[0033] An embodiment of the present application provides a support type expansion dock. Figure 1 、 Figure 2 and Figure 3 The support-type expansion dock includes a shell assembly 10 and a data cable 20.

[0034] The housing assembly 10 has a receiving groove 10 a extending along a first direction. Along the first direction, opposite ends of the receiving groove 10 a are open to form wire outlets 10 b , respectively.

[0035] One end of the data cable 20 is disposed in the housing assembly 10, and at least a portion of the data cable 20 is movably disposed in the accommodating groove 10a. The data cable 20 can be moved so that the other end of the data cable 20 can selectively extend out of the housing assembly 10 through one of the two outlets 10b.

[0036] Specifically, a support-type expansion dock refers to a device used to expand the interface functions of an electronic device.

[0037] The type of electronic device is not limited. For example, the electronic device is a laptop computer.

[0038] The support type expansion dock is used to expand the notebook computer interface on one hand, so as to expand more functions. On the other hand, the notebook computer can be placed on the support type expansion dock, which can provide support for the notebook computer.

[0039] The housing assembly 10 refers to a component that protects the internal components of the support-type expansion dock and forms the external shape of the support-type expansion dock.

[0040] The material type of the housing assembly 10 is not limited. For example, the housing assembly 10 is made of plastic. For another example, the housing assembly 10 is made of metal.

[0041] The data cable 20 is a component for connecting the supporting expansion dock and an external electronic device.

[0042] One end of the data cable 20 is located in the housing assembly 10 , and the other end can be extended through the cable outlet 10 b to be connected to an external electronic device.

[0043] The surface material of the data line 20 is not limited.

[0044] For example, the surface material of the data line 20 is TPU (thermoplastic polyurethane elastomer), thereby enabling the data line 20 to have good flexibility and wear resistance.

[0045] The receiving groove 10 a refers to a groove-shaped structure in the housing assembly 10 , which serves to position and guide the data cable 20 .

[0046] The wire outlet 10 b refers to an opening 10 c formed by opening both ends of the accommodating groove 10 a , and the data cable 20 can extend out of the housing assembly 10 through the wire outlet 10 b .

[0047] One end of the data cable 20 is disposed in the housing assembly 10 , and is actually used to connect to a circuit board in the support-type expansion dock.

[0048] According to actual conditions, the data line 20 may be partially movably disposed in the receiving groove 10 a , or the entire area may be movably disposed in the receiving groove 10 a .

[0049] The data cable 20 can be moved in any manner within the receiving groove 10 a , such as sliding, pulling, moving, or disassembling.

[0050] The data line 20 can be pulled out of the shell assembly 10 through the data line 20 activity, so as to be connected with the electronic device. The support docking station comprises the shell assembly 10 and the data line 20. The shell assembly 10 has a receiving groove 10a extending along a first direction, and the receiving groove 10a is open at opposite ends along the first direction to form two data line outlets 10b. One end of the data line 20 is arranged in the shell assembly 10, and at least a part of the data line 20 is movably arranged in the receiving groove 10a. The data line 20 can be moved so that the other end of the data line 20 can be selectively extended out of the shell assembly 10 through one of the two data line outlets 10b. Thus, the user can selectively extend the data line 20 out of the shell assembly 10 through different data line outlets 10b according to the port setting position of the electronic device, thereby improving the convenience of using the support docking station.

[0051] In one embodiment, referring to Figure 3 , the support docking station further comprises a circuit board connected with the data line 20, and the shell assembly 10 comprises a support panel 11 and a receiving cavity for mounting the circuit board. The support panel 11 is arranged on one side of the receiving cavity close to the top of the support docking station, and a part of the support panel 11 is recessed to form the receiving groove 10a. Thus, the internal space of the shell assembly 10 is fully utilized, and the structure of the support docking station is more compact.

[0052] Specifically, the support panel 11 is arranged on the top side of the shell assembly 10 and has a supporting effect.

[0053] The support panel 11 is not limited in the forming manner.

[0054] For example, the support panel 11 is integrally formed with the shell assembly 10.

