[0032] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0035] Moreover, in addition to being able to represent an orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to specific circumstances.

[0036] A protection device provided by the utility model realizes all-round or multi-directional protection of the surrounding environment of the device body by setting the first opening and the second opening to face different directions and respectively equipping a first protection component and a second protection component. The protection device can make corresponding responses according to impacts or pressures from different directions, effectively reducing the risk of damage to the device or product in multiple directions. The first protection component and the second protection component are independent of each other and are connected by an elastic member, so that they can flexibly stretch or shift when subjected to external forces, thereby adapting to impact forces of different sizes and directions. This enhances the flexibility and adaptability of the protection device, enabling it to be applicable to a variety of complex installation and use environments. When an external object or force contacts the first contact surface or the second contact surface, the corresponding protection member will move towards the corresponding opening direction, and through the buffering effect of the elastic member, the direct impact on the internal structure of the device body is reduced. This buffering mechanism greatly reduces the risk of damage to the device or product due to external impacts. Since the protection device can effectively absorb and disperse external impact forces, the damage caused to the device or product by direct collision or impact is reduced, thereby extending the service life of the product. This is of great significance for improving the reliability of the product and reducing the maintenance cost. Embodiment

[0037] An embodiment of the utility model provides a protection device, as Figures 1 to 8 shown, including: a device body 10, the device body 10 includes a first opening 110 and a second opening 120, and the first opening 110 and the second opening 120 face different directions; a first protection component 20, the first protection component 20 includes a first protection member 210 and a first elastic member 220, one end of the first protection member 210 is provided with a first contact surface 2110, and the other end is connected to the first elastic member 220; a second protection component 30, the second protection component 30 includes a second protection member 310 and a second elastic member 320, one end of the second protection member 310 is provided with a second contact surface 3110, and the other end is connected to the second elastic member 320.

[0038] It can be understood that because the first opening 110 and the second opening 120 face different directions, the first protection component 20 and the second protection component 30 can be respectively arranged at the first opening 110 and the second opening 120. In this way, for the assembled protection device 1, when the first contact surface 2110 is pressed, the first protection member 210 moves towards the first opening 110; when the second contact surface 3110 is pressed, the second protection member 310 moves towards the second opening 120. The first protection component 20 and the second protection component 30 can achieve the technical effect of protection in two different directions.

[0039] It can be understood that the device main body 10 may further include a mounting surface 180, which can be used to connect to the device or product that needs to mount the mounting surface 180. The mounting surface 180 provided on the device main body 10 facilitates the connection between the protection device 1 and the device or product to be protected. Through standardized mounting interfaces or connection methods, the protection device 1 can be easily mounted on the target device, achieving rapid integration and deployment.

[0040] As Figure 6 and Figure 7 shown, more specifically, the other end of the first protection member 210 is provided with a first accommodating space 2120, one end of the first accommodating space 2120 is provided with a first stop portion 2130, and the first elastic member 220 is disposed in the first accommodating space 2120, and one end of the first elastic member 220 abuts against the first stop portion 2130.

[0041] It can be understood that the existence of the first stop portion 2130 provides a stable support point for the first elastic member 220, ensuring that the elastic member can be compressed or restored in a predetermined direction when subjected to pressure, thereby enhancing the stability and reliability of the entire first protection assembly 20. The first accommodating space 2120 provides sufficient movement space for the first elastic member 220, enabling the elastic member to fully stretch and compress when subjected to an external force, thereby absorbing more impact energy. This enhanced buffering effect helps to further reduce the risk of damage to the device or product due to external impacts. Integrating the first elastic member 220 into the first accommodating space 2120 inside the first protection member 210 and fixing it with a stop portion not only simplifies the overall structure of the protection device 1 but also facilitates subsequent maintenance and replacement work. When the elastic member wears out or fails, it can be more easily replaced, reducing the maintenance cost and time.

