{MULTI-FUNCTIONAL MASSAGE DEVICE BASED ON MAGNETIC FIELD FOR VEHICLE SEAT AND VECHILE SEAT INCLUDING THE MASSAGE DEVICE}

The present invention relates to a multi-functional massage device for a vehicle seat based on a magnetic field and a vehicle seat having a multi-functional massage device based on a magnetic field, and more specifically, to a multi-functional massage device for a vehicle seat based on a magnetic field and a vehicle seat having a multi-functional massage device based on a magnetic field, which provides a massage function using a magnetic field and also has a cooling/heating function so that there is no need to configure a separate cooling/heating function device part in the vehicle seat, and is configured relatively compactly compared to a mechanical massage device so that it can be efficiently applied to a vehicle seat and also improve the degree of freedom in the design of the vehicle seat.

Massage is a medical auxiliary therapy that regulates the body's tone, helps blood circulation, and relieves fatigue by applying various forms of mechanical stimulation to parts of the body, such as kneading, pressing, pulling, tapping, or moving the body.

The increase in demand for massage has led to an increase in demand for massage devices or massage machines that provide artificial massage functions due to economic and time constraints. In other words, as the demand for relieving fatigue or stress by loosening tense muscles through massage increases, various massage devices that are time- and cost-effective are being released.

For example, a device is being developed that can provide massages to users by incorporating a module for providing massage into the seat of a vehicle, such as a car seat.

Fig. 1 is a perspective view showing a pneumatic vehicle massage chair according to the prior art. As shown, a plurality of air cells (3) are installed on a base plate (2) arranged inside a seat (1). A space is formed inside each of these air cells (3) so that air can be injected therein.

Since the air cells (3) of the vehicle massage chairs of the prior art are made of soft materials, their durability gradually weakens due to repeated contraction and expansion. In particular, when the massage chair is applied to the interior of a car, in seasons or regions where the outside temperature is high, the temperature inside the car becomes high, causing deformation of the air cells (3).

Accordingly, the soft air cell (3) exposed to the high temperature inside the car cannot come into contact with the uneven pad surface (not shown) when a passenger sits and is subjected to repeated loads, and slipping occurs in the pad surface portion that is relatively thin, and the slipped air cell (3) bends due to the applied load and is ultimately damaged, thereby preventing the massage system from achieving its original performance.

Meanwhile, in the case of a mechanical massage module including a roller or ball-shaped sample element proposed in Korean Patent Publication No. 10-2533638, there is a problem that it is relatively complex in configuration and large in volume, making it unsuitable for application to vehicle seats.

Therefore, there is a need for the development of a vehicle massage device that can be applied to vehicle seats and provide efficient massage.

The magnetic field-based multi-functional massage device according to the present invention is a massage device configured on a vehicle seat, and as shown in FIGS. 2 to 12, it largely includes a magnetic field generating unit (100), a heat dissipation unit (200), an electromagnetic wave absorption module (300), and a control unit (400), and may further include a magnetic field generating unit driving device (500).

Specifically, a magnetic field-based multi-functional massage device according to the present invention is a massage device configured on a vehicle seat, and as shown in FIGS. 2 to 12, includes: a device base plate (10) formed in an approximately rectangular shape; a magnetic field generating unit (100) provided on the device base plate (10) and configured to stimulate and massage a human body with the force of a magnetic field generated from a magnetic field generating coil provided inside; a heat dissipation unit (200) provided on the magnetic field generating unit (100) and configured to dissipate heat generated from the magnetic field generating unit (100); an electromagnetic wave absorption module (300) provided on the magnetic field generating unit (100) and configured to absorb electromagnetic waves generated from the magnetic field generating unit (100); and a control unit (400) that controls turning the device on/off, operations of the magnetic field generating unit (100) and the heat dissipation unit (200), and operations of the driving device unit (400). In addition, the magnetic field-based massage field for a vehicle seat of the present invention further includes a magnetic field generating unit driving device (500) that drives the magnetic field generating unit (100) up and down the seat.

The above magnetic field generating unit (100) includes a magnetic field coil receiving housing (110) in the shape of a body, a magnetic field generating coil (120) provided inside the magnetic field coil receiving housing (110) to generate a magnetic field, and a circuit control module (130) provided on one side of the magnetic field generating coil (120) to control the magnetic field generating coil (120) according to an input command input through the control unit (400).

The above magnetic field generating coil (120) is fixed at a predetermined distance from the lower surface of the magnetic field coil receiving housing (110) through a fixed bracket (121), that is, in a state where there is a separation space.

The magnetic field generating coil (120) above generates a large amount of heat energy by repeatedly or intermittently flowing a pulse current of a considerable size through the magnetic field generating coil (120), and the heat is dissipated by the operation of the heat dissipation structure and the heat dissipation unit (200) configured in the magnetic field coil receiving housing (110).

Meanwhile, in the case where the present invention further includes a magnetic field generating unit driving device (500) to be described below, the magnetic field coil receiving housing (110) of the magnetic field generating unit (100) is further provided with a component connected to the magnetic field generating unit driving device (500), which will be described in detail below.

