Detailed ways

The present invention is further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

As shown in FIG. 1 to FIG. 4 , the present invention provides a double-pull and unlock type hood lock (hereinafter referred to as the hood lock), which mainly lies in that the user only needs to pull twice to completely unlock the hood lock without locking the engine. cover. The hood lock 100 includes a carrier 1 , a relay member 2 , an unlocking member 3 and an elongated structure 4 , and preferably also includes a blocking body 42 , a locking hook 5 and a top-height structure 6 . Among them, the relay 2, the unlocking member 3 and the locking hook 5 are all pivotally connected to the carrier 1 and can rotate relative to the carrier 1; the relay 2, the unlocking member 3 and the locking hook 5 are respectively matched with the carrier 1. A first elastic member 13 (only shown in FIG. 3 , not shown in other figures) is provided, so that the relay member 2 , the unlocking member 3 and the locking hook 5 can all rotate relative to the carrier 1 to generate an elastic restoring force.

The carrier 1 can be any object with a bearing function, such as a complete shell (not shown in the figure), or can be a two-piece shell as shown in Figures 1 and 2: including a seat plate 1a and a corresponding seat plate 1a covers an outer cover 1b. The carrier 1 defines a groove 12 and is movably configured with a lock assembly 11. The lock assembly 11 may include, for example, a lock tongue 111 and a lock lever 112. The lock tongue 111 is pivotally connected to the carrier 1 corresponding to the position of the groove 12, and the lock lever 112 Then it can move in the groove 12 and can be restricted by the tiger mouth 1111 of the locking tongue 111, and the locking rod 112 is connected to the engine cover (not shown in the figure).

The relay 2 has a plurality of steps for blocking the lock assembly 11 and an actuated portion 23 . Specifically, the plurality of gear steps include a first gear step 21 and a second gear step 22 protruding in a stepped shape relative to the first gear step 21 , that is, the first gear step 21 and the second gear step 22 are mutually The class protrudes to form a ladder shape. Specifically, the first gear step 21 and the second gear step 22 are both located at one end of the relay member 2 , and the actuated portion 23 is located at the other end of the relay member 2 . It is then pivotally connected to the carrier 1 by a pivot member (component symbol not shown), and the relay member 2 can also be subjected to the aforementioned elastic restoring force to move relative to the carrier 1 in a locking direction (sequentially) with the pivot member as the axis. clockwise) rotation.

The unlocking member 3 has a pulling portion 31 and a driving portion 32 corresponding to the driven portion 23 , and the unlocking member 3 can only be rotated by a driving angle. Specifically, the pulling part 31 is connected with a pulling cable 800 for the user to pull; the unlocking member 3 enables the user to have a pre-rotation state by pulling or releasing the pulling cable 800 (see FIG. 3 or FIG. 4 ), a rotating In the post-rotation state (see FIG. 6 ) and a released state (see FIG. 7 ); and, in the post-rotation state, the unlocking member 3 can directly or indirectly abut the driven portion 23 with its driving portion 32 to drive the relay member 2 toward a Rotate in the unlocking direction (ie, counterclockwise). The unlocking member 3 can be bent in a V shape and is pivotally connected to the carrier 1 by the same pivoting member at the bending position.

The elongated structure 4 can be pivotally connected to the relay member 2 or the unlocking member 3 , and the elongated structure 4 has an elongated arm 411 . The elongated structure 4 can be driven (for example, driven by the elastic restoring force generated by the first elastic member 13 ) to bridge or not bridge between the driving portion 32 and the driven portion 23 with its elongated arm 411 ; wherein, When the extension arm 411 spans between the driving part 32 and the driving part 23 , the driving part 32 or the driving part 23 can be lengthened.

The present invention does not limit that the elongated structure 4 should be pivotally connected to the relay member 2 or the unlocking member 3, as long as the elongated structure 4 can use its elongated arm 411 to lengthen the actuated portion 23 or lengthen the driving portion 32, in this embodiment In the example, the corresponding actuated portion 23 is pivotally connected to the relay member 2 as an example for description.

