Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories installation, in particular to a positioning device for an automobile sensor rack. Background Art

[0002] The automotive production process requires the use of a variety of different sensor types. Each sensor, while performing the same function, can vary in appearance. Therefore, a sensor rack is required as a unified assembly plate, upon which the sensors are mounted, to improve efficiency and overall stability. Currently, automotive sensor racks require a positioning device during installation and assembly to ensure stable mounting at various workstations.

[0003] For example, patent application number CN202220652608.2 discloses a positioning device for an automobile sensor rack, comprising a mounting base, a set of spring telescopic rods fixedly connected to the middle of each of the two sides of the top wall of the mounting base, mounting holes are provided between the upper and lower side walls at the four corners of the mounting base, and the overall positioning device is convenient for installation and arrangement at the station to be installed, and a scale is fixedly installed in the middle of the rear side of the top wall of the mounting base. The utility model is provided with a good automobile sensor rack installation and adjustment positioning structure. When the automobile sensor rack is actually positioned and installed, two elastic clamping blocks are provided to achieve clamping and fixing of the automobile sensor rack to be installed. The automobile sensor rack is easy to install and disassemble, and the overall automobile sensor rack clamping and fixing structure is a sliding structure design. At the same time, a corresponding scale positioning structure is provided, which can quickly and accurately perform subsequent positioning and installation work.

[0004] The existing technology uses a base plate, a scale and an adjustable positioning structure to enable the sensor rack to be positioned and installed more accurately, but there are still certain shortcomings in the overall use process: the existing technology uses a rotatable elastic clamp to clamp and fix the sensor rack. Although it can ensure that the sensor rack can slide downward smoothly, it lacks a corresponding limiting structure setting. When the two elastic clamps rotate, the sensor rack is prone to slipping and shaking, making it impossible for the rack to be accurately and stably pressed into the specified hole, affecting production efficiency. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a positioning device for an automotive sensor rack. By providing a non-slip, roughened spring plate on the conical surface of the conical rotating block, and coordinating the provision of an inclined plate and a roughened pressure plate at the bottom of the connecting plate, the utility model solves the prior art problem of the sensor rack being prone to slippage and deviation when pressed downward. This allows the sensor rack to be stably pressed into various mounting holes, improving installation accuracy.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a positioning device for an automotive sensor sheet rack, comprising a base plate with a rectangular opening in the middle, fixed plates provided on both sides of the upper end surface of the base plate, a drive rack slidably provided between the two fixed plates, a rotating base plate provided on both side end surfaces of the bottom of the drive rack, torsion spring seats provided on two opposing end surfaces of the rotating base plates, a conical rotating block with one end having a conical angle rotatably provided between the two torsion spring seats, a connecting plate slidably provided between the two conical rotating blocks, two outwardly inclined inclined plates provided on both sides of the bottom of the connecting plate, roughened pressure plates provided on the bottom end surfaces of the two inclined plates, and a plurality of elastic bands connected between the two roughened pressure plates. The provision of the roughened pressure plates and the conical rotating blocks prevents the sheet rack from deflecting and slipping when pressed downward.

[0007] Preferably, slide bars are slidably mounted at the four corners of the upper end face of the drive frame, with the bottom ends of the multiple slide bars extending out of the end face of the drive frame and connected to a connecting plate, and the top ends of the slide bars connected to a pressure plate, with springs disposed on the outside of the slide bars between the pressure plate and the drive frame. The arrangement of the slide bars and springs allows the connecting plate to smoothly complete the upward and downward pressing movement.

[0008] Preferably, a rough spring plate made of elastic material and curved outwards is provided on the upper conical surface of the conical rotating block. The provision of the rough spring plate can effectively prevent the sheet rack from slipping and deviating to the sides.

[0009] Preferably, a rotating shaft is provided within the conical rotating block, with both ends of the rotating shaft rotatably connected to a torsion spring seat, and a torsion spring is connected to one end of the rotating shaft within the torsion spring seat. The torsion spring ensures that the conical rotating block automatically returns to its original position when external pressure is lost, and also provides a certain amount of supporting pressure when pressed downward, preventing the conical rotating block from rapidly turning over.

[0010] Preferably, a plurality of hard sheets are provided on the bottom end surface of each elastic band. The provision of the hard sheets can improve the anti-slip effect on the sheet rack.

[0011] Preferably, a plurality of hard pads are evenly embedded in the end surface of the rough surface pressure plate along a straight line. The provision of the hard pads can provide multiple support and anti-slip points on the top of the sheet rack.

