Technical Field

[0001] This application belongs to the technical field of vehicle cargo box equipment, and specifically relates to a guardrail assembly, a cargo box and a vehicle thereof. Background Art

[0002] The cargo box guardrail, also called a roll cage or a rollover protection frame, is installed at the front of the cargo box, near the rear windshield of the cab. In extreme cases, the cargo box guardrail plays a role in preventing the cargo from tipping over and hitting the cab, protecting the safety of the passengers in the back row of the cab. In addition, the cargo box guardrail also has the functions of fixing the cargo and beautifying the appearance of the vehicle.

[0003] Most of the traditional cargo box guardrails adopt a fixed structure. The guardrail is fixed to the left and right side walls of the cargo box by bolts, or is integrally welded to the cargo box. Such cargo box guardrails are limited by the structure and cannot expand other usage scenarios. Summary of the Invention

[0015] The first via hole further includes a first avoidance hole section for avoiding the first connecting shaft, and the second via hole further includes a second avoidance hole section for avoiding the second connecting shaft. The first avoidance section and the second avoidance section are arranged on the top plate.

[0016] In an exemplary embodiment of the present application, the elastic locking structure includes a first locking member, a second locking member, a positioning member, a torsion spring, a first fixing member, and a second fixing member. The first fixing member passes through one end of the first locking member and is fixed to the cavity wall of the installation cavity. The second fixing member passes through one end of the second locking member and is fixed to the cavity wall of the installation cavity. The positioning member is located between the first fixing member and the second fixing member and sequentially passes through the first locking member, the torsion spring, and the second locking member. One end of the torsion spring is connected to the first locking member, and the other end of the torsion spring is connected to the second locking member. Wherein,

[0017] One end of the first locking member is disposed opposite to the first horizontal and vertical hole section, and rotates when the first connecting shaft moves from the first vertical hole section to the first horizontal and vertical hole section, and causes the torsion spring to undergo elastic deformation synchronously;

[0031] In the embodiment of the present application, since the guardrail assembly is detachably connected between the first guide rail and the second guide rail and can be flipped relative to the first guide rail and the second guide rail. Therefore, the angle of the guardrail fence of the cargo box can be adjusted according to different usage scenarios of the user to change the state, so as to meet the usage requirements. For example: the guardrail assembly passes the first connecting shaft through the installation cavity and elastically abuts against the installation cavity through the elastic locking structure, the second connecting shaft is disengaged from the installation cavity, and then the fence is flipped to the angle required by the user (for example, the fence can be flipped to a state where it can prevent the goods from rolling and smashing the rear windshield and injuring the cab members); or, the guardrail assembly can also be assembled with multiple fences and the first guide rail and the second guide rail on the corresponding first limiting member and the second limiting member according to the usage requirements, which can play a role in preventing the loaded goods from moving and jumping out of the cargo box. At the same time, the usage angle of each fence can be adjusted; or, when the vehicle wheels are stuck in a sand pit during driving, the fence can be disassembled and placed under the wheels, which can help the vehicle get out of trouble quickly. Therefore, the usage scenarios of the guardrail assembly of this cargo box can be freely combined and used according to the user's needs.

In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of this application.

[0051] The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0052] As Figures 1 to 13 shown, this embodiment provides a guardrail assembly for a cargo box 6, and the guardrail assembly is installed behind the cab of a vehicle.

[0053] Combined with Figure 1 and Figure 13 shown, the guardrail assembly includes a fence 1, an elastic locking structure 3, and first guide rails 2a and second guide rails 2b for connecting the cargo box 6. The fence 1 is detachably connected between the first guide rail 2a and the second guide rail 2b through the elastic locking structure 3, and can be flipped relative to the first guide rail 2a and the second guide rail 2b.

[0054] Combined with Figure 1 , Figure 5 and Figure 6 shown, installation cavities 201 are provided in both the first guide rail 2a and the second guide rail 2b. First connecting shafts 11 and second connecting shafts 12 are spaced apart on two opposite sides of the fence 1, and both the first connecting shaft 11 and the second connecting shaft 12 can pass through the installation cavity 201.

[0055] It should be understood that after the first connecting shaft 11 and the second connecting shaft 12 are passed through the installation cavity 201, they can rotate relative to each other with the fence 1 without being fixed by the elastic locking structure 3, so that they can be flipped relative to the first guide rail 2a and the second guide rail 2b to adjust the angle relative to the cargo box 6.

