Description

Technical Field

[0001] This invention belongs to the field of battery mounting structures, and specifically relates to a self-locking pop-out battery box mechanism. Background Technology

[0002] With the continuous development of technology and the improvement of living standards, the number of electronic products used is increasing. Many electronic products use DC power from batteries for ease of installation and use. However, batteries have limited power and need to be replaced when they are depleted. Currently, the most common battery fixing methods are screws or other methods that require screwdrivers or other specific tools for disassembly. Replacing the battery requires these tools, which is cumbersome and inconvenient in daily use, reducing the user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a self-locking pop-out battery box mechanism to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a self-locking pop-out battery box mechanism, comprising a battery box, an elastic component, a housing, and a self-locking component. The housing has an open battery compartment, and the battery box is movably inserted into the battery compartment through the open opening. The elastic component is used to apply an elastic force to the battery box to pop it out of the battery compartment. The self-locking component is configured such that when the battery box is in the unlocked state, a pushing force is applied to overcome the elastic force of the elastic component and move it into the battery compartment to a predetermined position, and the pushing force is removed, the battery box is restricted from moving out of the opening to complete the self-locking; when the battery box is in the self-locked state, a pushing force is applied to overcome the elastic force of the elastic component and move it into the battery compartment to a predetermined position, and the pushing force is removed, the restriction on the battery box moving out of the opening is released to complete the unlocking.

[0005] Furthermore, the self-locking component includes a self-locking pin and a sliding circuit. A direction perpendicular to the battery box insertion is defined as the left-right direction. The self-locking pin is movably disposed within the battery compartment. The sliding circuit is disposed on the outer side of the battery box and includes a self-locking guide groove, a locking groove, and an unlocking guide groove. When the battery box is in the unlocked state and is pushed against the elastic force of the elastic component to move into the battery compartment to a predetermined position, and the pushing force is removed, the self-locking pin slides along the self-locking guide groove to the locking groove to complete the self-locking. When the self-locking pin is in the locking groove, if the battery box is pushed against the elastic force of the elastic component to move into the battery compartment to a predetermined position again, and the pushing force is removed, the self-locking pin slides from the locking groove along the unlocking guide groove to disengage from the sliding circuit.

[0006] Furthermore, the unlocking guide slide includes a first unlocking guide slide and a second unlocking guide slide. When the self-locking pin is in the locking groove, if the battery box is pushed again to overcome the elastic force of the elastic component and move into the battery compartment to a predetermined position, the self-locking pin slides from the locking groove along the first unlocking guide slide to the second unlocking guide slide. The second unlocking guide slide is a straight groove and is set along the insertion direction of the battery box.

[0007] Furthermore, the slide circuit also includes a guide groove. The first end of the guide groove extends through to the inner end face of the battery box to form a notch, allowing the self-locking pin to slide in and out of the guide groove. The second end of the guide groove is simultaneously connected to the inlet of the self-locking guide slide groove and the outlet of the second unlocking guide slide groove. The bottom of the outlet end of the second unlocking guide slide groove is higher than the bottom of the second end of the guide groove and the bottom of the inlet end of the self-locking guide slide groove, forming a limiting protrusion.

[0008] Furthermore, the guide groove is a straight groove, set along the insertion direction of the battery box, and the guide groove and the second unlocking guide groove are connected to form a straight groove structure.

[0009] Furthermore, it also includes a U-shaped needle, which is disposed outside the housing. The first end of the U-shaped needle is rotatably disposed on the housing. The housing has an arc-shaped groove that extends through the battery compartment and is arranged in the left-right direction. The second end of the U-shaped needle moves through the arc-shaped groove and extends into the battery compartment to form a self-locking needle.

[0010] Furthermore, the housing is also provided with a retainer, which is used to keep the self-locking pin, which has disengaged from the slide circuit, in its initial state.

[0011] Furthermore, the retaining element is implemented using a permanent magnet, and the U-shaped needle is made of magnetic material.

[0012] Furthermore, it also includes a limiting component, which is fixedly mounted on the housing to restrict the movement of the U-shaped needle away from the housing.

[0013] Furthermore, the elastic component is implemented using a spring.

[0014] Beneficial technical effects of the present invention:

[0015] This invention allows for battery removal and replacement without the need for specific tools, making battery replacement convenient, improving user experience, and is simple in structure and easy to implement. Attached Figure Description

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figure 1-9As shown, a self-locking pop-out battery box mechanism includes a battery box 1, an elastic component 2, a housing 3, and a self-locking component. The housing 3 has an open battery compartment 31. The battery box 1 is movably inserted into the battery compartment 31 through the open opening. The elastic component 2 is used to apply an elastic force to the battery box 1 to pop it out of the battery compartment 31. The self-locking component is configured to, when the battery box 1 is in the unlocked state, be pushed against the elastic force of the elastic component 2 and moved into the battery compartment 31 to a predetermined position, and the pushing force is removed, restrict the battery box 1 from moving out of the opening to complete the self-locking; when the battery box 1 is in the self-locked state, be pushed against the elastic force of the elastic component 2 and moved into the battery compartment 31 to a predetermined position, and the pushing force is removed, release the restriction on the battery box 1 from moving out of the opening to complete the unlocking.

