The contents related to the orientation of the structures of each part in this manual are only presented as examples and should not be regarded as restrictive statements.

[0028] The utility model provides a vehicle-mounted expansion dock, comprising an expansion dock 1 and a mobile device holder 2, wherein the expansion dock 1 is installed on the vehicle roof, a plurality of interfaces 01 are provided on the expansion dock 1, and the mobile device holder 2 is detachably connected to the expansion dock 1, and the mobile device holder 2 is used for detachably installing a mobile device.

[0029] Combination Figure 1 and Figure 2As shown, the docking station 1 in this embodiment is installed on the roof of the vehicle (the roof of the vehicle is not shown in the figure), and the mobile device holder 2 is detachably connected to the bottom end of the docking station 1 (i.e., the end opposite to the Z axis in the figure). The mobile device holder 2 and the docking station 1 can be detachable by any means such as snap connection, clamping, threaded connection, etc. The mobile device holder 2 and the mobile device can also be detachable by any means. For example, the more common mobile phone holder among the mobile device holders usually uses a spring clamping mechanism to clamp the mobile phone. The user can manually open the spring clamping mechanism to remove the mobile phone. The specific structure for realizing the detachable function is not limited here. The multiple interfaces 01 on the docking station 1 can be the same type of connection ports or different types of connection ports, such as various connection ports such as USB2.0, USB3.0, Type-C, etc. commonly used in the relevant technology. There is no specific limitation here. In addition, the interface 01 can be connected to the vehicle computer and / or the power management system to realize functions such as transferring files between the mobile phone and the vehicle computer, charging the tablet computer through the interface 01, etc. The interface 01 can be connected to any system on the vehicle as needed to realize related functions.

[0030] On the vehicle-mounted expansion dock in the utility model, the expansion dock 1 installed on the vehicle roof and the mobile device holder 2 are integrated together, and a plurality of interfaces 01 are provided on the expansion dock 1, and the number and type of interfaces 01 can be selected according to needs, thereby increasing the number and type of interfaces in the vehicle, meeting the interface requirements of a large number and variety of mobile devices, and having high compatibility; at the same time, the mobile device holder 2 is detachably connected to the expansion dock 1, and the mobile device is detachably installed on the mobile device holder 2. The user can remove the mobile device holder 2 and place it at other locations in the vehicle according to their own needs, or move the mobile device holder 2 from other locations to the expansion dock 1 and detachably connect it to the expansion dock 1, so that the mobile device is convenient to approach the expansion dock 1, and convenience is provided for the mobile device to charge or transmit data through the interface 01, etc., thereby improving the convenience and comfort of using the mobile device in the vehicle.

[0031] Furthermore, the expansion dock 1 is connected to a connecting device 3, the connecting device 3 includes a conical sleeve 31, a plurality of limiting balls 311 arranged in a ring shape are provided in the conical sleeve 31, and a locking rod 21 is provided on the mobile device bracket 2, the locking rod 21 is used to be inserted into the conical sleeve 31 so that the limiting balls 311 are close to each other along the inner wall of the conical sleeve 31 and clamp the locking rod 21.

[0032] Combination Figure 2As shown, a connecting device 3 is fixedly installed on the expansion dock 1, and the connecting device 3 includes a conical sleeve 31. The conical sleeve 31 is similar to a sleeve structure, and has an inner cavity connected at both ends. The inner wall of the conical sleeve 31 has a conical surface. In this embodiment, three limiting balls 311 arranged in a ring are provided in the conical sleeve 31. The three limiting balls 311 can move along the inner wall of the conical sleeve 31. When the three limiting balls 311 move along the inner wall of the conical sleeve 31 toward the positive direction of the Z axis, the three limiting balls 311 move away from each other. When the three limiting balls 311 move along the inner wall of the conical sleeve 31 toward the Z axis in the opposite direction, the three limiting balls 311 move toward each other.

