In daily airborne detection, maintenance, and repair processes, especially in fault detection and diagnosis, flight data acquisition is extremely important. However, existing equipment is difficult to integrate and miniaturize in terms of size and function, resulting in certain disadvantages in use. When impacted, it only relies on the shell of the equipment for protection, and it is easy for the shell to be damaged by the impact, causing damage to its internal components and affecting normal use. Utility Model Content

[0005] Preferably, the module cover is a heat dissipation fin, which can conduct heat from the inside of the shell to achieve the effect of heat dissipation.
[0006] Preferably, the assembly component includes a bracket and a mounting frame, the bracket is fixed on the surface of the shell, and the mounting frame is provided with two groups, and the two groups of mounting frames are fixed by a cross beam, and a resistance plate is slidably installed on the inner side of the mounting frame, and the resistance plate is penetrated by the top limit plate and fixed to the top limit plate, and a connecting spring is fixed on the inner side of the mounting frame.
[0007] Preferably, one end of the connecting spring away from the mounting bracket is fixed to the top limit plate, the contact plate is penetrated by the bottom limit plate, and the bottom limit plate is slidably installed on the inner side of the mounting bracket, and a return spring is fixed to the bottom of the bottom limit plate, and one end of the return spring away from the bottom limit plate is fixed to the inner side of the mounting bracket. The mounting bracket is first fixed to the position where it needs to be installed on the body, and then the bracket on the surface of the shell is inserted into the mounting bracket to complete the installation. When the shell is impacted, the bracket can be moved to the side close to the mounting bracket to squeeze the connecting spring. At the same time, the shaking generated by the shell will be transmitted to the bottom limit plate and the top limit plate. The bottom limit plate can apply pressure to the return spring, causing the return spring to deform and absorb energy of the impact on the shell, thereby avoiding deformation and damage of the shell due to impact, causing damage to its internal components and affecting normal operation.

The contact plate can push the two groups of sliders to move away from each other through the support rod to stretch the tension spring, thereby further playing a buffering role. When the contact plate is reset, the contact plate can contact the rubber block. Through the friction between the rubber block and the contact plate, the speed of resetting the contact plate is slowed down, thereby avoiding the contact plate resetting too fast, which causes the shell to vibrate.
[0009] Preferably, the top of the contact plate and the end of the top limit plate away from the connecting spring are both arranged as beveled surfaces. When the bracket is inserted from the top of the mounting frame, the bracket can contact the beveled surface of the contact plate to push the contact plate to move toward the side close to the connecting spring. When the bracket moves downward a certain distance, the bracket can contact the beveled surface of the top limit plate to push the top limit plate to move, which will not affect the normal insertion of the bracket.

[0013] 2. The signal acquisition and storage device, through the assembly components and auxiliary components, when the shell is impacted, the bracket contacts the contact plate, so that the contact plate moves and squeezes the connecting spring. At the same time, the shaking of the shell will be transmitted to the bottom limit plate and the top limit plate. The bottom limit plate can apply pressure to the reset spring, so that the reset spring is deformed to absorb the impact on the shell. At the same time, the contact plate can push the two sets of sliders to move in opposite directions through the support rod to stretch the tension spring, thereby further playing a buffering role. When the contact plate is reset, the contact plate can contact the rubber block. The friction between the rubber block and the contact plate can slow down the resetting speed of the contact plate, thereby avoiding the contact plate resetting too fast, causing the shell to vibrate, and avoiding the shell to be deformed and damaged by impact, causing damage to its internal components and affecting normal operation.