[0029] Specifically, in this embodiment, the self-locking assembly includes a self-locking pin 4 and a sliding groove circuit 5, defining a direction perpendicular to the insertion of the battery box 1 as the left-right direction. Figure 3 The self-locking pin 4 is movable left and right inside the battery compartment 31 (in the left and right direction). The sliding groove circuit 5 is located on the outer side of the battery box 1. In this specific embodiment, the sliding groove circuit 5 is located on the back of the battery box 1. Correspondingly, the self-locking pin 4 is movable left and right on the compartment wall of the battery compartment 31 opposite to the back of the battery box 1. The structure is reasonably compact and easy to implement, but it is not limited to this. In some embodiments, the sliding groove circuit 5 can also be located at other positions on the outer side of the battery box 1.

[0030] The sliding circuit 5 includes a self-locking guide slide 51, a locking groove 52, and an unlocking guide slide 53. When the battery box 1 is in the unlocked state and is pushed against the elastic force of the elastic component 2 to move into the battery compartment 21 to a predetermined position, and the pushing force is removed, the self-locking pin 4 slides along the self-locking guide slide 51 into the locking groove 52, thus restricting the battery box 1 from continuing to move out of the opening of the battery compartment 21, completing the self-locking; when the self-locking pin 4 is in the locking groove 52, such as Figure 8 As shown, if the battery box 1 is pushed again to overcome the elastic force of the elastic component and moves into the battery compartment 31 to the predetermined position and the push is removed, the self-locking pin 4 slides from the locking groove 52 along the unlocking guide slide 53 to disengage from the slide circuit 5, thereby unlocking.

[0031] In this specific embodiment, the unlocking guide groove 53 includes a first unlocking guide groove 531 and a second unlocking guide groove 532. When the self-locking pin 4 is in the locking groove 52, if the battery box 1 is pushed again to overcome the elastic force of the elastic component 2 and moves into the battery compartment 31 to a predetermined position, the self-locking pin 4 slides from the locking groove 52 along the first unlocking guide groove 531 to the second unlocking guide groove 532. Figure 9As shown, the second unlocking guide groove 532 is a straight groove, which is set along the insertion direction of the battery box 1 to ensure that under the push of the elastic force of the elastic component 2, the self-locking pin 4 can easily slide along the second unlocking guide groove 532 to disengage from the groove circuit 5 and achieve reliable unlocking. However, it is not limited to this. In some embodiments, the second unlocking guide groove 532 can also be set at an angle along the insertion direction of the battery box 1.

[0032] In this specific embodiment, the locking groove 52 is a groove that bends toward the opening of the battery compartment 31. It has a stable locking effect and a simple and easy-to-implement structure, but it is not limited to this.

[0033] In this specific embodiment, the slide circuit 5 further includes a guide groove 54. The first end of the guide groove 54 extends through to the inner end face of the battery box 1, forming a notch 541, which allows the self-locking pin 4 to slide into or out of the guide groove 54 through the notch 541. The second end of the guide groove 54 is simultaneously connected to the inlet of the self-locking guide slide 51 and the outlet of the second unlocking guide slide 532. The bottom of the outlet end of the second unlocking guide slide 532 is higher than the bottom of the second end of the guide groove 54 and the bottom of the inlet end of the self-locking guide slide 51, forming a limiting protrusion 55. The limiting protrusion 55 is used to restrict the self-locking pin 4 from sliding from the guide groove 54 into the self-locking guide slide 51. The bottom of the second end of the guide groove 54 and the bottom of the inlet end of the self-locking guide slide 51 are smoothly connected, preferably forming the same plane, which provides a better guiding effect.

[0034] By setting the guide groove 54, the position of the self-locking pin 4 after disengaging from the guide groove 54 is the same as the position in the initial state, which improves stability and reliability, and the structure is simple and easy to implement.

[0035] Preferably, in this specific embodiment, the guide groove 54 is a straight groove, which is set along the insertion direction of the battery box 1. The guide groove 54 and the second unlocking guide slide 532 are connected to form a straight groove structure, which ensures that under the elastic force of the elastic component 2, the self-locking pin 4 can easily slide along the second unlocking guide slide 532 and the guide groove 54 to disengage from the slide circuit 5, thereby achieving reliable unlocking, but it is not limited to this.

