[0001] The present invention relates to the technical field of battery fixing structures, and more specifically, to a battery fixing device. In addition, the present invention also relates to an electrical device comprising the battery fixing device. Background Art

[0002] Batteries play an important role in electrical devices. For example, a CMOS battery (Complementary Metal-Oxide-Semiconductor battery) is a small battery on the motherboard. A CMOS battery is typically a CR2032 button battery that powers the CMOS chip and real-time clock (RTC) to maintain basic computer settings (such as date, time, and hardware configuration).

[0003] In the related art, a plurality of metal springs are provided at the notches of the battery slot. By pressing the metal springs, the metal springs are clamped on the edges of the battery to fix the battery.

[0004] However, with this type of fixing method, the metal spring is easily deformed, causing the battery to become loose, which can easily lead to poor battery contact or even falling off.

[0005] Therefore, how to prevent the battery from loosening is a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0006] In view of this, an object of the present invention is to provide a battery fixing device that can prevent the battery from loosening.

[0007] Another object of the present invention is to provide an electrical device comprising the above-mentioned battery fixing device, wherein the battery is not easily loosened.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0009] A battery fixing device, comprising:

[0010] A battery slot having a notch, the notch being used for allowing the battery to enter and exit the battery slot;

[0011] A pressing sheet, wherein the first end of the pressing sheet is movably connected to the battery slot, the second end of the pressing sheet is detachably connected to the battery slot, when the second end of the pressing sheet is connected to the battery slot, the pressing sheet presses the battery in the battery slot, and when the second end of the pressing sheet is detached from the battery slot, the pressing sheet can move relative to the battery slot to allow the pressing sheet to avoid the battery from entering and exiting the battery slot, and the first end and the second end are the two ends of the pressing sheet along the first direction.

[0012] On the one hand, the first end of the pressing sheet is connected to the battery slot via a hinge.

[0013] On the other hand, the maximum flip angle of the tablet is in the range of 60° to 150°.

[0014] On the other hand, when the second end of the pressing sheet is connected to the battery slot, along the first direction, the pressing sheet completely covers the slot, along the second direction, the distance between the center line of the pressing sheet and the center line of the slot is less than or equal to a preset value, and the first direction is perpendicular to the second direction.

[0015] On the other hand, the width of the pressing sheet along the second direction is 20% to 30% of the size of the notch along the second direction.

[0016] On the other hand, the second end of the pressing sheet is provided with a buckle, the battery slot is provided with a card slot, and the buckle is engaged with the card slot.

[0017] On the other hand, a buffer portion is provided on one side of the pressing sheet facing the interior of the battery container.

[0018] On the other hand, the buffer portion completely covers the side of the pressing sheet facing the battery slot, and the buffer portion is provided with an anti-slip structure.

[0019] On the other hand, the buffer portion is a phase change elastomer composite material formed by an elastic matrix and a phase change heat storage material, or the buffer portion includes:

[0020] an elastic base connected to the pressing sheet;

[0021] The phase-change heat storage material is arranged on a side of the elastic matrix away from the pressing sheet.

[0022] An electrical device comprises any one of the above-mentioned battery fixing devices.

[0023] The battery fixing device provided by the present invention has the following beneficial effects:

[0024] By movably connecting one end of the pressing sheet with the battery slot along the first direction, the pressing sheet can be moved relative to the battery slot, so that the pressing sheet can make way for the slot, or the pressing sheet can block at least part of the slot so that the second end of the pressing sheet can be connected to the battery slot; when the pressing sheet makes way for the slot, the battery can freely enter and exit the battery slot from the slot; when the pressing sheet blocks at least part of the slot and the second end of the pressing sheet can be connected to the battery slot, the pressing sheet can be fixed to the battery slot by connecting the second end of the pressing sheet to the battery slot, so that the pressing sheet maintains a position state of blocking at least part of the slot, so that the pressing sheet presses at least part of the end face of one end of the battery. Since the two ends of the pressing sheet are respectively connected to the battery slot at this time, that is, the pressing sheet crosses the slot when the second end is connected to the battery slot, the reliability of the pressing sheet position can be ensured, the battery can be directly restricted from falling out, and it is beneficial for the pressing sheet to resist vibrations in multiple directions, thereby preventing the battery from loosening, avoiding problems such as poor battery contact or falling off, and reducing the risk of data loss due to battery loosening. In addition, when the second end of the pressing plate is disassembled from the battery slot, that is, the constraint of the battery slot on the second end of the pressing plate is released, at this time, the pressing plate is only movably connected to the battery slot through the first end. Since the embodiment of the present invention adopts a movable connection method to achieve the connection between the first end of the pressing plate and the battery slot, the pressing plate can be moved to make way for the notch to facilitate the battery to enter and exit the battery slot, avoid the pressing plate from scratching the battery during the process of disassembling and assembling the battery, and avoid the pressing plate being forced to deform by external force to allow the battery to enter and exit the battery slot during the disassembly and assembly process, thereby reducing the wear of the battery and the deformation of the pressing plate, etc., improving the service life of the battery fixing device, reducing the maintenance cost for the customer, and facilitating the quick replacement of the battery. In addition, when the second end of the pressing plate is connected to the battery slot, and the pressing plate is a part of the notch that blocks the battery slot, the pressing plate presses a part of the end face of the battery corresponding to the pressing plate, so that the rest of the end face of the battery corresponding to the pressing plate is exposed, which is conducive to heat dissipation and reduces the temperature of the battery surface.

[0025] The electrical equipment provided by the present invention includes the above-mentioned battery fixing device, and the electrical equipment at least includes the beneficial effects of the above-mentioned battery fixing device. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The core of the present invention is to provide a battery fixing device that can prevent the battery from loosening. Another core of the present invention is to provide an electrical device including the battery fixing device, wherein the battery is not easy to loosen.

[0035] It should be noted that, in the embodiment of the present invention, the first direction refers to the Figure 1 The X-axis direction in the second direction refers to the Figure 1 The Y-axis direction in .

[0036] Please refer to Figure 1 、 Figure 2 and Figure 3 An embodiment of the present invention provides a battery fixing device, including a battery slot 1 and a pressing piece 2. The battery slot 1 has a notch 11, which is used for allowing the battery to enter and exit the battery slot 1; a first end of the pressing piece 2 is movably connected to the battery slot 1, and a second end of the pressing piece 2 is detachably connected to the battery slot 1. When the second end of the pressing piece 2 is connected to the battery slot 1, the pressing piece 2 presses the battery in the battery slot 1. When the second end of the pressing piece 2 is detached from the battery slot 1, the pressing piece 2 can move relative to the battery slot 1 to allow the pressing piece 2 to avoid the battery from entering and exiting the battery slot 1. The first end and the second end are the two ends of the pressing piece 2 along the first direction.

[0037] That is to say, in this embodiment, one end of the pressing piece 2 along the first direction is movably connected to the battery slot 1, so that the pressing piece 2 can move relative to the battery slot 1, thereby making the pressing piece 2 leave the notch 11, or making the pressing piece 2 cover at least part of the notch 11, so that the second end of the pressing piece 2 can be connected to the battery slot 1; when the pressing piece 2 leaves the notch 11, the battery can freely enter and exit the battery slot 1 from the notch 11; when the pressing piece 2 covers at least part of the notch 11 and the second end of the pressing piece 2 can be connected to the battery slot 1, the pressing piece 2 can be connected to the battery slot 1 by making the second end of the pressing piece 2 The sheet 2 is fixed to the battery slot 1, so that the pressing sheet 2 maintains a position state of covering at least part of the notch 11, so that the pressing sheet 2 presses at least part of the end face of one end of the battery. Since the two ends of the pressing sheet 2 are respectively connected to the battery slot 1 at this time, that is, the pressing sheet 2 crosses the notch 11 when the second end is connected to the battery slot 1, the reliability of the position of the pressing sheet 2 can be ensured, and the battery can be directly restricted from falling out, which is beneficial for the pressing sheet 2 to resist multi-directional vibrations, thereby preventing the battery from loosening, avoiding problems such as poor battery contact or falling off, and reducing the risk of data loss due to battery loosening. In addition, when the second end of the pressing plate 2 is disassembled from the battery slot 1, that is, the constraint of the battery slot 1 on the second end of the pressing plate 2 is released, at this time, the pressing plate 2 is only movably connected to the battery slot 1 through the first end. Since the embodiment of the present invention adopts a movable connection method to achieve the connection between the first end of the pressing plate 2 and the battery slot 1, the pressing plate 2 can be moved to make the pressing plate 2 clear the notch 11, so as to facilitate the battery to enter and exit the battery slot 1, avoid the pressing plate 2 from scratching the battery during the process of disassembling and assembling the battery, and avoid the pressing plate 2 being forced to deform by external force during the disassembly and assembly process to allow the battery to enter and exit the battery slot 1, thereby reducing the wear of the battery and the deformation of the pressing plate 2, etc., improving the service life of the battery fixing device, reducing the maintenance cost for the customer, and facilitating the quick replacement of the battery. In addition, when the second end of the pressing plate 2 is connected to the battery slot 1, and the pressing plate 2 is a part of the notch 11 that blocks the battery slot 1, the pressing plate 2 presses a part of the end face of the battery corresponding to the pressing plate 2, so that the rest of the end face of the battery corresponding to the pressing plate 2 is exposed, which is conducive to heat dissipation and reduces the temperature of the battery surface.

