A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] The following is based on the attached Figure 1 To Attachment Fig. 9 The protection device provided by the present invention is introduced.

[0038] Specifically, refer to Figure 1 , Figure 2 As shown, the protection device includes a housing 1, in which a chamber for accommodating a wireless communication module is provided. Both ends of the housing 1 are provided with openings connected to the chamber, through which the wireless communication module can be placed in the chamber. The openings of the housing 1 are provided with sealing end plates 11 for closing the openings, and the sealing end plates 11 and the housing 1 are detachably snap-connected by plug-in matching, thereby facilitating the process of opening and closing the housing 1.

[0039] At the same time, the protection device is also provided with a shock absorbing component, a fastening component and a heat dissipation component. The shock absorbing component is arranged at the bottom of the chamber, and can reduce the impact of the vibration of the shell 1 on the wireless communication module, thereby playing a buffering and protective effect on the wireless communication module. The fastening component is arranged at the top of the chamber, and can press the wireless communication module against the shock absorbing component from top to bottom with a preset pressure, thereby cooperating with the shock absorbing component to play a fixing effect on the wireless communication module. The heat dissipation component is arranged on the side wall of the chamber, and can transfer the heat in the chamber to the outside, thereby playing a cooling effect.

[0040] The protective device can significantly improve the operational stability and safety of the wireless communication module in complex environments. The shock-absorbing components set in the protective device can effectively absorb and disperse impact energy, reduce the risk of vibration damage, and the fastening components enhance the stability of the wireless communication module, so that the shock-absorbing components can provide good buffering protection and facilitate the installation and removal of the wireless communication module. At the same time, the design of the openings at both ends of the protective device and the plug-in buckle connection setting can further facilitate the installation and removal of the wireless communication module, thereby simplifying the installation and maintenance process.

[0041] Specifically, Figure 2 , Figure 3 As shown, in this embodiment, the shock absorbing assembly mainly includes a lifting plate 3, a damper and a shock absorbing spring 2, the damper and the shock absorbing spring 2 are arranged between the lifting plate 3 and the bottom surface of the chamber, and the above-mentioned fastening assembly can press and fix the wireless communication module on the lifting plate 3 with a preset pressure, so as to effectively absorb and dissipate the impact energy from the external environment, and significantly reduce the risk of the wireless communication module being damaged by vibration. At the same time, a guide groove 4 is arranged on the side of the chamber, and the guide groove 4 is extended along the height direction of the chamber. A guide protrusion is arranged on the side of the lifting plate 3, and the guide protrusion is slidably arranged in the guide groove 4. Through the cooperation of the guide groove 4 and the guide protrusion, the moving direction of the lifting plate 3 can be limited, thereby avoiding the lifting plate 3 and the wireless communication module from moving horizontally in the protective device, and also avoiding the side direction of the wireless communication module from being hit. Optionally, the damper is arranged inside the shock absorbing spring 2, so as to constrain the compression direction of the shock absorbing spring 2.

[0042] Preferably, if Figure 3 As shown, the shock absorbing assembly also includes a rubber pad 5, which is arranged on the top surface of the lifting plate 3 and can abut against the bottom surface of the wireless communication module, thereby further improving the buffering protection effect of the wireless communication module. Further preferably, the top surface of the rubber pad 5 is also provided with irregular anti-skid patterns, which can significantly increase the friction between the rubber pad 5 and the wireless communication module, and can also avoid the phenomenon of friction reduction caused by condensed water, thereby further avoiding the lateral movement of the wireless communication module in the protection device due to vibration, and achieving a better protection effect.

[0043] Continue to refer to Figure 2As shown, in this embodiment, the fastening assembly includes an electric push rod 20 and a fastening plate 21. The electric push rod 20 is installed on the top surface of the chamber, and the fastening plate 21 is installed on the end of the electric push rod 20 away from the top surface of the chamber. Under the action of the electric push rod 20, the fastening plate 21 can abut against the top surface of the wireless communication module and apply pressure toward the lifting plate 3, thereby cooperating with the lifting plate 3 to press and fix the wireless communication module and buffer it, and prevent the wireless communication module from separating from the lifting plate 3 along the height direction of the shell 1. Of course, in some other embodiments, a push rod filled with compressed gas or an elastic push rod can also be used. As long as the pressure value within a reasonable range can be applied, it is within the scope of protection of the present invention.

[0044] Preferably, a flexible pad 22 is provided on the bottom surface of the fastening plate 21 , and the flexible pad 22 can increase the contact area and friction between the fastening plate 21 and the wireless communication module, thereby enhancing the stability and reliability of the fixation.

[0045] In this embodiment, when it is necessary to fix the wireless communication module in the chamber, first ensure that the wireless communication module has been placed in the predetermined position; then, as the electric push rod 20 extends and retracts, the fastening plate 21 also descends and gradually approaches and contacts the wireless communication module; when the fastening plate 21 is in close contact with the wireless communication module and sufficient pressure is applied, the wireless communication module is firmly fixed in the chamber; at this time, the electric push rod 20 remains in a locked state, maintaining the downward pressure of the fastening plate 21 to ensure that the wireless communication module remains fixed.

