Description

TECHNICAL FIELD

[0001] The utility model relates to the positioning related technical field especially, relates to a sensor assembly positioning tool. BACKGROUND

[0002] With the rapid development of automobile industry, sensor technology plays a vital role in modern cars, they are widely used in engine control, safety systems, vehicle body stability control, environmental monitoring and other aspects. As the core component of these systems, the accurate installation of sensor assembly is crucial to ensure the performance and safety of the car. However, the traditional sensor assembly method adopts fasteners such as bolts for connection, which faces a series of challenges in this process, especially on the complex body frame structure.

[0003] The body frame design often contains a large number of curved surfaces and irregular shapes to adapt to the aesthetics, structural strength and aerodynamic needs of the vehicle. Although this design optimizes the overall performance of the vehicle, it brings inconvenience to the installation of the sensor. Specifically, the sensor assembly needs to be fixed to the predetermined position on the vehicle body through fasteners such as bolts, which requires high-precision alignment during installation to ensure that the bolt holes can be accurately matched.

[0004] In actual operation, due to the curved surface characteristics of the body frame, the traditional installation method often requires the operator to stand at a high position and perform hole centering through visual and manual operation. This process not only consumes time and effort, but also is prone to inaccurate alignment due to visual errors or improper operation, which affects the installation quality of the sensor and the final performance of the vehicle. In addition, high-altitude work also increases the safety risk of the operator, which is not conducive to the improvement of production efficiency and working environment. SUMMARY

[0005] In order to overcome at least one of the defects of the prior art described above, the utility model provides a sensor assembly positioning tool. It can solve the problem of difficult alignment.

[0006] The technical scheme adopted by the utility model to solve its problem is:

[0007] A sensor assembly positioning tool, comprising: a roof cover plate, the roof cover plate is provided with an assembly position, the assembly position is provided with a first positioning structure and a first assembly hole; a sensor module, the sensor module comprises a sensor and a sensor mounting rack, the sensor is assembled on the sensor mounting rack, the sensor mounting rack is provided with a second positioning structure and a second assembly hole, the first positioning structure and the second positioning structure are clamped and positioned; fastener, the fastener is connected through the second assembly hole and the first assembly hole.

[0008] By adopting the above scheme, through the cooperation of the assembly position on the roof cover plate and the mounting frame of the sensor module, the clamping positioning of the first positioning structure and the second positioning structure can adapt to different curved surfaces and angles of the vehicle body frame, without the need for the operator to perform complex alignment operations; the clamping design of the first positioning structure and the second positioning structure can ensure accurate positioning of the sensor module during installation, avoiding visual errors and inaccurate alignment caused by improper operation. At the same time, the fastener is connected by being inserted through the second assembly hole and the first assembly hole, further enhancing the stability and precision of the installation.

[0009] Further, the assembly position comprises: a stop edge provided at one end of the assembly position; and an inclined surface inclined downward toward the stop edge, one end of the sensor mounting frame abutting against the stop edge, the stop edge providing a bearing force of gravity for the sensor mounting frame.

[0010] By adopting the above scheme, the provision of the stop edge provides a clear and stable support point for the sensor mounting frame. When one end of the sensor mounting frame abuts against the stop edge, the stop edge can effectively bear the sensor mounting frame and the sensor thereon, preventing displacement or falling due to gravity during installation, and making alignment more accurate after abutment, which can achieve the alignment effect by only translating.

[0011] Further, among the second positioning structure and the first positioning structure, one is an outwardly protruding elastic lug structure, and the other is an inwardly recessed clamping groove.

[0012] By adopting the above scheme, the cooperation of the elastic lug structure and the clamping groove forms a tight and reliable positioning mechanism. When the elastic lug structure on the sensor mounting frame is inserted into the clamping groove on the roof cover plate, the interaction between the two can ensure accurate alignment of the sensor mounting frame at the predetermined position. At the same time, since the elastic lug structure has a certain elasticity, it can adapt to small errors during assembly to some extent, thereby further improving the stability and accuracy of positioning; the design of the elastic lug structure and the clamping groove makes the connection between the sensor mounting frame and the roof cover plate more convenient and fast. The operator only needs to align the elastic lug structure on the sensor mounting frame with the clamping groove on the roof cover plate, and then gently push it to complete the installation. Similarly, the disassembly process also becomes easier.

