Description

Technical Field

[0001] This utility model relates to the field of seat massage technology, and in particular to a seat and a hammer massage structure for the seat. Background Technology

[0002] Currently, most massage chairs are equipped with pneumatic massage systems. However, these systems suffer from slow airbag inflation / deflation frequencies (typically 3 seconds per cycle) and weak massage sensations. A novel massage structure is needed to enhance massage frequency and intensity, thereby improving the passenger's massage experience. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a seat and a hammer massage structure for the seat, which can significantly increase the massage frequency and intensity, resulting in a more comfortable car seat massage experience.

[0004] This utility model is achieved through the following solution: a hammer massage structure for a seat, comprising:

[0005] Support base;

[0006] A massage hammer includes a swing arm and a hammer head for striking, wherein a first end of the swing arm is rotatably mounted on a support about a first axis to swing relative to the support between a first swing position and a second swing position; and a second end of the swing arm is connected to the hammer head.

[0007] An elastic element, connected between the support base and the swing arm, is used to drive the swing arm to swing from the second swing position to the first swing position so that the hammer head can strike.

[0008] A drive mechanism is used to periodically drive the swing arm from the first swing position to the second swing position in conjunction with the elastic element, so as to store energy in the elastic element; wherein,

[0009] The elastic element is configured such that the swing speed of the pendulum from the second swing position to the first swing position is greater than the swing speed from the first swing position to the second swing position.

[0010] A further improvement of this utility model is that the driving mechanism includes a driving wheel and a driven wheel, and the driving wheel and the driven wheel satisfy the following: the rotation of the driving wheel drives the driven wheel to rotate, which in turn drives the swing arm to swing from the first swing position to the second swing position; when the swing arm swings from the second swing position to the first swing position, it drives the driven wheel to accelerate its rotation so as to disengage from the driving wheel.

[0011] A further improvement of this utility model is that the driving wheel is provided with a first stop and the driven wheel is provided with a second stop. When the first stop rotates with the driving wheel, it can contact and push against the second stop, thereby driving the driven wheel to rotate.

[0012] A further improvement of this utility model is that the first stop is configured to extend radially from the circumferential surface of the driving wheel, and the second stop is configured to extend axially from the end face of the driven wheel.

[0013] A further improvement of this invention is that both the driving wheel and the driven wheel can rotate around the second axis.

[0014] A further improvement of this utility model is that the passive wheel is provided with a pushing part, which can contact and push the swing arm when the passive wheel rotates, so that the swing arm can swing from the first swing position to the second swing position.

[0015] A further improvement of this utility model is that the drive mechanism further includes a motor and a reduction mechanism that is connected between the motor and the drive wheel to generate low-speed, high-torque output.

[0016] A further improvement of this utility model is that the reduction mechanism includes a first bevel gear and a second bevel gear meshing with the first bevel gear, the first bevel gear being fixedly connected to the motor, and the second bevel gear being fixedly connected to the drive wheel.

[0017] A further improvement of this utility model is that the driving mechanism further includes a second shaft extending along the second axis, one end of the second shaft being fixedly connected to the driving wheel and rotatably connected to the driven wheel, and the other end being fixedly connected to the second bevel gear.

[0018] A further improvement of this utility model is that the first end of the swing arm is rotatably connected to the support base via a first shaft extending along the first axis, the elastic element is a torsion spring, the elastic element is sleeved on the first shaft, and the two ends of the elastic element are respectively secured to the swing arm and the support base.

[0019] A further improvement of this utility model is that the elastic element is a compression spring, one end of the elastic element is fixed to the support base, and the other end of the elastic element is fixed to the swing rod.

[0020] This utility model also provides a seat, wherein at least one hammering massage structure as described above is installed on the seat cushion or backrest.

