Technical Field

[0001] The utility model relates to the field of battery protection, in particular to a battery replacement structure and an information display screen. Background Art

[0002] With the maturity of electronic technology, electronic devices are increasingly widely used. Especially portable electronic devices (such as personal digital assistant devices (PDAs), mobile phones, tablet computers, etc.) and electronic devices fixed outdoors (such as information display screens) usually use batteries as their energy source. During the use of the battery, due to problems such as battery damage, the battery capacity decreasing over time, and the battery charging method (the electronic device does not have a charging interface), a battery replacement structure needs to be provided for replacing the battery.

[0003] Existing battery replacement structures mainly include screw fixing structures, sealing structures, and snap-fit structures. The screw fixing structure usually arranges a number of threaded holes on the outer periphery of the battery accommodation cavity. After the battery cover covers the battery accommodation cavity, the screw and the threaded hole are threadedly connected; when replacing the battery, the screw fixing structure requires a screwdriver to disassemble and assemble the screws one by one, which consumes a lot of time and labor and the threads are easily damaged. The sealing structure mainly uses materials such as sealant to bond the battery accommodation cavity and the battery cover; when replacing the battery, the sealing structure requires a professional to use professional debonding tools for disassembly and assembly, which has problems such as repair complexity and difficulty, and consumes a lot of time and labor. The existing snap-fit structure usually snap-fits the battery accommodation cavity and the battery cover, and it usually has a protrusion on the side wall or surface of the battery cover or the battery accommodation cavity. When replacing the battery, by pressing or pulling the protrusion, the battery accommodation cavity and the battery cover are disassembled and assembled. However, its disassembly and assembly are too easy, and during use, the connection between the battery cover and the battery accommodation cavity may become loose due to friction or accidental collision, causing the battery to lose a stable connection and affecting the normal operation of the device; there is even a risk that users may replace the battery themselves, and may incorrectly insert an inappropriate battery or insert the battery in the reverse direction, resulting in damage to the device or the battery itself, and even posing a threat to the safety of users. Summary of the Utility Model

[0004] Therefore, a battery replacement structure is needed to solve the problem that the existing snap-fit structure is prone to misoperation and causes the battery cover to accidentally open.

[0005] To achieve the above object, the utility model provides a battery replacement structure, which includes a battery accommodation cavity, a battery cover, and a battery. A card slot is provided in the battery accommodation cavity, and a buckle corresponding to the card slot is provided on the battery cover; when the battery cover covers the battery accommodation cavity, the buckle and the card slot are snap-fitted; the battery is placed in the battery accommodation cavity; there is a hole on the battery cover.

[0006] Further, the battery is provided on the battery cover, and the hole is located on the side of the battery.

[0007] Furthermore, the battery cover is provided with a battery slot on one side corresponding to the battery accommodating cavity, and a battery buckle is provided on the side wall of the battery slot. When installing, the battery is placed in the battery slot, and the battery buckle is buckled on the side of the battery facing away from the battery slot.

[0008] Furthermore, there are a plurality of battery buckles, and the battery buckles are equally distributed along the circumference of the side wall of the battery slot.

[0009] Furthermore, the battery has at least two.

[0010] Furthermore, every two adjacent batteries form a group of battery cells; each group of battery cells has two positive plates and one negative plate corresponding to it in the battery accommodating cavity; the two positive plates are arranged corresponding to the positive poles of the battery, and when the battery is placed in the battery accommodating cavity, the positive pole of the battery is connected to the corresponding positive plate; the negative plate is arranged between two adjacent batteries in a group; poles are respectively arranged at one end of the negative plate corresponding to the negative poles of the two adjacent batteries, and the other end has at least one surface segment for connecting the two poles; when the battery is placed in the battery accommodating cavity, the two poles are connected to the corresponding negative poles of the battery.

[0011] Furthermore, the battery cover is provided with a battery slot on one side corresponding to the battery accommodating cavity, and a battery buckle is provided on the side wall of the battery slot. When installing, the battery is placed in the battery slot, and the battery buckle is buckled on the side of the battery away from the battery slot;

[0012] The battery slot is provided with notches corresponding to the two poles.

[0013] Furthermore, when the battery cover covers the battery accommodating cavity, the battery cover is placed in the battery accommodating cavity.

[0014] An information display screen applies the above-mentioned battery replacement structure.

[0015] Different from the prior art, the above technical solution disassembles the battery cover and the battery accommodating cavity by setting a hole, thereby avoiding exposing the protrusion on the outer surface of the battery accommodating cavity, and preventing the battery cover from being accidentally opened due to misoperation. At the same time, it prevents non-professionals from opening the battery cover at will and avoiding them from contacting the battery or operating the battery system, thereby reducing potential dangers and accident risks, ensuring the stable operation of the battery system and avoiding accidental power outages, and effectively protecting the safety of the battery; in addition, no cumbersome operations are required during maintenance, and only a tool needs to be inserted through the hole to hook the battery cover, and a pulling force needs to be applied to the battery cover to disassemble it.

