14 on it, drives the adjacent connecting shaft 7 to rotate. The adjacent connecting shaft 7, in turn, through the engagement of their respective gears 13 and racks 14, drives all the other connecting shafts 7 to rotate synchronously. Since the connecting shaft 7 is a threaded rod, and the first moving block 9 is threadedly connected to the connecting shaft 7, when the connecting shaft 7 rotates, the first moving block 9 moves upward. At the same time, through the connecting rod 12, it drives the second moving block 10 of the same group to slide upward along the limiting rod 11, thereby realizing the synchronous rise of each massage component. During the upward movement of the massage component, the massage head 8 pulls the connecting rope 3. Guided by the mounting shaft 4, the connecting rope 3 causes the baffle 16 to rotate downward around its rotating connection end with the top wall of the storage cavity 2, moving the baffle 16 away from the corresponding square through hole 15. At this time, the massage head 8 can pass through the square through hole 15 and extend out of the seat plate 1 to contact the user's buttocks and perform a massage. When the massage function is not needed, the control motor 5 reverses, and the transmission shaft 6 drives each connecting shaft 7 to rotate in the opposite direction. The first moving block 9 and the second moving block 10 move downward accordingly, and the massage component descends and gradually extends into the storage cavity 2. At this time, the pulling force of the massage head 8 on the connecting rope 3 disappears. Under the combined action of its own weight and the restoring force of the loosened connecting rope 3, the baffle 16 rotates upward around the rotating connection end, gradually approaching and fitting against the bottom of the corresponding square through hole 15, thereby covering the square through hole 15 and isolating the storage cavity 2 from the outside world, preventing dust and other debris from entering the storage cavity 2.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
