Among many electronic equipment, the power supply type electronic equipment represented by the battery box is widely concerned and applied because it plays a key role in providing power support for various equipment.

[0003] Especially in the photography field, the battery box can be assembled to the photography equipment to provide continuous and stable power supply for the camera, so as to ensure the smooth progress of the shooting work. In the actual shooting scene, whether it is professional video production or ordinary daily shooting, the photography equipment often needs to be moved and used in different environments, which inevitably increases the risk of accidental falling of the battery box and other electronic equipment.

[0004] The current battery box and other electronic equipment are usually equipped with a shell for coating, aiming to provide a certain degree of protection for the equipment to prevent external factors from causing damage to the internal circuit and components. However, since the size and direction of the impact force that may be encountered in actual use are uncertain, even with the protection of the shell, the battery box and other electronic equipment are still prone to breakage when impacted. Moreover, once the shell is broken, the internal structure is often damaged, which is usually irreparable, thereby seriously affecting the normal use of the electronic equipment. SUMMARY

[0005] The main purpose of the utility model is to provide an electronic equipment, aiming to solve the technical problem that the current electronic equipment is easy to be damaged by falling, and significantly improve the anti-falling performance and service life of the electronic equipment.

[0015] A spring acts on the telescopic rod, the spring providing an elastic force to the telescopic rod to reset it and cause the buffer to retract.

[0016] Optionally, one end of the telescopic rod opposite to its free end extends out of the housing and is provided with a limiting part extending radially.

[0039] This utility model embodiment proposes an electronic device 100 with an active buffer response mechanism. It dynamically adjusts the physical state of the buffer structure at the moment of a drop to achieve buffer protection during a fall. Specifically, it is an electronic device protection solution capable of sensing the drop state in real time and actively releasing buffer energy. This electronic device can be a battery-powered device such as a battery case for photographic equipment.

[0040] Reference Figures 1 to 3 The electronic device 100 includes:

[0041] The main body 110 includes a controller 111 and a power supply battery 112 electrically connected to the controller 111. The main body 110 serves as the core structure of the electronic device, internally housing components such as the controller 111 and the power supply battery 112. The main body 110 can be in the shape of a cube, cuboid, cylinder, etc., and this embodiment does not impose any limitation on this. The controller 111, as the core control unit of the device, is responsible for coordinating the operation and response of various components. The power supply battery 112 can be a battery originally configured in the electronic device (i.e., a built-in battery), used to power various electrical components of the electronic device (such as the electromagnetic buffer device 120).

[0042] An electromagnetic buffer device 120 is located on the main body 110 and electrically connected to the controller 111. The electromagnetic buffer device 120 is connected to a buffer element 10 and can drive the buffer element 10 to extend or retract. The electromagnetic buffer device 120 mainly consists of an electromagnetic drive component (such as an electromagnetic coil, metal rod, etc.), which precisely drives the buffer element 10 by controlling the magnitude and direction of the electromagnetic force. The buffer element 10 can be made of specially designed elastic materials, such as high-strength rubber or shape memory alloy composite materials, to ensure effective absorption and dispersion of energy when subjected to drop impacts, while also possessing good wear resistance and fatigue resistance to guarantee long-term reliability.

[0043] Sensor 130, located on the body 110 and electrically connected to the controller 111, is used to sense whether the body 110 is falling. Sensor 130 can be a combination of various sensors such as an accelerometer and a gyroscope, capable of accurately detecting changes in the motion state of the body 110 in three-dimensional space. By real-time monitoring and analysis of parameters such as acceleration and angular velocity, it accurately determines whether the body 110 is in a falling state.

