[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1 to 6 As shown, this embodiment provides a sliding rail structure for a rear luggage compartment, including: a sliding rail assembly 1, which includes a sub-rail portion and a main rail portion. The sub-rail portion is slidably connected to the main rail portion, and the main rail portion is used to connect to the vehicle frame 6.

[0031] In this embodiment, since the sub-rail is slidably connected to the mother rail, the sub-rail can slide relative to the mother rail. Therefore, when the partition in the rear luggage compartment is connected to the sub-rail, the partition and the sub-rail slide synchronously relative to the mother rail, allowing the partition to divide the rear luggage compartment for easy storage of items.

[0032] Furthermore, the sliding rail structure of the rear luggage compartment also includes a mounting bracket 2, which includes a connecting part 21 and a blocking part 22. The connecting part 21 is connected to the blocking part 22. The connecting part 21 is used to connect to the vehicle frame 6. The blocking part 22 is arranged opposite to the sliding rail assembly 1 along the retraction direction x1 of the sub-rail part.

[0033] In this embodiment, a rear partition is provided between the rear luggage compartment and the passenger compartment, which separates the two spaces. The sub-rail section has a retractable direction x1 and an extendable direction x2 that can be switched between each other: when the sub-rail section slides relative to the main rail section along the retractable direction x1, the distance between the partition and the rear partition gradually decreases as the sub-rail section slides; when the sub-rail section slides relative to the main rail section along the extendable direction x2, the distance between the partition and the rear partition gradually increases as the sub-rail section slides.

[0034] It should be understood that the length direction x of the slide rail assembly is parallel to the retraction direction x1 and the extension direction x2 of the sub-rail section. The length direction x of the slide rail assembly is bidirectional; the retraction direction x1 and the extension direction x2 of the sub-rail section are both unidirectional.

[0035] In this embodiment, when the vehicle is rear-ended and the slide rail assembly 1 moves toward the front of the vehicle due to inertia, since the blocking part 22 is arranged opposite to the slide rail assembly 1 along the retraction direction x1 of the sub-rail, the slide rail assembly 1 will first hit the blocking part 22 under the action of inertia. Therefore, the blocking part 22 can prevent the slide rail assembly 1 from intruding into the passenger compartment along the retraction direction x1 of the sub-rail, thereby avoiding injury to the occupants due to the intrusion of the slide rail assembly 1, so as to ensure the safety of the occupants.

[0036] Combination Figure 2 As shown, the slide rail assembly 1 also includes a track section 11 and a deformation section 12. The deformation section 12 is located between the track section 11 and the blocking part 22, and the track section 11 and the deformation section 12 are connected. The sub-rail part and the main rail part are located on the track section 11. The stiffness of the deformation section 12 is less than the stiffness of the track section 11.

[0037] In this embodiment, since the deformation segment 12 is located between the track segment 11 and the blocking part 22, when the vehicle is rear-ended, the deformation segment 12 with less stiffness will collide with the blocking part 22 first compared to the track segment 11 with greater stiffness, so as to avoid the track segment 11 with greater stiffness directly colliding with the blocking part 22, thereby preventing the blocking part 22 from failing.

[0038] It should be understood that track segment 11 has greater stiffness than deformation segment 12. If track segment 11 collides directly with the blocking part 22, the blocking part 22 is at risk of failure. By setting a deformation segment 12 with lower stiffness between track segment 11 and the blocking part 22, the deformation segment 12 can collapse and absorb energy in the event of a rear-end collision, which helps to reduce the impact force on the blocking part 22.

[0039] In this embodiment, the deformation segment 12 is a plastic structure, and the track segment 11 is a metal structure. The stiffness of the plastic structure is less than that of the metal structure, which allows the deformation segment 12 to collapse and absorb energy when the vehicle is rear-ended, thus reducing the impact force on the blocking part 22.

[0040] For example, plastic structures can be made of materials such as polypropylene, polyethylene, and acrylonitrile-butadiene-styrene copolymer. Metal structures can be made of materials such as aluminum alloy and high-strength steel.

[0041] In other embodiments, both track segment 11 and deformation segment 12 are metal structures, with deformation segment 12 being a soft metal structure and track segment 11 being a hard metal structure.

[0042] For example, soft metal structures can be made of materials such as aluminum and aluminum alloys. Hard metal structures can be made of materials such as high-strength steel and stainless steel.

[0043] In this embodiment, combined with Figure 2 and Figure 6 As shown, the deformation section 12 is provided with a deformation cavity 101. The deformation cavity 101 is provided so that when the vehicle is rear-ended and the deformation section 12 collides with the blocking part 22, the deformation section 12 will be squeezed and deformed to absorb energy by collapsing, which helps to reduce the impact force on the blocking part 22.

