Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Combination such as Figures 1-12As shown, this utility model embodiment provides a massage chair with sliding armrests, including a main unit 1 and two side plates 13 disposed on both sides of the main unit 1. The main unit 1 includes a back frame 11 and a seat frame 12, with the two side plates 13 disposed on both sides of the seat frame 12. The massage chair also includes two armrests 2, which are slidably disposed on the side plates 13. The two armrests 2 have a first position a, which slides towards each other and close together, and a second position b, which slides away from each other and close apart. The width L2 of the massage chair when the two armrests 2 are in the first position is smaller than the width L1 of the massage chair when the two armrests 2 are in the second position. In this embodiment, the back frame 11 is rotatably disposed on the seat frame 12, and the side plates 13 are respectively disposed on both sides of the seat frame 12. The armrests 2 are slidably disposed on the side plates 13. At least one slider guide rail structure 3 is disposed between the armrests 2 and the side plates 13. The two armrests 2 rely on this slider guide rail structure 3 to slide in the width direction of the massage chair, thereby adjusting the overall width of the massage chair. In terms of packaging, the width of the massage chair was adjusted to be narrower, reducing the packaging width. At the same time, compared with separate packaging, the utilization rate of the container volume was improved.

[0018] Furthermore, in one instance, such as Figure 3 As shown, the handrail 2 is slidably mounted on the side plate 13 via at least one slider guide rail structure 3. To improve the smoothness of the handrail 2's sliding, the handrail 2 is provided with multiple slider guide rail structures 3 arranged at intervals. Specifically, the slider guide rail structure 3 includes a guide rail 31 mounted on the side plate 13 and a slider 21 mounted on the handrail 2, with the slider 21 slidably mounted on the guide rail 31. Alternatively, the configuration can be reversed, with a guide rail on the handrail and a slider on the side plate, as long as relative sliding is achieved.

[0019] Furthermore, in one instance, such as Figure 3 , 9 As shown in Figure 10, a position detection sensor is provided on the slider guide rail structure 3 to detect whether the two handrails are in the first position a or the second position b. Specifically, the position detection sensor can be a combination of a magnet 211 and a Hall sensor 221, an optocoupler sensor, or a micro switch, etc., to achieve position detection. Taking a magnet and Hall sensor as an example, a magnet 211 is provided on the slider 21, and a Hall sensor plate 221 is provided on the guide rail 22. The slider 21 can be fixed to the handrail 2 or the side plate 13, and the guide rail 22 can be fixed to the side plate 13 or the handrail 2. The slider 21 slides within the guide rail 22. Figure 11 As shown, the micro switch 35 is fixed to the side plate 13 together with the guide rail 22. It can be configured such that when both left and right handrails 2 are at their widest points simultaneously, the boss on the slider 21 contacts the micro switch 35 on the side plate 13, thus activating the micro switch signal. Figure 11As shown in the right-hand diagram. At this point, the control device determines that armrest 2 has been pulled open to both sides, and the massage chair can perform massage actions normally. Conversely, if... Figure 11 As shown in the left figure, when armrest 2 is at its widest point, the protrusion 37 on slider 21 and the microswitch 35 on side panel 13 are far apart, resulting in no signal connection and preventing the massage from starting. If one armrest 2 is pulled to its widest point while the other armrest 2 is not, the microswitches 35 on both sides will not be triggered simultaneously, and the massage will still not start. Figure 12 As shown, the optocoupler switch 36 is fixed to the side plate 13 together with the guide rail 22. It can be configured such that when both left and right handrails 2 are at their widest points simultaneously, the boss on the slider 21 contacts the optocoupler switch 36 on the side plate 13, thus activating the optocoupler switch signal. Figure 12 As shown in the left-hand image. At this point, the center panel indicates the armrests have been pulled open to the sides, allowing the massage chair to perform normal massage actions. Conversely, if the armrests are not pulled open... Figure 12 As shown in the diagram on the right, when the armrest 2 is at its widest point, the protrusion 37 on the slider 21 and the optocoupler switch 36 on the side panel 13 are far apart, and there is no signal connection, so the massage cannot be started. If one armrest 2 is pulled to its widest point but the other armrest 2 is not pulled to its widest point, that is, the optocoupler switch 36 does not detect the trigger signal together, the massage cannot be started at this time.

[0020] Specifically, such as Figure 3 , 8 As shown in Figure 9, the guide rail 22 is arranged along the width direction of the massage chair. The guide rail 22 includes a base plate 311 and two baffles 312 and a limiting plate 314 connected to both sides of the base plate 311. The base plate 311 is fixedly connected to the baffles 312 and the limiting plate 314. The top ends of the two baffles 312 include opposing limiting strips 3121, and a guide groove 313 is formed between the limiting strips 3121 and the base plate 311. The slider 21 slides within the guide grooves 313 on both sides. The slider 21 includes a slider body 321 and two lugs 322 disposed on both sides of the slider body. The two lugs 322 are slidably connected to the two guide grooves 313 respectively. The slider body 321 is fixedly connected to the armrest 2.

[0021] Working principle: such as Figures 1-10 As shown, in the initial state (widest state, i.e., second position b), the width of the massage chair armrests on both sides is L1, as follows. Figure 1 As shown, slider 21 is at end A of guide groove 313 (e.g. Figure 6 Pushing the two handrails 2 inward, the slider 21 can move within the guide groove 313, moving the handrail 2 from the second position b to the first position a, that is, to the inner side (narrowest point), and simultaneously moving the other handrail. At this time, the width on both sides is L2, as shown. Figure 2 The slider is at end B of the guide groove 313 (e.g. Figure 7Since L2 is smaller than L1, the width of the armrests on both sides becomes smaller, thus reducing the overall width of the massage chair.

[0022] The massage chair may also include a control device, which can be configured such that when both armrests 2 are at their widest points simultaneously, the magnet 211 inside the slider 21 and the Hall effect sensor 221 on the guide rail 22 are connected, and the signal is transmitted to the control device. Figure 10 At this point, the control device determines that the armrests have been pulled open to both sides and are in the second position b. The massage chair can then perform the massage action normally. Conversely, if the control device detects that the armrests are in the first position a, the massage action cannot be started. If one armrest 2 is pulled to its widest position while the other armrest 2 is not pulled open to its widest position, the magnet and Hall signal are not connected, and the massage action still cannot be started.

[0023] The massage chair provided in this embodiment of the invention achieves reduced packaging size and material usage, thereby increasing the overall cabinet capacity. It also enables the complete delivery of a large massage chair to the home, saving on after-sales installation costs and reducing installation quality risks. Based on the variable width armrests, sensors are added to determine the armrest position through signal changes, ensuring the massage is activated only when the armrests are in the correct position. This increases protection for both the massage chair and the user, and enhances its intelligent features.

[0024] like Figure 3 and 9 As shown, it also includes a knob device 23, which is used to operably lock the handrail 2 to a first position a or a second position b. The knob device 23 includes a first fixing hole 231 provided on the handrail 2, a pin 232 inserted into the first fixing hole 231, and a knob 233; the knob 233 is provided on the handrail 2 through a knob fixing plate 234, and the knob 233 controls the pin 232 to extend or retract in the first fixing hole 231 when turned. When retracted, the handrail can slide back and forth, and when extended, it can be fixed in place. In this way, the same knob locking device can be used to fix two handrail states.

[0025] Furthermore, in this embodiment, each handrail 2 is provided with multiple spaced slider guide rail structures 3, making the sliding more stable and reliable.