[0044] See Figures 1-5 As shown, the present utility model provides a battery replacement structure, including a battery accommodation cavity 10, a battery cover 20, and a battery 30. A card slot 101 is provided in the battery accommodation cavity 10, and a buckle 201 corresponding to the card slot 101 is provided on the battery cover 20; when the battery cover 20 covers the battery accommodation cavity 10, the buckle 201 and the card slot 101 are snap-connected; the battery 30 is placed in the battery accommodation cavity 10; a hole 202 is provided on the battery cover 20.

[0045] See Figure 1 and Figure 2 As shown, when the above battery cover 20 covers the battery accommodation cavity 10, it is ensured that the buckle 201 can accurately insert into the card slot 101 and be snap-connected with the card slot 101; the buckle 201 has a certain elastic deformation ability. The connection method between the buckle 201 and the card slot 101 makes the battery 30 replacement process more efficient, can complete the battery 30 replacement faster, and reduces the waste of time and energy; the above hole 202 is provided on the battery cover 20 for disassembling the battery cover 20; when replacing the battery 30, by using a tool (hook-like) to extend into the battery cover 20 through the hole 202, the tool hooks the battery cover 20 and provides a pulling force (the pulling force is greater than the resistance generated by the buckle 201 in the card slot 101) to disassemble the battery cover 20 and the battery accommodation cavity 10. After replacing the battery 30, the battery cover 20 is covered on the battery accommodation cavity 10, and the buckle 201 is snap-connected with the card slot 101; when snap-connected, no opening and closing protrusion is exposed on the outer surface of the battery accommodation cavity 10.

[0046] By the above method of providing a hole 202, the battery cover 20 is separated from the battery accommodation cavity 10, avoiding the exposure of the protruding part on the outer surface of the battery accommodation cavity 10, preventing the accidental opening of the battery cover 20 due to misoperation, and at the same time preventing non-professionals from randomly opening the battery cover 20, avoiding their contact with the battery 30 or operation of the battery system, reducing the potential risks and accident risks, ensuring the stable operation of the battery system and avoiding accidental power off, effectively protecting the safety of the battery 30; in addition, during maintenance, there is no need for cumbersome operations. Only need to use a tool to extend through the hole 202 and hook the battery cover 20, and apply a pulling force to the battery cover 20 to separate it.

[0047] See 3 and Figure 4 As shown, the battery 30 is provided on the battery cover 20, and the hole 202 is located on the side of the battery 30. Providing the battery 30 on the battery cover 20 means providing the battery 30 on the side of the battery cover 20 corresponding to the battery accommodation cavity 10. When the battery cover 20 is closed on the battery accommodation cavity 10, the battery 30 is located inside the battery accommodation cavity 10. When replacing the battery 30, only need to open the battery cover 20 and take out the entire battery cover 20 and the battery 30 as a whole for replacement. Compared with the design of placing the battery 30 inside the battery accommodation cavity 10 (without taking out the old battery 30 inside the battery accommodation cavity 10 and then putting in a new battery), it is more convenient and faster, realizing convenient replacement of the battery 30, and there is no risk of wrongly inserting an inapplicable battery 30 or inserting the battery 30 in reverse. At the same time, it also makes maintenance and repair more convenient. When the battery 30 fails or needs to be replaced, only need to replace the battery cover 20, without the need for complex disassembly and assembly of the equipment, which helps to improve the maintainability and repair efficiency of the equipment.

[0048] The above-mentioned battery 30 is provided on the battery cover 20 to prevent the battery 30 from falling off the battery cover 20. On one side of the battery cover 20 corresponding to the battery accommodation cavity 10, there is a battery slot 203, and on the side wall of the battery slot 203, there is a battery buckle 2031. During installation, the battery 30 is placed in the battery slot 203, and the battery buckle 2031 buckles on the side of the battery facing away from the battery slot 203. The above-mentioned battery buckle 2031 has a certain elastic deformation ability. When the battery 30 is installed in the battery slot 203, the battery buckle 2031 first undergoes elastic deformation to accommodate the battery 30 in the battery slot 203, and then the battery buckle 2031 restores its elastic deformation and buckles on the side of the battery 30 facing away from the battery slot 203. The battery buckle 2031 on the side wall of the battery slot 203 can provide a firm fixing force to firmly fix the battery 30 in the battery slot 203 of the battery cover 20, prevent the battery 30 from falling off the battery cover 20, and also prevent the battery 30 from shaking or loosening during use, maintaining good contact between the battery 30 and the electronic device, and improving the performance and stability of the electronic device. Preferably, there are several battery buckles 2031 mentioned above, and several battery buckles 2031 are evenly distributed circumferentially along the side wall of the battery slot 203. The even circumferential distribution of several battery buckles 2031 along the side wall of the battery slot 203 can achieve uniform fixation of the battery 30. Each circumferential part of the battery buckle 2031 bears a part of the fixing force, enabling the battery 30 to be evenly supported in the battery slot 203, effectively preventing the battery 30 from falling off the battery cover 20, and also preventing the battery 30 from shaking or loosening during device use, improving the stability and performance of the device.