[0038] It can be seen from this that compared to the related art, in which a plurality of metal springs are provided at the notch of the battery slot, and the metal springs are pressed to make the metal springs clamp the edge of the battery to achieve the fixation of the battery, the battery fixing device provided in the embodiment of the present invention can use the pressing plate 2 to cross the notch 11 of the battery slot 1, so that the two ends of the pressing plate 2 are respectively fixed to the battery slot 1, thereby preventing the battery from loosening or falling out under the obstruction of the pressing plate 2. Moreover, for the pressing plate 2 made of elastic material, when vibration or the like causes the pressing plate 2 to deform in the direction away from the battery, the pressing plate 2 can also use its own elastic force to reset and keep the pressing plate 2 pressing the battery. Moreover, compared to increasing the number of battery fixing points in the related art by simply increasing the number of metal springs, fixing the battery using the battery fixing device of the embodiment of the present invention can avoid problems such as increased battery plugging and unplugging resistance, poor heat dissipation, and easy wear of the battery caused by increasing the number of metal springs. Compared to fixing batteries through structures such as spring pins, the battery fixing device provided by the embodiment of the present invention has a simple structure, relatively low design complexity, and good seismic resistance. In the long run, the battery fixing device provided by the embodiment of the present invention consumes low manpower, time and economic costs. Therefore, the battery fixing device provided by the embodiment of the present invention can be widely used to obtain benefits, which is conducive to promoting the advancement of electrical equipment.

[0039] It is understandable that in each of the above embodiments, the battery slot 1 has a slot wall, that is, a shell for forming the battery slot, so that the shell is used to form a battery slot 1 with a preset shape. The battery slot 1 has a cavity and a slot 11. The cavity has a certain space for accommodating batteries. The slot 11 is the only channel for the battery to enter and exit the cavity. The battery enters the cavity of the battery slot 1 from the slot 11, or the battery is taken out of the cavity of the battery slot 1 from the slot 11. It should be noted that the direction in which the battery enters and exits the battery slot is preferably perpendicular to the direction of the slot 11, that is, the battery enters or is taken out of the battery slot 1 in a direction perpendicular to the slot 11. In this case, it is necessary to enable the pressing piece 2 to move to a position that completely clears the slot 11. In other application scenarios, the direction in which the battery enters and exits the battery slot 1 may also be at a certain angle to the notch 11. This angle may be non-perpendicular, so that the battery can be tilted into the battery slot 1 or taken out of the battery slot. In this case, the pressing piece 2 does not need to be moved to a position that completely clears the notch 11. The pressing piece 2 can be projected within the plane of the notch 11 so that there is a partial overlap between the pressing piece 2 and the notch 11, as long as it does not affect the normal entry and exit of the battery slot 1. In addition, the direction in which the battery is perpendicular to the notch 11 may be the length direction of the battery, or the axial direction of the battery.

[0040] In addition, the embodiment of the present invention does not specifically limit the cross-sectional shape of the battery container 1, which may be circular, square, or other geometric shapes. In addition, the embodiment of the present invention does not limit the specific material of the outer shell of the battery container 1.

[0041] It should be noted that this embodiment does not limit the specific implementation method of the movable connection between the pressing plate 2 and the battery slot 1, as long as the pressing plate 2 can be movable relative to the battery slot 1 so that the pressing plate 2 can make way for the notch 11 or cover at least part of the notch 11.

