Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. Although the present embodiment is described by taking an example in which the partition device is provided in the opening at the front end of the rear crash box body, the partition device is also applicable to the opening at the rear end of the rear crash box body or other locations of the vehicle, such as a rocker beam, that require sealing.

As used herein, directional terms such as "front", "rear", and "rear", etc., are all with reference to the fore-aft direction of the vehicle after the component is mounted to the vehicle. The terms "longitudinal", "longitudinal" and "longitudinal section" are used herein with reference to the front-rear direction of the component after it is mounted to the vehicle, while "lateral", "transverse" and "cross-section" refer to directions perpendicular to the longitudinal direction. The "inner" and "outer" are referred to herein with reference to the vehicle compartment, i.e., the side closer to the occupant is the inner side and the side closer to the outside of the vehicle is the outer side. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

At present, in order to reduce the weight of the whole vehicle and facilitate energy absorption, a rear anti-collision box is generally arranged to be of a structure with a cavity. The end of the rear anti-collision box is provided with an opening, a plurality of process holes or mounting holes are formed in the rear anti-collision box, and the rear anti-collision box is communicated with the luggage compartment through the mounting holes/the process holes. During driving, air flows in these cavities, which tends to generate undesirable wind noise. When the wading waterway surface is involved, external water enters the luggage compartment through the opening and the fabrication holes or the mounting holes in sequence, and the poured water also shakes and makes abnormal sound in the cavity, so that the experience of passengers is very poor. At present, the blocking structure is usually arranged at the opening to avoid the generation of unexpected wind noise and the water from the outside entering the luggage compartment. The blocking structure usually includes a foaming material, such as EVA (Ethylene Vinyl Acetate Copolymer), etc., and after the blocking structure is mounted to the end of the rear crash box, the EVA is bonded to the inner wall of the rear crash box by means of microcellular foaming when being baked, so as to achieve the purpose of blocking the opening. However, due to the influence of baking temperature change, the interface effect of the inner wall of the rear anti-collision box and the surface cleanliness of the inner wall, a small number of thin tubular through holes are generated with probability in the baking process, and therefore the waterproof performance of the plugging structure is not ideal under the working conditions of deep wading and water immersion. Therefore, the utility model discloses a first side of wall body of off device is provided with first muscle position, cuts off the outside that the piece is located this first muscle position, encloses between the inner wall of this first muscle position and back anticollision box and establishes an annular crack of formation, when toasting, can guide through this first muscle position to cut off the piece at first along the abundant foaming all around of first muscle position, fully foam along annular crack promptly to ensure the sealed effect of its circumference. After the partition piece is fully foamed along the circumferential direction, the partition piece crosses the first rib position to foam towards the middle of the first rib position, so that the whole opening is sealed, and a good sealing effect is obtained.

First, a possible implementation of the partition device of the present invention is described with reference to fig. 1 to 10 in combination with a rear crash box assembly.

As shown in fig. 1 to 4, the rear anti-collision box assembly includes a rear anti-collision box body 2, the rear anti-collision box body 2 is a hollow structure penetrating from front to back, the rear anti-collision box body 2 is matched with the rear longitudinal beam 1, and openings 21 are arranged at both ends of the rear anti-collision box body. According to the advancing direction of the vehicle (as shown in fig. 1, the right side is the tail direction of the vehicle, and the left side is the head direction of the vehicle), the front end of the rear anti-collision box body 2 (i.e. the first end of the rear anti-collision box body 2) is the indirect upstream surface, and the rear end of the rear anti-collision box body 2 is the upstream surface. The opening 21 of the rear end (namely the second end of the rear anti-collision box body 2) of the rear anti-collision box body 2 is abutted against the rear wall outer plate 3 and is blocked by the rear wall outer plate 3, the peripheral side of the front end of the rear anti-collision box body 2 is abutted against the rear end of the rear longitudinal beam 1 in a matching manner, and one fifth of the opening 21 of the front end of the rear anti-collision box body 2 is not blocked by the rear longitudinal beam 1. Thus, when the vehicle runs through a wading road surface, particularly when the water accumulated on the road surface is deep, the external water mainly enters the rear anti-collision box body 2 through one fifth of the exposed part of the opening 21 at the front end of the rear anti-collision box body 2. Then be provided with a plurality of through-holes 23 with the inside intercommunication in carriage on the crashproof box body 2, these through-holes 23 can be fabrication hole or mounting hole, and the water in the crashproof box body 2 will enter into inside the carriage after like this. The rear crash box assembly disclosed in this application improves upon these issues one by one.

