Description

Technical Field

[0001] This utility model relates to the field of vehicle collision testing technology, and in particular to a traction track. This utility model relates to a vehicle collision testing system equipped with the aforementioned traction track. Background Technology

[0002] The traction system is a crucial component of an automotive crash test platform. Within this system, a steel cable typically connects the traction trolley. The cable passes through a hollow section in the middle of the traction track, winds around a transmission pulley system, and ultimately pulls the vehicle via a traction motor to complete the crash test. Therefore, the straightness and flatness of the traction track significantly impact the overall accuracy of the crash test. The straightness and flatness of the track are primarily determined by the embedded fixture components beneath it.

[0003] In traditional vehicle crash testing, collision speeds are generally limited to around 80 km / h. However, with the increasing sophistication of vehicle powertrains, crash tests now demand higher collision speeds, requiring speeds exceeding 100 km / h. This change presents challenges to traction systems, placing higher demands on the structural strength, rigidity, and precision of the traction rails. Existing traction rails suffer from insufficient strength in their embedded tooling components, resulting in inadequate tension on the rails. Prolonged high-speed use can easily cause deformation or the traction rails to be pulled out of their embedded parts, making it difficult to meet the demands of frequent high-speed crash tests. Utility Model Content

[0004] In view of this, the present invention aims to provide a traction track that can improve its overall structural strength.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A traction rail for vehicle crash testing includes a rail assembly and a pre-embedded tooling assembly for mounting the rail assembly.

The embedded tooling assembly consists of multiple components spaced apart along the length of the track assembly, and a reinforcing component is provided between at least some of the adjacent embedded tooling assemblies.

[0008] The reinforcing component, the adjacent embedded tooling component, and the track component are all connected.

[0009] Furthermore, the reinforcing component includes a first reinforcing member connected between two adjacent pre-embedded tooling components, and a second reinforcing member connected between the first reinforcing member and the track component.

[0010] Furthermore, the first reinforcing member and the two adjacent pre-embedded tooling assemblies are detachably connected; and / or, the second reinforcing member is detachably connected to the first reinforcing member and the track assembly.

[0014] Furthermore, the track assembly includes a track body, and a first connecting seat and a second connecting seat disposed on the track body; both ends of the track body are provided with the first connecting seat, and each of the first connecting seats is connected to the pre-embedded tooling assembly located at the end of the track body; the second connecting seat is located between the two first connecting seats, and the second connecting seat is connected to the reinforcing assembly.

[0015] Furthermore, the track body is provided with at least one third connecting seat, and the number of the pre-embedded tooling components matches the sum of the number of the third connecting seats and the number of the first connecting seats; and / or, the track body is provided with a sensor mounting box, each side wall of the sensor mounting box is provided with a through hole, and each through hole may selectively be provided with a plug.

[0016] Furthermore, the track assembly consists of multiple track bodies connected end to end in sequence; each track body is provided with a positioning groove and a positioning end face located at the opening of the positioning groove; the positioning groove and the positioning end face are used to match and dock with the tooling to position the relative position between two adjacent track bodies.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] (1) The traction rail described in this utility model can distribute the rail load to multiple support points through the set rail components and multiple pre-embedded tooling components arranged at intervals, so as to avoid the rail deformation caused by excessive force at a single point and improve the stability of the rail in vehicle collision test; the adjustment structure in the pre-embedded tooling components can adjust the height and horizontal position of the rail components, which can ensure the installation accuracy of the rail; a reinforcing component is set between two adjacent pre-embedded tooling components, so that the reinforcing component is connected to the adjacent pre-embedded tooling components and the rail components, thereby forming an integrated support structure for the rail components. This structural design can improve the overall structural strength of the traction rail, enhance the overall rigidity of the traction rail, reduce the risk of rail components being deformed or pulled out of the pre-embedded parts, and has a good use effect.

[0019] (2) The reinforcing component includes a first reinforcing member and a second reinforcing member, such that the first reinforcing member is connected to both of the two adjacent pre-embedded tooling components, and the second reinforcing member is connected to both the first reinforcing member and the track component. In this way, a spatial support structure is formed between the two adjacent pre-embedded tooling components, the track component, and the first and second reinforcing members, which can significantly improve the load-bearing capacity and deformation resistance of the track component, enhance the overall structural strength and overall rigidity of the traction track, and the setting of the second reinforcing member can also provide tension to the track component, so that the track component is subjected to more uniform force and has high strength, which can effectively prevent the track component from being pulled out of the pre-embedded part due to long-term high-speed use.

[0020] (3) The detachable connection design between the first reinforcing member and the embedded tooling assembly, and between the second reinforcing member and the first reinforcing member and the track assembly, facilitates the installation, disassembly and maintenance of the traction track system, and also facilitates transportation.

