Specific implementation mode
Below in conjunction with drawings and the specific embodiments, the present invention will be described in detail.
Embodiment 1.
As shown in figures 1-8, the present embodiment provides a kind of anti-rotation structures for electronic parking clamp, including screw rod 1 and spiral shell
Set 2,2 inner wall of the swivel nut are provided with driving internal thread 21, are provided on the screw rod 1 and driving 21 threaded engagement of internal thread
External screw thread 11 is driven, further includes for carrying out the fixed anti-turn screw 3 of anti-rotation to swivel nut 2,2 end set of the swivel nut has and prevents
Turn the anti-rotation groove 23 of 3 inlay card of screw cooperation.
It is the configuration of the present invention is simple, easy for installation, pass through 3 three swivel nut 2, screw rod 1, anti-turn screw mutual edge fits of part, it is real
Show anti-rotating function, increased anti-torque, reduces the tired loosening problem caused by part moves repeatedly, while also reducing
Because of 1 overexercise of screw rod, the problem of leading to failure mechanisms, the anti-torque of bigger can be provided, while can solve because of zero
Part tired loosening problem, anti-turn screw 3 caused by moving repeatedly can also coordinate with the stop notch on parking screw rod 1, prevent
Because of 1 overexercise of anti-rotation parking screw rod, and the problem of lead to failure mechanisms.
Wherein, the middle part of the anti-turn screw 3 is provided with anti-rotation step 31, and head is provided with stopping step 32, is combining
Under state, the anti-rotation step 31 is embedded in anti-rotation groove 23, prevents swivel nut 2 from rotating.Anti-rotation groove 23 is preferably half round cut,
Under assembled state, match with the anti-rotation step 31 of anti-turn screw 3.
Further, 11 end set of driving external screw thread of the screw rod 1 has stop notch 12, when stop notch 12 rotates
Clamping both when to 32 position of stopping step prevents screw rod 1 from being rotated further, can effectively prevent screw rod 1 rotate excessively abjection with
The cooperation of 2 screw thread of swivel nut.
Further, 3 head of the anti-turn screw is provided with interior spanner bayonet 33, preferably die nut bayonet, can be more
Well, anti-turn screw 3 is more easily tightened.
Wherein, 2 outer wall of the swivel nut is provided with the fixation external screw thread 22 being connect for the inlay card body with electronic parking clamp,
Swivel nut 2 can be preferably fastened, anti-torque is increased, which can also consolidate swivel nut 2 in combination with fastening glue
It is fixed.
Preferably, the quantity of the anti-rotation groove 23 is two, it is symmetricly set on the both sides of 2 end of swivel nut.
The anti-rotation structure for electronic parking clamp of the present invention, passes through 3 three swivel nut 2, screw rod 1, anti-turn screw parts
Mutual edge fit realizes following two anti-rotating function：
One, the anti-rotation of parking swivel nut 2.Only fixed in parking swivel nut 2, parking screw rod 1 is braking and is braking
Stroke and active force when releasing reliably could be played and be controlled, and it is a common perseveration to brake and release,
Also very high, of the invention parking swivel nut 2 is required to connect anti-rotation using mechanical edge fit with anti-turn screw 3 fatigue of part, it is resistance to
It is reliable long.
Two, the movement stop of parking screw rod 1.Parking screw rod 1 withstands brake block in direction of advance, is not in excessive fortune
It is dynamic, but when unclamping, be threadedly coupled if being possible to operate excessively abjection there is no limit if.The present invention is in 1 threaded end of screw rod
On machined a simple anti-rotation seam allowance, rise to 3 position of anti-turn screw in seam allowance, with 3 big boss edge of anti-turn screw interfere,
Rotary motion is limited, and is prevented because of the problem of 1 overexercise of anti-rotation parking screw rod is deviate from from swivel nut 2.
Working principle of the present invention is as follows：
Screw rod 1 generates rotation under the forward drive of motor gear module 4, and swivel nut 2, swivel nut 2 are transmitted to by screw thread spoke
On have anti-rotation groove 23, match with the anti-rotation step 31 of the anti-turn screw 3 on side, so that swivel nut 2 is fixed on caliper body 5,
Operation cannot be rotated, at this moment screw rod 1 is spinned movement with respect to swivel nut 2, and the driving force of motor gear module 4 is converted into screw rod 1
Linear pushing movement, the brake block 6 of brake caliper is withstood on 1 top of screw rod, to realize parking braking.
When parking braking to be released, screw rod 1 is detached from brake block 6 under the reverse drive of motor gear module 4, works as screw rod
When 1 stop notch 12 rises to 32 position of stopping step of anti-turn screw 3, rotary motion is limited, motor gear module 4
Electric current can become larger moment, and the control program of the inside, which is connected to after abnormal current is fed back, can stop motor work, and parking braking is avoided to release
Let off the screw thread range that a screw rod 1 deviates from swivel nut 2.
Those of ordinary skills in the art should understand that：The discussion of any of the above embodiment is exemplary only, not
It is intended to imply that the scope of the present disclosure (including claim) is limited to these examples；Under the thinking of the present invention, above example
Or can also be combined between the technical characteristic in different embodiments, and there are different aspects present invention as described above
Many other variations, in order to it is concise they do not provided in details.Therefore, all within the spirits and principles of the present invention,
Any omission, modification, equivalent replacement, improvement for being made etc., should all be included in the protection scope of the present invention.
