Description

Technical Field

[0001] This application relates to the field of automotive parts, specifically a snap-in docking station. Background Technology

[0002] With the proliferation of in-vehicle electronic devices (such as smartphones, tablets, navigation systems, and dashcams), the shortcomings of traditional in-vehicle interfaces (such as cigarette lighters or single USB ports) in terms of quantity, functionality, and compatibility have become increasingly apparent. Early solutions typically only provided basic charging functions, facing problems such as limited interfaces, low charging efficiency, lack of high-speed data transmission, and lack of support for multi-device collaboration. The new generation of automotive docking stations, by integrating modules for multi-protocol fast charging (such as USB PD and QC), high-speed data transmission (USB 3.1 / Thunderbolt), video output (HDMI), and wireless connectivity (CarPlay / Android Auto), combined with intelligent power management and heat dissipation design, solves the challenges of power supply, connectivity, and compatibility when multiple devices are used simultaneously. It also complies with automotive electromagnetic compatibility and safety standards, becoming a core component for connectivity and expansion in the smart cockpit ecosystem.

[0003] Currently, many car models have power interfaces on the inner wall of the armrest box, and the expansion dock has a connector on one side. The expansion dock is inserted into the power interface on the inner wall of the armrest box through this connector to achieve a detachable connection with the armrest box. However, current expansion docks generally suffer from inconvenient installation. On the one hand, the surface structure of the expansion dock is simple, and to fix it to the inner wall of the armrest box, an external structure is needed for fixation. Adding an external fixing structure makes installation and disassembly cumbersome and increases the complexity of using the expansion dock. Adhesive bonding is not conducive to the detachability of the expansion dock, and adhesive residue will also be left on the adhesive and the inner wall of the armrest box. On the other hand, in order to minimize the space occupied by the expansion dock inside the armrest box, it needs to be placed in the middle of the inner wall of the armrest box, so that the bottom of the expansion dock is suspended, allowing for better storage in the armrest box. However, this method leaves the bottom of the expansion dock without support, making the installation more difficult. Moreover, during use after installation, the expansion dock is usually subjected to pressure or tension when plugging and unplugging the charging plug, which can easily cause the expansion dock to move up and down, which is not conducive to the stability of the installation. Utility Model Content

[0004] To solve, or at least partially solve, the aforementioned technical problems, this application provides a snap-in expansion dock, including a housing, the housing having:

[0007] The third and fourth sidewalls are respectively adjacent to the opposite sides of the first and second sidewalls. The distance between the third and fourth sidewalls is adapted to the distance between the second and third inner walls on opposite sides of the armrest box, so that when the connector is inserted into the power interface, the third sidewall abuts against the second inner wall of the armrest box, and the fourth sidewall abuts against the third inner wall of the armrest box.

[0011] Optionally, the surfaces of the third sidewall and the fourth sidewall are respectively provided with a plurality of anti-slip protrusions, and the anti-slip protrusions are arranged at intervals along the direction away from the second sidewall.

[0012] Optionally, both the third and fourth sidewalls have flexible surfaces, and tensioning mechanisms are respectively provided on the inner sides of the third and fourth sidewalls, which are used to provide outward tension to the third and fourth sidewalls.

[0013] Optionally, a handle is provided on the second sidewall;

[0015] The handle includes a recess located on the surface of the second sidewall, the recess being able to accommodate a finger.

[0016] Optionally, a stepped structure is formed at the junction of the second sidewall and the first sidewall, and when the first sidewall is attached to the first inner wall, a second gap is formed between the stepped structure and the first inner wall to accommodate a fingernail.

[0017] Optionally, a magnetic attraction structure is provided on the surface or inner side of the first sidewall, the magnetic attraction structure being used to attract the magnetic element corresponding to the first inner wall when the first sidewall is close to the first inner wall.

[0018] Optionally, the connector is tilted toward the side away from the second sidewall.

