Description

Technical Field

[0001] This utility model relates to the field of connecting wire technology, specifically to a spring-loaded fixed eyeglass charging cable. Background Technology

[0002] With the continuous development of the network communication industry, there are more and more electronic and communication products, and the demand for charging cables for these products is also increasing.

[0003] Smart glasses are a common type of smart wearable device. They combine a display system, a headphone system, and glasses to provide audio and video signal transmission while retaining the original functions of glasses.

[0004] Currently, in smart glasses, the power system is mainly located on the temples. However, to facilitate charging and simplify the structure, a new type of smart glasses has emerged that places the charging contacts on the temples, such as... Figure 8 The image shows a schematic diagram of the end of the temple of the glasses. A groove is provided on the temple, and the charging contact is located inside the groove.

[0005] Current charging devices include a spring-loaded connector that engages with charging contacts located within a recess, enabling the charging of smart glasses.

[0006] However, during the charging process, because the charging contacts and the spring pin connector are in an elastic abutting state, there is an elastic thrust between the temple and the spring pin connector, which can easily cause the connector and contacts to separate from each other, resulting in poor contact and affecting the charging effect.

[0007] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0008] The purpose of this utility model is to provide a spring-loaded, fixed-type eyeglass charging cable. To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0009] A spring-loaded eyeglass charging cable is used to charge smart glasses with charging contacts located on the temples. It includes a charging base at one end of the cable, the charging base comprising:

[0010] The base has a charging compartment for inserting the temples into it;

[0011] A conductive component is disposed at the bottom of the charging compartment and electrically connected to the wire for contacting the temple of the glasses. The conductive component includes two symmetrically arranged elastic contacts for contacting the temple of the glasses, and a clamping space is defined between the two elastic contacts for clamping the temple of the glasses.

[0012] Furthermore, the conductive component also includes a circuit board, with one end of the elastic contact soldered onto the circuit board.

[0013] Furthermore, the resilient contact foot includes:

[0014] Fixing part;

[0015] An elastic part, one end of which is formed in the fixed part, and the other end extends obliquely upward;

[0016] A protrusion is formed on the end of the elastic part and protrudes toward one end to abut against the charging contact of the temple.

[0017] The protrusions on the two elastic contact feet protrude towards each other to form the clamping space.

[0018] Furthermore, the protrusion includes a bent section, one end of which is formed at the end of the elastic portion, and the other end is bent toward another elastic contact. The end of the bent section defines an elastic contact that abuts against the charging contact.

[0019] Furthermore, the protrusion also includes an extension section that is spaced apart from and arranged side by side with the bent section, and an arc transition section is provided between the extension section and the bent section, the arc transition section defining the elastic contact point.

[0020] Furthermore, the elastic contact foot also includes two symmetrically arranged side plates, which are located on both sides of the fixing part, and each side plate includes:

[0021] A connecting portion, one end of which is formed on the fixing portion;

[0022] The sidewall portion has one end formed in the connecting portion and the other end extending along the inclined direction of the elastic portion and located beside the elastic portion. A limiting portion that bends toward the elastic portion is formed at the edge of the sidewall portion.

[0023] Furthermore, the end of the extension section is provided with a protrusion corresponding to the limiting portion, the limiting portion being used to limit the protrusion.

[0024] Furthermore, the elastic portion includes:

[0025] A horizontal segment, one end of which is formed in the fixed part and the other end extends in the horizontal direction;

[0026] An inclined segment, one end of which is formed on the horizontal segment and the other end of which extends obliquely upward, and the protrusion is formed at the end of the inclined segment.

[0027] Furthermore, a limiting plate is formed on the side plate, with the connecting portion formed on one end of the limiting plate, and the other end extending toward the horizontal section and suspended on the upper side of the horizontal section.

[0028] Furthermore, the seat body includes:

[0029] The inner shell, the charging compartment is formed on the inner shell, and the conductive component is detachably fixed at the bottom of the inner shell.

[0030] A magnetic component, wherein the magnetic component is disposed on one side wall of the inner shell;

[0031] The outer shell is injection molded onto the surface of the inner shell to cover the surface of the inner shell.

[0032] The beneficial effects of this utility model are as follows:

[0033] This utility model provides a spring-loaded eyeglass charging cable. A charging compartment for inserting the temple is provided on the charging base connected to the cable, so that the temple can abut against the elastic contacts located at the bottom of the charging compartment. At the same time, a clamping space is defined between the two elastic contacts. During the process of the temple abutting against the elastic contacts, the temple is elastically clamped within the clamping space, thereby ensuring a stable connection between the temple and the charging base and ensuring the reliability of charging.

[0034] During charging, the temple is inserted into the charging compartment, and the elastic contacts located inside the charging compartment extend into the grooves of the temple. As the temple is inserted further, the elastic contacts are pressed and deformed, ensuring close contact between the elastic contacts and the charging contacts within the grooves. Simultaneously, the elastic contacts accumulate elastic potential energy through continuous deformation. The temple, located within the clamping space, is elastically clamped by the elastic contacts. Since one end of the elastic contacts is located within the grooves of the temple, the contacts hold the temple within the charging compartment by clamping the inner wall of the groove, ensuring stability between the temple and the charging base and guaranteeing reliable charging of the smart glasses.