[0056] Furthermore, both the first connecting shaft 11 and the second connecting shaft 12 have a first stroke and a second stroke in the installation cavity 201, and the directions of the first stroke and the second stroke intersect.

[0057] In this embodiment, the first connecting shaft 11 and the second connecting shaft 12 are arranged on the left side of the fence 1, and the first connecting shaft 11 and the second connecting shaft 12 are also arranged on the right side of the fence 1. Among them, the first connecting shaft 11 and the second connecting shaft 12 on the left side of the fence 1 are used to pass through the installation cavity 201 of the first guide rail 2a, and the first connecting shaft 11 and the second connecting shaft 12 on the right side of the fence 1 are used to pass through the installation cavity 201 of the second guide rail 2b.

[0058] Furthermore, when the first connecting shaft 11 and the second connecting shaft 12 move from the first stroke to the second stroke, the elastic locking structure 3 undergoes elastic deformation and elastically abuts the first connecting shaft 11 and the second connecting shaft 12 against the inside of the installation cavity 201.

[0059] It should be understood that when the first connecting shaft 11 and the second connecting shaft 12 switch from the first stroke to the second stroke, the first connecting shaft 11 and the second connecting shaft 12 abut against the elastic locking structure 3, causing it to undergo elastic deformation, such as elastic contraction, and then relying on the elastic deformation recovery ability of the elastic locking structure 3 to abut the first connecting shaft 11 and the second connecting shaft 12 against the inside of the installation cavity 201 so that they cannot leave the installation cavity 201 without external force; if the fence 1 needs to be disassembled, only by applying an external force greater than the deformation recovery force of the elastic locking structure 3 can the first connecting shaft 11 and the second connecting shaft 12 be disengaged from the fixation of the elastic locking structure 3, thereby realizing the detachable connection between the fence 1 and the first guide rail 2a and the second guide rail 2b.

[0060] Combined Figure 5 and Figure 6 As shown, both the first guide rail 2a and the second guide rail 2b are provided with a first through hole 202 and a second through hole 203 communicating with the installation cavity 201. The first through hole 202 and the second through hole 203 are arranged at intervals. The first connecting shaft 11 passes through the installation cavity 201 from the first through hole 202, and the second connecting shaft 12 passes through the installation cavity 201 from the second through hole 203.

[0061] In this embodiment, the first via hole 202 is in an "L" shape, that is, the first via hole 202 includes a first vertical hole section 202a and a first horizontal hole section 202b. The first connecting shaft 11 performs a first stroke movement within the first vertical hole section 202a and a second stroke movement within the first horizontal hole section 202b.

[0062] It should be understood that when the first connecting shaft 11 moves within the first horizontal hole section 202b, it presses against the elastic locking structure 3, causing elastic deformation, and the elastic locking structure 3 can elastically abut the first connecting shaft 11 against the hole wall of the first horizontal hole section along the axial direction of the first vertical hole section 202a.

[0063] In this embodiment, the second via hole 203 is in an "L" shape, that is, the second via hole 203 includes a second vertical hole section 203a and a second horizontal hole section 203b. The second connecting shaft 12 performs a first stroke movement within the second vertical hole section 203a and a second stroke movement within the second horizontal hole section 203b; wherein, when the second connecting shaft 12 moves within the second horizontal hole section 203b, it presses against the elastic locking structure 3, causing elastic deformation, and the elastic locking structure 3 can elastically abut the second connecting shaft 12 against the hole wall of the second horizontal hole section along the axial direction of the second vertical hole section 203a.

[0064] In this embodiment, the first via hole 202 and the second via hole 203 on the first guide rail 2a are axisymmetric about the center of the first guide rail 2a; the first via hole 202 and the second via hole 203 on the second guide rail 2b are axisymmetric about the center of the first guide rail 2a.

[0065] In this embodiment, both the first guide rail 2a and the second guide rail 2b include an inner side plate and an outer side plate arranged oppositely, as well as a top plate and a bottom plate arranged oppositely. The inner side plate and the outer side plate are connected between the top plate and the bottom plate and enclose an installation cavity 201; wherein, the first vertical hole section 202a, the second vertical hole section 203a, the first horizontal hole section 202b, and the second horizontal hole section 203b are arranged on the inner side plate.

[0066] Furthermore, the first via hole 202 further includes a first avoidance hole section 202c for avoiding the first connecting shaft 11, and the second via hole 203 further includes a second avoidance hole section 203c for avoiding the second connecting shaft 12. The first avoidance section and the second avoidance section are arranged on the top plate.

