The various technical effects of the preferred technical solution among the many technical solutions provided by this utility model are described in detail below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The charging terminal storage and fixing structure provided by this utility model includes a housing, a button, and a clamping arm assembly located within the housing, wherein:

[0007] The housing is provided with an insertion port, the clamping arm assembly is located inside the housing, and the two ends of the clamping arm assembly are respectively formed with a clamping part and a force-applying part;

[0008] The button is slidably connected to the housing and located on the movement path of the button. When the button is not under force, the clamping part is in a closed state and forms a clamping cavity communicating with the socket, thereby clamping and fixing the charging terminal.

[0009] When the button is pressed by an external force, it can pinch the force-applying part, thereby opening the clamping part and releasing the charging terminal.

[0010] Preferably, the clamping arm assembly includes a first clamping arm, a second clamping arm, a shaft, and a torsion spring, wherein:

[0011] The first clamping arm and the second clamping arm are hinged together by the shaft, which is fixed inside the housing; the torsion spring is sleeved outside the shaft, and the two free ends of the torsion spring abut against the first clamping arm and the second clamping arm, respectively;

[0012] When the torsion spring is in its initial state, the ends of the first clamping arm and the second clamping arm facing the insertion port close to form the clamping part, and the other ends of the first clamping arm and the second clamping arm form the force-applying part.

[0013] Preferably, the inner sides of the first clamping arm and the second clamping arm are provided with buckles, and when the clamping part is in the closed state, the buckles and the inner walls of the first clamping arm and the second clamping arm form a clamping cavity.

The first guide slope and the second guide slope are mirror images of each other about the axis of symmetry of the button, and the straight distance between the first guide slope and the second guide slope gradually decreases in the direction away from the clamping part.

[0017] When the button is pressed in the direction toward the inside of the housing, the first guide slope and the second guide slope press against the force-applying part, thereby opening the clamping part.

[0018] Preferably, the clamping part has mating inclined surfaces on opposite sides, and the mating inclined surfaces are arranged parallel to the corresponding first guide inclined surface or second guide inclined surface.

[0022] One end of the elastic element is fixed inside the housing, and the other end of the elastic element abuts against the push plate body;

[0023] The push plate body is slidably connected to the housing. When the charging terminal is clamped in the clamping arm assembly, the push plate body abuts against the charging terminal, and the elastic element is in a compressed state.

[0024] When the clamping part is in the open state, the elastic member pushes the push plate body to move toward the charging end, thereby causing the charging end to pop out of the clamping part.

[0025] This utility model also provides a power bank, including a charging cable, a charging terminal, and a charging terminal storage and fixing structure. One end of the charging cable is fixed inside the housing, and the charging terminal is disposed at the other end of the charging cable.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] This utility model provides a charging terminal storage and fixing structure and a power bank that can store and remove the charging terminal without using a large external force, making it convenient to use, preventing the charging cable tail from breaking, and improving the service life of the charging cable.

[0045] The following is combined with Figures 2-12 The technical solution provided by this utility model will be described in more detail.

[0046] Example 1:

[0047] The charging terminal storage and fixing structure provided by this utility model includes a housing 1, a button 2, and a clamping arm assembly 3 located inside the housing 1. The housing 1 is provided with an insertion port 5. The clamping arm assembly 3 is located inside the housing 1, and the two ends of the clamping arm assembly 3 are respectively formed with a clamping part 31 and a force-applying part 32. The button 2 is slidably connected to the housing 1 and is located on the movement path of the button 2. When the button 2 is not under force, the clamping part 31 is in a closed state and forms a clamping cavity 39 communicating with the insertion port 5, thereby clamping and fixing the charging terminal 200. When the button 2 is pressed by external force, it can pinch the force-applying part 32, thereby opening the clamping part 31 and releasing the charging terminal 200.

[0048] One end of the charging cable 100 is electrically connected to the internal circuitry of the power bank and is fixed inside the power bank. The connection structure between the charging cable 100 and the power bank is a mature technology and will not be described in detail here. The other end of the charging cable 100 is provided with the aforementioned charging connector 200. The charging connector 200 can be a Type-C interface or other interfaces, which are not limited here.

[0049] In this embodiment, the charging terminal storage and fixing structure allows the charging terminal 200 of the charging cable 100 included with the power bank to be inserted through the socket 5 of the housing 1. The charging terminal 200 is clamped and fixed in the clamping part 31 of the clamping arm assembly 3. When it is necessary to remove the charging terminal 200, the button 2 on the housing 1 is pressed. The button 2 pinches the force application part 32 of the clamping arm assembly 3, causing the clamping part 31 of the clamping arm assembly 3 to open, allowing the charging terminal 200 to be removed directly without requiring significant external force. Compared to the prior art fixing structure where the groove on the housing 1 and the charging terminal 200 are interference-fitted, this charging terminal storage and fixing structure can achieve the storage and removal of the charging terminal 200 without the need for significant external force, making it convenient to use, preventing the end of the charging cable 100 from breaking, and improving the service life of the charging cable 100.