[0042] As Figure 2 and Figure 4As shown, more specifically, the device main body 10 further includes a slide rail 130, and the first protection component 20 further includes a connecting member 230. The first protection member 210 is slidably connected to the slide rail 130 through the connecting member 230, and the slide rail 130 is obliquely arranged with respect to the first contact surface 2110. The slide rail 130 provides a clear sliding path for the first protection member 210, ensuring that it can move along a predetermined direction when subjected to an external force. This guiding property not only improves the response speed and accuracy of the first protection component 20 but also helps reduce additional wear or impact caused by an uncertain movement direction. Since the slide rail 130 is obliquely arranged with respect to the first contact surface 2110, when an external force acts on the first contact surface 2110, this force is converted into a sliding force along the oblique slide rail 130, thereby pushing the first protection member 210 to move along the slide rail 130. This force transmission method enables the external impact to be more efficiently converted into a sliding motion, reducing the direct impact and damage to the internal structure of the device main body 10. The sliding connection structure enables the first protection member 210 to maintain close contact with the slide rail 130 during movement, thereby enhancing its stability. Even when subjected to a large external force, the first protection member 210 can slide smoothly along the slide rail 130, avoiding additional damage caused by shaking or deviation. When the first protection member 210 slides along the slide rail 130, its moving speed is jointly affected by the frictional force of the slide rail 130 and the resistance of the elastic member. This helps form a dynamic buffer area between the protection member and the device main body 10, further improving the buffering effect and reducing the risk of damage to the device or product. This structure optimizes the space utilization inside the device main body 10, enabling the first protection component 20 to maximize its protection function without affecting the normal operation of other components. At the same time, it is also convenient to compactly install multiple protection components at different positions of the device main body 10 to achieve a comprehensive protection effect.

[0043] As Figure 3As shown, more specifically, the device main body 10 further includes a stopper 140, and the stopper 140 is disposed beside the first opening 110. It can be understood that the stopper 140 is disposed on the movement trajectory of the first protection member 210. The main function of the stopper 140 is to serve as a physical limit on the movement trajectory of the first protection member 210. When the first protection member 210 is subjected to an external force and slides along the slide rail 130, once it reaches a predetermined maximum movement distance or position, the stopper 140 will prevent it from continuing to move. This limiting function ensures that the first protection member 210 will not move excessively when subjected to an impact, thereby avoiding the risk of collision or damage with other components inside the device main body 10. By restricting the movement range of the first protection member 210, the stopper 140 improves the overall safety of the protection device 1. Even in the case of a large external force or an unexpected situation, the first protection member 210 can maintain a relatively stable position under the restriction of the stopper 140, reducing the potential danger caused by excessive movement.

[0044] As Figure 1 and Figure 4 shown, more specifically, the area of the first contact surface 2110 is greater than or equal to the cross-sectional area of the device main body 10.

[0045] As Figure 3 and Figure 5 shown, the device main body 10 further includes a second stopper portion 150, the second stopper portion 150 is disposed in the second opening 120, one end of the second elastic member 320 abuts against the second protection member 310, and the other end abuts against the second stopper portion 150. The second elastic member 320 is obliquely disposed with respect to the second contact surface 3110. More specifically, the second protection member 310 includes a connecting rod 3120, the second elastic member 320 is sleeved on the connecting rod 3120, the second stopper portion 150 includes a through hole 1510, and the diameter of the through hole 1510 is greater than or equal to the diameter of the connecting rod 3120. More specifically, the connecting rod 3120 includes a limiting member 3130, and the diameter of the limiting member 3130 is greater than the diameter of the through hole 1510.