[0018] like Figure 1-Figure 3As shown, the utility model provides a technical solution: a signal acquisition and storage device, including a shell 1, the inside of the shell 1 is fixed with a power adapter board 6, a power board assembly 8, and a signal acquisition processing unit 9 by bolts, the power adapter board 6 is provided with an internal cable assembly 7, the signal acquisition processing unit 9 is provided with an external whole machine cable 10, the top of the shell 1 is fixed with a module cover plate 12 by bolts, the bottom of the shell 1 is fixed with a module outer cover 5 by bolts, and a silicone pad 11, a sealing rubber ring 13 and an outer cover adapter plate are provided between the shell 1 and the module outer cover 5 14. The back of the shell 1 is provided with an assembly component 3 for protecting the entire device. The power adapter board 6, the internal cable assembly 7, the power board assembly 8 and the signal acquisition processing unit 9 are located inside a sealed cavity formed by the module outer cover 5, the silicone pad 11, the sealing rubber ring 13, the outer cover adapter board 14, the shell 1 and the module cover 12 to ensure that it can work in harsh environments. The shell 1 is made of hard stainless steel to ensure the stability and safety of its internal components. The module cover 12 is a heat dissipation fin that can conduct the heat inside the shell 1 to achieve the effect of heat dissipation.
[0019] The assembly component 3 includes a bracket 31 and a mounting frame 32. The bracket 31 is fixed on the surface of the shell 1. The mounting frame 32 is provided with two groups. The two groups of mounting frames 32 are fixed by a crossbeam 33. A resistance plate 34 is slidably installed on the inner side of the mounting frame 32. The resistance plate 34 is penetrated by the top limit plate 35 and fixed to the top limit plate 35. A connecting spring 37 is fixed on the inner side of the mounting frame 32. The end of the connecting spring 37 away from the mounting frame 32 is fixed to the top limit plate 35. The resistance plate 34 is penetrated by the bottom limit plate 38. The bottom limit plate 38 is slidably installed on the inner side of the mounting frame 32. A reset spring 36 is fixed at the bottom of the bottom limit plate 38. The reset spring 36 is away from the bottom limit plate One end of 38 is fixed to the inner side of the mounting frame 32. The mounting frame 32 is first fixed to the position where it needs to be installed on the body, and then the bracket 31 on the surface of the shell 1 is inserted into the mounting frame 32 to complete the installation. When the shell 1 is impacted, the bracket 31 can be moved to the side close to the mounting frame 32 to squeeze the connecting spring 37. At the same time, the shaking generated by the shell 1 will be transmitted to the bottom limit plate 38 and the top limit plate 35. The bottom limit plate 38 can apply pressure to the reset spring 36, causing the reset spring 36 to deform and absorb the impact on the shell 1, thereby preventing the shell 1 from being deformed and damaged by the impact, causing damage to its internal components and affecting normal operation.
[0020] An auxiliary component 4 for cooperating with the assembly component 3 is arranged on the inner side of the mounting frame 32. The auxiliary component 4 includes a slider 41. The slider 41 is slidably mounted on the inner side of the mounting frame 32. Two groups of sliders 41 are arranged. A tension spring 42 is fixed between the two groups of sliders 41. A support rod 43 is hinged on the side of the slider 41 close to the contact plate 34. The end of the support rod 43 away from the slider 41 is hinged to the contact plate 34. A rubber block 44 is fixed on the surface of the bottom limit plate 38. When the shell 1 is impacted, the bracket 31 is moved closer to the mounting frame 32. When one side of the mounting frame 32 moves, the bracket 31 abuts against the abutment plate 34, causing the abutment plate 34 to move. The abutment plate 34 can push the two sets of sliders 41 to move in opposite directions through the support rod 43 to stretch the tension spring 42, thereby further playing a buffering role. When the abutment plate 34 is reset, the abutment plate 34 can abut against the rubber block 44. The friction between the rubber block 44 and the abutment plate 34 can slow down the resetting speed of the abutment plate 34, thereby preventing the abutment plate 34 from resetting too quickly and causing the housing 1 to vibrate.
[0021] The top of the contact plate 34 and the end of the top limit plate 35 away from the connecting spring 37 are both set as beveled surfaces. When the bracket 31 is inserted from the top of the mounting frame 32, the bracket 31 can contact the beveled surface of the contact plate 34 to push the contact plate 34 to move toward the side close to the connecting spring 37. After the bracket 31 moves downward for a certain distance, the bracket 31 can contact the beveled surface of the top limit plate 35 to push the top limit plate 35 to move, which will not affect the normal insertion of the bracket 31.
[0022] Based on the above embodiment, first, fix the crossbeam 33 at the position where the body needs to be installed by bolts, and insert the bracket 31 on the surface of the shell 1 from the top of the mounting frame 32. The bracket 31 can abut against the oblique surface of the abutment plate 34 to push the abutment plate 34 to move toward the side close to the connecting spring 37. After the bracket 31 moves downward for a certain distance, the bracket 31 can abut against the oblique surface of the top limit plate 35 to push the top limit plate 35 to move, which will not affect the normal insertion of the bracket 31. After the bracket 31 is fully inserted, the installation of the entire device is completed.
[0023] When the shell 1 is impacted and moves with the bracket 31 to the side close to the mounting bracket 32, the bracket 31 abuts against the abutment plate 34, causing the abutment plate 34 to move and squeeze the connecting spring 37. At the same time, the shaking generated by the shell 1 will be transmitted to the bottom limit plate 38 and the top limit plate 35. The bottom limit plate 38 can apply pressure to the reset spring 36, causing the reset spring 36 to deform and absorb the impact on the shell 1. At the same time, the abutment plate 34 can push the two sets of sliders 41 to move in opposite directions through the support rod 43 to stretch the tension spring 42, thereby further playing a buffering role. When the abutment plate 34 is reset, the abutment plate 34 can abut against the rubber block 44. Through the friction between the rubber block 44 and the abutment plate 34, the speed of resetting the abutment plate 34 is slowed down, so as to avoid the abutment plate 34 resetting too fast, causing the shell 1 to vibrate, and to avoid the shell 1 being deformed and damaged by the impact, causing damage to its internal components and affecting normal operation.
[0024] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
