[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.

[0022] Reference Figures 1 to 7 As shown, a fuel pump bracket integrated module suitable for different oil levels in this embodiment includes a pump core bracket 1, a sensor bracket 2 positioned on the outer wall of the pump core bracket 1, and an oil level sensor assembly 3 installed in the sensor bracket 2;

[0023] Based on the above-mentioned prior art, a slot frame 11 is integrally formed on the outer wall of the pump core bracket 1. The slot frame 11 is U-shaped and its two opposite side walls are provided with limiting grooves for partial insertion of the adjustment frame 21. The two opposite sides of the slot frame 11 are parallel to the height direction of the pump core bracket 1 and the bottom side of the slot frame 11 is parallel to the width direction of the pump core bracket 1. A bracket elastic buckle 12 located in the inner cavity of the slot frame 11 is also integrally formed on the outer wall of the pump core bracket 1. The cross-section of the bracket elastic buckle 12 in the width direction of the pump core bracket 1 is a right-angled trapezoid and the hypotenuse faces the opening of the slot frame 11. The outer wall of the sensor bracket 2 is detachably connected with an adjustment frame 21 that can be inserted into the slot frame 11. The adjustment frame 21 includes a first transverse rib 22, a first longitudinal rib 23, a second transverse rib 24 and a second longitudinal rib 25 connected in sequence head to tail. The lengths of the first transverse rib 22, the first longitudinal rib 23, the second transverse rib 24 and the second longitudinal rib 25 are similar or the same, then the adjustment frame 21 The overall outline is close to or equal to a square. Through holes or countersunk holes for screws to be inserted are provided at the four corners of the steering frame 21. Threaded holes for screw ends to be screwed in are provided on the outer wall of the sensor bracket 2. The steering frame 21 can be positioned on the outer wall of the sensor bracket 2 by screw fastening. The first transverse rib 22 and the first longitudinal rib 23 are both straight. The second transverse rib 24 and the second longitudinal rib 25 are partially bent to form a first compensation groove 241 and a second compensation groove 251, respectively. The first compensation groove 241 and the second compensation groove 251 are both convex to the inner cavity of the steering frame 21. The widths of the first compensation groove 241 and the second compensation groove 251 are both greater than the width of the bracket elastic buckle 12. The steering frame 21 is mounted on the outer wall of the sensor bracket 2. The length directions of the first transverse rib 22 and the second transverse rib 24 are parallel to the width direction of the sensor bracket 2. The length directions of the first longitudinal rib 23 and the second longitudinal rib 25 are parallel to the height direction of the sensor bracket 2.

[0024] During the installation process, the oil level sensor assembly 3 is installed in the sensor bracket 2. There are two installation methods for the adjustment frame 21 and the slot frame 11. First, the second transverse rib 24 is directed toward the bottom of the slot frame 11, and then the adjustment frame 21 is installed in the inner cavity of the slot frame 11. In the process of moving the adjustment frame 21 into the slot frame 11, the bracket elastic buckle 12 first enters the inner cavity of the first compensation groove 241, and then the inclined surface of the bracket elastic buckle 12 slides with the groove bottom edge of the first compensation groove 241. The bracket elastic buckle 12 undergoes elastic deformation and the second transverse rib 24 partially deforms and moves away from the sensor bracket 2 until the bracket elastic buckle 12 passes over the bottom part of the first compensation groove 241. The bracket elastic buckle 12 restores its elastic deformation and the second transverse rib 24 partially restores its deformation. Then the bracket elastic buckle 12 is located in the inner cavity of the adjustment frame 21 and the groove bottom part of the first compensation groove 241 is deformed. Limit, at this time, the second transverse rib 24 touches the bottom of the slot frame 11; secondly, the second longitudinal rib 25 is directed toward the bottom of the slot frame 11, and then the adjustment frame 21 is installed into the inner cavity of the slot frame 11. In the process of moving the adjustment frame 21 into the slot frame 11, the bracket elastic buckle 12 first enters the inner cavity of the second compensation groove 251, and then the inclined surface of the bracket elastic buckle 12 slides with the groove bottom edge of the second compensation groove 251, the bracket elastic buckle 12 is elastically deformed and the second longitudinal rib 25 is partially deformed and moves away from the sensor bracket 2, until the bracket elastic buckle 12 passes over the bottom part of the second compensation groove 251, the bracket elastic buckle 12 restores the elastic deformation and the second longitudinal rib 25 partially restores the deformation, then the bracket elastic buckle 12 is located in the inner cavity of the adjustment frame 21 and limits the groove bottom part of the second compensation groove 251, at this time, the second longitudinal rib 25 touches the groove bottom of the slot frame 11;

