Description

Technical Field

[0001] The utility model relates to the field of data lines, in particular to a telescopic data line module with coaxial electrodes and a telescopic data line conductive structure having the same. Background Art

[0002] In the retractable data cable module, the retractable data cable module can be adaptively combined with an adapter, a socket and a vehicle-mounted charging head.

[0003] The retractable data cable module is generally provided with a fixed disk and a movable disk. The fixed disk and the movable disk are respectively provided with a first electrode portion and a second electrode portion that cooperate with each other. There are generally multiple electrode portions to meet the needs of charging and data transmission. The movable disk is used to wind the data cable, and through the contact between the first electrode portion and the second electrode portion, the coupling of the electrodes is achieved while rotating.

[0004] In the existing retractable data cable module, such as Chinese patent CN202322261314.4, the first electrode part and the second electrode part mainly realize the transmission of charging and data lines through the contact plate and the contact sheet. At that time, it was found in actual use that the metal layer of the contact plate would wear out after a period of use, thereby affecting the stability of charging (the impact on data is relatively small), resulting in poor contact problems and a short service life, which affects the user experience. Utility Model Content

[0005] The main purpose of the utility model is to propose a telescopic data line module with coaxial electrodes, aiming to improve the structure of the telescopic data line module, ensure that the first electrode part and the second electrode part of the charging end have good wear resistance, and can pass a larger current, and have low production costs and a stable structure, thereby effectively improving the service life of the module.

[0006] To achieve the above objectives, the present invention provides a retractable data line module with coaxial electrodes, comprising:

[0007] A housing, wherein the housing is provided with an inner cavity, wherein the inner cavity is provided with a pivotally arranged movable disk, and the movable disk is used for winding the data cable;

[0008] A first plate body, wherein the lower wall of the first plate body is provided with at least one set of annular electrodes, the annular electrodes are annular and can be detachably mounted on the first plate body;

[0009] The fixed disk is arranged below the moving disk. The fixed disk is provided with a contact electrode matched with the ring-shaped electrode. The contact electrode contacts the wall surface of the ring-shaped electrode.

[0010] A telescopic data line conductive structure, the above-mentioned coaxial electrode telescopic data line module, the ring-shaped electrode is provided with two groups of conductive positive electrodes and conductive negative electrodes, and the contact electrode is provided with a contact positive electrode and a contact negative electrode that match the conductive positive electrode and the conductive negative electrode.

[0011] In the actual design, the ring-shaped electrode is detachably mounted on the first plate as a separate individual, and then used as a charging end (of course it can also be used as a data end, but the current of the data end is smaller, so a larger contact area is not required). The ring-shaped electrode can be set at the axial position of the first plate or at the outer position of the first plate, so that the contact electrode can contact the inner wall or outer wall of the ring-shaped electrode, which not only ensures the stability of the contact, but also can serve as a pivot structure, thereby ensuring the relative stability of the rotation of the moving disk. Through the cooperation of the ring-shaped electrode and the contact electrode, the contact area is larger and the contact is more stable, realizing surface-to-surface contact, reducing poor contact at the charging end, and improving the stability of the data cable module.

[0028] like Figures 1 to 6 As shown, a coaxial electrode retractable data line module includes:

[0029] A housing 1 is provided with an inner cavity 2, wherein the inner cavity 2 is provided with a pivotally arranged movable disk 2, and the movable disk 2 is used for winding a data cable 22;

[0030] A first plate 31 is provided with a lower wall of the movable disk 2 and at least one set of annular electrodes 4. The annular electrodes 4 are annular and can be detachably mounted on the first plate 31.

[0031] The fixed disk 21 is provided below the movable disk 2 . The fixed disk 21 is provided with a contact electrode 5 that matches the ring electrode. The contact electrode 5 contacts the wall surface of the ring electrode 4 .

[0032] In the actual design, the ring-shaped electrode 4 is detachably mounted on the first plate 31 as a separate individual, and then used as a charging end (of course it can also be used as a data end, but the current of the data end is small, so a larger contact area is not required). The ring-shaped electrode 4 can be set at the axial position of the first plate 31 or at the outer position of the first plate 31, so that the contact electrode 5 can contact the inner wall or outer wall of the ring-shaped electrode 4, which not only ensures the stability of the contact, but also can serve as a pivot structure, thereby ensuring the relative stability of the rotation of the moving disk 2. Through the cooperation of the ring-shaped electrode 4 and the contact electrode 5, the contact area is larger and the contact is more stable, realizing surface-to-surface contact, reducing poor contact at the charging end, and improving the stability of the use of the data line 22 module.

