Description

Technical Field

[0001] This invention belongs to the field of massager technology, and particularly relates to a car massage device based on a release and collapse mechanism. Background Technology

[0002] Currently, during the use of in-vehicle massage devices, due to the bumps in the vehicle, sudden braking, or changes in the user's posture, the occupant's body moves backward due to inertia, and the protruding massage arms may cause concentrated impact injury to the occupant's back. If it does not have an automatic collapse function, it may actually aggravate the occupant's injury.

[0003] In the existing technology, although some massage devices are equipped with safety protection structures, most of them only achieve collapse avoidance by swinging and unfolding the massage arms. However, the swinging and unfolding of the massage arms has an upper limit angle. Under a large impact, the massage end of the massage arm will still press against the back of the occupant, which still poses a certain impact risk. Other safety protection methods that use electrical sensors or complex mechanical linkages have problems such as response delay, complex structure, and difficulty in resetting. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a car massage device based on a tripping and collapsing mechanism, which can quickly disengage when the massage arm is subjected to abnormal pressure, thus solving the problem of impact caused by the massage arm pressing against the back of the passenger when the passenger hits the back massage device.

[0005] The technical solution of the present invention: A car massage device based on a tripping and collapsing mechanism, comprising a base and a massage assembly, wherein the massage assembly includes a massage arm, a kneading motor for driving the massage arm to perform kneading massage actions, and a tapping motor for driving the massage arm to perform tapping massage actions. A lifting base is slidably disposed on the base, and a nut seat is disposed on the lifting base. An adjustment assembly is disposed on the lifting base to drive the nut seat to slide or lock relative to the lifting base. A first limit and a second limit are integrally or relatively fixedly disposed on the lifting base and the base, respectively, to constrain the sliding distance of the nut seat. The first limit is closer to the kneading base than the second limit. After the adjustment assembly drives the nut seat to slide relative to the base, it abuts against the first limit or the second limit. A tapping shaft is rotatably connected to the nut seat, and a connecting rod is disposed between the tapping shaft and the massage arm. The device also includes a kneading base and a collapsing assembly, wherein the kneading base is rotatably connected to the base, and the end near the lifting base is a swing end. A kneading shaft is rotatably disposed on the kneading base, and the massage arm is disposed on the kneading shaft.

[0006] The collapsible assembly includes an elastic element and a latching assembly for locking or unlocking the lifting base as it slides on the base. The two ends of the elastic element are connected to the base and the kneading base, respectively, to limit the swing of the kneading base. When the massage arm is abnormally compressed, the kneading base swings relative to the base, the elastic element deforms elastically and stores energy, the kneading base squeezes and unlocks the latching assembly, the striking shaft slides together with the lifting base, and the connecting rod drives the massage arm to swing around the kneading shaft.

[0007] By employing the above technical solution, the massage arm is stably supported during normal massage by locking the buckle assembly and cooperating with the elastic element. When subjected to abnormal pressure exceeding the pre-tension of the elastic element, the external force acts on the massage arm, causing the kneading base supporting the massage arm to rotate around the base, and the buckle assembly unlocks. The striking shaft is pushed by the massage arm and the connecting rod, and the lifting base slides, achieving collapse. During this collapse, the massage arm swings and unfolds with the lifting base, quickly detaching from contact with the user, thus improving safety. In particular, during the action of the massage arm being subjected to abnormal pressure, the pressure is transmitted to the kneading shaft, which drives the kneading base to swing. As a result, the entire massage arm can move away with the kneading shaft. Therefore, the swinging and unfolding of the massage arm and the moving away action during the collapse are carried out simultaneously, greatly reducing the probability of the massage end hitting the back of the occupant and causing impact injury in the event of an impact.

[0008] The specific working principle is as follows: Under normal working conditions, the fastening components are locked together, and the lifting base is relatively fixed to the base. When the adjusting component is locked, the lifting base and the nut seat are relatively fixed to the base. The kneading motor and the tapping motor control the massage arm to perform kneading and tapping massage actions. When the adjusting component is activated, the nut seat slides relative to the lifting base. The nut seat moves between the first limit and the second limit, which drives the tapping shaft to move relative to the base, changing the distance between the tapping shaft and the kneading shaft. The lifting angle of the massage arm is adjusted through the connecting rod.