[0055] For another example, the support panel 11 is detachably arranged on the shell assembly 10.

[0056] The circuit board is integrated with electronic components and circuits, and the circuit board is electrically connected with the data line 20 to realize data and power transmission and processing.

[0057] In one embodiment, referring to Figure 3 and Figure 4 , a part of the groove wall of the receiving groove 10a is open to form an opening 10c communicating with the receiving cavity. The opening 10c is located between the two data line outlets 10b, and one end of the data line 20 extends into the receiving cavity through the opening 10c to be connected with the circuit board. Thus, by arranging the opening 10c between the two data line outlets 10b, the extension length of the data line 20 extending out of the shell assembly 10 through the data line outlet 10b is reduced to a certain extent.

[0058] Specifically, the specific position of the opening 10c is not limited. For example, the opening 10c is located at the midpoint of the line connecting the two outlets 10b.

[0059] One end of the data cable 20 enters the accommodating cavity through the opening 10c to be electrically connected to the circuit board, and the other end extends out of the housing assembly 10 through the outlet 10b to be electrically connected to the electronic device.

[0060] The shape and size of the opening 10 c are not limited as long as the data line 20 can pass through.

[0061] In one embodiment, please refer to Figure 3 and Figure 4 The housing assembly 10 includes a first clamping portion 12, which is disposed at one end of the receiving groove 10a. The data cable 20 is clamped to the first clamping portion 12. Thus, by clamping the data cable 20 to the first clamping portion 12, the data cable 20 can be effectively fixed, thereby ensuring the stability of the position of the data cable 20.

[0062] Specifically, the structure type of the first engaging portion 12 is not limited, as long as it can be engaged with the data cable 20 .

[0063] Exemplarily, the first clamping portion 12 is a U-shaped component disposed in the accommodating groove 10 a , and the data cable 20 is clamped in the U-shaped space of the first clamping portion 12 .

[0064] Exemplarily, the first clamping portion 12 is an L-shaped component disposed in the receiving groove 10 a , one side of the first clamping portion 12 and one side of the receiving groove 10 a form a clamping space, and the data line 20 is clamped in the clamping space.

[0065] In one embodiment, please refer to Figure 4 Part of the first engaging portion 12 is recessed to form a first engaging slot 12a. At the opening of the first engaging slot 12a, a portion of the first engaging slot 12a's wall protrudes into the first engaging slot 12a to form a limiting protrusion 13. This ensures that the opening 10c of the first engaging slot 12a is smaller than the diameter of the data cable 20, thereby preventing the data cable 20 from escaping the first engaging slot 12a. This effectively prevents the data cable 20 from accidentally escaping the first engaging slot 12a, allowing it to remain stably within the first engaging slot 12a. This ensures the normal operation of the support-type expansion dock and reduces issues such as data transmission interruption or unstable power supply caused by a loose data cable 20.

[0066] Specifically, the shape of the first slot 12 a is not limited as long as it can fix the data cable 20 .

[0067] It can be understood that the inner diameter width of the first card slot 12a is greater than or equal to the diameter of the data cable 20, so that the data cable 20 can be set in the first card slot 12a, and a partial area at the notch of the first card slot 12a protrudes into the card slot to form a limiting protrusion 13. When the data cable 20 is located in the first card slot 12a, the limiting protrusion 13 can clamp the data cable 20 to prevent the data cable 20 from escaping from the first card slot 12a.

[0068] It is understood that the first engaging portion 12 is elastically deformable. Under the action of an external force, the first engaging portion 12 elastically deforms, allowing the data cable 20 to be positioned within the first engaging slot 12a. When the data cable 20 is within the first engaging slot 12a, the first engaging portion 12 returns to its original shape, allowing the limiting protrusion 13 to prevent the data cable 20 from exiting the first engaging slot 12a.

[0069] The number of the first card slots 12a is not limited. For example, the number of the first card slots 12a is one or more.

[0070] The shape of the limiting protrusion 13 is not limited.