[0042] like Figure 1-Figure 3 As shown, in some embodiments, the first end of the pressing piece 2 is connected to the battery container 1 via a hinge 3. Exemplarily, the hinge 3 can be a micro hinge 3.

[0043] In other words, in this embodiment, the hinge 3 is used to achieve a movable connection between the pressing plate 2 and the battery slot 1, so that the pressing plate 2 can rotate or swing relative to the battery slot 1, thereby allowing the pressing plate 2 to clear the notch 11 or to cover at least a portion of the notch 11. This connection method is simple and easy to implement, and it also makes the overall structure relatively compact, taking up little space.

[0044] Furthermore, this embodiment does not limit the specific rotation range of the pressing plate 2 , as long as the pressing plate 2 can open the notch 11 or cover at least part of the notch 11 so that the pressing plate 2 can be connected to the battery slot 1 .

[0045] In some embodiments, the maximum flip angle of the tablet 2 is in the range of 60° to 150°.

[0046] It should be noted that, in the embodiment of the present invention, the pressing sheet 2 may give way to the slot 11. The pressing sheet 2 may completely give way to the slot 11 so that the battery can be installed vertically aligned with the slot 11; or the pressing sheet 2 may give way to the slot 11 to a certain extent, as long as it can ensure that the battery can enter and exit the battery slot 1. For example, the pressing sheet 2 may partially overlap with the slot 11 after being projected onto the surface where the slot 11 is located, as long as the partial overlap does not affect the battery from entering and exiting the battery slot 1. For example, in this case, the battery can be inserted obliquely into the battery slot 1, etc. Exemplarily, the maximum flip angle of the pressing sheet 2 may be 75°, 90°, 100°, 110° or 130°, etc. It should be noted that the range in the embodiment of the present invention includes the endpoint values, so the endpoint values ​​are no longer listed separately.

[0047] Furthermore, in some embodiments, the maximum flip angle of the pressing plate 2 is in the range of 90° to 120°. Within this range, the pressing plate 2 can completely clear the notch 11, facilitating vertical disassembly and assembly of the battery, making it easier to remove or insert the battery into the battery compartment 1, and making the operation more convenient. In addition, the maximum flip angle of the pressing plate 2 will not be too large, thereby reducing the maximum range of motion of the pressing plate 2 and reducing the space occupied by the pressing plate 2 due to clearing the notch 11. This makes the overall structure compact and the range of motion of the pressing plate 2 relatively small. For example, the maximum flip angle of the pressing plate 2 is 95°, 105°, or 115°, etc.

[0048] Of course, in other embodiments, the pressing plate 2 may also be connected to the battery slot 1 by telescoping or performing a combined motion. For example, the pressing plate 2 is connected to the battery slot 1 via a slide rail, and the pressing plate 2 can move relative to the battery slot 1 in a direction parallel to the notch 11, so that the pressing plate 2 can clear the notch 11 or at least partially cover the notch 11 by moving the pressing plate 2. Compared to a case where the pressing plate 2 is connected to the battery slot 1 via a hinge, when the pressing plate 2 is connected to the battery slot 1 via a slide rail, the pressing plate 2 occupies relatively more space in a direction parallel to the notch 11.

[0049] In addition, in order to make the pressing sheet 2 play a better effect of pressing the battery in the battery container 1, as shown in FIG. Figure 1 As shown, in some embodiments, when the second end of the pressing sheet 2 is connected to the battery slot 1, along the first direction, the pressing sheet 2 completely covers the portion between the two opposite ends of the slot 11, and along the second direction, the distance between the center line of the pressing sheet 2 and the center line of the slot 11 is less than or equal to a preset value, and the first direction is perpendicular to the second direction.

[0050] That is to say, along the first direction, the two ends of the pressing sheet 2 extend to the opposite ends of the notch 11 respectively, so that the pressing sheet 2 completely covers the notch 11 along the first direction, and the two ends of the pressing sheet 2 along the first direction are respectively one end where the pressing sheet 2 is movably connected to the battery slot 1 and one end where the pressing sheet 2 is detachably connected to the battery slot 1, so as to ensure that the two ends of the pressing sheet 2 can be connected to the battery slot 1 respectively. In this case, the pressing sheet 2 spans the end face of the battery in the first direction, so that the battery can be better compressed to prevent the battery from loosening or falling out. In addition, it can be understood that, along the second direction, the smaller the distance between the center line of the pressing sheet 2 and the center line of the notch 11, the closer the pressing sheet 2 is to the center of the notch 11 along the second direction, so that the pressing force applied by the pressing sheet 2 to the battery can be more uniform, which is more conducive to preventing the battery from loosening and falling out.