[0021] (4) The embedded tooling assembly adopts a combination structure of base and support frame. The base provides stable foundation support, and the support frame is used to support the track assembly. This design can improve the load-bearing capacity and stability of the embedded tooling assembly. The height position of the support frame can be adjusted through the first adjustment unit, which in turn can adjust the height position of the track assembly, which helps to ensure the levelness of the track assembly during installation. The reinforcing assembly is connected to the support frame in the two adjacent embedded tooling assemblies. The support frame is set to provide the installation foundation for the reinforcing assembly, so that the reinforcing assembly can more directly transfer the load to the embedded tooling assembly, thereby enhancing the structural strength and stability of the entire track system.

[0022] (5) Multiple sets of first adjustment units are arranged at intervals along the circumference of the base, which can provide stable support for the support frame and also realize multi-point adjustment of the height of the support frame. This helps to ensure the levelness of the support frame and prevent the support frame from tilting, thereby ensuring the installation accuracy of the track assembly. Each first adjustment unit includes a first screw and two first nuts. Existing standard parts can be used, which is low in cost. Moreover, with two first nuts, after adjusting the level position of the support frame with one first nut, the other first nut can be tightened. This way, the support frame can be kept in a stable position after the height is adjusted, which also helps to improve the stability of the connection between the support frame and the first adjustment unit.

[0023] (6) The second adjustment unit can push the side of the track assembly with the side pusher, which can adjust the position of the track assembly in the width direction, eliminate the lateral deviation of the track assembly during installation, and improve the straightness and centering of the track assembly; the third adjustment unit can push the bottom of the track assembly with the bottom pusher, which can further adjust the height position of the track assembly. The use of the third adjustment unit in conjunction with the first adjustment unit can realize two adjustments of the height of the track assembly, namely coarse adjustment and fine adjustment, so as to further ensure the levelness and installation accuracy of the track assembly; the fourth adjustment unit can adjust the position of the track assembly in the length direction, which can eliminate the deviation in the length direction during the installation of the track assembly and help improve the docking accuracy between two adjacent track assemblies.

[0024] (7) The track body is provided with a first connecting seat at both ends and a second connecting seat between the two first connecting seats, so that the first connecting seat is connected to the corresponding pre-embedded tooling component and the second connecting seat is connected to the reinforcing component. This can provide stable support for the track component and enhance the load-bearing capacity of the middle part of the track body, effectively resisting the bending stress generated by the track body during use. Moreover, compared with the track structure with burrs, this structure is also conducive to reducing the weight of the track and is conducive to lightweight design.

[0025] (8) At least one third connecting seat is provided on the track body, which can further increase the connection points between the track body and the pre-embedded tooling components, and further improve the stability of the track body support; the sensor mounting box provided on the track body provides installation space for the sensor and facilitates the feedback of position signals; the design of through holes and plugs on each side wall of the sensor mounting box facilitates the wiring and maintenance of the sensor, and at the same time, the appropriate through holes can be selected for wiring harness arrangement according to actual needs, and the unsuitable through holes can be sealed with plugs, thus improving the use effect of the sensor mounting box.

[0026] (9) The track assembly adopts a multi-segment design that is connected end to end in sequence. The number of track assemblies can be flexibly combined according to the test length requirements, and it is convenient to transport. The positioning end face and positioning groove on the adjacent track body cooperate with the docking tool to position the relative position between the two adjacent track bodies, effectively control the track docking error, and help ensure the overall accuracy of the traction track.

[0027] Another objective of this invention is to provide a vehicle collision testing system, wherein the vehicle collision testing system is provided with the traction track described above.

[0028] The vehicle collision testing system of this utility model, by adopting the above-mentioned traction rail, can ensure the installation accuracy of the rail components, improve the overall structural strength and rigidity of the traction rail, reduce the risk of rail components being deformed or pulled out of the pre-embedded structure, and thus improve the reliability of the vehicle collision testing system.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] Example 1

[0047] This embodiment relates to a traction rail used for vehicle collision testing, which can improve the overall structural strength of the traction rail while ensuring installation accuracy.

[0048] In terms of overall structure, refer to Figures 1 to 3 As shown, the traction track in this embodiment includes a track assembly 1 and a pre-embedded tooling assembly 2 for installing the track assembly 1.

[0049] The embedded tooling assembly 2 has an adjustment structure that can adjust the height and / or horizontal position of the track assembly 1. The embedded tooling assembly 2 consists of multiple components spaced apart along the length of the track assembly 1. A reinforcing assembly 3 is provided between at least some of the adjacent embedded tooling assemblies 2. The reinforcing assembly 3 is connected to the adjacent embedded tooling assembly 2 and the track assembly 1.

[0050] In this structure, the track component 1 and the multiple pre-embedded fixture components 2 arranged at intervals can distribute the track load to multiple support points, avoiding excessive stress at a single point that could cause track deformation and improving the track's stability during vehicle collision tests. The adjustment structure in the pre-embedded fixture components 2 can adjust the height and horizontal position of the track component 1, ensuring track installation accuracy.

