[0023] 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.

[0024] like Figures 1 to 4 As shown, an embodiment of the utility model provides a charging PIN pin fixing structure, including a housing 10 and a mounting frame 20, wherein:

[0025] The shell 10 can be made of a hard material and has a receiving space 11 therein to accommodate electronic components of the electronic device such as a processor, a sensor, a battery, etc. A first surface 14 of the shell 10 is provided with an opening 12 connected to the receiving space 11, and the opening 12 connects the receiving space 11 with the outside.

[0026] 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, and the mounting frame 20 is recessed inwardly relative to the first surface 14 in the direction of the accommodating space 11. There is a preset gap between the mounting frame 20 and the first surface 14 of the outer shell 10. The value of this preset gap can be determined according to actual needs and is not limited here. By hiding the mounting frame 20 in the outer shell 10, on the one hand, the exposure of the mounting frame 20 to the appearance of the product can be reduced, thereby improving the appearance of the product. 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.

[0027] The mounting frame 20 is provided with a plurality of mounting holes 21, 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.

[0028] The plurality of PIN pins 30 are fixed in the plurality of mounting holes 21 in a one-to-one correspondence. The PIN pins 30 play the role of conducting electricity and transmitting signals. The material of the PIN pins 30 may be conductive metal or conductive ceramic, etc., which is not limited here.

[0029] Furthermore, the mounting frame 20 and the shell 10 are integrally injection molded, and the mounting frame 20 is injected onto the shell 10 by secondary injection molding or two-color injection molding, which can effectively enhance the strength, consistency and reliability of the product. The shell 10 and the mounting frame 20 are both made of plastic, so that the shell 10 and the mounting frame 20 maintain high strength while meeting the demand for lightweight. Not only can the overall strength of the product be improved, the weight of the product can also be reduced, and the shell 10 and the mounting frame 20 can have thinner wall thicknesses, thereby increasing the space inside the shell 10 and facilitating the installation of electronic components inside the shell 10.

[0030] Preferably, the melting point of the mounting frame 20 is higher than the melting point of the outer shell 10, so that the mounting frame 20 is injection molded first. In a feasible implementation, the melting point of the mounting frame 20 is approximately 15-50°C higher than that of the outer shell 10, which can effectively prevent the mounting frame 20 from melting and deforming when molding the outer shell 10, thereby ensuring the complete shape of the mounting frame 20.

[0031] Furthermore, the mounting frame 20 is made of fireproof material, which can prevent the mounting frame 20 from increasing in temperature and avoiding burning of the mounting frame 20, thereby ensuring the charging efficiency and performance of the charging structure and ensuring the service life of the product. Other components (such as the outer shell 10) can be made of non-fireproof materials, which is not limited here.

[0032] In a feasible implementation manner, the PIN needle 30 extends into the mounting hole 21 along the axial direction of the mounting hole 21, and the PIN needle 30 is vertically assembled into the mounting hole 21 from top to bottom, thereby avoiding collision and wear of the contacts on the PIN needle 30 during the installation process, thereby improving the charging reliability of the product.

[0033] Furthermore, the PIN needle 30 is fixed in the mounting hole 21 by interference fit, and the PIN needle 30 can be stably arranged in the mounting hole 21 without displacement or twisting, which facilitates the installation of the PIN needle 30 and effectively ensures the stability of the conductive contact performance.

[0034] 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 radially along the mounting hole 21.

[0035] Reference Figure 3 as well as Figure 4 As shown, the PIN needle 30 includes a first main body section 301 and a second main body section 302 connected to each other. The diameter of the first main body section 301 is smaller than the diameter of the second main body section 302. An abutment surface 31 is formed between the first main body section 301 and the second main body section 302. The abutment surface 31 is a plane extending along the radial direction of the PIN needle 30.

[0036] When the PIN pin 30 is assembled into the mounting hole 21, the abutting surface 31 presses 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. When the PIN pin 30 is inserted in other postures, the PIN pin 30 will be blocked, which will be conducive to the stable electrical connection between the charging component in the housing 10 and the PIN pin 30.

[0037] Reference Figure 1 As shown, a second protrusion 13 is convexly provided on the inner wall surface of the opening 12, and the second protrusion 13 is set deviating 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 13 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 13 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 13 will interfere with the charging head. Those skilled in the art can know that the second protrusion 13 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.

[0038] Based on the charging PIN pin fixing 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 fixing structure is arranged on the temples, and the shell of the temples is the shell 10 of the charging PIN pin fixing structure. The AR glasses use the charging PIN pin fixing structure to sink the mounting frame 20 and hide it in the opening 12 of the shell 10. On the one hand, it can reduce the exposure of the mounting frame 20 to the appearance surface of the product, thereby improving the appearance of the product. On the other hand, it can play a shielding role to prevent the contacts on the PIN pin 30 from being exposed to the outside world, thereby causing wear, corrosion and other problems, thereby improving the charging reliability of the product.

[0039] Those skilled in the art will appreciate that the charging PIN pin fixing 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 devices, vehicle transportation instruments, calculators, programmable remote controls, pagers, desktop computers, printers, other wearable devices that require charging, digital cameras, and combinations thereof, etc., without limitation herein.
