Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and specifically to a battery cap screw-on stop mechanism. Background Technology

[0002] With the rapid development of electronic technology, modern electronic devices are trending towards integration, miniaturization, and portability. The power supply solutions for these devices are mainly divided into two categories: one is a built-in battery; the other is a replaceable standard battery. Compared to the built-in battery solution, the replaceable battery mode has a significant advantage in battery life, theoretically achieving near-infinite battery life through continuous battery replacement, and is therefore widely used in various fields.

[0003] However, in some applications with stringent data continuity requirements, devices need to replace batteries while in operation to avoid data loss. Therefore, a dual-battery parallel power supply architecture is often used, requiring users to replace batteries one by one according to the operating procedures. In practical applications, it has been found that due to differences in operating habits or negligence in emergency situations, users often mistakenly unscrew the caps of both sets of batteries at the same time to replace them, causing the device to lose power instantly, which in turn leads to data loss, interruption of critical processes, and other consequences.

[0009] Optionally, the locking assembly further includes an axial fixing assembly, the axial fixing assembly comprising: A waist-shaped countersunk hole is formed through the slider body; Screw holes are provided at the top of the housing and correspond to the position of the countersunk hole. A countersunk screw, wherein the threaded end of the countersunk screw moves through the oblong countersunk hole and is threadedly connected to the screw hole.

[0010] Optionally, the axial fixing assembly is provided in two sets, with the two sets of axial fixing assemblies distributed on both sides of the magnetic positioning assembly.

[0011] Optionally, the opening end of the battery compartment is provided with an internal thread, and the lower end of the battery cap is provided with an external thread that matches the internal thread.

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] Furthermore, the terms "first," "second," and similar words used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "comprising" indicate that the element preceding the word encompasses the element listed after the word, and do not exclude the possibility of encompassing other elements as well.

[0021] like Figure 1As shown, this utility model provides a battery cap 2 stop mechanism, including a housing 1, two sets of battery caps 2 and a locking component 3. The housing 1 includes two sets of battery compartments 11 symmetrically distributed along the length of the housing 1. The two sets of battery caps 2 are rotatably connected to the opening ends of the corresponding battery compartments 11, and the outer circumferential surface of the battery caps 2 is provided with a plurality of slots 23 evenly distributed along the circumference. The locking component 3 is slidably disposed on the top of the housing 1 and located between the two sets of battery caps 2, for sliding to lock one set of battery caps 2 and disengage from the locking engagement with the other set of battery caps 2.

[0022] In the technical solution provided by this utility model, by setting the locking component 3 on the top of the housing 1 and slidably disposed between the two battery caps 2, the locking component 3 can switch between a first position and a second position. In the first position, one end of the locking component 3 disengages from the slot 23 of one battery cap 2, and the other end of the locking component 3 is inserted into the slot 23 of the other battery cap 2 to restrict the other battery cap 2 from rotating relative to the housing 1. In the second position, the other end of the locking component 3 disengages from the slot 23 of the other battery cap 2, and one end of the locking component 3 is inserted into the slot 23 of one battery cap 2 to restrict the one battery cap 2 from rotating relative to the housing 1.

[0023] It should be noted that if a special situation occurs and the locking component 3 in the battery cap 2 stop mechanism provided by this utility model happens to stop in the middle position, it will lock the battery caps 2 on both sides at the same time, and the locking component 3 needs to be moved to slide again.

[0024] It is understood that the outer shell 1 in this utility model serves as a basic support structure, providing space for the battery compartment 11 and the locking component 3. The two sets of battery caps 2 are respectively installed at the opening ends of the two battery compartments 11 to realize the closing and opening of the battery. The locking component 3 is responsible for controlling the locking and unlocking states of the battery caps 2.

[0025] Specifically, the outer casing 1 has two sets of battery compartments 11 symmetrically arranged along its length. The shape and size of the battery compartments 11 are designed according to the specifications of the batteries installed. For example, if cylindrical batteries are installed, the battery compartment 11 can be designed as a cylindrical cavity that matches the diameter and length of the battery. If button batteries are installed, it can be designed as a corresponding circular or square shallow groove.

[0026] It is understandable that a connection structure matching the battery cap 2 is provided at the opening of the battery compartment 11. This connection structure can be any suitable connection structure, as long as it ensures that the battery cap 2 can be tightly connected to it after rotation. Figure 4As shown, in some embodiments, the opening end of the battery compartment 11 is provided with an internal thread 14, and the lower end of the battery cap 2 is provided with an external thread 21 that matches the internal thread 14. That is, the opening end of the battery compartment 11 and the battery cap 2 can be tightly connected to the battery compartment 11 by screwing the threads together.

[0027] The slots 23 are evenly distributed along the circumference of the battery cap 2, and their number can be determined according to actual needs. The structure of the slots 23 can be any suitable structure, as long as it facilitates the insertion and removal of the locking component 3, such as... Figure 3 As shown, in some embodiments, the upper end of the external thread 21 of the battery cap 2 is provided with toothed protrusions 22 that are evenly distributed in the circumferential direction, and the gap between two adjacent toothed protrusions 22 forms a slot 23.

[0028] The toothed protrusions 22 increase the structural strength of the battery cap 2 to some extent. Since the slot 23 is naturally formed by the gap between two adjacent toothed protrusions 22, the manufacturing process only requires machining the toothed protrusions 22 as required, reducing manufacturing difficulty. The toothed protrusions 22 can be rectangular, trapezoidal, or similar shapes.