[0021] This utility model includes, but is not limited to, the following beneficial effects:

[0022] It adopts a mechanical hammer massage method, and through a drive mechanism and elastic element combined, the drive mechanism provides drive and stores energy in the elastic element when the swing arm moves from the first swing position to the second swing position, and the elastic element releases energy to provide drive when the swing arm moves from the second swing position to the first swing position. By combining the two drive methods, it can better adapt to the needs of different hammering frequencies and hammering intensities. Moreover, because the energy release of the elastic element can generate faster acceleration, the hammer head can hammer quickly, which can significantly increase the massage intensity of the massage hammer and bring a more comfortable seat massage experience to the occupant.

[0023] By using an overrunning clutch consisting of a drive wheel and a driven wheel to drive the massage hammer in conjunction with the elastic element, the motor can work continuously. During the continuous operation of the motor, the energy storage and release of the elastic element alternate, which can achieve a periodic and strong automatic hammering massage effect.

[0024] By connecting a reduction mechanism between the motor and the drive wheel, the speed of the motor output is reduced and the output torque is increased, resulting in a smoother output with sufficient torque to drive the massage hammer. At the same time, the hammering force and frequency of the massage hammer can be controlled more flexibly.

[0025] By distributing multiple massage hammers, massage can be applied to different areas, further enhancing massage comfort. In addition, different massage hammers can be driven by the same motor to reduce the space occupied by the hammer massage structure and save costs, or different motors can be used to drive them separately to achieve more precise and flexible distributed massage and improve the massage effect.

Detailed Implementation

[0048] To address the problems of slow airbag expansion and contraction frequency and weak massage sensation in existing pneumatic massage systems, this invention provides a seat and a hammer massage structure for the seat, which can significantly increase the massage frequency and intensity, resulting in a more comfortable car seat massage experience. The following detailed description, in conjunction with the accompanying drawings, further illustrates the seat and the hammer massage structure for the seat.

[0049] See Figure 1 , Figures 6-8 as well as Figures 10-18 As shown, a hammer massage structure for a seat includes: a support base 1, a massage hammer 2, an elastic element 3, and a drive mechanism. The massage hammer 2 includes a swing arm 21 and a hammer head 22 for hammering. The first end of the swing arm 21 is rotatably mounted on the support base 1 about a first axis L1, so as to be in a first swing position relative to the support base 1 (e.g., ...). Figure 6 (as shown) and the second swing position (as shown) Figure 7The swing arm 21 oscillates between the support base 1 and the hammer head 22. The second end of the swing arm 21 extends from the support base 1 and connects to the hammer head 22. An elastic element 3 connects the support base 1 and the swing arm 21, driving the swing arm 21 to swing from the second swing position to the first swing position, so that the hammer head 22 can perform hammering. A driving mechanism drives the swing arm 21 to swing from the first swing position to the second swing position. Specifically, the elastic element 3 is in an energy-storing state during the swing of the swing arm 21 from the first swing position to the second swing position and in an energy-releasing state during the swing of the swing arm 21 from the second swing position to the first swing position. The driving mechanism cooperates with the elastic element 3 to periodically drive the swing arm 21 from the first swing position to the second swing position to store energy in the elastic element 3, thereby achieving a periodic hammering massage effect. It should be noted that the elastic element 3 is configured such that the swing speed of the swing arm 21 from the second swing position to the first swing position is greater than the swing speed from the first swing position to the second swing position. Specifically, this can be achieved by adjusting the drive parameters of the motor 41 and the elastic coefficient of the elastic element 3. By limiting the relationship between the swing speeds, the drive mechanism can operate continuously. During this continuous operation, drive is provided only when the swing arm 21 moves from the first swing position to the second swing position, storing energy in the elastic element 3. When the swing arm 21 moves from the second swing position to the first swing position, the energy release from the elastic element 3 provides the drive. This alternating energy storage and release of the elastic element 3 achieves an automatic, periodic hammering massage effect without frequent start-stop of the drive mechanism. Furthermore, by generating a faster acceleration from the energy release of the elastic element 3, the massage hammer 2 can strike rapidly, thereby increasing the hammering force of the massage hammer 2. This hammering force is determined by the elastic coefficient and stored energy of the elastic element 3, and can be adjusted by changing the parameters of the elastic element 3. Additionally, the time interval between two consecutive hammering strikes is determined by the sum of the two swing speeds. Therefore, the hammering frequency can be achieved by adjusting either the drive parameters of the drive mechanism or the elastic coefficient of the elastic element 3, offering greater flexibility in adjustment. A higher hammer frequency and greater hammer force can bring a more comfortable seat massage experience to the occupants.

