Description

Technical Field

[0001] This utility model generally relates to the field of seating technology, and specifically to an intelligent massage lumbar support and seat. Background Technology

[0002] A lumbar support is a component on seating used to assist in supporting the user's lower back. When people sit for long periods of time studying or working, the lower back muscles are prone to strain, which can potentially lead to a series of lumbar spine diseases. Using a lumbar support can effectively relieve lower back fatigue and also help users correct their posture.

[0003] Furthermore, with the ever-increasing demands of users, a lumbar support with massage function has emerged on the market. This type of lumbar support features a massage device on its main body, equipped with multiple massage heads that can rotate in multiple directions. While the lumbar support is providing support, the massage heads massage the user's lower back, more effectively relieving fatigue and enhancing comfort. Moreover, the massage device and the main body of this type of lumbar support are connected via an air cushion. Users can press a button on the lumbar support to inflate or deflate the air cushion, causing the massage device to move forward or inward according to its expansion and contraction. This allows users to adjust the position of the massage device according to their needs, offering greater freedom of movement.

[0004] However, the above solution has the following problems: the air cushion is relatively soft, which makes it easy for the air cushion to deform when the air cushion is pushed and pulled or when the massage device is squeezed by the waist. This causes the massage device to become tilted, making it unable to slide smoothly back and forth relative to the lumbar support body or fit the user's waist. In other words, the depth adjustment operation of the massage device is not stable. Summary of the Invention

[0005] In view of the aforementioned defects or deficiencies in the existing technology, it is desirable to provide an intelligent massage lumbar support and seat. This device utilizes the expansion and contraction of an air cushion to drive the massage unit to slide back and forth relative to the support body. The sliding adjustment is simple, and the sliding depth of the massage unit can be controlled by adjusting the air intake or exhaust volume, resulting in high adjustment precision. Furthermore, in addition to being constrained by the connecting groove, the massage unit is also constrained by multiple sets of guide protrusions and guide grooves. This prevents the massage unit from tilting when sliding within the connecting groove or when subjected to pressure from the user's lower back, thus maintaining a stable posture and providing robust support for the user's lower back, effectively improving comfort.

[0006] The effect of this utility model is achieved as follows: In a first aspect, this application provides an intelligent massage lumbar support, including a lumbar support body, a massage device, and an air cushion. The front end of the lumbar support body is recessed to form a connecting groove. The air cushion is disposed at the bottom of the connecting groove, and the front end of the air cushion abuts against the massage device. The air cushion inhales or deflates through an inflation component, thereby driving the massage device to slide back and forth along the connecting groove. A guide structure is provided between the lumbar support body and the massage device. The guide structure includes multiple sets of mutually sliding and cooperating guide protrusions and guide grooves. Multiple guide protrusions are disposed in one of the side wall of the lumbar support body and the groove wall of the connecting groove. Multiple guide grooves are formed in the other of the side wall of the lumbar support body and the groove wall of the connecting groove. The guide grooves extend in a front-back direction. When the massage device slides back and forth along the connecting groove, the guide protrusions slide back and forth along the guide groove, so that the massage device can maintain the same posture during the sliding process.

[0007] Furthermore, the side wall of the lumbar support body is provided with two sets of symmetrical guide protrusions, and the groove wall of the connecting groove is correspondingly recessed to form two sets of symmetrical guide grooves. This ensures that the massage device is constrained by the guide protrusions and guide grooves no matter which direction it tilts, thereby ensuring that the massage device can maintain the same posture and has strong stability.

[0008] Furthermore, the massage device has a hollow shell structure. The internal cavity of the massage device forms a first receiving groove, within which a motor and a worm gear vertically connected to the motor are installed. A set of symmetrical gear transmission components meshes with the worm gear, each including a first gear. The motor is configured to drive the worm gear to rotate circumferentially, thereby causing the first gears on both sides to rotate synchronously in opposite directions. The massage device also includes two massage elements on the front side. The first gears on both sides and the massage elements are connected by transmission rods, allowing the massage elements to rotate synchronously with the first gears. By using a single motor to drive the massage elements on both sides of the massage device to rotate synchronously in opposite directions, not only is the transmission method simple, but the two massage elements can simultaneously massage both sides of the user's waist, resulting in greater comfort.

[0009] Furthermore, the massage device also includes a front-mounted massage component and a heating module within it, configured to adjust the temperature of the massage component. This combination of physical massage and heating conforms to ergonomics and modern rehabilitation medicine, further enhancing the comfort of the smart lumbar support.

