Description

Technical Field

[0001] This utility model relates to the technical field of automotive technology, specifically to an installation structure for an oil position sensor. Background Technology

[0002] A floating oil level sensor detects whether the oil level is below a lower limit level by adjusting the position of a floating body that changes according to the oil level in the oil pan. Some floating oil level sensors have an outer casing that houses the floating body and the sensing element used to detect whether the oil level is below the lower limit level. This type of oil level sensor is configured such that engine oil can flow inside and outside the casing.

[0003] For example, the mounting structure of an oil level sensor with authorization announcement number "CN204827598U" solves the problem that existing oil level sensor mounting structures cannot detect oil levels below the lower limit. The aforementioned design, where oil returns to the oil pan along the mounting portion (inclined surface) of the bracket, easily guides the oil flowing onto the bracket to the front end of the mounting portion. This allows the oil to efficiently return from the front end of the bracket mounting portion to the oil pan and effectively prevents oil from flowing from the bracket into the external interior. Considering the existing oil level sensor mounting structure, where the oil level sensor and bracket are connected, installation and removal require complete removal from inside the oil pan, making it impossible to replace the oil level sensor individually, thus causing inconvenience in maintenance. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing oil level sensor installation structures, and to propose an oil level sensor installation structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for an oil position sensor, comprising a bracket and a sensor, wherein the inner wall of the bracket is machined with threaded holes and through holes, a power connector is installed on the outer wall of the bracket, the output end of the power connector is electrically connected to the sensor, and an installation mechanism is connected to the inner wall of the bracket.

[0006] Preferably, the mounting mechanism includes an internally threaded block, the lower end of which is fixedly connected to the bracket, the inner wall of which is threadedly connected to a fixing screw, the outer wall of which is threadedly connected to the mounting bracket, and the surface of the mounting bracket is machined with grooves.

[0007] Preferably, the inner wall of the groove is slidably connected to the silicone strip, the outer wall of the silicone strip is fixedly connected to the sensor, and a protective mechanism is connected to the upper end of the bracket.

[0008] Preferably, the protective mechanism includes a locking block, the outer wall of which engages with the bracket, the outer wall of which is fixedly connected to a connecting rod, and the upper end of the connecting rod is fixedly connected to the protective cover.

[0009] Preferably, the lower end of the bracket is fixedly connected to the fixing ring, and the outer wall of the fixing ring is fixedly connected to the rubber ring.

[0010] Preferably, the surface of the protective cover is movably connected to the silicone block.

[0011] The present invention proposes an installation structure for an oil level sensor, which has the following advantages: by prying out the rubber block on the protective cover, and using a tool inserted into the through hole to squeeze the locking block, the connecting rod on the protective cover and the locking block are separated from the bracket. By turning the fixing screw through the mounting bracket and disengaging it from the internal thread block, the mounting bracket and the sensor are directly separated from the bracket, eliminating the need to disassemble the bracket and the sensor together. This shortens the installation and disassembly steps and makes maintenance more convenient. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1: Please refer to Figure 1-6 In this embodiment, an oil position sensor mounting structure includes a bracket 1 and a sensor 2. The inner wall of the bracket 1 is machined with threaded holes 3 and through holes 4. A power connector 5 is mounted on the outer wall of the bracket 1. The output end of the power connector 5 is electrically connected to the sensor 2. The sensor 2 is a ZJ-0565 oil sensor, which is used to sense and measure the oil position. An installation mechanism 6 is connected to the inner wall of the bracket 1.

[0021] The mounting mechanism 6 includes an internally threaded block 601, which is fixed to the mounting bracket 603 by a fixing screw 602, so that the mounting bracket 603 is also fixedly installed with the bracket 1. The lower end of the internally threaded block 601 is fixedly connected to the bracket 1. The inner wall of the internally threaded block 601 is threadedly connected to the fixing screw 602, and the outer wall of the fixing screw 602 is threadedly connected to the mounting bracket 603. The surface of the mounting bracket 603 is machined with a groove 604.

[0022] The inner wall of the groove 604 is slidably connected to the silicone strip 7, the outer wall of the silicone strip 7 is fixedly connected to the sensor 2, and the upper end of the bracket 1 is connected to the protective mechanism 8. The connecting rod 802 on the protective cover 803 is inserted into the interior of the bracket 1, and the locking block 801 at the end of the connecting rod 802 is locked onto the bracket 1, so that the protective cover 803 protects the exposed exterior of the bracket 1. The protective mechanism 8 includes the locking block 801, the outer wall of the locking block 801 is locked with the bracket 1, the outer wall of the locking block 801 is fixedly connected to the connecting rod 802, and the upper end of the connecting rod 802 is fixedly connected to the protective cover 803.

[0023] Remove the rubber block 11 from the protective cover 803, and use a tool to insert into the through hole 4 to press the locking block 801, so that the connecting rod 802 and the locking block 801 on the protective cover 803 are separated from the bracket 1. Tighten the fixing screw 602 to pass through the mounting bracket 603 and disengage from the internal thread block 601, so that the mounting bracket 603 and the sensor 2 can be directly separated from the bracket 1. There is no need to disassemble the bracket 1 and the sensor 2 together, which shortens the installation and disassembly steps and makes maintenance more convenient.

[0024] The lower end of the bracket 1 is fixedly connected to the fixing ring 9, the outer wall of the fixing ring 9 is fixedly connected to the rubber ring 10, and the surface of the protective cover 803 is movably connected to the silicone block 11.

[0025] Working principle:

[0026] Assembly stage

[0027] By sliding the silicone strips 7 on both sides of the sensor 1 into the grooves 604 on the mounting bracket 603, and inserting the rubber mounting bracket 603 into the bracket 1, the mounting bracket 603 is aligned with the internal thread block 601. The outer wall of the mounting bracket 603 also fits against the inner side of the bracket 1, ensuring a seal at the connection. The fixing screw 602 is then tightened to pass through the mounting bracket 603 and fix it to the internal thread block 601, thus fixing the mounting bracket 603 and the bracket 1 together.

[0028] Installation and usage phase

[0029] By inserting the bracket 1 into the oil pan to be monitored, the rubber ring 10 on the fixing ring 9 will press against the edge of the oil pan. The external screw is screwed into the threaded hole 3 inside the bracket 1 to fix it to the oil pan. The connecting rod 802 on the protective cover 803 is inserted into the inside of the bracket 1, and the locking block 801 at the end of the connecting rod 802 is locked onto the bracket 1, so that the protective cover 803 protects the exposed exterior of the bracket 1. The power interface 5 is electrically connected to the external device, so that the sensor 2 can monitor the oil level inside the oil pan.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
