Description

Technical Field

[0001] This application relates to the field of automotive massage seat equipment technology, and more specifically, to a massage mechanism and a massage seat. Background Technology

[0002] With the rapid popularization of automobiles, people have higher demands for their travel experience. Adding massage mechanisms to car seats can effectively improve the user's travel experience and reduce fatigue during journeys. Currently, car seat massage primarily comes in two forms: airbag massage and mechanical massage. Airbag massage works by inflating airbags, using the rise and fall of the airbags to achieve a massage effect. Mechanical massage, on the other hand, uses mechanical mechanisms to drive massage heads to perform various massage techniques such as kneading. Its massage effect is better than airbag massage, and it can more realistically simulate a human hand massage. However, in emergency situations, mechanical massage may not collapse or collapse slowly, potentially causing harm to the user. Summary of the Invention

[0003] The purpose of this application is to provide a massage mechanism and a massage chair to address the shortcomings of the prior art.

[0004] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:

[0005] One aspect of this application provides a massage mechanism, including a mounting base and a massage head assembly, a kneading mechanism, an energy storage mechanism, and a collapse assembly disposed on the mounting base. The massage head assembly is rotatably disposed on the kneading mechanism and is connected to the energy storage mechanism. The energy storage mechanism drives the massage head assembly to rotate to a massage position and maintains an energy storage state. The collapse assembly is used to release the energy storage state of the energy storage mechanism, so that the energy storage mechanism releases energy and drives the massage head assembly to rotate from the massage position to a storage position.

[0006] Optionally, the energy storage mechanism includes a striking component and an energy storage element connected between the striking component and the mounting base. A guide rail is provided on the mounting base, and the striking component is slidably mounted on the mounting base via the guide rail. The striking component is driven to connect with the massage head component, and the collapsing component is configured to cooperate with the striking component.

[0007] Optionally, the energy storage mechanism further includes a first lifting assembly, which includes a sliding baffle slidably mounted on a guide rail, a lead screw fixedly mounted on the sliding baffle, and a lead screw motor fixedly mounted on the striking assembly. The lead screw motor is connected to the lead screw drive. A protrusion is fixedly mounted on the guide rail, and the collapsing assembly and the protrusion abut against opposite sides of the sliding baffle. The lead screw motor drives the striking assembly to slide along the guide rail, so that the energy storage component stores energy and drives the massage head assembly to rotate to the massage position. The collapsing assembly disengages from the sliding baffle, so that the energy storage component releases energy and drives the striking assembly and the first lifting assembly to slide relative to the guide rail. The striking assembly drives the massage head assembly to rotate from the massage position to the storage position.

[0008] Optionally, the collapse assembly includes a rotating stop rotatably mounted on the mounting base and a collapse actuator rotatably connected to the rotating stop. The collapse actuator is used to drive the rotating stop to rotate so as to disengage from the sliding baffle.

[0009] Optionally, the collapse assembly also includes an elastic reset member connected to the rotating block, the elastic reset member being used to apply force to the rotating block so that the rotating block tends to abut against the sliding baffle.

[0010] Optionally, the energy storage mechanism also includes a second lifting assembly, which includes an interconnected air source and an airbag. A baffle plate is also provided on the mounting base, and the airbag is positioned between the baffle plate and the striking assembly. The airbag is used to inflate and expand to drive the striking assembly to slide along the guide rail, so that the energy storage component stores energy and drives the massage head assembly to rotate to the massage position. The airbag also has a vent, and the collapse assembly includes a vent valve installed at the vent. The vent valve is used to deflate and contract the airbag, so that the energy storage component releases energy and drives the massage head assembly to rotate from the massage position to the storage position via the striking assembly.

[0011] Optionally, the kneading mechanism includes a kneading motor, a kneading reduction assembly, and a kneading shaft. The kneading motor is driven and connected to the kneading shaft via the kneading reduction assembly. An eccentric bushing is provided on the kneading shaft, and the massage head assembly is rotatably disposed on the outer periphery of the eccentric bushing.

[0012] Optionally, the massage head assembly includes a long curved arm rotatably mounted on the kneading mechanism and a short curved arm hinged to the long curved arm, and the tapping assembly is connected to the long curved arm and the short curved arm respectively via a ball joint.

