When the vehicle is subjected to a collision along its own width direction, both the first collapse chamber and the second collapse chamber can collapse, thereby absorbing the energy generated by the collision and reducing the damage caused by the collision to the occupants of the vehicle. At the same time, the collapse of the first and second collapse chambers will cause the threshold beam to deform and invade the cabin space of the vehicle. If the collision causes the threshold beam to invade the cabin space too much, it may cause difficulty for the occupants to escape. Therefore, in this solution, the thickness of the first side wall of the first collapse chamber near the battery installation portion is set to be greater than the thickness of the second side wall of the second collapse chamber near the battery installation portion, so that the first beam body has stronger rigidity than the second beam body. The first beam body can transmit the collision force to the battery installation portion and the battery unit, and disperse the collision force to the energy absorption structure in the battery unit, thereby reducing the deformation of the first beam body, and also reducing the intrusion amount of the threshold beam into the vehicle cabin space during the collision, thereby reducing the damage caused to the occupants and increasing the probability of escape of the occupants. On the other hand, the second beam body is close to the ground and cannot transmit the collision force to the battery unit. Therefore, the second side wall of the second collapse chamber is set to be thinner, which can reduce the weight of the threshold beam and is conducive to the lightweight of the vehicle.

The utility model provides a threshold beam.

Referring to FIG. 1 , FIG. 1 is a cross-sectional view of a partial structure of a vehicle of the present invention.

In an embodiment of the utility model, the sill beam is applied to a vehicle, comprising:

A battery mounting portion 401 for mounting a battery unit 1000 of a vehicle;

The first beam body 100 is provided with a first collapse cavity 110, the first collapse cavity 110 has a first side wall 101 close to the battery mounting portion 401 and extending in the vertical direction, and the battery mounting portion 401 is provided at one side of the first beam body 100; and

The second beam body 200 is arranged on the ground side of the first beam body 100. The second beam body 200 is provided with a second collapse cavity 210. The second collapse cavity 210 has a second side wall 201 close to the battery mounting portion 401 and extending vertically. The thickness of the first side wall 101 is greater than the thickness of the second side wall 201.

A threshold beam in a technical solution of an embodiment of the utility model includes a first beam body 100, a second beam body 200 and a battery mounting portion 401, the battery mounting portion 401 is arranged on one side of the first beam body 100, the battery unit 1000 of the vehicle is fixed on the battery mounting portion 401, a first collapse chamber 110 is provided on the first beam body 100, the second beam body 200 is arranged on the side of the first beam body 100 facing the ground, and a second collapse chamber 210 is provided on the second beam body 200. When the vehicle is hit along its width direction, the first collapse chamber 110 and the second collapse chamber 210 can both collapse, thereby absorbing the energy generated by the collision and reducing the damage caused by the collision to the occupants of the vehicle. At the same time, the collapse of the first collapse chamber 110 and the second collapse chamber 210 will cause the door sill beam to deform and invade the vehicle's cabin space. If the collision causes the door sill beam to invade the cabin space too much, it may make it difficult for the occupants to escape. Therefore, in this solution, the thickness of the first side wall 101 of the first collapse chamber 110 close to the battery mounting portion 401 is set to be greater than the thickness of the second side wall 201 of the second collapse chamber 210 close to the battery mounting portion 401, so that the first beam body 100 has stronger rigidity than the second beam body 200. The first beam body 100 can transmit the collision force to the battery mounting portion 401 and the battery unit 1000, and disperse the collision force to the energy absorption structure in the battery unit 1000, thereby reducing the deformation of the first beam body 100, and thus reducing the intrusion of the door sill beam into the vehicle cabin space during the collision, thereby reducing the damage to the occupants and increasing the probability of escape of the occupants. On the other hand, the second beam body 200 is close to the ground and cannot transmit the collision force to the battery unit 1000. Therefore, the second side wall 201 of the second collapse chamber 210 is set to have a thinner wall thickness, which can reduce the weight of the sill beam and contribute to the lightweight of the vehicle.

Optionally, the second side wall 201 and the first side wall 101 are arranged adjacent to each other in the vertical direction.

Please refer to Figure 1. In this embodiment, the second side wall 201 and the first side wall 101 are arranged adjacent to each other in the vertical direction. Specifically in this embodiment, the entire threshold beam is integrally formed by aluminum extrusion. The side of the second side wall 201 facing the battery cell 1000 is flush with the side of the first side wall 101 facing the battery cell 1000. The thickness difference between the second side wall 201 and the first side wall 101 can be achieved by changing the volume size of the first collapse cavity 110 and the second collapse cavity 210, and the manufacturing difficulty is low.

