[0002] To meet the requirements of cold protection and heat insulation, rail vehicles usually lay heat insulation materials on the car body and use cold-proof nails to fix the heat insulation materials. At present, cold-proof nails are generally fixed by welding on the roof. The needles of the cold-proof nails are exposed, which can easily cut the hands of construction workers during construction, posing a safety hazard. The construction process is not very technical, and the maintenance is poor. Moreover, practice has shown that the reliability of fixing heat insulation materials with cold-proof nails is low.

[0003] In conclusion, improving the maintainability of vehicle body accessories is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0028] A vehicle body, comprising the vehicle body accessory mounting structure described in any of the preceding claims.

[0029] A rail vehicle comprising the aforementioned vehicle body.

[0030] In this application, a vertically extending groove is provided at the bottom of the vehicle body, with the groove opening facing downwards. The groove opening width C is smaller than the groove width. Correspondingly, the first end of the fixing rod has a first positioning part. The width A of the first positioning part is smaller than its length B, and the width A of the first positioning part is smaller than the groove opening width C, while the length B of the first positioning part is greater than the groove opening width C. When the width direction of the first positioning part is parallel to the groove opening width direction, the first positioning part can pass through the groove opening and be inserted into it. When the length direction of the first positioning part has a non-zero angle with the groove opening width direction, the first positioning part cannot pass through the groove opening, thus the first positioning part can be engaged in the groove, thereby limiting the fixing rod axially and specifically preventing the fixing rod from moving downwards.

The groove has a depth margin, and the depth margin is greater than or equal to the length of the second positioning part along the axial direction of the fixing rod. The fixing rod is then pushed upward so that the first positioning part abuts against the top wall of the groove, i.e., the bottom of the groove. The fixing rod can then rotate around its axial direction. Then, the fixing rod is rotated so that the length direction of the first positioning part at its first end forms a non-zero angle with the width direction of the groove on the vehicle body. Finally, the fixing rod is pulled in the opposite direction so that the second positioning part is inserted into the opening of the groove, thus completing the installation of the fixing rod.

[0033] Secondly, a mounting component is detachably installed on the first side of the vehicle body. Correspondingly, the fixing rod also has a third positioning part, which is located below the first positioning part.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Another core aspect of this application is to provide a vehicle body accessory mounting assembly applied to the aforementioned vehicle body accessory mounting structure. Yet another core aspect of this application is to provide a vehicle body including the aforementioned vehicle body accessory mounting structure, and a rail vehicle including the aforementioned vehicle body.

[0049] This application provides a vehicle body accessory mounting structure, including a fixing rod 1 and a mounting member 2. The fixing rod 1 passes through a groove 61 in a vehicle body 6 for mounting vehicle body accessories. The first end of the fixing rod 1 has a first positioning part 11, a second positioning part 12, and a third positioning part 13. The first positioning part 11 can be inserted into or removed from the groove of the groove 61 and abuts against the groove wall of the groove 61. The second positioning part 12 is engaged in the groove opening of the groove 61 to restrict the rotation of the fixing rod 1 around the axial direction. The third positioning part 13 is located on the rod section of the fixing rod 1 extending into the vehicle body 6. The mounting member 2 is mounted on the first side of the vehicle body 6 and is detachably connected to the third positioning part 13 to restrict the movement of the fixing rod 1 along the axial direction. It should be noted that vehicle body accessories refer to components installed on the vehicle body 6, such as heat insulation layer 7, cables, wire troughs, and other structures.

[0050] refer to Figure 1 As explained, a vertically extending groove 61 is provided at the bottom of the vehicle body 6. The opening of the groove 61 faces downward, and the width C of the groove opening is smaller than the width of the groove body. (See reference...) Figure 5 and Figure 6 As explained, the top of the fixing rod 1 has a first positioning part 11. The width A of the first positioning part 11 is less than its length B, and the width A of the first positioning part 11 is less than the groove width C of the slide 61, while the length B of the first positioning part 11 is greater than the groove width C of the slide 61. When the width direction of the first positioning part 11 is parallel to the groove width direction of the slide 61, the first positioning part 11 can pass through the groove of the slide 61 and be inserted into it. When the length direction of the first positioning part 11 has a non-zero angle with the groove width direction of the slide 61, for example, an angle of 30 degrees or... Figure 6 When the angle is 90 degrees, the first positioning part 11 cannot pass through the groove of the slide 61, so that the first positioning part 11 can be engaged in the slide, thereby limiting the fixing rod 1 along the axial direction, specifically preventing the fixing rod 1 from moving downward.

