Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a moisture-proof protective cover for a fuel sensor. Background Art

[0002] A moisture-proof protective cover for a fuel sensor is a device used to protect the fuel sensor in an automobile or other mechanical equipment. Its main function is to prevent moisture, dust and other pollutants from damaging the sensor, so as to ensure its normal operation and extend its service life.

[0003] However, in actual use, there are still the following deficiencies. For example, in the existing moisture-proof protective cover for a fuel sensor, the connection between the sensor body and the equipment cannot be protected. Moisture entering the sensor interior may cause a short circuit or corrosion of the circuit, thus affecting the normal operation of the sensor, resulting in inaccurate measurement data or even failure. Moisture entering the fuel system may cause problems such as fuel pump failure and fuel pipeline blockage. In severe cases, it may cause the vehicle to stall or have insufficient power during driving, increasing the driving safety risk.

[0004] Therefore, the utility model proposes a moisture-proof protective cover for a fuel sensor to solve the above problems. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 - 3 shown, this embodiment provides a technical solution: a moisture-proof protection cover for a fuel sensor, including a sensor body 1, and a protection component 2 is arranged on the sensor body 1; [[ID=...]] [[ID=...]]

[0031] [[ID=...]] Figures 1 - 3 [[ID=...]] [[ID=...]]

[0032] shown, the protection component Figures 1 - 3 2 includes a protection shell 21, a first interface protection shell 22 is fixedly connected to the protection shell 21, a second interface protection shell 24 is arranged on the first interface protection shell 22, a rubber soft plate 26 is fixedly connected to the second interface protection shell 24, a first fixing block 27 is fixedly connected to the second interface protection shell 24, a limiting rod 28 is slidably connected to the first fixing block 27, the limiting rod 28 is fixedly connected to the protection shell 21, a telescopic spring 29 is arranged on the limiting rod 28, the other end of the limiting rod 28 is fixedly connected to a first limiting block 210, a second rubber pad 213 is fixedly connected to the protection shell 21, and sealing gaskets 214 are fixedly connected to the protection shell 21, the first interface protection shell 22 and the second interface protection shell 24. When an operator connects the sensor body 1 to the device, it is first necessary to ensure the firmness and stability of the connection. Subsequently, the protection shell 21 is snapped onto the sensor body 1. Through the cooperation of the first fixing block 27, the limiting rod 28 and the telescopic spring 29, the limiting rod 28 can push the first fixing block 27 and the second interface protection shell 24 to move outwards. This design enables the second interface protection shell 24 and the rubber soft plate 26 fixedly connected thereto to closely fit the connection between the sensor body 1 and the device, forming an effective sealing layer to prevent moisture and other impurities from entering. Through the cooperation of the second rubber pad 213 and the sealing gaskets 214, the use of these components can not only further improve the sealing performance of the sensor body 1 in the protection shell 21, but also effectively block the intrusion of external moisture, thus solving the technical problem that the connection between the sensor body 1 and the device cannot be protected. In the above solution, there is still a problem that when the sensor body 1 is protected, the stable fixation between the protection covers cannot be satisfied. As Figures 1 - 3 It should be noted that there seem to be some incomplete or incorrect tags in the original text, but I have translated it according to the requirements.As shown: A slider 23 is fixedly connected to the first interface protective case 22, and a chute 25 is formed on the second interface protective case 24. The slider 23 is slidably connected in the chute 25. Since the slider 23 is fixedly connected to the first interface protective case 22, the chute 25 is formed on the second interface protective case 24, and the slider 23 is slidably connected in the chute 25, the second interface protective case 24 can be slidably connected to the first interface protective case 22. When the second interface protective case 24 moves, through the cooperation of the slider 23 and the chute 25, it can prevent the first interface protective case 22 from falling off the second interface protective case 24. One end of the telescopic spring 29 is fixedly connected to the protective case 21, and the other end of the telescopic spring 29 is fixedly connected to the first fixing block 27. Since one end of the telescopic spring 29 is fixedly connected to the protective case 21 and the other end of the telescopic spring 29 is fixedly connected to the first fixing block 27, the telescopic spring 29 can provide an elastic force to the second interface protective case 24. An outer case 211 is fixedly connected to the protective case 21, and a first rubber pad 212 is fixedly connected inside the protective case 21. Since the outer case 211 is fixedly connected to the protective case 21, the outer case 211 can protect the first fixing block 27, the limiting rod 28, the telescopic spring 29 and the first limiting block 210. Since the first rubber pad 212 is fixedly connected inside the protective case 21, after the sensor body 1 is placed in the protective case 21, the first rubber pad 212 can buffer the sensor body 1 and prevent the impact on the protective case 21 from affecting the sensor body 1;

[0033] As Figures 1 - 2 shown, a first fixing assembly 3 is provided on the protective case 21. The first fixing assembly 3 includes a second fixing block 31. The second fixing block 31 is fixedly connected to the protective case 21. A first bolt 32 is threadedly connected to the second fixing block 31, and a nut 33 is threadedly connected to the first bolt 32. After the sensor body 1 is placed in the protective case 21, the two protective cases 21 are closed. Subsequently, the first bolt 32 threadedly connected to the second fixing block 31 is rotated and threaded into the nut 33, so that the two protective cases 21 can be fixed;

[0034] As Figures 1 - 2 and Figure 4As shown in the figure, a second fixing component 4 is provided on the outer shell 211. The second fixing component 4 includes a second limiting block 41 and a connecting block 42. The second limiting block 41 is fixedly connected to the outer shell 211. A fixing plate 43 is fixedly connected to the connecting block 42. The fixing plate 43 is slidably connected within the second limiting block 41. The other end of the fixing plate 43 is fixedly connected to a support block 44. A second bolt 45 is threadedly connected to the support block 44. By pushing the connecting block 42, the connecting block 42 drives the fixing plate 43 to slide within the second limiting block 41. When the fixing plate 43 moves to the other half of the outer shell 211, the second bolt 45 threadedly connected to the support block 44 is screwed onto the outer shell 211, enabling the outer shells 211 to be fixed to each other, and enabling the protective cover to be stably fixed.

[0035] Working principle:

[0036] As Figures 1 - 4 shown in the figure, when an operator connects the sensor body 1 to the device, first, it is necessary to ensure the firmness and stability of the connection. Subsequently, the protective shell 21 is snap-fitted onto the sensor body 1. Through the cooperation of the first fixing block 27, the limiting rod 28, and the telescopic spring 29, the limiting rod 28 can push the first fixing block 27 and the second interface protective shell 24 to move outward. This design enables the second interface protective shell 24 and the rubber soft plate 26 fixedly connected thereto to closely fit the connection between the sensor body 1 and the device, forming an effective sealing layer to prevent moisture and other impurities from entering. Through the cooperation of the second rubber pad 213 and the sealing pad 214, the use of these components can not only further improve the sealing performance of the sensor body 1 within the protective shell 21 but also effectively block the intrusion of external moisture. After the sensor body 1 is placed within the protective shell 21, the two protective shells 21 are closed. Subsequently, the first bolt 32 threadedly connected to the second fixing block 31 is screwed into the nut 33, enabling the two protective shells 21 to be fixed. By pushing the connecting block 42, the connecting block 42 drives the fixing plate 43 to slide within the second limiting block 41. When the fixing plate 43 moves to the other half of the outer shell 211, the second bolt 45 threadedly connected to the support block 44 is screwed onto the outer shell 211, enabling the outer shells 211 to be fixed to each other, and enabling the protective cover to be stably fixed, ensuring that the sensor can operate normally even in a harsh environment and improving its service life and reliability.
