Description

Massage device and massage pad TECHNICAL FIELD

[0001] The utility model relates to massage mechanism field, specifically to a massage device and massage pad. BACKGROUND

[0002] The existing massage pad usually includes a skeleton, an outer cover assembly and a massage device. The massage device further includes a sliding rail and a moving component (also called a massage movement core). The moving component is slidably arranged on the sliding rail. The moving component is provided with a motor control module, a motor and a massage assembly. The moving component is driven by the motor to move back and forth along the sliding rail, and the massage assembly is driven to move. The existing back massage device of the massage pad has the following problems: since the motor control module is arranged inside the moving component, it needs to be electrically connected to the motor control module through a wire, and the motor control module and a human-computer interaction module (such as a key module or a touch screen module) are communicatively connected. The back and forth movement of the moving component can easily cause the wire to be damaged, entangled or even disconnected, affecting the normal use of the back massage device. In addition, the motor control module is arranged inside the moving component, which not only occupies space but also increases the total weight of the moving component, increases energy consumption and brings many inconveniences to the maintenance of the motor control module.

[0003] In addition, in order to limit the stroke of the moving component, a Hall sensor is usually arranged inside the moving component, and a magnet is arranged at both ends of the sliding rail to cooperate with the Hall sensor. However, the Hall sensor has a high cost and is easily disturbed by temperature, magnetic field and other factors, and needs additional calibration and debugging, which brings many inconveniences to the production and assembly of the back massage device and subsequent maintenance.

[0013] Compared with the prior art, the massage device has the following advantages:

[0014] Firstly, compared with the motor control module being built-in the moving component, the motor control module is arranged outside the moving component in the massage device, only the motor and the gear set used for transmission are built-in the moving component, and the motor is powered through the first conductive part and the second conductive part, without arranging a wire. In addition, the first conductive part and the second conductive part may be separated for a short time in the process of sliding contact, so that the electric connection is instantaneously disconnected. The motor control module needs stable power supply and communication, and the instant disconnection of the electric connection easily leads to abnormal work. Arranging the motor control module outside the moving component can avoid the abnormal work of the motor control caused by the instant disconnection of the electric connection.

[0024] The specific embodiments of the utility model will be described below with reference to the drawings. In order to fully understand the utility model, many details are described below, but the utility model can be implemented without these details for those skilled in the art.

[0025] As shown in Figs. 1 to 4, the utility model discloses a massage device, which comprises slide rails 2, a moving part 3 and a massage part 4. The upper ends of the two slide rails 2 are fixedly connected to the same upper cross beam 1, and the lower ends are fixedly connected to the same lower cross beam 5, so that the two slide rails 2 are arranged in parallel with each other. The moving part 3 is assembled with the massage part 4. The moving part 3 is slidably arranged on the two slide rails 2 respectively. One side of the slide rail 2 is provided with a transmission rack 21. The moving part 3 is internally assembled with a motor 31, and the output shaft of the motor 31 is transmissionally connected to the transmission rack 21 through a gear set, for sliding the moving part 3 along the slide rail 2. Of course, the motor 31 is also used for driving the massage part 4.

[0026] As shown in FIG. 1 to FIG. 4, the massage device further comprises a power supply slide rail 61 and a motor control module 7. The power supply slide rail 61 is fixed with a plurality of first conductive members 611. The moving component 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 component 3, one side of the moving component 3 is slidably arranged on the power supply slide rail 61, and the second conductive members 621 are slidably abutted on the first conductive members 611, so that the motor control module 7 is electrically connected to the motor 31.

[0027] More specifically, one side of the outer shell of the power supply slide rail 61 is provided with a sliding sleeve 62, the power supply slide rail 61 is slidably arranged in the sliding sleeve 62, and one end surface of the power supply slide rail 61 is fixed with two long strip-shaped first conductive members 611. The sliding sleeve 62 is fixed with two second conductive members 621 on the opposite side of the first conductive members 611, and the second conductive members 621 are electrically connected to the motor 31 through the built-in wires (not shown in the figure) of the moving component 3. The two second conductive members 621 correspond to the two first conductive members 611 respectively and are slidably abutted thereon. The power supply slide rail 61, the first conductive members 611, the second conductive members 621 and the sliding sleeve 62 form a power taking mechanism 6 of the motor 31. In order to make the second conductive members 621 and the first conductive members 611 in stable contact, the second conductive members 621 include but are not limited to Ω-shaped conductive springs.

