Each position is provided with a corresponding positive and negative electrode connection structure, which achieves a conductive connection between the batteries. This design has the following drawbacks:

[0004] 1. The partitions between the battery installation positions increase the length of the battery box, resulting in an increase in the size of the electronic device;

[0005] 2. Each battery installation position needs to be equipped with a positive and negative connection structure, including the use of a conductive spring, which increases the number of parts and assembly steps of the battery box and increases production costs;

[0006] 3. When replacing the battery, it is necessary to apply pressure to each battery installation position, which is inconvenient and affects the user experience;

[0007] 4. After the battery is installed, the battery and the battery box are in a limited relationship between a cylinder and a curved surface or a plane. Since the diameters of the batteries vary, the batteries are prone to shaking during use, affecting the reliability of the electronic equipment.

[0008] Therefore, how to reduce production costs, reduce the volume of the battery box, and improve the convenience and applicability of battery installation while ensuring the performance and reliability of the battery box is an urgent problem to be solved in the field of multi-series dry cell battery box design.

[0028] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of the present invention, when a specific device is described as being located between a first device and a second device, an intervening device may or may not be present between the specific device and the first device or the second device. When a specific device is described as being connected to another device, the specific device may be directly connected to the other device without an intervening device, or may be directly connected to the other device but with an intervening device.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0032] Reference Figures 1 to 3 The utility model provides a multi-series dry cell battery box, comprising a battery compartment 1 and a battery cover 2. The battery compartment 1 is provided with two rows of battery mounting positions 11, and each row of battery mounting positions 11 can accommodate at least three series-connected dry cells 3;

[0033] A pinch plate 12 is provided between the two rows of battery installation positions 11. The pinch plate 12 is located between two adjacent dry batteries 3. The adjacent here refers to the left and right adjacent between the two rows of batteries, not the front and back adjacent of the batteries in the same row. The pinch plate 12 acts as a limiter. When installing the dry batteries 3, the dry batteries 3 installed first are blocked by the pinch plate 12 and will not be squeezed out when other dry batteries 3 are installed later. Therefore, only one pressure needs to be applied once to complete the installation of all dry batteries 3 in each row of battery installation positions 11, which is convenient to operate.

[0034] The bottom of the battery compartment 1 is partially hollowed out to form a hollow groove 13. The width of the hollow groove 13 is smaller than the diameter of the dry cell 3. Preferably, the width of the hollow groove 13 is 1 / 3 to 2 / 3 of the diameter of the dry cell 3. For example, the diameter of the dry cell is The width of the hollowed-out groove 13 is 7.5 mm, which can well support the dry cell;

[0035] Two limiting lines 131 are formed at the top of the hollowed groove 13 for contacting the bottom of the dry battery 3. The limiting lines 131 are tangent to the cylindrical surface of the dry battery 3, so that the dry battery 3 can be stably placed in the hollowed groove 13 after assembly, limiting the left and right shaking of the dry battery 3.

[0036] A sponge layer 21 is attached to the inside of the battery cover 2. This layer can accommodate dry cell batteries 3 of varying sizes, providing cushioning and protection for the dry cell batteries 3. The battery cover 2 abuts the tops of the dry cell batteries 3 through the sponge layer 21, which, in conjunction with the two limiting lines 131 within the hollowed-out groove 13, forms a three-line contact, further reducing the gap between the dry cell batteries 3 and the battery compartment and enhancing the limiting effect.

[0037] It should be noted that by providing a battery installation position 11 with a suitable size specification, it is compatible with AA-type batteries of various diameters on the market.

[0038] Combine Figure 2 Furthermore, two rows of battery mounting positions 11 are arranged in parallel. A positive conductive terminal 111 and a negative conductive terminal 112 are respectively provided at the head and tail ends of each row of battery mounting positions 11. Each row of battery mounting positions 11 includes N battery positions 113, where N is the number of battery cells. Each row of battery mounting positions 11 is provided with N-1 corresponding gussets 12. The battery position 113 closest to the positive conductive terminal 111 is not provided with a gusset 12. The negative and positive electrodes of the dry cell batteries 3 in adjacent battery positions 113 are in direct contact, achieving series connection.

[0039] During installation, the dry batteries 3 are placed one by one from the battery position 113 where no pinch plate 12 is provided. The placed dry batteries 3 are limited by the pinch plate 12. When the last dry battery 3 is placed, only one pressure is required to complete the installation of all dry batteries 3 in a row, which is convenient to operate.

[0040] The overlapping parts of the buckle plates 12 corresponding to the two rows of battery installation positions 11 are integrally formed, which simplifies the structure and processing technology of the battery box.

[0041] Combine Figure 1 and Figure 4 and Figure 5 As an embodiment, the length of the battery cover 2 is greater than the length of the battery compartment 1. Two first buckle structures 22 are respectively provided on both sides of the battery cover 2, and two second buckle structures 14 are respectively provided on both sides of the battery compartment 1. The first buckle structure 22 and the second buckle structure 14 slide into and buckle with each other along a sliding direction. The sliding direction is the same as the direction in which the dry batteries 3 are placed one by one in the battery position 113, thereby achieving a reliable connection between the battery cover 2 and the battery compartment 1.

[0042] Preferably, the first buckling structure 22 is located in the middle of the battery cover 2 along the sliding direction, so as to prevent the middle of the battery cover 2 from bending upward, thereby further improving the structural stability of the battery box.

[0043] In summary, compared to the prior art, the above embodiment provides a multi-cell series dry cell box. By providing two parallel rows of battery mounting positions 11 in the battery compartment 1 and providing a gusset plate 12 between the two rows of battery mounting positions 11, the separator design in the prior art is replaced, thereby reducing the length of the battery box and thus reducing the volume of the battery box.

[0044] Due to the limiting effect of the gusset plate 12, when installing the batteries 3, only one pressure needs to be applied to each row of batteries 3 to complete the installation, which makes the operation more convenient and improves the user experience.

[0045] A hollow groove 13 is provided at the bottom of the battery compartment 1, and two limiting lines 131 are formed to abut against the bottom of the battery 3. Combined with the sponge layer 21 of the top battery cover 2, a three-line contact is formed, which effectively reduces the gap between the battery 3 and the battery box, prevents the battery 3 from shaking during use, and improves reliability.

[0046] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