[0050] As an optional implementation, see Figure 5 and Figure 7 As shown, the clamping arm assembly 3 of this embodiment includes a first clamping arm 33, a second clamping arm 34, a shaft portion 35, and a torsion spring 36, wherein: the first clamping arm 33 and the second clamping arm 34 are hinged together by the shaft portion 35, and the shaft portion 35 is fixed inside the housing 1; the torsion spring 36 is sleeved outside the shaft portion 35, and the two free ends of the torsion spring 36 abut against the first clamping arm 33 and the second clamping arm 34 respectively; when the torsion spring 36 is in the initial state, the ends of the first clamping arm 33 and the second clamping arm 34 facing the insertion port 5 are closed and form a clamping portion 31, and the other ends of the first clamping arm 33 and the second clamping arm 34 form a force-applying portion 32.

[0051] The first clamping arm 33 and the second clamping arm 34 can both be moving clamping arms, or one can be a moving clamping arm and the other a fixed clamping arm.

[0052] See Figure 5 and Figure 7 As shown, the first clamping arm 33 and the second clamping arm 34 are hinged together by a shaft 35, forming a clamping part 31 and a force-applying part 32 at each end. When an external force is applied to the force-applying part 32, the clamping part 31 opens. (See Figure 34) Figure 8 As shown, the charging end 200 can be removed without external force to pry out the charging connector.

[0053] As an optional implementation, see Figure 5 , Figure 9 and Figure 10 As shown, the inner sides of the first clamping arm 33 and the second clamping arm 34 are provided with buckles 37. When the clamping part 31 is in the closed state, the buckles 37 and the inner walls of the first clamping arm 33 and the second clamping arm 34 form a clamping cavity 39. The charging end 200 is provided with a protrusion 201. The insertion side of the buckle 37 is provided with a guide slope 331. The insertion side of the protrusion 201 is provided with an arc guide 202. The arc guide 202 and the guide slope 331 cooperate to push the clamping part 31 to open, so that the protrusion 201 is clamped and fixed in the clamping cavity 39.

[0054] When the user puts away the charging connector 200, the charging connector 200 is inserted into the socket 5. Because the protrusion 201 is provided with an arc-shaped guide part 202, see [reference needed]. Figure 9 and Figure 10 As shown, the arc-shaped guide portion 202 can first extend into the clamping portion 31 along the guide slope 331 of the buckle 37. The clamping portion 31 formed by the first clamping arm 33 and the second clamping arm 34 opens under force, and the charging end 200 smoothly enters the clamping cavity 39 of the clamping portion 31. The clamping portion 31 then closes. (See Figure 1) Figure 3 and Figure 4 As shown, the charging end 200 is clamped and fixed.

[0055] The cooperative structure of the guide slope 331 of the buckle 37 and the arc guide portion 202 facilitates the insertion and fixation of the charging end 200 into the clamping portion 31.

[0056] As an optional implementation, see Figure 4 and Figure 5 , Figure 6 As shown, Figure 6 The arrow in the middle indicates the pressing direction. The button 2 includes a button body 21, a first leg 22 and a second leg 23 fixed on the button body 21. The force application part 32 is located between the first leg 22 and the second leg 23. When the button 2 is pressed in the direction toward the inside of the housing 1, the first leg 22 and the second leg 23 squeeze the force application part 32, thereby opening the clamping part 31.

[0057] For details, see Figure 4 and Figure 5 , Figure 6 As shown, the first leg 22 and the second leg 23 are respectively provided with a first guide slope 24 and a second guide slope 25 on opposite sides. The first guide slope 24 and the second guide slope 25 are mirror images of each other about the axis of symmetry of the button 2, and the straight distance between the first guide slope 24 and the second guide slope 25 gradually decreases in the direction away from the clamping part 31. When the button 2 is pressed in the direction towards the inside of the housing 1, the first guide slope 24 and the second guide slope 25 squeeze the force application part 32, thereby opening the clamping part 31.

