Description

Technical Field

[0001] The present invention relates to the technical field of vehicle seats, in particular to an auxiliary massage device for automobile seats. Background Art

[0002] Car seat auxiliary massage equipment is a device installed in the car seat, which provides massage services to the driver and passengers through various technical means to relieve fatigue and relax the body. The main massage methods are as follows:

[0003] Pneumatic massage: An air pump generates compressed air, which is then controlled by valves to inflate and deflate air bags within the seat back or cushion, simulating compression and kneading movements. This allows for a wave-like massage, with the air bags inflating and deflating in sequence, creating a wave-like motion that soothes the back muscles. Alternatively, a segmented massage can be performed, dividing the seat's massage area into several sections, such as shoulders, chest, and waist. By controlling the inflation and deflation of air bags in different sections, pressure and relaxation are achieved in these sections.

[0004] Electromechanical massage: Utilizing a motor to drive mechanical components, such as steel cables, sliding modules, and metal springs, the massage contacts or plates within the seat move. For example, the motor pulls the steel cables, causing the connected sliding modules to reciprocate, driving the metal springs and plastic adjustment plates to extend and retract, massaging areas such as the waist. Alternatively, the motor can drive an eccentric wheel or cam mechanism to vibrate, achieving vibration massage.

[0005] Electronic oscillation massage: The electronic oscillator is controlled by a computer integrated into the seat. The vibration frequency, amplitude and rhythm of the massage parts are precisely adjusted according to the preset program to produce different massage effects. It can simulate a variety of delicate massage movements such as acupressure and patting.

[0006] In the process of performing massage operations through electromechanical drive, the mechanical structure of the electromechanically driven massage device is relatively fixed, and the vibration of the massage contacts is directly driven by the motor, which is difficult to flexibly adjust according to the real-time seat leaning state during movement. The massage contacts cannot independently control whether to vibrate according to the actual seat leaning state of the user on the seat, and the massage contacts that are not in contact maintain the same vibration, which consumes unnecessary electricity and increases the energy consumption of the car seat auxiliary massage device. For this reason, we propose an automobile seat auxiliary massage device. Summary of the Invention

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1-11 The car seat auxiliary massage device shown in the figure includes a mounting shell 102 fixed to the inner side of the seat body 101, and further includes:

[0035] A partition 2 is fixed to the interior of the mounting housing 102, and the interior of the mounting housing 102 is divided into an operating chamber and a pressure chamber by the partition 2. The operating chamber is arranged toward the front side of the seat body 101, and a support component and a vibration component for auxiliary massage are arranged between the front side of the mounting housing 102 and the operating chamber;

[0036] The support assembly is evenly distributed on the front side of the mounting shell 102, and the support assembly includes a mounting hole 301 opened on the front side of the mounting shell 102, and the mounting hole 301 is communicated with the interior of the operating chamber. A rubber ring 304 is fixed to the interior of the mounting hole 301, and a massage contact 302 is slidably connected to the inner side of the rubber ring 304. One end of the massage contact 302 is located on the front side of the mounting shell 102, and the other end of the massage contact 302 is located inside the operating chamber and is connected to the piston rod 303 through a connecting assembly. Multiple groups of fixed cylinders 5 are fixed on the partition 2, and an elastic telescopic assembly for telescopically connecting the piston rod 303 is provided on the fixed cylinder 5. A control assembly for controlling the pressure supply to the piston rod 303 is provided between the fixed cylinder 5 and the piston rod 303. A piston plate 9 for squeezing the internal gas is slidably connected to the interior of the pressure chamber. The piston plate 9 and the interior of the pressure chamber are matched with each other, and a pushing assembly for pushing the piston plate 9 is provided on the mounting shell 102;

[0037] It should be noted here that when the car seat auxiliary massage device is in use, through the mutual cooperation of components such as the support component, vibration component, elastic expansion component, control component and pushing component, each group of massage contacts 302 after offsetting each other can adapt to the contour of the offset position of the user's back, so as to better fit the curve of the human back and ensure comprehensive and close contact with the back, and the massage contacts 302 can also be offset and vibrated with the corresponding position of the user's back with a certain extrusion force to achieve a full massage effect, and during the vibration process, the massage contacts 302 at the corresponding position can autonomously control whether to vibrate according to whether the actual user contacts the chair back, thereby avoiding the vibration of the massage contacts 302 that are not offset to generate unnecessary electricity, thereby reducing the energy consumption of the car seat auxiliary massage device.