[0050] The core principle of this hammer-massage structure is that the elastic potential energy of the elastic element 3 is converted into kinetic energy, enabling the massage hammer 2 to strike rapidly. The storage and rapid release of this elastic potential energy can be achieved using various types of elastic elements 3, such as torsion springs and compression springs. Simultaneously, at the end of the massage or when the body leans against the hammer head 22, the hammer head 22 can move backward due to the elastic action of the elastic element 3, ensuring both comfort and safety while riding.

[0051] The number of massage hammers 2 can be one, or two or more as needed, as described below with different embodiments:

[0052] First embodiment, participating Figures 1-9 As shown: This embodiment is a one-to-one motor driven type. Specifically, there is one massage hammer 2. The drive mechanism includes a motor 41 and an overrunning clutch 42. The overrunning clutch 42 includes a driving wheel 421 and a driven wheel 422. The driving wheel 421 and the driven wheel 422 satisfy the following conditions: the rotation of the driving wheel 421 drives the driven wheel 422 to rotate, which in turn drives the swing arm 21 to swing from a first swing position to a second swing position; when the swing arm 21 swings from the second swing position to the first swing position, it drives the driven wheel 422 to accelerate and rotate to disengage from the driving wheel 421. Both the driving wheel 421 and the driven wheel 422 can rotate around a second axis L2, and they can rotate relative to each other. The driving wheel 421 is provided with a first stop 423, and the driven wheel 422 is provided with a second stop 424. When the first stop 423 rotates with the driving wheel 421, it can contact and push against the second stop 424, thereby driving the driven wheel 422 to rotate. Specifically, the first stop 423 is configured to extend radially from the circumferential surface of the driving wheel 421, and the second stop 424 is configured to extend axially from the end face of the driven wheel 422. The second stop 424 is located in front of the rotation path of the driving wheel 421, so that when the first stop 423 rotates with the driving wheel 421, it can contact and push against the second stop 424 to drive the driven wheel 422 to rotate. When the driven wheel 422 accelerates, the second stop 424 disengages from the first stop 423, thereby causing the driven wheel 422 to disengage from the driving wheel 421. Figure 6 and Figure 8 As shown. The first stop 423 can also be configured to extend axially from the end face of the driving wheel 421, and the end face of the driven wheel 422 is provided with an arc-shaped groove extending along the rotation path of the first stop 423. The first stop 423 is inserted into the arc-shaped groove, and the second stop 424 is the front end face of the arc-shaped groove. When the first stop 423 rotates with the driving wheel 421, it contacts and pushes against the second stop 424. When the driven wheel 422 rotates relative to the driving wheel 421, the first stop 423 disengages from the second stop 424 and slides along the arc-shaped groove. The passive wheel 422 is provided with a pushing part 425. When the passive wheel 422 rotates, the pushing part 425 can contact and push the swing rod 21 so that the swing rod 21 can swing from the first swing position to the second swing position. The positions of the second axis L2 and the pushing part 425 should satisfy the following: the vertical distance from the second axis L2 to the swing rod 21 is kept not greater than the vertical distance from the pushing part 425 to the second axis L2.

[0053] The support base 1 can support the swing arm 21 to a certain height, providing a larger swing space for the swing arm 21. Specifically, in some embodiments, the support base 1 includes a support plate and a bracket 11 fixed on the support plate corresponding to the position of the swing arm 21. The first end of the swing arm 21 is rotatably connected to the bracket 11 via a first shaft 25 extending along the first axis L1. Specifically, the bracket 11 is U-shaped, and a pair of flange plates of the bracket 11 have opposing shaft holes. The first shaft 25 passes through the pair of shaft holes, and the first end of the swing arm 21 is fixed with a pair of connecting ears 24. The pair of connecting ears 24 are connected to the two ends of the first shaft 25 on the outside of the shaft holes at different locations. The elastic element 3 is a torsion spring, which is sleeved on the first shaft 25 and located between the pair of flange plates. The two ends of the elastic element 3 are respectively secured to the swing arm 21 and either of the flange plates.