[0009] During the collapse action, the adjustment component is locked, the buckle component is unlocked, the nut seat and the lifting base are fixed relative to each other, and the two slide on the base after being subjected to the force transmitted by the striking shaft until the nut seat abuts against the second limit on the base, realizing the massage arm unfolding and flattening;

[0010] During adjustment and reset, after the collapse, the nut seat rests against the second limit. After losing external pressure, the kneading base is reset by the tension of the elastic component. At this time, the adjustment component is activated, which drives the nut seat and the lifting base to move towards each other. Because the nut seat is constrained by the second limit, the lifting base moves towards the kneading shaft, and the fastening component re-fastens and locks, completing the reset after the collapse.

[0011] A further feature of the present invention is that the adjustment assembly includes a transmission shaft rotatably connected to the lifting base and an adjustment motor for driving the transmission shaft to rotate. A nut is fixedly provided on the nut seat. The transmission shaft includes a threaded section that is threadedly connected to the nut. The rotation of the transmission shaft causes the nut and the nut seat to move axially along the transmission shaft. The sliding direction of the lifting base on the base is parallel to the axial direction of the transmission shaft.

[0012] With the above-mentioned further settings, the movement or locking between the lifting base and the nut seat is achieved by threaded locking, which has high precision and good stability.

[0013] A further provision of the present invention: the buckle assembly includes an upper buckle disposed on the lifting base and a lower buckle disposed on the base. When the upper buckle and the lower buckle are engaged and locked, the lifting base slides and locks on the base.

[0014] The upper buckle includes a buckle groove, and the lower buckle is located in the buckle groove. The side wall of the buckle groove abuts and locks against the wall of the lower buckle. After the kneading base swings and squeezes the upper buckle, the upper buckle tilts and deforms, and the lower buckle disengages from the buckle groove to unlock.

[0015] With the above-mentioned further design, the upper buckle is designed to tilt and deform under pressure. This, combined with the swinging and pushing action of the kneading base plate, achieves precise control of the collapse trigger threshold, enabling the lower buckle to disengage from the buckle slot and unlock. There are no additional moving parts, resulting in good durability. During reset, after the lower buckle falls into the buckle slot, its elastic tilting deformation allows it to automatically reset. After reset, the sliding of the lifting base causes the side wall of the buckle slot to abut against the wall of the lower buckle. This mechanical locking method locks the lifting base, making it more stable under normal working conditions.

[0016] A further embodiment of the present invention includes: the striking shaft having a middle section and eccentric sections on both sides of the middle section; the output end of the striking motor being connected to the middle section for transmission; and a connecting member being rotatably disposed on the eccentric section, the connecting member being hinged to one end of the connecting rod.

[0017] By adopting the above-mentioned further configuration, through the design of the eccentric section, the connecting piece moves radially in the striking shaft to push the connecting rod to realize the swinging and striking of the massage arm.

[0018] A further embodiment of the present invention includes: the kneading shaft comprising a transmission section and two inclined sections located at both ends of the transmission section; the central axis of the inclined section has an inclination angle with the rotation axis of the transmission section; the massage arm is rotatably mounted on the inclined section; and the output end of the kneading motor is connected to the transmission section via a transmission connection.

[0019] With the above-mentioned further configuration, the central axis of the inclined section is set eccentrically. When the kneading shaft is driven to rotate as a whole by the kneading motor, its massage arm not only rotates around the axis of the transmission section, but also rotates around its own axis on the inclined section. The combined action of the two makes the outer end of the massage arm have an upward movement in the kneading shaft axis, so that the two massage arms simulate a kneading massage action that both swings and applies pressure in the middle.

[0020] A further embodiment of the present invention includes: one end of the connecting rod is a ball end, and the other end is hinged to the connector; the massage arm is provided with a spherical connecting hole, and the ball end of the connecting rod is movably installed in the spherical connecting hole of the massage arm.

[0021] The further design of the connecting rod ball end and the spherical connection hole of the massage arm allows the massage arm to move flexibly in multiple directions. This allows the connecting rod to adapt to the swing of the massage arm during kneading, ensuring the transmission of the tapping action. At the same time, this universal connection eliminates the additional stress caused by installation errors or motion interference, improving the system reliability and lifespan. Furthermore, in the event of collapse, the ball end connection can adapt to the angle change of the massage arm, ensuring a smooth release process without jamming.