Detailed Implementation

[0044] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0045] This utility model embodiment provides a spring-loaded eyeglass charging cable. A charging compartment 111 for inserting a temple 500 is provided on a charging base 100 connected to the cable 600. This allows the temple 500 to abut against elastic contacts 300 located at the bottom of the charging compartment 111. Simultaneously, a clamping space 301 is defined between the two elastic contacts 300. During the abutment between the temple 500 and the elastic contacts 300, the temple 500 is elastically clamped within the clamping space 301, thereby ensuring a stable connection between the temple 500 and the charging base 100 and guaranteeing reliable charging. It is worth noting that... Figure 8 As shown, two grooves 501 are provided on the temple 500, and the charging contacts 300 on the temple 500 are located in the grooves 501. When charging, the end of the elastic contact 300 is inserted into the groove 501 and abuts against the charging contact 300 to complete the electrical connection. At this time, the elastic contact 300 is elastically compressed, thereby elastically clamping the temple 500 under the action of elastic potential energy, thus ensuring a stable connection between the temple 500 and the charging base 100.

[0046] Specifically, such as Figure 1-5 As shown, a spring-loaded eyeglass charging cable is used to charge smart glasses with charging contacts located on the temples 500. It includes a charging base 100 at one end of a wire 600. The charging base 100 includes a seat 110 and a conductive component 200 disposed within the seat 110. Specifically, the seat 110 has a charging compartment 111 for inserting the temples 500 into it. The conductive component 200 is disposed at the bottom of the charging compartment 111 and electrically connected to the wire 600, for contacting and connecting with the temples 500. The conductive component 200 includes two symmetrically arranged elastic contacts 300 for contacting the temples 500, and a clamping space 301 is defined between the two elastic contacts 300 to clamp the temples 500.

[0047] During the charging process, such as Figure 1As shown, the temple 500 is inserted into the charging compartment 111, and the elastic contact 300 located in the charging compartment 111 extends into the groove 501 of the temple 500. As the temple 500 is continuously inserted, it presses against the elastic contact 300, causing it to deform elastically. This ensures that the elastic contact 300 is in close contact with the charging contact 300 located in the groove 501. At the same time, the elastic contact 300 continuously deforms elastically, accumulating elastic potential energy. The temple 500 located in the clamping space 301 is elastically clamped by the elastic contact 300. Since one end of the elastic contact 300 is located in the groove 501 of the temple 500, during the process of elastic clamping, the elastic contact 300 clamps the temple 500 into the charging compartment 111 by clamping the inner wall of the groove 501. This ensures the stability between the temple 500 and the charging base 100 and guarantees the reliability of charging the smart glasses.

[0048] In this embodiment, the conductive component 200 further includes a circuit board 400, with one end of the elastic contact 300 soldered onto the circuit board 400. Protective circuitry can be incorporated into the circuit board 400 to improve the safety of charging the smart glasses.

[0049] like Figure 5-7 As shown, in this embodiment, the elastic contact 300 includes a fixing part 310, an elastic part 320, and a protrusion 330. The fixing part 310 is fixedly mounted on the circuit and electrically connected to the wire 600 through the circuit board 400. One end of the elastic part 320 is formed on the fixing part 310, and the other end extends obliquely upward. The protrusion 330 is formed on the end of the elastic part 320 and protrudes towards one end to abut against the charging contact of the temple 500. The protrusions 330 on the two elastic contact 300 protrude towards each other to form a clamping space 301.

[0050] In this embodiment, the elastic contact 300 is integrally formed and bent from conductive metal. The fixing part 310 is welded to the circuit board 400. The protrusion 330 is disposed on the end of the elastic part 320. The elastic part 320 is configured as an elastic plate extending obliquely upwards. When the elastic contact 300 is located within the charging compartment 111, as... Figure 3 , 5As shown, the elastic part 320 extends toward the entrance of the charging compartment 111 and tilts away from the other elastic contact 300. During the charging process of the temple 500 being inserted into the charging compartment 111, the protrusion 330 probes into the groove 501. As the temple 500 is continuously inserted, it continuously presses the elastic contact 300, thereby gradually increasing the elastic deformation of the elastic part 320 and continuously accumulating elastic potential energy. This causes the protrusion 330 to gradually and firmly contact the charging contact located in the groove 501, clamping the temple 500 and ensuring that the temple 500 is clamped in the charging compartment 111, thus ensuring the reliability of the charging process.