[0051] At the same time, a reinforcing component 3 is set between two adjacent pre-embedded tooling components 2, so that the reinforcing component 3 is connected to the adjacent pre-embedded tooling components 2 and the track component 1, thereby forming an integrated support structure for the track component 1. This structural design can improve the overall structural strength of the traction track, enhance the overall rigidity of the traction track, and reduce the risk of the track component 1 being deformed or pulled out of the pre-embedded part.

[0052] Based on the above overview, in detail, an exemplary structure of the traction track in this embodiment is as follows: Figures 1 to 3As shown, the traction track includes a track assembly 1 and embedded tooling assemblies 2. Multiple embedded tooling assemblies 2 are arranged at intervals along the length of the track assembly 1, and these multiple embedded tooling assemblies 2 are used to support and install the track assembly 1. Reinforcing assemblies 3 are disposed between two adjacent embedded tooling assemblies 2, and the reinforcing assemblies 3 are connected to both adjacent embedded tooling assemblies 2 and the track assembly 1.

[0053] It should be noted that the embedded tooling components 2 can be arranged in pairs, or in three, four, or more pairs, spaced apart along the length of the track component 1. When the number is greater than two, the reinforcing components 3 can be placed only between some adjacent embedded tooling components 2. Alternatively, reinforcing components 3 can be placed between every two adjacent embedded tooling components 2. Preferably, in this embodiment, reinforcing components 3 are provided between every two adjacent embedded tooling components 2. This better improves the overall structural strength and rigidity of the traction track, reducing the risk of deformation or being pulled out of the embedded parts of the track component 1.

[0054] In a preferred embodiment, the reinforcing component 3 includes a first reinforcing member 31 connected between two adjacent pre-embedded tooling components 2, and a second reinforcing member 32 connected between the first reinforcing member 31 and the track component 1. The first reinforcing member 31 extends along the length direction of the track component 1, and the second reinforcing member 32 extends along a direction intersecting the length direction.

[0055] Specifically, refer to Figure 2 and Figure 3 As shown, the reinforcing component 3 includes a first reinforcing member 31 and a second reinforcing member 32. The first reinforcing member 31 extends along the length of the track component 1 and is connected to both adjacent pre-embedded tooling components 2. Preferably, in specific implementations, the first reinforcing member 31 is made of U-shaped steel, which is a standard component with a relatively simple structure and high strength. It can be understood that, in addition to U-shaped steel, the first reinforcing member 31 can also be made of a long strip of plate, an L-shaped plate, or a T-shaped plate; all of these are acceptable.

[0056] The second reinforcing member 32 extends along the intersecting directions of the length direction and is connected to both the first reinforcing member 31 and the track assembly 1. In a preferred embodiment, the second reinforcing member 32 includes a vertically arranged tie rod, that is, the tie rod is arranged perpendicular to the length direction of the track assembly 1, and the two ends of the tie rod are respectively connected to the first reinforcing member 31 (i.e., the U-shaped steel) and the track assembly 1.

[0057] Similarly, it can be understood here that the second reinforcing member 32, in addition to being a tie rod connected to both the U-shaped steel and the track assembly 1, can also be made of U-shaped steel, angle steel, or other structural forms. Furthermore, besides being arranged along the length of the track assembly 1, the tie rod can also be arranged at an angle, that is, at an angle to the track assembly 1 or the first reinforcing member 31; this is also acceptable.

[0058] In this embodiment, as a further preferred implementation, the reinforcing components 3 are multiple sets symmetrically arranged on both sides of the track assembly 1, and each set of reinforcing components includes a first reinforcing component 31 and a second reinforcing component 32. Referring again... Figure 2 and Figure 3 As shown, first reinforcing members 31 connecting two adjacent embedded tooling assemblies 2 are provided on both sides of the track assembly 1, and second reinforcing members 32 are also connected between each first reinforcing member 31 and the track assembly 1. That is, U-shaped steel and tie rods are provided on both sides of the track assembly 1. The two ends of the U-shaped steel on each side are connected to the two adjacent embedded tooling assemblies 2, and the two ends of each tie rod are connected to the U-shaped steel and the track assembly 1 on the same side. This arrangement improves the overall structural strength of the traction track while also ensuring the stress balance and installation stability of the track assembly 1.

[0059] In this embodiment, the reinforcing component 3 adopts a structure of first reinforcing member 31 and second reinforcing member 32, forming a spatial support structure between two adjacent pre-embedded tooling components 2, track component 1, and the first and second reinforcing members 31 and 32. This significantly improves the load-bearing capacity and deformation resistance of track component 1, enhancing the overall structural strength and rigidity of the traction track. Furthermore, the second reinforcing member 32 provides tensile force to track component 1, resulting in more uniform stress distribution and higher strength, effectively preventing track component 1 from being pulled out of the pre-embedded structure due to prolonged high-speed use.