[0022] The invention is further configured such that each inclined segment is provided with two massage arms, each massage arm is connected to a corresponding connecting rod, and the two connecting rods respectively push the two massage arms to swing in opposite directions.

[0023] With the above-mentioned further design, the reverse swinging design of the dual massage arms can simulate the alternating kneading of both hands, increasing the massage coverage area and comfort, and improving the user experience. This design realizes an alternating action similar to pinching and releasing, which is closer to the rhythm of a real massage. At the same time, the reverse movement can cancel out some vibrations, improve the stability of system operation, and is especially suitable for vibration-sensitive in-vehicle environments.

[0024] A further embodiment of the present invention includes a frame and a traveling assembly. The base moves on the frame via the traveling assembly. The traveling assembly includes a first traveling shaft and a second traveling shaft rotatably mounted on the base. The kneading base is rotatably mounted on the first traveling shaft and rotates around the central axis of the first traveling shaft. The transmission section is connected to the first traveling shaft or the second traveling shaft.

[0025] With the above-mentioned further configuration, the walking component allows the massage device to move and massage along the user's back or legs, realizing a massage mode that combines fixed-point and mobile massage, improving functionality and practicality. This structure integrates the massage module with the walking mechanism, realizing automatic positioning and area coverage massage, which is especially suitable for the space of car seats; driven directly by the walking shaft, the transmission path is short and the structure has good rigidity, ensuring the massage stability during movement.

[0026] In a further embodiment of the present invention: two traveling gears are provided on the first or second traveling shaft connected to the transmission section; racks are provided on both sides of the frame; each traveling gear is meshed with the corresponding rack; tracks are also provided on the left and right sides of the frame; and traveling wheels are provided at both ends of the first and second traveling shafts, and the traveling wheels roll in the tracks on the left and right sides of the frame.

[0027] With the above-mentioned further configuration, the combination of gear rack and track rollers achieves smooth, low-noise walking motion, with a stable structure suitable for vehicle vibration environments, ensuring the accuracy and continuity of the massage path. The gear rack transmission provides precise displacement control and sufficient driving torque to adapt to changes in seat tilt angle; the track and walking wheels form a dual guiding and load-bearing system to prevent the device from deviating or getting stuck, ensuring long-term reliable operation under vehicle vibration.

[0045] like Figure 1-12 As shown, a car massage device based on tripping and collapsing includes a base 1, a walking component, a kneading base 2, a lifting base 3, a nut seat 4, a massage component 5, and a collapsing component.

[0046] The base 1 is movably mounted on the frame 10 via a walking assembly. The walking assembly includes a first walking shaft 12 and a second walking shaft 13 rotatably mounted on the base 1. Racks 15 and tracks are provided on both the left and right sides of the frame 10. A walking gear 14 is fixedly mounted on each side of the first walking shaft 12. The walking gear 14 meshes with the racks 15 on both sides of the frame 10. At the same time, a walking wheel 16 is provided at both ends of the first walking shaft 12 and the second walking shaft 13. The walking wheel 16 rolls in the tracks on both sides of the frame 10. Thus, by driving the first walking shaft 12 or the second walking shaft 13 to rotate, the entire base 1 and the massage mechanism mounted on it can be moved smoothly along the frame 10 to achieve adjustment of the massage position.

[0047] One end of the kneading base 2 is rotatably connected to the base 1 via the first traveling shaft 12, so that the kneading base 2 can swing with the shaft as the fulcrum, and the other end is a free swing end, which is set close to the lifting base 3.

[0048] The massage component 5 includes a massage arm 53, a kneading motor 51 that drives the massage arm 53 to perform kneading massage actions, and a tapping motor 52 that drives the massage arm 53 to perform tapping massage actions. The end of the massage arm 53 is a massage end for contacting the human body, and a spherical connection hole 58 is provided near the middle or at the other end.

[0049] The massage assembly also includes a kneading shaft 54, which is rotatably mounted on the kneading base 2. The kneading shaft 54 ​​includes a transmission section 541 located in the middle and two inclined sections 542 located at both ends of the transmission section 541. The central axis of the inclined section 542 has a fixed inclination angle with the rotation axis of the transmission section 541, that is, the inclined section 542 is eccentric. The output end of the kneading motor 51 is connected to the transmission section 541 for transmission. The massage arm 53 is rotatably connected to the inclined section 542 through bearings.