[0012] Preferably, a transmission screw is provided on the exterior of the drive frame, connected to the two fixed plates. A drive motor is provided on one side of the transmission screw on the end surface of the fixed plate, and the output end of the drive motor is connected to the end surface of the transmission screw. The provision of the transmission screw ensures the movement efficiency and positioning accuracy of the drive frame.

[0013] In summary, compared with the prior art, the beneficial effects of this solution are:

[0014] The utility model provides a non-slip rough spring plate on the conical surface of the conical rotating block for limiting on both sides, and provides an inclined plate and a rough pressure plate at the bottom of the connecting plate that is pressed downward, so that when the sheet frame is pressed downward for installation, both sides and the top have a certain non-slip limiting treatment, which solves the problem that the sensor sheet frame is prone to slipping and deflecting during the downward pressing process, so that the sensor sheet frame can be stably pressed into various installation holes, thereby improving the installation accuracy.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1:

[0025] refer to Figure 1-9A positioning device for an automobile sensor rack includes a base plate 31 with a rectangular opening in the middle, fixed plates 32 on both sides of the upper end surface of the base plate 31, a driving frame 33 slidingly arranged between the two fixed plates 32, a rotating base plate 45 on both side end surfaces of the bottom of the driving frame 33, and a torsion spring seat 43 on the end surfaces of the two opposite rotating base plates 45. A conical rotating block 44 with one end having a conical angle is rotatably arranged between the two torsion spring seats 43. The cone angles of the two conical rotating blocks 44 are close to each other, so that the cone surfaces of the two conical rotating blocks 44 are trumpet-shaped. At this time, when the sensor rack is placed on the cone surfaces of the two conical rotating blocks 44, it will slide downward in the center due to the cone surfaces.

[0026] A connecting plate 38 is slidingly arranged between the two conical rotating blocks 44. Two outward-inclined inclined plates 39 are arranged on both sides of the bottom of the connecting plate 38. The two inclined plates 39 are made of elastic metal material and have a certain elastic deformation ability. A rough surface pressure plate 42 is arranged on the bottom end surface of the two inclined plates 39. A plurality of elastic bands 40 are connected between the two rough surface pressure plates 42 for connecting and supporting the inclined plates 39.

[0027] Specifically, when the sensor rack needs to be installed, the staff places the substrate 31 on the installation station. There are fixing holes at the four corners of the upper end surface of the substrate 31. Bolts can be screwed into the outside of the station through the fixing holes to fix the substrate 31.

[0028] After the base plate 31 is fixed, the staff can drive the driving frame 33 to move on the two fixed plates 32. The bottom of the driving frame 33 is frame-shaped as a whole, and the bottom is open, so that the sensor rack can be placed and installed. The staff can place the sensor rack on the conical surfaces of the two conical rotating blocks 44. The cone angles of the two conical rotating blocks 44 are close to each other, so that the conical surfaces of the two conical rotating blocks 44 are flared. At this time, when the sensor rack is placed on the conical surfaces of the two conical rotating blocks 44, it will slide downward in the center due to the conical surfaces. In this solution, the two ends of the conical rotating blocks 44 are rotatably connected through the torsion spring seat 43;

[0029] When the material on the sensor rack is placed and the driving frame 33 moves to the designated position, the staff can push the connecting plate 38 to move downward, thereby pushing the two inclined plates 39 at the bottom of the connecting plate 38 to move downward. The two inclined plates 39 are made of elastic metal material and have a certain elastic deformation ability. When the rack is pressed into the hole and there is resistance, they bend and deform to form a buffer space between the rack and the connecting plate 38 to avoid instant damage to the rack, so that the staff has reaction time. The two inclined plates 39 are inclined in opposite directions, so that the two inclined plates 39 form an eight-shaped shape, so that the contact area between the rough surface pressure plate 42 on the bottom end face and the sensor rack is effectively increased. The bottom end face of the rough surface pressure plate 42 is provided with a plurality of V-shaped anti-slip grooves, so that the rough surface pressure plate 42 contacts the top of the sensor rack and presses downward, and the rack will not shake at will, so that the rack can be stably pressed into the designated hole.

[0030] The elastic band 40 disposed between the two rough surface pressure plates 42 is used to connect and support the inclined plate 39. On the one hand, it prevents the inclined plate 39 from changing too much in elasticity and ensures a certain strength. On the other hand, it fills the area between the two rough surface pressure plates 42, increases the contact area, and prevents the sensor frame from sliding.

