DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the utility model, not all the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0024] A charging device is a portable charging device that can be carried by an individual. It is mainly used to provide power for consumer electronic products such as handheld mobile devices (such as mobile phones, tablet computers, digital cameras, etc.). In situations where there is no external power supply, the charging device can ensure that these devices continue to work and solve the problem of insufficient power. In order to increase the capacity, existing charging devices will increase the size of the battery cell, but this will also make the weight of the whole machine too heavy. Due to the heavy weight, the inertia of the charging device will be large. When the charging device falls to the ground, it will collide with the ground. Compared with lighter charging devices, the internal components of heavier charging devices such as battery cells, circuit boards and other structures are more susceptible to damage, and may even cause safety issues such as battery cell explosion.

[0025] Based on the above problems, an embodiment of the present application provides a charging device, which can be used to charge electronic devices and has strong structural stability.

[0026] For details, please refer to Figure 1and Figure 2 The charging device 1 provided in the embodiment of the present application may include: a housing 10 and a battery cell assembly 90, and the battery cell assembly 90 may be arranged in the housing 10. The housing 10 may be used as a carrier for accommodating internal components such as the battery cell 20 and the circuit board 30, and the housing 10 may protect the battery cell assembly 90.

[0027] In this embodiment, the housing 10 may include a first shell 110, a second shell 120 and a reinforcement frame 130. The first shell 110 may be connected to one side of the reinforcement frame 130, and the second shell 120 may be connected to the other side of the reinforcement frame 130. The first shell 110, the second shell 120 and the reinforcement frame 130 may enclose a closed installation space 160.

[0028] Since the outer shell 10 is composed of three parts: the first shell 110, the second shell 120 and the reinforcement frame 130, it is beneficial to improve the impact resistance of the outer shell 10. Specifically, when the charging device 1 falls, the force at the impact point can be shared by other parts to bear together, thereby avoiding or reducing damage to internal components such as the battery cell assembly 90 during the fall, and at the same time improving the safety performance of the charging device 1.

[0029] Furthermore, in one embodiment, the first shell 110 and / or the second shell 120 may include an inner layer 140 and an outer layer 150 that are stacked, and the multi-layer structure can further protect the components in the housing 10 .

[0030] Specifically, in one embodiment, the first shell 110 may include an inner layer 140 and an outer layer 150 that are stacked, wherein the inner layer 140 is a layer close to the installation space 160, and the outer layer 150 is a layer away from the installation space 160. That is to say, when the charging device 1 falls, the outer layer 150 is the first to contact the ground and be subjected to impact force. At the same time, after being subjected to the impact force, the outer layer 150 itself can absorb and consume part of the impact force. At this time, the impact force transmitted to the inner layer 140 will be weakened to protect the inner layer and the components in the installation space 160. That is to say, setting the first shell 110 as a multi-layer structure can improve the structural stability of the first shell 110, and further enable the multi-layer structure of the first shell 110 to better protect components such as the battery cell assembly 90 arranged in the installation space 160 when the charging device 1 falls.

[0031] Furthermore, the hardness of the outer layer 150 may be greater than the hardness of the inner layer 140 , so that the outer layer 150 is harder and can better protect the inner layer 140 and components such as the battery cell assembly 90 disposed in the installation space 160 .

[0032] In one embodiment, the inner layer 140 can be set as a plastic layer, that is, the inner layer 140 can be made of plastic material. It is understandable that in some other embodiments, the inner layer 140 can also be made of materials such as resin. The inner layer 140 is softer than the structure of the outer layer 150. When the charging device 1 falls, the battery cell assembly 90 and other components arranged in the installation space 160 will first contact or collide with the inner layer 140. The above-mentioned inner layer 140 structure can reduce the impact force between the battery cell assembly 90 and other components and the inner layer 140, thereby protecting the battery cell assembly 90 and other components.