[0044] The controller 111 is configured to energize the electromagnetic buffer device 120 when the sensor 130 detects a fall of the body 110, causing the electromagnetic buffer device 120 to extend the buffer member 10; and to de-energize the electromagnetic buffer device 120 when the sensor 130 does not detect a fall of the body 110, causing the electromagnetic buffer device 120 to retract the buffer member 10. Specifically, the controller 111 is pre-configured with specific control logic. When the sensor 130 detects a fall of the body 110, the controller 111 quickly energizes the electromagnetic buffer device 120. The energized electromagnetic buffer device 120 generates electromagnetic force, causing the buffer member 10 to quickly extend from the surface of the body 110, forming effective buffer protection before the equipment contacts the ground or other impact objects. When the sensor 130 does not detect a drop on the main body 110, the controller 111 controls the electromagnetic buffer device 120 to be de-energized. This effectively reduces power consumption, improving battery life and usage time. Furthermore, the buffer 10 remains retracted into the main body 110, preventing any additional bulk and maintaining the device's compactness and convenience. The controller 111 can utilize a fast and stable microcontroller 111, with pre-programmed drop detection algorithms and control logic to ensure a rapid response (e.g., within milliseconds) after detecting a drop signal, controlling the electromagnetic buffer device 120 to extend the buffer 10 promptly. The electromagnetic buffer device 120 uses a high-performance electromagnetic coil 123 and low-resistance wires to reduce energy consumption and improve electromagnetic response speed. Simultaneously, the structure of the electromagnetic drive section is optimized with a compact design layout, improving the performance of the electromagnetic buffer device 120 without increasing the device's size.

[0045] The working principle of this electronic device is as follows:

[0046] Drop detection process: Sensor 130 continuously monitors the motion parameters of the device 110 in three-dimensional space, such as acceleration and angular velocity, at a high frequency (e.g., thousands of times per second). When the device is dropped, its acceleration and angular velocity change drastically. Sensor 130 captures these changes and transmits them to controller 111. Controller 111 analyzes and processes the signals from the sensors using a pre-programmed drop detection algorithm. For example, if the device's acceleration in a certain direction exceeds a preset drop threshold and the duration reaches a certain time (e.g., a few milliseconds), controller 111 can determine that the device is in a drop state.

[0047] Buffer Response Phase: Once the controller 111 determines that the equipment has fallen, it immediately sends a power-on command to the electromagnetic buffer device 120. Upon receiving the power-on signal, the electromagnetic coil 123 of the electromagnetic buffer device 120 rapidly generates electromagnetic force to drive the buffer element 10 connected to the electromagnetic buffer device 120 to quickly extend from the surface of the main body 110. Because the buffer element 10 is made of a special elastic material, when the equipment comes into contact with the ground or other impact objects, the buffer element 10 can absorb most of the impact energy through its own elastic deformation, thereby effectively reducing the impact force on the main body 110 of the equipment and protecting the internal circuits and components from damage.

[0048] Reset Mechanism: After the device completes a drop impact, when sensor 130 detects that the device's motion state has returned to normal, i.e., parameters such as acceleration and angular velocity have returned to normal range, controller 111 controls the electromagnetic buffer device 120 to de-energize. After power de-energization, the electromagnetic force of the electromagnetic buffer device 120 disappears, and the buffer element 10 retracts into the body 110 under the action of the reset spring 124 or its own elastic restoring force, waiting for the next drop detection.

[0049] Taking a camera battery case as an example, during actual shooting, the photographer may accidentally drop the camera and battery case while walking, climbing, or other activities. When the sensor 130 built into the battery case detects a drop signal, the controller 111 responds quickly, controlling the electromagnetic buffer device 120 to be energized within a very short time (e.g., within 5 milliseconds), causing the buffer 10 to extend. In a drop test from a height of 1.5 meters, the battery case without the protective structure of this invention had a breakage rate as high as 70%, while the battery case with the protective structure of this invention did not break, and the internal circuitry and battery were not significantly damaged, effectively ensuring the continuity of shooting.

[0050] This technical solution is not only applicable to battery cases for photographic equipment, but can also be widely used in other types of electronic devices that are prone to being dropped, such as power banks and handheld electronic devices, and has broad market application prospects.