[0015] The beneficial effects of this application include:

[0016] This application provides a massage mechanism and a massage seat, including a mounting base and a massage head assembly, a kneading mechanism, an energy storage mechanism, and a collapse assembly disposed on the mounting base. The massage head assembly is rotatably mounted on the kneading mechanism and is connected to the energy storage mechanism. The energy storage mechanism drives the massage head assembly to rotate to a massage position and maintains it in an energy-storing state. The collapse assembly is used to release the energy stored in the energy storage mechanism, allowing the energy storage mechanism to release energy and drive the massage head assembly to rotate from the massage position to a storage position. In emergency situations, such as sudden braking or collisions, the massage mechanism can actively release the energy stored in the energy storage mechanism using the collapse assembly, and use this energy as an aid to the collapse of the massage head assembly, causing it to collapse rapidly and preventing secondary injury to the human body.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] This application provides a massage chair and a massage mechanism used in the massage chair. The massage chair can be installed in any vehicle such as a car or airplane, allowing users to receive massage services through the massage mechanism while seated, thus effectively improving their travel experience. Furthermore, in emergency situations such as sudden braking or collisions, the massage mechanism can actively release energy stored in its energy storage mechanism using a collapsible component. This energy is then used to assist in the collapse of the massage head assembly, causing it to collapse rapidly and preventing secondary injury to the user. The embodiments of this application will be described below with reference to the accompanying drawings.

[0035] Please combine Figure 1 and Figure 7 As shown, a massage chair is provided, which includes a seat and a massage mechanism, wherein... Figure 1 and Figure 7 The portion shown is the seat backrest 1, on which a travel guide rail is provided, combined with... Figure 2 and Figure 8As shown, the massage mechanism is mounted to the guide rail via a walking drive mechanism 3 set on the mounting base 7. This allows the walking drive mechanism 3 to move along the guide rail when the user needs to massage different parts of their body, thereby moving the entire massage mechanism along the guide rail. Ultimately, the movement of the massage mechanism fulfills the user's needs for massaging different body parts. To improve the stability of the massage mechanism's movement, two parallel guide rails can be provided. It should be understood that the guide rails can be located in any part of the seat; for example, they can be located only on the seat surface, or only on the seat back, or simultaneously on both the seat surface and the backrest. This application does not impose any specific limitations on this.

[0036] Specifically, such as Figure 1 and Figure 7 As shown, the travel guide rail includes a support guide rail 2 and a travel rack 2a embedded in the support guide rail 2. Figure 2 and Figure 8 As shown, the walking drive mechanism 3 includes a walking motor 3a, a walking gearbox 3b, and a walking shaft 3c mounted on the mounting base 7. Walking gears 3d are respectively provided at both ends of the walking shaft 3c. The walking motor 3a is driven and connected to the walking shaft 3c via the walking gearbox 3b. The walking gears 3d mesh with the walking rack 2a. Thus, when the massage mechanism needs to move, the walking motor 3a can rotate through the walking shaft 3c, thereby causing the walking gears 3d to move along the extension direction of the walking rack 2a.

[0037] In order to achieve the overall movement of the massage mechanism, such as Figures 1 to 10 As shown, the massage mechanism can be mounted on the mounting base 7, with all its components installed on the base 7. To enable the massage mechanism to provide a certain massage function, such as... Figure 3 and Figure 9 As shown, the massage mechanism also includes a kneading mechanism 4 and a massage head assembly, so that the kneading mechanism 4 can drive the massage head assembly to achieve a kneading massage effect. Specifically, the kneading mechanism 4 includes a kneading motor 4a, a kneading reduction assembly 4b, and a kneading shaft 4c mounted on the mounting base 7. The kneading motor 4a is driven and connected to the kneading shaft 4c via the kneading reduction assembly 4b. Eccentric bushings 4g are fixedly installed at opposite ends of the kneading shaft 4c. The massage head assembly is rotatably mounted on the outer periphery of the eccentric bushings 4g. Thus, when kneading massage is required, the kneading motor 4a can drive the kneading shaft 4c to rotate, which in turn causes the massage head assembly to swing through the eccentric bushings 4g, thereby achieving the kneading massage effect.