[0051] Exemplarily, the pressing sheet 2 is rectangular, and the two ends of the pressing sheet 2 along the length direction respectively extend to the opposite ends of the notch 11 of the battery container 1, so that the pressing sheet 2 completely covers the portion between the opposite ends of the notch 11 along its length direction. Along the width direction of the pressing sheet 2, the distance between the center line of the width direction of the pressing sheet 2 and the center line of the notch 11 along the width direction of the pressing sheet 2 is within a preset range, for example, the distance between the center line of the width direction of the pressing sheet 2 and the center line of the notch 11 along the width direction of the pressing sheet 2 is between 0 and a preset value. Exemplarily, the center line of the width direction of the pressing sheet 2 coincides with the center line of the notch 11 along the width direction of the pressing sheet 2, that is, the pressing sheet 2 is located at the center position of the notch 11 along the width direction of the pressing sheet 2.

[0052] In addition, the above embodiment does not specifically limit the shape of the notch 11 of the battery slot 1. The notch 11 of the battery slot 1 can be circular, square or other shapes. For example, the notch 11 of the battery slot 1 is circular, the length of the pressing plate 2 along the first direction is equal to the diameter of the notch 11, and the center line of the pressing plate 2 along the second direction passes through the center of the notch 11.

[0053] Furthermore, in order to ensure that the pressing sheet 2 has sufficient contact area with the battery so as to better press the battery while taking into account the heat dissipation of the battery, in some embodiments, the width of the pressing sheet 2 along the second direction is 20% to 30% of the size of the notch 11 along the second direction.

[0054] That is, in this embodiment, the width of the pressing plate 2 along the second direction accounts for a portion of the dimension of the notch 11 along the second direction. The remaining dimension of the notch 11 is not covered by the pressing plate 2. This helps to expose part of the battery and facilitates heat dissipation. At the same time, the size range of this embodiment ensures that the pressing plate 2 can reliably press the battery, preventing the battery from loosening or falling off. For example, the width of the pressing plate 2 along the second direction is 25% of the dimension of the notch 11 along the second direction.

[0055] For example, the shape of the pressing sheet 2 is rectangular, the shape of the notch 11 is circular, and the width of the pressing sheet 2 is 20% to 30% of the diameter of the notch 11 .

[0056] In addition, the above embodiments do not limit the specific implementation method of the detachable connection between the pressing sheet 2 and the battery slot 1, as long as the detachable connection between the pressing sheet 2 and the battery slot 1 can be achieved.

[0057] In some embodiments, a buckle is provided at the second end of the pressing piece 2 , and a slot is provided at the battery slot 1 , and the buckle and the slot are engaged with each other.

[0058] That is to say, in this embodiment, the second end of the pressing piece 2 is detachably connected to the battery slot 1 by the engagement of the buckle with the slot. This structure is simple and convenient for assembly and disassembly operations.

[0059] It should be noted that this embodiment does not limit the specific shapes of the buckle and the slot, as long as they can be interlocked to achieve the connection between the second end of the pressing piece 2 and the battery slot 1. For example, the buckle can be an L-shaped structure, and correspondingly, the slot is an L-shaped groove that is compatible with the buckle.

[0060] Of course, in other embodiments, the second end of the pressing plate 2 can also be connected to the battery slot 1 through other methods. For example, the second end of the pressing plate 2 is provided with a fixing hole, and the slot wall at the notch 11 of the battery slot 1 is provided with a threaded hole. When the fixing hole at the second end of the pressing plate 2 is aligned with the threaded hole, the second end of the pressing plate 2 can be fixed to the battery slot 1 using a screw. To remove the second end of the pressing plate 2, the screw is simply loosened and removed. This connection method is also relatively simple.