[0019] The snap-in expansion dock provided in this application has a first sidewall of the housing that fits against the first inner wall of the armrest box. A connector is provided on the first sidewall for connecting to the power interface of the first inner wall. A second sidewall is adjacent to the first sidewall and has a charging interface. The charging interface is electrically connected to the connector via a circuit board disposed within the housing. A third and fourth sidewall are respectively adjacent to the opposite sides of the first and second sidewalls. The distance between the third and fourth sidewalls is adapted to the distance between the opposite sides of the second and third inner walls of the armrest box, so that when the connector is inserted into the power interface, the third and fourth sidewalls abut against the second and third inner walls of the armrest box, respectively. The expansion dock is snapped into the armrest box by abutting against the inner walls of the armrest box via the third and fourth sidewalls, realizing quick installation and removal of the expansion dock. The expansion dock can be snapped into the middle of the inner wall of the armrest box, achieving floating installation, which is convenient for wiring, beneficial for the utilization of the internal space of the armrest box, and can withstand a certain degree of force when plugging and unplugging the charging connector, resulting in high installation stability.

[0040] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides a snap-in expansion dock. The housing 10 of the expansion dock has a first side wall 11 on one side. A connector 111 is provided on the first side wall 11. The connector 111 is fixedly connected to the circuit board inside the housing 10 and extends out of the first side wall 11 for connecting to the power interface 211 on the first inner wall 21 of the armrest box.

[0043] The upper surface of the dock housing 10 has a second sidewall 12, which is adjacent to the first sidewall 11. A plurality of charging ports 121 are provided on the second sidewall 12. The charging ports 121 are electrically connected to the connector 111 through a circuit board provided in the housing 10. The charging ports 121 are used to connect the charging plug 30 to charge the electronic device.

[0044] The expansion dock housing 10 is also provided with a third side wall 13 and a fourth side wall 14 on both sides. The third side wall 13 and the fourth side wall 14 are respectively adjacent to the opposite sides of the first side wall 11 and the second side wall 12. That is, the first side wall 11 can be understood as the rear side of the housing 10, the second side wall 12 can be understood as the top surface of the housing 10, and the third side wall 13 and the fourth side wall 14 are the left and right sides of the housing 10, respectively.

[0045] In this embodiment, the distance between the third sidewall 13 and the fourth sidewall 14 can be considered as the width of the housing 10. The first inner wall 21 of the armrest box has a second inner wall 22 and a third inner wall 23 on opposite sides, and the distance between the second inner wall 22 and the third inner wall 23 can be considered as the width of the armrest box. The distance between the third sidewall 13 and the fourth sidewall 14 is adapted to the distance between the second inner wall 22 and the third inner wall 23 on opposite sides of the armrest box.

[0046] like Figure 3 As shown, when the connector 111 is inserted into the power interface 211, the first side wall 11 of the housing 10 fits against the first inner wall 21 of the armrest box, and the third side wall 13 of the housing 10 abuts against the second inner wall 22 of the armrest box, and the fourth side wall 14 of the housing 10 abuts against the third inner wall 23 of the armrest box. The housing 10 is then secured inside the armrest box. In this way, the expansion dock can be installed and fixed inside the armrest box without the aid of an external structure. Moreover, the installation and disassembly steps of the expansion dock are simple. It can be inserted or pulled out according to the extension direction of the connector 111, which also avoids the disadvantages of using adhesive bonding.

[0047] In this embodiment, the expansion dock is secured within the armrest box by abutting against the inner walls on both sides via the third side wall 13 and the fourth side wall 14, enabling quick installation and removal of the expansion dock. The expansion dock can be positioned in the middle of the inner wall of the armrest box, allowing for a floating installation state, facilitating wiring. The bottom of the expansion dock is hollowed out, which benefits the utilization of the internal space of the armrest box. Furthermore, the width of the housing 10 is adapted to the width of the armrest box. When the bottom of the expansion dock lacks support, the force on the housing 10 is transferred to the second inner wall 22 and the third inner wall 23 of the armrest box, thus withstanding a certain degree of force when plugging and unplugging the charging connector, preventing the expansion dock from shifting when the charging plug 30 is inserted during charging.

[0048] Preferably, in one embodiment, the distance between the third sidewall 13 and the fourth sidewall 14 gradually decreases in the direction away from the second sidewall 12, that is, the expansion dock has a trapezoidal shape that is wider at the top and narrower at the bottom. The inclined third sidewall 13 and fourth sidewall 14 can better cooperate with the second inner wall 22 and the third inner wall 23 of the armrest box, thereby improving the stability of the second inner wall 22 and the third inner wall 23 in supporting the expansion dock.

[0049] In some models, the second inner wall 22 and the third inner wall 23 of the armrest box are inclined, and the distance between the second inner wall 22 and the third inner wall 23 gradually decreases from top to bottom. The inclined third side wall 13 and the fourth side wall 14 can have a larger contact area with the second inner wall 22 and the third inner wall 23 of the armrest box, and the inclined second inner wall 22 and the third inner wall 23 can provide upward support for the docking station, improving support stability.

