Description

Technical Field

[0001] The utility model relates to the technical field of truck sidewalls, in particular to a truck sidewall buffer structure. Background Art

[0002] Trucks are generally called trucks, which are mainly used to transport goods. Sometimes they also refer to vehicles that can tow other vehicles. They belong to the category of commercial vehicles. Generally, they are divided into heavy and light according to the weight of the vehicle. Most trucks are powered by diesel engines, while some light trucks use gasoline, LPG or natural gas.

[0003] Trucks are generally compartments of railings. When the compartment encounters a collision, the outer end of the truck railing is very likely to be damaged. Currently, there are corner protection structures for the outer ends of truck railings (such as publication number CN206384055U). The corner protection reduces the damage to the outer end of the railing when the truck accidentally collides. At the same time, the deformation buffer space reserved on the L-shaped inner side of the corner guard can play a buffering role when subjected to force, reduce the vibration of the vehicle body, and also play a role in noise reduction.

[0004] In order to prevent paint from sticking between the various assemblies of the tailgate carriage, the tailgate carriage structure on the market usually reserves a certain gap between the side panel assembly, the rear panel assembly and the bottom panel assembly, and between the side panel assembly and the rear panel assembly. When the side panel assembly and the rear panel assembly are locked, the upper portion of the side panel assembly is pulled and contacts the rear panel assembly, and the upper portion of the side panel assembly causes paint loss and rust due to the rigid contact with the rear panel assembly. The existing corner guard structure at the outer end of the tailgate can only protect the end of the tailgate from colliding with external objects, and cannot avoid the rigid contact between the upper portion of the side panel assembly and the rear panel assembly; and the existing corner guard structure cannot ensure the uniformity of the gap. When the side panel assembly and the rear panel assembly are locked and the upper portions are in rigid contact, the upper and lower gaps between the side panel assembly and the rear panel assembly will be uneven, seriously affecting the appearance. Utility Model Content

[0005] In order to solve the technical problem in the above-mentioned background technology that the existing corner guards at the ends of the side panels cannot avoid the rigid contact between the upper part of the side panel assembly and the rear panel assembly, the utility model provides a truck side panel buffer structure.

[0006] The technical solution of this utility model is as follows:

[0007] The utility model provides a buffer structure for a truck sideboard, comprising: a rear panel assembly and a side panel assembly, a buffer pad is arranged between the rear panel assembly and the side panel assembly, the buffer pad is fixedly arranged on the upper part of the rear panel assembly, a bolt rod is installed on the rear panel assembly, the buffer pad is located in front of the bolt rod, when the rear panel assembly and the side panel assembly are locked by the bolt rod, the upper part of the side panel assembly is pulled, contacts with and squeezes the buffer pad, so that the thickness of the buffer pad is reduced, which can not only play a buffering role and avoid rigid contact between the rear panel assembly and the upper part of the side panel assembly, but also ensure that the buffer pad is not exposed, improve the aesthetics and avoid the influence of the buffer pad on the work of the bolt rod.

[0008] Preferably, the buffer pad is L-shaped and its structure is suitable for the rear plate assembly, which facilitates the installation of the buffer pad.

[0009] Preferably, the wall thickness of the buffer pad is larger than the gap between the rear panel assembly and the side panel assembly. The upper part of the side panel assembly is pulled, contacts and squeezes the buffer pad, so that the thickness of the buffer pad is reduced. This can ensure that the upper and lower gaps between the rear panel assembly and the side panel assembly are uniform, and prevent paint loss and rusting problems caused by rigid contact between adjacent components.

[0010] Preferably, the rear plate assembly includes a rear plate body containing a cavity, and a blocking plate is fixedly provided on both sides of the rear plate body adjacent to the side plate assembly for sealing the two sides of the rear plate body.

[0011] Preferably, the blocking plate is a U-shaped structure, which is convenient for installation and use of the blocking plate.

[0012] Preferably, a first circular hole is provided on one side of the blocking plate located on the inner side of the vehicle body, a second circular hole is provided on the side close to the side panel assembly, and a third circular hole is provided on the rear panel body and is coaxially arranged with the first circular hole. The buffer pad is fixed in the first circular hole and the second circular hole by means of a fixing column, and the buffer pad can be quickly positioned and installed through the cooperation between the circular hole and the fixing column.

[0013] Preferably, the first circular hole, the second circular hole and the third circular hole have the same diameter, and the buffer pad is fixedly provided with two fixing columns corresponding to the first circular hole and the second circular hole, so as to facilitate the fixed installation of the buffer pad on the rear plate assembly.

