Description

  The present invention relates to an electric parking brake manual release mechanism, and more particularly to an electric parking brake manual release mechanism for manually releasing a braking force of an electric parking brake using a tool.

  When a vehicle equipped with an electric parking brake is used, for example, when the power stored in the battery disappears, the parking brake switch that activates and stops the parking brake, the parking brake actuator that drives the parking brake, etc. There is. If these occur while the braking force is applied to the wheels by the parking brake, it is no longer possible to release the braking force by normal operation of the electric parking brake. For this reason, the electric parking brake is generally provided so that the braking force can be manually released using a tool. At this time, since the electric parking brake can be released in the absence of the driver, the wheels need to be fastened. For this reason, for example, a technique has been proposed in which a warning is issued to the driver when the side brake is applied, and the warning is stopped when the vehicle stop stored in the vehicle is taken out (see, for example, Patent Document 1). Moreover, the technique which provides a tool storage part in a wheel stop is proposed (for example, refer patent document 2).

(First embodiment)
FIG. 1A is a perspective view showing an electric parking brake manual release mechanism 10 according to the first embodiment, and FIG. 1B is an electric parking brake manual release mechanism from the viewpoint P of FIG. FIG.

  The electric parking brake manual release mechanism 10 includes a sealing member 12, a screw 14, a ring stopper 16, a first plate 18, and a second plate 20. The sealing member 12 is formed in a plate shape, and is fixed to the vehicle body by a screw 14 at a position where the opening of the tool insertion path X is sealed so that the tool cannot be inserted into the tool insertion path X.

  Generally, the electric parking brake is provided so that the braking force can be manually released using a tool. At this time, since the electric parking brake can be released in the absence of the driver, the wheels need to be fastened. However, if it is possible to insert the tool into the tool insertion path where the tool is inserted in order to release the braking force of the electric parking brake without removing the ring retainer, the ring retainer should be disposed under the wheel. There is a risk that the braking force by the electric parking brake may be released.

  For this reason, the electric parking brake manual release mechanism 10 has a ring retaining attachment mechanism 17. The wheel retainer attaching mechanism 17 attaches the wheel retainer to the vehicle so as to prevent the tool from being inserted into the tool insertion path X where the tool is inserted in order to release the braking force of the electric parking brake. The loop retaining attachment mechanism 17 includes a first plate 18 and a second plate 20. The first plate 18 and the second plate 20 place and fix the loop stopper 16 at a position where the insertion of the tool into the tool insertion path X is prevented.

  The ring stopper 16 is formed by bending a plate-like member into a U shape. Each wheel ring 16 has a flat wheel receiving portion 16a, a first vertical portion 16b, and a second vertical portion 16c. The 1st vertical part 16b and the 2nd vertical part 16c become a folding | turning part of a plate-shaped member, and the wheel receiving part 16a is provided between the 1st vertical part 16b and the 2nd vertical part 16c. The first vertical portion 16b is formed longer than the second vertical portion 16c so that the wheel receiving portion 16a becomes an inclined surface when the ends of the first vertical portion 16b and the second vertical portion 16c are placed on the road surface. .

  The first plate 18 supports the first vertical portion 16b, and the second plate 20 supports the second vertical portion 16c, thereby fixing the ring stopper 16 above the tool insertion path X. Specifically, the first plate 18 includes a vertical portion 18a, a folded portion 18b, and a locking portion 18c. The vertical portion 18a has substantially the same length as the first vertical portion 16b. The folded portion 18b is fixed to the vehicle body by welding or the like, and supports the vertical portion 18a so as to extend vertically. At the upper end of the vertical portion 18a, a locking portion 18c that locks the upward movement of the ring stopper 16 is provided.

  Moreover, the 2nd plate 20 has the perpendicular part 20a, the folding | returning part 20b, and the latching | locking part 20c. The vertical portion 20a has substantially the same length as the second vertical portion 16c. The folded portion 20b is fixed to the vehicle body by welding or the like, and supports the vertical portion 20a so as to extend vertically. At the upper end of the vertical portion 20a, a locking portion 20c that locks the upward movement of the ring stopper 16 is provided.

  In the first plate 18 and the second plate 20, the distance between the vertical portion 18a and the vertical portion 20a is substantially the same as the distance between the outer surface of the first vertical portion 16b and the outer surface of the second vertical portion 16c. In addition, the tool insertion path X, that is, the sealing member 12 is attached to the vehicle between the vertical portion 18a and the vertical portion 20a.

  A warning label 22 is affixed to the ring stopper 16. The warning label 22 alerts the operator who is in charge of releasing the braking force of the electric parking brake, such as “use the wheel stopper when releasing the electric parking brake”. The content text is written. Thereby, an operator can be further urged to use the loop fastener 16.
