The motor drives the moving part to move back and forth along the slide rail, and at the same time drives the massage component to move. The backrest massage device of the existing massage cushion has the following problems: Since the motor control module is arranged inside the moving part, it is necessary to connect the motor control module electrically through a wire, supply power to the motor control module and the motor, and communicate and connect the motor control module with the human-computer interaction module (such as a key module or a touch screen module). The back and forth movement of the moving part can easily cause the wire to be damaged, entangled, or even disconnected, affecting the normal use of the backrest massage device. In addition, the motor control module is arranged inside the moving part, which not only takes up space, but also increases the total weight of the moving part, increases energy consumption, and brings many inconveniences to the maintenance work of the motor control module.
[0003] In addition, in order to limit the travel of the moving parts, Hall sensors are usually installed inside the moving parts, and magnets are installed at both ends of the slide rails to cooperate with the Hall sensors. However, Hall sensors are expensive and easily affected by temperature, magnetic fields, etc., and require additional calibration and debugging, which brings many inconveniences to the production, assembly, and subsequent maintenance of the backrest massage device.

[0024] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.
[0025] like Figures 1 to 4 The utility model discloses a massage device, including a slide rail 2, a moving component 3 and a massage component 4. The upper ends of the two slide rails 2 are fixedly connected to the same upper crossbeam 1, and the lower ends are fixedly connected to the same lower crossbeam 5, so that the two slide rails 2 are arranged parallel to each other. The moving component 3 is equipped with a massage component 4. The two sides of the moving component 3 are slidably arranged on the two slide rails 2 respectively. A transmission rack 21 is provided on one side of the slide rail 2. A motor 31 is assembled inside the moving component 3, and the output shaft of the motor 31 is connected to the transmission rack 21 through a gear set, so as to make the moving component 3 slide along the slide rail 2. Of course, the motor 31 is also used to drive the massage component 4.
[0026] like Figures 1 to 4The massage device further includes a power supply rail 61 and a motor control module 7. The power supply rail 61 is fixed with a plurality of first conductive members 611. The moving part 3 is fixed with a plurality of second conductive members 621, and the second conductive members 621 are electrically connected to the motor 31. The motor control module 7 is arranged outside the moving part 3, one side of the moving part 3 is slidably arranged on the power supply rail 61, and the second conductive member 621 is slidably abutted against the first conductive member 611, so that the motor control module 7 is electrically connected to the motor 31.
[0027] More specifically, a sleeve 62 is provided on one side of the outer shell of the power supply slide rail 61, and the power supply slide rail 61 can be slidably inserted into the sleeve 62, and two long strips of first conductive members 611 are fixedly provided on one end surface of the power supply slide rail 61. The sleeve 62 is fixedly provided with two second conductive members 621 on the opposite side of the first conductive member 611, and the second conductive member 621 is electrically connected to the motor 31 through the built-in wire (not shown in the figure) of the moving part 3. The two second conductive members 621 correspond one by one and can slidably abut against the two first conductive members 611. The power supply slide rail 61, the first conductive member 611, the second conductive member 621 and the sleeve 62 form the power supply mechanism 6 of the motor 31. In order to make the second conductive member 621 stably contact with the first conductive member 611, the second conductive member 621 includes but is not limited to an Ω-shaped conductive spring.
[0028] like Figures 1 to 4 The motor control module 7 is a conventional component of motor control. Those skilled in the art may refer to the prior art for implementation, and its specific structure will not be described in detail here.
[0029] Compared with the motor control module built into the moving part, the utility model sets the motor control module 7 outside the moving part 3, only the motor 31 and the gear set for transmission are built into the moving part 3, and the motor 31 is powered by the power supply rail 61, so there is no need to arrange external wires from the moving part 3, so as to avoid the problems of damage and entanglement of the external wires caused by the moving part 3 moving back and forth. The first conductive member 611 and the second conductive member 621 may be separated for a short time during the sliding contact process, resulting in a momentary disconnection of the electrical connection. The motor control module 7 needs to have a stable power supply and communication, and the momentary disconnection of the electrical connection is likely to cause abnormal operation. Therefore, setting the motor control module 7 outside the moving part 3 can also avoid abnormal operation of the motor control due to the momentary disconnection of the electrical connection between the first conductive member 611 and the second conductive member 621. Of course, the external placement of the motor control module 7 also reduces the weight of the moving part 3, reduces energy consumption, and saves space for the moving part 3.
[0030] like Figures 1 to 4 Both ends of the slide rail 2 are equipped with travel switches S for limiting the travel of the moving parts.
[0031] like Figures 1 to 4 Specifically, the two travel switches S are both rod-type limit switches, namely the first switch S1 and the second switch S2. The first switch S1, the second switch S2, the motor control module 7, the power supply rail 61 and the motor 31 are connected in series with each other, and the first switch S1 is connected in parallel with the first diode D1 in the forward direction, and the second switch S2 is connected in parallel with the second diode D2 in the reverse direction, thereby forming a control loop of the motor 31. The first switch S1 is mounted on the upper end of the rail 2, and the second switch S2 is mounted on the lower end of the rail 2.