[0038] Furthermore, such as Figure 3 and Figure 9As shown, the massage head assembly includes a long curved arm 4d and a short curved arm 4e. The long curved arm 4d is rotatably sleeved on the outer periphery of the eccentric bushing 4g, and the short curved arm 4e is hinged to the long curved arm 4d via a first screw shaft 4h (as shown). Figure 5 or Figure 10 Massage heads 4f are respectively installed at the top of the long curved arm 4d and the top of the short curved arm 4e. Thus, when the kneading motor 4a drives the kneading shaft 4c to rotate, the long curved arm 4d can be driven to oscillate through the eccentric bushing 4g. Since the short curved arm 4e is hinged to the long curved arm 4d, it also oscillates along with the long curved arm 4d. Therefore, the massage heads 4f at the top of both the long curved arm 4d and the short curved arm 4e jointly simulate a kneading massage technique. To improve the massage effect, such as... Figure 3 and Figure 9 As shown, the massage head assembly can be in two groups, each group including a long curved arm 4d and a short curved arm 4e, so that the massage head assemblies in the two groups are located at opposite ends of the kneading shaft 4c.

[0039] like Figure 3 and Figure 9 As shown, the massage mechanism also includes an energy storage mechanism 6 and a collapsible assembly 8 mounted on the mounting base 7. The energy storage mechanism 6 is connected to the massage head assembly so that the energy storage mechanism 6 can restrict the rotational freedom of the massage head assembly and prevent the massage head assembly from rotating unexpectedly around the kneading axis 4c.

[0040] When there is no need for massage, the massage head assembly can be recessed relative to the mounting base 7, i.e., in a position where... Figure 5 (b) or Figure 10 The storage position shown in (b) avoids contact between the massage head assembly and the user's body, improving the user's riding experience when not massaging. Furthermore, when a massage is needed, the energy storage mechanism 6 can simultaneously rotate the massage head assembly relative to the kneading shaft 4c during the energy storage process, causing the massage head assembly to rise upwards, i.e., rotate from the storage position to the massage position, as shown in (b). Figure 1 and Figure 5 (a) or Figure 7 and Figure 10 As shown in (a), when the massage head assembly is rotated to the massage position, the energy storage mechanism 6 remains in an energy-storing state. At this time, the massage head assembly protrudes slightly outward relative to the mounting base 7, allowing it to contact the user's body and provide a good massage effect. During the massage, in case of an emergency, the collapse component 8 can release the energy storage state of the energy storage mechanism 6, causing it to release energy. The released energy is then used to quickly retract the massage head assembly downward, from the massage position (the more outward-protruding position) to the retracted position (the more inward-retracting position). Figure 1 and Figure 5 (b) or Figure 7and Figure 10 As shown in (b) above, this increases the retraction speed of the massage head assembly, preventing secondary injury to the user. It should be understood that when the massage head assembly is in the massage position, it protrudes relative to the backrest or seat surface; when in the retracted position, it retracts relative to the backrest or seat surface, so the massage mechanism cannot be felt by the user during normal sitting.

[0041] To further enhance the massage effect, the energy storage mechanism 6 includes a tapping component 5 and an energy storage element 6d. The tapping component 5 is slidably mounted on the mounting base 7 via a guide rail. The energy storage element 6d is located between the tapping component 5 and the mounting base 7, so that energy can be stored in the energy storage element 6d when the tapping component 5 slides along the guide rail. The tapping component 5 is driven to the massage head assembly, and the collapsible component 8 is configured to cooperate with the tapping component 5. Thus, under the action of external force, the tapping component 5 can drive the massage head assembly to rotate from the storage position to the massage position, and in the process, it acts on the energy storage element 6d to store energy. The tapping component 5 itself can drive the massage head assembly to vibrate, simulating a tapping massage technique. In case of emergency, the collapsible component 8 can release the limit on the tapping component 5, causing the energy storage element 6d to release energy and drive the tapping component 5 to slide along the guide rail, thereby driving the massage head assembly to rotate from the massage position to the storage position.

[0042] like Figure 2 or Figure 8 As shown, the guide rail can be a guide rod 6c fixedly mounted on the mounting base 7. There can be two guide rods 6c, and the striking component 5 can be slidably mounted on the two guide rods 6c so that it can slide stably along the axial direction of the guide rods 6c. The energy storage component 6d can be a helical spring sleeved on the guide rod 6c. One end of the helical spring abuts against the mounting base 7, and the other end abuts against the striking component 5. Thus, when the striking component 5 slides along the guide rod 6c, the helical spring can store energy. In case of emergency, under the action of the collapse component 8, the helical spring releases energy, thereby pushing the striking component 5 to slide rapidly, so as to drive the massage head assembly to rotate from the massage position to the storage position.