[0054] The drive mechanism also includes a motor 41, which provides power to the rotation of the drive wheel 421. However, since the motor 41 typically operates at a high speed, to control the force and frequency of the hammering, the drive mechanism also includes a reduction mechanism 43, which is connected between the motor 41 and the drive wheel 421 to generate a low-speed, high-torque output. The reduction mechanism 43 can have different structural forms, such as a planetary gear combination, a worm gear combination, or a combination of bevel teeth. In this embodiment, as shown... Figures 1-5 As shown, the reduction mechanism 43 is a structure in which the first bevel gear 431 and the second bevel gear 432 mesh. The drive mechanism also includes a second shaft 44 extending along the second axis L2. In this embodiment, the motor 41, the overrunning clutch 42 and the second shaft 44 are all located on one side of the rocker arm 21. One end of the second shaft 44 is fixedly connected to the driving wheel 421 and rotatably connected to the driven wheel 422. Both the driving wheel 421 and the driven wheel 422 have shaft holes. After the second shaft 44 passes through the two shaft holes, it is locked on the outside of the driven wheel 422 by a self-tapping screw 45. Specifically, the protruding end of the second shaft 44 has a hole for the self-tapping screw 45 to be inserted and locked. A rolling bearing is nested in the shaft hole on the driven wheel 422. The relative rotation between the driven wheel 422 and the second shaft 44 is realized by the rolling bearing. Preferably, the rotational connection between the driven wheel 422 and the second shaft 44 can also be achieved by using an inner ring 426 and a ball bearing 427, as shown in the following example. Figure 4 and Figure 5As shown, the driven wheel 422 has an inner ring 426 inside its shaft hole, and a ring of ball bearings 427 is provided between the inner ring 426 and the driven wheel 422. The ball bearings 427 can be supported and limited by an annular retainer. The inner ring 426 is fixed relative to the second shaft 44 after assembly, so that the two can rotate synchronously. By adding ball bearings 427 between the driven wheel 422 and the inner ring 426, the sliding friction between the inner ring 426 and the driven wheel 422 is changed to rolling friction, reducing friction and abnormal noise. The first bevel gear 431 is fixed to the motor 41, and the second bevel gear 432 is fixedly connected to the other end of the second shaft 44. In this embodiment, by connecting a reduction mechanism 43 between the motor 41 and the driving wheel 421, the reduction mechanism 43 reduces the output speed of the motor 41 and increases the output torque, making the output smoother and providing sufficient torque to drive the massage hammer 2. At the same time, it allows for more flexible control of the hammering force and frequency of the massage hammer 2.

[0055] The first stop 423 is an extension handle formed on the driving wheel 421, extending radially out of the driving wheel 421. A similar extension handle is also formed on the driven wheel 422. The pushing part 425 is vertically fixed to the end of the extension handle and extends towards the projection position of the rocker arm 21. To reduce the friction between the pushing part 425 and the rocker arm 21 during the pushing process, the pushing part 425 is preferably a cylinder with a smooth surface. The second stop 424 is a stop point fixed on the extension handle. In the installed state, the driven wheel 422 is adjacent to the driving wheel 421, and the second stop 424 is located along the rotation path of the first stop 423. Figure 6 The arrow in the image points to the front side of the first stop 423 as the drive wheel 421 rotates.

