DETAILED DESCRIPTION

[0056] In order to make the content of the utility model more easily be clearly understood, the following according to specific embodiment and combining with the drawings, the utility model is further detailed.

[0057] Embodiment 1:

[0058] Please refer to Figures 1 to 12 As shown in the figure, the embodiment provides a self-ejecting battery assembly, which comprises a containing cavity 11, a limiting buckle group arranged in the containing cavity 11, an elastic support piece 5 and a pushing piece, and a battery mounting rack 2 detachably matched with the containing cavity 11.

[0059] One side end of the containing cavity 11 is formed with an opening 19 suitable for the battery mounting rack 2 to enter and exit the containing cavity 11. The battery mounting rack 2 has a limiting bin 21 for accommodating the battery 3, and the battery 3 is reliably mounted into the containing cavity 11 by the assembly in place between the battery mounting rack 2 and the containing cavity 11, and when the battery mounting rack 2 is disassembled from the containing cavity 11, the battery 3 also leaves the containing cavity 11. The limiting buckle group comprises a buckle 41 suitable for being buckled with the battery mounting rack 2, and an elastic piece 42 connected with the buckle 41; the elastic support piece 5 is suitable for abutting against the battery mounting rack 2.

[0060] Based on the above structure, generally speaking, in the case that the battery mounting rack 2 and the accommodating cavity 11 are assembled in place, the buckle 41 is buckled with the battery mounting rack 2 in place, and the elastic support 5 is in a compressed deformed state, so that the elastic support 5 has elastic potential energy; and after the buckling state of the buckle 41 and the battery mounting rack 2 is released, the battery mounting rack 2 can be ejected from the accommodating cavity 11 under the deformation reset action of the elastic support 5, so that it is not necessary to manually disassemble the battery mounting rack 2 from the accommodating cavity 11.

[0061] For the release process of the buckling state of the buckle 41 and the battery mounting rack 2, the embodiment is implemented by a pushing member. Generally speaking, the pushing member is suitable for driving the buckle 41 to move away from the battery mounting rack 2, that is, as long as the buckle 41 can be driven to gradually separate from the battery mounting rack 2, so as to facilitate the battery mounting rack 2 to release the restraint of the buckle 41, the use requirement of the embodiment is met. For this, the embodiment is illustrated by a pushing member in the drawings. The pushing member is a pushing member 6 suitable for moving in the accommodating cavity 11 perpendicular to the movement direction of the buckle 41 to press the buckle 41, and one side end surface of the pushing member 6 is exposed at the opening 19. In this way, the pressing action on the pushing member 6 can be applied through the opening 19. Under the pressing action, the pushing member 6 moves in the accommodating cavity 11 to press the buckle 41, so that the buckle 41 moves away from the battery mounting rack 2 and the elastic member 42 is compressed. Then the buckle 41 and the battery mounting rack 2 are gradually separated, and the battery mounting rack 2 is gradually ejected from the accommodating cavity 11 under the elastic reset action of the elastic support 5.

[0062] Based on the above, it also needs to be explained that for the pushing member 6 and the buckle 41 in the accommodating cavity 11, in order to effectively utilize the internal space of the accommodating cavity 11, the movement trajectories of the two are perpendicular to each other. For this, the pushing member 6 and the buckle 41 are matched by the matching inclined surface K1. Based on this, in combination with an optional case illustrated by the drawings, the pushing member 6 is suitable for moving in the direction that the battery mounting rack 2 is pressed and assembled into the accommodating cavity 11. In this way, the movement trajectory of the buckle 41 in the accommodating cavity 11 is also perpendicular to the disassembly direction of the battery mounting rack 2 relative to the accommodating cavity 11.

[0063] On the basis of the above structure, when the ejector 6 is pressed through the opening 19 to move the ejector 6 towards the buckle 41, the buckle 41 moves away from the battery mounting rack 2 to gradually disengage the buckle 41 from the battery mounting rack 2, at this time the elastic member 42 is compressed, until the buckle 41 is completely disengaged from the battery mounting rack 2, the battery mounting rack 2 can be ejected from the receiving cavity 11 under the reset action of the elastic support 5. After the battery mounting rack 2 is ejected, the hand can release the ejector 6, at this time the ejector 6 and the buckle 41 can be restored to the original position under the reset action of the elastic member 42, that is, the reset action of the elastic member 42 in this embodiment is not only used for the reset of the buckle 41, but also for the reset of the ejector 6.

