Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle application technology, and in particular to a new energy vehicle engine operation and coupling positioning detection and adjustment structure. Background Technology

[0002] In the production and assembly process of new energy vehicles, the operation and mounting of the engine (such as core components like drive motors and reducers) and the frame is a key process that determines the overall power performance and driving safety of the vehicle. Whether the engine and frame are accurately mounted depends on a dedicated testing structure for judgment.

[0003] The existing testing structures have significant shortcomings in their positioning and testing function design. On the one hand, the vehicle frame lacks a stable positioning constraint mechanism during testing, relying solely on simple support blocks for placement. This makes it susceptible to vibrations in the assembly workshop and slight swaying during hoisting operations, causing the vehicle frame to deviate from the testing benchmark. Consequently, the testing data becomes inaccurate, affecting the accurate judgment of the vehicle's mounting position. On the other hand, the testing components are typically fixed directly to the testing fixture, making it impossible to move and adjust them according to different testing points on the vehicle body. This makes it difficult to fully cover testing needs, creating blind spots and increasing the risk of malfunctions after assembly. Therefore, this utility model proposes a vehicle mounting position detection and adjustment structure for new energy vehicles. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mechanism for detecting and adjusting the engine engagement position of a new energy vehicle, which aims to solve the technical problems existing in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a new energy vehicle engine mounting position detection and adjustment structure is provided, including a base plate, wherein the top of the base plate is symmetrically bolted with a receiving seat near the end face for adjusting the distance on the base plate to adapt to the width of the vehicle frame. Positioning components are fixedly connected to the top of both of the bearing seats near the end face to achieve positioning and fixation of the vehicle frame; The top of the receiving seat is movably connected to a detection component, and the detection component can slide and adjust between two positioning components simultaneously on the top of the receiving seat to achieve laser detection operation on different vehicle frames.

[0006] The present invention is further configured such that: multiple mounting holes are provided near the corners of the substrate, and connection holes for adjustment and installation are provided at the bottom corners of the two receiving seats.

[0007] Through the above technical solution, multiple mounting holes at the corners of the substrate and the connecting holes at the bottom of the support form multiple sets of matching combinations. By selecting mounting holes and connecting holes at different positions for bolt connection, the relative distance between the two supports on the substrate can be flexibly adjusted, thereby adapting to new energy vehicle frames of different models and widths. There is no need to replace the overall testing tooling, which improves the versatility of the equipment.

[0008] The present invention is further configured such that: the receiving seat includes a connecting plate bolted to the base plate, and support columns are symmetrically fixedly connected to the top of the connecting plate near the end face. A crossbeam is fixedly connected to the top of the two support columns, and a sliding groove is provided on the top of the crossbeam, and the detection component is slidably connected to the sliding groove.

[0009] Through the above technical solution, the connecting plate serves as the connecting carrier between the receiving seat and the base plate, ensuring connection stability; the support column provides vertical support to the crossbeam, ensuring that the crossbeam and the frame mounting area are at the same height, avoiding interference with other components of the frame during inspection; the groove at the top of the crossbeam provides a linear sliding track for the inspection component, ensuring that the inspection component can move stably along the width direction of the frame, providing a structural foundation for multi-point inspection.

[0010] The present invention is further configured such that: the positioning component includes a positioning column, the top of the positioning column is provided with a stepped settling groove, the interior of the stepped settling groove is provided with a spring, and the spring is wrapped around a stepped top block.

[0011] Through the above technical solution, the positioning column provides a fixed support foundation for the positioning component; the stepped structure of the stepped settling groove is adapted to the stepped shape of the stepped top block, which not only restricts the radial displacement of the stepped top block, but also provides guidance for its axial movement; the spring is wrapped around the outside of the stepped top block, which can absorb the impact force when the frame is placed through its own elastic deformation, and at the same time provide a continuous upward pressing force for the stepped top block, ensuring that the frame and the positioning component fit tightly together.

[0012] The present invention is further configured such that: the top block of the step is slidably connected to the inner wall of the step settling trough, and simultaneously abuts against the top of the spring.

[0013] Through the above technical solution, the sliding fit between the top block of the ladder and the inner wall of the ladder settling groove enables the stable lifting and lowering of the top block; when the frame is placed on the positioning component, the weight of the frame presses the top block of the ladder downward to compress the spring, and the spring generates a reverse elastic force, pushing the top block of the ladder to tightly abut against the bottom of the frame, forming "adaptive elastic positioning", which not only adapts to the thickness difference of different parts of the electric vehicle frame, but also avoids frame damage caused by rigid positioning, while improving positioning stability and reducing detection errors.