Optionally, the threshold beam further comprises:

A first vertical rib 510 is disposed inside the first collapse cavity 110 and divides the first collapse cavity 110 into a first sub-cavity 111 and a second sub-cavity 112, wherein the first sub-cavity 111 is located on a side of the second sub-cavity 112 away from the battery mounting portion 401; and

The second vertical rib 520 is disposed inside the second collapse cavity 210 and divides the second collapse cavity 210 into a third sub-cavity 211 and a fourth sub-cavity 212 . The third sub-cavity 211 is located on a side of the fourth sub-cavity 212 away from the battery mounting portion 401 .

Please refer to FIG. 2 . In this embodiment, the threshold beam further includes a first vertical rib 510 and a second vertical rib 520. The first vertical rib 510 is arranged inside the first collapse cavity 110, and the first collapse cavity 110 is divided into a first sub-cavity 111 and a second sub-cavity 112. The first vertical rib 510 is arranged to improve the structural strength of the first collapse cavity 110, so that the first collapse cavity 110 can absorb more energy when collapsing, further reducing the personal injury caused by the collision; and the first vertical rib 510 improves the rigidity of the first beam body 100, so that the first beam body 100 can transfer more collision force to the battery unit 1000 of the vehicle, further reducing the deformation of the threshold beam. The second vertical rib 520 is arranged inside the second collapse cavity 210, and the second collapse cavity 210 is divided into a third sub-cavity 211 and a fourth sub-cavity 212. The second vertical rib 520 is arranged to improve the structural strength of the second collapse cavity 210, so that the second collapse cavity 210 can absorb more energy when collapsing, further reducing the personal injury caused by the collision.

Optionally, the thickness of the second vertical rib 520 is smaller than the thickness of the first vertical rib 510 .

Please refer to Figure 2. In this embodiment, the thickness of the second vertical rib 520 is less than the thickness of the first vertical rib 510. Since the first beam body 100 needs to transfer the collision force to the battery cell 1000, the first vertical rib 510 is set thicker, which can improve the rigidity of the first beam body 100 and ensure that the first beam body 100 transfers sufficient collision force to the battery cell 1000 to reduce the deformation of the threshold beam. The second vertical rib 520 is set thinner to reduce the weight of the threshold beam.

Optionally, the volume of the first sub-cavity 111 is greater than the volume of the second sub-cavity 112; and/or,

The volume of the third sub-cavity 211 is greater than the volume of the fourth sub-cavity 212; and/or,

The threshold beam further includes a transverse rib 530 , wherein the first sub-cavity 111 is provided with the transverse rib 530 , and/or the second sub-cavity 112 is provided with the transverse rib 530 , and/or the third sub-cavity 211 is provided with the transverse rib 530 ; and/or,

The third sub-cavity 211 has a third side wall 202 close to the battery mounting portion 401 and extending vertically. The third side wall 202 is arranged on a side of the second side wall 201 away from the battery mounting portion 401 to form a first avoidance space 910 between the third side wall 202 and the second side wall 201 .

Please refer to Figure 1. In this embodiment, since the first sub-cavity 111 is close to the outside of the vehicle and the second sub-cavity 112 is close to the battery unit 1000 on the inside of the vehicle, the volume of the first sub-cavity 111 is greater than the volume of the second sub-cavity 112. The first sub-cavity 111 provides a larger crush energy absorption space for side collisions, reducing the harm of collisions. The structural strength of the second sub-cavity 112 is better, which can better ensure the strength of the sill beam itself.

Please refer to Figure 1. In this embodiment, since the third sub-cavity 211 is close to the outside of the vehicle and the fourth sub-cavity 212 is close to the battery unit 1000 on the inside of the vehicle, the volume of the third sub-cavity 211 is greater than that of the fourth sub-cavity 212. The third sub-cavity 211 provides a larger crush energy absorption space for side collisions, reducing the hazards of collisions. The structural strength of the fourth sub-cavity 212 is better, which can better ensure the strength of the sill beam itself.

Please refer to Figure 2. In this embodiment, the threshold beam also includes a transverse rib 530. The transverse rib 530 can be arranged inside the first sub-cavity 111 to strengthen the structural strength of the threshold beam at the first sub-cavity 111 and reduce the deformation of the threshold beam; the transverse rib 530 can also be arranged inside the second sub-cavity 112 to strengthen the structural strength of the threshold beam at the second sub-cavity 112 and reduce the deformation of the threshold beam; the transverse rib 530 can also be arranged inside the third sub-cavity 211 to strengthen the structural strength of the threshold beam at the third sub-cavity 211 and reduce the deformation of the threshold beam.

Please refer to Figure 3. In this embodiment, the third sub-cavity 211 has a third side wall 202 close to the battery mounting portion 401 and extending vertically. Since the third side wall 202 is arranged on the side of the second side wall 201 away from the battery mounting portion 401, the third side wall 202 and the second side wall 201 are staggered to form a first avoidance space 910 between the third side wall 202 and the second side wall 201. The first avoidance space 910 is located on the inner side of the vehicle. Pipelines, lines, etc. of the vehicle can be arranged in the first avoidance space 910. On the one hand, it is convenient for the installation and maintenance of the pipelines and lines. On the other hand, it makes the overall structure of the vehicle more compact.

