The built-in round angle regulating device for seat of vehicle of the prior art, including shell, the circular tooth disk with internal tooth, disk
Seat, driving structure, are equipped with tooth plate in disc seat, outside tooth plate end i.e. opposite with circular tooth disk be equipped with have in circular tooth disk
The end of the external tooth of tooth cooperation, the internal tooth for the separate circular tooth disk that tooth plate inside coordinates with driving structure is equipped with allocating slot, disc seat
It is interior to be equipped with for tooth plate merging and for the storage tank that tooth plate is moved radially along disc seat, it constitutes and is used between circular tooth disk and disc seat
The inner cavity of accommodating driving structure, driving structure include drive shaft, disc spring, latch segment, and the outer wall of latch segment is equipped with to be coordinated with allocating slot
Pusher dog, drive shaft turns drive latch segment when rotating in one direction, and the pusher dog of latch segment drives the tooth plate edge with allocating slot
Circular tooth disk is moved radially outward, and is locked after the internal tooth cooperation of the external tooth and circular tooth disk of tooth plate, tooth plate drives with circular tooth disk limit
Axis is limited with circular tooth disk, and when drive shaft turns drive latch segment to be rotated towards another opposite direction, the pusher dog of latch segment drives tool
There is the tooth plate of allocating slot to be moved radially inwardly along circular tooth disk, the external tooth of tooth plate and the internal tooth of circular tooth disk are detached from and unlock, tooth plate and circle
Fluted disc does not limit i.e. drive shaft and is not limited with circular tooth disk.
Since recliner size limits, the tooth form of the external tooth of tooth plate and the internal tooth of circular tooth disk also receives limitation, to influence
The keying strength of tooth plate and circular tooth disk locks intensity, and tooth plate with circular tooth disk tooth is only single layer is set in existing conventional design
Meter, is only capable of slightly increasing keying strength from the tooth Shape Design of tooth plate and circular tooth disk, can not make substantial breakthroughs, can not
Meet the locking intensity needs of part high standard.
Invention content
The technical problem to be solved by the present invention is to：A kind of keying strength that can make tooth plate and circular tooth disk is provided to carry at double
High high-strength vehicle seat angle adjustor core members.
Technical solution is used by the present invention solves the above problems：A kind of high-strength vehicle seat angle adjustor core members,
Including circular tooth disk, tooth plate and driving structure, the driving structure coordinates with tooth plate to be locked or be unlocked, and the tooth plate is more
A and be provided at circumferentially spaced along circular tooth disk, the circular tooth disk is equipped with groove, and the recess sidewall is equipped with internal tooth, the tooth plate outer wall
Equipped with the external tooth coordinated with internal tooth, the number of plies of the internal tooth is m layers and along circular tooth disk axial arranging, and the number of plies of the external tooth is n
Layer and internal tooth corresponding with diameter cooperation, wherein m are the integer more than or equal to 2, and n is the integer more than or equal to 1, and m is more than
Equal to n.
Compared with the prior art, the advantages of the present invention are as follows：Sequentially become by the way that multilayer, that is, m layers of diameter is arranged in circular tooth disk

Integer, n is the integer more than or equal to 1, and m is more than or equal to n, and under normal circumstances, m and n are respectively less than 10.
Wherein, the structure of storage tank 3.1 herein can also be that multiple convex blocks 3.4, phase is arranged in the end face of disc seat 3
Storage tank 3.1 is constituted between adjacent convex block 3.4.
Wherein, 2 quantity of tooth plate is multiple, generally 2~10, and the circumferential direction along the drive shaft 4.1 of driving structure 4 is uniform
It is intervally arranged.
Wherein, the number of plies of the internal tooth 1.2 of circular tooth disk 1 can be the multilayer consistent with 2.1 number of plies of external tooth of tooth plate 2, i.e. m=
N can also be, the number of plies, that is, m that the number of plies of internal tooth 1.2 is more than external tooth 2.1 is more than n, n-layer external tooth 2.1 in m layer internal tooth 1.2 directly
The corresponding n-layer therein cooperation of diameter is engaged, and in this way when process circular tooth disk 1, can be processed general in m layers
The circular tooth disk 1 of tooth 1.2, and when selecting tooth plate 2 to be coordinated, the corresponding number of plies can be selected according to the needs of keying strength
Tooth plate 2 to meet different keying strength needs；
Specifically, as shown in figure 4, the number of plies of the internal tooth 1.2 of circular tooth disk 1 is consistent with 2.1 number of plies of external tooth of tooth plate 2 three
Layer structure；
As shown in Fig. 5~7, the number of plies of internal tooth 1.2 is more than the number of plies of external tooth 2.1, and the number of plies of the internal tooth 1.2 of circular tooth disk 1 is
Three layers, including the first endoperistome 1.2.1, the second endoperistome 1.2.2, third endoperistome 1.2.3 that diameter sequentially reduces, external tooth
2.1 number of plies is two layers, wherein as shown in figure 5, the external tooth 2.1 of tooth plate 2 includes the first exoperistome 2.1.1, the second exoperistome