As shown in fig. 1 to 5, the rear crash box assembly further includes a partition device 4, in order to prevent water from entering the interior of the vehicle compartment through the through holes 23, the partition device 4 is disposed at the opening 21 at the front end of the rear crash box body 2 in the present application, so that the opening 21 can be filled and blocked, and unexpected wind noise is prevented from being generated during driving, or external water enters the interior of the vehicle compartment (i.e., the luggage compartment) through the opening, thereby improving the experience of passengers. For the sake of convenience of explanation, the openings 21 described below each represent an opening 21 at the front end of the rear crash box body 2.

As shown in fig. 3, 6, 8 and 10, the partition device 4 includes a partition body 41 and a partition member 42, and the partition body 41 and the partition member 42 are formed by two-shot or two-shot injection molding.

The partition member 42 is formed on a first side (i.e., a side facing the opening 21) of the partition body 41, and the partition member 42 and the partition body 41 have substantially the same outer shape, size, and the like. During assembly, the partition device 4 is inserted into the opening 21 of the rear crash box body 2 in an inserting manner, so that the opening 21 can be blocked. The partition 42 is typically a foam material such as EVA or the like. After the partition device 4 is attached to the opening 21, the partition member 42 is changed during the paint baking, and foams and expands, so that the opening 21 can be closed better.

As shown in fig. 3 to 6, 8, and 10, the partition body 41 and the partition 42 are each roughly divided into an upper portion and a lower portion in the vehicle height direction, and the opening 21 is roughly of a zigzag structure. When assembled, the upper portions of the partition body 41 and the partition 42 are fitted to the upper portion of the opening 21, and the lower portions of the partition body 41 and the partition 42 are fitted to the lower portion of the opening 21, so that the opening 21 can be closed better.

As shown in fig. 6 to 8 and 10, the first side of the partition body 41 of the present invention is provided with a first rib position 411 along the circumferential direction, and the first rib position 411 extends toward the inside of the opening 21 along the direction away from the first side of the partition body 41, and is substantially an annular rib with a rounded trapezoid structure. Obviously, the first rib position 411 may also be configured as an annular rib with an oval structure, a rectangular structure, or the like. Obviously, the first rib position 411 may also be configured as a non-annular rib, for example, the first rib position 411 is formed by a plurality of strip ribs arranged at intervals, and the like, and those skilled in the art can flexibly select the rib position according to a specific application scenario.

The partition member 42 is formed on the circumferential outer side of the first rib position 411, so that when baking is performed, the partition member 42 is guided by the first rib position 411 to be foamed fully along the periphery of the first rib position 411, and the sealing effect between the circumferential direction of the partition body 41 and the rear anti-collision box body 2 is ensured. After the partition member 42 is fully foamed along the circumferential direction, the foam crosses the first rib position 411 to foam towards the middle of the first rib position 411, so that the whole opening 21 is blocked, a good filling and sealing effect is obtained, and the experience of passengers is further improved. In addition, the first rib portions 411 can also enhance the strength of the partition body 41, so that the partition body 41 is not easily deformed, and the opening 21 can be more stably closed.

As shown in fig. 2, 5 to 8 and 10, the second side of the partition body 41 is recessed toward the first side of the partition body 41 (i.e., is recessed inward from the outer side of the partition body 41 in fig. 2) to form a sink 412, and in order to ensure the uniformity of thickness of the partition body 41 at all places and to ensure the feasibility of the injection molding process, the sink 412 is correspondingly formed with a boss 413 on the first side of the partition body 41, and the boss 413 is substantially in a shape of a rounded trapezoid. Obviously, the outer shape of the boss 413 may also be an oval shape, a rectangular shape, or the like. Obviously, the second side of the partition body 41 may not be provided with the sink 412, and the first side of the partition body 41 may not be formed with the boss 413.