[0067] It should be understood that when the distance between the first guide rail 2a and the second guide rail 2b is equal to the distance between two opposite sides of the fence 1 for setting the first connecting shaft 11 and the second connecting shaft 12, the first connecting shaft 11 can extend into the first vertical hole section 202a through the first avoidance hole section 202c; the second connecting shaft 12 can extend into the second vertical hole section 203a through the second avoidance hole section 203c.

[0068] Combined Figure 1 、 Figures 7 to 9 As shown, the elastic locking structure 3 includes a first locking member 31, a second locking member 32, a positioning member 33, a torsion spring 34, a first fixing member 35, and a second fixing member 36. For example, the positioning member 33, the first fixing member 35, and the second fixing member 36 can all be rivets.

[0069] In this embodiment, the first guide rail 2a is connected to the fence 1 through an elastic locking structure 3, and the second guide rail 2b can also be connected to the fence 1 through another elastic locking structure 3, and the elastic locking structures 3 are all the same.

[0070] Combined Figures 1 to 9 As shown, the first fixing member 35 passes through one end of the first locking member 31 and is fixed to the cavity wall of the installation cavity 201; the second fixing member 36 passes through one end of the second locking member 32 and is fixed to the cavity wall of the installation cavity 201.

[0071] In this embodiment, the first fixing member 35 and the second locking member 32 are arranged at intervals, that is to say, the first fixing member 35 does not fix the second locking member 32. The second fixing member 36 and the first locking member 31 are arranged at intervals, that is to say, the second fixing member 36 does not fix the first locking member 31.

[0072] Combined Figure 7 and Figure 9 As shown, the positioning member 33 is located between the first fixing member 35 and the second fixing member 36, and sequentially passes through the first locking member 31, the torsion spring 34, and the second locking member 32.

[0073] In this embodiment, the positioning member 33 passes through the middle position of the first locking member 31 and the second locking member 32, and the first fixing member 35 and the second fixing member 36 are respectively located on both sides of the positioning member 33.

[0074] It should be understood that the positioning member 33 is not connected to the cavity wall of the installation cavity 201 to avoid interfering with the rotation of the first locking member 31 and the second locking member 32.

[0075] Combined Figure 7 and Figure 9 As shown, one end of the torsion spring 34 is connected to the first locking member 31, and the other end of the torsion spring 34 is connected to the second locking member 32.

[0076] In this embodiment, one end of the first locking member 31 is arranged opposite to the first horizontal and vertical hole section 202b, and when the first connecting shaft 11 moves from the first vertical hole section 202a to the first horizontal and vertical hole section 202b, it rotates, and the torsion spring 34 is synchronously elastically deformed.

[0077] It should be understood that when the first connecting shaft 11 moves within the first horizontal straight hole section 202b, one end of the first locking member 31 corresponding to the first connecting shaft 11 is pressed downward and moves, causing the torsion spring 34 to undergo elastic deformation synchronously. After the torsion spring 34 undergoes elastic deformation, the elastic deformation restoring force generated causes the first locking member 31 to push upward, thereby elastically pressing the first connecting shaft 11 against the hole wall of the first horizontal straight hole section 202b to fix it.

[0078] Further, one end of the second locking member 32 is disposed opposite to the second horizontal straight hole section 203b, and rotates when the second connecting shaft 12 moves from the second vertical hole section 203a to the second horizontal straight hole section 203b, causing the torsion spring 34 to undergo elastic deformation synchronously.

[0079] It should be understood that when the second connecting shaft 12 moves within the second horizontal straight hole section 203b, one end of the second locking member 32 corresponding to the second connecting shaft 12 is pressed downward and moves, causing the torsion spring 34 to undergo elastic deformation synchronously. After the torsion spring 34 undergoes elastic deformation, the elastic deformation restoring force generated causes the second locking member 32 to push upward, thereby elastically pressing the second connecting shaft 12 against the hole wall of the second horizontal straight hole section 203b to fix it.

[0080] Combined Figure 7 and Figure 8 As shown, a first groove 301 is provided on the first locking member 31. The first groove 301 is disposed opposite to the first horizontal straight hole section 202b and is used to limit the first connecting shaft 11.

[0081] It should be understood that when the first connecting shaft 11 moves within the first horizontal straight hole in a direction away from the first vertical hole and into the first groove 301 of the first locking member 31, the torsion spring 34 at least recovers part of the elastic deformation force, further causing the first connecting shaft 11 to be unable to move back toward the first vertical hole section 202a along the first horizontal straight hole section 202b without external force.

