Detailed Description

In order to make the technical solutions and advantages of the present invention more apparent, exemplary embodiments of the present invention are described in further detail below with reference to the accompanying drawings. It is clear that the described embodiments are only a part of the embodiments of the utility model, and not an exhaustive list of all embodiments. And the embodiments and features of the embodiments may be combined with each other without conflict.

An embodiment of the present invention provides an automotive spare key 10. As shown in fig. 1, an automobile spare key 10 includes a blank gear 1 and a key lever 2. Wherein the blank 1 is intended to be inserted into a key hole of a back-up lock 3. After the gear blank 1 is inserted into the key hole, the key handle 2 is mainly exposed outside the key hole and used as a screwing force application member to drive the gear blank 1 to carry out unlocking operation. In the present application, the key handle 2 is not fixedly connected to the blank 1, but is hinged. In particular, the connecting end of the key lever 2 is hinged to the connecting end of the blank 1 for enabling the free end of the key lever 2 to perform a movement towards or away from the blank 1 within a predetermined angular range around the hinge point of the blank 1 to the key lever.

Thus, the automobile spare key 10 is inserted into the spare lock 3, as shown in fig. 6 a. At this time, if the spare key of the automobile in the prior art is adopted, the free end of the key handle is very close to the automobile door, the rotating space for unlocking is seriously insufficient, and the problem of scratching the automobile door exists. However, if the automobile spare key 10 of the present application is used, the key lever 2 is first rotated so that the free end of the key lever 2 is rotated away from the hinge end, and thus the free end of the key lever 2 can be moved away from the door 4 of the automobile, as shown in fig. 6 b. At the moment, the key handle 2 drives the gear blank 1 to rotate so as to carry out unlocking operation, and the key handle 2 has enough rotating space, so that the scratch of the vehicle door 4 can be effectively avoided.

In one embodiment, a rotation assembly is provided between the connecting end of the key lever 2 and the connecting end of the tooth blank 1. The rotary assembly has a tooth blank insert 5 fixedly connected to the connecting end of the tooth blank 1, a key handle insert 6 fixedly connected to the connecting end of the key handle 2, and a connecting pin 7 passing through the key handle insert 6 and the tooth blank insert 5. The articulation between the blank 1 and the key shank 2 is achieved by the above-mentioned connection.

Specifically, as shown in fig. 3, the blank insert 5 includes a hinge 51. The hinge portion 51 is provided with a first hinge hole 52. Meanwhile, as shown in fig. 2, the key handle insert 6 includes a key handle insert body 61 and two spaced engaging lugs 62 fixedly disposed on the inner side (the side facing away from the key handle 2) of the key handle insert body 61. Wherein the key handle insert body 61 is substantially in the form of a long plate, and the outer side surface (the side surface for connecting the key handle 2) thereof is a curved surface for fittingly fitting on the inner side of the key handle 2 (the side surface for connecting the key handle insert body 61). A second hinge hole 63 is provided at the coupling lug 62. During the connection process, the hinge portion 51 is adapted to be inserted between the two engaging lugs 62. The blank insert 5 and the key shank insert 6 are then connected by the connecting pin 7 through the first hinge bore 52 and the second hinge bore 63. The blank insert 5 and the key shank insert 6 can thus perform a relative rotational movement about the connecting pin 7. The above-described structural arrangement enables articulation between the key handle 2 and the blank 1.

As shown in fig. 4 and 5, one end of the hinge portion 51 remote from the tooth blank 1 is configured in an arc shape that protrudes. Meanwhile, an inwardly concave arc shape is provided on the inner side of the key handle insert body 61 for matching with one end of the hinge portion 51 away from the blank 1. The arrangement forms a movement connecting pair similar to a joint shape, so that one end of the hinge part 51 far away from the gear blank 1 can be better guided to move under the inner concave arc of the key handle insert body 61, the moving surfaces are tightly attached, and the movement stability is further ensured.

A movement limit is arranged between the gear blank insert 5 and the key handle insert 6 for ensuring a preset angle of relative movement between the two. The hinge portion 51 is provided with a first contact stopper portion 53 in a protruding manner. Meanwhile, a second abutting limit part 64 is provided on the key shank insert body 61 for cooperation with the first abutting limit part 53. As shown in fig. 4, at the start of the relative movement, the second abutment stopper portion 64 is seated on the first abutment stopper portion 53. Preferably, the first abutment limit portion 53 is in inclined surface fit with the second abutment limit portion 64. For example, the first abutment stopper portion 53 is formed in a substantially triangular shape in the cross section of fig. 4. This arrangement can ensure better contact between the first abutment stopper portion 53 and the second abutment stopper portion 64.

Further, the hinge portion 51 is provided with a third contact stopper portion 54. The third abutting limiting portion 54 and the first abutting limiting portion 53 are spaced by a predetermined angle range. Meanwhile, a fourth abutment stopper 65 for engaging with the third abutment stopper 54 is provided on the key holder insert body 61. As shown in fig. 5, at the end of the relative movement, the fourth abutment stopper portion 65 abuts against the third abutment stopper portion 54 to restrict the further rotation of the key lever 2. For example, the third abutment limit portion 54 may be configured as a plane of the hinge portion 51 that faces away from the first abutment limit portion 53. And the fourth abutment limit portion 65 is configured at the outermost end of the key shank insert body 61 remote from the key shank 2 and beyond the second hinge hole 63. Thereby, during rotation of the key lever 2 relative to the blank 1, the fourth abutment limit portion 65 abuts against the third abutment limit portion 54 for limiting further rotation of the key lever 2.

In one embodiment, the blank insert 5 further comprises a cylindrical fixing portion 55 fixedly connected to the hinge portion 51. The attached end of the blank 1 is inserted into the cavity of the fixing portion 55. The tooth blank insert 5 is a plastic part and is integrally injection-molded with the tooth blank 1. This connection is simple and ensures the strength of the connection between the tooth blank insert 5 and the tooth blank 1.

The key handle 2 is a metal piece or a plastic piece, the key handle insert 6 is a plastic piece, and the key handle 2 and the key handle insert 6 are integrally formed in an injection molding mode. This connection is simple and easy to produce, and ensures the connection strength between the key handle 2 and the key handle insert 6.

The connecting pin 7 may be a metal piece, for example a steel metal piece. Meanwhile, the connecting pin 7 is in interference fit with the first hinge hole 52 and the second hinge hole 63, so as to improve the connecting strength.

In one embodiment, the predetermined angular range of rotation of the key lever 2 about the hinge point of the blank 1 and the key lever 2 may be 20-80 degrees, for example, 50 degrees.

The present application also includes automobiles. A back-up lock 3 is provided on the door 4 and a car back-up key 10 of the present application is mated to the back-up lock 3 for opening the door in the event of a car power outage.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, the appended claims are intended to be construed to include preferred embodiments and all such variations and/or modifications as fall within the scope of the utility model, which are intended to be covered by the embodiments of the utility model.