[0049] In practical applications, there are at least two batteries 30. Using two or more batteries 30 can increase the total battery capacity of the electronic device, provide a longer usage time for the electronic device, extend the battery life of the electronic device, and provide better power support. In some embodiments, the battery 30 can be used as a backup power source. When one battery 30 is depleted, the other battery 30 can continue to supply power to ensure the continuous operation of the device. In some embodiments, placing the batteries 30 in a parallel or series configuration can achieve load balancing. By connecting multiple batteries 30 together, the load is evenly distributed, reducing the overuse of a single battery 30 and extending the life of the battery 30.

[0050] See Figure 2 and Figure 5As shown, when multiple batteries 30 are configured in series with two or more batteries 30 to achieve load balancing, every two adjacent batteries 30 form a battery unit group; each battery unit group has two corresponding positive plates 103 and one negative plate 102 in the battery accommodating cavity 10; the two positive plates 103 are arranged corresponding to the positive electrodes of the batteries 30. When the batteries 30 are placed in the battery accommodating cavity 10, the positive electrode of the battery is connected to one end of the corresponding positive plate 103; the negative plate 102 is arranged between two adjacent batteries 30 in a group; one end of the negative plate 102 is respectively provided with electrode posts 1022 corresponding to the negative electrodes of the two adjacent batteries 30, and the other end has at least one surface segment 1021 for connecting the two electrode posts 1022; when the batteries 30 are placed in the battery accommodating cavity 10, the two electrode posts 1022 are connected to the negative electrodes of the corresponding batteries 30.

[0051] The other ends of the above-mentioned positive plate 103 and negative plate 102 are used to connect to the circuit board of the electronic device, so that the battery 30 powers the electronic device. The other end of the negative plate 102 has at least one surface segment 1021. The bottom of the surface segment 1021 is used to connect to the circuit board of the electronic device, and the two ends of the surface segment 1021 are connected to the two electrode posts 1022 to ensure stable current transmission and provide a more stable power supply; the surface segment 1021 can be a single plane or formed by splicing multiple planes, or can be a single arc surface or formed by splicing multiple arc surfaces; it can also be formed by splicing one or more planes and one or more arc surfaces. The negative plate 102 is arranged between two adjacent batteries 30 in a group, and the negative electrodes of the two adjacent batteries 30 are connected through the electrode posts 1022. Even if the two batteries 30 share a negative plate 102, it can reduce the connection components between the batteries, reduce the material cost, and at the same time reduce the complexity of assembly and maintenance. At the same time, reducing the wire layout can effectively reduce the overall size of the electronic device and make the electronic device more compact and portable.

[0052] See Figures 3-5 As shown, of course, a battery slot 203 is provided on one side of the battery cover 20 corresponding to the battery accommodating cavity 10, and a battery buckle 2031 is provided on the side wall of the battery slot 203. During installation, when the battery 30 is placed in the battery slot 203 and the battery buckle 2031 buckles on the side of the battery 30 facing away from the battery slot 203, if two batteries 30 share a negative plate 102, then a notch 2032 needs to be opened in the battery slot 203 corresponding to the electrode post 1022 to prevent the battery slot 203 from blocking the connection between the electrode post 1022 and the negative electrode of the battery 30. Of course, multiple electrode posts 1022 can be provided corresponding to a single battery 30 to ensure stable current transmission and provide a more reliable power supply by increasing the contact area between the electrode post 1022 and the negative electrode of the battery 30.

[0053] See Figure 1As shown, the above-mentioned battery cover 20 and the battery accommodating cavity 10 are snap-connected. Preferably, when the battery cover 20 covers the battery accommodating cavity 10, the battery cover 20 is placed inside the battery accommodating cavity 10. The battery cover 20 being placed inside the battery accommodating cavity 10 means that after installation, the height of the battery cover 20 from the bottom surface of the battery accommodating cavity 10 is less than or equal to the height of the battery accommodating cavity 10. When the battery cover 20 covers the battery accommodating cavity 10 and the battery cover 20 is placed inside the battery accommodating cavity 10, the connection part between the battery cover 20 and the battery accommodating cavity 10 is inside the battery accommodating cavity 10, preventing non-professionals or unauthorized personnel from disassembling and assembling through the connection part between the battery cover 20 and the battery accommodating cavity 10 and randomly opening the battery cover 20, avoiding their contact with the battery 30 or operation of the battery system, reducing potential risks and accident risks, and improving the safety of the battery system.

[0054] See Figure 1 As shown, the present utility model also provides an information display screen, which applies the above-mentioned battery replacement structure. By setting a hole 202 to disassemble the battery cover 20 and the battery accommodating cavity 10, it is avoided to expose the convex part on the outer surface of the battery accommodating cavity 10, preventing non-professionals or unauthorized personnel from randomly opening the battery cover 20, avoiding their contact with the battery 30 or operation of the battery system, reducing potential risks and accident risks, ensuring the stable operation of the battery system and avoiding accidental power-off, effectively protecting the safety of the battery 30; at the same time, during maintenance, there is no need for cumbersome operations. Only need to use a tool to extend through the hole 202 and hook the battery cover 20, and apply a pulling force to the battery cover 20 to disassemble it.

[0055] It should be noted that although the above-mentioned embodiments have been described in this article, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this article, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present utility model.