The first rib 411 is disposed on the boss 413, and the partition 42 is formed around the boss 413 in a substantially annular shape. By providing the boss 413, the partition member 42 can be uniformly molded around the boss 413 during molding, so that the thickness uniformity of the partition member 42 at each position is ensured, and the partition member 42 can be molded on the first side of the partition body 41 better. And the partition piece 42 with uniform thickness is also beneficial to the partition piece 42 to be uniformly foamed along the periphery of the first rib position 411 during baking, so that the sealing effect between the circumferential direction of the partition body 41 and the rear anti-collision box body 2 can be better ensured.

In a possible implementation, in order to further promote the sealing effect of the rear crash box body 2, the utility model discloses a plurality of through-holes 23 on the rear crash box body 2 are provided with sealing members, such as sealing patches, sealing tapes, etc. so as to block these a plurality of through-holes 23 through this sealing member, thereby obtain better sealing effect.

As shown in fig. 2 and 5 to 10, the partition device 4 further includes a clamp 43, and the clamp 43 is made of a metal material such as a 65Mn black paint or a stainless steel material.

As shown in fig. 1, 3, and 7, in order to reinforce the strength of the rear crash box body 2, a support rib is provided in the rear crash box body 2, and the end of the support rib forms the attachment portion 22.

As shown in fig. 2, 6, 8 and 9, two first recessed portions 415 are formed at a first side of the partition body 41 and recessed toward a second side thereof (i.e., the partition body 41 is recessed from the inside to the outside in fig. 2) substantially at a middle portion thereof, and two first fastening holes 414 are respectively formed in the two first recessed portions 415. Through the setting of first depressed part 415, compare with not setting up first depressed part 415, can make the centre gripping point of anchor clamps 43 on installation department 22 deepen more in back anticollision box body 2 to drive off device 4 and remove towards installation department 22, thereby after installing off device 4 to the opening 21 department of back anticollision box body 2 through anchor clamps 43, can make off device 4 sink in the back anticollision box body 2.

Obviously, instead of providing the first recessed portion 415, the end portion of the support rib formed with the mounting portion 22 may be moved toward the inside of the rear crash box body 2, so that the clamping point of the clamp 43 on the mounting portion 22 can be made deeper into the rear crash box body 2, and the partition device 4 can be made to sink toward the rear crash box body 2. Those skilled in the art can flexibly select the partition device according to a specific application scenario as long as the partition device 4 can sink into the rear anti-collision box body 2.

With continued reference to fig. 2, 6, 8 and 9, the interior of the first recess 415 is recessed toward the second side of the partition body 41 (i.e., the first recess 415 is recessed from the inside to the outside in fig. 2) to form a second recess 416, the second recess 416 includes a transverse portion 4161 and vertical portions 4162 at both ends of the transverse portion 4161, a substantially "i" shaped structure is formed by the transverse portion 4161 and the two vertical portions 4162, and the transverse portion 4161 of the second recess 416 is located in the jig 43 in a state where the partition device 4 is mounted to the opening 21. With this arrangement, the clamping point of the jig 43 on the mounting portion 22 is further increased than when the second recessed portion 416 is not provided, and the partition device 4 can be more favorably sunk into the rear crash box body 2 after the partition device 4 is mounted to the opening 21 of the rear crash box body 2 by the jig 43.

Obviously, this second depressed part 416 can also set up to other structures such as style of calligraphy, under the prerequisite of the principle of the utility model, this second depressed part 416's specific structure can be selected in a flexible way according to specific application scene to the technical staff in the field, as long as can further make off device 4 sink, firmly set up on crashproof box body 2 of back to crashproof box body 2 of back in can.

