[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0036] like Figures 1 to 5 As shown, an embodiment of the utility model provides a charging PIN electrical connection structure, including:

[0037] The housing 10 can be made of a hard material. The housing 10 has a storage space 11 therein to accommodate electronic components of the electronic device such as a processor, a sensor, a battery, etc. An opening 12 is formed on the housing 10 to connect the storage space 11 with the outside.

[0038] The mounting frame 20 can be fixed in the opening 12 by various methods such as welding, bonding, clamping, and integrated injection molding, which are not limited here. A plurality of mounting holes 21 are provided on the mounting frame 20, and the mounting holes 21 are used to fix the PIN needle 30. The mounting holes 21 are connected to the accommodating space 11. The number of the mounting holes 21 is not limited and can be determined according to the PIN needle 30. In a feasible implementation manner, the shape of the opening 12 is a waist-shaped structure, and the outer contour surface of the mounting frame 20 matches the inner contour surface of the opening 12. There are four mounting holes 21, and the four mounting holes 21 are arranged in sequence along the long axis direction of the mounting frame 20.

[0039] Multiple PIN pins 30 are fixed one by one in multiple mounting holes 21. The PIN pins 30 play a role in conducting electricity and transmitting signals. The material of the PIN pins 30 can be conductive metal or conductive ceramic, etc., which is not limited here. The PIN pins 30 include a first contact surface 31 and a second contact surface 32. The first contact surface 31 extends into the accommodating space 11 through the mounting hole 21, and the second contact surface 32 is located outside the accommodating space 11.

[0040] The main board 40 is accommodated in the accommodating space 11. The main board 40 can be a flexible circuit board, a printed circuit board, etc., which can be limited here. A battery module (not shown) is also provided in the accommodating space 11, and the main board 40 is electrically connected to the battery module.

[0041] The electrical connector 50 has a first end electrically connected to the main board 40, a welding piece is provided on the main board 40, the electrical connector 50 is connected to the main board 40 via the welding piece, and the second end of the electrical connector 50 is elastically abutted against the first contact surface 31. When charging is required, the charging head of the external power supply (not shown) contacts the second contact surface 32, and the electric energy of the external power supply is sequentially transmitted to the battery module through the PIN needle 30, the electrical connector 50 and the main board 40, thereby realizing the charging of the battery module by the external power supply.

[0042] In a feasible implementation, the electrical connector 50 is a spring structure, and the mainboard 40 is electrically connected by the spring structure and the spring contact on the PIN pin 30, thereby conducting the external power supply and the mainboard 40. The electrical connector 50 with a spring structure can make the electrical connection method simpler, facilitate the installation and disassembly of the mainboard 40, and make more reasonable use of the space structure in the electronic device. The specific shape and structure of the spring structure can refer to the corresponding content in the prior art, and will not be repeated here.

[0043] in:

[0044] In order to improve the connection reliability between the electrical connector 50 and the PIN needle 30 and avoid the electrical connector 50 and the PIN needle 30 from being out of contact, refer to Figure 1 as well as Figure 3 As shown, the first contact surface 31 is a plane extending along the first direction D1, and the axial direction of the PIN needle 30 is parallel to the first direction D1. In a feasible implementation, in the area where the first contact surface 31 is located, the cross-section along the radial direction of the PIN needle 30 is a "D"-shaped structure. The spring structure of the electrical connector 50 enables the electrical connector 50 to accumulate elastic restoring force. By utilizing this elastic restoring force, the second end of the electrical connector 50 can continuously press against the first contact surface 31, while effectively preventing the abutment of the electrical connector 50 from deviating.

[0045] In the embodiment provided by the utility model, the first contact surface 31 is a plane, the second end of the electrical connector 50 is in surface contact with the first contact surface 31, and the electrical connector 50 only abuts against a local area of ​​the first contact surface 31. Even if the position of the electrical connector 50 is offset, the second end of the electrical connector 50 is still on the first contact surface 31, thereby improving the electrical connection stability between the electrical connector 50 and the PIN needle 30 and reducing the occurrence of the electrical connector 50 and the PIN needle 30 being out of contact.

[0046] Reference Figure 1 As shown, a bracket 13 is provided in the accommodating space 11, and one end of the bracket 13 can be fixed to the inner wall surface of the shell 10 by various methods such as welding, bonding, clamping, and integrated injection molding, which are not limited here. The other end of the bracket 13 is connected to the main board 40, and the main board 40 is fixed in the accommodating space 11 through the bracket 13, so that the main board 40 maintains a predetermined posture in the accommodating space 11, and the extension direction of the board surface of the main board 40 is parallel to the extension direction of the first contact surface 31. The main board 40 and the first contact surface 31 are arranged in parallel, and the distance between the two is relatively close, which can effectively compress the occupied space, and at the same time is conducive to the arrangement of the electrical connector 50, simplifying the product stacking structure.

[0047] The first end of the electrical connector 50 is welded to the area of ​​the mainboard 40 close to the mounting frame 20. Along the first direction D1, the mainboard 40 can be artificially divided into an upper half area and a lower half area, wherein the upper half area is closer to the mounting frame 20 than the lower half area. The electrical connector 50 is located in the upper half area, and the projection of the PIN pin 30 in the normal direction of the mainboard 40 also only falls on the upper half area of ​​the mainboard 40 and is suspended. In the lower half area of ​​the mainboard 40, an installation gap is reserved for other components, thereby making more reasonable use of the spatial structure and reducing the difficulty of assembling the components.