[0033] The outer layer 150 can be set as a metal layer, that is, the outer layer 150 can be made of metal material. It should be noted that the metal material here can be a pure metal layer or an alloy layer, etc., and there is no limitation here. When the charging device 1 falls, the outer layer 150 can be the first to contact the ground. Since the outer layer 150 is harder, it can better protect the inner layer 140 and components such as the battery cell assembly 90 arranged in the installation space 160.

[0034] It should be noted that, in some other embodiments, the second shell 120 may also include an inner layer 140 and an outer layer 150 that are stacked. The specific structures of the inner layer 140 and the outer layer 150 here can refer to the above, and will not be repeated here. In some other embodiments, both the first shell 110 and the second shell 120 may include an inner layer 140 and an outer layer 150 that are stacked. The specific structures of the inner layer 140 and the outer layer 150 here can also refer to the above, and will not be repeated here.

[0035] The reinforcement frame 130 may be configured to be detachably connected to the first shell 110 and may be detachably connected to the second shell 120. Taking the case where the first shell 110 and the reinforcement frame 130 are configured to be detachably connected as an example, in one embodiment, the first shell 110 may be bonded or snapped to the reinforcement frame 130, so that a small gap may be provided between the first shell 110 and the reinforcement frame 130, so that when the first shell 110 or the reinforcement frame 130 is impacted by an external force, the gap may be squeezed to consume part of the impact force, thereby facilitating the reduction of the impact force on the battery cell assembly 90 disposed in the installation space 160, thereby better protecting the battery cell assembly 90 and other components disposed in the installation space 160. Similarly, the connection method between the second shell 110 and the reinforcement frame 130 may also refer to the above, and will not be described in detail here.

[0036] The embodiment of the present application does not limit the specific material of the reinforcement frame 130. For example, it can be made of flexible materials such as plastic and rubber. When the reinforcement frame 130 is impacted by the outside world, the reinforcement frame 130 can be deformed under the action of the impact force. When the external force is removed or transmitted to other components, the reinforcement frame 130 can restore the deformation. The above-mentioned structure of the reinforcement frame 130 is conducive to reducing the possibility of damage to the reinforcement frame 130.

[0037] It should be noted that the embodiments of the present application do not limit the specific form of the battery cell assembly 90. For example, in one embodiment, the battery cell assembly 90 may include a battery cell 20 and a circuit board 30. The battery cell 20 can be used to store electrical energy and output electrical energy to the outside. The circuit board 30 can be provided with a charging and discharging circuit, which can be electrically connected to the battery cell 20 and used to selectively control the charging or discharging of the battery cell 20.

[0038] Furthermore, in one embodiment, the inner layer 140 may be provided with a first window 141, and the battery cell 20 is at least partially embedded in the first window 141, which can improve the stability of the structure between the battery cell 20 and the inner layer 140, that is, the first window 141 can limit and fix the battery cell 20. Preferably, the size of the first window 141 can be consistent with the size of the battery cell 20, which can improve the effect of the first window 141 on limiting and fixing the battery cell 20. It should be noted that, in another embodiment, the inner layer 140 may also be provided with a groove, and the battery cell 20 is at least partially embedded in the groove, which can also improve the stability of the structure between the battery cell 20 and the inner layer 140. For details, please refer to the above description, which will not be repeated here.

[0039] Specifically, the battery cell 20 can be arranged in the installation space 160 and fixed to the reinforcement frame 130. For example, the width of the reinforcement frame 130 can be set to be the same as or slightly larger than the width of the battery cell 20. In this way, when the battery cell 20 is installed in the reinforcement frame 130, the reinforcement frame 130 can cover the entire battery cell 20. This can increase the contact area between the battery cell 20 and the reinforcement frame 130, thereby reducing the possibility of the battery cell 20 being misplaced in the reinforcement frame 130 when the charging device 1 falls.

