Description

Technical Field

[0001] The invention relates to the technical field of massage equipment, in particular to a collectible safety massage seat for a vehicle. Background Art

[0002] The seats used in cars on the market generally do not have a massage function. Even if the seats have a massage structure, they are mostly airbag type, with low massage intensity and a single massage method. In order to improve the massage intensity, a massage head that can perform a knocking action is installed on the seat, and the knocking action of the massage head is controlled by a motor and a transmission structure. However, although this type of massage structure increases the comfort of the massage, it also increases safety hazards. When a vehicle collides, the human body is subjected to external impact force, and the human body directly acts on the massage head, which can cause damage to the human body. Summary of the invention

[0003] The present invention overcomes the shortcomings of the prior art and provides a collectible vehicle safety massage seat, which can realize the knocking function, does not hurt the human body, and is safer.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a collectible vehicle safety massage seat, including a chair frame, the chair frame including a backrest and a cushion part, a receiving cavity is arranged on the back of the backrest of the chair frame, a massage mechanism is arranged in the receiving cavity, the massage mechanism includes a frame, a knocking arm and a motor device, the frame is fixedly arranged on the backrest of the chair frame, a backrest board adapted to the back of the human body is fixedly arranged on the frame near the backrest of the chair frame, a layer of buffer is arranged between the backrest board and the backrest of the chair frame, the knocking arm is located between the backrest board and the frame, and the knocking arm is hingedly arranged on the frame. The percussion arm is on the frame, massage heads are respectively arranged on both sides of the hinge of the percussion arm, and the backrest plate and the buffer member are respectively provided with through holes for the massage heads to protrude at the massage heads on both sides of the corresponding percussion arm. The motor device is fixedly arranged on the frame, and the motor device drives the percussion arm to swing, so that the massage heads on both sides of the percussion arm can be alternately extended or retracted from the corresponding through holes, respectively, to achieve alternating percussion massage. When the massage head on one side of the percussion arm extends out of the position of the through hole, the massage head is subjected to the action of the external resistance force, and drives the percussion arm to swing, so that the massage heads on both sides of the percussion arm are placed inside the through hole and are in a collection state.

[0005] By adopting the above scheme, the upper and lower position relationship in this article is not limited to the position during actual use. The vehicle seat can be a seat for a car or a train, or a seat on an airplane or a ship. The number of the knocking arms and the number of the massage heads on both sides of the knocking arms can be determined according to actual needs. The motor device drives the knocking arms to swing. It can be that multiple motor devices control the swinging of each knocking arm individually, or that one motor device controls the swinging of each knocking arm at the same time. More than two knocking arms are provided to increase the range of massage. When a person sits on the chair frame, the motor device drives the knocking arms to swing, so that the massage heads on both sides of the knocking arms can be alternately extended from the corresponding through holes respectively, thereby alternately knocking on the back of the human body, thereby realizing the knocking function, and when the massage head on one side of the knocking arm extends out of the through hole, the massage head on the other side of the knocking arm is located in the through hole. On the other hand, the massage heads on both sides of the knocking arm can also be placed inside the through hole and be in a stored state. When the massage head on one side of the knocking arm extends out of the through hole, when the vehicle collides, the human body is subjected to external impact force, and the back of the human body directly acts on the massage head on one side of the knocking arm. The massage head on one side of the knocking arm is subjected to the resistance force of the back of the human body, and the knocking arm will swing, so that the massage heads on both sides of the knocking arm are placed inside the through hole and are in a stored state. The massage heads on both sides of the knocking arm will not cause damage to the human body. The stored state does not necessarily mean that the massage heads are completely stored in the through hole. The ends of the massage heads can also extend out of the through hole for a small distance, as long as the distance is a safe distance and will not cause damage to the human body. The buffer component plays a certain buffering role to prevent the human body from directly leaning against the backrest board, which is safer.

[0006] A further configuration of the present invention is that the massage mechanism also includes an articulated seat, a drive shaft and a push rod, the articulated seat is fixedly arranged on the frame, the knocking arm is hingedly arranged on the articulated seat, the drive shaft is rotatably arranged on the frame and is located next to the articulated seat, the output shaft of the motor device drives the drive shaft to rotate via a belt transmission structure, one end of the push rod is connected to the drive shaft, and the other end of the push rod is hingedly cooperated with the knocking arm, and the drive shaft drives the push rod to move through the eccentric structure, thereby driving the knocking arm to swing.