[0014] The present invention is further configured such that: the detection component includes a laser rangefinder sensor, the bottom of the laser rangefinder sensor is fixedly connected to a slide, and a locking bolt is provided through the side wall of the slide and passes through the slide groove.

[0015] The above technical solution uses Banner Q4X series rugged laser rangefinders as the core detection element. By emitting a laser beam, it can accurately measure the distance to the mounting point on the vehicle frame and determine whether the device is properly mounted. The carriage provides a mounting carrier for the sensor, and its cooperation with the slide rail enables the sensor to move and adjust along the crossbeam to meet the needs of different detection points. After the sensor moves to the target position, the locking bolts are tightened, and the carriage is fixed by the friction between the bolts and the inner wall of the slide rail, preventing the sensor from shifting during the detection process and ensuring the accuracy of the detection data.

[0016] The present invention is further configured such that: a limiting groove is provided on the side wall of the slide, and a locking bolt passes through the limiting groove and is slidably connected to the inner wall of the limiting groove.

[0017] Through the above technical solution, the limiting groove constrains the sliding trajectory of the locking bolt, preventing the bolt from radially deviating during the sliding process, thereby ensuring that the carriage and the laser rangefinder always move in the set direction; at the same time, the cooperation between the limiting groove and the locking bolt can share the weight of the carriage, reduce the frictional wear between the carriage and the bottom of the groove, extend the service life of the equipment, and further improve the stability and accuracy of the movement adjustment of the detection components.

[0018] The beneficial effects of this utility model are as follows: 1. The new utility model proposes a new energy vehicle engine mounting position detection and adjustment structure, which can be adapted to new energy vehicle frames of different widths by combining the mounting holes of the base plate and the connecting holes of the receiving seat, as well as the sliding adjustment of the detection components, without the need to replace special tooling, thus reducing production and maintenance costs. 2. The new utility model proposes a new energy vehicle engine coupling positioning detection and adjustment structure, which achieves adaptive elastic positioning of the vehicle frame through the elastic stepped top block structure of the positioning component, thereby avoiding damage to the vehicle frame, ensuring stable positioning, and reducing detection errors caused by positioning offset. 3. The new utility model proposes a new energy vehicle mounting position detection and adjustment structure that can move flexibly and lock along the slide groove through a laser rangefinder sensor, which can fully cover multiple detection points in the vehicle frame mounting area, with high detection accuracy and high efficiency, meeting the high-efficiency production needs of new energy vehicle assembly lines. 4. The new energy vehicle engine mounting position detection and adjustment structure proposed in this utility model improves the overall structural stability, reduces component wear, and extends equipment service life through the combination of the support column and crossbeam of the bearing seat, and the cooperation of the limiting groove and locking bolt.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figure 1 As shown, a new energy vehicle's vehicle mounting and positioning detection and adjustment structure includes a base plate 1. The top of the base plate 1 is symmetrically bolted with receiving seats 2 near the end face for adjusting the distance between them to fit the vehicle frame width. Multiple mounting holes are provided near the corners of the base plate 1, and connecting holes for adjustment are provided at the bottom corners of the two receiving seats 2. The multiple mounting holes at the corners of the base plate 1 and the connecting holes at the bottom of the receiving seats 2 form multiple sets of matching combinations. By selecting different mounting holes and connecting holes for bolt connection, the relative distance between the two receiving seats 2 on the base plate 1 can be flexibly adjusted, thus adapting to new energy vehicle frames of different models and widths. This eliminates the need to replace the overall detection fixture, improving the equipment's versatility.

