[0001] This utility model relates to the field of automotive seat technology, and in particular to a foot massage system suitable for second-row passengers that is arranged in the back of an automotive seat. Background Technology
[0002] Currently, the functions of car seats mainly focus on seat adjustment, backrest comfort, and lumbar support in some seats. Although some high-end car seats are equipped with massage functions, most of them are for back and buttock massage, with foot massage devices being relatively rare. Existing foot massage devices are bulky and too large to be easily installed on the back of car seats. Utility Model Content
[0003] In view of the above problems, the purpose of this utility model is to provide a foot massage system arranged in the back of a car seat to provide second-row passengers with a relaxing foot massage experience, thereby fundamentally overcoming the shortcomings of the prior art.
[0004] This utility model provides a foot massage system arranged in the backrest of a car seat, comprising: a foot massage system installed at the bottom of the front seat backrest, the foot massage system comprising: a housing fixing plate fixed to the front seat backrest, an outer shell fixed to the housing fixing plate, a transmission gear set and a worm gear drive motor disposed between the housing fixing plate and the outer shell, and a massage head disposed on the side of the outer shell away from the housing fixing plate. The worm gear drive motor is vertically mounted on the outer shell and arranged parallel to the front seat backrest. The transmission gear set comprises: a massage drive gear, a transmission gear, and an input gear rotatably connected to the outer shell. The input gear meshes with the drive worm of the worm gear drive motor through a worm wheel end, the input gear meshes with the transmission gear through a gear end, the transmission gear meshes with the massage drive gear, the massage drive gear is fixed to the massage head and drives the massage head to rotate, and the worm gear drive motor drives the massage head to reciprocate in both forward and reverse directions.
[0005] As a preferred embodiment of this invention, the outer side of the outer shell is covered with a wear-resistant cloth layer.
[0006] As a preferred embodiment of this invention, a heating pad is provided on the wear-resistant cloth layer.
[0007] As a preferred embodiment of this utility model, the two input end gears are symmetrically arranged on both sides of the worm drive motor and mesh with the drive worm, the two transmission gears mesh with the two input end gears respectively, and the two sets of four massage drive gears mesh with the two transmission gears respectively. The four massage drive gears are provided with connecting rods that pass through the outer shell, and the massage head is fixedly connected to the connecting rods.
[0008] As a preferred embodiment of this invention, the four massage heads are arranged in a rectangular pattern, and each massage head is provided with massage bumps.
[0009] As a preferred embodiment of the present invention, the input end gear includes: a turbine located at the turbine end, a gear located at the gear end, and a concentric shaft that connects the turbine and the gear.
[0010] As a preferred embodiment of this invention, a foot pedal is provided at the bottom of the front seat backrest, and the foot pedal is folded up and installed on the bottom of the front seat backrest to cover the foot massage system.
[0011] The beneficial effects of this utility model are as follows: By arranging the worm gear drive motor parallel to the outer casing and adopting a worm gear transmission structure, the required space is successfully reduced. If this structure is arranged on the back of the front seat, it can be linked with the second-row zero-gravity seats. Combined with the zero-gravity seat massage, passengers can experience a multi-directional massage, effectively improving massage comfort and offering advantages such as good massage effect and high safety.

[0019] See Figure 1-6As shown, this embodiment provides a foot massage system arranged in the backrest of a car seat, including: a foot massage system 2 installed at the bottom of the front seat backrest 1. The foot massage system 2 includes: a housing fixing plate 3 fixed to the front seat backrest 1, a housing body 4 fixed to the housing fixing plate 3, a transmission gear set 5 and a worm gear drive motor 6 disposed between the housing fixing plate 3 and the housing body 4, and a massage head 7 disposed on the side of the housing body 4 away from the housing fixing plate 3. The worm gear drive motor 6 is vertically mounted on the housing body 4 and arranged parallel to the front seat backrest 1, and transmits... The gear set 5 includes: two sets of four massage drive gears 8, two transmission gears 9, and two input gears 10 rotatably connected to the inner side of the outer casing 4. The two input gears 10 mesh with the drive worm 12 of the worm drive motor 6 through their respective worm gears 11. The two input gears 10 mesh with the two transmission gears 9 through their respective gears 13. Each transmission gear 9 meshes with the two massage drive gears 8. The four massage drive gears 8 are fixedly connected to the four massage heads 7 and drive the massage heads 7 to rotate. The worm drive motor 6 drives the massage heads 7 to reciprocate by rotating forward and backward.
[0020] Furthermore, in this embodiment, the outer shell 4 is covered with a wear-resistant cloth layer 14, and a heating pad is provided on the wear-resistant cloth layer 14.
[0021] Furthermore, in this embodiment, the four massage heads 7 are arranged in a rectangular pattern, and massage bumps are provided on the massage heads 7.
