[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0031] like Figures 1 to 7 As shown, the vehicle seat back 100 of the embodiment of the utility model includes a backrest body 1 and a massage component 2, the massage component 2 includes a massage ball 21, a driving member 22 and an elastic member 23, the massage ball 21 is rotatably connected to the backrest body 1, the driving member 22 is connected to the backrest body 1, and the two ends of the elastic member 23 are respectively connected to the driving member 22 and the massage ball 21.

[0032] The vehicle seat backrest 100 of the embodiment of the utility model is configured such that the massage ball 21 is rotatably connected to the backrest body 1, the driving member 22 is connected to the backrest body 1, and the two ends of the elastic member 23 are respectively connected to the driving member 22 and the massage ball 21, so that the driving member 22 can drive the massage ball 21 to rotate through the elastic member 23, thereby achieving massage for the user. In addition, the driving member drives the massage ball 21 to rotate through the elastic member 23, so that when the user leans on the massage ball 21 for massage, there is elastic contact between the massage ball 21 and the user, so that the position and state of the massage ball 21 can be adaptively adjusted according to the user's body shape and the leaning position, so that the massage ball 21 fits well with the user, improving the user's massage experience.

[0033] In some embodiments, Figures 1 to 5 As shown, the massage assembly 2 further includes a base 27 , the driving member 22 is connected to the base 27 , and the base 27 is connected to the backrest body 1 .

[0034] By connecting the driving member 22 to the base 27, and using the base 27 to connect to the backrest frame 11, when assembling the vehicle seat back 100, the massage ball 21, the driving member 22, the elastic member 23 and the base 27 can be assembled first to realize the assembly of the massage component 2, and then the massage component 2 is connected to the backrest body through the base 27. The assembly of the vehicle seat back 100 is convenient.

[0035] Optionally, the backrest body 1 has a mounting cavity 111 and a through hole 121 connected to the mounting cavity 111, and the through hole 121 is for the massage ball 21 to pass through. The base 27 is movably arranged in the mounting cavity 111 along the thickness direction of the backrest body 1. The vehicle seat back 100 also includes an adjustment component, which is arranged in the mounting cavity 111 and connected to the massage component 2, and the adjustment component is used to drive the massage component 2 to move along the thickness direction of the backrest body 1. Among them, the adjustment component may include a telescopic rod and a drive motor, and the drive motor is used to drive the telescopic rod to extend and retract, thereby driving the massage component 2 to move along the thickness direction of the backrest body 1.

[0036] For example, Figures 1 to 3As shown, the backrest body 1 includes a backrest frame 11 and a backrest pad 12, the backrest frame 11 has an installation cavity 111, and the backrest pad 12 has a through hole 121 connected to the installation cavity 111. The base 27 is movably connected to the backrest frame 11 along the thickness direction of the backrest body 1. Among them, the thickness direction of the backrest body 1 can be understood as: the front and back direction of the backrest body 1. When the user needs to use the massage component 2 for massage, the massage component 2 is driven to move forward by the adjustment component so that the massage ball 21 passes through the through hole 121. At this time, the user can contact the massage ball 21 and use the massage component 2 to achieve massage; when the massage component 2 is not needed, the massage component 2 is driven to move backward by the adjustment component so that the massage ball 21 passes into the through hole 121. At this time, the massage ball 21 will not protrude from the surface of the backrest body 1, avoiding the massage ball 21 affecting the user's normal leaning on the backrest body 1.

[0037] By movably arranging the base 27 in the mounting cavity 111 along the thickness direction of the backrest body 1, different needs of users can be better met and the user experience can be further improved.

[0038] In some embodiments, Figure 3 As shown, the backrest body 1 includes a shoulder support portion 13 for the user's shoulder 10 to lean against, and the massage component 2 is disposed on the shoulder support portion 13 .

[0039] At present, most users have the problem of neck and shoulder discomfort. By arranging the massage component 2 on the shoulder support part 13, the massage component 2 can be used to perform a massage operation on the user's shoulder 10, thereby better meeting the user's needs and improving the user's massage experience.

[0040] In some embodiments, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, there are multiple massage balls 21 , which are divided into multiple massage groups. Each massage group includes at least one massage ball 21 . The multiple massage groups are arranged at intervals along the width direction of the backrest body 1 .

[0041] For example, Figure 4 As shown, the number of massage balls 21 is six, and the six massage balls 21 are divided into two massage groups, and each massage group includes three massage balls 21 .

[0042] By providing a plurality of massage balls 21, and dividing the plurality of massage balls 21 into a plurality of massage groups, the plurality of massage groups are arranged at intervals along the width direction of the backrest body 1, so that each massage group can massage different parts of the user, and thus the massage component 2 can be used to massage multiple different parts of the user, further improving the user's massage experience.