[0033] Combination Figures 3 to 5 As shown, the mobile device holder 2 is provided with a locking rod 21, which can be inserted into the inner cavity of the conical sleeve 31 (an avoidance through hole can be opened at the corresponding position of the expansion dock 1 to allow the locking rod 21 to pass through and be inserted into the conical sleeve 31). In the initial state, the limiting balls 311 are located on the inner wall of the conical sleeve 31 near the end opposite to the Z axis, and the distance between the three limiting balls 311 is the minimum value. Figure 5 As shown, the locking rod 21 is inserted into the tapered sleeve 31, and the locking rod 21 pushes the three limiting balls 311 to move in the positive direction of the Z axis, so that the limiting balls 311 are separated from each other until the locking rod 21 can be inserted into the center of the three limiting balls 311. Figure 4 As shown, the three stop balls 311 tend to move toward each other due to their own weight or other external forces in the opposite direction of the Z axis (for example, a spring can apply a force in the opposite direction of the Z axis), and are also restricted by the inner wall of the tapered sleeve 31, thus clamping and fixing the locking rod 21, thereby realizing a detachable connection between the mobile device bracket 2 and the docking station 1. Figure 4 As shown, at this time, the mobile device holder 2 and the expansion dock 1 are detachably connected together. When the mobile device holder 2 needs to be removed, the limiting ball 311 can be manually moved, or a force in the positive direction of the Z axis can be applied to the limiting ball 311 through other structures (the electromagnet 371 is used as an example to apply the positive force of the Z axis in the figure, and its specific principle is described in detail later), so that the limiting ball 311 moves along the inner wall of the tapered sleeve 31 in the positive direction of the Z axis and moves away from each other, thereby releasing the locking rod 21.

[0034] In this way, the plurality of limiting balls 311 are arranged in an annular shape in the tapered sleeve 31. On the one hand, the locking rod 21 can be inserted into the tapered sleeve 31, pushing the limiting balls 311 and making the limiting balls 311 move away from each other first, so that the locking rod 21 is inserted into the space in the center of the plurality of limiting balls 311. The plurality of limiting balls 311, due to their own weight or other external forces and restricted by the inner wall of the tapered sleeve 31, will clamp the locking rod 21. On the other hand, the limiting balls 311 are manually moved or other external forces are applied to make the limiting balls 311 move along the inner wall of the tapered sleeve 31. The walls move away from each other, so that the limiting ball 311 releases the locking rod 21; the detachable connection between the mobile device holder 2 and the expansion dock 1 is realized by the connecting device 3, the assembly and disassembly process is relatively convenient, and no damage is caused to the expansion dock 1 and the mobile device holder 2. When the user needs to use the expansion dock 1 and the mobile device holder 2 at the same time in the car, the two can be detachably connected, and when the mobile device holder 2 needs to be used alone, it can be removed, which provides convenience for the user to use the mobile device in the car and improves the comfort of the user when using the mobile device in the car.

[0035] Furthermore, the connecting device 3 also includes a first shell 32 and a second shell 33, the first shell 32 and the second shell 33 are snap-fitted to form an installation cavity, the conical sleeve 31 is arranged in the installation cavity, the top end of the conical sleeve 31 abuts against the first shell 32, and the bottom end of the conical sleeve 31 abuts against the second shell 33.

[0036] Combination Figures 2 to 5 As shown, the first shell 32 and the second shell 33 are interlocked and connected (the two can be fixed to each other by means of snap connection, screw connection, etc. to ensure the stability of the connection) to form an installation cavity. The tapered sleeve 31 can be fixed in the installation cavity by means of snap connection, screw connection, etc. In this embodiment, a step portion 321 is provided on the inner wall of the first shell 32, and the step portion 321 is used to abut and limit the end of the tapered sleeve 31 along the positive direction of the Z axis (i.e., the top end), and the inner wall of the second shell 33 is used to abut and limit the end of the tapered sleeve 31 along the reverse direction of the Z axis (i.e., the bottom end).

[0037] In this way, an installation cavity is formed by the first shell 32 and the second shell 33, which plays a protective role and limits the top and bottom ends of the tapered sleeve 31 to ensure that the tapered sleeve 31 is fixed so that the limiting ball 311 can achieve clamping and loosening actions.

[0038] Furthermore, the connecting device 3 further comprises a limiting sleeve 34 , and a through hole 341 corresponding to the limiting ball 311 is provided on the limiting sleeve 34 . The limiting ball 311 contacts the inner wall of the conical sleeve 31 after passing through the through hole 341 .