[0031] When the sheet rack continues to be pressed down, the two conical rotating blocks 44 will slowly flip downward, allowing the sheet rack to be pressed in smoothly and forming a limit on both sides of the sheet armor. When the pressing is completed, the connecting plate 38 returns to its position upward, and the top of the conical rotating block 44 loses pressure. At this time, the conical rotating block 44 will rotate back to its position under the torsion spring seat 43.

[0032] refer to Figure 5 A rough spring plate 46 made of elastic material and curved outward is provided on the upper conical surface of the conical rotating block 44 .

[0033] Specifically, the rough spring plate 46 is made of elastic material, is bent outward as a whole, and is provided with multiple anti-slip ridges on the outer surface, which are arranged on the conical surface of the conical rotating block 44, which can increase the contact friction on both sides of the sensor frame, so that the sensor frame will not shake at will when no pressure is applied, and will not slip when the whole is pressed downward, thereby improving the stability and accuracy of the sensor frame when pressed in.

[0034] refer to Figure 8-9 A rotating shaft 47 is provided in the conical rotating block 44 , and both ends of the rotating shaft 47 are rotatably connected to the torsion spring seat 43 . One end of the rotating shaft 47 in the torsion spring seat 43 is connected to a torsion spring 49 .

[0035] Specifically, when the conical rotating block 44 rotates, the conical rotating block 44 will drive the rotating shaft 47 to rotate, so that the torsion spring 49 at one end of the rotating shaft 47 is elastically stressed. When the pressure outside the conical rotating block 44 is lost, the torsion spring 49 will release the pressure, so that the rotating shaft 47 and the conical rotating block 44 can be quickly flipped back to their original positions, so that the device can complete the subsequent installation process.

[0036] refer to Figure 6 , a plurality of hard sheets 41 are provided on the bottom end surface of each elastic band 40 .

[0037] Specifically, the hard sheet 41 is made of anti-slip material. When the elastic band 40 is pressed on the sensor frame, the end surface of the hard sheet 41 will also contact the sensor frame, thereby improving the stability of the sensor during pressing and reducing sliding vibration.

[0038] refer to Figure 1 、 5 Slide rods 36 are slidably provided at the four corners of the upper end surface of the driving frame 33. The bottom ends of the multiple slide rods 36 extend out of the end surface of the driving frame 33 and are connected to a connecting plate 38. The top ends of the slide rods 36 are connected to a pressure plate 34. A spring 35 is provided on the outside of the slide rods 36 between the pressure plate 34 and the driving frame 33.

[0039] Specifically, a handle is provided between the two pressure plates 34. When the connecting plate 38 needs to be pressed downward, the staff grabs the handle and presses it downward. The handle will push the two pressure plates 34 and the two slide bars 36 at the bottom of the pressure plates 34 to slide downward. The slide bars 36 will drive the connecting plates 38 to slide downward, so that the sensor sheet frame under the connecting plates 38 can be pressed into the designated hole position. During this process, the spring 35 will be under pressure. When the staff releases the handle, the multiple springs 35 will release the pressure, causing the slide bars 36 and the pressure plate 34 to slide upward and return to their positions.

[0040] refer to Figure 7 A transmission screw 37 is provided on the outside of the drive frame 33 for transmission connection between the two fixed plates 32. A drive motor is provided on one side of the transmission screw 37 on the end surface of the fixed plate 32, and the output end of the drive motor is connected to the end surface of the transmission screw 37.

[0041] Specifically, a sliding rod is provided on one side of the transmission screw 37 between the two fixed plates 32, and transmission blocks and sliders are provided at both ends of the outside of the driving frame 33 to cooperate with the transmission screw 37 and the sliding rod, so that when the driving motor is started, the transmission screw 37 can stably drive the driving frame 33 to move accurately, thereby improving the positioning effect of the driving frame 33. Example 2:

[0042] On the basis of or different from the first embodiment, reference is made to Figure 6A plurality of hard pads 48 are evenly embedded in the end surface of the rough surface pressure plate 42 along a straight line direction.

[0043] Specifically, the outer end surface of the hard pad 48 is roughened, and the overall end surface slightly protrudes from the end surface of the rough pressure plate 42. When the rough pressure plate 42 forms a larger anti-slip contact zone, it can provide anti-slip enhancement treatment at multiple points, thereby improving the stability of the sensor frame during press-fit installation.

[0044] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0045] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.