[0010] Furthermore, the massage device also includes a front-side massage component with multiple massage heads arranged circumferentially on it. These massage heads vary in size, making the massage device more ergonomic and providing a more comfortable massage experience.

[0011] Furthermore, the lumbar support body has a hollow shell structure, with the internal cavity forming a second receiving groove. An air pump and multiple air valves are installed within this groove. Two air vents, left and right, are located on the rear side of the air cushion. These vents pass through the lumbar support body and connect to the air pump and air valves. The air pump is configured to inflate the air cushion through the air vents, and the air valves are configured to control the inflation and deflation of the air cushion. This simplifies the inflation and deflation operations of the air cushion and allows for more precise control of the inflation and deflation volumes, thereby resulting in higher accuracy in adjusting the sliding depth of the massage device.

[0012] Furthermore, the lumbar support body is also equipped with a Bluetooth control module, which is configured to exchange data with a mobile APP or WeChat mini-program to remotely control the massage device to turn on or off and the inflation component to inflate or deflate. Users can remotely operate various functions of the smart massage lumbar support, which is not only easy to adjust, but also allows for more precise adjustments via the APP or mini-program.

[0013] Furthermore, the lumbar support itself is equipped with an adjustment switch, which is configured to turn the smart massage lumbar support on or off. In addition to remotely adjusting the smart massage lumbar support via Bluetooth module, users can also directly adjust the smart massage lumbar support using the adjustment switch. That is, the smart massage lumbar support has at least two adjustment methods, and users can freely choose the adjustment method according to their own usage habits and usage environment, making operation more convenient.

[0014] Secondly, this application provides a seat, including a backrest and a lumbar support assembly. The lumbar support assembly includes an adaptive lumbar support, an elastic lumbar support, and a smart massage lumbar support. Each of the adaptive, elastic, and smart massage lumbar supports has a mounting portion at its rear end. The backrest includes a support portion extending forward from the center, and the support portion and the mounting portion are detachably connected, allowing the front end of the backrest to be connected to one of the adaptive, elastic, or smart massage lumbar supports. Users can freely choose the lumbar support according to their needs and the environment, offering greater flexibility.

[0015] Furthermore, the support and mounting parts are detachably connected by screws. A mounting groove is recessed at the rear of the support, and screws pass through the bottom of the groove and are screwed into the mounting part. A cover plate is also provided on the support to conceal the mounting groove. This not only facilitates the installation and removal of the backrest and lumbar supports, but also prevents the connection marks between the backrest and lumbar supports from being visible, thus giving the seat better overall integrity and aesthetics.

[0016] The intelligent massage lumbar support and seat provided in this application utilizes the expansion and contraction of an air cushion to drive the massage device to slide back and forth relative to the lumbar support body. The sliding adjustment is simple, and the sliding depth of the massage device can be controlled by adjusting the air intake or exhaust volume, resulting in high adjustment precision. Furthermore, in addition to being constrained by the connecting groove, the massage device is also constrained by multiple sets of guide protrusions and guide grooves. This prevents the massage device from tilting when sliding within the connecting groove or when subjected to pressure from the user's lower back, thus maintaining a stable posture and providing robust support for the user's lower back, effectively enhancing comfort. Furthermore, the lumbar support components include three types of lumbar supports with different shapes and functions: adaptive lumbar support, elastic lumbar support, and intelligent massage lumbar support. All of them are equipped with mounting parts and can be detachably connected to the back support, allowing users to freely choose the lumbar support according to their own needs and usage environment, thus providing greater freedom.

Detailed Implementation

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0020] Please refer to the attached document. Figure 1-9 This application provides an intelligent massage lumbar support, including a lumbar support body 1, a massage device 2, and an air cushion 3. The front end of the lumbar support body 1 is recessed to form a connecting groove 101. The air cushion 3 is disposed at the bottom of the connecting groove 101, and the front end of the air cushion 3 abuts against the massage device 2. The air cushion 3 inhales or deflates through an inflation component, thereby driving the massage device 2 to slide back and forth along the connecting groove 101. A guide structure is provided between the lumbar support body 1 and the massage device 2. The guide structure includes multiple sets of mutually sliding and cooperating guide protrusions 210 and guide grooves 102. Multiple guide protrusions 210 are disposed in one of the side wall of the lumbar support body 1 and the groove wall of the connecting groove 101. Multiple guide grooves 102 are formed in the other of the side wall of the lumbar support body 1 and the groove wall of the connecting groove 101. The guide grooves 102 extend in the front-back direction. When the massage device 2 slides back and forth along the connecting groove 101, the guide protrusions 210 slide back and forth along the guide grooves 102, so that the massage device 2 can maintain the same posture during the sliding process.