[0060] In some feasible embodiments, preferably, the first reinforcing member 31 and the adjacent embedded tooling assembly 2 are detachably connected, and the second reinforcing member 32 is also detachably connected to the first reinforcing member 31 and the track assembly 1. This detachable connection design between the first reinforcing member 31 and the embedded tooling assembly 2, and between the second reinforcing member 32 and the first reinforcing member 31 and the track assembly 1, facilitates the installation, disassembly, and maintenance of the traction track system, and also facilitates transportation.

[0061] In this embodiment, the first reinforcing member 31, i.e., the U-shaped steel, is connected to the two adjacent embedded tooling components 2 by bolts. Specifically, each embedded tooling component 2 is provided with a mounting plate 2221 for installing the U-shaped steel. The mounting plate 2221 has a first connecting hole, and the U-shaped steel has a second connecting hole. The first and second connecting holes are preferably elongated holes, with the long axis of the first connecting hole along the width direction of the track component 1 and the long axis of the second connecting hole along the length direction of the track component 1. The U-shaped steel is bolted and fixed to the embedded tooling component 2 by connecting bolts 34 passing through the first and second connecting holes.

[0062] It is worth mentioning here that the first connecting hole and the second connecting hole are elongated holes extending in mutually perpendicular directions, which can compensate for the positional error between the first reinforcing member 31 and the two connected pre-embedded tooling components 2, making the installation of the first reinforcing member 31 more convenient.

[0063] In this embodiment, the second reinforcing member 32, i.e., the tie rod, is also screwed to the U-shaped steel and the track assembly 1. Specifically, the U-shaped steel has a third connecting hole, and the track assembly 1, i.e., the second connecting seat 12 described below, has a fourth connecting hole, and both ends of the tie rod have external threads. At this time, both ends of the tie rod pass through the third and fourth connecting holes respectively, and are screwed together with the external threads by fastening nuts 33, thus fixing the U-shaped steel and the tie rod, as well as the second connecting seat 12 in the track assembly 1, together. In specific implementation, fastening nuts 33 are provided on both sides of the U-shaped steel and both sides of the second connecting seat 12 to improve the reliability of the connection between the tie rod and the U-shaped steel, and between the tie rod and the track assembly 1.

[0064] It should be noted that the first reinforcing member 31 can also be welded to the two adjacent embedded tooling components 2, and the second reinforcing member 32 can also be welded to the first reinforcing member 31, i.e., the track assembly 1. In addition to the screw connection between the first reinforcing member 31 and the two adjacent embedded tooling components 2, and between the second reinforcing member 32 and the first reinforcing member 31 and the track assembly 1, other detachable connection methods such as plug-in or snap-fit ​​can also be used, as long as the connection strength between the first reinforcing member 31 and the two adjacent embedded tooling components 2, and between the second reinforcing member 32 and the first reinforcing member 31 and the track assembly 1 is ensured.

[0065] Reference Figure 4 and combined Figure 2 and Figure 3As shown, in this embodiment, each embedded tooling assembly 2 includes a base 21 and a support frame 22 mounted on the base 21. The embedded tooling assembly 2 adopts a combined structure of base 21 and support frame 22. The base 21 provides stable foundation support, and the support frame 22 is used to support the track assembly 1. This design can improve the load-bearing capacity and stability of the embedded tooling assembly 2.

[0066] In terms of specific structure, the base 21 includes a top plate 211 and a plurality of legs 212 supporting the top plate 211. The top plate 211 is provided with a base plate 210, and the support frame 22 is connected to the base plate 210. The arrangement of the base plate 210 can improve the support strength of the support frame 22 and also facilitate the arrangement of the first adjustment unit 10 described below. The plurality of legs 212 are arranged at intervals along the circumference of the top plate 211, and a reinforcing member is provided between two adjacent legs 212.

[0067] In a preferred embodiment, each support leg 212 is L-shaped and has a vertical rod 2121 and a horizontal rod 2122 connected together. The end of the vertical rod 2121 away from the horizontal rod 2122 is connected to the top plate 211, and the horizontal rod 2122 extends from the end of the vertical rod 2121 to the outside of the base 21. The reinforcing member is a reinforcing ring 2123 fitted on the multiple support legs 212. In a specific implementation, the reinforcing ring 2123 is formed by bending a rod-shaped material, and the reinforcing ring 2123 is welded to each vertical rod 2121.

[0068] In this embodiment, there are six support legs 212. It should be understood that the function of the support legs 212 is to provide stable support for the top plate 211. In addition to being L-shaped, the support legs 212 can also be other shapes. Furthermore, in addition to being six, the number of support legs 212 can also be three, four, or eight, etc., and this embodiment does not limit this.

[0069] Still refer to Figure 3 As shown, the structure of the support frame 22, in a preferred embodiment, includes a base plate 221 and a support plate 223 arranged at intervals, and a support body 222 connected between the base plate 221 and the support plate 223. The cross-section of the support body 222 is cross-shaped to provide good support stability. A mounting plate 2221 for installing the first reinforcing member 31 is also fixedly connected to the support body 222. In specific manufacturing, the support frame 22 can be formed by welding H-beams and plates, resulting in a relatively simple structure with high strength, and easy manufacturing.

