If the first, second is described, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the sequence of indicated technical features.

[0028] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installing and connecting should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0029] With reference to Figures 1 to 5 , the utility model proposes a kind of battery fixing structure, its design aims at realizing the effective fixation and protection of battery 300 by precise structure cooperation, to ensure the stable operation of battery 300 in various application scenarios, reduce the risk of battery 300 loosening.

[0030] The battery fixing structure comprises a base 100 and a cover plate 200, the base 100 serves as a support platform of the whole structure and needs to have good load-bearing capacity and stability. On the surface of the base 100, the area where the battery 300 is to be installed is provided with a plurality of support plates 110, which are not simply flat structures but are customized according to the specific shape of the target battery 300. Specifically, the support plates 110 are arranged vertically, and the upper end surface of each support plate 110 is provided with a groove that matches the shape of the battery 300. The groove is used to place the battery 300 and plays a role of positioning. The plurality of support plates 110 contact the front and rear ends or the front, middle and rear parts of the battery 300, thereby improving the support of the battery 300 and preventing the battery 300 from tilting.

[0031] The cover plate 200 is another important component of the battery fixing structure, and cooperates with the base 100 to form a closed or semi-closed space to accommodate the battery 300. The side of the cover plate 200 facing the base 100 is also provided with a containing groove that matches the shape of the battery 300. The containing groove is used to limit the battery 300 and plays a role of positioning, and limits the movement of the battery 300 in the vertical direction. Figure 4 and Figure 5 As shown in Figs. 7 and 8, the inner wall of the containing groove is not smooth but is ingeniously provided with an elastic member 210, which can be a spring sheet, an elastic rubber strip or other materials with appropriate elasticity and restoring force.

[0032] The role of the elastic member 210 is that when the cover plate 200 is fixedly connected with the base 100 by some means (such as screw fastening, buckle connection, etc.), the elastic member 210 can abut against the battery 300. The elastic member 210 is subjected to pressure and deformed, and the restoring force of the elastic member 210 directly acts on the surface of the battery 300, forming additional fixing force. The use of the elastic member 210 enhances the firmness of the battery 300 fixation and can also absorb external impact to a certain extent, preventing the battery 300 from loosening. In addition, the introduction of the elastic member 210 also allows the battery 300 to have a certain tolerance space during installation. Even if the size of the base 100 and the cover plate 200 is slightly different, the structure can still be adapted through the deformation of the elastic member 210, improving the compatibility and practicality of the structure.

[0033] The battery 300 is fixed between the above-mentioned base 100 and cover plate 200, and the grooves on the support plates 110 and the containing grooves of the cover plate 200 jointly constitute the limitation of the battery 300. Through the elastic pressure of the elastic member 210, dynamic fixation of the battery 300 is realized. During normal use, even if external factors such as vibration and impact are encountered, the battery 300 is difficult to fall off or loosen from the fixing structure, thereby greatly reducing the risk of equipment failure or safety accidents caused by loosening of the battery 300.

[0034] In addition, the material selection of the battery fixing structure is also crucial. The base 100 and the cover plate 200 are usually made of high-strength, corrosion-resistant metal materials or engineering plastics to ensure the durability and stability of the structure. The elastic member 210 is selected from materials with high elastic modulus, good wear resistance and chemical stability, such as stainless steel spring sheets or special rubbers, to maintain its elastic properties for a long time.

[0035] In summary, the technical effect of the battery fixing structure is to improve the convenience and stability of the battery 300 installation, effectively reduce the risk of battery 300 loosening, and enhance the overall reliability and safety of the equipment. It is suitable for fixing batteries 300 in various portable electronic devices, household appliances, power tools and other daily necessities.

[0036] In some embodiments of the present application, the elastic member 210 is a spring sheet, which is arranged on the inner wall of the accommodating groove and protrudes from the surface of the accommodating groove. When the battery 300 is placed in the accommodating groove, the spring sheet can contact the side surface of the battery 300 and deform due to the extrusion of the battery 300, thereby generating a pressing force on the battery 300, which helps to reduce the risk of battery 300 loosening. Moreover, when the cover plate 200 is removed, the spring sheet automatically eliminates the deformation, making it easy to remove the battery 300 without affecting the disassembly of the battery 300.

[0037] In order to realize the stable combination of the spring sheet and the inner wall of the accommodating groove, while ensuring the elastic properties of the spring sheet, the following two implementation methods can be used. One is that the cover plate 200 is an injection molded part, and the elastic member 210 and the cover plate 200 are integrally formed. The cover plate 200 is manufactured by injection molding process, and the spring sheet is part of the injection molded part and is integrally formed during the injection molding process. The integrally formed structure not only improves the bonding strength of the spring sheet and the cover plate 200, but also simplifies the manufacturing process and reduces the cost. In addition, since the spring sheet and the cover plate 200 are made of the same material, their coefficients of thermal expansion are similar, thereby reducing the deformation difference caused by temperature changes and further ensuring the stability and reliability of the battery fixing structure.

[0038] Another implementation method is that the spring sheet is a metal part, which is fixed to the cover plate 200 by bolts or buckles. The spring sheet is made of metal materials such as stainless steel or spring steel to ensure its sufficient elasticity and durability. The spring sheet is fixed to the cover plate 200 by bolts or buckles, thereby forming a stable combination with the inner wall of the accommodating groove. The design of the metal spring sheet not only provides stronger clamping force, but also allows stable elastic properties within a wider temperature range. In addition, the metal spring sheet is easy to process and customize to meet the needs of different specifications of the battery 300.