[0014] Preferably, the head of the fixing column is a variable diameter structure, which can facilitate the fixing column to be inserted into the corresponding circular hole, thereby facilitating the installation of the buffer pad.

[0015] Preferably, the root diameter of the fixing column is smaller than the maximum diameter of the head thereof, which can effectively limit the position of the fixing column and prevent the fixing column from being pulled out of the corresponding circular hole during use.

[0016] Preferably, the root diameter of the fixing column is larger than the diameter of the first circular hole, so that the fixing column and the corresponding circular hole can be interference fit to prevent the buffer pad from shaking.

[0017] It can be seen from the above technical solutions that the advantages of the utility model are:

[0018] 1. A buffer pad is provided between the rear panel assembly and the side panel assembly. The buffer pad is fixedly arranged on the upper part of the rear panel assembly and is located in front of the bolt rod. When the rear panel assembly and the side panel assembly are locked by the bolt rod, the upper part of the side panel assembly is pulled, contacts with and squeezes the buffer pad, so that the thickness of the buffer pad is reduced. It can not only play a buffering role and avoid rigid contact between the rear panel assembly and the upper part of the side panel assembly, but also ensure that the buffer pad is not exposed, thereby improving the aesthetics and avoiding the influence of the buffer pad on the work of the bolt rod.

[0019] 2. The wall thickness of the buffer pad is greater than the gap between the rear panel assembly and the side panel assembly. When the upper part of the side panel assembly is pulled, it contacts and squeezes the buffer pad, which reduces the thickness of the buffer pad. This can ensure that the upper and lower gaps between the rear panel assembly and the side panel assembly are uniform and consistent, and prevent paint loss and rusting caused by rigid contact between adjacent components.

[0020] 3. The head of the fixed column is a variable diameter structure, which can facilitate the insertion of the fixed column into the corresponding circular hole, and facilitate the installation of the buffer pad. The root diameter of the fixed column is smaller than the maximum diameter of its head, which can effectively limit the position of the fixed column and prevent the fixed column from being pulled out of the corresponding circular hole during use.

[0021] 4. The root diameter of the fixing column is larger than the diameter of the first circular hole, so that the fixing column and the corresponding circular hole can be interference fit to prevent the buffer pad from shaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0032] In a typical implementation of the present invention, Figure 1-Figure 6 As shown in the figure, a truck sideboard buffer structure is proposed, comprising: a rear panel assembly 1, a side panel assembly 2 and a buffer mechanism. When the rear panel assembly 1 and the side panel assembly 2 are locked, the buffer mechanism is fixedly installed between the rear panel assembly 1 and the side panel assembly 2, and the buffer mechanism is located at the upper part of the rear panel assembly 1 and the side panel assembly 2. Figure 2 As shown, the buffer mechanism is located in front of the bolt rod 6 on the rear panel assembly 1, which not only plays a buffering role to avoid rigid contact between the rear panel assembly 1 and the upper part of the side panel assembly 2, but also ensures that the buffer mechanism is not exposed, thereby improving the aesthetics and avoiding the influence of the buffer mechanism on the operation of the bolt rod 6.

[0033] The buffer structure is a flexible buffer pad 3, which is L-shaped as a whole and is made of rubber material. In the present embodiment, the buffer pad 3 is made of EPDM material and has a wall thickness of 3 mm. After the railing is assembled, the gap between the rear panel assembly 1 and the side panel assembly 2 is generally 2 mm. The buffer pad 3 can not only play a buffering role to avoid rigid contact between the rear panel assembly 1 and the upper part of the side panel assembly 2, but also change the thickness of the buffer pad 3 itself by squeezing the buffer pad 3, thereby maintaining the gap between the rear panel assembly 1 and the upper part of the side panel assembly 2 at about 2 mm, thereby making the upper and lower gaps between the rear panel assembly 1 and the side panel assembly 2 uniform, thereby improving the aesthetics of the railing compartment.

[0034] like Figure 3-Figure 5 As shown, the rear panel assembly 1 includes a blocking plate 9 and a rear panel body 10. The rear panel body 10 is a baffle structure containing a cavity inside. Both sides of the rear panel body 10 adjacent to the side panel assembly 2 are connected to the internal cavity and are fixedly provided with a blocking plate 9 to seal both sides of the rear panel body 10. The blocking plate 9 is a U-shaped structure, and the blocking plate 9 is covered and fixedly arranged on both sides of the rear panel body 10 adjacent to the side panel assembly 2 by welding.