[0050] When the kneading motor 51 is working, it drives the kneading shaft 54 ​​to rotate as a whole. Due to the eccentric design of the inclined section 542, the massage arms 53 mounted on it rotate on their own axis while revolving around the central axis, so that the massage arms 53 on both sides simulate the alternating kneading action of swinging and squeezing towards the center.

[0051] The massage assembly also includes a tapping shaft 55, which is rotatably connected to the nut seat 4 via a bearing. The tapping shaft 55 includes a middle section 551 and two eccentric sections 552 on both sides. The output end of the tapping motor 52 is connected to the middle section 551. Each eccentric section 552 is rotatably provided with a connector 57. The number of connectors 57 is the same as the number of massage arms 53 and corresponds to the number of massage arms 53. A connecting rod 56 is provided between the connector 57 and the corresponding massage arm 53.

[0052] Specifically, one end of the connecting rod 56 is a ball end, which is movably installed in the spherical connecting hole 58 of the massage arm 53 to form a universal connection; the other end is hinged to the connecting piece 57 on the corresponding eccentric section 552.

[0053] When the tapping motor 52 drives the tapping shaft 55 to rotate, the eccentric section 552 drives the connecting piece 57 to make a circular motion, which in turn pushes the massage arm 53 to reciprocate around the axis of the inclined section 542 of the kneading shaft 54 ​​through the connecting rod 56, thereby realizing the tapping massage action.

[0054] In this embodiment, there are four massage arms 53. Two massage arms 53 are provided on each inclined segment 542. Similarly, two connecting rods 56 are provided on each eccentric segment 552. The spherical connecting holes 58 of the two massage arms 53 on the same inclined segment 542 are located on both sides of the rotating connection, so that the two massage arms 53 on the same inclined segment 542 swing in opposite directions to simulate the alternating action of both hands.

[0055] The lifting base 3 is slidably mounted on the base 1 via a sliding groove structure. Alternatively, other structures can be used to restrict the linear sliding of the lifting base 3 on the base 1.

[0056] The lifting base 3 is provided with a nut seat 4. In this embodiment, the nut seat 4 is slidably disposed relative to the lifting base 3 along the guide rail on the lifting base 3. The lifting base 3 is provided with an adjustment component that drives the nut seat 4 to slide or lock relative to the lifting base 3. The adjustment component includes a transmission shaft 72 rotatably connected to the lifting base 3 and an adjustment motor 71 that drives the transmission shaft 72 to rotate. The transmission method between the output shaft of the adjustment motor 71 and the transmission shaft 72 can be conventional means such as pulleys and gears. The specific configuration can be set according to the space of the massage device, which will not be described in this solution.

[0057] The drive shaft 72 has a threaded section, and the nut seat 4 is fixedly provided with a nut 41 that is threadedly engaged with the threaded section of the drive shaft 72. When the adjusting motor 71 is working, it drives the drive shaft 72 to rotate, which in turn drives the nut 41 and the nut seat 4 to move along the axial direction of the drive shaft 72. At the same time, the axial direction of the drive shaft 72 is parallel to the sliding direction of the lifting base 3 on the base 1.

[0058] The collapse assembly includes an elastic element 6, an upper buckle 31 and a lower buckle 11. In this embodiment, the elastic element 5 is selected as a tension spring, with its two ends connected to the swing ends of the base 1 and the kneading base 2 respectively. Under normal conditions, the elastic element 6 is pre-stretched to provide a pulling force towards the base 1 for the kneading base 2, so as to keep it stable and limit its random swing.

[0059] The upper buckle 31 is fixed or integrally set with the lifting base 3. The upper buckle 31 is provided with a buckle groove 311 with an opening facing the base 1. The lower buckle 11 is fixed or integrally set with the base 1. The bottom of the lower buckle 11 is provided with a guide slope. After the upper buckle 31 passes through the guide slope, it gradually deforms and tilts until the lower buckle 11 enters the buckle groove 311. Then the upper buckle 31 tilts and resets to complete the engagement and locking.

[0060] In the normal locked state, the lower buckle 11 is located in the buckle groove 311 of the upper buckle 31. When the massage arm 53 is pressed, the pressure is transmitted to the tapping shaft 55, causing the tapping shaft 55 to tend to move away from the kneading shaft 54. This causes the side wall of the buckle groove 311 to abut tightly against the wall of the lower buckle 11, thereby mechanically locking the lifting base 3 on the base 1 and preventing it from slipping.