[0038] Preferably, the connecting assembly includes a connecting rod 401 fixed to one end of the piston rod 303, and the connecting rod 401 is flexibly connected to the opposite end of the massage contact 302 via a rubber block 402;

[0039] It should be noted that the connecting rod 401 and the rubber block 402 facilitate the flexible connection between the piston rod 303 and the massage contact 302 .

[0040] Preferably, the elastic telescopic component includes a mounting groove 601 provided inside the fixed cylinder 5, the piston rod 303 is slidably connected to the inside of the mounting groove 601, two sets of sleeves 602 are symmetrically fixed inside the mounting groove 601, and the telescopic rod 603 is slidably connected to the two sets of sleeves 602, one end of the telescopic rod 603 is fixed to one end of the piston rod 303, and a spring 604 is sleeved on the outer side of the sleeve 602, and the two ends of the spring 604 are respectively arranged to abut against the piston rod 303 and the inner wall of the mounting groove 601, and a travel limit component for assisting in limiting the travel of the telescopic movement is provided on the sleeve 602;

[0041] It should be noted here that: the user's back is in contact with the massage contact 302 at the corresponding position on the mounting shell 102, pushing the massage contact 302 toward the inside of the operating chamber for contraction movement. As the massage contact 302 moves, the piston rod 303 is pushed to contract toward the inside of the mounting groove 601 of the fixed cylinder 5 through the connection between the rubber block 402 and the connecting rod 401. During the movement of the piston rod 303, the blocking plate 803 is driven to move synchronously and the through hole 804 on the blocking plate 803 is in a state of communication with the opening 802. During the contraction movement of the massage contact 302 and the piston rod 303, the telescopic rod 603 is pushed to slide on the sleeve 602 and the spring 604 is deformed by force to generate elastic force. Through the elastic force of the spring 604 and the connection between the piston rod 303, the connecting rod 401 and the rubber block 402, an extrusion force is generated on the massage contact 302, so that the massage contact 302 remains in contact with the user's back rest position.

[0042] Preferably, the travel limit assembly includes two sets of limit slots 701 provided on the sleeve 602, the limit slots 701 are slidably connected to the slide pins 702, and the two sets of slide pins 702 are symmetrically fixed on the telescopic rod 603;

[0043] It should be noted here that: during the movement of the telescopic rod 603 , the sliding pin 702 is driven to move synchronously. During the movement of the sliding pin 702 , the sliding stroke of the sliding pin 702 is limited by the limiting sliding groove 701 .

[0044] Preferably, the control assembly includes an annular cavity 801 formed on the fixed cylinder 5, the annular cavity 801 communicating with the interior of the pressure chamber, an opening 802 for gas circulation being formed between the annular cavity 801 and the mounting groove 601, a blocking plate 803 fixed at one end of the piston rod 303 for abutting against and blocking the opening 802, and a through hole 804 for gas circulation control being formed on the blocking plate 803;

[0045] It should be noted here that: the user's back abuts against the massage contacts 302 at the corresponding positions on the mounting housing 102, pushing the massage contacts 302 toward the inside of the operating chamber for contraction movement. As the massage contacts 302 move, the connection between the rubber block 402 and the connecting rod 401 pushes the piston rod 303 toward the inside of the mounting groove 601 of the fixed cylinder 5 for contraction movement. During the movement of the piston rod 303, the blocking plate 803 is driven to move synchronously, and the through hole 804 on the blocking plate 803 is in a state of communication with the opening 802, so that part of the gas in the pressure chamber can enter the inside of the mounting groove 601 during the subsequent movement of the piston plate 9.