[0064] Furthermore, when the battery mounting rack 2 is press-fitted into the receiving cavity 11, the battery mounting rack 2 pushes the buckle 41 to move away from the battery mounting rack 2 and the elastic member 42 is compressed, and the buckle 41 is adapted to relatively approach the battery mounting rack 2 under the elastic reset action of the elastic member 42 to make the buckle 41 and the battery mounting rack 2 be clamped in place, and the battery mounting rack 2 pushes the elastic support 5 to deform.

[0065] Regarding the elastic support 5 used in this embodiment, in combination with the drawings, an optional case is exemplified, the elastic support 5 uses a torsion spring, and a support column 12 for matching the torsion spring is arranged in the receiving cavity 11, the torsion spring is sleeved on the support column 12 along its axis, and one end of the torsion spring is fixed in a support table in the receiving cavity 11, so that the other end of the torsion spring can be in abutting cooperation with the battery mounting rack 2.

[0066] In addition, it is also necessary to point out that regarding the clamping cooperation between the buckle 41 and the battery mounting rack 2, a clamping structure with concave-convex cooperation is arranged between the buckle 41 and the battery mounting rack 2. In this regard, in combination with the drawings, an optional case is exemplified, the clamping structure includes a groove 23 formed on the battery mounting rack 2 and a key 411 formed on the buckle 41 and adapted to be inserted into the groove 23. The shapes of the groove 23 and the key 411 here can be, for example, but not limited to, triangular.

[0067] Based on the above, it is also necessary to point out that the battery mounting rack 2 is also provided with a beveled pushing surface 22 for cooperating with the bevel K2 of the protrusion 411; the beveled pushing surface 22 is arranged on the wall surface of the battery mounting rack 2 beside the groove 23, so that when the battery mounting rack 2 is pressed into the accommodation cavity 11, the beveled pushing surface 22 first contacts the protrusion 411, and the beveled pushing surface 22 and the protrusion 411 are in bevel cooperation, so that when the battery mounting rack 2 is pressed into the accommodation cavity 11, the buckle 41 is relatively away from the battery mounting rack 2 and the elastic piece 42 is compressed. It can be understood that in an alternative embodiment, the cooperation bevel between the protrusion 411 and the beveled pushing surface 22 here can be parallel to the cooperation bevel of the pushing piece 6 and the buckle 41.

[0068] In addition, regarding the reliable cooperation between the battery mounting rack 2 and the accommodation cavity 11, the embodiment also makes the following design: the accommodation cavity 11 is also provided with guide strips 13 and guide ribs 14 parallel to each other; and the guide strips 13 and the guide ribs 14 extend in the direction in which the battery mounting rack 2 is pressed into the accommodation cavity 11, so that the guide strips 13 and the limiting ribs 16 form a limiting interval for guiding the two side end faces of the battery mounting rack 2.

[0069] Based on the above, furthermore, one end of the guide strip 13 is adapted to be inserted into the L-shaped buckle 412 of the buckle 41 to limit the end position of the buckle 41 when it is relatively close to the battery mounting rack 2 under the elastic resetting action of the elastic piece 42. Specifically, an L-shaped buckle 412 is arranged on the buckle 41 towards the battery mounting rack 2, and one end of the guide strip can be inserted into the L-shaped buckle 412. Through the limiting of the guide strip 13, when the L-shaped buckle 412 and the guide strip 13 are buckled in place, the buckle 41 cannot continue to move towards the battery mounting rack 2 side under the action of the elastic piece 42.

[0070] And in order to better limit the movement trajectory of the buckle 41 in the accommodation cavity 11, the accommodation cavity 11 of the embodiment is also provided with limiting walls 15 and limiting ribs 16 parallel to each other; and the limiting walls 15 and the limiting ribs 16 extend in the direction in which the buckle 41 is relatively away from and close to the battery mounting rack 2, so that the limiting walls 15 and the limiting ribs 16 form a guide interval for limiting the two side end faces of the buckle 41. The limiting wall 15 is located on the side of the buckle 41 away from the pushing piece 6.

[0071] Regarding the limiting problem of the movement trajectory of the pushing piece 6 in the receiving cavity 11, the embodiment is designed as follows: the pushing piece 6 is provided with a limiting table 61, and the receiving cavity 11 is provided with a limiting portion 17 adapted to abut against the limiting table 61; the limiting portion 17 and the buckle 41 are located on the two sides of the limiting table 61 along the movement direction of the pushing piece 6. Based on this condition, when the battery mounting rack 2 is buckled in place with the buckle 41, the limiting table 61 abuts against the limiting portion 17, so that the pushing piece 6 cannot be separated from the opening 19 of the receiving cavity 11.

