Description

Technical Field

[0001] This utility model relates to the field of automotive key technology, and in particular to a locking bracket and a key. Background Technology

[0002] Some keys, such as vehicle keys, consist of both electronic and mechanical components to address situations where the remote control system fails. These vehicle keys typically have a movable bracket; the mechanical key automatically engages with the bracket when inserted into the key housing, and the mechanical key can be removed by pressing the bracket. However, because the bracket only has a latch on one side, if the bracket is installed incorrectly, the mechanical key cannot engage with the latch, preventing it from being inserted into the key housing and requiring rework, thus increasing production costs. Utility Model Content

[0011] Furthermore, a second guide surface is provided on one side of the second fixing part, and a second anti-detachment part is provided on the other side of the second fixing part. The angle between the second guide surface and the first direction is smaller than the angle between the second anti-detachment part and the first direction. The first direction is along the positive half axis of the X-axis.

[0012] Furthermore, the housing includes an upper shell and a lower shell connected to each other, the space enclosed by the upper shell and the lower shell constitutes the mounting cavity of the support body, and the upper shell is provided with a window for movably setting the support body; a gap is also provided between the upper shell and the lower shell for inserting the mechanical key.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model proposes a locking support, comprising a support body, a fixing hole, and a first fixing part within the fixing hole. The first fixing part is used for detachably engaging with a mechanical key. An attitude indicator surface is provided on the outer side of the support body to instruct the operator to install the support body in a preset posture at a designated position, preventing incorrect installation and ensuring that the mechanical key engages with the first fixing part when inserted. Specifically, the attitude indicator surface includes a first indicator surface and a second indicator surface on the outer side of the support body. The first and second indicator surfaces have different surface shapes for easy observation by the operator.

[0017] 2.

Detailed Implementation

[0027] Example 1

[0028] The following is combined with Figures 1-2 This utility model will be described in detail.

[0029] A locking support includes a support body 10, the support body 10 having a fixing hole 101, a first fixing part 30 inside the fixing hole 101, the first fixing part being detachably engaged with a mechanical key 20, and an attitude indicator surface on the outer side of the support body 10, for instructing the operator to install the support body 10 in a preset attitude at a designated position, avoiding incorrect installation of the support body 10, and ensuring that the mechanical key 20 can be engaged with the first fixing part 30 when inserted.

[0030] In this embodiment, the attitude indicator surface includes a first indicator surface 102 and a second indicator surface 103 disposed on the outer facade of the support body 10. The first indicator surface 102 and the second indicator surface 103 have different surface shapes, such as... Figure 1 As shown, the first indicator surface 102 is an outwardly convex arc shape, and the second indicator surface 103 is a plane. In other embodiments, more attitude indicator surfaces and indicator surfaces of other shapes may also be provided. Furthermore, the first indicator surface 102 and the second indicator surface 103 are respectively provided at opposite ends of the outer facade of the support body 10.

[0031] In this embodiment, a first guide surface 301 is provided on one side of the first fixing part 30, and a first anti-detachment surface 302 is provided on the other side of the first fixing part 30. The angle α1 between the first guide surface 301 and the first direction is greater than the angle α2 between the first anti-detachment surface 302 and the first direction. The first direction is the direction along the positive half-axis of the X-axis, that is, α1>α2. Figure 2 As shown. When the mechanical key 20 is inserted and abuts against the first guide surface 301, compared to when the mechanical key 20 is pulled out and abuts against the first anti-disengagement surface 302, the mechanical key 20 is more likely to push the support body 10 downward during insertion, which facilitates the insertion of the mechanical key 20 and at the same time prevents the mechanical key 20 from falling out when not in use.

[0032] In this embodiment, the bottom end of the support body 10 is provided with a groove 104 for installing the reset spring 50, so that the support body 10 is in contact with the inner side of the housing by the elastic force of the reset spring 50, thus preventing the support body 10 from detaching from the housing.

[0033] Example 2

[0034] The following is combined with Figures 3-4 This utility model will be described in detail.

[0035] A key 80 includes a housing, on which the aforementioned locking support is movably mounted, and a mechanical key 20. The mechanical key 20 is provided with a second fixing part 40. A return spring 50 is provided between the locking support and the housing. The return spring 50 is used to control the locking support to move in the opposite direction of its pressing direction, so that the first fixing part 30 is engaged with the second fixing part 40.

[0036] In this embodiment, a second guide surface 401 is provided on one side of the second fixing part 40, and a second anti-detachment part 402 is provided on the other side of the second fixing part 40. The angle β1 between the second guide surface 401 and the first direction is smaller than the angle β2 between the second anti-detachment part 402 and the first direction. The first direction is the direction along the positive half-axis of the X-axis, i.e., β1>β2. Figure 2 .

[0037] When the mechanical key 20 is inserted, the second guide surface 401 abuts against the first guide surface 301, thereby pushing the support body 10 downward. As the mechanical key 20 continues to be pushed, the second guide surface 401 disengages from the first guide surface 301. Under the elastic force of the return spring 50, the support body 10 moves upward. If the mechanical key 20 moves outward at this time, the second anti-disengagement part 402 abuts against the first anti-disengagement surface 302, restricting the mechanical key 20 from moving outward. When the mechanical key 20 needs to be used, press the support body 10 to overcome the elastic force of the return spring 50, so that the first anti-disengagement surface 302 disengages from the second anti-disengagement part 402, and the mechanical key 20 can be removed.

[0038] In this embodiment, the housing includes an upper shell 60 and a lower shell 70 connected to each other. The space enclosed by the upper shell 60 and the lower shell 70 constitutes the mounting cavity of the support body 10. The upper shell 60 is provided with a window 601 for movably setting the support body 10. A gap for inserting a mechanical key 20 is also provided between the upper shell 60 and the lower shell 70.

[0039] In this embodiment, a plug-in 105 is provided at the top of the support body 10. The plug-in 105 is movably disposed within the window 601, and the lateral dimension H1 of the top of the support body 10 is greater than the lateral dimension H2 of the window 601, i.e., H1>H2. Figure 4 As shown, the support body 10 is pressed against the inner side of the housing by the spring force of the return spring 50, so as to prevent the support body 10 from detaching from the housing.

[0040] In this embodiment, the lower shell 70 is provided with a mounting post 701, one end of the return spring 50 is sleeved on the mounting post 701, and the other end of the return spring 50 abuts against the support body 10. Specifically, the return spring 50 abuts against the groove 104, such as... Figure 4 As shown.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