[0061] In addition, in other embodiments, the following scheme can also be adopted: a first magnet is provided at the second end of the pressing plate 2, and a second magnet is provided at the battery slot 1. The magnetic properties of the first magnet and the second magnet are opposite, and the second end of the pressing plate 2 is fixed to the battery slot 1 through the magnetic attraction between the first magnet and the second magnet. When the second end of the pressing plate 2 needs to be removed, it is necessary to use an external force to overcome the magnetic attraction between the first magnet and the second magnet, so that the second end of the pressing plate 2 is separated from the battery slot 1.

[0062] In addition, in order to prevent the pressing sheet 2 from causing wear and tear on the battery, Figure 3 As shown, in some embodiments, a buffer portion 4 is provided on one side of the pressing sheet 2 facing the interior of the battery container 1 .

[0063] That is to say, in this embodiment, a buffer portion 4 is provided on one side of the pressing sheet 2 so that the pressing sheet 2 contacts the battery through the buffer portion 4. It can be understood that the buffer portion 4 has a certain elasticity and a buffering effect, and can absorb a certain amount of vibration, impact, etc., that is, when the pressing sheet 2 contacts the battery, the longitudinal vibration (along the direction of the pressing force) between the pressing sheet 2 and the battery can be converted into a transverse buffer (perpendicular to the direction of the pressing force) through the rigid support of the pressing sheet 2 and the shape change of the buffer portion 4, which can disperse the vibration energy, reduce vibration, enhance buffering, and thus achieve an anti-seismic effect; it can reduce the wear of the battery surface caused by the pressing sheet 2, which is beneficial to extending the service life of the battery.

[0064] Furthermore, if Figure 4 As shown, in some embodiments, the buffer portion 4 completely covers the side of the pressing sheet 2 facing the battery slot 1 , and the buffer portion 4 is provided with an anti-slip structure 5 .

[0065] That is to say, in this embodiment, the buffer portion 4 is completely covered on the side of the pressing sheet 2 facing the battery slot 1 to increase the area of ​​the buffer portion 4, so that the entire pressing sheet 2 has the buffer portion 4; at the same time, the buffer portion 4 is provided with an anti-slip structure 5 to improve the reliability of the contact between the buffer portion 4 and the battery.

[0066] It should be noted that this embodiment does not limit the specific structure of the anti-slip structure 5. For example, the anti-slip structure 5 may be a tooth-shaped structure or anti-slip lines.

[0067] In addition, the above embodiment does not limit the specific structure and material of the buffer portion 4, as long as the buffer portion 4 has a certain buffering effect.

[0068] In some embodiments, the buffer portion 4 is a phase change elastomer composite material formed by an elastic matrix and a phase change heat storage material, or the buffer portion 4 includes an elastic matrix and a phase change heat storage material, the elastic matrix is ​​connected to the side of the pressing sheet 2 facing the inside of the battery container 1; the phase change heat storage material is arranged on the side of the elastic matrix away from the pressing sheet 2.

[0069] It is understood that phase-change heat storage materials can absorb or release large amounts of latent heat through physical phase changes (such as solid-liquid, solid-solid, or liquid-gas phase transitions), thereby achieving the functions of thermal energy storage and temperature regulation. In this embodiment, by disposing the phase-change heat storage material on the side of the elastic substrate facing away from the pressing plate 2, the phase-change heat storage material is brought into contact with the battery, thereby allowing the phase-change heat storage material to absorb heat from the battery and facilitate heat dissipation from the battery. Simultaneously, the elastic substrate acts as a buffer, meaning that the buffer portion 4 not only has a buffering function but also a heat dissipation function. Alternatively, the elastic substrate and phase-change heat storage material can be formed into a phase-change elastomer composite material, so that the buffer portion 4 is elastic as a whole and can absorb and dissipate heat from the battery.

[0070] It should be noted that this embodiment does not limit the specific material of the phase change heat storage material. For example, the phase change heat storage material can be a fatty acid phase change material, paraffin, or a graphene composite material.

[0071] In addition, it should be noted that the battery container 1 can be an independent structure. When the battery fixing device is applied to an electrical device, the battery container 1 can be connected to the structural components of the electrical device. In other embodiments, the bottom of the battery container 1 can be a structural component of the electrical device.

[0072] It should be noted that the embodiment of the present invention does not limit the specific material of the pressing sheet 2, as long as the pressing sheet 2 can play the role of fixing the battery. Exemplarily, the pressing sheet 2 is a metal sheet.