[0021] In this embodiment, the expansion and contraction of the air cushion 3 causes the massage device 2 to slide back and forth relative to the lumbar support body 1. The sliding adjustment operation is simple, and the sliding depth of the massage device 2 can be controlled by controlling the air intake or exhaust volume, resulting in high adjustment precision. In addition to being constrained by the connecting groove 101, the lumbar support body 1 is also constrained by multiple sets of guide protrusions 210 and guide grooves 102. This makes it less likely for the massage device 2 to tilt when sliding within the connecting groove 101 or when subjected to pressure from the user's waist, thus maintaining a stable posture to support the user's waist. This provides strong stability and effectively improves comfort.

[0022] Please refer to the appendix. Figure 1 The front end of the lumbar support body 1 is covered with a mesh fabric 8. The mesh fabric 8 is not only breathable and has good elasticity, thus providing users with more comfortable elastic support, but also covers the massage device 2, making the smart massage lumbar support more integrated and beautiful in appearance.

[0023] Please refer to the attached document. Figure 3 In some embodiments of this application, two sets of symmetrical guide protrusions 210 are provided on the side wall of the waist support body 1, and two sets of symmetrical guide grooves 102 are correspondingly recessed on the groove wall of the connecting groove 101.

[0024] In this embodiment, by setting two sets of symmetrical guide protrusions 210 and guide grooves 102, the massage device 2 can be constrained by the guide protrusions 210 and guide grooves 102 no matter which direction it tilts, thereby ensuring that the massage device 2 can maintain the same posture and has strong stability.

[0025] Of course, in other embodiments of this application, the number of guide protrusions 210 and connecting grooves 101 between the lumbar support body 1 and the connecting groove 101 can be one, three, four, etc.

[0026] Please refer to the attached document. Figure 4-6 In some embodiments of this application, the massage device 2 is a hollow shell structure. The cavity inside the massage device 2 forms a first receiving groove 201. A motor 230 and a worm gear 240 vertically connected to the motor 230 are disposed in the first receiving groove 201. A set of gear transmission components symmetrically connected to the left and right are meshed on the worm gear 240. The gear transmission components include a first gear 250. The motor 230 is configured to drive the worm gear 240 to rotate around its own circumference and drive the first gears 250 on the left and right sides to rotate synchronously in opposite directions. The massage device 2 also includes two massage elements 220 on the front side. The first gears 250 on the left and right sides and the massage elements 220 are connected by a transmission rod 251, so that the massage elements 220 rotate synchronously with the first gears 250.

[0027] In this embodiment, a motor 230 drives a worm gear 240 to rotate, which in turn drives the gear transmission components on both sides to rotate synchronously in opposite directions. This drives the massage pieces 220 on the left and right sides of the massage device 2 to rotate synchronously in opposite directions. Not only is the transmission method simple, but the two massage pieces 220 can massage the user's waist on both sides at the same time, resulting in greater comfort.

[0028] Preferably, please refer to the appendix. Figure 4-6 The massage device 2 has a split structure, including a first housing 2a and a second housing 2b joined together. The gap between the first housing 2a and the second housing 2b after joining forms a first receiving groove 201. The gear transmission assembly also includes a second gear 260 and a third gear 270. The two second gears 260 are respectively disposed on the left and right sides of the worm gear 240 and are both meshed with the worm gear 240. The two second gears 260 on both sides are driven by the worm gear 240 to rotate synchronously in opposite directions. The third gear 270 is disposed between the first gear 250 and the second gear 260, and the three are meshed with each other, so that when the second gear 260 rotates, the third gear 270 is driven to rotate by the second gear 260, thereby driving the first gear 250 to rotate synchronously. The transmission rod 251 passes through the first housing 2a and is connected to the massage element 220, so that the massage element 220 can rotate together with the first gear 250. Thus, the massage elements 220 on the left and right sides are driven to rotate synchronously in opposite directions, and the transmission process is very stable.

[0029] Please refer to the attached document. Figure 3 In some embodiments of this application, the massage device 2 further includes a front massage element 220, and a heat therapy module is provided inside the massage device 2. The heat therapy module is configured to adjust the temperature of the massage element 220.

