Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] In existing electronic devices, the battery is usually securely placed in the internal structure of the device by means of snap connections or screw fastenings, specifically, it is fixed between the battery compartment cover and the back shell equipped with the battery compartment. Although this type of structural design is relatively economical in terms of cost, it also exposes several shortcomings in actual application. For example, in the assembly process of the production line, the battery cover is often arranged for assembly in the final packaging stage. However, when performing functional testing, since the corresponding structural design on the battery cover is coordinated with the back shell to prevent the battery from loosening or falling off after being fixed, in order to ensure that the battery can be firmly placed in the battery compartment, so as to smoothly test the overall function of the electronic device, the battery cover needs to be installed in place in advance. After the test is completed, the battery cover is removed. This process undoubtedly increases the complexity of the assembly process, which in turn restricts production efficiency.

[0003] In addition, as users' experience with the product continues to deepen, many users have reported that the use of clips or screws and other fixing methods has brought many inconveniences during the installation and removal of the battery. Specifically, the screw fastening method is not only time-consuming and labor-intensive, but also greatly increases the difficulty of battery installation and removal; and the problem with the clip connection method is that if the force is too small, the battery is difficult to remove smoothly; once the force is too large, it is very easy to damage the clip structure, which will have a negative impact on the fixing effect of the battery.

[0004] In view of the above situation, it is imperative to improve the existing technology.

[0005] The above information is presented as background information only to assist with understanding the present disclosure and no determination or admission is made as to whether any of the above may be used as prior art with respect to the present disclosure. Summary of the invention

[0029] Furthermore, in the electronic device, a waterproof structure is provided at the gap between the elastic electrical connector and the rear housing;

[0030] And / or, the elastic electrical connector is integrated with the rear housing by in-mold injection molding.

[0031] Furthermore, the electronic device further comprises a button;

After continuous research and design, and after repeated trial samples and improvements, the present invention with real practical value was finally created.

[0055] Please refer to Figure 1-3 The embodiment of the present invention provides an electronic device, including a battery 1, a rear shell 2 and a magnetic attraction component; wherein,

[0056] The surface of the rear shell 2 is provided with a receiving compartment 3 which is specially designed for accommodating the battery 1 and ensures that the battery 1 can be stably and properly placed in a designated position.

[0057] The magnetic attraction assembly is composed of three core parts: a permanent magnet 4, a magnetizing component 5, and a magnetized component 6. These components work together to achieve a tool-free rapid disassembly and assembly function of the battery 1.

[0058] Specifically, the permanent magnet 4 is cleverly placed on the side of the battery 1 that contacts the accommodating compartment 3 , and its stable magnetism provides a basis for subsequent quick-release operations.

[0059] The magnetizing component 5 and the magnetized component 6 are located together inside the accommodating chamber 3, and the magnetizing component 5 is wound around the magnetized component 6, forming a system that can dynamically adjust the magnetism.

[0060] When the magnetized component 5 is not powered on, the magnetized component 6 remains in a non-magnetized state. At this time, it can generate an attractive force with the permanent magnet 4, thereby effectively locking the battery 1 in the accommodating compartment 3, ensuring the stable installation of the battery 1.

[0061] When the magnetizing component 5 is powered on, it will magnetize the magnetized component 6, so that the polarity of the magnetized component 6 becomes the same as that of the permanent magnet 4. According to the principle of magnetism, repulsion will be generated between the same polarities, so the magnetized component 6 will repel the permanent magnet 4, thereby releasing the fixed relationship between the battery 1 and the accommodating compartment 3, and realizing the rapid release of the battery.

[0062] This embodiment introduces this innovative magnetic attraction component, and only controls the power-on state of the magnetized component 5, so that the battery 1 can be quickly fixed and released without the intervention of any mechanical locking mechanism. This design not only significantly improves the ease of use and user experience of the electronic device, but also greatly enhances the fixation reliability of the battery 1, and effectively avoids the problem of loosening and falling off of the battery 1. In addition, during the testing phase of the electronic device, this design also allows testers to directly test the overall function of the electronic device without pre-installing the battery cover, thereby simplifying the assembly process and improving production efficiency. In summary, this embodiment of the present invention has extremely high practical value and promotion potential, and is suitable for application and promotion in a wide range of fields.

