The key part has simple structure, easy installation and good use effect.

In this embodiment, referring to fig. 1, 8 and 9, two upper charging pins 401 in this embodiment are all disposed through the insertion protrusion 101, in an initial state, the top ends of the upper charging pins 401 are exposed to the insertion protrusion 101, and the exposed portions of the upper charging pins 401 should be set as short as possible on the premise of meeting the requirement of conducting with the to-be-charged member. When the key part slides down, the upper charging pin 401 can slide under the guide of the through hole formed with the insertion projection 101. Compared with the prior art, the longer scheme of setting the exposed size of the upper charging needle 401 can prevent the upper charging needle 401 from being distorted and deformed during the use process, thereby being beneficial to prolonging the service life of the upper charging needle 401.

Further, as shown in fig. 2 to 5, a fixing plate 5 is provided between the upper PCB 4 and the lower cover 7 in the present embodiment. The magnetic attraction portion includes a first magnet 501 provided on the fixed plate 5. The fixing plate 5 is circular in shape as a whole, two first magnets 501 are oppositely arranged on the fixing plate 5, and in order to improve the specification of the first magnets 501, the two first magnets 501 are in an arc shape coaxially arranged with the fixing plate 5. In addition, the two first magnets 501 are oppositely arranged at two sides of the insertion protrusion 101, and the magnetic attraction fitting on the member to be charged may be a first fitting magnetically connected with the first magnets 501.

Further, the magnetic attraction part in this embodiment further includes a second magnet 402 disposed on the upper PCB 4. As also shown in connection with fig. 2-5, the second magnets 402 in this embodiment are also two oppositely disposed on the upper PCB board 4. The magnetically attractive mating element on the part to be charged may be a second mating element magnetically coupled to the second magnet 402. The two first magnets 501 and the two second magnets 402 are staggered in the circumferential direction of the key portion, and the specifications of the two second magnets 402 are matched with the specifications of the insertion projection 101, and the specifications of the second magnets 402 are smaller than those of the first magnets 501.

Here, the two second magnets 402 cooperate to further enhance the connection strength between the insertion projection 101 and the insertion, thereby preventing the to-be-charged member from falling off from the key portion in a natural state. It should be noted that, in the implementation, a solution in which only one of the first magnet 501 and the second magnet 402 is provided is also possible on the premise of meeting the requirement that the member to be charged is connected to the key portion. In particular, one of the magnet and the mating member may be a magnet, and the other may be an iron block, so long as the magnet and the mating member can be magnetically attracted together.

In this embodiment, as shown in fig. 5 to 8, the switch portion is a bump 802 disposed on the lower PCB 8 and protruding upward, and the bump 802 is electrically connected to the lower PCB 8. Corresponding to the projection 802, the lower cover 7 is provided with a through hole 701 penetrating therethrough, and the bottom of the fixing plate 5 is provided with a recess 502 having a downward opening. In the initial state, a target distance is provided between the top end of the bump 802 and the bottom of the groove 502. The target pitch here is based on the stroke setting of the key section sliding when the key function is implemented.

As the key portion slides downward, the distance between the bottom of the groove 502 and the top of the bump 802 becomes smaller, and when the top of the bump 802 abuts against the bottom of the groove 502, the switch portion is triggered, so that the external control unit outputs a preset control command. The external control unit and the specific preset control command can be determined according to the use requirement of the key structure.

In addition, the elastic member in the present embodiment includes a spring 6 disposed between the key portion and the base portion, and the spring 6 is capable of deforming and accumulating energy due to sliding of the key portion when the key portion is pressed by an external force, and is capable of driving the key portion to slide to an initial position to return by releasing the energy accumulation after the external force is lost.

In a specific structure, as shown in fig. 8 and 9, the springs 6 in the present embodiment are four arranged at intervals along the circumferential direction of the key portion, which is advantageous in improving the stability of the key portion in sliding. The spring 6 can be sleeved on the connecting column 201, one end of the spring 6 is connected with the cover plate 2, and the other end is connected with the lower cover 7. When the key part slides downwards under the action of external force, the spring 6 is stretched to store energy, and when the external force disappears, the spring 6 releases the energy storage to reset, and simultaneously drives the key part to slide upwards to reset.

It should be noted that the spring 6 in this embodiment may also be connected to the rear case 9 at one end and to the lower cover 7 at the other end, except that at this time, the spring 6 compresses the stored energy when the key part slides down. Of course, the arrangement position, the number and the like of the springs 6 can be adaptively adjusted according to the use requirements.

In the key structure described in this embodiment, in the initial state, the upper charging pins 401 and the lower charging pins 801 are in a one-to-one conduction state. When the key structure is used for charging, the piece to be charged can be directly charged by being adsorbed and inserted on the key part through the first magnet 501 and the second magnet 402, and the key part is not required to be pressed by external force in the charging process.

When the key function is needed to be used in the charging process, the key part (or the piece to be charged) is pressed by external force, the key part and the piece to be charged synchronously slide downwards, at the moment, the head of the lower charging needle 801 is compressed, the upper charging needle 401 and the lower charging needle 801 are always kept in a conducting state until the groove bottom of the groove 502 in the key part is abutted with the convex block 802, the key part cannot continuously slide downwards, the lower PCB 8 is conducted with an external control unit, and the external control unit outputs a preset control instruction, so that the charging function is not influenced while the key function is realized.

The key structure of this embodiment is in the same place with key function and function integration that charges, can reduce the space occupation, can also use the key function alone, use the function of charging alone to and use key function and function of charging simultaneously, and have better result of use, and have better practicality.
