Specific embodiment
The utility model is described in detail below in conjunction with drawings and the specific embodiments.
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 swivel nut are provided with driving internal screw thread 21, are provided on the screw rod 1 and driving 21 threaded engagement of internal screw 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 of swivel nut is provided with and prevents
Turn the anti-rotation groove 23 of 3 inlay card of screw cooperation.
The utility model structure is simple, easy for installation, passes through 3 three swivel nut 2, screw rod 1, anti-turn screw part phase mutual connections
Side realizes anti-rotating function, increases anti-torque, reduces tired loosening problem caused by moving repeatedly because of part, simultaneously
The problem of also reducing because of 1 overexercise of screw rod, leading to failure mechanisms can provide bigger anti-torque, while can solve
Tired loosening problem, anti-turn screw 3 caused by certainly moving repeatedly because of part can also match with the stop notch on parking screw rod 1
The problem of closing, preventing because of 1 overexercise of anti-rotation parking screw rod, and 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 of driving external screw thread of the screw rod 1 is provided with stop notch 12, when stop notch 12 rotates
Clamping both when to 32 position of stopping step prevents continuing to rotate for screw rod 1, can effectively prevent screw rod 1 rotate excessively abjection with
The cooperation of 2 screw thread of swivel nut.
Further, 3 head of 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 swivel nut is provided with the fixation external screw thread 22 connecting 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 two sides of 2 end of swivel nut.
The anti-rotation structure for electronic parking clamp of the utility model passes through swivel nut 2, screw rod 1, anti-turn screw 3 three
The mutual edge fit of part, realizes following two anti-rotating function:
One, the anti-rotation of parking swivel nut 2.Only in the case where parking swivel nut 2 is fixed, parking screw rod 1 is braking and is braking
Stroke and active force when releasing reliably could be played and be controlled, and braking and releasing is a common perseveration,
Also very high to the fatigue requirement of part, the parking swivel nut 2 of the utility model is connected with anti-turn screw 3 using mechanical edge fit anti-
Turn, it is durable reliable.
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, it is threadedly coupled if being possible to operate excessively abjection there is no limit if.The utility model is in 1 screw thread of screw rod
It machined a simple anti-rotation seam allowance on end, rise to 3 position of anti-turn screw in seam allowance, with the big boss edge of anti-turn screw 3
Interference, rotary motion are limited, and are prevented because of the problem of 1 overexercise of anti-rotation parking screw rod is deviate from from swivel nut 2.
The working principle of the utility model is as follows:
Screw rod 1 generates rotation under the forward driving of motor gear module 4, is transmitted to swivel nut 2, swivel nut 2 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,
It is not able to rotate operation, 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 being driven in the reverse direction 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 can stop motor work after being connected to abnormal current feedback, and parking braking is avoided to release
Let off the screw thread range that a screw rod 1 deviates from swivel nut 2.
It should be understood by those ordinary skilled in the art 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 utility model, the above reality
Applying can also be combined between the technical characteristic in example or different embodiments, and there are the utility model as described above
Many other variations of different aspect, for simplicity, they are not provided in details.Therefore, all spirit in the utility model
Within principle, any omission, modification, equivalent replacement, improvement for being made etc. should be included in the protection scope of the utility model
Within.