[0035] like Figure 4 As shown, the blocking plate 9 includes a first plane 12 and a second plane 13, the first plane 12 is perpendicular to the second plane 13, the first plane 12 is located on the inner side of the car, and the second plane 13 is close to the side panel assembly 2. A first circular hole 4 is opened on the first plane 12, and a second circular hole 5 is opened on the second plane 13. The first circular hole 4 and the second circular hole 5 have the same diameter, both of which are φ6mm. The first circular hole 4 and the second circular hole 5 are of the same height and are both located on the upper part of the rear half assembly 1 for fixing and installing the buffer pad 3; a through hole is opened on the second plane 13, For the installation of the bolt rod 6, the through hole is located behind the second circular hole 5; a third circular hole 11 is opened on the rear plate body 10, and the diameter of the third circular hole 11 is the same as that of the first circular hole 4. The third circular hole 11 corresponds to the first circular hole 4, that is, the first circular hole 4 is coaxially provided with a third circular hole 11, and the diameter of the third circular hole 11 is the same as that of the first circular hole 4. Therefore, when the blocking plate 9 is fixedly connected to the rear plate body 10, the first circular hole 4 and the second circular hole 5 can be connected to the corresponding third circular hole 11 respectively, so as to facilitate the installation of the buffer pad 3, as shown in detail. Figure 5 As shown, the side of the rear plate body 10 that is in contact with the first plane 12 of the blocking plate 9 is a fifth plane 16 , and a third circular hole 11 is provided on the fifth plane 16 . The third circular hole 11 is coaxially arranged with the first circular hole 4 .

[0036] like Figure 6As shown, the buffer pad 3 is an L-shaped structure, and a fixing column is fixed on each of the two inner surfaces of the buffer pad 3. Specifically, the buffer pad 3 includes a third plane 14 and a fourth plane 15 which are perpendicular to each other. The third plane 14 is used to fit with the first plane 12 of the blocking plate 9, and the fourth plane 15 is used to fit with the second plane 13 of the blocking plate 9. A first fixing column 7 is fixed on the third plane 14, and the first fixing column 7 is used to be inserted into the first circular hole 4 and the corresponding third circular hole 11. A second fixing column 8 is fixed on the fourth plane 15, and the second fixing column 8 is used to be inserted into the first circular hole 4 and the corresponding third circular hole 11. The first and second fixing columns 7 and 8 are inserted into the two circular holes 5 and extend into the cavity of the rear plate body 10. The heads of the first fixing columns 7 and the second fixing columns 8 are of variable diameter structure, specifically, the diameter gradually decreases in the direction away from the surface of the buffer pad 3, so as to facilitate insertion into the first and second circular holes 4 and 5. The root diameters of the first and second fixing columns 7 and 8 are the same, both of which are φ7mm, that is, the root diameters of the first and second fixing columns 7 and 8 are larger than the diameters of the first and second circular holes 4 and 5, so that the first and second fixing columns 7 and 8 can be interference fit with the corresponding first and second circular holes 4 and 5 to prevent the buffer pad 3 from shaking.

[0037] The root diameter of the first fixing column 7 and the second fixing column 8 is smaller than the maximum diameter of the head thereof, thereby effectively limiting the position of the fixing column and preventing the first fixing column 7 and the second fixing column 8 from being pulled out of the corresponding circular holes during use.

[0038] When the railing is assembled, the gap between the rear panel assembly 1 and the side panel assembly 2 is 2 mm. When the rear panel assembly 1 and the side panel assembly 2 are locked by the bolt rod 6, the upper part of the side panel assembly 2 is pulled, contacts and squeezes the buffer pad 3, so that the thickness of the buffer pad 3 is reduced from 3 mm to about 2 mm. This can ensure that the upper and lower gaps between the rear panel assembly 1 and the side panel assembly 2 are uniform, and prevent paint loss and rust problems caused by rigid contact between adjacent components.

[0039] In this embodiment, the buffer pad 3 is installed on the blocking plate 9 of the rear panel assembly 1. It can be understood that in other embodiments, the buffer pad 3 can also be installed at a position on the upper part of the side panel assembly 2 adjacent to the rear panel assembly 1. However, since the installation space at the rear panel assembly 1 is large and it is convenient to hide the buffer pad 3 after locking, the best choice is to install the buffer pad 3 on the rear panel assembly 1.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