[0043] Alternatively, if Figure 4 and Figure 5 As shown, the massage group includes at least two massage balls 21, and the massage assembly 2 also includes a plurality of connecting plates 24, and the plurality of connecting plates 24 correspond to the plurality of massage groups one by one. There are a plurality of elastic members 23, and the plurality of elastic members 23 correspond to the plurality of connecting plates 24 one by one. The massage balls 21 in each massage group are connected to the corresponding elastic members 23 through the corresponding connecting plates 24.

[0044] Thus, multiple massage balls 21 in a massage group can be connected to the same elastic member 23 via a connecting plate 24, and then the same elastic member 23 can be used to drive the multiple massage balls 21 to rotate, which is beneficial to simplify the structure of the massage component 2, thereby helping to simplify the structure of the vehicle seat back 100 and reduce the cost of the vehicle seat back 100.

[0045] Optionally, multiple elastic members 23 are arranged on both sides of the driving member 22 in the width direction of the backrest body 1, and the driving member 22 includes two output shafts arranged relatively along the width direction of the backrest body 1, and each output shaft is connected to the elastic member 23 arranged on the same side of the driving member 22 in the width direction of the backrest body 1.

[0046] The width direction of the backrest body 1 can be understood as the left-right direction of the backrest body 1. The driving member 22 can be a dual-axis motor. For example, two elastic members 23 are arranged on both sides of the driving member 22 in the left-right direction, and two output shafts of the driving member 22 are arranged relatively along the left-right direction. The output shaft arranged on the left side is connected to the elastic member 23 arranged on the left side, so that the output shaft drives the elastic member 23 arranged on the left side to rotate, thereby driving the massage ball 21 connected to the elastic member 23 arranged on the left side to rotate; the output shaft arranged on the right side is connected to the elastic member 23 arranged on the right side, so that the output shaft drives the elastic member 23 arranged on the right side to rotate, thereby driving the massage ball 21 connected to the elastic member 23 arranged on the right side to rotate.

[0047] Through the above-mentioned design of the driving member 22 and the elastic member 23 , all the massage balls 21 can be driven to rotate simultaneously by one driving member 22 , which is beneficial to further simplify the structure of the massage assembly 2 and reduce the cost of the vehicle seat back 100 .

[0048] Alternatively, if Figure 5 and Figure 6 As shown, the elastic member 23 is a compression spring.

[0049] By configuring the elastic member 23 as a compression spring, the service life of the elastic member 23 is extended, the reliability of the massage assembly 2 is improved, and thus the reliability of the vehicle seat back 100 is improved.

[0050] Alternatively, if Figure 6 and Figure 7As shown, the massage assembly 2 further includes a transmission assembly, through which the elastic member 23 is connected to the driving member 22. The transmission assembly further includes a first transmission member 25 and a second transmission member 26, and the first transmission member 25 is meshed with the second transmission member 26.

[0051] For example, when the massage component 2 is working, the driving member 22 is used to drive the first transmission member 25 to rotate, the first transmission member 25 is used to drive the second transmission member 26 to rotate, and the second transmission member 26 drives the massage ball 21 to rotate through the elastic member 23.

[0052] By providing the first transmission member 25 and the second transmission member 26 , it is convenient to reasonably arrange the position of the driving member 22 according to the specific structure of the backrest body 1 , so as to improve the compactness of the massage component 2 and reduce the space occupied by the massage component 2 in the backrest body 1 .

[0053] The vehicle seat back 100 of the embodiment of the utility model has the following advantages:

[0054] Compared with the pneumatic massage joint, the rotatable massage ball 21 is used to massage the user, so that the massage force is stronger. The structure of the massage ball 21 can simulate the human hand to bring a more intuitive massage effect.

[0055] The massage ball 21 is connected to the driving member 22 by an elastic member 23, so that the massage ball 21 can be adaptively adjusted according to the pressure and posture of the user, giving the user a more comfortable massage experience;

[0056] The setting of the adjustment component allows the massage ball 21 to touch the human body for massage when the user needs massage, and can be retracted when the massage function is not in use, without affecting normal riding.

[0057] The vehicle seat of the embodiment of the utility model comprises the vehicle seat backrest 100 described in any of the above embodiments. The vehicle seat further comprises a seat plate, and the vehicle seat backrest 100 is connected to the seat plate.

[0058] Since the vehicle seat backrest 100 of the embodiment of the present invention improves the user's massage experience, the vehicle seat of the embodiment of the present invention has the advantages of good user experience and the like.