[0051] Furthermore, the fixing rod 1 also has a second positioning part 12, which is located below the first positioning part 11. The size of the second positioning part 12 is similar to the width of the groove 61. The second mounting part is fitted with the groove 61 with a clearance, thereby restricting the fixing rod 1 from rotating around the axial direction.

[0052] To perform the installation, refer to Figure 1 As shown, the fixing rod 1 is placed on the underside of the vehicle body 6, such that the first positioning part 11 at the top of the fixing rod 1 is positioned such that it is perpendicular to the vehicle body 6. Figure 5 As shown in the diagram, push the fixing rod 1 upwards so that the first positioning part 11 passes through the opening of the slide groove 61 and is inserted into it. The slide groove 61 has a depth allowance, which is greater than or equal to the length of the second positioning part 12 along the axial direction of the fixing rod 1. Then, push the fixing rod 1 upwards so that the first positioning part 11 abuts against the top wall of the slide groove 61, i.e., the bottom of the slide groove 61. The fixing rod 1 can then rotate axially. Then, rotate the fixing rod 1 so that the distance between the first positioning part 11 at its top and the vehicle body 6 is... Figure 6 In the indicated position, pull the fixing rod 1 down to insert the second positioning part 12 into the groove of the slide 61, thus completing the installation of the fixing rod 1.

[0053] Secondly, a mounting component 2 is detachably provided below the vehicle body 6. Correspondingly, the fixing rod 1 also has a third positioning part 13, which is located below the first positioning part 11. The second positioning part 12 is used for detachable connection with the mounting component 2, which can realize the axial limitation of the fixing rod 1, specifically limiting the fixing rod 1 from moving upward.

[0054] It should be noted that the method of detachable connection between the fixing rod 1 and the mounting part 2 is not limited.

Correspondingly, the mounting part 2 adopts a locking nut. In use, the mounting part 2 is sleeved on the outside of the second positioning part 12 of the fixed rod 1 and connected to it by threads. This setting can not only meet the connection requirements, but also reduce the difficulty of assembly and maintenance.

[0061] Based on the above embodiment, it also includes a connecting tube 3, and the clamping member 5 is detachably connected to the second end of the fixing rod 1 through the nested connecting member 4; the second end of the fixing rod 1 has a fourth positioning part 14, the first end of the connecting tube 3 is sleeved on the outside of the fixing rod 1 and tightly fitted to the fourth positioning part 14; the nested connecting member 4 is inserted into the second end of the connecting tube 3, and the nested connecting member 4 is threadedly connected to the clamping member 5.

[0062] refer to Figure 1 and Figure 4 As explained, the fixing rod 1 also has a fourth positioning part 14, which is located below the third positioning part 13. The top end of the connecting pipe 3 is sleeved on the outside of the fixing rod 1, and the inner wall of the connecting pipe 3 is interference-fitted with the third fixing part to realize the assembly of the fixing rod 1 and the connecting pipe 3. Correspondingly, a nested connector 4 is inserted into the lower end of the connecting pipe 3. The clamping part 5 is sleeved on the nested connector 4 and threadedly connected to it. After the clamping part 5 is installed in place, it clamps the vehicle body accessories.

[0063] Optionally, the nested connector 4 has a threaded hole, and the threaded section of the clamping member 5 is inserted into the threaded hole and threadedly connected to the nested connector 4; Reference Figure 1 and Figure 4 As explained, the nested connector 4 is a threaded tube, that is, the inner wall of the nested connector 4 is machined with internal threads, and the clamping member 5 can be a threaded rod, that is, the outer surface of the clamping member 5 is machined with external threads.

[0064] Optionally, the nested connector 4 is a stud, with the first end of the nested connector 4 inserted inside the connecting pipe 3. The clamping member 5 is a nut structure, fitted onto the outside of the second end of the nested connector 4 and threadedly connected to the nested connector 4. Specifically, the lower end of the nested connector 4 has an external thread machined on its outer circumferential surface, and the lower end of the nested connector 4 extends to the lower side of the vehicle body accessory. The clamping member 5 is fitted onto the outside of the lower end of the nested connector 4 and threadedly connected to the nested connector 4. After the clamping member 5 is installed in place, it is clamped onto the vehicle body accessory.

