Description

Technical Field

[0001] This utility model relates to the field of car key technology, and in particular to a key shell with a buffer structure. Background Technology

[0002] Car keys typically have mounting holes in the housing to accommodate buttons, and these holes are connected to a cavity housing a circuit board, allowing the buttons to trigger switches on the circuit board. However, this design has the following drawbacks: 1. Poor sealing at the mounting holes allows rainwater and moisture to easily seep into the key, causing short circuits in the circuit board, damaging electronic components, and significantly shortening the lifespan of the car key; 2. Existing car key buttons lack a buffer structure. When a user presses a button, it bottoms out directly, producing a harsh tactile feedback, affecting the user experience. Furthermore, the button's reset relies primarily on the spring force provided by the switch on the circuit board. Due to the limited spring force of the switch, the button's reset effect after pressing is poor, easily resulting in button jamming or failure to rebound properly. Utility Model Content

[0003] The purpose of this invention is to provide a key housing with a buffer structure to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a key housing with a buffer structure, comprising a first housing, a second housing fixedly connected to the first housing, an installation groove on the second housing, an elastic pad disposed in the installation groove, a first button disposed at the top of the elastic pad, a second button disposed on one side of the first button, a third button disposed on one side of the second button, sleeves fixedly connected to the lower surfaces of the first button, a second through hole disposed on the elastic pad at the position corresponding to the sleeve, a first through hole disposed in the installation groove at the position corresponding to the second through hole, and the sleeve passing through the second through hole and fitting into the first through hole.

[0005] Preferably, an elastic sleeve is fixedly connected to the second through hole, and the elastic sleeve is sleeved on the sleeve.

[0006] Preferably, an elastic ring is fixedly connected to the top end of the elastic sleeve, and the elastic ring is sleeved on the sleeve, with a protruding ring fixedly connected to the top end of the elastic ring.

[0007] Preferably, a spring is fitted onto the elastic sleeve, with one end of the spring disposed on the elastic ring and the other end disposed on the elastic pad.

[0008] Preferably, the lower surfaces of the first button, the second button, and the third button are provided with ring grooves at the positions corresponding to the raised rings, and the raised rings are disposed in the ring grooves.

[0009] Preferably, the lower surfaces of the first button, the second button, and the third button are all fixedly connected with trigger rods, and the trigger rods are sleeved inside the sleeve.