[0051] In some embodiments, refer to Figure 4 The electromagnetic buffer device 120 includes:

[0052] The housing 121 is hollow and is connected to the body 110.

[0053] The telescopic rod 122 is movably inserted through the housing 121, with its free end extending out of the housing 121 and connected to the buffer member 10; wherein, the telescopic rod 122 can be a single rod, or it can be made of multiple rods (such as two) connected together;

[0054] An electromagnetic coil 123 is located inside the housing 121 and sleeved on the telescopic rod 122. The electromagnetic coil 123 is electrically connected to the controller 111 and is used to generate an electromagnetic force when energized to apply to the telescopic rod 122, so that the telescopic rod 122 moves to drive the buffer 10 to extend.

[0055] Spring 124 acts on telescopic rod 122, and spring 124 provides elastic force to telescopic rod 122 to reset it so as to drive buffer 10 to retract.

[0056] According to the law of electromagnetic induction, when current passes through the electromagnetic coil 123, a magnetic field is generated around it. When the electromagnetic coil 123, which is mounted on the telescopic rod 122, is energized, the generated magnetic field interacts with the telescopic rod 122, producing an electromagnetic force. The magnitude and direction of this electromagnetic force can be adjusted by controlling the magnitude and direction of the current. In this embodiment, when the controller 111 issues an energizing command, the electromagnetic force generated by the electromagnetic coil 123 acts on the telescopic rod 122, overcoming the elastic force of the spring 124, driving the telescopic rod 122 to extend outward from its initial position, thus realizing the extension action of the buffer 10.

[0057] Spring 124 possesses elastic potential energy. When telescopic rod 122 extends outward against the elastic force of spring 124 under the action of an external force (electromagnetic force), spring 124 deforms to store elastic potential energy. When the electromagnetic force disappears, spring 124 releases the stored elastic potential energy to return to its initial state, generating an inward force that acts on telescopic rod 122, causing telescopic rod 122 to retract and driving buffer 10 back to its initial position.

[0058] This embodiment utilizes a uniquely designed electromagnetic buffer device 120 structure, which leverages the synergistic effect of electromagnetic force and spring force 124 to achieve rapid extension and reliable retraction of the buffer 10, thereby improving the protective effect and the stability of the equipment.

[0059] In some embodiments, refer to Figure 4 One end of the telescopic rod 122, away from its free end, extends out of the housing 121 and is provided with a radially extending limiting part 1221. The spring 124 is located between the housing 121 and the limiting part 1221. One end of the spring 124 abuts against the housing 121, and the other end of the spring 124 abuts against the limiting part 1221.

[0060] Specifically, when the telescopic rod 122 extends outward against the elastic force of the spring 124 under the action of an external force (electromagnetic force), the limiting part 1221 on the telescopic rod 122 and the housing 121 press against the spring 124, so that the spring 124 is compressed and stores elastic potential energy. When the electromagnetic force disappears, the spring 124 releases its stored elastic potential energy, and the resulting elastic force is applied inward to the limiting part 1221 on the telescopic rod 122, causing the telescopic rod 122 to retract and drive the buffer 10 to return to its initial position.

[0061] In some embodiments, sensor 130 includes at least one of a speed sensor and an acceleration sensor. When sensor 130 uses a speed sensor, the speed sensor monitors the movement speed of body 110 in real time. Under normal use, body 110 has no speed change or the speed change is relatively stable. Once a drop occurs, the speed will increase rapidly in a short period of time. After detecting the abnormal speed change, the speed sensor transmits the signal to controller 111. When sensor 130 uses an acceleration sensor, the acceleration sensor continuously monitors the acceleration change of body 110 in three-dimensional space. When body 110 is dropped, its acceleration will change drastically, for example, the acceleration will increase rapidly in the vertical direction, and the acceleration may also fluctuate abnormally in the horizontal direction. After capturing these change signals, the acceleration sensor transmits them to controller 111.

