[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] Reference below Figure 1-Figure 4 An oil level sensor 100 for a vehicle according to an embodiment of the present invention is described.

[0029] like Figure 1-Figure 4 As shown, the oil level sensor 100 according to the embodiment of the present invention includes: a bracket 10 , a sliding piece 20 , a resistor 30 and a float 40 .

[0030] The bracket 10 is arranged on the fuel tank of the vehicle, and the bracket 10 has a height direction (i.e. Figure 1 The slide 11 extends in the Z direction (as shown in the figure); the slide 20 and the resistor 30 are both arranged on the bracket 10, and the slide 20 and the resistor 30 are both extended in the height direction of the bracket 10, and the slide 20 and the resistor 30 are respectively connected to the controller of the vehicle through the wire 46; the float 40 is electrically connected to the slide 20 and the resistor 30, and the float 40 cooperates with the slide 11 and can float along the extension direction of the slide 11.

[0031] The bracket 10 is connected to the fuel tank of the vehicle. As some embodiments of the present application, the bracket 10 is connected to the fuel tank of the vehicle by welding. As some embodiments of the present application, the bracket 10 is connected to the fuel tank of the vehicle by snapping. The bracket 10 has a slide groove 11, and the slide groove 11 is arranged along the height direction of the bracket 10 (i.e. Figure 1 The Z direction as shown) is extended.

[0032] The sliding piece 20 and the resistor piece 30 are both arranged on the bracket 10. As some embodiments of the present application, for example Figure 4 As shown, the bracket 10 has two Figure 1 The slide 20 and the resistor 30 are respectively arranged in the two grooves 12, and the slide 20 and the resistor 30 are arranged along the height direction of the bracket 10 (i.e. Figure 1In some embodiments of the present application, the slider 20 and the resistor 30 are arranged parallel to each other.

[0033] Among them, the controller of the vehicle can be but is not limited to an engine controller, a vehicle controller, etc. As some embodiments of the present application, the controller of the vehicle is an engine controller.

[0034] The slide 20 and the resistor 30 are connected to the vehicle controller through the wire 46 respectively, and the float 40 is electrically connected to the slide 20 and the resistor 30. That is to say, the slide 20, the resistor 30, the float 40 and the controller can form a closed loop. The float 40 can cooperate with the slide groove 11 of the bracket 10, and the float 40 can float along the extension direction of the slide groove 11, so that the float 40 can float up with the increase of the liquid level in the vehicle tank, or float down with the decrease of the liquid level in the vehicle tank. The floating of the float 40 along the extension direction of the slide groove 11 can change the contact position of the float 40 and the resistor 30, so that the controller can obtain the resistance change of the resistor 30. By calibrating the oil volume information corresponding to each resistance value, the current fuel volume can be detected through the resistance change of the resistor 30.

[0035] It should be noted that, by arranging the bracket 10 on the fuel tank, the oil level sensor 100 and the fuel pump can be separated and arranged, which can improve the versatility of the oil level sensor. In addition, by electrically connecting the float 40, the slide 20 and the resistor 30, and connecting the slide 20 and the resistor 30 to the vehicle controller through the wire 46 respectively, the float 40, the slide 20, the resistor 30 and the controller can form a loop, which can make the design of the oil level sensor 100 reasonable and easy to assemble. In addition, when the liquid level height of the vehicle tank changes, the float 40 can move along the height direction of the bracket 10 (that is, the height direction of the tank), so that the contact position of the float 40 and the resistor 30 can be changed, so that the controller can obtain the resistance change of the resistor 30 and detect the current fuel amount.

[0036] During the floating process of the float 40 , the wire 46 will not move with the float 40 , which can reduce the risk of the wire 46 getting entangled itself and the risk of the wire 46 and the wire 46 contacting other components.

[0037] Therefore, by arranging the bracket 10 on the fuel tank, the oil level sensor 100 and the fuel pump can be separated and arranged, which can improve the versatility of the oil level sensor 100. By extending the slide 20 and the resistor 30 along the height direction of the bracket 10 and electrically connecting the float 40 to the slide 20 and the resistor 30, the design of the oil level sensor 100 can be reasonable and easy to assemble. In addition, during the floating process of the float 40, the wire 46 will not move with the float 40, which can reduce the risk of the wire 46 being entangled and the wire 46 contacting other components, which is beneficial to improving the safety of the oil level sensor 100.

[0038] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, there are multiple chutes 11, and the float 40 includes a float body 41, multiple connecting rods 42 and a connecting piece 43. The connecting piece 43 is electrically connected to the slide 20 and the resistor 30. The multiple connecting rods 42 are connected between the float body 41 and the connecting piece 43, and the multiple connecting rods 42 are respectively arranged in the multiple chutes 11.