[0025] Compared with the prior art, such a design can rotate the sensor bracket 2 by 90° so that the oil level sensor assembly 3 has two installation modes relative to the pump core bracket 1, so that the assembler can adjust the state of the oil level sensor assembly 3 according to actual needs to be suitable for oil level monitoring under different vehicle models, thereby improving versatility and indirectly reducing the production cost of the manufacturer; the design of the first compensation groove 241 and the second compensation groove 251 can ignore the width size limitation of the second transverse rib 24 or the second longitudinal rib 25 compared to the design of the bracket elastic buckle 12 directly buckling with the second transverse rib 24 or the second longitudinal rib 25 in a straight state, so as to be suitable for different The second transverse rib 24 or the second longitudinal rib 25 of the same width improves the versatility. At the same time, the design of the first compensation groove 241 or the second compensation groove 251 for the bracket elastic buckle 12 to enter can play a guiding role for the adjustment frame 21. Furthermore, the first compensation groove 241 and the second compensation groove 251 increase the structural complexity of the corresponding second transverse rib 24 and the second longitudinal rib 25, so that when the second transverse rib 24 or the second longitudinal rib 25 contacts the bracket elastic buckle 12 and undergoes elastic deformation, the local deformation capacity of the second transverse rib 24 and the second longitudinal rib 25 is improved, thereby reducing the wear of the second transverse rib 24 and the second longitudinal rib 25.

[0026] As a specific implementation of the improvement, due to the processing error, the heights of the first compensation groove 241 and the second compensation groove 251 are different, so at least one of the two installation methods will cause the steering frame 21 to move in the slot frame 11, which will affect the monitoring accuracy of the oil level sensor assembly 3. To solve the above problem, refer to Figure 3 , Figure 6 and Figure 7 As shown, at both ends of the first transverse rib 22, a stretching portion 221 and a limiting portion 222 are integrally formed, which can contact with the two end surfaces of the slot frame 11. The stretching portion 221 and the limiting portion 222 extend along the length direction of the first transverse rib 22. The height of the inner cavity of the first compensation groove 241 is less than the height of the inner cavity of the second compensation groove 251. In the installation method in which the second longitudinal rib 25 is directed toward the bottom of the slot frame 11, after the limiting portion 222 and one end of the second transverse rib 24 simultaneously contact with the bottom of the slot frame 11, the bracket elastic buckle 1 2 enters the inner cavity of the steering frame 21 and limits the bottom of the second compensation groove 251. The stretching portion 221 is partially located outside the slot frame 11. This design ensures that the bottom of the steering frame 21 is limited by the bottom of the slot frame 11 to move downward, while the bracket elastic buckle 12 limits the upward movement of the steering frame 21. The structure is compact and the position of the steering frame 21 in the slot frame 11 is fixed. The design that the stretching portion 221 is partially located outside the slot frame 11 makes it easy for the user to pull the stretching portion 221 to take out or adjust the steering frame 21;

[0027] In the installation method in which the second transverse rib 24 is directed toward the bottom of the slot frame 11, after the stretching portion 221 and the limiting portion 222 respectively contact the two end surfaces of the slot frame 11, the bracket elastic buckle 12 enters the inner cavity of the adjustment frame 21 and limits the bottom portion of the first compensation groove 241. This design ensures that the bracket elastic buckle 12 limits the upward movement of the adjustment frame 21 while the stretching portion 221 and the limiting portion 222 both contact the slot frame 11. The structure is compact and the position of the adjustment frame 21 in the slot frame 11 is fixed. The design that the stretching portion 221 and the limiting portion 222 are both located outside the slot frame 11 makes it easy for the user to push the adjustment frame 21 into place.