[0062] In some embodiments, the buffer 10 is a silicone block; and / or, the buffer 10 is detachably connected to the electromagnetic buffer device 120.

[0063] The buffer 10 is made of silicone. Silicone material has good elasticity and flexibility. When the electronic device is dropped and impacted, the silicone block can effectively absorb and disperse the impact energy through its own elastic deformation, greatly reducing the impact intensity borne by the body 110. In addition, silicone material also has excellent wear resistance, and it is not prone to wear or cracking even under frequent friction and impact.

[0064] Because different types of electronic devices differ in their usage scenarios, drop risk levels, and dimensions, the requirements for the buffer 10 also vary. The buffer 10 is detachably connected to the electromagnetic buffer device 120, allowing the same electromagnetic buffer device 120 to accommodate various buffers 10 with different specifications and characteristics. Equipment manufacturers can select appropriate buffers 10 based on the characteristics of different electronic devices. For example, for electronic devices frequently used in complex outdoor environments with a high drop risk, a thicker buffer 10 with stronger cushioning performance can be used; while for electronic devices with strict requirements on dimensions and a relatively low drop risk, a smaller, thinner buffer 10 that still meets basic protection requirements can be selected. This high degree of adaptability and versatility broadens the application range of the electromagnetic buffer device 120 and reduces research and development and production costs. Furthermore, with the continuous development of materials science and manufacturing processes, new cushioning materials and designs are constantly emerging. The detachable connection method allows equipment manufacturers to easily upgrade and replace the buffer 10. When superior cushioning materials (such as new high-strength, high-elasticity silicone materials or other advanced composite materials) become available on the market, manufacturers can easily replace existing cushioning components 10 with new products to improve the protection performance of electronic devices without redesigning or modifying the main structure of the electromagnetic buffer device 120. This not only reduces the cost and time of product upgrades but also allows already sold electronic devices to achieve better protection by simply replacing the cushioning component 10, enhancing the product's market competitiveness and user satisfaction. The detachable connection between the cushioning component 10 and the electromagnetic buffer device 120 can be achieved through snap-fit ​​connections, adhesive connections, etc., depending on actual needs. For example, the cushioning component 10 may have a slot into which the power output end of the battery buffer device is inserted to form a snap-fit ​​engagement with the cushioning component 10. This is merely an example and not a limitation.

[0065] In some embodiments, refer to Figure 3 Electronic devices also include:

[0066] A backup battery 140 is located on the main body 110 and is electrically connected to the controller 111.

[0067] The backup battery 140 can be used to power the electromagnetic buffer device 120. Specifically, if the main body 110 is dropped and the power supply battery 112 is depleted or malfunctions, the controller 111 will activate the backup battery 140 to power the electromagnetic buffer device. In other words, the backup battery 140 acts as a "power backup" for the device. When the power supply battery 112 is depleted or malfunctions, the controller 111 can quickly switch to the backup battery 140 to ensure the electromagnetic buffer device 120 can operate normally.

[0068] In some embodiments, refer to Figure 1 and Figure 2 The main body 110 is a polyhedron with multiple vertices, and multiple electromagnetic buffer devices 120 are provided, with each electromagnetic buffer device 120 located at one vertex of the main body 110.

[0069] A polyhedron is a geometric solid enclosed by several planar polygons, such as a cube or a cuboid. The polygons that enclose the polyhedron are called its faces, the common edge of two faces is called its edge, and the common vertex of several edges is called its vertex. For example, when solid 110 is a cube or cuboid, it has eight vertices.

[0070] The vertices of the polyhedron are distributed at various critical locations on the device. When the electronic device is accidentally dropped, regardless of the angle at which it lands, it is highly likely that one of the vertices will hit the ground first. Multiple electromagnetic buffer devices 120 are respectively installed at the vertices, enabling them to respond to the impact of the drop immediately. For example, in a simulated drop test, the device lands at a side vertex. The electromagnetic buffer device 120 at that vertex quickly extends the buffer 10, effectively absorbing most of the impact force. At the same time, the electromagnetic buffer devices 120 at other vertices can also provide timely additional buffering based on the subsequent movement trend of the device, ensuring that the impact received by the device during the entire drop process is evenly distributed and absorbed, comprehensively protecting the safety of the internal circuits and components of the device, and significantly reducing the probability of damage caused by the drop.