[0046] It can be understood that the second stop portion 150 is disposed within the second opening 120, and its main function is to serve as a stop point when the second elastic member 320 moves. When an external force acts on the second protection member 310 and attempts to move it, the second elastic member 320 will expand and contract accordingly, and when it reaches the maximum expansion and contraction amount, it will abut against the second stop portion 150, thereby restricting further movement of the second protection member 310. One end of the second elastic member 320 abuts against the second protection member 310, and the other end abuts against the second stop portion 150. This configuration ensures that the second elastic member 320 can effectively absorb and disperse the impact force acting on the second protection member 310. At the same time, the second elastic member 320 is obliquely arranged with the second contact surface 3110, and this oblique arrangement may help to better disperse the impact force and improve the protection effect. The second protection member 310 includes a connecting rod 3120, and the second elastic member 320 is sleeved on the connecting rod 3120. This enables the second elastic member 320 to be stably fixed on the connecting rod 3120 and expand and contract as the connecting rod 3120 moves. The connecting rod 3120, as the main load-bearing component of the second protection member 310, its strength and stability are crucial for the performance of the entire protection device 1. The second stop portion 150 includes a through hole 1510, and the diameter of the through hole 1510 is set to be greater than or equal to the diameter of the connecting rod 3120. This allows the connecting rod 3120 to freely slide within the through hole 1510, while ensuring that the connecting rod 3120 will not get stuck or excessively worn with the through hole 1510 when subjected to an external force. The tight fit between the through hole 1510 and the connecting rod 3120 also helps to maintain the stability of the second protection member 310 during movement. The connecting rod 3120 further includes a limiting member 3130, and the diameter of the limiting member 3130 is greater than the diameter of the through hole 1510. The main function of the limiting member 3130 is to limit the movement range of the connecting rod 3120 within the through hole 1510. When the connecting rod 3120 moves to the maximum position, the limiting member 3130 will contact the second stop portion 150 and prevent its further movement. This helps to prevent the connecting rod 3120 from disengaging from the through hole 1510 or damaging other components of the protection device 1 when subjected to an excessive impact force.

[0047] As Figure 7As shown, when both elastic members are obliquely arranged, the overall structure of the protection device 1 can be more streamlined. The obliquely arranged elastic members can make more effective use of the space inside the device body 10, avoiding the space waste that may be caused by traditional vertical or horizontal arrangements. This compact layout makes the entire protection device 1 more compact in volume while maintaining powerful functions, facilitating installation and integration into various devices. When the elastic members are obliquely arranged, there is a certain angle between the force direction and the impact force direction, which helps to disperse the impact force over a wider area and extend the transmission path of the impact force. Therefore, the protection device 1 can more effectively absorb and disperse the impact force, reduce the direct impact on the internal structure of the device, and improve the overall buffering and energy absorption capabilities.

[0048] When the obliquely arranged elastic members are subjected to an impact force, they can deform and release energy faster, thereby improving the response speed and sensitivity of the protection device 1. This rapid response ability enables the protection device 1 to more effectively handle emergencies and protect the device from damage. By optimizing the layout and angle design of the elastic members, the amount of material used can be reduced while ensuring the protection effect. This not only reduces production costs but also helps to achieve the goals of environmental protection and sustainable development.

[0049] The obliquely arranged elastic members can not only provide effective protection in a single direction but also resist impact forces from multiple directions to a certain extent. This multi-directional protection ability makes the protection device 1 more adaptable to complex and changeable working environments, improving the reliability and durability of the device.

[0050] With the development of technology, intelligent components such as sensors and controllers can be integrated into the protection device 1 to work in coordination with the obliquely arranged elastic members. By real-time monitoring and analyzing the data of the impact force, the intelligent system can automatically adjust the working state of the elastic members or trigger other protection mechanisms to achieve a more accurate and efficient protection effect.

[0051] According to the requirements of different application scenarios and device types, the obliquely arranged elastic members can be customized. For example, adjust parameters such as the material, hardness, and angle of the elastic members to adapt to different impact forces and working environment requirements. This adaptable design makes the protection device 1 more flexible and diverse, capable of meeting a wider range of market demands.