It is clear that the second recess 416 may not be provided, and that the person skilled in the art may also sink the partition means 4 inwards in other ways, such as by reducing the thickness of the partition body 41 at the location corresponding to the first recess 415, etc.

In order to secure the stability of the partition body 41, the partition body 41 needs to have a sufficient thickness, and for this reason, as shown in fig. 2, 5 and 10, the second side (i.e., the outer side in fig. 2) of the partition body 41 protrudes outward at positions corresponding to the first and second recesses 415 and 416. Typically, the thickness of the partition body 41 is approximately 1-3mm throughout. Preferably, the thickness of the partition body 41 is 2mm throughout. The thickness of the partition body 41 at the position of the first recessed portion 415 is also approximately 2mm, so that the strength of the partition body 41 at the position where the clip 43 is caught can be ensured.

In order to ensure that the clamping point of the clamp 43 on the mounting portion 22 is sufficiently deep into the rear crash box body 2, the thickness of the partition body 41 at the position of the second recessed portion 416 is slightly thinner than the thickness of the partition body 41 at other positions, approximately 0.5-2.5 mm. Preferably, the partition body 41 has a thickness of 1.5mm at a position corresponding to the second recess 416.

With the above arrangement, on the basis of ensuring the strength of the partition body 41, the clamping point of the clamp 43 on the mounting portion 22 can be ensured to be deep enough into the rear crash box body 2, so that the partition device 4 can be better arranged on the rear crash box body 2.

As shown in fig. 1, 2, 8 and 9, the front end of the rear crash box body 2 is fitted to the rear end of the rear side member 1 in the forward direction of the vehicle, and the gap remaining between the two end surfaces is very small, approximately 2 mm. The partition device 4 is mounted at the opening 21 at the front end of the rear crash box body 2, and if the gap between the outer side of the partition device 4 and the rear side member 1 is too small, the outer side of the partition device 4 and the rear side member 1 interfere with each other. Therefore, the first recessed portion 415 and the second recessed portion 416 are provided, so that after the partition device 4 is mounted to the opening 21 of the rear crash box body 2 through the jig 43, the partition device 4 can be sunk into the rear crash box body 2, and thus, the interference caused by the excessively small gap between the outer side of the partition device 4 and the rear side member 1 can be effectively avoided.

As shown in fig. 3 and 7, the clamp 43 is formed by integrally bending a plate body (e.g., spring steel), and includes a first plate section 431, a second plate section 432, a third plate section 433, a fourth plate section 434, and a fifth plate section 435 which are connected in sequence, wherein a distance between the first plate section 431 and the fifth plate section 435 gradually increases along a direction in which the clamp 43 is clamped (i.e., from front to back along the length direction of the vehicle body), and a distance between the second plate section 432 and the fourth plate section 434 gradually decreases along the direction in which the clamp 43 is clamped (i.e., from front to back along the length direction of the vehicle body). The distance between a first junction of the first and second plate sections 431, 432 and a second junction of the fourth and fifth plate sections 434, 435, which form a clamping portion of the clamp 43, is minimal, and the clamp 43 is clamped to the mounting portion 22 by the clamping portion. When assembled, the free ends of the first and fifth plate sections 431 and 435 are aligned with the first fastening holes 414, and then extend into the first fastening holes 414 and pass through the second fastening holes 421, thereby mounting the partition device 4 to the mounting portion 22. When assembled, the third plate segment 433 is located outside the partition body 41, a portion of the second plate segment 432 close to the third plate segment 433, a portion of the fourth plate segment 434 close to the third plate segment 433 are clamped in the first clamping hole 414 and the second clamping hole 421, and the mounting portion 22 is located between the first junction and the second junction, so that the partition device 4 is mounted at the opening 21.

Obviously, the clamp 43 may be provided in other forms, and those skilled in the art may flexibly select the clamp according to the specific application, as long as the partition body 41 and the partition 42 can be installed at the opening 21 by snapping. Obviously, the partition device 4 may also be mounted to the end of the rear crash box body 2 by means of plugging, screwing, or the like.