[0065] It should be noted that the type of connecting pipe 3 is not limited, as long as it can meet the connection requirements of the fixing rod 1 and the nested connector 4. For example, the connecting pipe 3 can be a through pipe. Preferably, such as... Figure 1 As shown, the middle section of the length of the connecting pipe 3 is a solid structure, while both the first and second ends of the connecting pipe 3 have blind holes.

[0066] Based on the above embodiment, the fixing rod 1 is a T-bolt; the first positioning part 11, the second positioning part 12, the third positioning part 13, and the fourth positioning part 14 are connected in sequence; the second positioning part 12 is a quadrangular prism, and the side length of the second positioning part 12 is equal to the width of the first positioning part 11; the diameter of the third positioning part 13 is smaller than the side length of the second positioning part 12; and the width of the fourth positioning part 14 is greater than the diameter of the third positioning part 13.

[0067] refer to Figure 1 As explained, the first positioning part 11, the second positioning part 12, the third positioning part 13, and the fourth positioning part 14 of the fixing rod 1 are connected sequentially from top to bottom. The first positioning part 11 is a T-shaped platform, and the corresponding second positioning part 12 is a quadrangular prism with a square cross-section. The two opposite sides of the second positioning part 12 are coplanar with the two sides of the first positioning part 11 along its own width direction. During assembly, after the fixing rod 1 is inserted into the slide groove 61 and the first positioning part 11 contacts the bottom of the slide groove 61, it is rotated 90 degrees and then the fixing rod 1 is pulled down to allow the second positioning part 12 to be inserted into the groove of the slide groove 61. This reduces both the manufacturing difficulty and the disassembly and assembly difficulty.

[0068] Furthermore, the third positioning part 13 is a threaded rod to enable assembly with the mounting part 2; the fourth positioning part 14 can be a prism or a cylinder, etc., and the maximum width of the fourth positioning part 14 is greater than the diameter of the third positioning part 13, so as to determine whether the connecting pipe 3 and the fixing rod 1 are assembled in place.

[0069] Of course, the second positioning part 12 and the first positioning part 11 are not limited to the above-described examples and embodiments, as long as they can meet the installation and positioning requirements.

[0070] In some embodiments, the second positioning part 12 includes at least a pair of opposing and parallel first side surfaces and a pair of opposing and parallel second side surfaces. Correspondingly, the first positioning part 11 adopts a long strip with parallel opposing sides, while the two opposing first side surfaces of the second positioning part 12 are coplanar or recessed within the corresponding side surfaces of the first positioning part 11 along its own width direction. (Refer to...) Figure 5 and Figure 7 As explained, the second positioning part 12 can pass through the opening of the slide groove 61 via the first side; two second side surfaces are arranged opposite each other in the second positioning part 12 and recessed at both ends of the first positioning part 11 along its own length direction, for reference.

[0071] Preferably, in some embodiments, the number of edges of the second positioning part 12 is greater than or equal to 4 and is an even number, and the included angle between any adjacent edges of the second positioning part 12 is equal. Then, during assembly, after the fixing rod 1 is inserted into the slide groove 61 and the first positioning part 11 contacts the bottom of the slide groove 61, the target angle is rotated, and then the fixing rod 1 is pulled down to allow the second positioning part 12 to be inserted into the opening of the slide groove 61. The target angle is equal to 360° divided by the number of edges of the second positioning part 12. Where the number of edges of the second positioning part 12 is equal to 4, ... Figure 5 and Figure 6 As shown.

[0072] In some embodiments, the fourth positioning part 14 is a polygonal prism, such as an octagonal prism or a dodecagonal prism, to increase the friction with the connecting pipe 3.

[0073] In some embodiments, the outer peripheral surface of the nested connector 4 has anti-slip texture, which can be diamond knurling or transverse texture, etc., to improve the anti-loosening torque.

The clamping member 5 is pressed onto the wiring harness 8 or a clamp for fixing the wiring harness 8, etc., to indirectly press the heat insulation layer 7 onto the first side of the vehicle body 6.

[0075] Preferably, based on the above embodiment, both the first and second ends of the connecting pipe 3 have blind holes. The second end of the fixing rod 1 is inserted into the blind hole at the first end of the connecting pipe 3, and the nested connector 4 is inserted into the blind hole at the second end of the connecting pipe 3. The connecting pipe 3 is a non-metallic component, so as to play the role of blocking thermal bridges. When the fixed vehicle body accessory is the heat insulation layer 7, the vehicle's heat preservation performance can be improved. Furthermore, the connecting pipe 3, the fixing rod 1, and the nested connector 4 are injection molded.

