Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to an electronic device. Background Technology

[0002] In related technologies, electronic devices employ an adhesive structure that reduces adhesive force when powered on and restores adhesive force when powered off to bond the battery of the electronic device to the device housing. When the adhesive structure is powered on, the adhesive force decreases, allowing the battery to be removed from the device housing. When the adhesive structure is not powered on, the adhesive force of the adhesive structure is restored, and the battery can be stably bonded to the device housing.

[0003] However, when removing the battery, the technology requires an external power source to power the bonding structure. Since users do not carry an external power source with them at all times, there is a problem that the battery cannot be removed when the user does not have an external power source. Utility Model Content

[0004] This utility model discloses an electronic device to solve the problem in related technologies where the battery cannot be removed when the electronic device is not equipped with an external power source.

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows: This application discloses an electronic device, which includes a device housing, a battery, and an adhesive structure. The battery is bonded to the device housing via the adhesive structure. The battery has a first electrical connection portion, and the adhesive structure has a second electrical connection portion. The electronic device has a first state and a second state. When the electronic device is in the first state, the first electrical connection portion and the second electrical connection portion are electrically connected, and the battery supplies power to the adhesive structure to reduce the adhesive force of the adhesive structure; When the electronic device is in the second state, the passage between the first electrical connection and the second electrical connection is broken, and the adhesive structure restores the adhesive force.

[0006] The technical solution adopted in this utility model can achieve the following technical effects: The electronic device disclosed in this application uses an adhesive structure that reduces adhesive force when powered on and restores adhesive force when not powered on to bond the battery to the device housing. This allows the battery to be electrically connected to the adhesive structure when it needs to be removed, thereby supplying power to the adhesive structure through the battery. This reduces the adhesive force of the adhesive structure, allowing the battery to be removed from the device housing. This enables the battery to be removed from the device housing even when the user does not have an external power source. Attached Figure Description

Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0010] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0011] Please refer to Figures 1 to 9 This utility model discloses an electronic device, which includes a device housing 100, a battery 200, and an adhesive structure 300.

[0012] It should be noted that the adhesive structure 300 disclosed in this application is an electrolytic adhesive whose adhesive strength decreases after being energized (by direct current) for a period of time (e.g., 30 seconds to 1 minute), and recovers after being left to stand for a period of time (e.g., 10 minutes to 15 minutes) after the power is turned off. The structure and working mechanism of this adhesive structure 300 are prior art, and will not be described in detail in the embodiments of this application.

[0013] The battery 200 is bonded to the device housing 100 via an adhesive structure 300. The battery 200 can be bonded to the inner surface of the device housing 100 via the adhesive structure 300, or it can be bonded to other components within the device housing 100. For example, the battery 200 can be bonded to the main unit located within the device housing 100 via the adhesive structure 300. This application does not limit the specific bonding relationship of the battery 200 within the device housing 100.

[0014] The battery 200 has a first electrical connection portion 210, the adhesive structure 300 has a second electrical connection portion 380, and the electronic device has a first state and a second state.

[0015] When the electronic device is in the first state, the first electrical connection 210 and the second electrical connection 380 are electrically connected, and the battery 200 supplies power to the adhesive structure 300 to reduce the adhesive force of the adhesive structure 300. Because the adhesive force of the adhesive structure 300 decreases, the user can then remove the battery 200 from the device housing 100.

[0016] When the electronic device is in the second state, the passage between the first electrical connection 210 and the second electrical connection 380 is broken, the adhesive structure 300 restores its adhesive force, and at this time, the battery 200 is stably bonded to the device housing 100 through the adhesive structure 300.

[0017] Specifically, the first electrical connection 210 and the second electrical connection 380 can be a plug-in structure. When the electronic device is in a first state, the first electrical connection 210 and the second electrical connection 380 are plugged in, thereby achieving an electrical connection between them. When the electronic device is in a second state, the first electrical connection 210 can be separated from the second electrical connection 380. Alternatively, the first electrical connection 210 and the second electrical connection 380 can be connected by a wire 800, on which a switch 400 can be installed. When the switch 400 is closed, an electrical connection between the first electrical connection 210 and the second electrical connection 380 is achieved; when the switch 400 is open, the connection between the first electrical connection 210 and the second electrical connection 380 is broken.

