The adapter includes a flexible printed circuit (FPC). The FPC is disposed on one side of the battery. One end of the FPC is bent between the battery and the charging contact and is electrically connected to the charging contact.
In an embodiment of the present disclosure, the charging apparatus also includes a support member disposed between the battery and the charging contact. The one end of the FPC electrically connected to the charging contact is disposed on the side of the support member facing the charging contact.
In an embodiment of the present disclosure, the FPC is glued to the support member.
An embodiment of the present disclosure provides a charger. The charger is configured to charge the preceding charging apparatus.
In an embodiment of the present disclosure, the charger includes an insulating casing and a pin assembly. The pin assembly includes a pin body and an elastic member. A pilot hole is disposed in the insulating casing. The pin body slidably extends through the pilot hole. One end of the pin body protrudes from the insulating casing. The other end of the pin body is connected to the elastic member. The end of the elastic member facing away from the pin body is stopped in the pilot hole.
In an embodiment of the present disclosure, the pilot hole is a stepped hole. The diameter of the pilot hole facing an insertion end of the insulating casing is greater than the diameter of the pilot hole facing away from the insertion end of the insulating casing. The outer wall of the pin body is provided with a boss. The boss is capable of abutting a step surface in the stepped hole to stop the pin body.
An embodiment of the present disclosure provides a smart wearable device including a housing. The smart wearable device also includes the preceding charging apparatus and charger. The charging apparatus is disposed in the housing.
In the description of the present disclosure, it is to be noted that orientations or position relations indicated by terms such as “center”, “upper”, “lower”, “left”, “right”, “vertical”, “horizontal”, “in”, and “out” are based on the drawings. These orientations or position relations are intended only to facilitate and simplify the description of the present disclosure and not to indicate or imply that a device or element referred to must have such particular orientations or must be configured or operated in such particular orientations. Thus, these orientations or position relations are not to be construed as limiting the present disclosure. Moreover, terms such as “first” and “second” are used only for the purpose of description and are not to be construed as indicating or implying relative importance. For example, the terms “first position” and “second position” are two different positions.
Unless otherwise expressly specified and limited, terms “mounted”, “joined”, “connected”, and “fixed” are to be understood in a broad sense. For example, the term “connected” may refer to “securely connected”, “detachably connected”, may refer to “mechanically connected” or “electrically connected”, or may refer to “connected directly”, “connected indirectly through an intermediary” or “connected inside two components” or “interaction relations between two components”. For those of ordinary skilled in the art, the preceding terms can be construed according to specific circumstances in the present disclosure.
Unless otherwise expressly specified and limited, when a first feature is described as “above” or “below” a second feature, the first feature and the second feature may be in direct contact or be in contact via another feature between the two features. Moreover, when the first feature is described as “on”, “above” or “over” the second feature, the first feature is right on, above, or over the second feature or the first feature is obliquely on, above, or over the second feature, or the first feature is simply at a higher level than the second feature. When the first feature is described as “under”, “below” or “underneath” the second feature, the first feature is right under, below, or underneath the second feature or the first feature is obliquely under, below, or underneath the second feature, or the first feature is simply at a lower level than the second feature.
Technical solutions of the present disclosure are described hereinafter in conjunction with the
In an embodiment of the present disclosure, this embodiment provides a smart wearable device. The smart wearable device includes a housing 1, a charging apparatus and a charger 3. The charging apparatus is disposed in the housing 1. The charger 3 is configured to charge the charging apparatus 2. The smart wearable device may be, but is not limited to, smart glasses or a smart watch. For ease of description, this embodiment is described using an example in which the smart wearable device is smart glasses. The charger 3 of the present disclosure can quickly charge the charging apparatus 2. The preceding charging apparatus 2 and charger 3 are disposed in the smart wearable device of the present disclosure so that the smart wearable device has a good charging performance, a more attractive appearance, and a longer service life.
In an embodiment of the present disclosure, as shown in
In an embodiment of the present disclosure, the charger 3 is connected to the charging contact 23. Electric energy is input to the adapter 22 through the charging contact 23, then input to the motherboard 26 through the adapter 22, and then delivered to the battery 21 through the motherboard 26, thereby achieving the charging of the battery 21. In this embodiment, the charging contact 23 includes the conductive ceramic charging contact 23 so that the conductivity of the charging contact 23 can be improved, the charging contact 23 cannot be corroded, the service life can be prolonged. Moreover, the surface of the charging contact 23 is smoother, and the appearance of the charging contact is more attractive, improving the user experience.
A full resistance test is performed on the charging contact 23 in this embodiment. The test result is as follows:
The charging contact 23 is mostly bonded to the housing 1 through glue, not facilitating disassembly and assembly. To solve the preceding problem, in an embodiment of the present disclosure, the charging apparatus 2 also includes a sealing member 24. The sealing member 24 is disposed between the charging contact 23 and the outer wall 12 of the housing 1. For example, the charging apparatus 2 shown in
In an embodiment of the present disclosure, the charging contact 23 is provided with a sealing groove 231 in a circumferential direction of the charging contact 23. The sealing member 24 is a sealing ring disposed in the sealing groove 231. The sealing ring is easy to assemble and disassemble, thereby facilitating the assembly and disassembly of the charging device 2 in this embodiment.
In an embodiment of the present disclosure, the battery 21 is disposed on one side of the charging contact 23 and spaced apart from the charging contact 23. The adapter 22 includes a FPC. The FPC is disposed on one side of the battery 21. One end of the FPC is bent between the battery 21 and the charging contact 23 and is electrically connected to the charging contact 23. The one end of the FPC is bent and connected to the charging contact 23 so that it is possible to avoid connecting the charging contact 23 to the FPC through the adapter 22, thereby saving both components and space and making the overall structure of the charging apparatus 2 more compact.

In an embodiment of the present disclosure, as shown in
In an embodiment of the present disclosure, the pilot hole 311 is a stepped hole. The diameter of the pilot hole 311 facing an insertion end 312 of the insulating casing 31 is greater than the diameter of the pilot hole 311 facing away from the insertion end 312 of the insulating casing 31. The outer wall 3211 of the pin body 321 is provided with a boss 32111. The boss 32111 is capable of abutting a step surface in the stepped hole 311 to stop the pin body 321. The step in the stepped hole and the boss 32111 can stop the pin body 321 so as to prevent the pin body 321 from disengaging from the insulating casing 31.