[0036] In this specific embodiment, a U-shaped needle 6 is also included. The U-shaped needle 6 is disposed outside the housing 3. The first end 61 of the U-shaped needle 6 is rotatably inserted into the housing 3. The housing 3 is provided with an arc-shaped groove 32 that extends through the battery compartment 31 and is arranged in the left-right direction. The second end 62 of the U-shaped needle 6 is movably inserted through the arc-shaped groove 32 and extends into the battery compartment 31 to form a self-locking needle 4. This structure is simple and easy to process and assemble, but it is not limited to this. In some embodiments, the self-locking needle 4 can also be implemented using other existing structures, such as providing a sliding groove on the wall of the battery compartment 31, and the self-locking needle 4 is directly slidably disposed in the sliding groove, etc.

[0037] Furthermore, in this embodiment, the housing 3 is also provided with a retainer 7, which is used to keep the self-locking pin 4, which is disconnected from the slide circuit 5, in its initial state, to prevent the self-locking pin 4 from wobbling left and right and failing to align with the notch 541, thereby improving stability and reliability.

[0038] Preferably, in this specific embodiment, the retaining member 7 is implemented using a permanent magnet, and the U-shaped needle 6 is made of magnetic material. The structure is simple, easy to implement, and low in cost. However, it is not limited to this. In some embodiments, the retaining member 7 can also be implemented using other existing reset members, such as elastic members.

[0039] Preferably, in this specific embodiment, the retainer 7 is implemented using a magnet, which is easy to implement and low in cost, but it is not limited thereto. The U-shaped needle 6 is made of iron material, which is not easily damaged, has a long service life, and is easy to implement and low in cost, but it is not limited thereto.

[0040] Furthermore, in this specific embodiment, a limiting member 8 is also included. The limiting member 8 is fixedly disposed on the housing 3 to restrict the movement of the U-shaped needle 6 away from the housing 3, prevent the self-locking needle 4 from disengaging from the slide rail circuit, and even prevent the retaining member 7 from disengaging from the housing 3 and falling off, thereby improving stability and reliability.

[0041] Preferably, in this specific embodiment, the limiting member 8 is made of stainless steel needle. The two ends of the limiting member 8 are fixed on the housing 3. The limiting member 8 is located on the other side of the U-shaped needle 6 facing away from the housing 3. This structure is simple and easy to implement, but it is not a limitation.

[0042] In this specific embodiment, the elastic component 2 is implemented using a spring, preferably a compression spring, which has a simple structure, is easy to implement, and has low cost. The elastic component 2 is disposed between the inner end face of the battery box 1 and the bottom of the battery compartment 31. However, this is not a limitation; in some embodiments, other existing elastic components can also be used.

[0043] In some embodiments, the elastic component 2 can also serve as an electrical connection component for the battery within the battery box 1.

[0044] In this specific implementation, housing 3 is the control box housing, but it is not limited to this.

[0045] When installing battery box 1, insert battery box 1 into battery compartment 31 through the opening of battery compartment 31, and press it inward against the elastic force of elastic component 2. During the pressing process, self-locking pin 4 first slides from notch 541 into guide groove 54, such as... Figure 5 As shown, after sliding to the second end of the guide groove 54, due to the limiting protrusion 55, the self-locking pin 4 then slides into the self-locking guide groove 51, as... Figure 6 As shown, when the self-locking pin 4 continues to slide to the foremost position (predetermined position) of the self-locking guide groove 51, as... Figure 7As shown, battery box 1 cannot move further into battery compartment 31. Then, the pushing force on battery box 1 is removed, and battery box 1 moves outward and pops out under the elastic force of elastic component 2. Self-locking pin 4 continues to slide along self-locking guide groove 51 into locking groove 52 and gets stuck, preventing battery box 1 from moving further outward. Figure 8 As shown, self-locking is completed.

[0046] When disassembling battery box 1, the elastic force of elastic component 2 is overcome by pressing battery box 1 inward, causing battery box 1 to move into battery compartment 31. The self-locking pin 4 slides from locking groove 52 along the first unlocking guide groove 531 to the second unlocking guide groove 532 (predetermined position). Figure 9 As shown, at this point, the battery box 1 can no longer move into the battery compartment 31. Then, the pushing force on the battery box 1 is removed, and the battery box 1 moves outward and pops out under the elastic force of the elastic component 2. The self-locking pin 4 continues to slide along the second unlocking guide groove 532 and guide groove 54 until it is separated from the groove circuit 5 by the notch 541, thus completing the unlocking. The battery box 1 pops out of the battery compartment 31 under the push of the elastic force of the elastic component 2, thus completing the unlocking.

[0047] This invention allows for battery removal and replacement without the need for specific tools, making battery replacement convenient, improving user experience, and is simple in structure and easy to implement.

[0048] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