[0063] Exemplarily, the magnetizing component 5 may be designed in the form of a coil, and the magnetized component 6 may be an iron sheet.

[0064] Specifically, the coil acts as a magnetized component 5, and can generate a magnetic field when energized. This magnetic field will act on the magnetized component 6, that is, the iron sheet, so that it is magnetized. As a high magnetic permeability material, the iron sheet has good responsiveness to the magnetic field, and is therefore very suitable as the magnetized component 6. When the magnetic field generated by the coil being energized acts on the iron sheet, the iron sheet will be magnetized and produce corresponding polarity, thereby interacting with the permanent magnet 4 (attracting or repelling, but this embodiment uses the effect of mutual repulsion) to achieve the release of the battery 1.

[0065] This combination of coil and iron sheet is not only simple and easy, but also relatively low in cost, and can meet the battery fixing and release requirements of most electronic devices. In addition, the size, shape and position of the coil and iron sheet can be adjusted according to the specific electronic device design to achieve the best magnetic attraction effect and battery fixing reliability.

[0066] In summary, this embodiment provides an economical, practical and efficient solution for fixing and releasing the battery of the electronic device by adopting the design of using the coil as the magnetized component 5 and the iron sheet as the magnetized component 6.

[0067] In the further optimization of this embodiment, the influence of the magnetized component 5 and the magnetized component 6 on the storage stability of the battery 1 is fully considered, and an innovative solution is proposed for this purpose. Specifically, a special groove is designed in the storage compartment 3 for accommodating the magnetized component 5 and the magnetized component 6.

[0068] This design cleverly solves the spatial interference problem that may be caused by the magnetized component 5 and the magnetized component 6, and ensures the stability of the battery 1 in the accommodating compartment 3. Through the setting of the groove, the magnetized component 5 and the magnetized component 6 are cleverly hidden and will not protrude from the surface in the accommodating compartment 3, thereby avoiding their direct contact or interference with the battery 1.

[0069] More importantly, this design also allows the surface of the battery 1 in contact with the storage compartment 3 to maintain a flat surface. The flat surface contact not only improves the stability and firmness of the battery 1 in the storage compartment 3, but also helps to optimize the heat conduction and heat dissipation between the battery and the rear housing 2. This is of great significance for improving the overall performance of electronic devices and extending the battery life.

[0070] In addition, the design of the groove also has certain flexibility and customizability. The size, shape and position of the groove can be precisely adjusted according to the specific size and shape of the magnetizing component 5 and the magnetized component 6, as well as the accommodation requirements of the battery 1. This flexible design enables the present embodiment to be applicable to batteries and electronic devices of different sizes and types, and has a wide range of application prospects and market demands.

[0071] In one implementation of this embodiment, the number of the permanent magnets 4 is one or two or more;

[0072] The number of the magnetized components 6 is the same as the number of the permanent magnets 4 , and each of the magnetized components 6 is arranged opposite to a corresponding one of the permanent magnets 4 .

[0073] It should be noted that the number of permanent magnets 4 is flexible and can be one, two or more. Such a design takes into account the differentiated requirements of different electronic devices for battery fixing strength and stability. By adjusting the number of permanent magnets 4, the suction force of the magnetic suction component can be effectively adjusted to ensure that the battery can be stably and reliably fixed in different application scenarios.

[0074] At the same time, the number of magnetized components 6 is completely consistent with that of the permanent magnets 4. That is, if the number of permanent magnets 4 is one, the number of magnetized components 6 is also one; if the number of permanent magnets 4 is two or more, the number of magnetized components 6 is also increased accordingly to ensure that each permanent magnet 4 can find a magnetized component 6 arranged opposite to it.

[0075] This one-to-one configuration not only ensures the structural symmetry of the magnetic attraction assembly, but also ensures its functional complementarity. When the magnetized component 5 is not powered on, each magnetized component 6 can generate an attractive force with the corresponding permanent magnet 4, and work together to firmly fix the battery in the storage compartment 3. When the magnetized component 5 is powered on, each magnetized component 6 can generate a repulsive force with the corresponding permanent magnet 4, thereby easily releasing the battery.