[0039] Combination Figures 2 to 5As shown, a through hole 341 is provided on the limiting sleeve 34. Usually, the aperture of the through hole 341 should be slightly smaller than the diameter of the limiting ball 311, so that the limiting ball 311 can pass through the through hole 341 and contact the inner wall of the conical sleeve 31, while at the same time preventing the limiting ball 311 from completely passing through the through hole 341, which is equivalent to limiting the limiting ball 311 to a certain extent through the through hole 341. When the limiting ball 311 moves forward or reversely along the Z-axis, it will also drive the limiting sleeve 34 to move together to ensure that the plurality of limiting balls 311 maintain a circular arrangement.

[0040] The limiting sleeve 34 is usually a sleeve structure, in which the hollow inner cavity can allow the locking rod 21 to be inserted so that the locking rod 21 is located at the center of multiple limiting balls 311 and is clamped by the limiting balls 311. There is no restriction on the shape of the limiting sleeve 34 here, as long as it can play a certain limiting role on the limiting balls 311 through the through holes 341.

[0041] In this way, the through hole 341 provided on the limiting sleeve 34 can play a certain limiting role on the limiting balls 311, ensuring that the plurality of limiting balls 311 are arranged in a ring shape, and can normally realize the clamping action and the loosening action.

[0042] Furthermore, the connecting device 3 further includes an elastic member 35 and a blocking cover 36 , wherein the elastic member 35 is connected between the first housing 32 and the blocking cover 36 to drive the blocking cover 36 to abut against the limiting ball 311 .

[0043] Combination Figures 2 to 5 As shown, the elastic member 35 is a spring, which is arranged between the blocking cover 36 and the first shell 32. When the limiting ball 311 is driven by an external force to move in the positive direction of the Z axis, the elastic member 35 is compressed and accumulates potential energy. After the external force applied to the limiting ball 311 is not sufficient to overcome the elastic force of the elastic member 35, the potential energy of the elastic member 35 is converted into kinetic energy, driving the limiting ball 311 to move in the opposite direction of the Z axis, thereby driving the blocking cover 36 through the elastic member 35 and then driving the limiting ball 311 to achieve a clamping action.

[0044] In this way, by setting the elastic member 35 , the blocking cover 36 can be driven to drive the limiting balls 311 to move closer to each other to achieve a clamping action, thereby improving the clamping firmness of the limiting balls 311 on the locking rod 21 .

[0045] Furthermore, the connecting device 3 further comprises an electromagnet assembly 37 , which is mounted on the first housing 32 to drive the limiting balls 311 to move away from each other along the inner wall of the tapered sleeve 31 and release the locking rod 21 .

[0046] Combination Figures 2 to 5As shown, the electromagnet assembly 37 is fixedly mounted on the first housing 32, and is arranged corresponding to the position of the elastic member 35 at one end along the positive direction of the Z axis. When the electromagnet assembly 37 is energized to generate magnetic force, it can generate an attraction force in the positive direction of the Z axis to the limiting ball 311 (the limiting ball 311 is made of a magnetic material, such as iron), thereby driving the limiting ball 311 to move away from each other along the inner wall of the tapered sleeve 31 to achieve a loosening action. Optionally, the plugging cover 36 and the tapered sleeve 31 can both be made of a magnetic material to provide a sufficient magnetic force.

[0047] In this way, when the limiting ball 311 needs to be released, the magnetic attraction of the electromagnet assembly 37 is controlled to control the limiting ball 311 to release the limiting ball 311, so that the mobile device bracket 2 and the expansion dock 1 can be disassembled more conveniently.

[0048] Furthermore, the electromagnet assembly 37 includes an electromagnet 371, a controller 372 and a control switch 373, the control switch 373 and the controller 372 are installed on the expansion dock 1, the electromagnet 371 is installed on the first shell 32, and the control switch 373 and the electromagnet 371 are electrically connected to the controller 372 respectively.

