DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0028] The utility model discloses a massage assembly, including a massage module 1, a mounting frame 2 and an elastic element 3. In the utility model, the massage module 1 can be a massage unit with a harder massage head 22, or a massage airbag unit, or other modules that can massage the human body. It should be pointed out that these massage modules 1 belong to the prior art, and their specific structures are not described here.

[0029] A plurality of elastic elements 3 are arranged between the massage module 1 and the mounting frame 2. In this embodiment, four elastic elements 3 are arranged, and are respectively installed at the four corners of the massage module 1. Of course, the elastic elements 3 may also be of other numbers.

[0030] One end of the elastic element 3 is fixedly connected to the massage module 1, and the other end of the elastic element 3 is fixedly connected to the mounting bracket 2. In the present invention, one end of the elastic element 3 is connected to the massage module 1. When the elastic element 3 is placed in a horizontal direction, the massage module 1 is acted upon by gravity, and the elastic element 3 provides a reaction force to the massage module 1, so that the massage module 1 is attached to the elastic element 3. Similarly, the other end of the elastic element 3 is connected to the mounting bracket 2. In the present invention, the elastic element 3 can produce elastic deformation and has a certain amount of compression in its axial direction. The elastic element 3 bears the gravity of the massage module 1, so that the massage module 1 is cantilevered to the side of the mounting bracket 2. Figure 3 As shown in FIG. 1 , the massage module 1 and the mounting frame 2 are arranged side by side. When they are specifically applied to a car seat, the massage module 1 is in front and the mounting frame 2 is in the back.

[0031] In the present utility model, since the massage module 1 is mounted on the mounting frame 2 through the elastic element 3, the massage module 1 is flexibly mounted on the mounting frame 2. When a rear-end collision occurs in a car, the instantaneous impact force will act on the elastic element 3, thereby causing the elastic element 3 to be compressed, causing the energy to decay and playing a buffering role. In addition, the reaction force of the human body to the massage module 1 can also cause the elastic element 3 to deform, so that the massage module 1 moves as a whole toward the mounting frame 2. After the massage module 1 moves backward a predetermined distance, the position where the massage module 1 is arranged on the car seat will not be too protruding relative to its peripheral position. Therefore, the massage module 1 will not excessively press the human body and cause the risk of dislocation at the joints, thereby achieving the purpose of ensuring safety in use.

[0032] In this embodiment, the elastic element 3 is a compression spring. As another embodiment, the elastic element 3 may also be an air bag, silica gel, a disc spring or other structures.

[0033] In this embodiment, as shown in the figure, the massage assembly also includes a first mounting seat 4 and a second mounting seat 5, one end 10 of the compression spring is fixed to the first mounting seat 4, and the other end 11 of the compression spring is fixed to the second mounting seat 5. The first mounting seat 4 is fixedly connected to the massage module 1, and the second mounting seat 5 is fixedly connected to the mounting frame 2. The first mounting seat 4 is locked to the massage module 1 by a first bolt 6, and the second mounting seat 5 is locked to the mounting frame 2 by a second bolt 7. As shown in the figure, the middle part of the first mounting seat 4 and the second mounting seat 5 is provided with a hole for the bolt to pass through along the axial direction thereof, and the first mounting seat 4 and the second mounting seat 5 can be locked to the massage module 1 and the mounting frame 2 respectively by a bolt and nut structure. There is a spacing between the first mounting seat 4 and the second mounting seat 5. Due to the spacing between the two, in specific applications, the part of the compression spring located between the first mounting seat 4 and the second mounting seat 5 can still be compressed to ensure the buffering function of the massage assembly. In specific applications, the first mounting seat 4, the compression spring and the second mounting seat 5 can be pre-assembled to form a modular structure, which can be easily assembled with the massage module 1 and the mounting frame 2.

[0034] Since the compression spring is a spiral columnar structure and the part of the massage module 1 where the first mounting seat 4 is installed is a non-metallic material, the structure of the first mounting seat 4 and the second mounting seat 5 realizes the fixed connection relationship between the compression spring and the massage module 1 and the mounting frame 2 through a conventional fixed connection method. On the other hand, since the compression spring is fixedly installed through the first mounting seat 4 and the second mounting seat 5, there is no need to adopt a guide rod structure. In any state of use, the compression spring, the first mounting seat 4 and the second mounting seat 5 are always located between the massage module 1 and the mounting frame 2, avoiding the danger caused by extending out of the mounting frame 2 as if a guide rod structure is adopted, thereby ensuring safety in use. It should be pointed out that the part of the massage module 1 where the first mounting seat 4 is installed and the mounting frame 2 are made of metal materials, and the structure of the first mounting seat 4 and the second mounting seat 5 may not be adopted. The compression spring can be directly fixedly connected by welding.