[0061] In addition, the lifting base 3 and the base 1 are respectively provided with a first limit 8 and a second limit 9 that restrict the sliding distance of the nut seat 4. The first limit 8 is closer to the kneading base 2 than the second limit 9. After the nut seat 4 slides relative to the base 1, it abuts against the first limit 8 or the second limit 9.

[0062] Working principle:

[0063] Normal operation and adjustment mode: The upper buckle 31 and the lower buckle 11 are locked together, and the lifting base 3 is fixed.

[0064] When the adjusting motor 71 is not working, the threaded section and the nut 41 are in a self-locking state, and the nut seat 4 and the lifting base 3 are relatively fixed. At this time, the kneading motor 51 and the tapping motor 52 work, respectively driving the massage arm 53 to complete the kneading and tapping actions.

[0065] When the initial tilt angle of the massage arm 53 needs to be adjusted to change the massage intensity, the adjustment motor 71 can be started to drive the transmission shaft 72 to rotate, thereby driving the nut seat 4 to slide relative to the lifting base 3. At this time, the lifting base 3 is stationary due to the locking of the upper buckle 31 and the lower buckle 11, thereby changing the distance between the tapping shaft 55 and the kneading shaft 54. Through the transmission of the connecting rod 56, the massage arm 53 will swing around the kneading shaft 54 ​​at an angle to achieve tilt angle adjustment. The movement range of the nut seat 4 is limited between the first limit 8 and the second limit 9.

[0066] Safety Collapse Mode: When the occupant's body is pressed abnormally and violently against the massage arm 53 due to emergency braking or collision of the vehicle, the pressure acting on the massage arm 53 is transmitted to the kneading base 2 through the kneading shaft 54. When the pressure exceeds the pre-tightening force of the elastic member 6, the swing end of the kneading base 2 is forced to overcome the tension of the elastic member 6 and swing around the first travel axis 12. As a result, the massage arm 53 swings backward with the kneading shaft 54 ​​and actively moves away from the occupant's back.

[0067] During the swinging process, the swinging end of the kneading base 2 squeezes or pushes the adjacent upper buckle 31. The upper buckle 31 has a certain deformation capacity and tilts after being subjected to force, causing the lower buckle 11 to come out of the buckle groove 311, thereby releasing the buckle and unlocking the lifting base 3.

[0068] At the same time, the pressure on the massage arm 53 is applied to the striking shaft 55 through the connecting rod 56, generating a force that pushes the striking shaft 55 away from the kneading shaft 54. Since the adjusting motor 71 is in the locked state at this time, the nut seat 4 and the lifting base 3 are relatively fixed, and the two slide together away from the kneading shaft 54 ​​under the push of the striking shaft 55.

[0069] The sliding action causes the lifting base 3 to move the tapping shaft 55 backward, and pulls the massage arm 53 through the connecting rod 56, so that it swings around the kneading shaft 54 ​​to flatten it, that is, to fit the back of the seat more closely.

[0070] It should be noted that the end point of the collapse stroke is determined by the second limit 9. When the nut seat 4 slides and abuts against the second limit 9 on the base 1, the massage arm 53 has been fully extended and retracted, and is no longer in contact with the occupant's body or only in slight contact, which greatly reduces the risk of impact injury.

[0071] Reset action: After the collapse occurs, the upper latch 31 separates from the lower latch 11, and the nut seat 4 abuts against the second limit 9;

[0072] Start the adjustment motor 71 to drive the transmission shaft 72 to rotate. Since the nut seat 4 is blocked by the second limit 9 and cannot move further, according to the principle of thread transmission, the rotating transmission shaft 72 will drive itself and the lifting base 3 fixed to it to move towards the kneading shaft 54.

[0073] The lifting base 3 moves forward, causing the upper buckle 31 on it to gradually approach the fixed lower buckle 11. When the lower buckle 11 contacts the guide slope of the upper buckle 31, it will force the upper buckle 31, which has been elastically reset, to undergo slight deformation until the lower buckle 11 clicks and slides back into the buckle groove 311, completing the automatic fastening and locking.

[0074] At this point, the lifting base 3 is locked again, and the nut seat 4 can move relative to the lifting base 3 to the first limit 8 under the continued drive of the adjusting motor 71, and the device is completely restored to its initial working state.