[0046] It is worth noting here that: when the massage contact 302 is not squeezed and pushed, the opening 802 is blocked by the blocking plate 803, so that the massage contact 302 that is not in contact will not be inflated and pressurized, and through the blocking effect, the communicating position can be squeezed and pushed more efficiently during the air supply extrusion process.

[0047] Preferably, the vibration assembly includes a vibration plate 1201 disposed inside the operating cavity. A vibrator 1202 for generating vibration is mounted on the vibration plate 1201. The vibration plate 1201 is flexibly connected to the inner wall of the operating cavity via a rubber plate 1203. The vibration plate 1201 is provided with multiple groups of connection holes 1204 for engaging and transmitting with the massage contacts 302. Each group of connecting rods 401 is located inside each group of connection holes 1204.

[0048] It should be noted that the user's back abuts against the massage contacts 302 at corresponding positions on the mounting housing 102, pushing the massage contacts 302 toward the interior of the operating chamber and causing them to retract. The massage contacts 302 are then snapped into the connection holes 1204 of the vibration plate 1201, and the vibration plate 1201 is driven to vibrate by the vibrator 1202. During the vibration of the vibration plate 1201, the massage contacts 302 are also vibrated due to the snap connection between the massage contacts 302 and the connection holes 1204.

[0049] It is worth noting here that the vibrator 1202 is a conventional technical component for generating vibration, and its working principle and operation method are considered as prior art in this application and will not be described in detail.

[0050] It should be noted here that the rubber plate 1203 facilitates the flexible connection between the vibration plate 1201 and the inner wall of the operating cavity.

[0051] Preferably, the outer diameter of the connecting rod 401 is smaller than the outer diameter of the connecting hole 1204;

[0052] It should be noted here that the size is set so that the vibration plate 1201 does not drive the connecting rod 401 to move when it vibrates.

[0053] Preferably, the pushing assembly includes a U-shaped frame 1001 fixed to the outside of the mounting shell 102, a threaded tube 1002 is slidably connected to the mounting shell 102, one end of the threaded tube 1002 is fixed to the piston plate 9, a threaded rod 1003 is threadedly engaged with the threaded tube 1002, a driving motor 1004 for driving the threaded rod 1003 is installed on the U-shaped frame 1001, a sleeve 1005 is slidably connected to the mounting shell 102, one end of the sleeve 1005 is fixed to the piston plate 9, a sliding rod 1006 is slidably connected to the sleeve 1005, and one end of the sliding rod 1006 is fixed to the U-shaped frame 1001;

[0054] It should be noted here that: the threaded rod 1003 is driven to rotate by driving the motor 1004. During the rotation of the threaded rod 1003, the piston plate 9 is moved inside the pressure chamber through the mutual engagement transmission between the threaded rod 1003 and the threaded tube 1002 and the sliding guiding effect of the sleeve 1005 and the slide rod 1006.

[0055] Preferably, a pressure relief valve 11 is installed on the mounting housing 102 for relieving pressure inside the pressure chamber during the boosting process;

[0056] It should be noted that the piston plate 9 pushes the pressure in the pressure chamber and the fixed cylinder 5 connected to the pressure chamber to gradually increase, and the pressure on the massage contacts 302 and the user's back is increased synchronously through transmission. During the pressurization process, when the pressure value in the pressure chamber reaches the pressure relief value of the pressure relief valve 11, the pressure is relieved through the pressure relief valve 11, so that the pressure of the massage contacts 302 on the user's back no longer increases, thereby avoiding excessive squeezing force causing discomfort to the user.

[0057] It is worth noting here that the pressure relief valve 11 is a conventional operating component for controlling the pressure value, and its working principle and usage are regarded as the prior art in this application and will not be elaborated on here.