[0072] In summary, regarding the self-ejection type battery assembly of the embodiment, the dismounting process of the battery 3 is as follows:

[0073] The user presses the pushing piece 6 in the direction of pressing and installing the battery mounting rack 2 into the receiving cavity 11, so as to further move the pushing piece 6 to the inside of the receiving cavity 11; during the pushing process, the pushing piece 6 constantly presses the buckle 41 through the inclined surface K1, so that the buckle 41 is subjected to a force f as shown in the figure, wherein the component force f2 is blocked by the limiting wall 15, and f1 will make the buckle 41 compress the elastic piece 42 and move away from the battery mounting rack 2, so that the buckle 41 is gradually separated from the battery mounting rack 2, and the battery mounting rack 2 is gradually ejected from the receiving cavity 11 under the elastic return action of the elastic support 5. Figure 12

[0074] When the battery mounting rack 2 with the battery 3 placed therein is installed into the receiving cavity 11, as the battery mounting rack 2 is pushed in, the battery mounting rack 2 gradually contacts the elastic support 5, so that the elastic support 5 is gradually deformed, the inclined pushing surface 22 of the battery mounting rack 2 first contacts the wall surface matched with the inclined pushing surface 22 of the convex key 411, so that the battery mounting rack 2 gradually deepens into the receiving cavity 11, and the buckle 41 first moves away from the battery mounting rack 2, and the force borne by the buckle 41 after being subjected to the pushing force of the battery mounting rack 2 is as shown in the figure, wherein the total force F perpendicular to the wall surface matched with the inclined pushing surface 22 of the convex key 411 is divided into two component forces F1 and F2 in two directions, F2 is blocked by the limiting wall 15, and F1 drives the buckle 41 to compress the elastic piece 42 and move away from the battery mounting rack 2. Figure 11

[0075] Embodiment 2:

[0076] Please refer to Figures 13 to 19 ​​As shown, on the basis of the self-ejecting battery assembly of Embodiment 1, the self-ejecting battery assembly provided in the present embodiment has the same structural principle as that of Embodiment 1, and the difference lies in that the pushing member used in the present embodiment is different in structure and use mode from that of Embodiment 1. Specifically, the pushing member used in the present embodiment is a knob 200 connected with the buckle 41 and adapted to move synchronously with the buckle 41, and the side end face of the knob 200 exposed at the opening 19 is similar to the case of the jacking member 6 of Embodiment 1, that is, the human finger can exert force on the knob 200 through the opening 19.

[0077] Based on the above, in addition, the movement mode of the knob 200 in the accommodation cavity 11 in the present embodiment is the same as and synchronous with that of the buckle 41. To facilitate processing and improve the synchronism of the movement of the buckle 41 and the knob 200, the knob 200 and the buckle 41 are integrally processed and formed, so that they form an integral piece to move synchronously. To this end, the anti-slip pattern 201 is arranged on the end face of the knob 200 in contact with the human finger, so that the human finger is more easy to operate when exerting force on the knob 200.

[0078] On the basis of the above structure, in an alternative embodiment, the knob 200 is generally in the shape of an L structure, which can form a space for the limiting rib 16, so that the design of the limiting rib 16 does not affect the movement of the knob 200 in the accommodation cavity 11.

[0079] In addition, it also needs to be pointed out that, in order to accurately control the movement trajectory of the knob 200 under the action of the human finger, so as to ensure that the buckle 41 can move away from the battery mounting frame 2 under the action of the knob 200 to make the battery mounting frame 2 lose the binding effect of the buckle 41, the present embodiment further provides a guide block 110 on the inner wall of the accommodation cavity 11 to limit the movement trajectory of the knob 200, and a guide groove 202 is formed on the knob 200 to adapt to the guide block 110.

[0080] In summary, for the self-ejecting battery assembly of the present embodiment, the knob 200 and the buckle 41 are in an integral structure, which can simplify the structure of the overall self-ejecting battery assembly, thereby facilitating assembly.

In this structure, combined with the drawings, for example, a U-shaped structure is used, for example, but not limited to, for the battery 3 placed in the limiting bin 21, the negative electrode of the battery 3 faces the hollow opening 24, so that the negative spring 72 is in contact with the negative electrode of the battery 3 through the hollow opening 24, and the positive spring 71 directly presses on the positive electrode of the battery 3.

[0084] In summary, for the switch device of the embodiment, the process of disassembling and connecting the battery 3 and the PCB 7 does not require additional operation process, and only needs to be naturally completed during the process of the battery 3 relative to the accommodating cavity 11 or being pressed into the accommodating cavity 11, so that the convenience of disassembling and assembling the battery 3 is improved, and the normal use of the battery 3 is ensured.