[0050] like Figure 4As shown, in one embodiment, the surfaces of the third sidewall 13 and the fourth sidewall 14 are respectively provided with buffer layers 40. The buffer layers 40 are elastic. When the housing 10 of the expansion dock is inserted into the armrest box, the buffer layers 40 can be squeezed and contracted when the third sidewall 13 abuts against the second inner wall 22, or the fourth sidewall 14 abuts against the third inner wall 23, so as to provide a preset pressure in the abutment state of the third sidewall 13 and the fourth sidewall 14, thereby improving the stability of the housing 10 of the expansion dock and the armrest box.

[0051] Specifically, the buffer layer 40 can be made of materials such as sponge or silicone. The buffer layer 40 can be set on the outer surface of the third side wall 13 and the fourth side wall 14, or the third side wall 13 and the fourth side wall 14 can be made of flexible material, and the buffer layer 40 can be set on the inner surface of the third side wall 13 and the fourth side wall 14. The third side wall 13 and the fourth side wall 14 can deform and have elasticity when squeezed.

[0052] Furthermore, in some embodiments, the surface of the first sidewall 11 is provided with an anti-slip layer 50. Since the first sidewall 11 has a large area that fits against the first inner wall 21 of the armrest box, the contact between the anti-slip layer 50 and the first inner wall 21 of the armrest box can increase the friction between the expansion dock and the armrest box and prevent the expansion dock from moving.

[0053] Similarly, the anti-slip layer 50 can extend to the surfaces of the third side wall 13 and the fourth side wall 14. When the connector 111 is inserted into the power interface 211, the anti-slip layer 50 is in contact with the first inner wall 21, the second inner wall 22 and the third inner wall 23 of the armrest box, respectively, to further increase friction and improve the stability of the expansion dock installation.

[0054] Preferably, the connection between the first sidewall 11 and the third sidewall 13 and the fourth sidewall 14 is rounded to match the inner corner of the armrest box. The anti-slip layer 50 can be made of materials such as silicone.

[0055] like Figure 4 As shown, in one embodiment, the third sidewall 13 and the fourth sidewall 14 of the expansion dock can be provided with a buffer layer 40 and an anti-slip layer 50 at the same time, taking into account both installation pressure and anti-slip performance.

[0056] In one embodiment, the anti-slip layers 50 surfaces of the third sidewall 13 and the fourth sidewall 14 are respectively provided with a plurality of anti-slip protrusions 51, which are spaced apart along a direction away from the second sidewall 12 to increase the resistance of the dock sliding down. Of course, the surface of the first sidewall 11 can also be provided with corresponding anti-slip protrusions 51.

[0057] Example 2

[0058] This embodiment provides a snap-in expansion dock. Based on the above embodiment, this embodiment further improves the structure of the expansion dock.

[0059] The expansion dock in this embodiment has the same structure as the one mentioned in the previous embodiment. The improvement is that the third side wall 13 and the fourth side wall 14 of the expansion dock are made into flexible side walls, and tensioning mechanisms are respectively provided on the inner side of the third side wall 13 and the fourth side wall 14. The tensioning mechanisms are used to provide outward tension to the third side wall 13 and the fourth side wall 14 to increase the pressure between the third side wall 13 and the fourth side wall 14 and the inner wall of the armrest box, thereby improving the installation stability of the expansion dock.

[0060] Specifically, such as Figure 5 As shown, the tensioning mechanism includes an elastic combination of a fixed seat 61 and a movable rib 63. The fixed seat 61 is provided inside the housing 10. The movable rib 63 is mounted on the fixed seat 61 by a number of first springs 62. The movable rib 63 has a certain curvature and abuts against the inner wall of the third side wall 13 or the fourth side wall 14 to provide outward tension to the third side wall 13 or the fourth side wall 14.

[0061] When the expansion dock is inserted into the inner wall of the armrest box, the third side wall 13 or the fourth side wall 14 contacts the inner wall of the armrest box and presses against the movable rib plate 63. The first spring 62 contracts to appropriately reduce the width of the expansion dock. The contraction of the first spring 62 provides pressure, causing the movable rib plate 63 to press against the third side wall 13 or the fourth side wall 14, ensuring the contact pressure between the third side wall 13 or the fourth side wall 14 and the inner wall of the armrest box, and improving the installation stability of the expansion dock.