[0035] In this embodiment, a first compression spring groove 8 is provided on the side of the first mounting seat 4, and one end 10 of the compression spring is inserted into the first mounting seat 4, and the wire of the one end 10 of the compression spring is embedded in the first compression spring groove 8. As shown in the figure, the first compression spring groove 8 is a groove-shaped structure and is arranged according to the spiral trajectory of the compression spring wire. After the wire of one end 10 of the compression spring is inserted into the first compression spring groove 8, the first mounting seat 4 and the one end 10 of the compression spring are combined together, and the two can withstand tension or pressure in the axial direction without relative movement. Similarly, a second compression spring groove 9 is provided on the side of the second mounting seat 5, and the second mounting seat 5 is inserted into the other end 11 of the compression spring, and the wire of the other end 11 of the compression spring is embedded in the second compression spring groove 9. By adopting this structure, the fixed installation of the spiral structure compression spring is realized, so that the compression spring can still carry the massage module 1 when it is installed in the horizontal direction.

[0036] In this embodiment, a four-bar mechanism 12 is provided on both sides of the mounting frame 2. As shown in the figure, the four-bar mechanism 12 includes a frame rod 13, an upper rocker 14, a lower rocker 15 and a connecting rod 16, which are hinged end to end in sequence. A mounting portion 17 is provided on the frame rod 13 of the four-bar mechanism 12. The frame rod 13 of the four-bar mechanism 12 is fixedly installed. In specific applications, the frame rod 13 is fixed to the backrest of the car seat through the mounting portion 17. The mounting frame 2 is fixedly connected to the connecting rod 16 of the four-bar mechanism 12. The lower rocker 15 of the four-bar mechanism 12 is provided with a motor front shaft 19. The motor front shaft 19 passes through the front end of the screw of the screw motor 18. The motor front shaft 19 and the front end of the screw can rotate relative to each other, and the housing of the screw motor 18 located below the lower rocker 15 is hinged. In specific applications, such as Figure 3 As shown, the screw motor 18 works to extend the screw upward, and the screw pushes the front shaft 19 of the motor. Under the motion characteristics of the four-bar mechanism 12, the lower rocker 15 and the upper rocker 14 both rotate upward, and the connecting rod 16 located between the lower rocker 15 and the upper rocker 14 moves accordingly, so that the height position of the connecting rod 16 becomes higher and the distance between the connecting rod 16 and the frame rod 13 becomes larger. Correspondingly, the massage component also moves, so that the massage module 1 is pushed out from the folded state. In specific applications, the massage module 1 is installed on the car seat. The position of the massage module 1 can be obviously protruded relative to its peripheral position. When a person uses the massage, the back of the human body leans back in a relaxed state. At this time, there is no need to tighten the related muscle groups of the back. The massage module 1 can provide sufficient reaction force to the human body, so that the massage module 1 can massage effectively. When the massage function is not in use, the four-bar mechanism 12 is reset under the drive of the screw motor 18. The position where the massage module 1 is installed on the car seat will not protrude relative to its peripheral position, and the human body will not feel a hard object when leaning on the car seat.

[0037] In this embodiment, the length of the upper rocker 14 of the four-bar mechanism 12 is greater than the length of the lower rocker 15 of the four-bar mechanism 12. Since the lower rocker 15 is relatively short, the stroke required by the screw motor 18 can also be relatively short, and the displacement of the massage component can also be completed quickly. In addition, compared with other four-bar mechanisms 12, the massage component of the four-bar mechanism 12 with the above structure is moved a greater distance relative to the frame rod 13 for the same screw motor 18 stroke.

[0038] In this embodiment, the connecting rod 16 of the four-bar mechanism 12 is bent, and the connecting rod 16 of the four-bar mechanism 12 is bent toward the frame rod 13 of the four-bar mechanism 12. Since the adjacent ends of the lower rocker 15 and the connecting rod 16 form an acute angle, and the adjacent ends of the upper rocker 14 and the connecting rod 16 form an acute angle, it can ensure that the lower rocker 15 as the active member drives the connecting rod 16 and the upper rocker 14 according to a predetermined working mode, and prevent the lower rocker 15 and the connecting rod 16, and the upper rocker 14 and the connecting rod 16 from rotating in the opposite direction, so that the massage component cannot be pushed out or cannot be retracted toward the frame rod 13.

[0039] In this embodiment, the mounting frame 2 includes a main body 20 and a side frame 21, and the side frame 21 extends forward from the bottom surface of the main body 20. With this structure, the overall thickness of the massage assembly is small, and it is easy to be installed on the car seat.

[0040] The utility model also discloses a car massage seat using the above massage assembly, including a backrest frame, a frame rod 13 of a four-bar mechanism 12 is fixedly connected to the backrest frame and the massage module 1 is oriented toward the front of the backrest frame, and a housing of a screw motor 18 is hinged to the backrest frame. It should be noted that when it is installed on the upper part of the backrest frame, it can massage the shoulders of the human body, and when it is installed in other positions, it can massage the corresponding positions.

[0041] The massage assembly can be installed on a leisure sofa or other massage equipment.

[0042] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