[0033] One set of ring electrodes may consist of two ring electrodes as a single electrode (e.g., ring electrodes arranged at intervals, with the contact electrode arranged between the two ring electrodes) or a single individual as a set;

[0034] In one embodiment, the ring electrodes are preferably provided in two groups, namely the positive electrode of the power supply and the negative electrode of the power supply;

[0035] Of course, in other embodiments, a group of ring-shaped electrodes (such as the positive electrode) can also effectively support and increase the contact area, and the other group consists of springs and annular conductive rings as the negative electrode to ensure electrical connection.

[0036] The ring electrode 4 is preferably in a closed-loop circular shape. Of course, when the number of contact electrodes 5 is large, it may not be a closed-loop structure. Of course, when the contact electrodes 5 are elastic, the ring electrode 4 may not be in a circular shape to maintain electrical connection.

[0037] Specifically, the ring-shaped electrode 4 is made of copper material and has a predetermined thickness. The contact electrode 5 contacts the inner wall or outer wall of the ring-shaped electrode 4, thereby increasing the contact area, which can effectively improve the charging power and charging stability.

[0038] In the embodiment of the present invention, the first plate 31 is provided with a latching position, and the ring-shaped electrode 4 is provided with a latching portion that cooperates with the latching position. The latching portion can be inserted into the latching position and electrically connected to the first plate 31. This facilitates the installation of the ring-shaped electrode 4. Preferably, at least three latching portions are provided to ensure balanced force and reduce rotational wear.

[0039] Specifically, the contact electrode 5 includes an annular portion 501 and an elastic portion 502 extending outward from the inner circumference of the annular portion 501 or extending inward from the outer circumference of the annular portion 501. The elastic portion 502 is provided in multiple portions and contacts the sidewall of the annular electrode 4. The elastic portion 502 preferably has a certain elasticity to achieve contact with the annular electrode 4. Of course, the contact electrode 5 can also be configured as a structure similar in shape to the annular electrode 4. Correspondingly, its contact area is larger, resulting in uneven rotation and higher costs. The elastic portion 502 can also exert a predetermined pressure when in contact with the annular electrode 4, thereby achieving a damping effect on the movable disk 2 and improving the user experience.

[0040] In an embodiment of the present utility model, the annular electrode 4 is provided on the lower wall of the first plate 31, the lower wall or upper wall of the fixed disk 21 is provided with a second plate 32, the contact electrode 5 is installed on the second plate 32, the outer wall or inner wall of the annular electrode 4 forms a contact cavity, the contact electrode 5 extends into the contact cavity and fits with the wall surface of the annular electrode 4, thereby realizing rotation guidance while avoiding increasing the thickness of the module.

[0041] Specifically, the ring electrodes 4 are provided with two groups including an inner ring electrode 41 and an outer ring electrode 42. The contact electrode 5 is provided with an inner conductive seat 51 and an outer conductive seat 52 that match the inner ring electrode 41 and the outer ring electrode 42. The inner ring electrode 41 and the outer ring electrode 42 are respectively provided at the middle and outer positions of the first plate 31.

[0042] The inner conductive seat 51 is arranged in the inner cavity 2 of the inner ring electrode 41, and the outer conductive seat 52 is arranged in the outer cavity of the outer ring electrode 42, thereby realizing double guidance of the first plate 31. Compared with the structure of vertical contact, the side wall contact structure has less effect on the internal stress of the elastic part 502 and has a larger contact area.

[0043] In the embodiment of the present invention, the portion where the contact electrode contacts the ring electrode 4 is an arc-shaped surface 503 , thereby ensuring stable contact and reducing wear caused by contact.

[0044] Specifically, the first plate body 31 and the second plate body 32 are PCB boards. Of course, the specific plates can also be structures such as etched metal plates. Among them, PCB boards have the lowest production cost and are easy to process.

[0045] In the embodiment of the present invention, the second plate 32 is provided on the lower wall of the fixed disk 21 , and the contact electrode 5 passes through the fixed disk 21 and is connected to the second plate 32 , wherein the second plate 32 is used to connect to the power supply terminal.

[0046] Specifically, the upper wall of the fixed disk 21 is provided with a spring clip 61 connected to the second plate 32, and the lower wall of the first plate 31 is provided with an annular conductive ring 62 that cooperates with the spring clip 61. Multiple spring clips 61 are provided. When the charging terminal and the data terminal are respectively implemented by the contact electrode 5 and the spring clip 61, the instability problem of existing high-power charging modules can be effectively avoided, and the current flow rate can be improved. When a group of the annular electrodes is provided, the annular electrode serves as the first conductive electrode, and the spring clip and the annular conductive ring serve as the second conductive electrode.

[0047] A telescopic data line conductive structure, the above-mentioned coaxial electrode telescopic data line module, the ring-shaped electrode is provided with two groups of conductive positive electrodes and conductive negative electrodes, and the contact electrode is provided with a contact positive electrode and a contact negative electrode that match the conductive positive electrode and the conductive negative electrode.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