[0058] In this solution: A car seat auxiliary massage device includes the following steps:

[0059] When the car seat auxiliary massage device is in use, the mounting shell 102 is mounted inside the car seat. After mounting, the user sits on the car seat and tilts the seat back toward the mounting shell 102. During the tilting process, the user's back abuts against the front end of the massage contact 302 at the corresponding position on the front side of the mounting shell 102. During the abutment process, the massage contact 302 is pushed to contract inside the rubber ring 304 toward the inside of the operating chamber. The massage contacts 302 at different positions abut against the user's back with different forces, causing the massage contacts 302 to contract to different lengths. Through the corresponding contraction movement of each group of abutting positions, the massage contacts 302 of each group after abutting adapt to the contour of the abutting position of the user's back, so as to better fit the curve of the human back and ensure full and close contact with the back, making the massage more comfortable and uniform, and avoiding local poor contact or uneven pressure.

[0060] The user's back abuts against the massage contact 302 at the corresponding position on the mounting shell 102, pushing the massage contact 302 toward the inside of the operating chamber for contraction movement. As the massage contact 302 moves, the piston rod 303 is pushed toward the inside of the mounting groove 601 of the fixed cylinder 5 for contraction movement through the connection between the rubber block 402 and the connecting rod 401. During the movement of the piston rod 303, the blocking plate 803 is driven to move synchronously and the through hole 804 on the blocking plate 803 is in a state of communication with the opening 802. During the contraction movement of the massage contact 302 and the piston rod 303, the telescopic rod 603 is pushed. The sleeve 602 slides and deforms the spring 604 to generate elastic force. The elastic force of the spring 604 and the connection between the piston rod 303, the connecting rod 401 and the rubber block 402 generate an extrusion force on the massage contact 302, so that the massage contact 302 is kept against the user's backrest position. During the chair leaning process, the piston plate 9 is pushed by the pushing component to move toward the partition 2 in the pressure chamber. During the movement, the piston plate 9 squeezes the gas inside the piston chamber, so that part of the gas is transported to the inside of the mounting groove 601 through the annular cavity 801, the opening 802 and the through hole 804 (see Figure 11 The gas entering the mounting groove 601 generates a thrust on the piston rod 303 and the massage contact 302 under the action of pressure. The elastic force of the spring 604 inside the mounting groove 601 and the pressure of the gas keep the massage contact 302, after being contracted and squeezed, against the corresponding position of the back of the user's chair backrest, thereby ensuring the subsequent massage effect.

[0061] When the user's back abuts against the massage contact 302 at the corresponding position on the mounting housing 102, the massage contact 302 is pushed toward the inside of the operating cavity and contracts, so that the massage contact 302 is stuck into the connection hole 1204 of the vibration plate 1201 (see FIG. Figure 11In the state of the user's back, the vibrator 1202 drives the vibration plate 1201 to vibrate. During the vibration of the vibration plate 1201, the massage contacts 302 are connected to the connection holes 1204 by a force applied to the massage contacts 302, causing the massage contacts 302 to vibrate. Because the massage contacts 302 are kept against the corresponding positions on the user's back by the elastic force and gas pressure, the vibration of the massage contacts 302 achieves a sufficient massage effect on the corresponding positions on the user's back.

[0062] When the user sits on the car seat and tilts the seat back toward the mounting housing 102, the massage contacts 302 on the mounting housing 102 that are not in contact with the user's back do not retract (see FIG. Figure 10 state), so that the massage contact 302 at this position is not inserted into the interior of the connecting hole 1204 and does not move with the vibration of the vibration plate 1201, so that the massage contact 302 at the corresponding position can autonomously control whether to perform the vibration operation according to whether the actual user contacts the chair back, thereby avoiding the vibration of the massage contacts 302 that are not offset to generate unnecessary electrical energy, and reducing the energy consumption of the auxiliary massage equipment of the car seat.
