[0028] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "connected", "connected" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0029] The present application provides a docking station 100, please refer to Figure 1 、 Figure 5 and Figure 6 , the docking station 100 is used for connecting to the vehicle interface 301 of the vehicle host, and the vehicle interface 301 is exposed on the vehicle panel 302. The vehicle interface 301 can be a USB (Universal Serial Bus, Universal Serial Bus) interface, and the USB interface type includes but is not limited to Type-A or Type-C and the like, and the vehicle host can supply power to the external device or exchange data with the external device through the vehicle interface 301.

[0030] Please refer to Figure 2 and Figure 4 , the docking station 100 includes an adapter 10, a main body 20 and a wire 30. The adapter 10 includes an adapter interface 11, and the adapter interface 11 is used for plugging with the vehicle interface 301 and establishing a conductive path. Exemplarily, the vehicle interface 301 is a female interface, the adapter interface 11 is a male interface, and the adapter interface 11 is inserted into the vehicle interface 301.

[0031] The main body 20 includes a shell 21, a power module 22 (not shown in the figure) and at least one electrical interface 23. The power module 22 is arranged in the shell 21, the electrical interface 23 is exposed outside the shell 21 and is electrically connected with the power module 22, the electrical interface 23 is used for plugging with the interface of the mobile terminal, and the wire 30 connects the adapter 10 and the power module 22. In this way, the mobile terminal and the vehicle interface 301 are electrically connected, and the power module 22 is used for converting the output current of the vehicle interface 301 into the input current of the interface of the mobile terminal to supply power to the mobile terminal. Therefore, the docking station 100 can realize connecting the mobile terminal to the vehicle interface 301 and charging. Exemplarily, the number of electrical interfaces 23 is at least two, so that the docking station 100 can expand the vehicle interface 301 into a plurality of electrical interfaces 23 for charging.

[0032] The mobile terminal includes but is not limited to a mobile phone, a driving recorder, a mobile power supply and the like.

[0033] The electric interface 23 can be in the form of a female interface or a male interface. In an exemplary embodiment where the electric interface 23 is a female interface, the mobile terminal can achieve the electric connection with the electric interface 23 by inserting the interface of the power line adapted by the mobile terminal into the electric interface 23; in an exemplary embodiment where the electric interface 23 is a male interface, the electric interface 23 can be directly inserted into the interface of the mobile terminal to achieve the electric connection between the two.

[0034] Of course, other modules can also be configured in the main body 20 of the docking station 100 to achieve more functions. For example, the main body 20 comprises a data module and a card slot for accessing a storage card or other storage medium, the card slot is electrically connected with the data module, and the data module is connected with the electric line 30 to achieve the data exchange between the storage medium and the vehicle interface 301.

[0035] Please refer to Figure 2 and Figure 3 The electric line 30 is flexible, i.e. the electric line 30 can be freely bent and coiled to enable the adapter 10 to move freely relative to the main body 20. For example, the electric line 30 can be a USB data line. The shell 21 comprises a mounting structure 40 for connecting with the vehicle panel 302 to fix the docking station 100 to the vehicle panel 302.

[0036] In the related art, some docking station 100 products have a relatively large size, while the vehicle interface 301 has a relatively small size and is located in a relatively hidden position. When installing the docking station 100, the docking interface 11 of the docking station 100 is difficult to be aligned with the vehicle interface 301 due to the blocked line of sight. The docking station 100 provided in the embodiments of the present application does not need to move the entire docking station 100 at one time, but can first insert the adapter 10 into the vehicle interface 301, and then move the main body 20 to connect the mounting structure 40 to the vehicle panel 302, so that the docking station 100 can be conveniently and quickly installed and fixed to the vehicle panel 302, thereby improving the user experience.

[0037] It should be noted that the vehicle panel 302 can be the side wall surface of the hollow space below the auxiliary instrument panel, the outer wall surface of the central armrest box 200, or the decorative plate surface below the automobile center console. The docking station 100 provided in the embodiments of the present application can solve the problem of the inconvenience of installing the docking station 100 in these positions, and can be adapted to the positions of various vehicle panels 302.