[0039] The number of the slide grooves 11 is multiple, and the number of the slide grooves 11 can be but not limited to two, three, four, etc. As some embodiments of the present application, the number of the slide grooves 11 is two, and the two slide grooves 11 are along the height direction of the bracket 10 (i.e. Figure 1 The Z direction as shown) is extended.

[0040] The float 40 includes a float body 41, a connecting rod 42 and a connecting piece 43, wherein the number of the connecting rods 42 is multiple, and the number of the connecting rods 42 can be but is not limited to two, three, four, etc. Specifically, the number of the connecting rods 42 is the same as the number of the slide grooves 11 and corresponds one to one. As some embodiments of the present application, the number of the connecting rods 42 is two, and the two connecting rods 42 are connected between the float body 41 and the connecting piece 43.

[0041] The connecting piece 43 is electrically connected to the sliding piece 20 and the resistor piece 30, that is, the float 40 can be electrically connected to the sliding piece 20 and the resistor piece 30 through the connecting piece 43. As some embodiments of the present application, the connecting piece 43 can directly contact the sliding piece 20 and the resistor piece 30 respectively so that the connecting piece 43 is electrically connected to the sliding piece 20 and the resistor piece 30.

[0042] The connecting rod 42 is connected to the float body 41. As some embodiments of the present application, the connecting rod 42 and the float body 41 are constructed as an integrally formed part. The integrally formed part has good structural strength. By constructing the connecting rod 42 and the float body 41 as an integrally formed part, the probability of separation of the connecting rod 42 and the float body 41 can be reduced, which is beneficial to improving the connection strength between the connecting rod 42 and the float body 41.

[0043] As some embodiments of the present application, the connecting rod 42 and the float body 41 are constructed as separate parts. By constructing the connecting rod 42 and the float body 41 as separate parts, the difficulty of manufacturing the float 40 can be reduced, which is conducive to improving production efficiency.

[0044] The connecting rod 42 is connected to the connecting piece 43. As some embodiments of the present application, the end of the connecting rod 42 is connected to the surface of the connecting piece 43 facing the connecting rod 42. As some embodiments of the present application, the connecting piece 43 may have a mounting hole 45, and the connecting rod 42 is passed through the mounting hole 45 and connected to the connecting piece 43.

[0045] Multiple connecting rods 42 are respectively arranged in multiple slide grooves 11. Specifically, the number of connecting rods 42 is the same as the number of slide grooves 11 and is arranged one-to-one. As some embodiments of the present application, two connecting rods 42 are respectively arranged in two slide grooves 11, and the connecting rods 42 can move along the extension direction of the slide groove 11.

[0046] It should be noted that the material of the float body 41 and the connecting rod 42 may be, but not limited to, non-metallic materials such as plastic, and the material of the connecting piece 43 may be, but not limited to, conductive metal materials.

[0047] By connecting the plurality of connecting rods 42 between the float body 41 and the coupling plate 43 and respectively arranging the plurality of connecting rods 42 in the plurality of slide grooves 11 , the probability of the float 40 rotating during floating can be reduced, which is beneficial to improving the measurement accuracy of the oil level sensor 100 .

[0048] In some embodiments of the present invention, Figure 1 As shown, along the first direction (i.e. Figure 1 The float body 41 and the connecting piece 43 are respectively located on both sides of the bracket 10. The first direction (i.e. Figure 1 The X direction shown) and the height direction of the bracket 10 (i.e. Figure 1 The Z direction shown is perpendicular to the axis.

[0049] Among them, along the first direction (i.e. Figure 1 The bracket 10 has two opposite sides, the float body 41 is located on one side of the bracket 10, the connecting piece 43 is located on the other side of the bracket 10, and the connecting rod 42 is connected between the float body 41 and the connecting piece 43. Specifically, the connecting rod 42 can be connected along the first direction (i.e. Figure 1 The connecting rod 42 extends in the X direction as shown in the figure, and the two ends of the connecting rod 42 are connected to the float body 41 and the connecting piece 43 respectively. Figure 1 The X direction shown) and the height direction of the bracket 10 (i.e. Figure 1 The Z direction shown) are perpendicular to each other.

[0050] By locating the float body 41 and the connecting piece 43 on both sides of the bracket 10 along the first direction, the structural design of the float 40 can be reasonably designed, and the connection between the wire 46 and the float 40 and the float body 41 can be arranged on opposite sides of the bracket 10, respectively, which can reduce the difficulty of arranging the wire 46, reduce the risk of the float 40 turning over, and reduce the risk of the wire 46 and the float body 41 being entangled, which is beneficial to improving the reliability of the oil level sensor 100.

