The knocking box 320 is also internally provided with a return spring 326, one end of the return spring 326 is fixedly connected to the bottom of the knocking box body 321, the other end of the return spring 326 is fixedly connected with a power rod 331, and particularly is connected to the power rod 331 at a position between a second support 325 and an electric telescopic rod 332, so that the knocking hammer 330 can realize reciprocating motion along the axial direction of the knocking hammer, and continuous knocking massage can be realized.

The control panel 11 is electrically connected with the steering motor 313, the electric telescopic rod 332 and the knocking motor 324, and the control panel 11 can control the starting and stopping of the steering motor 313, the electric telescopic rod 332 and the knocking motor 324.

The use of the striking mechanism 300 is described in detail below: when a driver needs to massage the shoulders, the steering motor 313 is started through the control panel 11 to drive the driving gear 314 to rotate, and the driving gear 314 drives the driven gear 312 to rotate so as to drive the steering rod 311 to rotate, and further drive the knocking box 320 to rotate. The position of the hammer body 334 is adjusted by controlling the electric telescopic rod 332 to stretch and retract through the control panel 11, then the knocking motor 324 is started to work through the control panel 11, the knocking motor 324 drives the cam 323 to rotate, the cam 323 presses the driven piece 3311 at one end of the power rod 331 down, the knocking hammer 330 rises upwards, when the cam 323 is separated from the driven piece 3311, the power rod 331 is reset under the action of the reset spring 326, and the knocking hammer 330 knocks downwards to realize the relaxing and massaging of the shoulder.

In this application, through setting up knocking mechanism 300, control knocks hammer 330 work, is convenient for strike the massage to the shoulder, alleviates the ache that long-time driving caused, has reduced the incidence of relevant occupational disease, has increased car seat 1000's multifunctionality, has improved car seat 1000's comfort level.

The above description explains the specific structure of the massage mechanism 100 and the knocking mechanism 300 when the backrest body is adjusted to the vertical position, and does not affect the structural relationship and the working process between the massage mechanism 100 and the knocking mechanism 300 and the backrest body when the backrest body is adjusted to other angles.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