The utility model discloses a cut-off device 4 is owing to be provided with first muscle position 411 to when anchor clamps 43 are not strutted or are strutted a little, the free end of the first plate section 431 of anchor clamps 43 and fifth plate section 435 just leveled mutually with the tip of first muscle position 411, anchor clamps 43 just so can not strutted too much yet, thereby ensured anchor clamps 43's clamping-force, can install the tip of back anticollision box body 2 with cut-off device 4 more firmly through this anchor clamps 43.

In one possible embodiment, when assembled, the outer circumference of the clamp 43 has a first clearance with the inner wall of the first clamping hole 414, for example, the first clearance is 0.5 mm. This is because it is easier for the operator to pass the clip 43 through the first and second clip holes 414 and 421 and to mount the partition body 41 and the partition member 42 at the opening 21, and if the first gap is not present or is too small, it may cause difficulty in passing the clip 43 through the first and second clip holes 414 and 421. During the later baking, the partition member 42 (e.g. the portion corresponding to the first recess 415 and the second recess 416) around the second card hole 421 will expand due to foaming under heat, and close the first gap, so as to ensure the sealing effect of the partition device 4.

Certainly, the value of this first clearance also can not be too big, if too big, can lead to being located the wall piece 42 around second card hole 421 and can not block up this first clearance completely when the foaming inflation that is heated, and then lead to the sealed effect of wall device 4 not good, or the wall piece 42 foaming inflation to the outside of back anticollision box body 2, influence the planarization of back anticollision box subassembly outward appearance. Obviously, the specific value of the first gap is only described as an example, and a person skilled in the art may flexibly select a specific value of the first gap according to a specific application scenario, for example, the value range of the first gap may be 0.25-1.0mm, as long as the sealing effect and the assembly of the partition device 4 are not affected.

As shown in fig. 5 to 8 and 10, 8 anti-turnover ribs 417 are inwardly disposed on the outer edge of the partition body 41, and the 8 anti-turnover ribs 417 are distributed along the circumferential direction of the partition body 41. Taking the anti-roll rib 417 positioned on the upper side of the partition body 41 in fig. 6 as an example, the anti-roll rib 417 is a substantially cylindrical structure with a plane on the upper side and an arc on the lower side, and the upper side of the anti-roll rib 417 is slightly higher than the outer edge of the partition body 41. In the assembled state, the lower side surface of the anti-turnover rib 417 is located above the partition 42.

Meanwhile, if the rotation occurs, the partial gap between the partition device 4 and the inner wall of the rear anti-collision box body 2 is increased, and when the coating is baked, the partition piece 42 may be foamed and expanded to the outer side of the rear anti-collision box body 2, so that the appearance smoothness of the rear anti-collision box body 2 is affected.

Obviously, the anti-overturn ribs 417 may be configured in other forms, such as plate ribs, column ribs, etc., and those skilled in the art may flexibly select the anti-overturn ribs according to specific application scenarios.

In one possible embodiment, the anti-overturn rib 417 is configured to have a second clearance with the inner wall of the opening 21 when assembled, for example, the second clearance is 0.5 mm. This is to make it easier for the operator to mount the partition body 41 to the mounting portion 22. If the second gap is not provided or is too small, it may be difficult to attach the partition body 41 to the attachment portion 22. When the baking is performed in the later stage, the partition member 42 located outside the first rib position 411 is heated to foam and expand, and the second gap is blocked, so that the sealing effect of the partition device 4 is ensured.

Of course, the value of the second gap cannot be too large, and if the value is too large, the sealing effect of the partition device 4 may be poor, or the partition member 42 may foam and expand to the outside of the rear crash box body 2, which may affect the flatness of the appearance of the rear crash box assembly. Obviously, the specific value of the second gap is only described as an example, and a person skilled in the art may flexibly select a specific value of the second gap according to a specific application scenario, for example, the value range of the second gap may be 0.25-1.0mm, as long as the sealing effect and the assembly of the partition device 4 are not affected.