[0043] Please continue to refer to Figures 2 to 10As shown, the tapping assembly 5 may include a tapping motor 5a and an eccentric shaft 5b. The tapping motor 5a can be slidably mounted on the guide rod 6c via the base. The tapping motor 5a is driven by the eccentric shaft 5b. Bearing seats 5f are respectively provided at opposite ends of the eccentric shaft 5b. When the tapping motor 5a drives the eccentric shaft 5b to rotate, it will cause the bearing seats 5f to vibrate. For a set of massage head assemblies, a ball joint groove is provided on the long curved arm 4d. The ball joint end of the first ball joint connecting rod 5c is installed in the ball joint groove of the long curved arm 4d. The other end of the first ball joint connecting rod 5c is hinged to the bearing seat 5f via the second screw shaft 5g. A ball joint groove is provided on the short curved arm 4e. The ball joint end of the second ball joint connecting rod 5d is installed in the ball joint groove of the short curved arm 4e. The other end of the second ball joint connecting rod 5d is fixed to the inner ring of the spherical bearing 5h. The outer ring of the spherical bearing 5h is fixed to the end of the fixed shaft 5e of the base. Another set of massage head assemblies can be configured similarly. Therefore, when the user needs a tapping massage, the tapping motor 5a drives the eccentric shaft 5b to rotate, which in turn causes the bearing seat 5f to vibrate. This, in turn, causes the long curved arm 4d to vibrate along the eccentric bushing 4g via the first ball joint 5c, and then drives the short curved arm 4e to vibrate via the first screw shaft 4h. The vibration of the long curved arm 4d and the short curved arm 4e causes the massage head 4f mounted on top of both to vibrate, thus simulating a tapping massage technique.

[0044] The collapsible component 8 and the energy storage mechanism 6 in this application can have various structural forms. For ease of understanding, two of them will be described schematically below.

[0045] In one implementation, such as Figure 1 As shown, the massage mechanism is installed in the seat and can move along the seat to achieve massage in different positions. Based on this, as... Figures 2 to 4 As shown, the energy storage mechanism 6 includes a first lifting assembly, which includes a sliding baffle 8a, a lead screw 6b, and a lead screw motor 6a. The sliding baffle 8a is slidably mounted on the guide rod 6c, and one end of the lead screw 6b is fixed to the sliding baffle 8a. The lead screw motor 6a is driven by the lead screw 6b and is fixedly connected to the striking assembly 5. A protrusion 6c1 is fixedly mounted on the guide rod 6c. The collapsing assembly 8 and the protrusion 6c1 respectively abut against opposite sides of the sliding baffle 8a, thereby fixing the sliding baffle 8a relative to the guide rod 6c. Thus, combined with... Figure 5 As shown, when the massage head assembly is in the retracted position and the user needs a massage, the lead screw motor 6a can drive the striking component 5 to slide along the guide rod 6c in a direction away from the protrusion 6c1. During this process, the striking component 5 causes the energy storage component 6d to store energy and drive the massage head assembly to rotate from the retracted position to the massage position, i.e. Figure 5As shown in (a), the massage head assembly is designed to contact the user's body, thereby enabling the massage head assembly to perform various massage techniques such as kneading and patting via the tapping motor 5a and / or the kneading motor 4a. After the massage, the tapping assembly 5 can be slid along the guide rod 6c towards the protrusion 6c1 via the lead screw motor 6a. During this process, as the tapping assembly 5 moves, the energy storage component 6d gradually releases energy, and the tapping assembly 5, through the first ball joint 5c and the second ball joint 5d, rotates the massage head assembly from the massage position to the storage position, i.e., as shown in (a). Figure 5 As shown in (b), the massage head assembly is retracted to avoid contact with the user's body and prevent any foreign body sensation during use. When the massage head assembly is in the massage position and an emergency occurs, the collapsible assembly 8 can release its contact with the sliding baffle 8a. At this time, the sliding baffle 8a has a degree of freedom of movement. Therefore, the energy storage component 6d begins to release energy and drives the striking assembly 5 and the first lifting assembly to slide relative to the guide rod 6c toward the protrusion 6c1. This causes the striking assembly 5 to quickly rotate the massage head assembly from the massage position to the storage position, achieving rapid collapse while avoiding injury to the user.