[0076] In summary, this specific implementation method in this embodiment, by flexibly configuring the number of permanent magnets 4 and magnetized components 6, not only meets the differentiated requirements of different electronic devices for battery fixing strength, but also ensures the optimization and coordination of the structure and function of the magnetic suction component.

[0077] Since the attraction between the permanent magnet 4 and the magnetized component 6 in the non-magnetized state is crucial to ensure that the battery 1 is firmly locked in the storage compartment 3, this embodiment deeply explores how to effectively enhance the magnetic force of the permanent magnet 4 to enhance the fixing effect of the battery. The following are several proposed and recommended implementation strategies:

[0078] The first, most direct and effective method is to increase the number of permanent magnets 4. Under the premise that physical conditions permit, the more permanent magnets 4 are set, the greater the total magnetic force they generate together, so that the battery can be locked more firmly in the storage compartment.

[0079] Second, when the number of permanent magnets 4 reaches two or more, the magnetic force can be further improved by optimizing their arrangement. Specifically, there are two arrangements worth considering: one is to make these permanent magnets in series on the magnetic circuit, that is, their magnetic field directions are the same and superimposed on each other, thereby enhancing the overall magnetic force output; the other is to use the Halbach array arrangement, which is a special permanent magnet arrangement method that can significantly improve the uniformity and strength of the magnetic field, thereby improving the magnetic effect.

[0080] Thirdly, the key to improving the magnetic force is to use strong magnetic materials to make the permanent magnet 4. Strong magnetic materials can generate stronger magnetic fields, thereby providing greater magnetic force under the same physical size.

[0081] It is worth noting that the above three strategies are not mutually exclusive, but can be used in combination with each other. For example, the number of permanent magnets can be increased at the same time, and they can be arranged in a Halbach array, while strong magnetic materials can be selected to make these permanent magnets. Such a comprehensive measure will maximize the magnetic force of the permanent magnets, thereby ensuring that the battery is firmly locked in the compartment.

[0082] In summary, by flexibly applying the above strategies, the magnetic force of the permanent magnet 4 can be effectively enhanced, providing a more stable and reliable fixing solution for the battery.

[0083] Similarly, since the repulsive force between the permanent magnet 4 and the magnetized component 6 in the magnetized state plays a decisive role in whether the battery 1 can be successfully released from the accommodating compartment 3, this embodiment deeply explores how to effectively enhance the magnetic force of the magnetized component 6 to ensure that the battery can be easily and reliably released. The following are several proposed and recommended implementation strategies:

[0084] The first, most direct and effective method is to increase the number of turns of the coil when the magnetized component 5 is a coil. Since the magnetized component 5 is usually composed of a coil, the more turns the coil has, the stronger the magnetic field generated when it is energized, so that the magnetized component 6 can be magnetized more effectively and its magnetic force can be enhanced. Therefore, under the premise of physical space and current limitations, as many coils as possible should be wound to enhance the magnetization effect.

[0085] Secondly, the material selection of the magnetizing component 5 is also crucial. A coil made of a material with a high current carrying capacity can withstand a larger current, thereby generating a stronger magnetic field at the same voltage. Therefore, selecting a material with a high current carrying capacity (such as a high-quality conductor such as copper or silver) to make the magnetizing component 5 is an important way to improve the magnetic force.

[0086] Third, the material of the magnetized component 6 also has a significant effect on the magnetic force. High magnetic permeability materials have excellent magnetization properties and can produce stronger magnetism under the same magnetic field. Therefore, choosing high magnetic permeability materials (such as ferrite, nickel-iron alloy, etc.) to make the magnetized component 6 can significantly improve its magnetic strength after magnetization.

[0087] It is worth noting that the above three strategies are not mutually exclusive, but can be used in combination with each other. For example, the number of turns of the coil of the magnetized component 5 can be increased at the same time, the coil can be made of a material with high current carrying capacity, and a material with high magnetic permeability can be selected to make the magnetized component 6. Such comprehensive measures will maximize the magnetic force of the magnetized component 6, thereby ensuring that the battery can be smoothly and reliably released from the accommodating compartment 3.