[0056] In this embodiment, an overrunning clutch 42, consisting of a driving wheel 421 and a driven wheel 422, is used in conjunction with the elastic element 3 to drive the massage hammer 2. This allows the motor 41 to operate continuously. During continuous operation, the motor 41 only provides driving force when the swing arm 21 moves from the first swing position to the second swing position. The driving force when the swing arm 21 moves from the second swing position to the first swing position is entirely provided by the elastic element 3. This alternating energy storage and release of the elastic element 3 achieves an automatic, periodic hammering massage effect without frequent starting and stopping of the motor 41. The specific hammering motion is achieved through two stages of the elastic element 3: an energy storage stage and an energy release stage. See details... Figure 1 , Figures 6-8 As shown:

[0057] From the first swing position (e.g.) Figure 6 (As shown) Swing to the second swing position (e.g.) Figure 7The process shown is the energy storage stage of the elastic element 3: the driving wheel 421 rotates counterclockwise under the drive of the motor 41 (i.e., in the direction of the arrow). When the edge of the first stop 423 contacts the second stop 424, the driving wheel 421 and the driven wheel 422 engage, that is, the overrunning clutch 42 is engaged. The driving wheel 421 transmits the rotational force to the driven wheel 422 through the first stop 423 and the second stop 424. At this time, the driven wheel 422 begins to rotate, driving the rocker arm 21 to rotate clockwise, thereby causing the elastic element 3 connected to the rocker arm 21 to begin storing elastic potential energy (for a torsion spring, energy is stored by torsion).

[0058] From the second swing position (e.g.) Figure 7 (As shown) Swing to the first swing position (e.g.) Figure 8 The process shown is the energy release stage of the elastic element 3: when the driving wheel 421 rotates to a certain angle (i.e., the pushing part 425 is perpendicular to the swing rod 21, corresponding to the swing rod 21 swinging to...), the process is the energy release stage of the elastic element 3. Figure 7 When the second swing position is reached, the first stop 423 is about to disengage from the second stop 424, which is the critical state of the overrunning clutch 42. Because the driven wheel 422 is connected by a rolling bearing and the second shaft 44, the rotation of the driving wheel 421 will not generate torque on the driven wheel 422. Before the critical state, the rotation of the driven wheel 422 is driven by the contact between the second stop 424 on it and the first stop 423 on the driving wheel 421. As the driving wheel 421 rotates, the rocker arm 21 swings, causing the elastic element 3 to deform and store energy. Under the action of the elastic element 3 When the swing arm 21 exerts a downward force on the driven wheel 422, the driving wheel 421 still maintains the speed provided by the motor 41. The driven wheel 422 rotates faster due to the elastic force of the elastic element 3. Therefore, the driving wheel 421 and the driven wheel 422 disengage, the overrunning clutch 42 is disengaged, the elastic potential energy stored in the elastic element 3 is rapidly released, driving the swing arm 21 to swing from the second swing position to the first swing position. At the same time, the swing arm 21 pushes the driven wheel 422 to rotate rapidly, thereby driving the massage hammer 2 to achieve a rapid hammering action.

[0059] After the hammering action is completed, the motor 41 continues to rotate, and the first stop 423 on the driving wheel 421 contacts the second stop 424 on the driven wheel 422 again, starting the next energy storage stage. The above process is repeated to achieve continuous hammering massage action.

[0060] Second embodiment, see Figure 10 and Figure 11As shown: This embodiment is a one-to-two motor drive configuration. Compared to the first embodiment, the difference lies in the following: There are two massage hammers 2, spaced apart along the first axis L1. There are two elastic elements 3, each connected between the two swing arms 21 and the support base 1. The motor 41 is mounted on the support base 1 and located between the two massage hammers 2. There are two overrunning clutches 42 and two second shafts 44, respectively positioned between the motor 41 and the two massage hammers 2. There are two second bevel gears 432, meshing with opposite sides of the first bevel gear 431 and fixed to the two second shafts 44. The two swing arms 21 are simultaneously driven by one motor 41. Preferably, the pushing portions 425 of the two overrunning clutches 42 are located on opposite sides of the second axis L2, so that when the motor 41 is driven simultaneously, the two massage hammers 2 alternately strike each other, one up and one down. Figure 10 As shown: when one swing arm 21 is in the first swing position / second swing position, the other hammer head 22 is exactly in the second swing position / first swing position.