[0051] In some embodiments of the present invention, Figure 2 As shown, the connecting piece 43 has two contacts 431 , and the two contacts 431 are in contact with the sliding piece 20 and the resistor piece 30 respectively, so that the connecting piece 43 is electrically connected to the sliding piece 20 and the resistor piece 30 .

[0052] Among them, the material of the contact 431 can be but is not limited to precious metal materials such as silver and gold. As some embodiments of the present application, the material of the contact 431 is metallic silver. The two contacts 431 are respectively in contact with the slider 20 and the resistor 30 and are respectively electrically connected to the slider 20 and the resistor 30, so that the connecting piece 43 is respectively electrically connected to the slider 20 and the resistor 30, and is connected to the controller through the wire 46 to form a closed loop.

[0053] By making the two contacts 431 contact with the slide 20 and the resistor 30 respectively, the connecting piece 43 can be electrically connected to the slide 20 and the resistor 30, and the connecting piece 43, the slide 20, the resistor 30 and the controller can form a reliable circuit, which is beneficial to improving the reliability of the oil level sensor 100.

[0054] In some embodiments of the present invention, Figure 2 As shown, the outer surface of the contact 431 is constructed into an arc shape, wherein the arc shape may be, but is not limited to, a circular arc shape or an elliptical arc shape. By constructing the outer surface of the contact 431 into an arc shape, the connecting piece 43 can be in stable and smooth sliding contact with the sliding piece 20 and the resistor piece 30, thereby reducing the degree of wear of the contact 431, the sliding piece 20 and the resistor piece 30, and helping to increase the service life of the oil level sensor 100.

[0055] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, along the height direction of the bracket 10 (ie Figure 1 The upper end of the slide groove 11 (in the Z direction shown in the figure) is open. By opening the upper end of the slide groove 11, the connecting rod 42 can be assembled from the open position of the upper end of the slide groove 11, which can facilitate the assembly of the float 40 to the bracket, reduce the difficulty of assembling the oil level sensor 100, and help improve the assembly efficiency of the oil level sensor 100.

[0056] In some embodiments of the present invention, Figure 4 As shown, the bracket 10 has two grooves 12, and the slide 20 and the resistor 30 are respectively arranged in the two grooves 12. By arranging the slide 20 and the resistor 30 in the two grooves 12, the slide 20 and the resistor 30 can be easily fixed to the bracket 10, and the assembly firmness of the slide 20 and the resistor 30 can be improved, and the probability of interference between the slide 20 and the resistor 30 and other parts can be reduced, which is beneficial to improving the reliability of the oil level sensor 100. In addition, by arranging the slide 20 and the resistor 30 in the two grooves 12, the space occupied by the oil level sensor 100 can be reduced, which is beneficial to improving space utilization.

[0057] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the slide 20 and the resistor 30 are respectively arranged on both sides of the slide slot 11, wherein the number of the slide slots 11 may be multiple, for example, the number of the slide slots 11 may be but not limited to two, three, etc., and the multiple slide slots 11 may be arranged at intervals, and along the direction in which the multiple slide slots 11 are arranged at intervals, the slide 20 and the resistor 30 may be respectively arranged on both sides of the slide slot 11. By respectively arranging the slide 20 and the resistor 30 on both sides of the slide slot 11, the slide 20 and the resistor 30 may be arranged at intervals, which can reduce the probability of the wire 46 being entangled during the movement of the float 40, and is conducive to improving the reliability of the oil level sensor 100.

[0058] In some embodiments of the present invention, along the height direction of the bracket 10 (i.e. Figure 1 The bracket 10 is connected to the top wall and the bottom wall of the oil tank by welding. By making the two opposite ends of the bracket 10 abut against the top wall and the bottom wall of the oil tank, the bracket 10 can play a supporting role, which is beneficial to improve the structural strength of the oil tank and reduce the risk of collapse and deformation of the oil tank due to impact.

[0059] According to the vehicle of the embodiment of the present invention, including the oil level sensor 100 of the vehicle of the above-mentioned embodiment, by arranging the bracket 10 on the fuel tank, the oil level sensor 100 and the fuel pump can be separated and arranged, which can improve the versatility of the oil level sensor 100. By extending the slide 20 and the resistor 30 along the height direction of the bracket 10 and electrically connecting the float 40 to the slide 20 and the resistor 30, the design of the oil level sensor 100 can be reasonable and easy to assemble. In addition, during the floating process of the float 40, the wire 46 will not move with the float 40, which can reduce the risk of the wire 46 being entangled and the wire 46 contacting other components, which is beneficial to improving the safety of the oil level sensor 100.