[0088] In summary, by flexibly applying the above strategies, the magnetic force of the magnetized component 6 can be effectively enhanced, providing a smoother and more reliable solution for the release of the battery.

[0089] Please refer to Figure 4The electronic device design in this embodiment is further optimized, especially in the electrical connection between the battery 1 and the mainboard 7. In this embodiment, in addition to the components mentioned above, the electronic device also adds a mainboard 7 and an electrical connection component to provide a more reliable and efficient battery connection method.

[0090] As the core component of the electronic device, the mainboard 7 is cleverly arranged inside the rear housing 2 to ensure its stability and safety. The electrical connection assembly is responsible for transmitting electrical signals between the battery 1 and the mainboard 7, and is composed of two parts: an elastic electrical connector 8 and an electrical contact point 9.

[0091] The electrical contact points 9 are arranged on the side of the battery 1 that contacts the storage compartment 3. They are like "switches" waiting to be activated, ready to establish a connection with the elastic electrical connector 8 at any time. The elastic electrical connector 8 is like a bridge, which is cleverly inserted into the rear shell 2. The end of the elastic electrical connector 8 located inside the rear shell 2 is electrically connected to the mainboard 7; the end of the elastic electrical connector 8 located outside the rear shell 2 is located inside the storage compartment 3, and can be elastically contacted with the electrical contact points 9 to achieve electrical connection.

[0092] This design not only solves the problems of pad pulling, PIN removal, PIN breakage and shell breakage that may occur in traditional connection methods, but also greatly improves the reliability and stability of battery connection. When the battery 1 is firmly placed in the battery compartment 3, the attraction force of the permanent magnet 4 and the magnetized component 6 will press the elastic electrical connector 8 and the electrical contact point 9 tightly together, so that a stable electrical connection is established between them.

[0093] For example, in a specific implementation, the elastic electrical connector 8 can be a high-performance connection element such as a Pogo pin, which is known for its excellent elasticity and conductivity, while the electrical contact point 9 can be a common contact form such as a PAD point, and the coordination between them is simple and efficient.

[0094] In summary, this embodiment provides a new, more reliable and efficient solution for battery connection of electronic devices by introducing the mainboard 7 and the electrical connection assembly (including the elastic electrical connector 8 and the electrical contact point 9). This design not only ensures that the battery 1 can easily establish an electrical connection with the mainboard 7 during installation, but also effectively improves the stability and durability of the connection through elastic contact.

[0095] Please refer again Figure 4In one implementation of this embodiment, the waterproof performance of the electronic device is significantly improved to meet high standard waterproof requirements, such as the commonly required IP68 waterproof level. This improvement is particularly aimed at the electrical connection area between the battery 1 and the mainboard 7, aiming to achieve an efficient and economical waterproof solution by optimizing the design and process.

[0096] Specifically, a waterproof structure 10 is cleverly provided at the tiny gap between the elastic electrical connector 8 and the rear shell 2. This design is intended to prevent moisture from penetrating from one side of the battery 1 into the interior of the rear shell 2, which may damage the mainboard 7. The waterproof structure 10 can be implemented using a variety of materials and technologies, among which waterproof glue is an ideal choice due to its good sealing and weather resistance. The application of waterproof glue can not only effectively block the intrusion of moisture, but also provide buffering and shock absorption to a certain extent, protecting the elastic electrical connector 8 from interference from the external environment.

[0097] In addition, this embodiment also explores a more innovative combination method, that is, through the in-mold injection molding technology, the elastic electrical connector 8 is tightly integrated with the rear shell 2. This technology is to put the elastic electrical connector 8 into an injection mold and inject molten plastic material into the injection mold. After the plastic is cooled and solidified, the elastic electrical connector 8 and the molded rear shell 2 form a firm and completely seamless or almost seamless combination. This integrated design not only greatly improves the waterproof performance, but also simplifies the assembly process and reduces the production cost.

[0098] It is worth noting that the above two waterproof measures do not exist in isolation, but can be flexibly combined according to actual needs. For example, in application scenarios with extremely high waterproof requirements, the waterproof structure 10 and the in-mold injection molding technology can be used at the same time to achieve double protection and ensure that the waterproof performance of the electronic device reaches the optimal state.