[0049] Combination Figure 2 As shown, the electromagnet 371 is installed on the first shell 32, and the controller 372 and the control switch 373 are installed on the expansion dock 1, wherein the control switch 373 can be in the form of a button, touch, etc., and is set on the outer surface of the expansion dock 1 for the user to touch directly. When the user uses the control switch 373, the controller 372 will control the electromagnet 371 to generate a magnetic attraction force on the limiting ball 311, thereby realizing the release action of the limiting ball 311.

[0050] In this way, the release action of the limit ball 311 is controlled by controlling the switch 373, the controller 372 and the electromagnet 371, and the user can conveniently operate to disassemble the mobile device holder 2 and the expansion dock 1 in the car.

[0051] Furthermore, the limiting sleeve 34 is a conical shape matching the conical sleeve 31 .

[0052] Combination Figures 2 to 5 As shown, the limiting sleeve 34 is conical in shape and matches the conical sleeve 31. When the limiting sleeve 34 is located in the conical sleeve 31, the limiting sleeve 34 can better limit the limiting ball 311 without affecting the contact between the limiting ball 311 and the inner wall of the conical sleeve 31.

[0053] Furthermore, a protrusion 211 is provided at one end of the locking rod 21 away from the mobile device bracket 2 , and the limiting ball 311 clamps the locking rod 21 to engage with the protrusion 211 .

[0054] Combination Figure 2 , Figure 4 and Figure 5 As shown, a protrusion 211 is provided at one end of the locking rod 21 away from the mobile device bracket 2. The diameter of the protrusion 211 is larger than that of the locking rod 21. The protrusion 211 can also be designed as a ball head shape. When the locking rod 21 is inserted into the tapered sleeve 31, the protrusion 211 first pushes the limiting ball 311 to move in the positive direction of the Z axis and move away from each other until the protrusion 211 can pass through the center of the limiting ball 311. The limiting ball 311 is moved in the opposite direction of the Z axis and moves towards each other due to its own weight or other external forces, thereby clamping the locking rod 21. At this time, the protrusion 211 A clamping relationship is formed between 11 and the limiting ball 311. Even if the limiting ball 311 fails to clamp the locking rod 21, the protrusion 211 will still be pressed against the limiting ball 311 in the reverse direction of the Z-axis, so that the limiting balls 311 will not move away from each other. When the mobile device holder 2 and the expansion dock 1 need to be disassembled, the limiting balls 311 can be moved in the positive direction of the Z-axis and away from each other by manual manipulation or other external forces (such as the magnetic attraction of the electromagnet mentioned above), thereby loosening the locking rod 21 and allowing the protrusion 211 to pass through the center of multiple limiting balls 311 in the reverse direction.

[0055] In this way, by providing a protrusion 211 on the locking rod 21, the reliability of the detachable connection between the expansion dock 1 and the mobile device holder 2 is improved, ensuring that the expansion dock 1 and the mobile device holder 2 will not be accidentally detached, thereby improving the user experience of using the expansion dock 1 and the mobile device holder 2.

[0056] Furthermore, the vehicle roof includes a roof beam located on the top of the vehicle, and the docking station 1 includes a decorative cover 11 and a frame 12, wherein the frame 12 is used to be installed on the roof beam, and the decorative cover 11 is installed on the frame 12. Figure 2 and Figure 3 As shown, the frame 12 is usually made of sheet metal, which is provided with a through hole for passing the line of the interface 01 or other device structure, and the connecting device 3 can be installed on the frame 12 by means of bolts, etc. The decorative cover 11 covers at least part of the frame 12 and the connecting device 3 and other structures, and the decorative cover 11 is provided with a connecting through hole so that the locking rod 21 can pass through the connecting through hole and enter the tapered sleeve 31. The frame 12 can be welded and fixed on the top cover crossbeam (the top cover crossbeam is not shown in the figure), and the decorative cover 11 and the frame 12 are usually provided with buckles and slots to connect the two to each other and install them, and the specific installation method is not limited here.

[0057] In this way, the skeleton 12 is installed on the roof crossbeam to play a fixing role, so that the vehicle expansion dock can be installed on the roof of the vehicle, which is convenient for users to use; at the same time, the decorative cover 11 can play a decorative and protective role, ensuring the beauty of the vehicle interior and improving the comfort of users when using the vehicle expansion dock 1 and mobile devices in the car.