[0046] It can be understood that through the cooperation of the shock-absorbing component and the fastening component, it is possible to effectively absorb and dissipate external impact energy and significantly reduce the risk of damage to the wireless communication module, and the wireless communication module can also be stably fixed inside the chamber, and has a certain degree of adaptability, which can cope with different degrees of shock absorption needs.

[0047] Continue to refer to Figure 2 As shown, in this embodiment, the inner wall of the chamber is provided with a detection member 23 and a controller 24, and the controller 24 is electrically connected to the detection member 23 and the fastening assembly. The detection member 23 transmits the monitored data to the controller 24 in real time, and the controller 24 is responsible for receiving, processing and analyzing the data, and making corresponding decisions according to preset algorithms and rules.

[0048] By way of example, in this embodiment, the detection element 23 includes a temperature sensor, a current sensor, and a voltage sensor. The temperature sensor is responsible for real-time monitoring of the temperature in the chamber; the current sensor is used to monitor the current in the chamber or the equipment connected thereto, and can promptly detect current anomalies, such as overload, short circuit, etc., to avoid equipment damage or safety accidents; the voltage sensor is used to monitor the voltage stability in the chamber or related equipment, to ensure that the equipment works in a stable voltage environment, and to avoid equipment failure or performance degradation caused by voltage fluctuations.

[0049] When the temperature sensor detects that the temperature in the chamber exceeds the normal range, the controller 24 can automatically start or adjust the heat dissipation component to reduce the temperature. When the current or voltage sensor detects an abnormality, the controller 24 can quickly cut off the power supply or take other safety measures to prevent equipment damage or accidents.

[0050] Specifically, continue to refer to Figure 2 As shown, the heat dissipation assembly includes a heat dissipation fan 7 and a protective net 8. The side wall of the chamber is penetrated with an assembly slot 6. The heat dissipation fan 7 is arranged in the assembly slot 6 and can drive the air flow between the inside and outside of the chamber. The protective net 8 is arranged at one end of the assembly slot 6 close to the outer surface of the shell 1 to prevent foreign matter from entering the shell 1 through the assembly slot 6 to interfere with the operation of the fan or damage the safety of the wireless communication module, thereby protecting the heat dissipation fan 7 or other internal components.

[0051] Preferably, in this embodiment, two opposite side walls of the chamber are each provided with an assembly groove 6, and at least one cooling fan 7 is provided in each assembly groove 6, so that an air flow channel conducive to the heat dissipation of the wireless communication module is formed between the two assembly grooves 6, ensuring that the air circulates smoothly in the chamber, quickly taking away the heat generated by the module, and enhancing the heat dissipation efficiency.

[0052] In addition, in order to further enhance the heat dissipation effect, heat dissipation fins 9 are also provided on the side wall of the chamber. The design of the heat dissipation fins 9 greatly increases the contact area between the housing 1 and the internal air, improves the heat exchange efficiency between the housing 1 and the wireless communication module, and enables the wireless communication module to release heat to the surrounding environment through the housing 1 more quickly, ensuring the long-term stable operation and high-efficiency performance of the wireless communication module.

[0053] like Figures 4 to 9 As shown, in this embodiment, a sealing end plate 11 for closing the opening is provided at each opening, and the sealing end plate 11 and the housing 1 are detachably snap-connected by plug-in matching. A T-shaped slide groove 12 is provided on the side of the sealing end plate 11 facing the housing 1, and a T-shaped slider 10 is provided on the housing 1. The T-shaped slider 10 can be slidably inserted in the T-shaped slide groove 12, so that the sealing end plate 11 can be detachably installed on the housing 1.

[0054] More specifically, if Figure 5 As shown, a T-shaped slider 10 is provided on each of the upper and lower sides of the opening, and the T-shaped slider 10 is extended in a direction parallel to the width of the shell 1. A T-shaped slide groove 12 is provided on the upper and lower parts of the surface of one side of the sealing end plate 11 facing the shell 1, and the T-shaped slide groove 12 is extended in a direction parallel to the width of the shell 1 (this direction is also the length direction of the sealing end plate 11). The outer dimension of the T-shaped slider 10 is consistent with the inner dimension of the T-shaped slide groove 12. When the T-shaped slider 10 is placed in the T-shaped slide groove 12, the T-shaped slider 10 can move in a straight line or curve along the track of the T-shaped slide groove 12, so as to limit and fix the sealing end plate 11 and the shell 1 in the height direction and the length direction of the shell 1, and no additional fixing device or guiding mechanism is required. This design not only simplifies the mechanical structure and reduces the manufacturing cost, but also improves the reliability and service life of the equipment.

