[0029] The accompanying drawings Figures 1-7 A planar tooth type mechanical lock structure, comprising an armature 1 and a lock plate 2, the armature 1 and the lock plate 2 are designed in a bite type, the armature 1 is installed on the motor shell, the lock plate 2 is fixedly matched with the motor shaft, and the lock plate 2 is installed on one side of the outer surface of the armature 1 installed on the motor.
[0030] The armature 1 and the lock plate 2 are both provided with annular locking structures, the centers of the annular locking structures on the armature 1 and the lock plate 2 are coaxial with the geometric centers of the armature 1 and the lock plate 2, and the annular locking structures of the armature 1 and the lock plate 2 are correspondingly arranged in structure and size.
[0031] The annular locking structures of the armature 1 and the lock plate 2 are misaligned and bite each other, so that the armature 1 and the lock plate 2 form a lock structure.
[0032] The annular locking structure on the armature 1 is composed of a plurality of armature teeth 12 and a plurality of armature grooves 11 arranged alternately to form a ring connected at the head and tail, the armature teeth 12 protrude from the surface of the armature 1, the armature grooves 11 are recessed in the armature 1, and the armature teeth 12 and the armature grooves 11 are arranged alternately, so that the side surfaces of the armature teeth 12 and the armature grooves 11 are used for surface contact, thereby playing a locking role.
[0033] The annular locking structure on the lock plate 2 is composed of a plurality of lock plate teeth 21 and a plurality of lock plate grooves 22 arranged alternately to form a ring connected at the head and tail, the lock plate teeth 21 protrude from the surface of the lock plate 1, the lock plate grooves 22 are recessed in the lock plate 1, and the lock plate teeth 21 and the lock plate grooves 22 are arranged alternately, so that the side surfaces of the lock plate teeth 21 and the lock plate grooves 22 are used for surface contact, thereby playing a locking role.
[0034] When the armature 1 and the lock plate 2 are assembled in a bite type, the armature teeth 12 are inserted into the lock plate grooves 22, and the lock plate teeth 21 are inserted into the armature grooves 11, so that all the armature teeth 12 in the annular locking structure of the armature 1 are inserted into the lock plate grooves 22 of the annular locking structure of the lock plate 2, and all the lock plate teeth 21 in the annular locking structure of the lock plate 2 are inserted into the armature grooves 11 in the annular locking structure of the armature 1.
[0035] The armature teeth 12 and the lock plate teeth 21 of the annular locking structures of the armature 1 and the lock plate 2 are both circumferential square teeth.
[0036] The side surfaces of the armature teeth 12 and the armature grooves 11 in the annular locking structure of the armature 1 are both arranged perpendicularly to the surface of the armature 1, the side surfaces of adjacent armature teeth 12 and armature grooves 11 are parallel, the side surfaces of the lock plate teeth 21 and the lock plate grooves 22 in the annular locking structure of the lock plate 2 are both arranged perpendicularly to the surface of the lock plate 21, and the side surfaces of adjacent lock plate teeth 21 and lock plate grooves 22 are parallel.
[0037] When the armature 1 and the locking plate 2 are engaged, the side surfaces of the plurality of armature teeth 12 and the plurality of armature grooves 11 on both sides correspond to the side surfaces of the plurality of locking plate teeth 21 and the plurality of locking plate grooves 22 on both sides, respectively, and fully abut as locking surfaces to play a locking function.
[0038] The armature teeth 12 and the armature grooves 11 are arranged in the same angle but different widths, preferably in the arrangement mode that the armature teeth 12 are narrow in size and the armature grooves 11 are wide in size
[0039] The locking plate teeth 21 and the locking plate grooves 22 are arranged correspondingly to the armature grooves 11 and the armature teeth 12, and the locking plate teeth 21 and the locking plate grooves 22 also adopt the arrangement mode that the angle is the same but the width is different, preferably in the arrangement mode that the locking plate teeth 21 are wide in size and the locking plate grooves 22 are narrow in size.