[0070] In this embodiment, the adjustment structure in the embedded tooling assembly 2 can adjust the height and / or horizontal position of the track assembly 1. That is, the adjustment structure can adjust only the height of the track assembly 1, or only the horizontal position of the track assembly 1, or both the height and horizontal positions of the track assembly 1 can be adjusted. As a preferred embodiment, the adjustment structure in this embodiment can adjust both the height and horizontal positions of the track assembly 1.

[0071] As a preferred embodiment, the adjustment structure of this embodiment includes a first adjustment unit 10 connected between the base 21 and the support frame 22. The first adjustment unit 10 can adjust the height position of the support frame 22, that is, it can adjust the height position of the track assembly 1, which helps to ensure the levelness of the track assembly 1 during the installation process.

[0072] Specifically, in a preferred embodiment, the first adjustment unit 10 consists of multiple sets connecting the base 21 and the support frame 22, with these multiple sets of first adjustment units 10 arranged at intervals along the circumference of the base 21. In this way, by arranging multiple sets of first adjustment units 10 at intervals along the circumference of the base 21, the support frame 22 can be stably supported while also allowing for multi-point adjustment of the height of the support frame 22. This helps ensure the levelness of the support frame 22, prevents it from tilting, and thus helps ensure the installation accuracy of the track assembly 1.

[0073] Reference Figures 2 to 4 As shown, each first adjustment unit 10 includes a first screw 1001 vertically arranged on the base 21, and two first nuts 1002 screwed to the first screw 1001. One end of the first screw 1001 is connected to the base 21, and the other end of the first screw 1001 passes through the bottom plate 221 of the support frame 22. The two first nuts 1002 are placed on both sides of the bottom plate 221.

[0074] In specific implementation, the first screw 1001 is fixedly connected to the base plate 210, that is, one end of the first screw 1001 is welded and fixed to the base plate 210. The other end of the first screw 1001 passes through the base plate 221 in the support frame 22 and is fixed by two first nuts 1002. The base plate 210 can be fixed to the base 21 by screwing, welding, or a combination of screwing and welding.

[0075] To enhance the connection strength between the support frame 22 and the base 21, in this embodiment, reinforcing ribs 23 are also provided on the base 21 and the support frame 22 bracket. Specifically, the reinforcing ribs 23 are arranged vertically, and there are multiple reinforcing ribs 23 arranged along the circumference of the base plate 210. Each reinforcing rib 23 is welded and fixed together with the base plate 210 and the bottom plate 221.

[0076] Here, each first adjustment unit 10 includes a first screw 1001 and two first nuts 1002, which can be existing standard parts, resulting in low cost. Moreover, by configuring two first nuts 1002, after adjusting the horizontal position of the support frame 22 using one of the first nuts 1002, the other first nut 1002 can be used to tighten it. This ensures that the support frame 22 can be maintained in a stable position after the height is adjusted, and also helps to improve the stability of the connection between the support frame 22 and the first adjustment unit 10.

[0077] In this embodiment, the reinforcing component 3 is connected to the support frames 22 in the two adjacent embedded tooling components 2, and each support frame 22 is used to support the track component 1. The support frames 22 provide an installation foundation for the reinforcing component 3, enabling the reinforcing component 3 to transfer the load to the embedded tooling components 2 more directly, thereby enhancing the structural strength and stability of the entire track system. In specific implementation, the first reinforcing member 31 in the reinforcing component 3, i.e., the U-shaped steel, is screwed to the mounting plate 2221 on the support frame 22.

[0078] As a further preferred embodiment, the adjustment structure of this embodiment also includes a second adjustment unit 20 disposed on the support frame 22. The second adjustment unit 20 has a side pushing part that pushes the side of the track assembly 1. This side pushing part can adjust the position of the track assembly 1 in the width direction. In this way, the side pushing part can be used to push the side of the track assembly 1, thereby adjusting the position of the track assembly 1 in the width direction, eliminating lateral deviation of the track assembly 1 during installation, and improving the straightness and centering of the track assembly 1.

[0079] Specifically, the support frame 22 is provided with mounting blocks located on both sides of the track assembly 1. Each mounting block is provided with a second adjustment unit 20. Each second adjustment unit 20 includes a second screw 2001 screwed to the mounting block and a second nut 2002 screwed to the second screw 2001. The second screw 2001 is arranged horizontally along its axis, and the aforementioned side pushing part is formed by the end of the second screw 2001. By tightening or loosening the second screw 2001, the position of the track assembly 1 can be adjusted in the width direction. Moreover, the second adjustment unit 20 adopts the structure of the second screw 2001 and the second nut 2002, which can use existing standard parts, resulting in lower cost. Furthermore, the equipped second nut 2002 can be used for tightening, which helps to ensure the stability of the track assembly 1 after its position is adjusted in the width direction.