[0007] By adopting the above scheme, the output shaft of the motor device drives the driving shaft to rotate through the belt transmission structure. Compared with the gear transmission, the belt transmission can slip and play a certain protective role. The driving shaft drives the push rod to move through the eccentric structure, and the push rod can drive the knocking arm to swing. During the swinging process of the knocking arm, the massage heads on both sides of the knocking arm alternately extend out of the through holes. When a person sits on the chair frame, the massage heads can directly knock on the back of the human body to achieve knocking massage. In addition, the layout of each component is reasonable, so that the overall thickness of the massage mechanism is thinner.

[0008] A further configuration of the present invention is that the knocking arm is respectively provided with an upper hinge hole and a lower hinge hole in the height direction of the hinge seat, the upper hinge hole is located above the lower hinge hole, the upper hinge hole of the knocking arm is hingedly matched with the hinge seat, and the lower hinge hole of the knocking arm is hingedly matched with the end of the push rod.

[0009] By adopting the above solution, the positions of the upper hinge hole and the lower hinge hole are reasonably designed, which can prevent the push rod from contacting other parts when performing eccentric movement, and the structure is simple.

[0010] A further configuration of the present invention is that a plurality of lower hinge holes are provided and are spaced apart and distributed along the height direction of the hinge seat.

[0011] By adopting the above solution, the swing amplitude of the knocking arm can be changed by changing the hinge position between the push rod and the knocking arm, thereby adjusting the knocking force. The structure is simple and the design is reasonable.

[0012] A further configuration of the present invention is that the eccentric structure is an eccentric wheel, the eccentric wheel is arranged corresponding to the push rod, the eccentric wheel is circumferentially linked with the drive shaft, the end of the push rod is sleeved on the eccentric wheel, the drive shaft drives the eccentric wheel to make eccentric movement, the eccentric wheel drives the push rod to move, thereby driving the knocking arm to swing.

[0013] By adopting the above scheme, the central axis of the eccentric sleeve is set away from the central axis of the driving shaft, and the push rod is arranged on the eccentric wheel through the bearing sleeve, which will not affect the normal rotation of the eccentric wheel. When the eccentric wheel rotates with the driving shaft, the eccentric wheel can drive the push rod to move. The push rod is hinged with the knocking arm, so the push rod drives the knocking arm to swing. The structure is simple, the transmission is stable, and the design is reasonable.

[0014] A further configuration of the present invention is that at least two striking arms are provided, and the striking arms are spaced apart along the height direction of the chair frame. Two or more articulated seats, push rods and eccentric wheels corresponding to the striking arms are provided respectively, and the height of each articulated seat is adapted to the shape of the backrest plate. Each eccentric wheel is circumferentially linked to the drive shaft, and the drive shaft can drive each striking arm to swing at the same time.

[0015] By adopting the above solution, multiple knocking arms are driven by one driving shaft, which saves space and motor devices and reduces costs. Of course, the multiple knocking arms are not limited to being distributed in a row at intervals, but can also be arranged in multiple rows or symmetrically. Since the backrest board is arranged in a certain arc, in order to meet the massage needs of different positions of the backrest board, the height of each articulated seat is different.

[0016] A further configuration of the present invention is that support rods are symmetrically arranged on the knocking arms, the massage heads are fixed or integrally arranged on the ends of the support rods, and the two support rods are arranged at a V-shaped angle to each other.

[0017] By adopting the above solution, the two support rods are arranged at a V-shaped angle, so that when the knocking arm swings, the two massage heads will alternately extend out of the through holes, and the support rods will not touch the backrest board. The structure is simple and the design is reasonable.

[0018] A further configuration of the present invention is that the buffer member is a sponge, and the thickness of the buffer member is 3-15 cm.

[0019] By adopting the above solution, the thickness of the sponge is selected appropriately, which plays a certain buffering role and prevents the human body from directly leaning against the backrest board. The structure is simple and the design is reasonable.

[0020] A further configuration of the present invention is that the output shaft of the motor device is parallel to the drive shaft, the belt transmission structure includes a belt, a first pulley and a second pulley, the first pulley is synchronously rotated on the output shaft of the motor device, the second pulley is synchronously rotated on the drive shaft, and the first pulley and the second pulley are connected by a belt.

[0021] By adopting the above solution, the first pulley rotates synchronously with the output shaft of the motor device, and the second pulley rotates synchronously with the drive shaft. The diameter of the second pulley is larger than that of the first pulley, which can play a certain deceleration role, has a simple structure and stable transmission.

[0022] The present invention will be further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
