Below, in order to avoid the confusion in understanding, the contact rod solved on latch contact 60B is referred to as " unblock contact rod
65B ", the contact rod that lockout contactor is switched on 60A is referred to as " locking contact rod 65A " to illustrate.
Unlock contactless contactor 60B（Or solution lock-switch）60A is switched with lockout contactor（Or locking switch）, it is point
Not with can be with unblock contact rod 65B and locking what the corresponding first protuberance 80B and the second protuberance 80A of contact rod 65A be contacted
Mode a pair of contactless contactors on the printed circuit board 50 arranged apart.
When unblock contactless contactor 60B is contacted with the first protuberance 80B, unblock contact rod 65B is moved, and solves interlocking
Unblock contact rod 65B on tentaculum switch 60B is contacted with contact site 63B；When lockout contactor switchs 60A and the second protuberance
When 80A is contacted, locking contact rod 65A is moved, the locking contact rod 65B and contact site 63A on lockout contactor switch 60A
Contact.
In addition, though being marked not on drawing, unblock contactless contactor 60B and lockout contactor switch 60A can include
When unlocking contact rod 65B or locking contact rod 65A is moved by the first protuberance 80B or the second protuberance 80A respectively,
The elastic support part that the elasticity of opposite direction is supported is provided to unblock contact rod 65B and locking contact rod 65A.
Elastic support part, is provided to unblock contact rod 65B and locking contact rod 65A and contact site 63A, 63B are in opposite direction
Elasticity support, so as to play the effect of the contact force on uniform contact site 63A, 63B.
In addition, the first protuberance 80B and the second protuberance 80A, respectively with unblock contact rod 65B and locking contact rod 65A
The leading section of contact, in the direction of contact, can form inclined-plane in outside.
It can be expressed as in more detail, as shown in Figure 3 and Figure 4, the first protuberance 80B, with can be with being arranged in printed circuit
In the two sides of plate 50, shown in drawing below unblock contactless contactor 60B on the 65B contacts of unblock contact rod mode cloth
Put；Second protuberance 80A, with can with being arranged in the two sides of printed circuit board (PCB) 50, shown in drawing above locking contact
The mode of locking contact rod 65A contacts on device switch 60A is arranged.
Here, the first protuberance 80B effect is, it is logical in bottom when locking Components 70 are moved to the top of drawing
The bottom of the locking bar 30 of the protrusion of lockhole 25 is crossed, then is spun off from locked groove, so as to be unlocked to steering column.Therefore,
One protuberance 80B, can form inclined-plane laterally in the direction contacted with unblock contact rod 65B.That is, the first protuberance
Lower end in 80B leading end portion, figure is close to unblock contact rod 65B, and for lower end, upper end can be allowed to beveling
Separated with unblock contact rod 65B.
In addition, the second protuberance 80A effect is, when locking Components 70 are moved to the bottom of drawing, in lockhole
The bottom of locking bar 30 inside 25, is protruded by lockhole 25, and inserts locked groove, so as to lock steering column.Therefore, connect with locking
The leading end portion of rod 65A contacts is touched, in the direction of contact, inclined-plane can be formed laterally.That is, the second protuberance 80A
Upper end in leading end portion, figure is close to locking contact rod 65A, and for upper end, lower end can be allowed to and locked with beveling
Contact rod 65A is separated.
First protuberance 80B and the second protuberance 80A leading end portion can be with roundings.As the first protuberance 80B and second
When protuberance 80A leading end portion is made rounding, it has easily design unblock contact rod 65B and locking contact rod 65A with contacting
Time portion 63A, 63B required when contacting and the advantage of contact force.
In addition, the first protuberance 80B and the second protuberance 80A, is starting inclined part, i.e. the first protuberance 80B's
Upper end and the second protuberance 80A lower end and the part for tilting end, i.e. the first protuberance 80B lower end and the second protuberance
80A upper end, unblock contact rod 65B and locking contact rod 65A are preferably at least made respectively to be moved to contact portion 63A, 63B
The inclined-plane for the angle moved and contacted.
It can be expressed as in more detail, the left and right spacing distance of the first protuberance 80B top and bottom on drawing, such as
, at least should be bigger than unblock contact rod 65B and locking contact rod 65A displacement D shown in Fig. 3 and Fig. 4.
The startup of the preferred embodiment for the automobile electric power steering (EPS) device of the invention being now constructed as above
Journey, 3 and Fig. 4, is described in detail as follows referring to the drawings：First, as shown in figure 3, in order to which locking bar 30 is inserted into locked groove, on drawing
When lower section is moved, the leading end portion of the second protuberance 80A on stopper Components 70 switchs mobile lockout contactor on 60A
Contact rod 65A is locked, is allowed to contact with contact site 63A.When in this way, locking contact rod 65A is opened with lockout contactor
When closing 60A contact site 63A contacts, the locked electric signal of steering column is sent to control unit, control unit drives according to signal, limitation
The action of dynamic portion's assembly 40, or chain control other functions operating member.
Secondly, as shown in figure 4, in order that locking bar 30 spins off from locked groove, when being moved to the top on drawing, stopper
The leading end portion of the first protuberance 80B on Components 70, while movement to direction above printed circuit board (PCB) 50, mobile unblock
Unblock contact rod 65B on contactless contactor 60B, is allowed to contact with contact site 63B.When unblock contact rod 65B is contacted with unblock
During device switch 60B contact site 63B contacts, the locked electric signal of steering column is sent to control unit, control unit then according to signal,
Control the action of drive division assembly 40, or chain control other functions operating member.
As described above, according to the present invention automobile electric power steering (EPS) device preferred embodiment, compared with prior art,
It has prevented the influence of surrounding magnetic field caused by electronic unit from source, physically can sense steering column without any mistake
Locking and unblock more than 30,000 times, therefore the durability and reliability of product can be improved.
In addition, according to the preferred embodiment of the automobile electric power steering (EPS) device 1 of the present invention, unblock contactless contactor 60B
The specified portions of printed circuit board (PCB) 50 can be welded on lockout contactor switch 60A, with assembling process can be simplified, significantly
Degree reduces the advantage of installation time.
Except exception is preferable to carry out, the present invention can also have other embodiment, all use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within scope of the present invention.