[0071] In some embodiments, refer to Figure 1 and Figure 2 Each vertex of the body 110 is provided with a mounting hole 1101 and an accommodating space 1102 located outside the mounting hole 1101. The electromagnetic buffer device 120 is disposed in the mounting hole 1101.

[0072] The accommodating space 1102 is adapted to the buffer 10. The buffer 10 is accommodated in the accommodating space 1102 in the retracted state and is flush with each adjacent surface of the polyhedron.

[0073] Mounting hole 1101 provides a stable and precise mounting position for the electromagnetic induction device, ensuring that its sensing accuracy is not affected by shaking or displacement during equipment operation. When the equipment falls, sensor 130 can stably and quickly detect the fall signal, thereby promptly controlling the activation of electromagnetic buffer device 120. The design of the receiving space 1102 further optimizes the working state of the buffer 10. At the moment of fall, the buffer 10 quickly extends from the receiving space 1102. Because the receiving space 1102 is adapted to the buffer 10, the buffer 10 can receive the impact in the best posture, effectively dispersing and absorbing the impact force, comprehensively protecting the safety of the internal circuits and components of the equipment, and further reducing the risk of damage caused by the fall. In the retracted state, the buffer 10 can be perfectly housed in the receiving space 1102 and is flush with each adjacent surface of the polyhedron, which makes the equipment present a simple and smooth overall appearance. Whether in daily use or during transport, the device itself has no protruding parts, which not only enhances its aesthetics but also reduces the risk of scratches and collisions that could result from uneven surfaces. For users who value product appearance, this design allows the device to maintain a good visual appeal and feel while providing strong protection, thus increasing user satisfaction.

[0074] In some embodiments, refer to Figure 3 and Figure 5 Electronic devices also include:

[0075] An attitude sensor 150 is disposed on the body 110 and is used to detect the drop attitude of the body 110;

[0076] The controller 111 is also configured to energize the electromagnetic buffer device 120 in the falling direction when the sensor 130 senses that the body 110 is falling, based on the falling posture of the body 110 detected by the attitude sensor 150.

[0077] Specifically, the attitude sensor 150 can be a three-axis gyroscope, including but not limited to this. The attitude sensor 150 can detect the drop attitude of the body 110 in real time and accurately. When the device falls, the controller 111 quickly acquires the attitude information transmitted by the attitude sensor 150, thereby accurately determining the direction of fall. For example, as Figure 5As shown, if the device falls at an angle to one side, the controller 111 can quickly identify the fall posture via the attitude sensor 150 and immediately energize the electromagnetic buffer device 120 located in the fall direction. Compared to the case without attitude detection, this precise control allows the buffer 10 to extend at the most critical position and angle, making more effective contact with the ground or impact object, greatly enhancing the cushioning effect. Furthermore, based on the fall posture detected by the attitude sensor 150, the controller 111 only energizes the electromagnetic buffer device 120 located in the fall direction, while de-energizing the electromagnetic buffer devices 120 not located in the fall direction. This strategy achieves efficient utilization of cushioning resources, avoiding unnecessary power consumption and ineffective operation of the buffer device 10.

[0078] In some embodiments, the electronic device is a battery case.

[0079] Photography scenarios are complex and diverse. Whether shooting from a bumpy off-road vehicle or hiking on steep mountain terrain, the battery box faces the risk of falling from different directions. By configuring the drop-absorbing structure described in the above embodiment on the battery box, it is possible to ensure stable protection under various sudden drop conditions, maintain normal operation, improve the adaptability of the battery box in complex shooting environments, and allow photographers to focus on their creative work without worrying about damage from drops.

All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