[0044] In this embodiment, combined with Figure 6 As shown, a first reinforcing rib 3 is provided inside the deformation cavity 101. The first reinforcing rib 3 is connected to the deformation segment 12 and has a mesh structure. The first reinforcing rib 3 can improve the degree of energy absorption by the collapse of the deformation segment 12 and further reduce the impact force on the blocking part 22.

[0045] In this embodiment, the first reinforcing rib 3 includes multiple first reinforcing parts 31 of the same shape and size and multiple second reinforcing parts 32 of the same shape and size. The multiple first reinforcing parts 31 are spaced apart from each other and arranged opposite each other along the length direction x of the slide rail assembly, and the multiple second reinforcing parts 32 are spaced apart from each other and arranged opposite each other along the width direction y of the slide rail assembly. The multiple first reinforcing parts 31 and the multiple second reinforcing parts 32 are connected and intersected, dividing the deformation cavity 101 into several deformation sub-cavities 101a to form a grid structure.

[0046] It should be understood that "multiple" refers to two or more items, such as two, three, etc. The number of the first reinforcing part 31 and the number of the second reinforcing part 32 can be selected according to the actual situation (e.g., the degree of energy absorption required by the deformation section 12).

[0047] For example, the first reinforcing rib 3 may include five first reinforcing parts 31 and two second reinforcing parts 32, and divide the deformation cavity 101 into eighteen deformation sub-cavities 101a.

[0048] Combination Figure 1 and Figure 2As shown, the sliding rail structure of the rear luggage compartment also includes a support part 4, which is connected to the mounting bracket 2 and the sliding rail assembly 1 and is used to support the sliding rail assembly 1; the support part 4 is arranged opposite to the blocking part 22 along the retraction direction x1 of the sub-rail part; the minimum distance between the support part 4 and the blocking part 22 is greater than the minimum distance between the deformation section 12 and the blocking part 22.

[0049] In this embodiment, the support part 4 is bolted to the frame 6 to support the slide rail assembly 1. Since the support part 4 is arranged opposite to the blocking part 22 along the retraction direction x1 of the sub-rail, when the vehicle is rear-ended, the blocking part 22 can prevent the support part 4 from intruding into the passenger compartment along the retraction direction x1 of the sub-rail, thereby avoiding injury to the occupants due to the intrusion of the support part 4 and ensuring the safety of the occupants.

[0050] It should be understood that when a vehicle is involved in a rear-end collision, the bolts connecting the support part 4 and the frame 6 will fail, causing the connection between the support part 4 and the frame 6 to fail. As a result, the support part 4 will move towards the front of the vehicle due to inertia.

[0051] Furthermore, the minimum distance between the support part 4 and the blocking part 22 is greater than the minimum distance between the deformation section 12 and the blocking part 22, so that when the vehicle is rear-ended, the deformation section 12 collides with the blocking part 22 first than the support part 4, and collapses to absorb energy, which helps to reduce the impact force on the blocking part 22.

[0052] Combination Figure 3 and Figure 5 As shown, the support part 4 includes a first support section 41 and a second support section 42. The first support section 41 is located between the second support section 42 and the blocking part 22. The first support section 41 is connected to the second support section 42. The first support section 41 and the deformation section 12 are arranged opposite to each other along the thickness direction z of the slide rail assembly. The second support section 42 and the track section 11 are arranged opposite to each other along the thickness direction z of the slide rail assembly and are connected to the track section 11. A gap 401 is provided between the first support section 41 and the deformation section 12. The first support section 41 includes a plurality of support sub-segments 41a, and the cross-sectional areas of each support sub-segment 41a are not equal.

[0053] In this embodiment, a gap 401 is provided between the first support section 41 and the deformation section 12, so that the first support section 41 and the deformation section 12 are spaced apart, so as to avoid the first support section 41 affecting the collapse of the deformation section 12.

[0054] In this embodiment, the cross-sectional areas of each support segment 41a are not equal, meaning the gaps 401 between each support segment 41a and the deformation segment 12 are not the same. Furthermore, since the end of the second support segment 42 closest to the first support segment 41 is connected to the track segment 11, the cross-sectional area of ​​the end of the second support segment 42 closest to the first support segment 41 is larger than the cross-sectional area of ​​each support segment 41a. Therefore, when the second support segment 42 collides with the blocking part 22, the end of the second support segment 42 closest to the first support segment 41 contacts the blocking part 22 first, and the contact area between the two is larger, which helps to disperse the collision force and thus prevents the second support segment 42 from intruding into the passenger compartment.

[0055] Combination Figure 2 and Figure 3 As shown, the first support section 41 includes a first side plate 411, a second side plate, and a support top plate 412. The first side plate 411 and the second side plate are arranged opposite each other along the width direction y of the slide rail assembly. The support top plate 412 is connected between the first side plate 411 and the second side plate, and the plate surface 412a of the support top plate 412 faces the deformation section 12. The first side plate 411 is provided with a plurality of first collapse grooves 402, which are spaced apart from each other.