[0082] Combined Figure 7 and Figure 8 As shown, a second groove 302 is provided on the second locking member 32. The second groove 302 is disposed opposite to the second horizontal straight hole section 203b and is used to limit the second connecting shaft 12.

[0083] It should be understood that when the second connecting shaft 12 moves within the second horizontal straight hole in a direction away from the second vertical hole and into the second groove 302 of the second locking member 32, the torsion spring 34 at least recovers part of the elastic deformation force, further causing the second connecting shaft 12 to be unable to move back toward the second vertical hole section 203a along the second horizontal straight hole section 203b without external force.

[0084] Combined Figure 1 and Figure 10As shown, the guardrail assembly further includes a support member 4. The support member 4 is connected between the fence 1 and the first guide rail 2a and / or the second guide rail 2b, and is used to adjust the flipping angle of the fence 1.

[0085] In this embodiment, the fence 1 is connected to the first guide rail 2a through a support member 4, and the fence 1 is connected to the second guide rail 2b through another support member 4.

[0086] Further, a plurality of adjustment holes 401 are provided on the support member 4, and the plurality of adjustment holes 401 are spaced from each other; a plurality of connecting columns 21 are provided on the corresponding first guide rail 2a and the second guide rail 2b, and a fixed shaft 13 can also be provided between the first connecting shaft 11 and the second connecting shaft 12 of the fence 1. One end of the support member 4 can be connected to the fixed shaft 13 through one of the plurality of adjustment holes 401, and the other end of the support member 4 can be connected to the connecting column 21 through another adjustment hole 401 among the plurality of adjustment holes 401, so as to further fix the flipped fence 1 through the support member 4. Among them, the plurality of adjustment holes 401 are connected to different connecting columns 21, and the angles of the fence 1 during use are also different.

[0087] Combined Figure 1 and Figure 10 As shown, the guardrail assembly further includes a first limiting member 5a and a second limiting member 5b for connecting the cargo box 6. The first limiting member 5a is provided with a first sliding groove 501, and the second limiting member 5b is provided with a second sliding groove.

[0088] Further, the first guide rail 2a is installed in the first sliding groove 501 and can slide in the first sliding groove 501, and the second guide rail 2b is installed in the second sliding groove and can slide in the second sliding groove. Therefore, by changing the position of the first guide rail 2a in the first sliding groove 501 and the position of the second guide rail 2b in the second sliding groove, the position of the fence 1 can be changed according to the user's needs. Among them, the groove wall of the second sliding groove can also limit the movement of the fence 1 in the left-right direction.

[0089] Further, a plurality of first positioning grooves 501a are spaced in the first sliding groove 501, and a plurality of second positioning grooves are spaced in the second sliding groove; the first guide rail 2a is provided with first protrusions at intervals, and the first protrusions can be installed in one of the plurality of first positioning grooves 501a, so as to be able to fix the first guide rail 2a after adjusting the position; the second guide rail 2b is provided with second protrusions at intervals, and the second protrusions can be installed in one of the plurality of second positioning grooves, so as to be able to fix the second guide rail 2b after adjusting the position.

[0090] In summary, in this embodiment, the guardrail assembly passes the first connecting shaft 11 through the installation cavity 201 and elastically abuts against the inside of the installation cavity 201 through the elastic locking structure 3. The second connecting shaft 12 is disengaged from the installation cavity 201. After the fence 1 is flipped to the angle required by the user (for example, the fence 1 can be flipped to a state where it can prevent the goods from rolling over and smashing the rear windshield and injuring the cab members), the fence 1, the first guide rail 2a, and the second guide rail 2b are fixed into a whole through the support member 4; alternatively, according to the usage requirements, the guardrail assembly can also assemble multiple fences 1 with the first guide rail 2a and the second guide rail 2b on the corresponding first limiting member 5a and the second limiting member 5b, which can prevent the loaded goods from moving and jumping out of the cargo box 6. At the same time, the use angle of each fence 1 can be adjusted; or, when the vehicle wheels get stuck in a sand pit during driving, the fence 1 can be disassembled and placed under the wheels, which can help the vehicle get out of trouble quickly. Therefore, the usage scenarios of the guardrail assembly of this cargo box 6 can be freely combined according to the user's needs.

[0091] This application also provides a cargo box 6, including a box body and the above-mentioned guardrail assembly, and the guardrail assembly is installed on the box body.
