Description

Technical Field

[0001] The utility model belongs to the technical field of cam sensors, and particularly relates to a cam sensor with a protection structure. Background Technique

[0002] The camshaft position sensor is a sensing device, also called a synchronous signal sensor. It is a cylinder discrimination and positioning device that inputs the camshaft position signal to the ECU and is the main control signal for ignition control.

[0003] The existing publicly disclosed patent number is CN216745911U, and the public name is a camshaft sensor, which includes a connection module, a plug module, and a function module; the connection module includes a connection frame, and connection protrusions are provided at both ends of the connection frame.

[0004] Although the above camshaft sensor realizes the modular use of the camshaft sensor through the cooperation of the connection module, the plug module, and the function module, and any module in the camshaft sensor can be replaced on the premise of ensuring the normal use of the camshaft sensor, avoiding the defect that when any position of the traditional camshaft sensor with an integrated structure is damaged, the sensor needs to be replaced, which not only avoids waste of resources but also avoids the maintenance cost caused by directly replacing a new camshaft sensor. At the same time, through the combined use of the first sealing member and the second sealing member, it not only ensures the sealing performance of the camshaft sensor but also ensures the connection strength and integrity of the camshaft sensor, facilitating the popularization and use of the product. However, the above cam sensor is not convenient for installation and fixation, and it is not convenient to protect the cam sensor, resulting in the cam sensor being prone to shaking due to the driving of the vehicle, and then the cam sensor colliding.

[0023] Embodiment

[0024] Please refer to Figures 1-4 , the technical solutions provided in this embodiment are as follows:

[0025] A cam sensor with a protective structure, comprising: a mounting plate 1, a universal ball 2 is movably connected to the surface of the mounting plate 1, a connecting plate 3 is fixedly connected to the surface of the universal ball 2, a photoelectric sensor 5 is arranged on one side of the connecting plate 3, a cam disc 6 is mounted on the surface of the photoelectric sensor 5, a signal generator 7 is mounted on the top of the photoelectric sensor 5, a clamping mechanism 4 for clamping the photoelectric sensor 5 is mounted on the surface of the connecting plate 3, protective mechanisms 8 for protecting the photoelectric sensor 5 are mounted on both sides of the surface of the connecting plate 3, and a mounting mechanism 9 is arranged on the surface of the mounting plate 1. The mounting mechanism 9 facilitates the installation of the mounting plate 1. At the same time, the photoelectric sensor 5, the cam disc 6 and the signal generator 7 can be adjusted in angle through the connecting plate 3, so as to change the use angle and direction. The clamping mechanism 4 facilitates the disassembly and maintenance of the photoelectric sensor 5, the cam disc 6 and the signal generator 7. The mounting mechanism 9 can support and protect the photoelectric sensor 5, the cam disc 6 and the signal generator 7, and protect the photoelectric sensor 5, the cam disc 6 and the signal generator 7 when the vehicle shakes.

[0026] Specifically, the clamping mechanism 4 includes two limit posts 401 mounted on the surface of the connecting plate 3. Two moving sliders 402 are slidably connected to the surface of the limit posts 401. A first damper 403 is mounted on the relatively inner surfaces of the two moving sliders 402. A first buffer spring 404 that contacts the two moving sliders 402 is sleeved outside the first damper 403. A first clamping block 405 is fixedly connected to the surface of the upper moving slider 402, and a second clamping block 406 is fixedly connected to the surface of the lower moving slider 402. The inner surface of the first clamping block 405 is adapted to the surface of the signal generator 7, and the inner surface of the second clamping block 406 is adapted to the surface of the photoelectric sensor 5.

[0027] In a specific embodiment of the present utility model, when the photoelectric sensor 5 and the signal generator 7 are respectively clamped on the surfaces of the first clamping block 405 and the second clamping block 406, the first clamping block 405 and the second clamping block 406 will respectively drive the moving sliders 402 to move on the surface of the limit posts 401. The moving sliders 402 will stretch the first damper 403 and the first buffer spring 404. At the same time, the stretching of the first damper 403 and the first buffer spring 404 will generate a reaction force on the moving sliders 402, thereby realizing the clamping of the photoelectric sensor 5 and the signal generator 7.

