Description

Technical Field

[0001] This utility model relates to the field of massage beds, specifically to a massage bed. Background Technology

[0002] Massage beds are typically based on ergonomic principles, precisely conforming to the body's curves to provide a comfortable massage experience. The base of a massage bed is usually available in various materials, including wood, iron, stainless steel, and aluminum alloy. Furthermore, the upholstered structure of a massage bed typically uses a combination of firm and soft foam fillings to ensure comfort and prevent the bed from deforming.

[0003] Massage beds can be categorized into foldable and non-foldable types to suit different space requirements. The bed frame is the main structure of a foldable massage bed, typically made of metal (such as stainless steel or aluminum alloy) or wood. The design of the bed frame emphasizes not only aesthetics and durability but also ease of folding. Metal bed frames are generally more sturdy and lightweight, making them easier to fold and carry; while wooden bed frames offer a more upscale feel and are more environmentally friendly. The bed frames are mostly rectangular in shape and of moderate size to accommodate users of different heights and body types.

[0004] For example, the utility model patent with application number CN202120407392.9, entitled "A Retractable Lumbar Correction Device", has a retractable extension plate at the end of the bed away from the headrest. The extension plate extends horizontally below the bed, resulting in a height difference between the extension plate and the bed, which makes it impossible to provide uniform support for the user's legs. Utility Model Content

[0005] The purpose of this invention is to provide a massage bed that addresses the problem of conventional massage beds having a height difference between the telescopic structure and the bed frame, which prevents them from providing even support to the user's legs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A massage bed includes a bed body and a leg assembly. The leg assembly is located at the tail end of the bed body. A telescopic drive assembly is provided inside the bed body. The telescopic drive assembly includes a drive member and a transmission part that is motively connected to the drive member. The transmission part includes a horizontal transmission position and an inclined transmission position that are interconnected.

[0008] A connector is fixed between the leg assembly and the rotating part. The end of the connector is fixedly connected to the transmission part. The telescopic drive assembly drives the end of the connector to reciprocate between the horizontal transmission position and the inclined transmission position.

[0009] Furthermore, the transmission unit includes a driving wheel, a driven wheel, a transmission wheel, and a transmission component. The driving wheel, driven wheel, and transmission wheel are rotatably mounted inside the bed body via a wheel axle. The driving end of the driving component is drivenly connected to the driving wheel.

[0010] The transmission wheel is located between the driving wheel and the driven wheel. The tops of the transmission wheel and the driven wheel are flush with each other and higher than the top of the driving wheel. The horizontal transmission position is located between the transmission wheel and the driven wheel, and the inclined transmission position is located between the transmission wheel and the driving wheel.

[0011] The transmission component is arranged around the circumference of the driving wheel, the transmission wheel, and the driven wheel, and the end of the connecting component is fixedly connected to the transmission component.

[0012] Furthermore, the number of transmission parts is two sets, with the two sets of transmission parts located on both sides of the leg assembly.

[0013] Furthermore, the end of the bed body facing the leg assembly has a rounded transition surface.

[0014] Furthermore, the bed body is equipped with a backrest mechanism, which includes a backrest and a backrest drive assembly.

[0015] The backrest has a rotating connection at one end, which is rotatably connected to the bed body. The backrest has a drive frame inside, one end of the backrest drive assembly is hinged to the inner bottom of the bed body, and the drive end of the backrest drive assembly is hinged to the drive frame.

[0016] Furthermore, the backrest mechanism and the leg assembly are located at the front and rear ends of the bed body, respectively. One end of the drive frame is provided with a connecting section, which extends toward the leg assembly. The drive end of the backrest drive assembly is hinged to the connecting section.

[0017] Furthermore, the backrest includes a backrest plate and backrest side plates fixed to both sides of the backrest plate, and the drive frame is fixed to the inner side of the backrest side plates.

[0018] The inner side of the bed body is provided with a wheel axle, the transmission part is set on the wheel axle, the backrest side plate is provided with a clearance channel, the end of the wheel axle passes through the clearance channel and extends into the interior of the bed body, and the transmission part is rotatably set at the end of the wheel axle.

[0019] Furthermore, the bed body has an upwardly extending support column inside, which corresponds to the side of the backrest away from the rotating connection part.

[0020] Furthermore, a massage channel is provided on the backrest, and a slide rail is fixed inside the drive frame, the extension direction of the slide rail being the same as the extension direction of the massage channel.

[0021] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] The drive unit drives the leg assembly to extend forward or retract and store it through the transmission unit and the connecting unit. At the same time, the horizontal transmission unit moves the leg assembly horizontally, and the tilting transmission unit moves the leg assembly vertically. This allows the leg assembly to extend forward while lowering its height vertically, making it flush with the top surface of the bed body, thus providing even support for the user's legs, waist and other parts.

