Therefore, it should not be understood as a limitation on the present application.

[0030] There is a technical problem in the related technology that the expansion dock products currently on the market require external wiring when used, resulting in clutter in the car.

[0031] In order to solve the above technical problems, the embodiment of the present application provides a vehicle-mounted retractable cable expansion dock. In the embodiment of the present application, the expansion dock is installed in a groove of the car when in use. Figure 1-4 As shown, the vehicle-mounted retractable cable expansion dock of the embodiment of the present application includes a shell, which is composed of an upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 can be fixedly connected by a snap connection or a bolt connection, which is not limited here.

[0032] A telescopic line 3, a telescopic module 4 and a PCBA board are provided in the internal space formed between the upper shell 1 and the lower shell 2. One end of the telescopic line 3 is connected to the PCBA board, wherein the PCBA board includes a first PCBA board 5 and a second PCBA board 6, the first PCBA board 5 is installed on the lower shell 2 in the shell, and the first PCBA board 5 is connected to the second PCBA board 6; the other end of the telescopic line 3 is wound around the telescopic module 4 and extends out of the shell. Under the action of the telescopic module 4, the telescopic line 3 can control the pull-out length and automatic recovery of the telescopic line 3. A conductive ejector pin 7 is provided at the front end of the lower shell 2, and the conductive ejector pin 7 is connected to the PCBA board and the car, and can supply power to the product and transmit data. Preferably, the conductive ejector pin 7 can be designed with 2 or more ejector pin interfaces.

[0033] The telescopic module 4 includes a cable clamping disk 41, a spring 42 and a clamping disk structure 43. After the other end of the telescopic cable 3 is wound on the cable clamping disk 41, its interface extends out of the housing. The cable clamping disk 41 is provided with a spring 42, which is used to rebound to drive the cable clamping disk 41 to rotate and retract the telescopic cable 3. The clamping disk structure 43 is located on one side of the cable clamping disk 41 and is used to restrict or release the cable clamping disk 41. Preferably, the interface of the telescopic cable 3 is Type-C, Micro USB or Lightening or other adapters.

[0034] When external force pulls out the telescopic wire 3, the wire clamping disc 41 rotates to release the telescopic wire 3. The clockwork spring 42 is in a tensioned state during this process to accumulate elastic force. The chuck structure 43 can control the desired fixed position of the telescopic wire 3. When the telescopic wire 3 needs to be retracted, the telescopic wire 3 is pulled, the chuck structure 43 releases the wire clamping disc 41, the clockwork spring 42 rebounds, the wire clamping disc 41 flips over, and the telescopic wire 3 is retracted to the wire clamping disc 41.

[0035] The second PCBA board 6 is provided with a contact sheet (not shown in the figure) connected to the first PCBA board 5. The second PCBA board 6 is fixed on the clamping plate 41. The PCBA board can be designed with a circuit to control the power. When the product is fixed, the conductive ejector pin 7 is connected to the car to provide power to the product and transmit data.

[0036] When the product needs to be charged, the retractable cord 3 can be pulled out for charging, and when the retractable cord 3 is used up, it can be retracted into the cord holder 41 of the retractable module 4 .

[0037] It should be noted that the telescopic module is a prior art, and the wire clamping disk, clockwork spring and clamping disk structure involved therein can all adopt the telescopic structure disclosed in patent publication number CN117566545A and patent name "A Telescopic Wire Device", which will not be repeated here.

[0038] In addition, a telescopic wire joint accommodating groove (not shown in the figure) is provided on the outside of the shell, and the joint at one end of the telescopic wire 3 extending out of the shell matches the shape of the telescopic wire joint accommodating groove, so that the joint can be installed just in the accommodating groove, and the joint of the telescopic wire 3 extending out of the shell is fixed to the outer wall of the shell by magnetic attraction, so that after the telescopic wire 3 is retracted, the joint of the telescopic wire 3 will not swing randomly due to extension.