[0028] Specifically, the protection mechanism 8 includes a protection frame 801 installed on the surface of the connecting plate 3. Two second dampers 802 are installed on the surface of the protection frame 801. A second buffer spring 807 is arranged on the surface of the second damper 802. One end of the inner side of the second damper 802 is fixedly connected to a connecting shaft 803. A connecting member 804 is slidably connected to the surface of the connecting shaft 803. A buffer plate 805 is rotatably connected to one side of the connecting member 804. A protection plate 806 is fixedly connected to the surface of the buffer plate 805.

[0029] In a specific embodiment of the present utility model, when the first clamping block 405 and the second clamping block 406 exert a force on the protection plate 806 or when the photoelectric sensor 5, the cam disc 6 and the signal generator 7 shake, the protection plate 806 will transmit the force to the buffer plate 805. At this time, the buffer plate 805 will transmit the force to the second damper 802 and the second buffer spring 807 through the connecting member 804 and the connecting shaft 803. At this time, under the action of the second damper 802 and the second buffer spring 807, a reaction force will be generated on the first clamping block 405 and the second clamping block 406 through the protection plate 806, thereby ensuring the stability of the photoelectric sensor 5, the cam disc 6 and the signal generator 7 during use and improving the protection effect on the photoelectric sensor 5, the cam disc 6 and the signal generator 7.

[0030] Specifically, the outer surface of the protection plate 806 is convex. A first chute adapted to the connecting shaft 803 is provided on the surface of the second damper 802. A second chute adapted to the connecting member 804 is provided on the surface of the second damper 802.

[0031] In a specific embodiment of the present utility model, when the second damper 802 contracts, it will drive the connecting shaft 803 to move on the surface of the first chute, and at the same time drive the connecting member 804 to move on the surface of the second chute.

[0032] Specifically, the installation mechanism 9 includes a reinforcement plate 901 provided on one side of the installation plate 1 and two fixing nuts 903 provided on one side of the installation plate 1. Two fixing bolts 902 are fixedly connected to the surface of the reinforcement plate 901, and the two fixing nuts 903 are respectively adapted to the two fixing bolts 902.

[0033] In a specific embodiment of the present utility model, by fitting the reinforcement plate 901 to the plane and then screwing the fixing nut 903 onto the surface of the corresponding fixing bolt 902, the reinforcement plate 901 and the installation plate 1 are fixed to the installation surface.

[0034] Working principle: The mounting plate 1 can be conveniently mounted through the mounting mechanism 9. At the same time, the photoelectric sensor 5, the cam disc 6 and the signal generator 7 can be adjusted in angle through the connecting plate 3, so as to change the use angle and direction. When the photoelectric sensor 5 and the signal generator 7 are respectively clamped on the surfaces of the first clamping block 405 and the second clamping block 406, the first clamping block 405 and the second clamping block 406 will respectively drive the moving slider 402 to move on the surface of the limit column 401. The moving slider 402 will stretch the first damper 403 and the first buffer spring 404. At the same time, the stretching of the first damper 403 and the first buffer spring 404 will generate a reaction force on the moving slider 402, so as to clamp the photoelectric sensor 5 and the signal generator 7. When the first clamping block 405 and the second clamping block 406 exert a force on the protection plate 806 or the photoelectric sensor 5, the cam disc 6 and the signal generator 7 shake, the protection plate 806 will transmit the force to the buffer plate 805. At this time, the buffer plate 805 will transmit the force to the second damper 802 and the second buffer spring 807 through the connecting piece 804 and the connecting shaft 803. When the second damper 802 contracts, it will drive the connecting shaft 803 to move on the surface of the first chute, and at the same time drive the connecting piece 804 to move on the surface of the second chute. At this time, under the action of the second damper 802 and the second buffer spring 807, a reaction force will be generated on the first clamping block 405 and the second clamping block 406 through the protection plate 806, so as to ensure the stability of the photoelectric sensor 5, the cam disc 6 and the signal generator 7 during use, and improve the protection effect on the photoelectric sensor 5, the cam disc 6 and the signal generator 7.