[0039] In order to ensure smooth movement and effective clamping of the spring sheet in the accommodating groove, a through hole 201 is provided on the inner wall of the accommodating groove, such as Figure 4 andFigure 5 As shown, the cross-sectional area of the through hole 201 is larger than the spring to accommodate the spring, and the through hole 201 not only provides the necessary space for the installation of the spring, but also allows the spring to deform without obstruction when subjected to the extrusion of the battery 300, providing a space for deformation. The cross-sectional area of the through hole 201 is designed to be slightly larger than the cross-sectional area of the spring to ensure that the spring does not rub or jam with the edge of the through hole 201 during deformation. The spring in the through hole 201 also helps to protect the spring from collision and interference with other components. By adjusting parameters such as the size of the accommodation groove, the shape and number of springs, and the type of connecting piece, different specifications and types of batteries 300 can be accommodated.

[0040] In some other embodiments of the present application, the elastic member 210 is composed of a spring and a pressing piece, and the inner wall of the accommodation groove is provided with a counterbore, which provides space and stable support for the installation of the spring. One end of the spring is confined in the counterbore, and the other end extends out of the accommodation groove and is fixedly connected with the pressing piece. When the battery 300 is placed in the accommodation groove, the battery 300 pushes the pressing piece to compress the spring, and the pressing piece exerts uniform and moderate pressure on the battery 300 through the elastic force of the spring, thereby effectively preventing the battery 300 from loosening or shifting under vibration or impact conditions, improving the reliability of the battery 300 fixation, and helping to reduce the probability of battery 300 loosening.

[0041] As shown in Figure 2 and Figure 3 The base 100 serves as the basis of the battery fixation structure, and a plurality of mounting columns 120 are arranged on the base 100 around the battery 300. The mounting columns 120 not only serve as positioning and supporting, but also provide necessary connection points for the installation of the cover plate 200. The side of the cover plate 200 facing the base 100 is designed with a protruding ring 220, and the inner hole of the protruding ring 220 matches the size of the mounting column 120, so that the mounting column 120 can be smoothly inserted into the inner hole of the protruding ring 220. The insertion design not only simplifies the assembly process, but also improves the stability and reliability of the structure. Subsequently, the cover plate 200 is fixedly connected with the mounting column 120 through bolts, further enhancing the overall strength of the battery fixation structure. The bolt connection method is not only easy to operate, but also has good durability and shock resistance, ensuring the stability and safety of the battery 300 during long-term use.

[0042] The second aspect of the present application provides a ceiling fan, which includes the battery fixation structure of the first aspect, and is designed with a battery 300, has the characteristics of high efficiency, convenient installation and long endurance, and is suitable for use in scenarios where power supply is not available or not convenient to access.

The housing 400 is the supporting framework of the entire ceiling fan, not only an aesthetic decorative piece, but also a protective layer for the internal components. The upper end of the housing 400 is provided with a hoisting part 410, such as a sling or a hook, which facilitates users to hang the ceiling fan on the ceiling of the room, the top of the mosquito net, or other high positions, saving space and facilitating installation. The motor assembly 500, as the power source of the ceiling fan, is connected to the lower end of the housing 400 and is used to stably drive the rotation of the plurality of fan blades 510 to generate cool airflow.

[0044] The battery 300 assembly is arranged inside the housing 400, not only saving space, but also ensuring the portability and long-lasting capacity of the ceiling fan. In particular, the battery 300 assembly adopts the battery fixing structure of the first aspect embodiment, contains all the embodiments of the battery fixing structure, has all the technical effects of the battery fixing structure, improves the stability and safety of the battery 300 during the operation of the ceiling fan, and avoids the influence of the use of the ceiling fan due to the loosening of the battery 300.

[0045] Referring to Figure 2 and Figure 3 , in order to meet the needs of users for convenient maintenance of the ceiling fan, the housing 400 is designed as an upper half housing 401 and a lower half housing 402 that can be detachably connected. This design not only facilitates users to clean or repair the ceiling fan when necessary, but also allows users to replace the battery 300 assembly or the motor assembly 500 according to actual needs, improving the flexibility and expandability of the ceiling fan. The upper half housing 401 and the lower half housing 402 are firmly connected by fasteners such as screws or buckles, ensuring the overall stability during the operation of the ceiling fan. The base 100 can be fixed to the lower half housing 402 or integrally formed with the lower half housing 402.

[0046] Inside the housing 400, an installation cavity is formed between the upper half housing 401 and the lower half housing 402, and an electronic control board 600 is arranged in the installation cavity. The electronic control board 600 is the control center of the ceiling fan, responsible for receiving user operation instructions, controlling the start, stop, and speed adjustment of the motor assembly 500, and managing the charging and discharging of the battery 300 assembly. The motor assembly 500 and the battery 300 assembly are electrically connected to the electronic control board 600 through wires, and the electronic control board 600 also has overcurrent, overvoltage, and short circuit protection functions, effectively preventing damage or safety accidents of the ceiling fan caused by circuit faults.

[0047] Referring to Figure 3In order to ensure the stability and reliability of the electric control board 600 in the installation cavity, a plurality of columns 230 are arranged at the upper end of the cover plate 200, and the electric control board 600 is fixed on the columns 230 through screws or other fasteners, so as to form a stable and reliable support structure, which not only improves the stability of the electric control board 600 during the operation of the ceiling fan, but also facilitates the user to replace or maintain the electric control board 600 when necessary.