[0030] In this embodiment, the temperature of the massage component 220 is adjusted by a heating module, allowing the massage component 220 to heat the massaged area during the massage process. This promotes blood circulation in the user's lower back, effectively relieving muscle fatigue and pain. Furthermore, the user can freely adjust the temperature of the massage component 220 according to their needs, offering a high degree of freedom. This intelligent massage lumbar support combines physical massage and heating, conforming to ergonomics and modern rehabilitation medicine, further enhancing the comfort of the intelligent lumbar support.

[0031] Preferably, the heating module has at least three adjustable temperature levels, including a low level of 40°C, a medium level of 45°C, and a high level of 50°C, offering a high degree of freedom. Users can turn the heating module on and off with a single button via a switch on the smart massage lumbar support or via Bluetooth remote control, making the adjustment operation very convenient.

[0032] Please refer to the attached document. Figure 3In some embodiments of this application, the massage device 2 further includes a front massage member 220, on which a plurality of massage heads 221 are provided along the circumferential direction, and the plurality of massage heads 221 are of different sizes.

[0033] In this embodiment, the human body's waist bends forward, meaning the rear end of the waist is curved. If the front end of the massage element 220 were vertical, it wouldn't fit and press the waist effectively. Therefore, by providing multiple massage heads 221 of varying sizes on the massage element 220, the massage surface formed by the front ends of these heads is curved, allowing for a better fit to the user's waist. Furthermore, as the massage element 220 rotates, the multiple massage heads 221 rotate circumferentially, causing the massage surface to continuously change, resulting in better pressure on the user's waist. Thus, the massage device 2 is more ergonomic and provides greater massage comfort.

[0034] Please refer to the attached document. Figure 7 In some embodiments of this application, the lumbar support body 1 is a hollow shell structure. The cavity inside the lumbar support body 1 forms a second receiving groove 103. An air pump 110 and multiple air valves 120 are disposed in the second receiving groove 103. Two air ports 310 are disposed on the rear side of the air cushion 3. The air ports 310 pass through the lumbar support body 1 and are connected to the air pump 110 and the air valves 120. The air pump 110 is configured to inflate the air cushion 3 through the air ports 310, and the air valves 120 are configured to control the inflation amount and deflate the air cushion 3. This makes the inflation and deflation operations of the air cushion 3 simple, and the control of the inflation and deflation amounts more precise, thereby making the sliding depth adjustment accuracy of the massage device 2 higher.

[0035] Preferably, the lumbar support body 1 is a split structure, including a third shell 1a and a fourth shell 1b spliced ​​together. The gap between the third shell 1a and the fourth shell 1b forms a second receiving groove 103. The third shell 1a has two clearance openings 104 on the left and right. The air inlet 310 passes through the clearance opening 104 and extends into the second receiving groove 103 and is connected to the air pump 110 and the air valve 120.

[0036] In some embodiments of this application, the lumbar support body 1 is also provided with a Bluetooth control module, which is configured to exchange data with a mobile APP or WeChat mini program, thereby remotely controlling the massage device 2 to turn on or off and the inflation component to inflate or deflate.

[0037] In this embodiment, with the help of a Bluetooth module, users can remotely control various functions of the smart massage lumbar support. Not only is the adjustment operation simple, but users can also make more precise adjustments on the APP or mini-program. For example, when adjusting the depth of the massage device 2, by continuously pressing the "+" and "-" buttons on the APP or mini-program, the inflation component can continuously inflate or deflate the air cushion 3, so that the massage device 2 can slide continuously in the current direction until the user adjusts it to a suitable position. When the user releases the button, the massage device 2 can be fixed in the current position.

[0038] Preferably, the Bluetooth module can also adjust other functions of the smart massage lumbar support, such as adjusting the on / off state and intensity of the heat therapy module, adjusting the rotation mode and speed of the massage element 220, and controlling the extension and retraction of the massage head 221 to adjust the massage intensity, etc.

[0039] Please refer to the attached document. Figure 7 In some embodiments of this application, the lumbar support body 1 is also provided with an adjustment switch 130, which is configured to adjust the smart massage lumbar support to be turned on or off. In addition to remotely adjusting the smart massage lumbar support via Bluetooth module, users can also directly adjust the smart massage lumbar support via the adjustment switch 130. That is, the smart massage lumbar support has at least two adjustment methods, and users can freely choose the adjustment method according to their own usage habits and usage environment, making operation more convenient.

[0040] Preferably, a lithium battery 140 is provided on the third housing 1a. The lithium battery 140 is configured as the power source for the smart massage lumbar support and can store a large amount of electricity, so that the smart massage lumbar support does not need to be charged all the time during use, making it more convenient to use.