[0040] Further, in this embodiment, the battery cell 20 may include a first battery cell 230 and a second battery cell 240, and the first battery cell 230 and the second battery cell 240 may be arranged side by side, so that the capacity of the entire charging device 1 can be increased. The first battery cell 230 may be arranged in the same structure as the second battery cell 240. Taking the first battery cell 230 as an example, the first battery cell 230 may include a first body 231 and a first packaging portion 232, and the first packaging portion 232 may wrap the first body 231 and protrude from the first body 231. It can be understood that the pins of the first battery cell 230 may be led out from the first packaging portion 232 and electrically connected to the circuit board 30. The above-mentioned structural arrangement of the first battery cell 230 can prevent the first battery cell 230 from being damaged or leaking. Similarly, the second battery cell 240 may include a second body 241 and a second packaging portion 242, and the second packaging portion 242 may wrap the second body 241 and protrude from the second body 241, and the pins of the second battery cell 240 may be led out from the second packaging portion 242. Furthermore, in one embodiment, the first body 231 and the second body 241 can be arranged side by side, and the first packaging portion 232 and the second packaging portion 242 can be arranged relative to each other, so that the wiring length between the first battery cell 230, the second battery cell 240 and the circuit board 30 can be reduced, which is conducive to making the structure between the first battery cell 230, the second battery cell 240 and the circuit board more compact. Compared with dispersing the battery cell 20 and the circuit board 30, the arrangement of the battery cell 20 and the circuit board 30 in the embodiment of the present application is conducive to reducing the volume of the charging device 1, and at the same time can improve the overall stability of the charging device 1.

[0041] The circuit board 30 can be arranged in the installation space 160 and electrically connected to the battery cell 20. A charging and discharging circuit can be arranged on the circuit board 30, and the charging and discharging circuit can be electrically connected to the battery cell 20. In this embodiment, the specific arrangement position of the circuit board 30 is not limited. Preferably, the circuit board 30 can be arranged close to the battery cell 20, so that the wiring length between the circuit board and the battery cell 20 can be reduced, and the structure between the battery cell 20 and the circuit board 30 can be made more compact.

[0042] Furthermore, the inner layer 140 may be provided with a fixing structure for fixing the circuit board 30, and the circuit board 30 may be connected to the above-mentioned fixing structure. The embodiment of the present application does not limit the above-mentioned fixing structure, for example, it may be a card slot, and the circuit board 30 may be inserted into the card slot to achieve a fixed connection. The above-mentioned fixing structure may also be a screw, and the circuit board 30 may be fixed to the inner layer 140 by the screw to achieve a fixed connection. The specific setting may be based on actual conditions and is not limited here.

[0043] In one embodiment, the circuit board 30 may be provided with a light emitting portion 310 and a lampshade 320. The light emitting portion 310 may emit light, and the light may pass through the housing 10 to serve as a prompt to the user. Specifically, the lampshade 320 may be provided on the light emitting portion 310. The lampshade 320 may be used to collect the light emitted by the light emitting portion 310 and concentrate it at the lampshade 320. This may make the light more concentrated, which is beneficial to increase the brightness and thus improve the prompting effect to the user. The inner layer 140 may be provided with a second window 142. The lampshade 320 may be at least partially embedded in the second window 142. The outer layer 150 may be provided with a light hole 151 corresponding to the second window 142. It is understandable that in this embodiment, the size of the light hole 151 may be set as small as possible. If the size of the light hole 151 is set too large, the hardness of the outer layer 150 will be reduced.

[0044] Please also see Figure 2 and Figure 3 Furthermore, in one embodiment, the charging device 1 may also include a battery protection board 40. The battery protection board 40 may be arranged in the installation space 160 and between the battery cell 20 and the circuit board 30. The battery protection board 40 may be provided with a protection circuit, and the battery cell 20 may be electrically connected to the protection circuit. It is understandable that in order to reduce the wiring length between the battery protection board 40 and the battery cell 20, the battery protection board 40 may also be arranged close to the battery cell 20. For example, in one embodiment, the battery cell 20 may have a first end 210 and a second end 220 along the length direction, and the battery protection board 40 may be arranged between the first end 210 and the housing 10. Preferably, the first packaging portion 232 and the second packaging portion 242 may be located at the first end 210, and the battery protection board 40 may be arranged on one side of the first packaging portion 232 and the second packaging portion 242.