[0018] The electronic device disclosed in this application uses an adhesive structure 300 that reduces adhesive force when powered on and restores adhesive force when powered off to bond the battery 200 to the device housing 100. This allows the battery 200 to be electrically connected to the adhesive structure 300 when it is necessary to remove the battery 200, thereby supplying power to the adhesive structure 300 through the battery 200. This reduces the adhesive force of the adhesive structure 300, allowing the battery 200 to be removed. This enables the battery 200 to be removed even when the user does not have an external power source.

[0019] It should be noted that after the battery is removed, the connection between the battery and the adhesive structure 300 can be broken. The adhesive force of the adhesive structure 300 will automatically recover after a period of time. When it is necessary to re-attach the battery 200 to the device housing 100, the battery 200 can be re-attached to the device housing 100 through the adhesive structure 300.

[0020] After the adhesive structure 300 is energized, the rate at which its adhesive force decreases (i.e., the rate of debonding) is positively correlated with the applied voltage; the higher the voltage applied to the adhesive structure 300, the faster its adhesive force decreases. Therefore, when an electronic device is equipped with a battery 200 with a high output voltage (e.g., 11.1V, 14.8V, etc.), the adhesive force can be rapidly reduced after the battery 200 is electrically connected to the adhesive structure 300. However, in some electronic devices, the output voltage of the battery 200 is relatively low (e.g., 3.6V, 4.5V, etc.), and the rate at which the adhesive force of the adhesive structure 300 decreases after the battery 200 is electrically connected to the adhesive structure 300 is relatively slower.

[0021] To increase the rate at which the adhesive force of the adhesive structure 300 decreases when the output voltage of the battery 200 is low, the electronic device may optionally include a first boost module 600. When the electronic device is in a first state, the first electrical connection 210 can be electrically connected to the second electrical connection 380 via the first boost module 600. The first boost module 600 can be used to increase the voltage output by the battery 200 and transmit it to the adhesive structure 300.

[0022] It should be noted that the voltage boosting function of the first boost module 600 in electronic devices is prior art, and this application embodiment will not elaborate on the first boost module 600. The first boost module 600 can be selected from existing structures, such as directly purchasing models like the XL6009 DC-DC boost power supply regulator module or the LM2596S DC-DC power supply module. This application embodiment does not impose specific restrictions on the selection of the first boost module 600.

[0023] The electronic device disclosed in this application embodiment, by setting a first boost module 600, increases the voltage output by the battery 200 to the adhesive structure 300 after being boosted by the first boost module 600, thereby increasing the speed at which the adhesive force of the adhesive structure 300 decreases, which in turn facilitates the rapid disassembly of the battery 200.

[0024] Specifically, the first boost module 600 can be housed within the device housing 100. To improve the integrated design of the electronic device, the electronic device may optionally include a circuit board 700, which is a core component of the electronic device and may house components such as a CPU, chipset, and expansion slots. The circuit board 700 can be housed within the device housing 100, and the first boost module 600 can be housed within the circuit board 700.

[0025] The electronic device disclosed in this application integrates the first boost module 600 on the circuit motherboard 700, thereby facilitating the integrated design of the electronic device.

[0026] Optionally, the circuit board 700 may also include a processing module. The processing module is independently distributed from the first boost module 600. The processing module is the core component for the operation of the electronic device and may include components such as a CPU, chipset, and expansion slots.

[0027] The circuit board 700 may have a third electrical connection portion 710 and a fourth electrical connection portion 720. The fourth electrical connection portion 720 may be electrically connected to the processing module, and the third electrical connection portion 710 may be electrically connected to the first boost module 600. When the electronic device is in the first state, the first electrical connection portion 210 may be electrically connected to the third electrical connection portion 710, and the first electrical connection portion 210 may be disconnected from the fourth electrical connection portion 720. At this time, the first electrical connection portion 210 is electrically connected to the first boost module 600 through the third electrical connection portion 710. Since the second electrical connection portion 380 is electrically connected to the first boost module 600, that is, the first electrical connection portion 210 and the second electrical connection portion 380 are connected, the path between the battery 200 and the adhesive structure 300 is made conductive, and the battery 200 supplies power to the adhesive structure 300.