[0073] In addition to the above-mentioned battery fixing device, an embodiment of the present invention further provides an electrical device including the battery fixing device disclosed in the above-mentioned embodiment. For the structures of other parts of the electrical device, please refer to the relevant technology and will not be described in detail herein.

[0074] That is to say, the focus of this embodiment is that the electrical equipment adopts the battery fixing device disclosed in any one of the above embodiments, because the battery fixing device has the following beneficial effects: by making one end of the pressing sheet 2 along the first direction movably connected to the battery slot 1, the pressing sheet 2 can be moved relative to the battery slot 1, so that the pressing sheet 2 can make way for the notch 11, or the pressing sheet 2 can block at least part of the notch 11, so that the second end of the pressing sheet 2 can be connected to the battery slot 1; when the pressing sheet 2 makes way for the notch 11, the battery can freely enter and exit the battery slot 1 from the notch 11; when the pressing sheet 2 blocks at least part of the notch 11 and the second end of the pressing sheet 2 can be connected to the battery slot 1 During connection, the second end of the pressing sheet 2 can be connected to the battery slot 1 to fix the pressing sheet 2 to the battery slot 1, so that the pressing sheet 2 maintains a position state of covering at least part of the notch 11, so that the pressing sheet 2 presses at least part of the end face of one end of the battery. Since the two ends of the pressing sheet 2 are respectively connected to the battery slot 1 at this time, that is, the pressing sheet 2 crosses the notch 11 when the second end is connected to the battery slot 1, the reliability of the position of the pressing sheet 2 can be ensured, and the battery can be directly restricted from falling out, which is beneficial for the pressing sheet 2 to resist multi-directional vibrations, thereby preventing the battery from loosening, etc., avoiding problems such as poor battery contact or falling off, and reducing the risk of data loss due to battery loosening. In addition, when the second end of the pressing plate 2 is disassembled from the battery slot 1, that is, the constraint of the battery slot 1 on the second end of the pressing plate 2 is released, at this time, the pressing plate 2 is only movably connected to the battery slot 1 through the first end. Since the embodiment of the present invention adopts a movable connection method to achieve the connection between the first end of the pressing plate 2 and the battery slot 1, the pressing plate 2 can be moved to make the pressing plate 2 clear the notch 11, so as to facilitate the battery to enter and exit the battery slot 1, avoid the pressing plate 2 from scratching the battery during the process of disassembling and assembling the battery, and avoid the pressing plate 2 being forced to deform by external force during the disassembly and assembly process to allow the battery to enter and exit the battery slot 1, thereby reducing the wear of the battery and the deformation of the pressing plate 2, etc., improving the service life of the battery fixing device, reducing the maintenance cost for the customer, and facilitating the rapid replacement of the battery. In addition, when the second end of the pressing plate 2 is connected to the battery slot 1, and the pressing plate 2 is a part of the notch 11 that blocks the battery slot 1, the pressing plate 2 presses a part of the end face of the battery corresponding to the pressing plate 2, so that the rest of the end face of the battery corresponding to the pressing plate 2 is exposed, which is conducive to heat dissipation and reduces the temperature of the battery surface. Therefore, an electrical device that adopts the battery fixing device disclosed in any of the above embodiments also has at least the above beneficial effects.

[0075] In addition, this embodiment does not limit the specific type and corresponding structure of the electrical equipment. For example, the electrical equipment can be computers such as PCs and servers, or automobiles, medical equipment, or industrial equipment. That is, in addition to being applicable to computer fields such as PCs and servers, the battery fixing device can also be applied to the automotive electronics industry. For example, the battery fixing device is used to fix the battery of an on-board ECU module. In particular, when a buffer portion 4 is provided on the side of the pressing plate 2 facing the inside of the battery slot 1, the seismic design can adapt to the bumpy environment of the vehicle. In addition, for the field of medical equipment, the arrangement of the pressing plate 2 can be used for the rapid replacement of batteries inside medical devices. In addition, for the field of industrial equipment, the battery fixing device can be applied to the seismic optimization of the battery slot 1 of equipment such as programmable logic controllers.

[0076] In addition, in the embodiment of the present invention, the specific type and structure of the battery are not limited. Exemplarily, the battery is a CMOS battery, and the battery slot 1 is provided on the mainboard of the server.