[0038] In some embodiments, please refer to Figure 4The shell 21 comprises a first side wall 211, which is used to cooperate with the vehicle panel 302, i.e. the shape of the first side wall 211 is adapted to the shape of the vehicle panel 302. For example, the shape of the vehicle panel 302 is arc-shaped, and the shape of the first side wall 211 is correspondingly arc-shaped and can be attached to the vehicle panel 302. The mounting structure 40 comprises an adhesive strip, which is arranged on the first side wall 211 and used to bond the main body 20 to the vehicle panel 302, so as to bond and fix the docking station 100 to the vehicle panel 302. The adhesive mounting method does not need to punch holes and is simple to install.

[0039] For example, in an embodiment, the number of adhesive strips is one, and the adhesive strip is arranged around the circumferential edge of the first side wall 211. For example, in another embodiment, the number of adhesive strips is multiple, and the multiple adhesive strips are arranged at intervals around the circumferential edge of the first side wall 211, as shown in Figure 2 .

[0040] In some embodiments, referring to Figure 4 , the main body 20 comprises a charging wire 24, which comprises a first end and a second end. The first end of the charging wire 24 is arranged in the shell 21 and establishes an electrically conductive path with the power supply module 22. The shell 21 has a through hole, and the charging wire 24 passes through the through hole. The electric interface 23 is located outside the shell 21 and arranged at the second end of the charging wire 24. The charging wire 24 leads the electric interface 23 out of the external space of the shell 21, and the electric interface 23 can be pulled to a designated position according to the needs of the user and connected with the interface of the mobile terminal. In this way, the user does not need to prepare an appropriate power line and does not need to search for a suitable position to plug in the electric interface 23 and place the mobile terminal every time the user uses the electric interface 23 of the docking station 100, and the docking station 100 is more convenient to use.

[0041] In some embodiments, referring to Figure 4 , the docking station 100 comprises a storage disc 50 and an elastic member (not shown in the figure). The storage disc 50 is arranged rotatably in the interior of the shell 21 and used to wind the charging wire 24. The elastic member is used to apply an elastic force to the storage disc 50, so that the storage disc 50 has a tendency to rotate in the direction of winding the charging wire 24. When the user needs to use the electric interface 23 of the docking station 100, the charging wire 24 is pulled out, at which time the storage disc 50 is relaxed and the elastic member is elastically deformed. When the user does not need to use it, the charging wire 24 is loosened from the mobile terminal, at which time the elastic member restores the elastic deformation, the storage disc 50 rotates in the direction of winding the charging wire 24, the length of the charging wire 24 extending out of the shell 21 is shortened, and most of the charging wire 24 is retracted into the shell 21. In this way, the storage performance of the docking station 100 is good and does not excessively affect the aesthetic appearance of the vehicle interior.

[0042] It should be noted that the elastic member can be in the form of a coil spring or an elastic rope.

[0043] In some embodiments, referring to Figure 4 , a part of the first side wall 211 is recessed towards the inside of the shell 21 to form a mounting groove 21A, and the adapter 10 is detachably accommodated in the mounting groove 21A. It can be understood that when the docking station 100 is installed, the adapter 10 is separated from the mounting groove 21A; when the docking station 100 is installed in place, the adapter 10 is accommodated in the mounting groove 21A, and the main body 20 covers the adapter 10. On the one hand, the mounting groove 21A makes the adapter 10 not interfere with the connection between the first side wall 211 and the vehicle panel 302, and on the other hand, it can improve the appearance after the docking station 100 is installed in place.

[0044] Exemplarily, the peripheral side size of the mounting groove 21A is greater than the peripheral side size of the adapter 10, and the peripheral side of the mounting groove 21A is in clearance fit with the peripheral side of the adapter 10, which is beneficial to quickly align the mounting groove 21A with the adapter 10 and press down when moving the main body 20, and accommodate the adapter 10 in the mounting groove 21A.

[0045] Exemplarily, the edge of the side of the adapter 10 close to the inside of the main body 20 is chamfered, which is beneficial to quickly align the mounting groove 21A with the adapter 10 and press down.

[0046] In some embodiments, referring to Figure 4 , a part of the first side wall 211 is recessed towards the inside of the shell 21 to form a wiring groove 21B and a communication port 21a, the communication port 21a communicates the wiring groove 21B and the mounting groove 21A, and the electric wire 30 is arranged in the wiring groove 21B and the communication port 21a. When the docking station 100 is installed in place, the wiring groove 21B is used to accommodate the electric wire 30, so that it is not exposed to the user's field of view, improves the appearance after the docking station 100 is installed, and can avoid the problem that the electric wire 30 interferes with the first side wall 211 to cause the first side wall 211 to be difficult to fit the vehicle panel 302.