Therefore, when the user has not pulled the cable 800, as shown in FIG. 4, the unlocking member 3 is in the state before rotation. The rod 112 is restricted by the tiger's mouth 1111 and is in a locked state. When the user pulls the cable 800 for the first time, as shown in FIG. 5 and FIG. 6 , the unlocking member 3 will rotate by the aforementioned driving angle to be in the state after the first rotation, and the driving part 32 directly abuts the driving part 23 The relay 2 is driven to rotate by a first unlocking angle, so that the locking rod 112 first escapes the restriction of the tiger's mouth 1111 , and is then blocked by the second gear 22 to be in a quasi-unlocking state. When the user first releases and then pulls the cable 800 for the second time, as shown in FIG. 7 , FIG. 8 and FIG. 9 , the unlocking member 3 will still rotate by the aforementioned driving angle and be in the state after the second rotation, and the driving part 32 indirectly abuts the receiving portion 23 through the bridged extension arm 411 to drive the relay member 2 to rotate by a second unlocking angle, and the second unlocking angle is greater than the first unlocking angle, so that the locking rod 112 is separated from each of the relay member 2. The lock is unlocked by the stop of the step. In other words, the driving part 32 is in direct contact with the receiving part 23 after the first rotation, so as to prevent the extension arm 411 of the extension structure 4 from rotating in a positive direction (eg, clockwise) relative to the relay member 2; At this time, in the state after the first rotation of the unlocking member 3, its driving portion 32 will directly drive the relay member 2 to rotate the first unlocking angle. In short, the unlocking member 3 can drive the relay member 2 to rotate at two different unlocking angles at the same driving angle: the first unlocking angle and the second unlocking angle.

Preferably, the elongated structure 4 can be a swivel 41 and has the aforementioned elongated arm 411 and a blocking portion 412 , and the blocking body 42 is disposed on the carrier 1 corresponding to the blocking portion 412 , so that the blocking body 42 is located in the movement of the blocking portion 412 . on the path. As a result, the first effect, the second effect, or the first and second effects will be produced, as will be described later. The first function: the blocking body 42 and the driving part 32 can alternately block the blocking part 412 and the extension arm 411 in the state before the rotation and the state after the first rotation, respectively, so that the extension structure 4 cannot temporarily be relative to each other according to the elastic reset force. Rotate in the forward direction (for example: clockwise) of the relay 2. The second function: when the relay member 2 rotates in the locking direction due to the action of the first elastic member 13, the extension structure 4 can be driven to reverse (eg, counterclockwise) with its blocking portion 412 being blocked by the blocking body 42. The rotation is back to positive, that is, it can be reversed to return to the state before rotation.

As mentioned above, when the user releases the cable 800, as shown in FIG. 7, the unlocking member 3 will be in a released state and can rotate clockwise due to the action of the first elastic member 13. 32 is far away from the actuated portion 23 and no longer blocks the extension arm 411 of the extension structure 4 , and also keeps the blocking portion 412 away from the blocking body 42 , that is, the blocking body 42 no longer blocks the blocking portion 412 of the elongated structure 4 . In this way, the elongated structure 4 can be rotated clockwise by the action of the first elastic member 13, and the elongated arm 411 is bridged between the driving part 32 and the driven part 23. At this time, the unlocking member 3 will be able to In the state after the second rotation, the driving part 32 indirectly drives the relay 2 to rotate the second unlocking angle through the extension arm 411 .

In addition, as shown in FIGS. 8 and 9 , the locking hook 5 has a hook portion 51 and a driven portion 52 , and the top-height structure 6 is disposed on the carrier 1 corresponding to the driven portion 52 and has a retracted state. After the second rotation of the unlocking member 3, the extension arm 411 will indirectly drive the relay member 2 to rotate the second unlocking angle, so that the lock hook 5 hooks its hook portion 51 to the relay member 2 that has been rotated by the second unlocking angle. to keep the relay 2 at the second unlocking angle. The top-height structure 6 includes a top-height cylinder 61 and a second elastic member 62 connected between the top-height cylinder 61 and the carrier 1 , so as to elastically lift the engine cover.

As shown in FIG. 4 , when the user closes the hood to the vehicle body, the interlocking locking rod 112 and the roof structure 6 are moved down together. At this time, the top-height structure 6 will abut against the driven portion 52 in the aforementioned retracted state, so as to drive the locking hook 5 to disengage from the protruding column 24 of the relay member 2, so that each component (such as the relay member 2, etc.) can be Use the elastic reset force to return to the original position.

As shown in FIG. 10 , when the hood is closed on the vehicle body, the locking lever 112 will follow the hood and move down in the groove 12 to a predetermined closing position (that is, when the hood is normally closed, The position of the locking lever 112 relative to the groove 12, see Figure 4). The hood lock 100 of the present invention further has the buffering effect when pedestrians hit the hood, so the depth of the groove 12 is specially designed to be much larger than the predetermined cover position, that is, the lower end of the groove 12 has a depth much larger than the predetermined cover position. A section of impact buffering length is used to utilize this impact buffering length to have the impact buffering effect.

To sum up, compared with the prior art, the present invention has the following effects: the hood lock 100 can be completely unlocked only by the double-pull action (the existing hood lock can only be pulled by a single pull), and the user does not need to Then, the fingers can be inserted into the engine room through the gap between the hood and the vehicle body to carry out troublesome unlocking, which has the effect of convenience.

In addition, the present invention also has other effects: the groove 12 of the hood lock 100 also has an extended buffer length, so it has a buffering effect when pedestrians hit the hood.

The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention is subject to the claims.