[0046] In this embodiment, such as Figure 6 As shown, the collapse assembly 8 includes an elastic reset member, a rotating stop 8c, and a collapse actuator 8f. The rotating stop 8c is rotatably mounted on the mounting base 7 via a third screw shaft 8d. The elastic reset member is a torsion spring 8e, with one end of the torsion spring 8e abutting against the mounting base 7 and the other end of the torsion spring 8e abutting against the rotating stop 8c. Thus, the elastic reset member provides a force to the rotating stop 8c, causing the rotating stop 8c to tend to abut against the sliding baffle 8a. Because the rotating stop 8c abuts against the sliding baffle 8a, and in conjunction with the protrusion 6c1, the sliding baffle 8a can be limited, making it fixed and unable to slide relative to the guide rod 6c. In an emergency, the collapsible actuator 8f can drive the rotating baffle to rotate (during which the torsion spring 8e stores energy), thereby releasing the rotating baffle from the sliding baffle 8a. The energy released by the energy storage component 6d causes the striking assembly 5 and the first lifting assembly to slide relative to the guide rod 6c toward the protrusion 6c1, thus pulling the massage head assembly quickly from the massage position to the storage position. The collapsible actuator 8f can be an electromagnetic actuator; that is, in an emergency, the push rod of the electromagnetic actuator can push the rotating stop 8c to rotate, thereby releasing it from the sliding baffle 8a.

[0047] In this embodiment, such as Figure 3 As shown, the mounting base 7 has a fixed baffle 8b, which is fixed to the tail ends of the two guide rods 6c. This allows the rotating block 8c to be rotated and installed onto the fixed baffle 8b via the third screw shaft 8d.

[0048] After the collapse ends, combined Figures 3 to 6To facilitate the reset of the massage mechanism, the lead screw motor 6a can drive the lead screw 6b to rotate. At this time, the base of the striking component 5 will abut against the side of the protrusion 6c1 away from the sliding baffle 8a. Through interaction, the lead screw 6b drives the sliding baffle 8a to move towards the protrusion 6c1 until the sliding baffle 8a abuts against the protrusion 6c1. Then, the rotating block 8c will abut against the sliding baffle 8a again under the action of the elastic reset component. That is, the rotating block 8c cooperates with the protrusion 6c1 to fix the sliding baffle 8a again. At this time, the lead screw motor 6a can drive the massage head assembly to switch between the storage position and the massage position.

[0049] In another implementation, such as Figure 7 As shown, the massage mechanism is also installed on the seat and can move along the seat to achieve massage in different positions. Based on this, as... Figures 8 to 10 As shown, the energy storage mechanism 6 also includes a second lifting assembly, which includes an interconnected inflation source (not shown) and an airbag 6e. A baffle plate is also provided on the mounting base 7, and the airbag 6e is positioned between the baffle plate and the striking assembly 5. The inflation source can inflate the airbag 6e through an inflation port 6e1. The airbag 6e also has a vent 6e2, and the collapse assembly 8 includes a vent valve installed at the vent 6e2. When there is no massage demand, the airbag 6e can be de-inflated, and the striking assembly 5, under the action of the energy storage component 6d, pulls the massage head assembly to the retracted position, as shown. Figure 10 As shown in (b), this arrangement prevents the massage head assembly from contacting the user's body. When a massage is needed, air can be injected into the airbag 6e from the air source. The airbag 6e gradually expands, thereby pushing the tapping component 5 to slide along the guide rod 6c. This, in turn, drives the energy storage component 6d to store energy and rotates the massage head assembly from the storage position to the massage position, as shown in (b). Figure 10 The state shown in (a) allows the massage head assembly to easily contact the user's body, thereby providing the corresponding massage function. In case of an emergency, the vent valve can be opened, the airbag 6e can be contracted, thereby releasing the energy storage component 6d, which in turn drives the massage head assembly from the massage position to the storage position via the tapping component 5.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