Next, the heat dissipation unit (200) is provided in the magnetic field generating unit (100) and is a component configured to dissipate heat generated from the magnetic field generating unit (100).

Specifically, the heat dissipation unit (200) includes a plate through-hole (210) formed in the device base plate (10), a housing through-hole (220) formed in the lower surface of the magnetic field coil receiving housing (110), a heat dissipation hole (230) formed in the upper surface and side surfaces of the magnetic field coil receiving housing (110), and a heat dissipation fan (240) provided while closing the housing through-hole (220) of the magnetic field coil receiving housing (110) or mounted on the lower surface of the housing through-hole (220).

The heat dissipation holes formed on the upper surface of the magnetic field coil receiving housing (110) in the above heat dissipation hole (230) are formed in multiple numbers at radial intervals from the center of the upper surface, and the heat dissipation holes formed on the side of the magnetic field coil receiving housing (110) can be formed as holes opened in a polygonal shape such as a square or a circle.

The hot air radiated by the above-mentioned heat dissipation unit (200) can provide a function of providing hot air in winter, etc., separately from or in place of the heating function by the heating wire provided on the vehicle seat. In addition, the heat dissipation unit (200) in the present invention can further include a fan-integrated thermoelectric module (250) that generates cold air (heat absorption) on one side and generates warm air (heat generation) on the other side by the Peltier effect on the lower side of the heat dissipation fan (240). In this case, regardless of whether the massage function is used, a cooling function (cold air seat function) and a heating function (heated seat function) can be provided depending on the direction of the current.

The heat dissipation unit (200) including the above-described fan-integrated thermoelectric generator module dissipates heat caused by the generation of a magnetic field during a massage mode in which a magnetic field is generated to provide a massage. The warm air dissipated at this time can provide a heating function to the vehicle seat. At this time, the operation of the thermoelectric generator module (250) is stopped.

In addition, when it is desired to provide a cooling function to the vehicle seat, such as in the summer, the thermoelectric element module (250) is operated so that cold air (cold wind) from the inside is blown by the heat dissipation fan (240). At this time, the operation of the thermoelectric element module (250) can provide cold wind while cooling the heat generated by the magnetic field in the massage mode, and when the massage mode is not used (i.e., when the operation of the magnetic field generating unit (100) is not operated), only cold wind is blown, thereby providing a cooling function to the vehicle seat.

Of course, when the massage mode is not used, that is, the operation of the thermoelectric element module (250) is not performed, and only the heat dissipation fan (240) is operated so that the ventilation function by the heat dissipation fan (240) is provided.

In the present invention, the operation of the thermoelectric element module (250) can be automatically operated based on a detection signal of a temperature sensor (not shown) provided on one side of the vehicle seat. In other words, when the temperature is higher than the set temperature due to the heat generated by the magnetic field in the magnetic field generating unit (100), the temperature sensor can detect this and cause the thermoelectric element module (250) to operate.

Next, the electromagnetic wave absorption module (300) is a component configured to absorb electromagnetic waves generated from the magnetic field generation unit (100) by being provided on one side of the device base plate (10) and/or one side of the magnetic field generation unit (100). The electromagnetic wave absorption module (300) may be configured as a permanent magnet module provided on one side of the device base plate (10).

The above electromagnetic wave absorption module (300) is provided on one side of the upper surface of the base plate (210) and includes a magnet receiving housing (310) with both ends opened outward, and a permanent magnet (320) provided within the magnet receiving housing (310).

The above permanent magnet (320) may be composed of a cylindrical permanent magnet that penetrates along the central axis.

These electromagnetic wave absorbing modules (300) can function as absorbers that absorb electromagnetic waves.

Next, the control unit (400) is a component that controls the on/off of the device, the operation of the magnetic field generating unit (100) and the heat dissipation unit (200), and the operation of the driving device unit (400).

Specifically, the control unit (400) includes a device on/off switch unit (410), a magnetic field control unit (420) for controlling the magnetic field intensity and generation cycle generated from the magnetic field generating unit (100), and a heat dissipation control unit (430) for controlling the operation of the heat dissipation fan (240) of the heat dissipation unit (200).

And the above control unit (400) further includes a control unit for controlling the operation of other component(s) described below, which is described below.

The above-mentioned control unit (400) may be provided on one of the dashboard, steering wheel, and seat of the vehicle, or may be configured as an integral part with a control module of the vehicle provided on the dashboard, steering wheel, or seat.

Meanwhile, in the above description, the magnetic field generating unit (100) is configured to be fixed to the vehicle seat, but may be configured to be driven up and down. To this end, the magnetic field-based multi-functional massage device according to the present invention may further include a magnetic field generating unit driving device (500) that allows the magnetic field generating unit (100) to be driven up and down inside the seat.