[0056] In this embodiment, the mounting bracket 2 is connected to the rear wheel arch 7 of the vehicle, and the first support section 41 is connected to the connecting part 21. Along the width direction y of the slide rail assembly, the first side plate 411 is further away from the rear wheel arch 7 than the second side plate. Since the first side plate 411 is provided with multiple first crumple grooves 402, when the vehicle is rear-ended and the first support section 41 collides with the blocking part 22, the first support section 41 can crumple and deform and absorb a certain amount of energy, which helps to reduce the impact force on the blocking part 22 when it collides with the first support section 41.

[0057] It should be understood that the first support section 41 and the deformation section 12 are spaced apart, which can also prevent the deformation section 12 from affecting the collapse of the first support section 41.

[0058] Furthermore, the supporting top plate 412 is provided with a second crumple groove 403, which is correspondingly provided with a first crumple groove 402 that is closest to the second supporting section 42.

[0059] In this embodiment, combined with Figure 2 and Figure 5As shown, the second crumple zone 403 and the first crumple zone 402 closest to the second support section 42 are both located in the support sub-segment 41a closest to the second support section 42. Through the corresponding arrangement of the second crumple zone 403 and the first crumple zone 402 closest to the second support section 42, when a rear-end collision occurs and the first support section 41 collides with the blocking part 22, the support sub-segment 41a closest to the second support section 42 breaks, separating the first support section 41 from the second support section 42, thereby preventing the second support section 42 from intruding into the passenger compartment.

[0060] It should be understood that since the first support section 41 and the deformation section 12 are arranged opposite each other along the thickness direction z of the slide rail assembly, and the second support section 42 and the track section 11 are arranged opposite each other along the thickness direction z of the slide rail assembly, when the second support section 42 contacts the blocking part 22, the track section 11 may also contact the blocking part 22.

[0061] In this embodiment, combined with Figure 4 As shown, the blocking part 22 is provided with a reinforcing cavity 201, and a second reinforcing rib 5 is provided inside the reinforcing cavity 201. The second reinforcing rib 5 is connected to the blocking part 22 and has a grid structure. The provision of the second reinforcing rib 5 can increase the rigidity of the blocking part 22, thereby helping to reduce the probability of the blocking part 22 failing.

[0062] In this embodiment, the second reinforcing rib 5 includes multiple third reinforcing parts 51 of the same shape and size, and multiple fourth reinforcing parts 52 of the same shape and size. The multiple third reinforcing parts 51 are spaced apart from each other and arranged opposite each other along the thickness direction z of the slide rail assembly, and the multiple fourth reinforcing parts 52 are spaced apart from each other and arranged opposite each other along the length direction x of the slide rail assembly. The multiple third reinforcing parts 51 and the multiple fourth reinforcing parts 52 are connected and intersecting, dividing the reinforcing cavity 201 into several reinforcing sub-cavities 201a to form a grid structure.

[0063] It should be understood that "multiple" refers to two or more items, such as two, three, etc. The number of third reinforcing parts 51 and the number of third reinforcing parts 51 can be selected according to the actual situation (e.g., the magnitude of the rigidity that the blocking part 22 needs to be enhanced).

[0064] For example, the second reinforcing rib 5 may include two third reinforcing parts 51 and two fourth reinforcing parts 52, and divide the reinforcing cavity 201 into nine reinforcing sub-cavities 201a.

[0065] In this embodiment, when a rear-end collision occurs, the deformation segment 12 first contacts the blocking part 22 and collapses to absorb energy. Then, the first support segment 41 contacts the blocking part 22 and collapses to absorb energy. Next, as the first support segment 41 and the deformation segment 12 collapse, the first support segment 41 and the second support segment 42 break apart at the support sub-segment 41a closest to the second support segment 42, and the deformation segment 12 collapses completely. Finally, the track segment 11 and the second support segment 42 simultaneously contact the blocking part 22, increasing the contact area and further preventing the track segment 11 and the second support segment 42 from intruding into the passenger compartment. Only a small portion of the collision force is transmitted to the passenger compartment.

[0066] In summary, the sliding rail structure of the rear luggage compartment can meet the requirements of a high-speed rear collision at 90 km / h, preventing the sliding rail assembly 1 and the support part 4 from intruding into the passenger compartment, thereby preventing injury to the occupants.

[0067] This embodiment also provides a vehicle, including a frame 6 and the aforementioned sliding rail structure for the rear luggage compartment, the sliding rail structure for the rear luggage compartment being connected to the frame 6.

[0068] In this embodiment, the vehicle includes two rear luggage compartment slide rail structures, which are arranged opposite to each other and symmetrically along the wheel track direction of the vehicle (along the width direction y of the slide rail assembly).