[0051] In this embodiment, as Figure 6-7 As shown, the protrusion 330 includes a bent section 331. One end of the bent section 331 is formed at the end of the elastic portion 320, and the other end is bent toward another elastic contact 300. The end of the bent section 331 defines an elastic contact 332 that abuts against the charging contact. The bent section 331 forms a structure that protrudes from the end of the elastic portion 320, which can be inserted into the groove 501 to abut against the charging contact. During charging, the pressure from the temple 500 causes the bent section 331 to undergo a certain elastic deformation, thereby further increasing the pressure on the charging contact and ensuring a more secure abutment between the elastic contact 332 and the charging contact.

[0052] In this embodiment, the protrusion 330 further includes an extension 333 that is spaced apart from and arranged side-by-side with the bent section 331. An arc transition portion 334 is provided between the extension 333 and the bent section 331, defining the elastic contact 332. The arc transition portion 334 between the bent section 331 and the extension 333 allows the elastic contact 332 to be defined by an arc surface. This structure allows the protrusion 330 to undergo further elastic deformation during the pressing process by the temple 500, ensuring the reliability of charging. Secondly, by setting the surface of the elastic contact 332 to an arc structure, it is possible to prevent damage to the charging contact due to its sharp end when it comes into contact with the charging contact.

[0053] In this embodiment, in order to improve the stability of the elastic contact foot 300 and prevent the elastic part 320 from tilting to the side under the pressure of the temple 500, thus causing the elastic contact foot 300 to deform, the elastic contact foot 300 also includes two symmetrically arranged side plates 340. The two side plates 340 are respectively located on both sides of the fixing part 310. By providing protection for the elastic part 320 through the side plates 340 arranged on both sides of the elastic part 320, the strength of the elastic contact foot 300 can be increased and deformation can be avoided. The two side plates 340 are symmetrically arranged and each includes a connecting part 341 and a side wall part 342. One end of the connecting part 341 is formed in the fixing part 310; one end of the side wall part 342 is formed in the connecting part 341, and the other end extends along the tilting direction of the elastic part 320 and is located on the side of the elastic part 320. A limiting part 343 that bends toward the elastic part 320 is formed at the edge of the side wall part 342.

[0054] After the smart glasses are fully charged, the temple 500 is removed from the charging compartment 111. At this time, since the protrusion 330 is located within the groove 501 and clamps the inner wall of the groove 501 under the action of elastic potential energy, a large pulling force is required when removing the temple 500 from the charging compartment 111 in order to pull the temple 500 out smoothly. At this time, since the restriction of the elastic contact 300 is suddenly released, the elastic potential energy accumulated in the elastic contact 300 is suddenly released, causing the elastic part 320 and the protrusion 330 to suddenly swing towards the other elastic contact 300. Under the action of elastic potential energy, the swing amplitude is large and the reciprocating swing is high frequency. Over time, this can easily cause deformation of the elastic part 320 and metal fatigue, thus affecting the service life of the charging cable. Therefore, a protrusion 335 corresponding to the limiting part 343 is also provided at the end of the extension 333. The limiting part 343 is used to limit the protrusion 335. After the temple 500 is removed from the charging compartment 111, the elastic part 320 is elastically reset. During the swinging process, the protrusion 335 is restricted by the limiting part 343, thereby avoiding excessive swinging amount and excessive swinging frequency of the elastic part 320, and ensuring the service life of the charging cable.

[0055] In this embodiment, the elastic portion 320 includes a horizontal section 321 and an inclined section 322. One end of the horizontal section 321 is formed on the fixed portion 310, and the other end extends horizontally. One end of the inclined section 322 is formed on the horizontal section 321, and the other end extends obliquely upward. A protrusion 330 is formed on the end of the inclined section 322. By configuring the elastic portion 320 into two parts, the deformation capacity of the elastic portion 320 can be guaranteed, and stress on the elastic portion 320 can be avoided from being concentrated at the connection between the elastic portion 320 and the fixed portion 310 during elastic deformation and elastic recovery, thereby ensuring the service life of the elastic portion 320.

[0056] Meanwhile, to further prevent excessive swing amplitude and frequency of the elastic part 320 during elastic recovery, a limiting plate 345 is formed on the side plate 340. One end of the limiting plate 345 has a connecting part 341 formed on it, and the other end extends towards the horizontal section 321 and is suspended above the horizontal section 321. When the elastic part 320 elastically recovers, the limiting plate 345 limits the amount of swing of the horizontal section 321, thereby preventing excessive swing amplitude and frequency of the elastic part 320 and ensuring the service life of the charging cable.

[0057] In this embodiment, the base 110 includes an inner shell 112, a magnetic component 113, and an outer shell 114. The charging compartment 111 is formed on the inner shell 112, and the conductive component 200 is detachably fixed to the bottom of the inner shell 112. The magnetic component 113 is disposed on one side wall of the inner shell 112. The outer shell 114 is injection molded onto the surface of the inner shell 112 to cover the surface of the inner shell 112. It is conceivable that another magnetic component is provided on the temple 500 to match the magnetic component. This allows the attraction and repulsion forces of the two magnetic components when the temple 500 is inserted into the charging compartment 111 to indicate whether the insertion direction of the temple 500 is correct, thus avoiding incorrect positive and negative polarity connections.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