The magnetic field generating unit driving device (500) includes a driving rail (510) provided on the inner side of a vehicle seat, a driving guide plate (520) provided on the back (inner side) of the vehicle seat, a driving driving unit (530) provided on one side of the device base plate (10) and configured to generate a driving force to move along the driving rail (510), a driven driving unit (540) provided on the other side of the device base plate (10) and configured to drive along the driving rail (510) by the driving force of the driving driving unit (530), and a plurality of rolling rollers (550) formed on the upper surface of the magnetic field coil receiving housing (110) of the magnetic field generating unit (100) and rollingly rotating while coming into contact with the driving guide plate (520).

The above rack gear (512) is provided on the inner side of the lower surface of the guide frame (511) and meshes with the driving gear (535) of the driving driving unit (530) to be described below. At this time, the rack gear (512) is formed on the edge side of an extension plate that extends from the inner side of the guide frame (511) with a predetermined width. In other words, the extension plate extends with a predetermined width, and is formed as a flat portion on the proximal end portion side based on the width direction, and as a rack gear portion on the distal end portion side.

In addition, a limit switch (513) is provided at one end and the other end of the driving rail (510), and when the projection formed on the device base plate (10) comes into contact with the projection at the point where movement toward the upper or lower side is completed, further movement can be restricted.

Here, the driving guide plate (520) may be formed with an opening (521) in the center so that the magnetic field generated from the magnetic field generating unit (100) can be smoothly transmitted to the front side (human body side).

In addition, the driving guide plate (520) may be formed with a driving guide slot (roller guide slot) (522) formed through which the back of the seat is exposed so that the cloud roller (550), which will be described in detail below, can be guided and physically massage the back of the human body. This will be described in detail in the description of the cloud roller (550) below.

The above support bracket (532) is provided with a bearing, and the driving shaft (533) is rotatably supported by the shaft bearing.

The above driving force transmission means may be composed of a gear train or a gear module. For example, the driving force transmission means may be composed of a first gear provided at an end of a rotation shaft of the driving motor (531), and a second gear provided on the driving shaft (533) and meshed with the first gear.

Continuing, the driven driving unit (540) is provided on the other side of the device base plate (10) and is a component configured to drive along the driving rail (510) by the driving force of the driving driving unit (530).

Specifically, the driven driving unit (540) includes a plurality of roller support brackets (541) provided with a gap on both sides of the upper surface of the other end of the device base plate (10), and a driven roller member (543) having a rotational shaft (542) rotatably coupled to the roller support brackets (541) and guided (i.e., driven) along a guide frame (511) of a driving rail (510).

In addition, the driven driving unit (540) further includes a stopper (544) that is provided on one or both sides of the lower surface of the device base plate (10) and comes into contact with a stopper projection (not shown) provided on both ends (both ends in the driving direction) of the guide frame (511) of the driving rail (510) to limit the driving of the driven driving unit (540). In the drawing, the stopper (544) is shown as being provided on one side of the device base plate (10), but may be provided on both sides of the device base plate (10). As mentioned above, if the limit switch (513) is provided, the stopper (544) may be omitted.

Continuing, the plurality of cloud rollers (550) are formed on the upper surface of the magnetic field coil receiving housing (110) of the magnetic field generating unit (100) and are components that rotate in a cloud manner while contacting the driving guide plate (520).

The present invention can be configured to physically pressurize and massage the back of a passenger in contact with a vehicle seat by the plurality of cloud rollers (550).

In other words, as shown in FIGS. 10 and 11, the plurality of cloud rollers (550) may be configured such that the edge portions contact the driving guide plate (520) to roll, and the central portions are exposed to the back side of the sheet through the driving guide slot (522) formed in the driving guide plate (520) to apply pressure.

Specifically, the cloud roller (550) is formed in a cylindrical shape and includes a roller portion (551) that rotates in a cloud by contacting the back surface of a driving guide plate (520) in which the driving guide slot (522) is formed at an edge portion in the circumferential center of the roller portion (551) and contacting the back surface of the front surface of the seat through a driving guide slot (522) formed in the longitudinal direction of the driving guide plate (520) to a predetermined length (movement distance).

The above massage protrusion (552) may be formed by protruding across the entire circumferential surface of the roller portion (551), or may be formed with protrusions having the same degree of protrusion and/or different degrees of protrusion at intervals in the circumferential direction, and may also be formed in a tooth shape.

As described above, since the magnetic coil receiving housing (110) is provided with a cloud roller (550) on the upper surface, it can drive smoothly while contacting the back surface of the driving guide plate (520), and can perform a magnetic field massage while being as close as possible to the human body when moving up and down.

In addition, when the cloud roller (550) is configured with a massage protrusion (552), the massage protrusion (552) not only provides a massage function, but also moves while being guided along the driving guide slot (522), thereby ensuring stable driving performance of the device.

Meanwhile, the magnetic field generation drive device (500) may further include an elastic support unit (560) provided between the device base plate (10) and the magnetic field generation unit (100) to elastically support the magnetic field generation unit (100) so as to freely move up and down relative to the device base plate (10).