[0028] When the electronic device is in the second state, the first electrical connection part 210 can be electrically connected to the fourth electrical connection part 720, and the first electrical connection part 210 is disconnected from the third electrical connection part 710. At this time, the passage between the battery 200 and the adhesive structure 300 is disconnected, and the battery 200 begins to supply power to the processing module, thereby meeting the normal operation of the electronic device.

[0029] The electronic device disclosed in this application provides a third electrical connection portion 710 and a fourth electrical connection portion 720 on the circuit board 700. In the first state, the first electrical connection portion 210 is electrically connected to the third electrical connection portion 710 and disconnected from the fourth electrical connection portion 720. In the second state, the first electrical connection portion 210 is electrically connected to the fourth electrical connection portion 720 and disconnected from the third electrical connection portion 710. This allows the battery 200 to supply power to the bonding structure 300 and the processing module with only one first electrical connection portion 210, thus simplifying the structure of the electronic device.

[0030] Specifically, the third electrical connection 710 and the fourth electrical connection 720 can be slots, and the first electrical connection 210 can be a plug. The first electrical connection 210 and the third electrical connection 710, as well as the first electrical connection 210 and the fourth electrical connection 720, are connected and separated by plugging, thereby making the cooperation between the first electrical connection 210 and the third electrical connection 710 and the fourth electrical connection 720 simpler.

[0031] Optionally, the electronic device may also include a switch 400, which can be connected between the boost module 600 and the adhesive structure 300. In the first state, the switch 400 is closed. In the second state, the switch 400 is open.

[0032] The electronic device disclosed in this application embodiment provides a switch 400 between the boost module 600 and the adhesive structure 300. When the electronic device is in a first state, the switch 400 is closed, thereby connecting the battery 200 and the adhesive structure 300. When the electronic device is in a second state, the switch 400 is open, thereby disconnecting the connection between the battery 200 and the adhesive structure 300. This prevents the battery 200 from supplying power to the adhesive structure 300 if a short circuit occurs in the main circuit board 700 when the electronic device is in the second state.

[0033] Of course, in another embodiment, the circuit board 700 may also have only one fifth electrical connection part. Both the first boost module 600 and the processing module can be electrically connected to the fifth electrical connection part. The first electrical connection part 210 can always remain connected to the fifth electrical connection part. In this case, a switch 400 is provided between the first boost module 600 and the adhesive structure 300 to control the on / off state between the first boost module 600 and the adhesive structure 300, so that when the electronic device is in the first state, the switch 400 can be in the closed state, and when the electronic device is in the second state, the switch 400 can be in the open state. Regardless of whether the electronic device is in the first state or the second state, the battery 200 can always maintain power supply to the processing module.

[0034] In another embodiment, the battery 200 may further include a battery protection board 220 and a battery cell 230. The battery protection board 220 is a circuit board that ensures the safe operation of the battery 200 and prevents abnormal situations such as overcharging, over-discharging, overcurrent, and short circuits. The battery protection board 220 can be connected to the battery cell 230, and the battery protection board 220 may have a second boost module 221. The first electrical connection part 210 can be electrically connected to the battery cell 230 through the second boost module 221. When the electronic device is in a first state, the battery cell 230 is electrically connected to the second electrical connection part 380 in sequence through the second boost module 221 and the first electrical connection part 210. The second boost module 221 can be used to increase the voltage output by the battery cell 230 and transmit it to the bonding structure 300.

[0035] The electronic device disclosed in this application, by incorporating a second boost module 221, increases the voltage output from the battery cell 230 to the adhesive structure 300 after being boosted by the second boost module 221. This improves the rate at which the adhesive force of the adhesive structure 300 decreases, thereby facilitating the rapid disassembly of the battery 200. Furthermore, integrating the second boost module 221 onto the battery protection board 220 facilitates the integrated design of the electronic device.

[0036] Optionally, the electronic device may further include a switch 400, which can be connected between the first electrical connection portion 210 and the second electrical connection portion 380. In the first state, the switch 400 is closed, connecting the battery cell 230 to the adhesive structure 300, and the battery cell 230 supplies power to the adhesive structure 300. In the second state, the switch 400 is open, disconnecting the connection between the battery cell 230 and the adhesive structure 300.