[0058] See Figure 6 As shown, when button 2 is pressed in the direction of the arrow, the first guide slope 24 and the second guide slope 25 pinch the force application part 32 of the first clamping arm 33 and the second clamping arm 34, and the force application part 32 tightens, thereby opening the clamping part 31. See [link / reference] Figure 8 As shown, this configuration allows the clamping part 31 to open when button 2 is pressed. When the external force acting on the button body 21 is removed, the first clamping arm 33 and the second clamping arm 34 return to their original positions under the action of the torsion spring 36, and the force-applying part 32 expands outward. Similarly, by pushing the first guide slope 24 and the second guide slope 25, button 2 is reset.

[0059] As an optional implementation, see Figure 6 As shown, the clamping part 31 has a mating inclined surface 38 on both sides. The mating inclined surface 38 is arranged parallel to the corresponding first guide inclined surface 24 or second guide inclined surface 25. When the button 2 pinches the force application part 32, the mating inclined surface 38 slides relative to the corresponding first guide inclined surface 24 or second guide inclined surface 25.

[0060] The inclined surface 38 works in conjunction with the first guide inclined surface 24 and the second guide inclined surface 25 to enable the pressing button 2 to drive the clamping part 31 to open.

[0061] As an optional implementation, see Figure 6 As shown, both the first leg 22 and the second leg 23 include a limiting part 26. The limiting part 26 is disposed on the side of the first guide slope 24 or the second guide slope 25 facing the clamping arm assembly 3, and the force-applying part 32 is located between the two limiting parts 26.

[0062] When button 2 is not pressed, the force-applying part 32 of the clamping arm assembly 3 is located between the two limiting parts 26, which can always maintain the cooperation between button 2 and force-applying part 32 and prevent the force-applying end from disengaging from button 2.

[0063] As an optional implementation, see Figure 3 and Figure 4As shown, the charging terminal storage and fixing structure of this embodiment also includes a push plate assembly located inside the housing 1. When the charging terminal 200 is clamped in the clamping arm assembly 3, the push plate assembly abuts against the charging terminal 200. When the clamping part 31 is in the open state, the push plate assembly pushes the charging terminal 200 out of the clamping arm assembly 3.

[0064] When button 2 is pressed and clamping part 31 opens, push plate assembly can eject charging end 200 from clamping part 31, which can prevent the clamping part 31 from closing when the external force acting on button 2 is removed before the user can pull out charging end 200.

[0065] As an optional implementation, see Figure 3 and Figure 4 , Figure 11 and Figure 12 As shown, the push plate assembly of this embodiment includes a push plate body 41 and an elastic member 42, wherein: one end of the elastic member 42 is fixed inside the housing 1, and the other end of the elastic member 42 abuts against the push plate body 41; the push plate body 41 is slidably connected inside the housing 1; when the charging terminal 200 is clamped in the clamping arm assembly 3, the push plate body 41 abuts against the charging terminal 200, and the elastic member 42 is in a compressed state; when the clamping part 31 is in an open state, the elastic member 42 pushes the push plate body 41 to move toward the charging terminal 200, thereby causing the charging terminal 200 to pop out of the clamping part 31. The elastic member 42 can be a return spring.

[0066] See Figure 3 and Figure 4 , Figure 11 As shown, when the charging terminal 200 is not removed for use, it is clamped and fixed in the clamping part 31 of the clamping arm assembly 3. The buckle 37 of the clamping arm assembly 3 cooperates with the protrusion 201 on the charging terminal 200 to lock the charging terminal 200.

[0067] When the user wants to remove the charging connector 200, see [link / reference]. Figure 6 , Figure 9 and Figure 10 As shown, pressing button 2 on the end face of the product housing 1 causes button 2 to grip the force application part 32 of the clamping arm assembly 3 via the first guide slope 24 and the second guide slope 25. The clamping part 31 of the clamping arm assembly 3 opens, preventing it from further gripping the charging terminal 200. (See attached image) Figure 12 When the locking effect of the clamping arm assembly 3 on the charging terminal 200 disappears, the push plate body 41 pushes out the charging terminal 200 under the elastic action of the elastic member 42. After releasing the button 2, the clamping arm assembly 3 resets and the clamping part 31 closes.

[0068] When the user puts away the charging connector 200, the charging connector 200 is inserted into the socket 5. Because the protrusion 201 is provided with an arc-shaped guide part 202, see [reference needed]. Figure 9and Figure 10 As shown, the arc-shaped guide portion 202 can first extend into the clamping portion along the guide slope 331 of the buckle 37. The clamping portion 31 formed by the first clamping arm 33 and the second clamping arm 34 opens under force, and the charging end 200 smoothly enters the clamping cavity 39 of the clamping portion. The clamping portion 31 then closes. (See Figure 1) Figure 3 and Figure 4 As shown, the charging end 200 is clamped and fixed.