[0029] In this utility model, such as Figure 4 As shown, the locking component 3 includes two limiting strips 31 and a sliding block. The two limiting strips 31 are arranged parallel to each other and spaced apart on the top of the housing 1, and the two ends of the limiting strips 31 extend toward the two sets of battery caps 2 respectively. The sliding block is slidably connected to the two limiting strips 31.

[0030] Two parallel and spaced-apart limit bars 31 form a groove for the sliding block to slide along a specific direction, providing accurate sliding guidance for the sliding block. It can be understood that the length of the groove, i.e. the length of the limit bar 31, can be determined according to the sliding range of the sliding block between the first position and the second position.

[0031] Specifically, such as Figure 5 As shown, the sliding block includes a slider body 32 and two stop protrusions 33. The two stop protrusions 33 are respectively disposed at both ends of the slider body 32 for engaging and locking with the corresponding slots 23 of the battery cap 2. It is understood that the shape of the stop protrusions 33 can be any suitable shape, as long as it can be inserted into the slots 23 to restrict the rotation of the battery cap 2 relative to the outer casing 1. For example, the stop protrusions 33 can be cylindrical, cuboid, etc.

[0032] In this utility model, combined with Figure 2 , Figure 4 as well as Figure 6As shown, the locking assembly 3 also includes a magnetic positioning assembly. Specifically, the magnetic positioning assembly includes a first magnet fixing groove 34, which is opened in the bottom center area of ​​the slider body 32; a second magnet fixing groove 12, which is opened in the top of the outer shell 1 and corresponds to the position of the first magnet fixing groove 34; a first magnet 35, which is located in the center of the first magnet fixing groove 34; and two second magnets 13, which are symmetrically arranged on the two opposite inner walls of the second magnet fixing groove 12, and the opposite faces of the second magnets 13 and the first magnets 35 are opposite poles.

[0033] Understandably, the opposing surfaces of the first magnet 35 and the second magnet 13 are opposite poles and attract each other. Due to the attraction of the magnets, the position of the slider usually has only two definite locked positions: the first position and the second position. This positioning method avoids uncertain shaking or displacement of the slider in the middle position. In the first position, the magnetic attraction firmly fixes the slider to the corresponding side, ensuring that the stop protrusion 33 at one end can be accurately inserted into the slot 23 of the battery cap 2 on that side, while the stop protrusion 33 at the other end disengages from the slot 23 of the battery cap 2 on the other side, thus achieving accurate positioning of the slider.

[0034] When locking and unlocking the battery cap 2, the operator only needs to push the sliding block in the opposite direction to unlock one side of the battery cap 2. The change in magnetic force easily positions and locks the sliding block. Moreover, it eliminates the need for complex mechanical structures, simplifying the overall structure of the battery cap 2 stopping mechanism. Magnets, as mature and stable components, have a long service life and good environmental adaptability, maintaining stable performance under various harsh conditions and ensuring the long-term reliable operation of the battery cap 2 stopping mechanism.

[0035] In this utility model, combined with Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the locking assembly 3 also includes an axial fixing assembly, which includes a waist-shaped countersunk hole 36 that is opened through the slider body 32; a screw hole 37 that is opened on the top of the housing 1 and corresponds to the position of the waist-shaped countersunk hole 36; and a plug screw 38 whose threaded end moves through the waist-shaped countersunk hole 36 and is threadedly connected to the screw hole 37.

[0036] The countersunk hole 36 on the slider body 32 is positioned opposite to the corresponding screw hole 37 on the top of the outer casing 1. The threaded end of the push-button screw 38 passes through the countersunk hole 36 and is screwed into the screw hole 37. Due to the shape of the countersunk hole 36, after the push-button screw 38 is screwed into the screw hole 37, its nut portion is engaged on the step of the countersunk hole 36, while the threaded end is tightly connected to the screw hole 37, thus fixing the slider body 32 and the outer casing 1 axially. This fixing method works in conjunction with the magnetic positioning component; the magnetic attraction ensures the stable position of the slider in the horizontal direction, while the axial fixing component prevents the slider from detaching from the outer casing 1 perpendicular to the sliding direction. It is understandable that the position of the countersunk hole 36 relative to the push-button screw 38 changes during the movement of the slider, but because the countersunk hole 36 has a certain length range, the push-button screw 38 will not obstruct the normal sliding of the slider.

[0037] Furthermore, in order to make the sliding block more stable in the axial direction and prevent it from easily falling off the top of the housing 1, in some embodiments, two sets of axial fixing components are provided, and the two sets of axial fixing components are distributed on both sides of the magnetic positioning component.

[0038] In this utility model, such as Figure 5 As shown, to make it easier for operators to find the point of application when sliding the slider with their fingers, in some embodiments, the top of the slider body 32 is provided with a toggle part 39, which is a raised structure. Furthermore, the surface of the raised structure is provided with anti-slip texture. The anti-slip texture further enhances the friction between the finger and the toggle part 39, preventing the finger from slipping during the sliding process and improving the ease of operation.

[0039] In summary, the battery cap stop mechanism provided by this utility model can effectively prevent the device from losing power instantly due to misoperation when replacing batteries in dual-battery devices. Moreover, the overall structure is compact, saves space, is lightweight, and is easy to operate.

[0040] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