[0080] As a further preferred embodiment, the adjustment structure of this embodiment also includes a third adjustment unit 30 disposed on the support frame 22. The third adjustment unit 30 has a bottom pushing part that pushes the bottom of the track assembly 1, and the bottom pushing part can adjust the height position of the track assembly 1. The third adjustment unit 30 can be used to push the bottom of the track assembly 1 by the bottom pushing part to further adjust the height position of the track assembly 1. The third adjustment unit 30 and the first adjustment unit 10 are used in conjunction to realize two adjustments of the height of the track assembly 1, namely coarse adjustment and fine adjustment, so as to further ensure the levelness and installation accuracy of the track assembly 1.

[0081] Specifically, the third adjustment unit 30 includes a plurality of adjusting bolts 3001 arranged at intervals and screwed onto the support frame 22, that is, a plurality of adjusting bolts 3001 screwed onto the support plate 223. The adjusting bolts 3001 are arranged vertically and are installed from the lower surface of the support plate 223, extending partially above the upper surface of the support plate 223. The aforementioned bottom pushing part is formed by the end of the adjusting bolt 3001. By screwing in or out the adjusting bolt 3001, the height position of the track assembly 1 can be adjusted.

[0082] As a further preferred embodiment, the adjustment structure of this embodiment also includes a fourth adjustment unit 40 disposed on the support frame 22. The fourth adjustment unit 40 can adjust the position of the track assembly 1 in the length direction. This can eliminate deviations in the length direction during the installation of the track assembly 1, and help improve the docking accuracy between two adjacent track assemblies 1.

[0083] Specifically, the fourth adjustment unit 40 includes a first fixing hole 4001 disposed on the support plate 223, which is used to fix the track assembly 1. The first fixing hole 4001 is an elongated hole, and its long axis extends along the length of the track assembly 1. The track assembly 1 is fixed to the support frame 22 by a fixing bolt 111 passing through a second fixing hole 110 on the track assembly 1 and the fixing bolt 111 in the first fixing hole 4001. Furthermore, since the first fixing hole 4001 is an elongated hole extending along the length of the track assembly 1, the position of the track assembly 1 can be adjusted by fixing the fixing bolt 111 at different positions in the first fixing hole 4001.

[0084] Furthermore, as a further preferred embodiment, in this embodiment, the second fixing hole 110 provided on the track assembly 1 is also an elongated hole; however, the long axis of the second fixing hole 110 extends along the width direction of the track assembly 1. In this case, the arrangement of both the first fixing hole 4001 and the second fixing hole 110 as elongated holes can eliminate errors in the installation process of the track assembly 1, ensuring that the track assembly 1 is smoothly installed on the support frame 22.

[0085] Reference Figure 1 , Figure 5 and Figure 6 As shown, in a preferred embodiment, the track assembly 1 of this embodiment includes a track body 100, and a first connecting seat 11 and a second connecting seat 12 disposed on the track body 100. The first connecting seats 11 are located at both ends of the track body 100, and each first connecting seat 11 is connected to a pre-embedded tooling assembly 2 located at the end of the track body 100. The second connecting seat 12 is located between the two first connecting seats 11 and is connected to a reinforcing assembly 3.

[0086] In specific implementation, the first connecting seat 11 is screwed to the support plate 223 in the pre-embedded tooling assembly 2. For example... Figure 2 and Figure 3 As shown, the end plate connecting seat 11 is provided with a second fixing hole 110, and the support plate 223 is provided with a first fixing hole 4001. The first connecting seat 11 is screwed to the support plate 223 by the fixing bolts 111 passing through the first fixing hole 4001 and the second fixing hole 110, that is, the track assembly 1 is screwed to the support frame 22.

[0087] In the above structure, a first connecting seat 11 is provided at both ends of the track body 100, and a second connecting seat 12 is provided between the two first connecting seats 11, so that the first connecting seat 11 is connected to the corresponding pre-embedded tooling component 2, and the second connecting seat 12 is connected to the reinforcing component 3. This can provide stable support for the track component 1, and also enhance the load-bearing capacity of the middle part of the track body 100, effectively resisting the bending stress generated by the track body 100 during use.

[0088] As a further preferred embodiment, at least one third connecting seat 13 is also provided on the track body 100, and the number of pre-embedded tooling components 2 matches the sum of the number of third connecting seats 13 and first connecting seats 11. Furthermore, a second connecting seat 12 is provided between the first connecting seat 11 and the adjacent third connecting seat 13, as well as between two adjacent third connecting seats 13.

[0089] In specific implementation, the third connecting seat 13 is also provided with a second fixing hole 110, and the third connecting seat 13 is also screwed to the support plate 223 by fixing bolts 111 passing through the first fixing hole 4001 and the second fixing hole 110, that is, the track assembly 1 is screwed to the support frame 22.