[0047] In some embodiments, referring to Figure 4 , the wiring groove 21B includes a groove side wall 2111 and a groove bottom wall 2112, and a first opening 21B1 is formed on the side of the wiring groove 21B facing the vehicle panel 302, and the groove bottom wall 2112 faces the first opening 21B1. It can be understood that when the docking station 100 is installed, the electric wire 30 is accommodated in the wiring groove 21B through the first opening 21B1.

[0048] The groove side wall 2111 is provided with a through port 21b, which communicates the wiring groove 21B and the inside space of the shell 21, and the electric wire 30 passes through the through port 21b and the communication port 21a, so that the electric wire 30 is completely located in the wiring groove 21B.

[0049] In some embodiments, referring to Figure 4The second opening 21B2 is formed on the side of the wiring slot 21B away from the mounting slot 21A, and the partial slot side wall 2111 faces the second opening 21B2. The first opening 21B1 is adjacent to and communicates with the second opening 21B2. In this way, the material can be saved and the manufacturing of the shell 21 is facilitated. It can be understood that, after the docking station 100 is installed in place, no closed space is defined between the wiring slot 21B and the vehicle panel 302.

[0050] The slot bottom wall 2112 is provided with a heat dissipation hole 2112a. The heat generated by the electronic components such as the power module 22 in the shell 21 can be dissipated out of the shell 21 through the heat dissipation hole 2112a, and out of the main body 20 through the second opening 21B2. The heat dissipation hole 2112a is arranged on the slot bottom wall 2112, which is relatively concealed, so that the docking station 100 has better aesthetics after installation.

[0051] In some embodiments, referring to Figure 4 The adapter 10 includes a support seat 12, and the adapter port 11 is arranged on the support seat 12. The support seat 12 has a glue piece 13 on one side surface, and the glue piece 13 is used to bond with the vehicle panel 302, so as to fix the adapter 10 to the vehicle panel 302. The adapter 10 is fixed relative to the vehicle panel 302 through the glue piece 13. The glue piece 13 can disperse the load borne by the vehicle-mounted adapter, so that the plug-in of the adapter port 11 and the vehicle-mounted interface 301 is more stable, the probability of poor contact between the adapter port 11 and the vehicle-mounted interface 301 caused by shaking of the vehicle during driving is reduced, the probability of deformation of the vehicle-mounted interface 301 caused by excessive stress is reduced, and the working reliability of the docking station 100 is improved.

[0052] It should be noted that, in the embodiment in which the first side wall 211 is partially recessed towards the inside of the shell 21 to form the mounting slot 21A, the adapter 10 extends into the mounting slot 21A. The peripheral side of the adapter 10 is in transition fit with the peripheral side of the mounting slot 21A, and the shell 21 can be supported by the peripheral side of the adapter 10, that is, the shell 21 is supported on the peripheral side of the adapter 10. Alternatively, the peripheral side of the adapter 10 is in clearance fit with the peripheral side of the mounting slot 21A, and the shell 21 is not supported on the peripheral side of the adapter 10.

[0053] In some embodiments, referring to Figure 4 The main body 20 includes a first magnetic attraction structure (not shown), and the adapter 10 includes a second magnetic attraction structure 14. The first magnetic attraction structure and the second magnetic attraction structure 14 are in magnetic attraction fit, so that the connection between the main body 20 and the adapter 10 is more stable and less likely to shake. The first magnetic attraction structure and the second magnetic attraction structure 14 can both be permanent magnets, or one of them can be a permanent magnet and the other can be a ferromagnetic body.

[0054] In the embodiment in which the first side wall 211 is locally recessed towards the interior of the housing 21 to form the mounting slot 21A, the first magnetic attraction structure and the second magnetic attraction structure 14 magnetically attract each other with a positioning effect. When the user installs the docking station 100, the user moves the main body 20 to align the mounting slot 21A with the adapter 10. When the first magnetic attraction structure and the second magnetic attraction structure 14 are closer to each other, the magnetic attraction force between them is stronger. The user can quickly position the spatial position of the mounting slot 21A by feeling, and then press the main body 20 down.

[0055] Exemplarily, the first magnetic attraction structure is two ferromagnetic bodies, and the second magnetic attraction structure 14 is two permanent magnets. The two permanent magnets are arranged at intervals on the adapter 10. When the docking station 100 is installed in place, the ferromagnetic bodies and the permanent magnets magnetically attract each other correspondingly.