[0061] Third embodiment, see Figure 12 and Figure 13 As shown: This embodiment also uses a one-to-two motor drive, but differs from the second embodiment in that the elastic element 3 is a compression spring. In this embodiment, the bracket 11 is not limited to the U-shaped structure described in the first and second embodiments. The first end of the swing rod 21 only needs to be able to rotate around the first axis L1 and be connected to the bracket 11 to support the swing rod 21. The elastic element 3 is located on the swing plane of the swing rod 21, with one end fixed to the support base 1 and the other end fixed to the swing rod 21. Furthermore, the energy storage form of the elastic element 3 is different; the compression spring stores energy through compression or extension. The hammering motion process can be found in [reference needed]. Figures 14-17 As shown, Figure 14 The hammer-massage structure shown has the overrunning clutch engaged. Figure 15 The hammer-massage structure shown has an overrunning clutch in a critical state. Figure 16 The hammer-massage structure shown has the overrunning clutch disengaged. Figure 17 The hammer-massage structure shown has an overrunning clutch in the hammer-massage state.

[0062] Fourth embodiment, see Figure 18As shown: This embodiment also uses a one-motor-support-four-drive configuration. In this embodiment, it includes two hammer-massage structures as in the second embodiment, symmetrically arranged with a third axis L3 parallel to the first axis L1 as the center line. It should be noted that these two hammer-massage structures share the same motor 41. The motor shaft 411 of the motor 41 passes through the motor 41 and extends out at both ends to form shaft segments for connecting the reduction mechanisms 43 of the two hammer-massage structures. Since the four swing arms 21 are driven by the same motor 41, two swing arms 21 located on the same diagonal and two swing arms 21 on the other diagonal alternately hammer upwards and downwards.

[0063] Preferably, the swing arm 21 in the above embodiments can be configured as L-shaped to facilitate adjustment of the hammering direction of the hammer head 22. The connection between the hammer head 22 and the swing arm 21 can be a fixed connection or a rotatable connection achieved through an intermediate component such as a turntable, so that the hammer head 22 can rotate or change position while hammering. Furthermore, multiple hammer heads can be connected to one swing arm 21 through an intermediate component, further improving the user's massage experience.

[0064] Based on the above-mentioned hammer massage structure, a seat is provided, which is equipped with at least one hammer massage structure. The at least one hammer massage structure can adopt any one or more combinations of the above-mentioned motor-driven one-support-one-drive, motor-driven two-support, and motor-driven four-support structures.

[0065] Specifically, the hammer massage structure can be integrated into the backrest or seat cushion of the entire chair. More often, it is integrated and mounted on the back of the panel suspension 51 of the backrest 5, in conjunction with... Figures 19-21As shown, the suspension 51 is made of bent steel wire, and holes 52 are correspondingly opened on the foam of the backrest 5 for the hammer head 22 to pass through to achieve hammer massage. It should be noted that since the hammer massage structure occupies more space than the pneumatic system, especially the motor 41 and the transmission mechanism (including the overrunning clutch 42, the reduction mechanism 43 and the second shaft 44), the transmission structure requires a large amount of space and may interfere with the foam and frame. It may compress the foam or air duct, affecting the user experience. The interference problem needs to be solved by optimizing the miniaturization design of the hammer massage structure, shortening the transmission links (including the motor shaft 411 and the second shaft 44), using a compact motor 41, and reserving an installation position for the hammer massage structure on the seat frame. In addition, the hammering action will generate large mechanical vibrations, which may be transmitted to the seat frame or other components through the plate suspension 51, causing unnecessary noise or resonance problems (when the hammering frequency is close to the vibration frequency of the seat spring or the body, it may cause resonance and amplify the vibration effect). In order to reduce abnormal noise, damping and sound insulation materials, such as felt, can be added. The eight massage points, designed according to ergonomics (i.e., each of P1 to P8 is equipped with a massage hammer 2), can be used as follows: Figure 21 The massage points are arranged such that each point can be equipped with an independent motor 41, which, through a control unit, achieves a precise and comfortable massage effect. This motor 41 can be a DC brushless motor, which is small in size, low in noise, and has a long lifespan. Under the control of the control unit, various massage modes can be provided, such as full-back tapping, zone tapping, and point-to-point tapping. It also allows for adjustments including intensity, frequency, and timer functions.