[0023] like Figure 2As shown, the receiving seat 2 includes a connecting plate 21 bolted to the base plate 1. Support columns 22 are symmetrically fixed to the top of the connecting plate 21 near its end face. A crossbeam 23 is fixedly connected to the top of the two support columns 22. A groove 24 is provided on the top of the crossbeam 23, and the detection component 4 is slidably connected to the groove 24. The connecting plate 21 serves as the connection carrier between the receiving seat 2 and the base plate 1, ensuring connection stability. The support columns 22 provide vertical support to the crossbeam 23, ensuring that the crossbeam 23 maintains a suitable height with the frame mounting area, preventing interference with other components of the frame during detection. The groove 24 on the top of the crossbeam 23 provides a linear sliding track for the detection component 4, ensuring that the detection component 4 can move stably along the width direction of the frame, providing a structural foundation for multi-point detection. like Figure 2 and Figure 3 As shown, positioning components 3 are fixedly connected to the top of both receiving seats 2 near their end faces to achieve positioning and fixation of the frame. The positioning component 3 includes a positioning post 31, with a stepped settling groove 32 at its top. A spring 33 is installed inside the stepped settling groove 32, and the spring 33 wraps around a stepped top block 34. The positioning post 31 provides a fixed support foundation for the positioning component 3. The stepped structure of the stepped settling groove 32 matches the stepped shape of the stepped top block 34, limiting the radial offset of the stepped top block 34 and providing guidance for its axial movement. The spring 33, wrapped around the outside of the stepped top block 34, can absorb the impact force when the frame is placed through its own elastic deformation, while simultaneously providing support for the stepped top block 34. The step top block 34 provides a continuous upward clamping force to ensure that the frame and the positioning component 3 fit tightly together. The step top block 34 is slidably connected to the inner wall of the step settling groove 32 and abuts against the top of the spring 33. The sliding cooperation between the step top block 34 and the inner wall of the step settling groove 32 realizes the stable lifting and lowering of the top block. When the frame is placed on the positioning component 3, the weight of the frame presses the step top block 34 downward to compress the spring 33. The spring 33 generates a reverse elastic force, pushing the step top block 34 to fit tightly against the bottom of the frame, forming "adaptive elastic positioning". This not only adapts to the thickness difference of different parts of the electric vehicle frame, but also avoids frame damage caused by rigid positioning, while improving positioning stability and reducing detection errors.

[0024] like Figure 2As shown, a detection component 4 is movably connected to the top of the receiving seat 2, and the detection component 4 can slide and adjust between two positioning components 3 simultaneously on the top of the receiving seat 2 to realize laser detection operation on different frames. The detection component 4 includes a laser rangefinder sensor 41, and a slide 42 is fixedly connected to the bottom of the laser rangefinder sensor 41. A locking bolt 43 is provided through the side wall of the slide 42, and the locking bolt 43 passes through the slide groove 24. The Banner Q4X series rugged laser rangefinder sensor 41 is used as the core detection element. It can accurately measure the distance to the mounting part of the frame by emitting a laser beam to determine whether the body is mounted in place. The slide 42 provides a mounting carrier for the sensor. Its cooperation with the slide groove 24 realizes the movement and adjustment of the sensor along the crossbeam 23 to meet the needs of different detection points. When the sensor moves to the target position, the locking bolt 43 is tightened. The slide 42 is fixed by the friction between the bolt and the inner wall of the slide groove 24 to prevent the sensor from shifting during the detection process and ensure the accuracy of the detection data. The side wall of the slide 24 has a limiting groove 25, and the locking bolt 43 passes through the limiting groove 25 and is slidably connected to the inner wall of the limiting groove 25. The limiting groove 25 constrains the sliding trajectory of the locking bolt 43, preventing the bolt from radially deviating during sliding, thereby ensuring that the slide 42 and the laser rangefinder 41 always move in the set direction. At the same time, the cooperation between the limiting groove 25 and the locking bolt 43 can share the weight of the slide 42, reduce the frictional wear between the slide 42 and the bottom of the slide 24, extend the service life of the equipment, and further improve the stability and accuracy of the movement adjustment of the detection component 4.

[0025] In use, this invention first utilizes multiple sets of mounting holes at the corners of the base plate 1, which are then bolted to the connecting holes at the bottom of the support 2. By selecting different combinations of mounting holes and connecting holes, the relative distance between the two support 2s on the base plate 1 is adjusted to match the width of the frame to be tested. When the frame is lowered to the top of the support 2, the bottom of the frame presses against the step top block 34 in the step settling groove 32 of the positioning post 31 in the positioning assembly 3. This causes the step top block 34 to slide down along the inner wall of the step settling groove 32 and compress the spring 33. The reverse elastic force generated by the spring 33 pushes the step top block 34 tightly against the bottom of the frame, achieving adaptive and stable positioning of the frame. Then, the inspection is released. The locking bolt 43 on the side wall of the slide 42 in the measuring component 4 slides along the slide groove 24 on the top of the crossbeam 23 of the receiving seat 2 (while relying on the guiding constraint of the locking bolt 43 by the limiting groove 25 on the side wall of the slide groove 24). The laser range sensor 41, which is fixedly connected to the slide 42, is moved to the target detection point of the frame machine running hanger. Then the locking bolt 43 is tightened to fix the position of the slide 42. The laser range sensor 41 measures the distance between itself and the frame mounting part by emitting a laser beam. Based on the comparison between the measured distance and the preset "positioning distance value", it is determined whether the machine body is mounted in place. Finally, the entire process of adaptation, adjustment, stable positioning and accurate detection of different specifications of frame machine running hangers is completed.