[0090] In this embodiment, the provision of the third connecting seat 13 can further increase the connection points between the track body 100 and the pre-embedded tooling assembly 2, thereby further improving the stability of the track body 100 support. Moreover, compared with the track structure with burrs, the track assembly 1 with the first connecting seat 11, the third connecting seat 13, and the second connecting seat 12 in this embodiment also helps to reduce the weight of the track and facilitates lightweight design.

[0091] In addition, in this embodiment, a sensor mounting box 5 is also provided on the track body 100. The inner cavity of the sensor mounting box 5 is used to install the sensor 514, and each side wall of the sensor mounting box 5 is provided with a through hole 511. A plug 512 can be selectively installed at each through hole 511. The sensor mounting box 5 provided on the track body 100 provides installation space for the sensor 514 and facilitates the feedback of position signals. The design of providing through holes 511 and plugs 512 on each side wall of the sensor mounting box 5 facilitates the wiring and maintenance of the sensor 514. At the same time, according to actual needs, appropriate through holes 511 can be selected for wiring harness arrangement, and unsuitable through holes 511 can be sealed with plugs 512, thus improving the effectiveness of the sensor mounting box 5.

[0092] In terms of specific structure, such as Figure 6 As shown, the sensor mounting box 5 includes a lower box body 51 and a cover plate 52 connected to the lower box body 51. The lower box body 51 has a first mounting hole 510, and the track body 100 has a second mounting hole 103. The lower box body 51 is screwed onto the track body 100 by second bolts 516 passing through the first mounting hole 510 and the second mounting hole 103. The cover plate 52 is mounted on the lower box body 51 by third bolts 522, and the cover plate has set screw holes 520 for installing set screws 521, facilitating the disassembly, assembly, and maintenance of the sensor mounting box 5.

[0093] Additionally, a mounting bracket 513 is provided inside the lower housing 51, and the sensor 514 is mounted on the mounting bracket 513. The mounting bracket 513 has a mounting hole 5131 that connects to the lower housing 51. The mounting bracket 513 is screwed onto the lower housing 51 by a first bolt 515 passing through the mounting hole 5131. Preferably, the mounting hole 5131 is an elongated hole, with its long axis extending along the height direction of the sensor mounting box 5. This allows for fine-tuning of the position of the sensor 514 relative to the sensor mounting box 5 according to actual conditions.

[0094] Still refer to Figure 7As shown, each side wall of the lower box 51 is provided with a through hole 511. A plug 512 is selectively provided at the through hole 511. The through hole 511 is used to reserve a position for the conduit through which the wire harness passes. Specifically, one or more of the through holes 511 can be selected to arrange the conduit according to the actual wiring requirements. The through holes 511 that do not need to be arranged with conduits are blocked by the plug 512.

[0095] In this embodiment, combined with Figure 1 and Figure 8 As shown, multiple track assemblies 1 are connected end to end in sequence, and adjacent track bodies 100 are connected together by corresponding third connecting seats 13. In this embodiment, in order to ensure the consistency of the gap between adjacent track bodies 100, a gap tooling plate 6 is provided at the docking part of two adjacent track bodies 100. After the position of the track assembly 1 is fixed, the gap tooling plate 6 can be pulled out from between the two track bodies 100.

[0096] At this point, the track assembly 1 adopts a multi-segment sequentially connected design, which allows for flexible combination of the number of track assemblies 1 according to the test length requirements, and facilitates transportation. The gap fixture plate 6 set between two adjacent track bodies 100 can ensure that the gap between adjacent track bodies 100 is uniform and consistent during track installation, ensure that the expansion joints between track bodies 100 are reasonably configured, and facilitate the disassembly of the gap fixture plate 6 after the position of the track assembly 1 is fixed.

[0097] In practice, the gap tooling plate 6 has an insertion port 600 that is inserted into the track body 100. When the track assembly 1 is installed, the gap tooling plate 6 is inserted into the mating part of two adjacent track bodies 100. After the position of the track assembly 1 is fixed, the gap tooling plate 6 can be pulled out from between the two track bodies 100.

[0098] Furthermore, in this embodiment, each track body 100 is provided with a positioning groove 101 and a positioning end face 104 located at the groove opening 102 of the positioning groove 101. The positioning groove 101 and the positioning end face 104 are used to match the docking fixture 7 to position the relative position between two adjacent track bodies 100. In this way, by utilizing the cooperation between the positioning end face 104 and the positioning groove 101 on the adjacent track bodies 100 and the docking fixture 7, the relative position between two adjacent track bodies 101 can be positioned, effectively controlling the track docking error and helping to ensure the overall accuracy of the traction track.

[0099] It should be noted that the positioning groove 101 and the positioning end face 104 provided on the rail body 100 are preferably the structures of the rail body 100 itself. Among them, the positioning groove 101 is the positioning groove, and the positioning end face 104 is the upper end face of the rail body. The relative positions between two adjacent rail bodies 100 include the flatness and straightness between the two rail bodies 100.