[0040] The tooth width and groove width of the locking plate teeth 21 and the locking plate grooves 22 and the armature grooves 11 and the armature teeth 12 can be changed according to design requirements to reduce the rotation angle.
[0041] When the motor needs to be locked, the armature 1 and the locking plate 2 are attracted when the armature 1 and the locking plate 2 are engaged, the locking plate 2 only needs to rotate an angle of a locking plate tooth 21, and the armature 1 and the locking plate 2 can reach the engaged state, so as to lock the locking plate 2 through the fixed armature 1, and the locking plate 2 further locks the motor shaft.
[0042] After the armature 1 and the locking plate 2 are engaged and locked, the locking surfaces of the armature 1 and the locking plate 2 are in surface contact instead of point or line contact, because the locking surfaces of the armature 1 and the locking plate 2 are multiple, and because the side surfaces of the plurality of armature teeth 12 and the plurality of armature grooves 11 and the plurality of locking plate teeth 21 and the plurality of locking plate grooves 22 are arranged perpendicularly to the surfaces of the armature 1 and the locking plate 2, the armature 1 and the locking plate 2 with the surface contact have a huge locking torque.
[0043] The locking plate 2 is a whole circle structure, the locking structure of the locking plate 2 is annular, and the locking surface is perpendicular to the surface of the locking plate 2 and is in multiple surface contact at the same time, and the locking plate 2 is not easy to warp due to continuous and uniform stress.
[0044] In other embodiments, the side surfaces of the plurality of armature teeth 12 and the plurality of locking plate teeth 21 can be arranged obliquely, and an included angle is arranged between the side surfaces of the plurality of armature teeth 12 and the plurality of locking plate teeth 21 on both sides, and the included angle is preferably 90 or 60 degrees, when the plurality of armature teeth 12 and the plurality of locking plate teeth 21 are oblique tooth structures with the included angle, the plurality of armature teeth 12 and the plurality of locking plate teeth 21 are directly mismatched with the shell, the plurality of armature teeth 12 and the plurality of locking plate teeth 21 are not divided into tooth and groove structures, but are divided into tooth peak and tooth valley structures, that is, when the armature 1 and the locking plate 2 are engaged, the tooth peaks of the plurality of armature teeth 12 are mismatched and inserted into the tooth valleys of the plurality of adjacent locking plate teeth 2 to form stable engagement.
[0045] The several armature teeth 12 and the several locking piece teeth 21 are arranged on the inclined sides, and when the armature 1 and the locking piece 2 are engaged, the gap between the armature 1 and the locking piece 2 is smaller, and the problem of the depth gap of the several armature teeth 12 and the several armature grooves 11 and the several locking piece teeth 21 and the several locking piece grooves 22 when locking can be solved.
[0046] However, since the two sides of the several armature teeth 12 and the several armature grooves 11 and the several locking piece teeth 21 and the several locking piece grooves 22 are arranged in an inclined manner, a tangential force is generated when they are engaged, so that the several armature teeth 12 and the several armature grooves 11 and the several locking piece teeth 21 and the several locking piece grooves 22 can bear smaller force, and are suitable for smaller power motors.
[0047] The locking piece 2 is fixedly connected with the motor shaft, the center position of the locking piece 2 is arranged to be deviated from the hole 4, the motor shaft is inserted into the hole 4, so that the motor shaft and the locking piece 2 rotate synchronously, and in other embodiments, the motor shaft and the locking piece 2 can also be directly fastened by screws on the side to prevent rotation.
[0048] The armature 1 is uniformly distributed with the several limiting grooves 3, the limiting grooves are used for fixing the armature 1 on the motor shell, and when the armature and the locking piece 2 are adsorbed, the locking force of the motor shaft can be borne.
[0049] The above-described embodiments only express several embodiments of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
