Embodiment Construction

[0023] The structure of existing smart products with buttons is as follows: the sleeve is welded or glued to the shell, the waterproof O-ring and spring are placed on the button, put into the sleeve, and then the C-ring is stuck on the button The tail card slot can trigger the electronic work by pressing the button. The disadvantage of the above structure is that when the smart product falls, the impact of the buttons on the electronic parts after the fall will cause the function of the smart product to fail.

[0024] The design concept of the present invention is: in order to solve the problem that the function of the product fails due to the impact of the key on the electronic parts when the existing key smart product falls, the present invention installs a special ring protection device 8 on the ordinary key shaft, and A card slot is opened in the annular area where the protection device is installed on the key shaft body. When the smart product falls, the protection devic...

Abstract

The invention belongs to the technical field of electronic equipment, and especially relates to a key protection device. The device comprises a key, a housing, a housing cover, a plug connector, an elastic part, a sliding block, a connecting part, and a pulling body. The housing sleeves a shaft of the key, and an annular clamping groove is disposed at a position, corresponding to the housing, of the shaft of the key. One end of the housing is a closed end, and the other end of the housing is connected with the housing cover. The inner side of the closed end of the housing is provided with an inner chute and an outer chute. The sliding block and the pulling body are respectively in sliding connection with the inner chute and the outer chute. One end of the connecting part is connected with the pulling body, and the other end of the connecting part passes through the sliding block to be connected with the plug connector. The plug connector is corresponding to the annular clamping groove. The elastic part is located between the plug connector and the sliding block, and is in a compression state under the action of the gravity of the pulling body. The device can protect the internal electronic parts when a product falls, and prevents the impact of the key from causing the failure of the product.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a key protection device. Background technique [0002] Smart products, such as smart watches and smart bracelets, are products that use buttons. Most of the buttons of the above-mentioned smart products use button structures. figure 1 shown. The key application fields of this structure are very extensive, and intelligent products are developing vigorously. [0003] like figure 1 As shown in the schematic diagram of the current button structure, the sleeve 50 is welded or glued on the housing 40, the waterproof O-ring 80 and the spring 60 are placed on the button 70, put into the sleeve 50, and then the C-shaped ring 90 is clamped. The slot at the tail of the key, pressing the key can trigger the electronic part 30 to work. [0004] At present, the buttons of smart products have the following defects: when dropped, the buttons 70 will impact the electr...