[0100] In terms of the specific structure, in combination with Figure 1 and Figure 9 As shown, as a preferred embodiment, the docking tooling part 7 of this embodiment includes a first positioning block 71 and a second positioning block 72. The first positioning block 71 can be positioned on the positioning end face 104 of the adjacent rail body 100. The second positioning block 72 can rotate relative to the first positioning block 71, and has a first position that can be positioned in the positioning groove 101, and a second position that can be disengaged from the notch 102 of the positioning groove 101.

[0101] Still referring to Figure 1 and Figure 9 As shown, the first positioning block 71 and the second positioning block 72 are connected by screwing, so that the second positioning block 72 can rotate relative to the first positioning block 71. When positioning the adjacent rail bodies 100, the first positioning block 71 is positioned on the positioning end face 104, and the second positioning block 72 is in the first position. After the positioning of the adjacent rail bodies 100 is completed, the second positioning block 72 rotates from the first position to the second position, so that the second positioning block 72 can be disengaged from the notch 102. Among them, the above-mentioned positioning end face 104 is constituted by the upper end face of the rail body 100.

[0102] As Figure 9 shown, the cross-section of the first positioning block 71 is in a "convex" shape, and has a first convex portion located at the notch 102, and positioning surfaces 711 for positioning on the rail body 100 on both sides of the first convex portion. During specific implementation, the positioning surfaces 711 are positioned on the positioning end face 104. The cross-section of the second positioning block 72 is also in a "convex" shape and has a second convex portion. The first convex portion and the second convex portion are arranged oppositely, and a first threaded hole 710 is provided on the first convex portion, and a second threaded hole 720 is provided on the second convex portion. The first positioning block 71 and the second positioning block 72 are connected by screwing with a fastening bolt 74 screwed into the first threaded hole 710 and the second threaded hole 720.

[0103] In addition, as a further preferred embodiment, a measuring plate 73 is also provided on the first positioning block 71. The measuring plate 73 has a through hole 730 for light to pass through. The measuring plate 73 cooperates with a straightness detection device to detect the straightness between adjacent track bodies 100. In specific implementation, the first positioning block 71 is provided with a slot 712, which extends along the width direction of the track body 100, and the measuring plate 73 is engaged in the slot 712.

[0104] In practical use, the first positioning block 71 and the second positioning block 72 are first pre-connected together, with the second positioning block 72 in the second position. Then, the second positioning block 72 is placed into the docking position between two adjacent track bodies 100 through the slot 102 of the positioning groove 101. Next, the first positioning block 71 is positioned on the upper surface of the two adjacent track bodies 100, and the second positioning block 72 is rotated from the second position to the first position, thus positioning the second positioning block 72 in the positioning groove 101 of the two adjacent track bodies 100. Then, the first positioning block 71 and the second positioning block 72 are fastened together, so that the two adjacent track bodies 100 are well docked together. After docking, the measuring plate 73 is inserted into the slot 712 of the first positioning block 71, providing a measurement basis for measuring the straightness of the track.

[0105] In this embodiment, the traction track is poured in two stages. The first pour is located below the upper surface of the support frame 22. The second adjustment unit 20, the third adjustment unit 30, and the fourth adjustment unit 40 are arranged on the same layer to adjust the track body 100 along its length, width, and height. Before the first pour, the first adjustment unit 10 is used for coarse height adjustment to ensure the height and levelness of the track body 100 meet the requirements. The first adjustment unit 10 is then tightened before the first pour. It should be noted that the height of the track body 100 should not be higher than the ground; a slightly lower height is preferable. This allows for fine-tuning of the height later using the third adjustment unit 30, which can raise the track slightly. Once the track body is in contact with the support plate 223, it cannot be lowered further.

[0106] After the first pour is completed, check whether there are any changes in the height, length, and width of the track body 100. If any discrepancies are found, adjust the second adjustment unit 20, the third adjustment unit 30, and the fourth adjustment unit 40 in coordination until the requirements are met. Then, perform the second pour to complete the installation of the traction track. The adjustment structure in this embodiment can perform a final check on the installation accuracy of the track before the track construction is completed, and can make fine adjustments to ensure that the track meets the technical requirements after installation, thereby improving the accuracy of the collision test.

[0107] In this embodiment, the traction rail consists of a rail assembly 1 and multiple pre-embedded tooling assemblies 2 arranged at intervals. A reinforcing assembly 3 is provided between two adjacent pre-embedded tooling assemblies 2, so that the reinforcing assembly 3 is connected to the adjacent pre-embedded tooling assemblies 2 and the rail assembly 1, thereby forming an integrated support structure for the rail assembly 1. This can improve the overall structural strength and rigidity of the traction rail, reduce the risk of deformation or being pulled out of the pre-embedded parts of the rail assembly 1, and has a good performance.