[0032] like Figures 1 to 4 , the working principle of the motor control circuit is as follows:
[0033] The first switch S1 and the second switch S2 are normally closed switches.
[0034] (1) When the output terminal a of the motor control module 7 is positive and the output terminal b is negative, the current flows through the second switch S2, the second diode D2, and the first switch S1 to form a loop, and the moving part 3 moves upward.
[0035] When the moving part 3 moves upward and touches the first switch S1, the first switch S1 is disconnected, and the first diode D1 is turned off, the control loop is disconnected, and the moving part 3 stops moving. At this time, the moving part 3 reaches the upper limit.
[0036] (2) In the case of step (1), when the output terminal a of the motor control module 7 is negative and the output terminal b is positive, the current flows through the first diode D1 and the second switch S2 to form a loop, and the moving part 3 moves downward.
[0037] When the moving part 3 leaves the upper limit position, go to step 3.
[0038] (3) In the case of step (2), when the output terminal a of the motor control module 7 is negative and the output terminal b is positive, the current flows through the first switch S1 and the first diode D1 and the second switch S2 to form a loop, and the moving part 3 moves downward.
[0039] When the moving part moves downward and touches the second switch S2, the second switch S2 is disconnected, and the second diode D2 is turned off, the control loop is disconnected, and the moving part 3 stops moving. At this time, the moving part 3 reaches the lower limit.
[0040] (4) In the case of step (3), when the output terminal a of the motor control module 7 is positive and the output terminal b is negative, the current flows through the second diode D2 and the first switch S1 to form a loop, and the moving part 3 moves upward.
[0041] When the moving part 3 leaves the lower limit position, enter step (1).
[0042] like Figures 1 to 6In a specific embodiment, it further includes a mounting seat 8. The travel switch S is fixedly mounted on the mounting seat 8, and the mounting seat 8 is adjustably fixedly mounted on the slide rail 2 along the length direction of the slide rail 2.
[0043] like Figures 1 to 6 Specifically, the mounting seat 8 includes a cover 81, a return spring 82, a movable member 83 and a frame 84, and the frame 84 is slidably mounted on the outside of the slide rail 2. The frame 84 is provided with a mounting hole 842, and the movable member 83 is movably embedded in the mounting hole 842. The cover 81 is detachably buckled at one end of the mounting hole 842, and the movable member 83 is extended toward the other end of the mounting hole 842 to be provided with a limit block 832, and a return spring 82 is provided between the movable member 83 and the cover 81 to move the movable member 83. Under the action of the return spring 82, the limit block 832 is embedded in the tooth groove of the transmission rack 21, so that the mounting seat 8 is locked to the slide rail 2.
[0044] The movable member 83 is fixed with an operating portion 831 exposed outside the frame 84. The operating portion 831 is movably arranged inside the slide groove 843 of the frame 84, and the operating portion 831 includes but is not limited to a push plate. When in use, the movable member 83 is moved by the operating portion 831, so that the limit block 832 is disengaged from the tooth groove of the transmission rack 21; then, the mounting seat 8 is slid along the slide rail 2; when the mounting seat 8 reaches the target position, the operating portion 831 is released, so that the limit block 832 is embedded in another tooth groove of the transmission rack 21 under the action of the return spring 82, so that the mounting seat 8 is locked at the target position of the slide rail 2.
[0045] The frame 84 is provided with a mounting portion 844 for fixing and connecting the travel switch S. Preferably, the frame 84 is symmetrically provided with two mounting portions 844. When the travel switch S is mounted on one of the mounting portions 844 with the contact rod facing upward, the travel switch S is used as the second switch S2, which is the lower limit. When the travel switch S is mounted on the other mounting portion 844 with the contact rod facing downward, the travel switch S is used as the first switch S1, which is the upper limit. The mounting seat 8 is slidably adjusted and locked with the tooth groove spacing of the transmission rack 21 as a moving unit, which is convenient for positioning and installing the travel switch S, quantitatively adjusting the installation position of the travel switch S, thereby accurately adjusting the travel cutoff position of the moving component 3, and facilitating the debugging and setting of the travel of the moving component 3.
[0046] like Figures 1 to 7 The utility model also discloses a massage pad, including a cover assembly 100, wherein a massage device 200 is disposed inside the cover assembly 100. The massage device 200 can be removed and placed inside the cover assembly 100. The cover assembly 100 is a conventional component of an existing massage pad, including but not limited to being composed of wear-resistant cloth (or wear-resistant gauze), filler (such as sponge, latex, etc.) and artificial leather stitching. Those skilled in the art can refer to the existing massage pads for implementation, and no further description is given here.
[0047] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