[0039] Furthermore, in order to achieve the fixation between the entire expansion dock and the automobile groove, a cover-opening magnet 8 is provided on the inner side of the front end of the shell, and the cover-opening magnet 8 is attracted to the magnet inside the automobile groove cover, and is used to open the automobile groove cover. In addition, a thrust pin 9 is also provided at the front end of the shell, and a first spring 10 is provided inside the thrust pin 9, and the other end of the first spring 10 away from the thrust pin 9 abuts against the shell (not shown in the figure). When the product is close to the automobile groove cover, the cover-opening magnet 8 is attracted to the magnet of the automobile groove cover, the automobile groove cover opens, and the expansion dock as a whole can be pushed into the automobile groove. Since the thrust pin 9 is provided with the first spring 10, the first spring 10 is squeezed and accumulates elastic force during the process of being pressed inward.

[0040] In addition, grooves 11 are provided on both sides of the shell, and a ejection block 12 is provided on the shell in the groove 11. The ejection block 12 is adapted to the elastic movable protrusions on both sides of the automobile groove. A second spring 13 is provided in the ejection block 12. The other end of the second spring 13 away from the ejection block 12 abuts against the shell (not shown in the figure), and the elastic force of the second spring 13 is less than the elastic force of the movable protrusion. When the expansion dock is pressed inwardly into the automobile groove, the automobile protrusion is clamped in the groove 11, and the entire expansion dock is fixed in the automobile groove. In this process, the ejection block 12 is provided with a second spring 13, and the second spring 13 is squeezed to accumulate elastic force.

[0041] The rear end of the housing is also provided with an opening button 14, and a connecting rod assembly 15 is provided inside the housing. The opening button 14 is linked to the ejection block 12 through the connecting rod assembly 15, and the opening button 14 drives the connecting rod assembly 15 to drive the ejection block 12 outward. When the product needs to be replaced, the opening button 14 is pressed, and the opening button 14 pushes the connecting rod assembly 15 to move, and the connecting rod assembly 15 pushes the ejection block 12 outward. Under the elastic force of the second spring 13, the ejection block 12 ejects the automobile protrusion, and at the same time, under the elastic force of the first spring 10, the expansion dock is ejected, and the expansion dock can be taken out for product replacement.

[0042] Specifically, the open button 14 includes a pressing portion 141 and a driving portion 142 connected to each other. The pressing portion 141 is preferably an elliptical block structure, and the driving portion 142 is preferably a triangular block structure. The pressing portion 141 is located outside the shell, and the driving portion 142 is located inside the shell.

[0043] The connecting rod assembly 15 includes a first pushing portion 151, a second pushing portion 152 and a connecting rod 153. The connecting rod 153 is two columnar rods, preferably cylindrical rods; one end of the first pushing portion 151 is connected to the connecting rod 153, and the other end is connected to the ejection block 12 on one side of the shell; one end of the second pushing portion 152 is connected to the connecting rod 153, and the other end is connected to the ejection block 12 on the other side of the shell; the connecting rod 153 includes two columnar rods movably arranged on the shell, and a driving member in a triangular block structure is located between the two columnar rods. Under the action of the driving portion 142, the connecting rod 153 expands outward and links the first pushing portion 151 and the second pushing portion 152 to respectively push the two ejection blocks 12 outward.

[0044] More specifically, the driving portion 142 is a triangular block structure; the first pushing portion 151 is an L-shaped plate structure, and the second pushing portion 152 is a straight rod structure; the triangular block structure is located between the two columnar rods, and the two columnar rods are pushed forward by pushing the triangular block structure forward.

[0045] Preferably, the two columnar rods can be directional movable, which can be achieved by providing directional sliding grooves on the housing (not shown in the figure).

[0046] When the product needs to be replaced, the pressing part 141 of the open button 14 is pressed to push the driving part 142 to move inward. Since the driving part 142 is a triangular block structure, the two cylindrical rods are pushed to move to both sides of the moving direction during the forward movement of the triangular block structure, thereby driving the pushing part to push the ejection block 12 outward.

[0047] In addition, a third spring 143 is provided at one end of the driving portion 142 away from the pressing portion. During the above-mentioned inward movement, the third spring 143 is squeezed to accumulate elastic force to help the opening button 14 to rebound.

[0048] Finally, it should be noted that since the present application does not involve any changes related to the automobile, the above-mentioned automobile-related components that are compatible with the expansion dock of the present application are not shown in the figures.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