[0037] To fully utilize the structure of the electronic device and reduce the number of components, the switch 400 can optionally be a volume button. For example, when the volume button is pressed, the switch 400 is closed, connecting the battery 200 and the adhesive structure 300. After the volume button is released and automatically returns to its original position, the switch 400 is opened, disconnecting the connection between the battery 200 and the adhesive structure 300. This embodiment of the application utilizes the volume button as the switch 400, thereby reducing the number of components and optimizing the structure of the electronic device. It should be noted that the volume button can be equipped with a pressure sensor. When the user's pressing pressure is greater than or equal to a first pressure threshold, the volume button triggers the switch 400 to close; if the pressure is less than the first pressure threshold, the switch 400 will not close. Furthermore, when the pressure is less than the first pressure threshold, the pressure sensor can control the volume change of the electronic device (e.g., increase or decrease).

[0038] It should be noted that the process of the battery 200 supplying power to the adhesive structure 300 to reduce the adhesive force of the adhesive structure 300 takes a relatively long time (e.g., 30 seconds to 1 minute). Therefore, pressing the volume button normally will not cause the adhesive force of the adhesive structure 300 to decrease excessively.

[0039] Optionally, the second electrical connection portion 380 can be a strip-shaped structure, and the second electrical connection portion 380 can extend to the side of the battery 200 opposite to the adhesive structure 300 and be attached to the battery 200.

[0040] The electronic device disclosed in this application provides a second electrical connection portion 380 as a strip-shaped structure, which allows the second electrical connection portion 380 to extend to the side of the battery 200 away from the adhesive structure 300 and to be attached to the battery 200, so that the second electrical connection portion 380 can be exposed on the surface of the battery 200, thereby facilitating the electrical connection between the first electrical connection portion 210 and the second electrical connection portion 380.

[0041] It should be noted that the electrical connection between components in this application embodiment can be a direct connection between components or an indirect connection via wire 800. For example, the second electrical connection 380 can be electrically connected to the first electrical connection 210, the first boost module 600, or the second boost module 221 via wire 800. The switch 400 can be disposed on the guide for the connection between components; for example, please refer to... Figure 4 The switch 400 can be located on the wire 800 connected between the second electrical connection part 380 and the first electrical connection part 210.

[0042] The adhesive structure 300 can utilize commercially available electrically peelable double-sided tapes such as the ISR-EST series. After bonding, it can be easily peeled off in a short time by applying a direct current. This adhesive structure 300 has been used in electronic products and is considered prior art. This application mainly focuses on the application of this adhesive structure 300. Optionally, this application discloses a specific structure of the adhesive structure 300; please refer to [reference needed]. Figure 9 The bonding structure 300 may include a first acrylic adhesive layer 310, a substrate 320, a second acrylic adhesive layer 330, a conductive metal layer 340, a first electrolytic adhesive layer 350, a non-woven fabric layer 360, and a second electrolytic adhesive layer 370 stacked sequentially. The second electrical connection portion 380 is electrically connected to the conductive metal layer 340. The first acrylic adhesive layer 310 can be bonded to the battery 200, and the second electrolytic adhesive layer 370 can be bonded to a component (such as the device housing 100) that provides the bonding base for the battery 200.

[0043] It should be noted that when the battery 200 supplies power to the adhesive structure 300, the positive terminal of the battery 200 is connected to the second electrical connection portion 380, and the negative terminal of the battery 200 is connected to the component (e.g., the device housing 100) that provides the adhesive base for the battery 200. At this time, a voltage difference is formed between the conductive metal layer 340 and the adhesive base, and the free release agent accumulates at the negative terminal (i.e., accumulates on one side of the adhesive base), thereby reducing the adhesive force of the second electrolytic adhesive layer 370. The conductive metal layer 340 can be an aluminum foil layer.

[0044] It should be further noted that the first electrolytic adhesive layer 350 and the second electrolytic adhesive layer 370, which cause the adhesive strength to decrease after the energizer is applied, are existing structures and will not be described again in this embodiment.

[0045] The above embodiments of this utility model mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0046] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