[0036] Example

[0037] Please refer to Figure 1-5 As shown, this embodiment provides a massage bed, including a bed body 1 and a leg assembly 2, with the leg assembly 2 located at the rear end of the bed body 1. The bed body 1 contains a telescopic drive assembly 11, which includes a drive member 111 and a transmission part 112 driven and connected to the drive member 111. The transmission part 112 includes a horizontal transmission position 1121 and an inclined transmission position 1122 connected to each other. A connecting member 24 is fixed between the leg assembly 2 and the rotating part, with the end of the connecting member 24 fixedly connected to the transmission part 112. The telescopic drive assembly 11 drives the end of the connecting member 24 to reciprocate between the horizontal transmission position 1121 and the inclined transmission position 1122.

[0038] The drive unit 111 drives the leg assembly 2 to extend forward or retract backward through the transmission unit 112 and the connector 24. At the same time, the horizontal transmission unit moves the leg assembly 2 horizontally, and the tilting transmission unit moves the leg assembly 2 vertically. This allows the leg assembly 2 to extend forward while lowering its height vertically, making it flush with the top surface of the bed body 1, thus providing uniform support for the user's legs, waist, and other parts.

[0039] Please refer to Figure 2 and Figure 4 As shown, specifically, the transmission unit 112 includes a driving wheel 1123, a driven wheel 1125, a transmission wheel 1124, and a transmission member 1126. The driving wheel 1123, driven wheel 1125, and transmission wheel 1124 are rotatably mounted inside the bed body 1 via a wheel axle 141. The driving end of the driving member 111 is drivenly connected to the driving wheel 1123. The transmission wheel 1124 is located between the driving wheel 1123 and the driven wheel 1125. The tops of the transmission wheel 1124 and the driven wheel 1125 are flush with each other and higher than the top of the driving wheel 1123. A horizontal transmission position 1121 is located between the transmission wheel 1124 and the driven wheel 1125, and an inclined transmission position 1122 is located between the transmission wheel 1124 and the driving wheel 1123. The height difference between the transmission wheel 1124 and the drive wheel 1123 forms an inclined transmission position 1122, which drives the leg assembly 2 vertically. This ensures that, in use, the top surface of the leg assembly 2 is at the same level as the top surface of the bed body 1, providing better support for the user. The transmission component 1126 is wound around the drive wheel 1123, transmission wheel 1124, and driven wheel 1125, and the end of the connecting component 24 is fixedly connected to the transmission component 1126. In this embodiment, the drive wheel 1123, transmission wheel 1124, and driven wheel 1125 are all gears, and the transmission component 1126 is a chain wound around the drive wheel 1123, transmission wheel 1124, and drive wheel. Similarly, other transmission structures, such as a conveyor belt, can also be used.

[0040] In this embodiment, there are two sets of transmission units 112, located on both sides of the leg assembly 2. The driving wheels 1123, transmission wheels 1124, and driven wheels 1125 of the two sets of transmission units 112 are rotatably mounted on the inner side of the bed body 1 via axle 141. The two sets of transmission units 112 on both sides drive the leg assembly 2, ensuring better stability during movement. In this embodiment, the drive unit 111 is a leg drive motor. The drive end of the leg drive motor is connected to a drive handle 1111, which extends to both sides and is fixedly connected to the driving wheels 1123 on both sides, synchronously driving the two sets of transmission units 112.

[0041] The end of the bed body 1 facing the leg assembly 2 has a rounded transition surface. When the connecting piece 24 of the leg assembly 2 moves on the inclined transmission position 1122, the end of the leg assembly 2 abuts against the rounded transition surface and descends. The rounded transition surface provides stable support for the leg assembly 2, ensuring that the leg assembly 2 can descend smoothly to the lowest position and be flush with the top surface of the bed body 1. This avoids the leg assembly 2 from descending vertically, causing collisions between the leg assembly 2 and the ground, affecting the service life of the leg assembly 2 and the connection stability of the internal telescopic drive component 11. In this embodiment, the leg assembly 2 includes a horizontal leg plate 21, a rounded leg plate 22, and a vertical leg plate 23 connected in sequence. The curvature of the rounded leg plate 22 is the same as the curvature of the rounded transition surface, ensuring that the leg assembly 2 can fit tightly against the bed body 1 in the folded state, reducing the folded size and improving folding convenience. At the same time, the rounded leg plate 22 protects the user's legs, preventing leg bumps caused by large-angle turns, which would affect use.

[0042] In this embodiment, the bed body 1 includes a hip assembly 12, a base plate 13, and side plates 14. The hip assembly 12 includes a horizontal seat plate 121, an arc-shaped seat plate 122, and a vertical seat plate 123 connected in sequence. The top surface of the arc-shaped seat plate 122 is the aforementioned arc transition surface. The bottom of the vertical seat plate 123 is fixedly connected to the base plate 13. The side plates 14 are located on both sides of the hip assembly 12, and the bottom of the side plates 14 is fixedly connected to the side of the base plate 13. In the folded state, the horizontal leg plate 21 is fitted onto the horizontal seat plate 121.