[0013] Further, the elastic lug structure is inserted through the sensor mounting frame and partially extends into the clamping groove.

[0014] By adopting the above scheme, the tight contact between the sensor mounting frame and the roof cover plate is ensured.

[0015] Further, the elastic protrusion structure comprises a positioning seat, one end of the positioning seat is provided with an operation part, and the other end is provided with a cylindrical groove; a positioning piece is limited in the cylindrical groove, one end of the positioning piece is provided with a protrusion protruding from the cylindrical groove; and an elastic piece is arranged in the cylindrical groove and used for abutting against the other end of the positioning piece.

[0016] By adopting the above scheme, the combination design of the positioning seat and the positioning piece makes the elastic protrusion structure maintain high stability and accuracy during assembly. The positioning seat serves as a support structure to ensure the position stability of the positioning piece during assembly. By adjusting the rigidity and pre-tightening force of the elastic piece, the positioning performance can be further optimized; and the operation part is arranged to enable the operator to conveniently control the assembly and disassembly process of the elastic protrusion structure.

[0017] Further, the operation part is one of a slot, a cross slot, a mill-shaped slot and a hexagonal slot.

[0018] By adopting the above scheme, not only the assembly process is simplified, but also the assembly efficiency is improved, the adaptability of the assembly environment is enhanced, the durability and reliability are improved, and the safety risk is reduced.

[0019] Further, the protrusion and the positioning piece are integrally formed.

[0020] By adopting the above scheme, the assembly error and looseness between the two are avoided. This design makes the elastic protrusion structure maintain higher integrity and stability during assembly, thereby improving the positioning accuracy and reliability.

[0021] Further, one end of the cylindrical groove away from the operation part is provided with a clamping edge for clamping the positioning piece.

[0022] By adopting the above scheme, the assembly process is simplified, the adaptability is enhanced, the durability is improved, and the safety risk is reduced.

[0023] Further, an outer thread is arranged on the outer surface of the positioning seat, and the positioning seat is threadedly connected with the sensor mounting rack.

[0024] By adopting the above scheme, the threaded connection is a very stable connection mode, which can provide strong pulling force and pressure bearing capacity, and can adapt to the requirements of different vehicle models and sensor types for positioning accuracy.

[0025] Further, an adjusting device is arranged between the sensor and the sensor mounting rack.

[0026] By adopting the above scheme, the height adjusting device allows the operator to adjust the installation height of the sensor according to actual needs. This is particularly important for application scenarios that require precise control of the distance between the sensor and the object to be measured. In different working environments and vehicle types, the installation position of the sensor may be subject to various limitations. The height adjusting device can help the operator overcome these limitations and ensure that the sensor can be accurately installed to the predetermined position.

[0027] In summary, the sensor assembly positioning tool provided by the present application has the following technical effects:

[0028] 1. Simplify the installation process and improve efficiency: By cooperating between the assembly position on the roof cover plate and the mounting bracket of the sensor module, especially by using the clamping positioning of the first positioning structure and the second positioning structure, the installation process is greatly simplified. The operator no longer needs to perform complex alignment operations, but only needs to align and clamp the sensor module with the assembly position on the roof cover plate, thereby significantly improving the installation efficiency;

[0029] 2. Improve installation accuracy and ensure performance: The clamping design of the first positioning structure and the second positioning structure ensures accurate positioning of the sensor module during installation.

At the same time, the fastener 4 is connected through the second assembly hole 221 and the first assembly hole 112, further enhancing the stability and accuracy of the installation.

[0043] In some embodiments, the assembly site 11 on the roof cover plate 1 includes a stop edge 113 and an inclined surface 114. The stop edge 113 is located at one end of the assembly site 11, providing a bearing force for the sensor mounting bracket 22.