[0071] For example, the protruding portion of the limiting protrusion 13 gradually narrows toward the interior of the card slot, thereby making it easier for the data cable 20 to be inserted into the card slot. Specifically, during the insertion process, the data cable 20 gradually expands the notch of the first card slot 12a along the inclined surface of the limiting protrusion 13. When the data cable 20 is fully inserted, the limiting protrusion 13 can effectively prevent the data cable 20 from being removed from the first card slot 12a.

[0072] The material type of the limiting protrusion 13 is not limited.

[0073] For example, the limiting protrusion 13 is made of plastic or rubber with good elasticity. When the data cable 20 is inserted into or removed from the slot, the limiting protrusion 13 can be deformed to a certain extent, thereby reducing damage to the outer surface of the data cable 20.

[0074] The number of the limiting protrusions 13 is not limited.

[0075] For example, a portion of the groove wall on one side of the first slot 12a may protrude into the first slot 12a to form the limiting protrusion 13. Alternatively, a portion of the groove wall on both sides of the first slot 12a may protrude into the first slot 12a to form the limiting protrusion 13.

[0076] In one embodiment, please refer to Figure 4 The housing assembly 10 includes a second engaging portion 14, which is disposed at an end of the receiving groove 10a away from the first engaging portion 12. The data cable 20 engages with the second engaging portion 14. Thus, by engaging the data cable 20 with the second engaging portion 14, the data cable 20 can be effectively fixed, thereby ensuring the stability of the position of the data cable 20.

[0077] Specifically, the structure type of the second clamping portion 14 is not limited as long as it can be clamped with the data line 20.

[0078] Illustratively, the second clamping portion 14 is a U-shaped member arranged in the accommodating groove 10a, and the data line 20 is clamped in the U-shaped space of the second clamping portion 14.

[0079] Illustratively, the second clamping portion 14 is an L-shaped member arranged in the accommodating groove 10a, one side of the second clamping portion 14 forms a clamping space with one side of the accommodating groove 10a, and the data line 20 is clamped in the clamping space.

[0080] In an embodiment, referring to Figure 4 , a part of the second clamping portion 14 is recessed to form a second clamping groove 14a, at the slot opening of the second clamping groove 14a, a part of the groove wall of the second clamping groove 14a protrudes into the second clamping groove 14a to form a limiting protrusion 13, and the size of the opening 10c of the slot opening of the second clamping groove 14a is smaller than the diameter of the data line 20, so as to limit the data line 20 from being separated from the second clamping groove 14a. Thus, the accidental separation of the data line 20 from the second clamping groove 14a can be effectively prevented, so that the data line 20 can be stably positioned in the second clamping groove 14a, and the normal work of the support-type docking station is ensured, and problems such as data transmission interruption or unstable power supply caused by loose data line 20 are reduced.

[0081] Specifically, the shape of the second clamping groove 14a is not limited as long as it can fix the data line 20.

[0082] It can be understood that the inner diameter width of the second clamping groove 14a is greater than or equal to the diameter of the data line 20, so that the data line 20 can be arranged in the second clamping groove 14a, and a part of the slot opening of the second clamping groove 14a protrudes into the clamping groove to form a limiting protrusion 13, when the data line 20 is positioned in the second clamping groove 14a, the limiting protrusion 13 can clamp the data line 20 to prevent the data line 20 from being separated from the first clamping groove 12a.

[0083] It can be understood that the second clamping portion 14 can be elastically deformed, and under the action of external force, the second clamping portion 14 deforms elastically, so that the data line 20 can be arranged in the second clamping groove 14a. When the data line 20 is positioned in the second clamping groove 14a, the second clamping portion 14 restores to its original shape, so that the limiting protrusion 13 can limit the data line 20 from being separated from the second clamping groove 14a.

[0084] The number of the second clamping groove 14a is not limited. For example, the number of the second clamping groove 14a is one or more.

[0085] The shape of the limiting protrusion 13 is not limited.

[0086] For example, the protruding portion of the limiting protrusion 13 gradually narrows toward the interior of the card slot, thereby making it easier for the data cable 20 to be inserted into the card slot. Specifically, during insertion, the data cable 20 gradually opens the notch of the second card slot 14a along the inclined surface of the limiting protrusion 13. When the data cable 20 is fully inserted, the limiting protrusion 13 can effectively prevent the data cable 20 from falling out of the second card slot 14a.