[0043] Please refer to Figure 1 and Figure 3 As shown, specifically, the bed body 1 is provided with a backrest mechanism 3, which includes a backrest 31 and a backrest drive assembly 32. In this embodiment, the horizontal seat plate 121 has an installation notch 1212 on the side away from the leg assembly 2, and the backrest mechanism 3 is disposed in the installation notch 1212. The end of the backrest 31 is provided with a rotating connection part 311, which is rotatably connected to the bed body 1. In this embodiment, the rotating connection part 311 extends to both sides of the horizontal seat plate 121, and the two sides of the horizontal seat plate 121 are provided with rotating handles 1211. The drive handles pass through the rotating connection part 311 to realize the flipping of the backrest 31. The backrest 31 has a drive frame 312 inside, one end of the backrest 31 drive assembly is hinged to the inner bottom of the bed body 1, and the drive end of the backrest 31 drive assembly is hinged to the drive frame 312. The backrest 31 drive assembly drives the backrest 31 to flip along the wheel axle 141 of the horizontal seat plate 121 via the drive frame 312, so as to achieve tilting back or horizontal reclining use, adapting to more usage needs.

[0044] In this embodiment, the backrest mechanism 3 and the leg assembly 2 are located at the front and rear ends of the bed body 1, respectively. One end of the drive frame 312 has a connecting section 3121 extending towards the leg assembly 2. The drive end of the backrest 31 drive assembly is hinged to the connecting section 3121. The connecting section 3121 extending towards the leg assembly 2 in the drive frame 312 increases the length of the power arm of the backrest 31 drive assembly, facilitating better driving of the backrest 31 to flip. In this embodiment, the backrest 31 drive assembly includes a telescopic cylinder. The bottom end of the telescopic cylinder is hinged to the base plate 13, and the drive end of the telescopic cylinder is hinged to the connecting section 3121. Movement of the telescopic cylinder drive end allows the backrest 31 to flip upwards at an angle for back massage or to lie horizontally for the user. Similarly, other telescopic drive structures can also be used.

[0045] Specifically, the backrest 31 includes a backrest plate 313 and backrest side plates 314 fixed on both sides of the backrest plate 313. The drive frame 312 is fixed on the inner side of the backrest side plate 314. A wheel axle 141 is provided on the inner side of the bed body 1, and a transmission part 112 is mounted on the wheel axle 141. That is, three wheel axles 141 are provided on the inner side of the side plate 14. The driving wheel 1123, driven wheel 1125, and transmission wheel 1124 of the transmission part 112 on the same side are rotatably mounted on the three wheel axles 141 respectively. Please refer to the appendix. Figure 2 and Figure 4 The backrest side panel 314 has a clearance channel 3141. The end of the axle 141 passes through the clearance channel 3141 and extends into the bed body 1. The transmission part 112 is rotatably mounted on the end of the axle 141. The clearance channel 3141 makes way for the axle 141, preventing collision with the axle 141 during the backrest 31's rotation. Furthermore, the clearance channel 3141 is an arc-shaped channel, or similarly, a gate-shaped channel, effectively avoiding the axle 141 while reducing the weight of the backrest 31 and reducing energy loss.

[0046] In this embodiment, the bed body 1 has an upwardly extending support column 131 inside, specifically, the support column 131 is fixed to the base plate 13. The support column 131 corresponds to the side of the backrest 31 away from the rotating connection part 311. The support column 131 abuts against the bottom of the backrest side plate 314, supporting the end of the backrest 31 away from the leg assembly 2, reducing the magnitude of the force applied by the backrest 31 drive assembly under leverage when the backrest 31 is subjected to force from above, thus protecting the backrest 31 drive assembly. Furthermore, a backrest base plate 315 is provided on the bottom surface of the backrest 31 and the side plate 14. The backrest base plate 315 effectively increases the contact area between the backrest 31 and the support column 131, enabling the support column 131 to provide greater and more stable support for the backrest 31, further improving the stability of the backrest 31 and the protection effect on the backrest 31 drive assembly.

[0047] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, a massage channel 3131 is provided on the backrest 31. Specifically, the massage channel 3131 is located on the backrest plate 313. The extension direction of the massage channel 3131 is the same as the overall length direction of the massage bed. A slide rail (not shown in the attached figure) is fixed inside the drive frame 312, and the extension direction of the slide rail is the same as the extension direction of the massage channel 3131. The slide rail is used for installing massage equipment, facilitating comprehensive massage of the user's neck and back.