[0055] Once the wireless communication module is placed in the shell 1, the T-shaped slider 10 is inserted into the T-shaped slot 12 and slides. This operation not only realizes the stable installation of the sealing end plate 11 at the open end of the shell 1, ensuring the sealing and integrity of the shell 1, but also greatly improves the convenience and accuracy of the installation of the wireless communication module. The sealing end plate 11 will effectively protect the wireless communication module, thereby ensuring the stability and reliability of the operation of the wireless communication module.

[0056] Furthermore, if Figures 5 to 8 As shown, a connecting plate 13 is provided on one side of the opening, and the connecting plate 13 is used to limit the contact with the sealing end plate 11 when forming a snap connection. A fixing block 17 is also provided on the connecting plate 13, and the fixing block 17 is provided with a positioning groove 18. A connecting rod 14 is provided at the end of the sealing end plate 11 close to the connecting plate 13, and a pressing block 16 is provided at the end of the connecting rod 14. The pressing block 16 can be embedded in the positioning groove 18 to detachably snap-connect the connecting rod 14 and the fixing block 17, and when the pressing block 16 is pressed, the connecting rod 14 can be elastically deformed to achieve the separation of the connecting rod 14 and the fixing block 17.

[0057] Preferably, the fixing block 17 is further provided with a pressing groove 19, the notch of which is arranged toward the outside of the housing 1, and the pressing groove 19 is arranged in communication with the positioning groove 18, so as to facilitate pressing the pressing block 16 located in the positioning groove 18 through the pressing groove 19, thereby releasing the snap connection between the connecting rod 14 and the fixing block 17. The connecting plate 13 is also connected with a return spring 15, and when the connecting rod 14 and the fixing block 17 are snap-connected, the return spring 15 is compressed and clamped between the connecting plate 13 and the sealing end plate 11. When the pressing block 16 is pressed through the pressing groove 19, under the action of the return spring 15, the sealing end plate 11 can automatically move in a direction away from the connecting plate 13, thereby facilitating the operation of opening the chamber.

[0058] Exemplarily, after the wireless communication module is installed in the housing 1, the operator pushes the sealing end plate 11 to move it toward the side of the connecting plate 13, thereby closing the chamber. During this process, the connecting rod 14 moves accordingly and compresses the reset spring 15 arranged on the outside of the connecting rod 14. As the sealing end plate 11 moves, the pressing block 16 on the other side of the reset spring 15 also approaches the fixed block 17. The fixed block 17 is located in the middle position of the connecting plate 13, and the positioning groove 18 provided thereon corresponds to the pressing block 16. When the sealing end plate 11 abuts against the connecting plate 13, the pressing block 16 will just fit into the positioning groove 18, thereby achieving a firm locking of the sealing end plate 11 and the housing 1.

[0059] When the wireless communication module needs to be taken out, the operator can press the pressing block 16 through the pressing groove 19 to make the pressing block 16 disengage from the positioning groove 18. At this time, the restoring force of the reset spring 15 will push the sealing end plate 11 to move away from the side of the connecting plate 13, preventing the pressing block 16 from entering the positioning groove 18 again, and also facilitating the operator to move the sealing end plate 11. By moving the sealing end plate 11 to separate it from the T-shaped slider 10, the chamber can be opened, so that the wireless communication module can be taken out through the opening.

[0060] Preferably, a damper is integrated in the return spring 15 , and the damper can slow down the compression speed of the return spring 15 , so that the sealing end plate 11 can move more smoothly when gradually abutting against the connecting plate 13 , thereby reducing impact and vibration.

[0061] Furthermore, a heat dissipation hole is provided through the shell 1 , and the heat dissipation hole is connected to the chamber and can enhance the heat dissipation effect in the chamber.

[0062] Specifically, the heat dissipation holes include side heat dissipation holes 25 and bottom heat dissipation holes 26. The side heat dissipation holes 25 are arranged on the outer walls of both sides of the shell 1, and a plurality of side heat dissipation holes 25 are arranged on each outer wall. The side heat dissipation holes 25 not only increase the area of ​​air circulation, but also enable the air to more fully exchange heat with the hot air in the chamber during the flow process, thereby accelerating the dissipation of heat. The bottom heat dissipation holes 26 are arranged on the bottom wall of the shell 1, and their function is to provide an additional heat dissipation channel, so that the hot air in the chamber can not only be discharged through the side heat dissipation holes 25, but also can flow out through the bottom heat dissipation holes 26. This multi-channel heat dissipation design can significantly improve the heat dissipation efficiency, especially when the equipment or components in the chamber generate a lot of heat, it can reduce the temperature more quickly and maintain the stable operation of the equipment.

[0063] Preferably, in order to facilitate maintenance when the wireless function is damaged, a data interface is also provided on the sealing end plate 11, and the data interface can be connected to the wireless communication module arranged in the shell 1 through a signal line, so that the wireless communication module can be conveniently and quickly maintained by using an external device to connect the data interface.