[0052] Such as Figure 2 and Figure 3As shown, more specifically, the device main body 10 further includes a third opening 160, and a cover plate 170 is provided on the third opening 160. Such a structure is more convenient for installing the second protection component 30. The setting of the third opening 160 provides a convenient channel for the installation of the second protection component 30. By opening the cover plate 170, technicians can easily access the part related to the second protection component 30 inside the device main body 10, so as to perform operations such as installation, debugging or maintenance. This design greatly simplifies the installation process and improves work efficiency. When the cover plate 170 is closed, it can closely cover the third opening 160, effectively preventing dust, moisture or other impurities from entering the inside of the device main body 10. This is of great significance for protecting the precision components and circuit structures inside the device main body 10, ensuring the overall performance and reliability of the protection device 1. When the second protection component 30 needs to be repaired or replaced, technicians can quickly access the relevant components by opening the cover plate 170 on the third opening 160. This reduces the maintenance difficulty and cost, and improves the maintainability of the protection device 1.

[0053] Compared with the prior art, the protection device 1 provided by the embodiment of the present utility model realizes all-round or multi-directional protection of the surrounding environment of the device main body 10 by setting the first opening 110 and the second opening 120 to face different directions and respectively equipping the first protection component 20 and the second protection component 30. The protection device 1 can make corresponding responses according to impacts or pressures in different directions, effectively reducing the risk of damage to the equipment or product in multiple directions. The first protection component 20 and the second protection component 30 are independent of each other and are connected by elastic members, so that they can flexibly stretch or deflect when subjected to external forces, thereby adapting to impact forces of different sizes and directions. This enhances the flexibility and adaptability of the protection device 1, making it applicable to a variety of complex installation and use environments. When an external object or force contacts the first contact surface 2110 or the second contact surface 3110, the corresponding protection member will move in the direction of the corresponding opening, and through the buffering effect of the elastic member, the direct impact on the internal structure of the device main body 10 is reduced. This buffering mechanism greatly reduces the risk of damage to the equipment or product due to external impacts. Since the protection device 1 can effectively absorb and disperse external impact forces, the damage to the equipment or product caused by direct collision or impact is reduced, thereby extending the service life of the product. This is of great significance for improving the reliability of the product and reducing the maintenance cost. Embodiment

[0054] Based on the same concept, the embodiment of the present utility model further provides an LED display module, including the protection device 1 in any one of the first embodiments.

[0055] The LED display module of the embodiment of the present utility model may be as Figure 8The rectangular module shown may also be a display module of other shapes; in addition to being an LED display module, it may also be a display module of other types; in addition to being able to be provided with protection devices 1 at all four corners of the module as shown in Figure 8 , it may also be provided with only one protection device 1, or other setting methods adapted to the requirements.

[0056] In the LED display module according to the embodiment of the present invention, by setting the first opening and the second opening of the protection device to face different directions and respectively equipping the first protection component and the second protection component, all-round or multi-directional protection of the surrounding environment of the device main body is achieved. The protection device can respond to impacts or pressures from different directions, effectively reducing the risk of damage to the device or product in multiple directions. The first protection component and the second protection component are independent of each other and are connected by elastic members, so that they can flexibly stretch or deflect when subjected to external forces, thereby adapting to impact forces of different magnitudes and directions. The flexibility and adaptability of the protection device are enhanced, enabling it to be applicable to a variety of complex installation and use environments. When an external object or force contacts the first contact surface or the second contact surface, the corresponding protection member will move in the direction of the corresponding opening, and through the buffering effect of the elastic member, the direct impact on the internal structure of the device main body is reduced. This buffering mechanism greatly reduces the risk of damage to the device or product due to external impacts. Since the protection device can effectively absorb and disperse external impact forces, the damage caused to the device or product due to direct collision or impact is reduced, thereby extending the service life of the product. This is of great significance for improving the reliability of the product and reducing the maintenance cost.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