[0028] As a specific implementation method of the improvement, refer to Figure 3 , Figure 6 and Figure 7 As shown, the stretching portion 221 is L-shaped. Such a design allows the stretching portion 221 to be outlined on one end of the slot frame 11 when the second longitudinal rib 25 is installed toward the bottom of the slot frame 11, thereby serving as a standard for whether the adjustment frame 21 has been moved into place, or making it easier for the installer to apply a pulling force to the adjustment frame 21.

[0029] As a specific implementation method of the improvement, refer to Figure 6 As shown, the width of the limiting portion 222 extending along the width direction of the first transverse rib 22 is greater than the width of the stretching portion 221 extending along the width direction of the first transverse rib 22, and there is a height difference between the two end surfaces of the slot frame 11. Such a design can increase the contact area between the limiting portion 222 and the bottom of the slot frame 11, indirectly improving the force bearing capacity and resistance to deformation of the adjustment frame 21. At the same time, because the length of the limiting portion 222 is less than the length of the stretching portion 221, increasing the width of the limiting portion 222 can improve the structural stability of the limiting portion 222. When the limiting portion 222 touches the end of the slot frame 11, the limiting portion 222 has a strong shear resistance.

[0030] As a specific implementation of the improvement, due to the size processing error, the maximum width of the inner cavity of the slot frame 11 is greater than the maximum distance between the first transverse rib 22 and the second transverse rib 24, and there is a problem that the adjustment frame 21 moves left and right relative to the slot frame 11. To solve the above problem, refer to Figure 3 , Figure 6 and Figure 7 As shown, a plurality of first pre-tightening blocks 223 are provided on the outer wall of the first transverse rib 22, which are distributed along the length direction of the first transverse rib 22 and can contact the inner wall of the slot frame 11. The end surface of the first pre-tightening block 223 facing the bottom of the slot frame 11 is an inclined surface that can slide with the end edge of the slot frame 11. Such a design can make up for the gap between the slot frame 11 and the adjustment frame 21, so that the adjustment frame 21 is compactly connected to the slot frame 11, thereby improving the connection stability of the plug-in.

[0031] As a specific implementation of the improvement, due to the size processing error, the maximum width of the inner cavity of the slot frame 11 is greater than the maximum distance between the first longitudinal rib 23 and the second longitudinal rib 25, and there is a problem that the adjustment frame 21 moves left and right relative to the slot frame 11. To solve the above problem, refer to Figure 3 , Figure 6 and Figure 7 As shown, a plurality of second pre-tightening blocks 252 are arranged on the outer wall of the second longitudinal rib 25, which are distributed along the length direction of the second longitudinal rib 25 and can contact the inner wall of the slot frame 11. The end surface of the second pre-tightening block 252 facing the bottom of the slot frame 11 is an inclined surface that can slide with the end edge of the slot frame 11. Such a design can make up for the gap between the slot frame 11 and the adjustment frame 21, so that the adjustment frame 21 is compactly connected to the slot frame 11, thereby improving the connection stability of the plug-in.

[0032] As a specific implementation method of the improvement, refer to Figure 2 and Figure 5 As shown, a spring hook 31 is provided on the oil level sensor assembly 3, and a clamping hole 21 for the spring hook 31 to be engaged is opened on the inner wall of the sensor bracket 2. When the oil level sensor assembly 3 is installed in the sensor bracket 2, the spring hook 31 is locked with the clamping hole 21. Such a design can ensure that the oil level sensor assembly 3 is stably limited in the sensor bracket 2, and prevent the oil level sensor assembly 3 from escaping from the sensor bracket 2.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