[0099] Compared with the prior art, the waterproof solution proposed in this embodiment has significant advantages. It avoids the cumbersome and costly problems of using a large amount of materials (such as waterproof rubber, foam glue, transfer FPC, etc.) in the traditional waterproof method, and instead adopts a more concise and efficient design and technical means. This not only reduces production costs and improves assembly efficiency, but also makes the overall structure of the electronic device more compact and beautiful. Therefore, the waterproof design of this embodiment undoubtedly provides new ideas and directions for the design and manufacture of contemporary electronic products.

[0100] In one implementation of this embodiment, the design of the electronic device is further optimized and upgraded, and a key component is added, namely, the button 11. This innovative design is intended to provide users with a more convenient and efficient operating experience, while further enhancing the flexibility and reliability of fixing and releasing the battery 1.

[0101] Specifically, the key 11, as an important interface for the user to interact with the electronic device, is carefully designed and has a stable connection with the mainboard 7 and the magnetized component 5. This connection not only ensures that the key can accurately transmit the user's operation instructions, but also enables the power-on state of the magnetized component 5 to be accurately controlled.

[0102] When the user needs to release the battery 1, he only needs to press the button 11, and the magnetized component 5 will be quickly energized and generate a strong magnetic field. This magnetic field will then act on the magnetized component 6, causing it to be quickly magnetized and have the ability to interact magnetically with the permanent magnet 4. By cleverly controlling the direction of the current, the same polarity repulsion effect between the magnetized component 6 and the permanent magnet 4 can be achieved. The generation of this effect will directly lead to the effective offset of the magnetic attraction exerted on the battery 1, thereby achieving the release of the battery fixation.

[0103] This design not only provides users with a more intuitive and convenient operation method, but also significantly improves the efficiency and accuracy of battery release. At the same time, due to the stable connection between the button 11 and the mainboard 7 and the magnetized component 5, as well as the precise control of the current direction, the entire battery fixing and releasing process is more stable and reliable. Such a design not only meets the user's demand for the convenience and efficiency of electronic equipment, but also provides a strong guarantee for the overall performance and user experience of electronic equipment.

[0104] In one implementation of this embodiment, the force of attraction between the magnetized component 6 and the permanent magnet 4 is greater than the gravity of the battery 1 + the displacement force of the elastic electrical connector 8 under pressure;

[0105] The repulsive force between the magnetized component 6 and the permanent magnet 4>the gravity of the battery 1-the displacement force of the elastic electrical connector 8 under pressure.

[0106] It should be noted that, in this embodiment, the magnetic force between the magnetized component 6 and the permanent magnet 4 is accurately calculated and regulated to ensure that the battery 1 can be stably fixed in the accommodating compartment 3 and can be easily released when needed.

[0107] Specifically, this embodiment sets two key mechanical conditions. First, when the battery 1 needs to be firmly fixed in the storage compartment 3, the magnetic force between the magnetized component 6 and the permanent magnet 4 must be greater than the sum of the gravity of the battery 1 and the displacement force generated by the elastic electrical connector 8 under pressure. This condition ensures that the battery 1 can still maintain a stable fixed state when it is disturbed by external forces (such as vibration, tilt, etc.) and will not accidentally fall off or shift.

[0108] Secondly, when the battery 1 needs to be released, the repulsive magnetic force between the magnetized component 6 and the permanent magnet 4 must be greater than the difference between the weight of the battery 1 and the displacement force generated by the elastic electrical connector 8 under pressure. This condition ensures that when the magnetized component 5 is energized and the magnetic force between the magnetized component 6 and the permanent magnet 4 changes from attraction to repulsion, the battery 1 can overcome its own gravity and cooperate with the resilience of the elastic electrical connector 8 to smoothly pop out or slide out of the accommodating compartment 3.

[0109] The setting of these two mechanical conditions not only reflects the in-depth understanding of the battery fixing and releasing mechanism, but also demonstrates the high attention to detail and precision in the design process. By accurately calculating and regulating the magnetic force, the stability and reliability of the battery 1 during the fixing and releasing process are achieved, providing users with a more convenient and efficient operating experience.