[0045] In a more specific embodiment, the length direction of the battery protection board 40 can be perpendicular to the length direction of the battery cell 20, which can further reduce the space occupied by the battery protection board 40 and the battery cell 20 in the length direction of the battery cell 20, thereby making the structure of the battery protection board 40 and the battery cell 20 more compact.

[0046] Furthermore, in one embodiment, the charging device 1 may also include a partition 50, which may be disposed between the battery protection board 40 and the battery cell 20. It is understandable that during the production and processing of the battery protection board 40, a needle-like structure may be left on the surface of the battery protection board 40. Therefore, disposing a partition 50 between the battery protection board 40 and the battery cell 20 can prevent the battery protection board 40 from causing damage to the battery cell. The embodiment of the present application does not limit the specific structure of the partition 50. For example, in one embodiment, the partition 50 may be a soft cardboard. In another embodiment, the partition 50 may be a sponge, foam, etc., which is not limited here and can be specifically set according to actual conditions.

[0047] The embodiment of the present application does not limit the thickness of the partition 50. For example, in one embodiment, the partition 50 can be arranged flush with the first packaging portion 232. This can further make the structure in the installation space 160 in the housing 10 more compact, which is beneficial to improve the structural stability of the components in the installation space 160.

[0048] Furthermore, in one embodiment, the charging device 1 may further include a buffer 60, which may be disposed on at least a portion of the outer surface of the battery cell 20, so as to further protect the battery cell 20. The embodiment of the present application does not limit the specific structure of the buffer 60, for example, in one embodiment, the buffer 60 may be a sponge, and in another embodiment, the buffer 60 may be a soft material such as cotton, which is not limited here, and may be specifically configured according to actual conditions, which is not limited here.

[0049] It should be noted that the present embodiment does not limit the charging method of the charging device 1. Please refer to Figure 1 For example, in one embodiment, the charging device 1 may further include a wireless charging module, which may be arranged in the installation space 160 and electrically connected to the circuit board 30. For another example, in another embodiment, the charging device 1 may further include a data cable 70, one end of which may be electrically connected to the circuit board 30, and the other end of which may extend out of the housing 10. Specifically, the data cable 70 may extend out of the housing 10 from the reinforcement frame 130, so that a hole may be avoided in the first housing 110 or the second housing 120, thereby facilitating the improvement of the structural stability of the first housing 110 and the second housing 120, and the other end of the data cable 70 may be detachably connected to the outer wall of the reinforcement frame 130, so that the other end of the data cable 70 may be stored in the reinforcement frame 130 when not in use, and a ring structure similar to a handle may be formed. It is understandable that in some other embodiments, the charging device 1 may also be provided with a wireless charging module and a data cable 70 at the same time. The specific configuration method may refer to the above, and will not be described in detail here.

[0050] In addition, the charging device 1 provided in the embodiment of the present application may further include a button 80. The button 80 may be electrically connected to the circuit board 30, specifically to the charging and discharging circuit, and is used to control the on or off of the charging and discharging circuit. The button 80 may extend out of the housing 10 to facilitate user operation. Preferably, the button 80 may extend out of the housing 10 from the reinforcement frame 130, thereby avoiding opening a hole in the first shell 110 or the second shell 120, thereby facilitating improving the structural stability of the first shell 110 and the second shell 120.

[0051] The charging device 1 provided in the embodiment of the present application, by setting the outer shell 10 as a closed structure surrounded by a first shell 110, a second shell 120 and a reinforcement frame 130, and forming an installation space 160 inside the above-mentioned closed structure, and then arranging the battery cell 20 and the circuit board 30 in the installation space 160, wherein the above-mentioned first shell 110 and / or the second shell 120 is set to a multi-layer structure such as a stacked inner layer 140 and an outer layer 150, which is beneficial to improving the overall stability and impact resistance of the outer shell 10. When the charging device 1 falls, due to the strong overall stability of the outer shell 10, damage to internal components such as the battery cell 20 and the circuit board 30 during the fall can be avoided or reduced, and the safety performance of the charging device 1 is improved.