[0076] In addition to the aforementioned vehicle body accessory mounting structure, this application also provides a vehicle body accessory mounting assembly applied to the vehicle body accessory mounting structure disclosed in the above embodiments.

[0077] In some embodiments, the vehicle body accessory mounting structure includes only the fixing rod 1 and the mounting component 2.

[0078] In some embodiments, the vehicle body accessory mounting structure includes a fixing rod 1, a mounting component 2, and a clamping component 5.

[0079] In some embodiments, the vehicle body accessory mounting structure includes a fixing rod 1, a mounting component 2, a connecting pipe 3, and a nested connecting component 4.

[0080] In some embodiments, the vehicle body accessory mounting structure includes a fixing rod 1, a mounting component 2, a connecting pipe 3, a nested connecting component 4, and a clamping component 5.

[0081] Of course, the composition of the vehicle body accessory mounting structure is not limited to the above-described exemplary embodiments. All other embodiments that include the fixing rod 1 and the mounting component 2 in the above-described vehicle body accessory mounting structure and meet the requirements of the vehicle body accessory mounting structure disclosed in the above embodiments are within the scope of protection of this application.

[0082] In addition to the aforementioned vehicle body accessory mounting structure, this application also provides a vehicle body accessory mounting method applied to the vehicle body accessory mounting structure disclosed in the above embodiments, the vehicle body accessory mounting method comprising the following steps:

[0083] Step S1: Align the first end of the fixing rod 1 with the groove 61 located on the first side of the vehicle body 6, so that the first positioning part 11 of the fixing rod 1 extends along the length direction of the groove 61, and then push the fixing rod 1 into it; it can be understood that, referring to Figure 4 As explained, align the top of the fixing rod 1 with the bottom opening of the slide groove 61, as shown in the alignment. Figure 5 and Figure 7As shown, pushing the fixing rod 1 upwards will allow it to pass through the slot and be inserted into the slide groove 61 from bottom to top.

[0084] Step S2: After the first positioning part 11 abuts against the bottom of the slide groove 61, rotate the fixing rod 1 so that the extension direction of the first positioning part 11 has a non-zero angle with the length direction of the slide groove 61; it can be understood that during the process of pushing the fixing rod 1, after the top of the fixing rod 1 abuts against the top bottom of the slide groove 61, it is pushed into place. Next, push the fixing rod 1 to rotate around its own axis to move to the snap-fit ​​position. The snap-fit ​​position is referenced. Figure 6 and Figure 8 The orientation of the second positioning part 12 of the middle fixed rod 1.

[0085] Step S3: Pull the fixing rod 1 in the reverse direction so that the second positioning part 12 of the fixing rod 1 is inserted into the groove of the slide 61, and the first positioning part 11 abuts against the stepped surface of the slide 61; it can be understood that after the position of the fixing rod 1 is adjusted, pulling the fixing rod 1 downward in the reverse direction will cause the fixing rod 1 to move downward, and during the downward movement of the fixing rod 1, the second positioning part 12 will retract into the groove of the slide 61, as shown. Figure 6 and Figure 8 As shown, since the width direction of the first positioning part 11 of the fixing rod 1 is offset from the width direction of the slide groove 61, Figure 6 and Figure 8 In the embodiment shown, the length direction of the first positioning part 11 is perpendicular to the width direction of the slide groove 61. After the fixed rod 1 moves downward to the end of its stroke, the first positioning part 11 will abut against the stepped surface of the slide groove 61. It should be noted that the width of the groove opening of the slide groove 61 is smaller than the width of the groove body, that is, the slide groove 61 is a variable cross-section groove. The stepped surface of the slide groove 61 refers to the connection surface between the groove body and the variable cross-section position of the groove opening.

[0086] Based on the above embodiment, after step S3, the method further includes: fixing the mounting part 2 to the vehicle body 6; it can be understood that after the mounting part 2 is installed in place, it is fixed to prevent the mounting part 2 from being misaligned.

[0087] In addition to the aforementioned vehicle body accessory mounting structure, this application also provides a vehicle body including the vehicle body accessory mounting structure disclosed in the above embodiments, and a rail vehicle including the aforementioned vehicle body. For the structure of the other parts of the vehicle body and the rail vehicle, please refer to the prior art, which will not be repeated here.