[0087] The material type of the limiting protrusion 13 is not limited.

[0088] For example, the limiting protrusion 13 is made of plastic or rubber with good elasticity. When the data cable 20 is inserted into or removed from the slot, the limiting protrusion 13 can be deformed to a certain extent, thereby reducing damage to the outer surface of the data cable 20.

[0089] The number of the limiting protrusions 13 is not limited.

[0090] For example, a portion of the groove wall on one side of the second slot 14a may protrude into the first slot 12a to form the limiting protrusion 13. Alternatively, a portion of the groove wall on both sides of the second slot 14a may protrude into the first slot 12a to form the limiting protrusion 13.

[0091] In one embodiment, please refer to Figure 3 and Figure 4 The housing assembly 10 includes a deflection member 15, which is disposed on a side of the second engaging portion 14 facing away from the first engaging portion 12. The data cable 20 deflects around the deflection member 15 to change the extending direction of the data cable 20. Thus, by providing the deflection member 15, the supporting expansion dock can flexibly change the extending direction of the data cable 20 according to actual usage.

[0092] Specifically, the steering member 15 is a component used to change the extending direction of the data line 20.

[0093] The structural type of the deflection member 15 is not limited.

[0094] For example, the side of the steering member 15 facing away from the second clamping portion 14 is arc-shaped. Therefore, when the data cable 20 is turned through the steering member 15, the arc-shaped side of the steering member 15 can better fit the curved path of the data cable 20, preventing the surface of the data cable 20 from being scratched during the turning.

[0095] In one embodiment, a portion of the deflection member 15 on a side away from the second clamping portion 14 extends away from the second clamping portion 14 to form a mounting groove, and the data cable 20 is disposed in the mounting groove, thereby making the data cable 20 more stable.

[0096] In one embodiment, please refer to Figure 3 and Figure 4The second clamping portion 14 has two second clamping slots 14a spaced apart along a second direction, the second direction being perpendicular to the first direction, and the data cable 20 has a storage state and a use state;

[0097] When the data cable 20 is in the retracted state, the data cable 20 is engaged with one of the two second slots 14 a and then turns to engage with the other of the two second slots 14 a and the first engaging portion 12 in sequence.

[0098] When the data cable 20 is in use, the data cable 20 can be selectively engaged with one of the second engaging slots 14 a or the first engaging portion 12 .

[0099] Thus, the data line 20 can be further effectively fixed, thereby ensuring the position stability of the data line 20 .

[0100] Specifically, the first engaging portion 12 and the second engaging portion 14 are respectively disposed on opposite sides of the accommodating slot 10a. When the data cable 20 is in use and extends out of the housing assembly 10 from the cable outlet 10b adjacent to the first engaging portion 12, the data cable 20 engages with the first engaging portion 12. When the data cable 20 extends out of the housing assembly 10 from the cable outlet 10b adjacent to the second engaging portion 14, the data cable 20 engages with one of the second engaging slots 14a.

[0101] When the data cable 20 is in the storage state, the data cable 20 is engaged with the second card slot 14a along the second direction, close to the opening 10c, and is turned by the turning member 15 to engage with the other second card slot 14a and the first card portion 12, thereby enabling the data cable 20 to be firmly located in the accommodating slot 10a.

[0102] In one embodiment, please refer to Figure 4 and Figure 5 , the protruding length of the limiting protrusion 13 is greater than 0 mm and less than or equal to 0.2 mm. For example, the protruding length of the limiting protrusion 13 is 0.1 mm or 0.2 mm. Thus, maintaining the protruding length of the limiting protrusion 13 within the above range, on the one hand, facilitates the smooth entry of the data cable 20 into the first card slot 12 a or the second card slot 14 a. On the other hand, when the data cable 20 is located in the first card slot 12 a or the second card slot 14 a, the limiting protrusion 13 can effectively prevent the data cable 20 from escaping.