[0062] When you need to disassemble the docking station, simply pull it out along the direction of connector 111. The operation is simple and convenient.

[0063] Example 3

[0064] This embodiment provides a snap-in expansion dock. Based on the above embodiment, this embodiment further improves the tensioning mechanism in the expansion dock.

[0065] like Figure 6 As shown, the tensioning mechanism of this embodiment includes a track 71 and an arched rib 74 mounted on the track 71. Two sliders 72 are provided on the track 71, and the sliders 72 are respectively connected to a second spring 73 arranged along the extension direction of the track 71. The two ends of the arched rib 74 are respectively connected to the sliders 72. The arched rib 74 is elastic. When the arched rib 74 is squeezed, the deformation of the arched rib 74 will be converted into the movement of the sliders 72.

[0066] In this embodiment, the arched rib 74 abuts against the third side wall 13 or the fourth side wall 14. When the expansion dock is inserted into the inner wall of the armrest box, the third side wall 13 or the fourth side wall 14 contacts the inner wall of the armrest box and squeezes the arched rib 74. The arched rib 74 deforms and squeezes the second spring 73. The second spring 73 contracts to provide pressure, so that the arched rib 74 presses against the third side wall 13 or the fourth side wall 14, ensuring the contact pressure between the third side wall 13 or the fourth side wall 14 and the inner wall of the armrest box, and improving the installation stability of the expansion dock.

[0067] The arched rib 74 is designed to fit the flexible third sidewall 13 or fourth sidewall 14, ensuring that the third sidewall 13 or fourth sidewall 14 can deform according to a certain arc to accommodate the width of the armrest box. When it is necessary to disassemble the expansion dock, simply pull it out along the direction of the connector 111; the operation is simple and convenient.

[0068] Example 4

[0069] This embodiment provides a snap-in expansion dock. Based on the above embodiment, this embodiment provides another form of tensioning mechanism.

[0070] like Figure 7 As shown, the tensioning mechanism in this embodiment includes a combination of a rotating rib plate 81 and a worm gear transmission assembly. Unlike the automatically adjustable tensioning mechanism in the above embodiments, the tensioning mechanism in this embodiment is manually adjustable.

[0071] The rotating rib 81 abuts against the third sidewall 13 or the fourth sidewall 14. The rotating rib 81 is arc-shaped to facilitate its cooperation with the flexible third sidewall 13 or the fourth sidewall 14. One end of the rotating rib 81 is rotatably connected to the housing 10 via a rotating shaft 82. The rotation of the rotating rib 81 around the rotating shaft 82 can push the third sidewall 13 or the fourth sidewall 14 to extend, thereby changing the width of the expansion dock.

[0072] The worm gear drive assembly includes a worm 84 and a worm 85 that mesh with each other. The worm 84 simultaneously meshes with two racks 83. The two racks 83 extend to the rotating ribs 81 inside the third side wall 13 and the fourth side wall 14, respectively. The two racks 83 are respectively arranged in the sliding grooves 831 inside the housing 10 to ensure that the racks 83 reciprocate in a predetermined direction.

[0073] Please see Figure 7 In this embodiment, the turbine 84 is a coaxial double gear, one of which meshes with two racks 83, and the other gear is the turbine body, which meshes with the worm 85 so that the worm 85 is offset from the two racks 83. The worm 85 is perpendicular to the two racks 83, and one end of the worm 85 extends to be connected to the adjustment device 86.

[0074] The adjusting device 86 can be a circular knob, which is coaxially connected to the worm gear 85. The adjusting device 86 is located outside the housing 10 and can be rotated by the vehicle owner.

[0075] By rotating the adjusting device 86, the adjusting device 86 drives the worm gear 85 to rotate, the worm gear 85 drives the turbine 84 to rotate, and the turbine 84 drives the two racks 83 to move in opposite directions. The two racks 83 respectively drive the corresponding rotating ribs 81 to rotate. When the rotating ribs 81 rotate outward, they push the third side wall 13 or the fourth side wall 14 to extend outward. When the expansion dock is inserted into the armrest box, the rotating ribs 81 provide outward tension to the third side wall 13 or the fourth side wall 14 to increase the pressure between the third side wall 13 or the fourth side wall 14 and the inner wall of the armrest box, thereby improving the stability of the expansion dock installation.