[0048] In a feasible implementation manner, the PIN pin 30 is installed into the mounting hole 21 along the first direction D1, the axial direction of the mounting hole 21, the extension direction of the first contact surface 31, and the axial direction of the PIN pin 30 are all parallel to each other, and the PIN pin 30 is vertically assembled into the mounting hole 21 from top to bottom to avoid contact wear on the PIN pin 30 during the installation process, thereby improving the charging reliability of the product.

[0049] Furthermore, the PIN pin 30 is fixed in the mounting hole 21 by an interference fit, and the PIN pin 30 can be stably set in the mounting hole 21 without displacement or twisting, which facilitates the installation of the PIN pin 30 and can effectively ensure that the electrical connector 50 welded on the mainboard 40 is in good contact with the PIN pin 30, ensuring the flatness of the first contact surface 31 where the PIN pin 30 contacts the electrical connector 50, so that the first contact surface 31 is always opposite to the electrical connector 50, thereby improving the stability of the conductive contact performance.

[0050] Reference Figure 3 As shown, the second contact surface 32 is a plane extending along the second direction D2, the second direction D2 is perpendicular to the first direction D1, the second contact surface 32 extends along the radial direction of the PIN needle 30, the radial cross-section of the PIN needle 30 is circular, the charging head of the external power supply abuts against the second contact surface 32, the second contact surface 32 is a horizontally extending plane, and the charging head of the external power supply is in surface contact with the second contact surface 32, which increases the contact area with the charging head and improves the electrical connection stability between the charging head and the PIN needle 30.

[0051] Reference Figure 2 As shown, a first protrusion 22 is convexly provided on the inner wall surface of the mounting hole 21. The shape and size of the first protrusion 22 are determined according to actual needs and are not limited here. A contact surface 23 is formed on the first protrusion 22, and the contact surface 23 is a plane extending along the second direction D2.

[0052] Reference Figures 3 to 5 As shown, the PIN needle 30 includes a first main body section 301 and a second main body section 302 connected to each other, a first contact surface 31 is formed on the outer surface of the first main body section 301, and a second contact surface 32 is formed on a side of the second main body section 302 away from the first main body section 301. The diameter of the first main body section 301 is smaller than the diameter of the second main body section 302. A contact surface 33 is formed between the first main body section 301 and the second main body section 302, and the contact surface 33 is also a plane extending along the second direction D2.

[0053] When the PIN pin 30 is assembled into the mounting hole 21, the abutting surface 33 is pressed against the abutted surface 23. On the one hand, it can play a limiting role to limit the further insertion of the PIN pin 30, so that the PIN pin 30 is only inserted to a preset length, avoiding the PIN pin 30 from being adjusted into the accommodating space 11. On the other hand, it can also play a positioning role. The PIN pin 30 can only be inserted into the mounting hole 21 in one posture. After the PIN pin 30 is assembled into the mounting hole 21, the first contact surface 31 of the PIN pin 30 is opposite to the electrical connector 50.

[0054] Reference Figure 1 As shown, a second protrusion 14 is convexly provided on the inner wall surface of the opening 12, and the second protrusion 14 is set to deviate from the center line of the opening 12. In a feasible implementation mode, the opening 12 is a waist-shaped structure, and the second protrusion 14 is set closer to one end of the long axis direction of the opening 12. A groove is set at the corresponding position of the charging head of the external power supply. When the charging head is inserted into the opening 12 in the correct posture, the second protrusion 14 is opposite to the groove, thereby avoiding the charging head from being installed upside down. If the charging head is inserted into the opening 12 in other postures, the second protrusion 14 will interfere with the charging head. Those skilled in the art can know that the second protrusion 14 can also be set on the charging head, and a groove is set on the inner wall surface of the opening 12, which can also play a role in preventing installation errors, and is not limited here.

[0055] In the embodiments provided by the present utility model, continue to refer to Figure 1 As shown, there is a preset gap between the mounting bracket 20 and the surface of the housing 10. The value of the preset gap can be determined according to actual needs and is not limited here. By hiding the mounting bracket 20 in the housing 10, on the one hand, it can beautify the appearance, and on the other hand, it can play a shielding role to prevent the contacts on the PIN needle 30 from being exposed to the outside world, thereby causing wear, corrosion and other problems, thereby improving the charging reliability of the product.

[0056] Preferably, the shell 10 and the mounting frame 20 are integrally injection molded, and both the shell 10 and the mounting frame 20 are made of plastic, so that the shell 10 and the mounting frame 20 can meet the demand for lightweight while maintaining high strength, which not only improves the overall strength of the product, but also reduces the weight of the product, and allows the shell 10 and the mounting frame 20 to have thinner walls, thereby increasing the space inside the shell 10 and facilitating the installation of electronic components inside the shell 10.

[0057] Based on the charging PIN pin electrical connection structure provided in the above embodiments, the utility model also provides an AR glasses (not shown), the AR glasses include a frame and two temples connected to the frame, the charging PIN pin 30 electrical connection structure is arranged on the temples, the shell of the temples is the shell 10 of the charging PIN pin electrical connection structure, the AR glasses use the charging PIN pin electrical connection structure to set the first contact surface 31 of the PIN pin 30 for contacting the electrical connector 50 to a plane, when the electrical connector 50 elastically abuts against the first contact surface 31, it can have a larger contact area, thereby improving the conductive contact stability performance and the transmission stability of the charging process.

[0058] Those skilled in the art will appreciate that the charging PIN electrical connection structure can be provided not only in AR glasses, but also in a wider variety of electronic devices, including but not limited to mobile phones or smart phones, portable gaming devices, portable Internet devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, data storage devices, radios, medical equipment, vehicle transportation instruments, calculators, programmable remote controls, pagers, desktop computers, printers, other wearable devices that require charging, digital cameras, and combinations thereof, without limitation herein.