[0028] As shown in FIG. 1 to FIG. 4, the motor control module 7 belongs to the conventional component of motor control, and those skilled in the art can refer to the prior art for implementation, and the specific structure is not described here.

[0029] Compared with the built-in motor control module in the moving component, the motor control module 7 is arranged outside the moving component 3, only the motor 31 and the gear set for transmission are built in the moving component 3, and the motor 31 is powered through the power supply slide rail 61, without external wires arranged from the moving component 3, avoiding the problems of damage and entanglement of external wires caused by back and forth movement of the moving component 3. The first conductive members 611 and the second conductive members 621 may be separated for a short time during sliding contact, resulting in instantaneous disconnection of electrical connection. The motor control module 7 needs stable power supply and communication, and instantaneous disconnection of electrical connection easily leads to abnormal work. Therefore, arranging the motor control module 7 outside the moving component 3 can also avoid abnormal work of the motor control caused by instantaneous disconnection of electrical connection of the first conductive members 611 and the second conductive members 621. Of course, the external motor control module 7 also reduces the weight of the moving component 3, reduces energy consumption, and saves the space of the moving component 3.

[0030] As shown in FIG. 1 to FIG. 4, both ends of the slide rail 2 are equipped with stroke switches S for limiting the stroke of the moving component.

[0031] As shown in FIG. 1 to FIG. 4, specifically, two travel switches S are both touch rod limit switches, which are respectively a first switch S1 and a second switch S2. The first switch S1, the second switch S2, the motor control module 7, the power supply slide rail 61 and the motor 31 are connected in series with each other, and the first switch S1 is connected in parallel with a first diode D1 in positive direction, and the second switch S2 is connected in parallel with a second diode D2 in reverse direction, thereby forming a control loop of the motor 31. Wherein, the first switch S1 is assembled at the upper end of the slide rail 2, and the second switch S2 is assembled at the lower end of the slide rail 2.

[0032] As shown in FIG. 1 to FIG. 4, the working principle of the control loop of the motor is as follows:

[0033] The first switch S1 and the second switch S2 are normally closed switches.

[0034] (1) When the output end a of the motor control module 7 is positive and the output end b is negative, the current flows through the second switch S2 and the second diode D2, the first switch S1 to form a loop, and the moving part 3 moves upward.

[0035] When the moving part 3 touches the first switch S1 and moves upward, the first switch S1 is disconnected, the first diode D1 is cut off, the control loop is disconnected, and the moving part 3 stops moving. At this time, the moving part 3 reaches the upper limit position.

[0036] (2) In the case of step (1), when the output end a of the motor control module 7 is negative and the output end 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, step 3 is entered.

[0038] (3) In the case of step (2), when the output end a of the motor control module 7 is negative and the output end 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 3 touches the second switch S2 and moves downward, the second switch S2 is disconnected, the second diode D2 is cut off, the control loop is disconnected, and the moving part 3 stops moving. At this time, the moving part 3 reaches the lower limit position.

[0040] (4) In the case of step (3), when the output end a of the motor control module 7 is positive and the output end 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, step (1) is entered.

The operation part 831 is movably arranged inside a sliding groove 843 of the frame 84, and the operation part 831 includes but is not limited to a push plate. In use, the movable piece 83 is moved through the operation part 831, so that the limiting block 832 is separated from the tooth groove of the transmission rack 21; then, the mounting base 8 is slid along the slide rail 2; when the mounting base 8 reaches the target position, the operation part 831 is loosened, so that the limiting block 832 is embedded in another tooth groove of the transmission rack 21 under the action of the reset spring 82, so that the mounting base 8 is locked on the target position of the slide rail 2.

[0045] The frame 84 is provided with a mounting part 844 for fixedly connecting the travel switch S. Preferably, the frame 84 is symmetrically provided with two mounting parts 844. When the travel switch S is arranged on one of the mounting parts 844 with the contact rod upward, the travel switch S is used as the second switch S2 for the lower limit. When the travel switch S is arranged on the other mounting part 844 with the contact rod downward, the travel switch S is used as the first switch S1 for the upper limit. The mounting base 8 is slidably adjusted and locked with the tooth groove spacing of the transmission rack 21 as one moving unit, which is convenient for positioning and installing the travel switch S, quantitatively adjusting the installation position of the travel switch S, and thus accurately adjusting the travel cut-off position of the moving part 3, and facilitating the debugging and setting of the travel of the moving part 3.