[0076] When the expansion dock needs to be disassembled, rotate the adjustment device 86 in the opposite direction, rotate the rib plate 81 inward, and retract the third side wall 13 or the fourth side wall 14 inward, reducing the width of the expansion dock, so that the expansion dock can be removed from the armrest box.

[0077] In this embodiment, the rotating rib 81 can also be replaced by the movable rib 63 in embodiment 2, which can achieve the same effect as described above.

[0078] Example 5

[0079] This embodiment provides a snap-in expansion dock. To facilitate the disassembly of the expansion dock, the second side wall 12 of the expansion dock has been improved in this embodiment.

[0080] In this embodiment, a handle is provided on the second sidewall 12. The handle can be a protrusion located on the surface of the second sidewall 12. The protrusion is used to contact the driver's fingers, so that the fingers can grasp the second sidewall 12 and disassemble the docking station in a horizontal direction. When the first sidewall 11 is attached to the first inner wall 21, a first gap is formed between the protrusion and the first inner wall 21, which can accommodate the fingers. The driver's fingers can be inserted into the first gap to facilitate disassembling the docking station in an almost horizontal direction.

[0081] In one embodiment, the handle may be a recess located on the surface of the second sidewall 12, the recess having a certain width, allowing the vehicle owner's fingers to be inserted into the recess to facilitate the horizontal disassembly of the docking station.

[0082] In one embodiment, such as Figure 3As shown, a stepped structure is formed at the intersection of the second sidewall 12 and the first sidewall 11. When the first sidewall 11 is attached to the first inner wall 21, a second gap is formed between the stepped structure and the first inner wall 21. In order not to affect the flatness of the docking station surface, in this embodiment, the size of the second gap is small, and its width is just enough to accommodate a fingernail. When disassembling the docking station, the car owner extends his fingernail into the second gap and uses the fingernail in conjunction with his finger to pry the docking station outward.

[0083] Furthermore, in some embodiments, a magnetic attraction structure, such as a magnetic patch or a magnet, is provided on the surface or inner side of the first sidewall 11, and a magnetic attracting element corresponding to the magnetic attraction structure is provided on the surface of the first inner wall 21. When one is a magnetic patch or a magnet, the other can also be a metal part, as long as they can attract each other. Simultaneously, the positions of the magnetic attraction structure and the magnetic attracting element are set so that when the connector 111 is inserted into the power interface 211, the magnetic attraction structure and the magnetic attracting element can attract each other accordingly. When installing the docking station, the connector 111 is brought close to the power interface 211, and through the attraction between the magnetic attraction structure and the magnetic attracting element, the connector 111 can be easily inserted into the power interface 211, achieving quick alignment and installation of the docking station. This avoids situations where the connector 111 and the power interface 211 are difficult to align, and the first sidewall 11 adheres to the first inner wall 21 through the attraction between the magnetic attraction structure and the magnetic attracting element, improving the stability of the docking station installation. The magnetic attraction structure can be correspondingly disposed within the connector 111 and the power interface 211.

[0084] Example 6

[0085] This embodiment provides a snap-in expansion dock. Based on the above embodiment, this embodiment improves the installation method of connector 111.

[0086] In the above embodiments, the connector 111 is generally perpendicular to the first side wall 11, and the power interface 211 is also perpendicular to the first inner wall 21 of the armrest box.

[0087] In some models, in order to make the power interface 211 easier to observe, the power interface 211 is tilted relative to the inner wall of the first inner wall 21 of the armrest box, with the power interface 211 facing diagonally upwards for easy observation.

[0088] Therefore, in this embodiment, connector 111 is not perpendicular to the first sidewall 11; connector 111 is tilted towards the side away from the second sidewall 12. When installing the expansion dock, the expansion dock is inserted at an angle relative to the first inner wall 21 of the armrest box. Connector 111 forms a hook with the first sidewall 11, hanging the expansion dock on the first inner wall 21 of the armrest box. At this time, connector 111 can be provided with corresponding reinforcing ribs to appropriately bear the installation pressure of the expansion dock, preventing the expansion dock from moving and allowing it to be stably locked in the middle position of the inner wall of the armrest box, thereby reducing the space occupied at the bottom of the armrest box.

[0089] Similarly, the tilted design of connector 111 allows the docking station to withstand greater downward pressure, preventing the docking station from moving or falling off due to the pressure of the charging plug 30 on it during charging.