The threshold beam is connected to the seat cross beam of the vehicle through the fourth beam body 400. The third collapse cavity 310 and the fourth collapse cavity 410 provide a larger collapse energy absorption space for side collision, thereby improving the collapse energy absorption effect of the threshold beam. The battery mounting portion 401 is provided on the fourth beam body 400, so that the structure of the threshold beam is more compact and the weight of the threshold beam is reduced.

Optionally, the threshold beam further includes a first inlay 610, the first inlay 610 is provided with a fifth collapse cavity, and is fixed inside the third collapse cavity 310; and/or,

Please refer to FIG. 2 . In this embodiment, a first inlay 610 can be arranged inside the third collapse cavity 310. By arranging the first inlay 610 inside the third collapse cavity 310, the structural strength of the third beam 300 can be improved, so that the third beam 300 transmits the collision force to the fourth beam 400, and then disperses it to the seat crossbeam of the vehicle through the fourth beam 400, thereby reducing the deformation of the threshold beam and the intrusion of the threshold beam into the cabin space. The first inlay 610 is provided with a fifth collapse cavity, so that the first inlay 610 can also collapse and absorb energy, ensuring the collapse and energy absorption effect of the threshold beam, while reducing the weight of the first inlay 610, thereby reducing the weight of the threshold beam.

Please refer to FIG. 2 . In this embodiment, a second inlay 620 can be arranged inside the fourth collapse cavity 410. By arranging the second inlay 620 inside the fourth collapse cavity 410, the structural strength of the fourth beam 400 can be improved, so that the fourth beam 400 transmits the collision force to the seat crossbeam of the vehicle, thereby reducing the deformation of the threshold beam and the intrusion of the threshold beam into the cabin space. The second inlay 620 is provided with a sixth collapse cavity, so that the second inlay 620 can also collapse and absorb energy, ensuring the collapse and energy absorption effect of the threshold beam, while reducing the weight of the second inlay 620, thereby reducing the weight of the threshold beam.

Please refer to FIG. 3 . In this embodiment, when the user leaves the cabin space and enters the external environment, the user usually extends his legs out of the cabin space first, and the user's calves are likely to collide with the door sill beam. The third collapse chamber 310 has a fourth side wall 301 that is away from the battery installation portion 401 and extends vertically, and the first collapse chamber 110 has a fifth side wall 102 that is away from the battery installation portion 401 and extends vertically. Since the fourth side wall 301 is arranged on the side of the fifth side wall 102 facing the battery installation portion 401, the fourth side wall 301 and the fifth side wall 102 are staggered, and a second avoidance space 920 is formed between the fourth side wall 301 and the fifth side wall 102. By setting the second avoidance space 920, the door sill beam has a depression toward the interior of the vehicle, thereby reducing the possibility of the door sill beam hitting the user's legs and improving the comfort of the vehicle when in use.

Optionally, the threshold beam further includes a stop structure 700, which is disposed on a side of the third beam body 300 away from the first beam body 100, one end of the stop structure 700 is connected to the third beam body 300 and/or the fourth beam body 400, and the other end of the stop structure 700 extends in a direction away from the first beam body 100; and/or,

Specifically, in this embodiment, the stopper structure 700 is provided at the connection between the third beam body 300 and the fourth beam body 400. The stopper structure 700 is directly formed by the threshold beam, which can reduce the sheet metal parts and connectors of the threshold inner panel, reduce the weight of the vehicle, and can also reduce the sealant at the threshold, thereby reducing the material cost.

Please refer to Figure 1. In this embodiment, the first beam body 100 and the third beam body 300 are arranged on the same side of the fourth beam body 400. The fourth beam body 400 connects the first beam body 100 and the third beam body 300, so that the first beam body 100 can also transmit part of the collision force to the fourth beam body 400, and then disperse it to the seat crossbeam of the vehicle through the fourth beam body 400, thereby further reducing the deformation of the threshold beam and reducing the intrusion of the threshold beam into the cabin space.

Optionally, the threshold beam further includes a sealing structure 800 , one end of which is fixed to the battery mounting portion 401 , and the other end of the sealing structure 800 extends in a direction away from the first beam body 100 . The sealing structure 800 is used for sealing connection with the battery unit 1000 .

Please refer to FIG. 1 . In this embodiment, the threshold beam further includes a sealing structure 800. The sealing structure 800 and the battery unit 1000 are sealed and connected, so that the shell of the battery unit 1000 can directly form the cabin floor, thereby reducing the weight of the vehicle and reducing the manufacturing cost of the vehicle. One end of the sealing structure 800 is fixed to the battery mounting portion 401, and the other end of the sealing structure 800 extends in a direction away from the first beam body 100, so that it is more convenient to seal the sealing structure 800 and the battery unit 1000. The sealing can be achieved by adding a gasket or a sealant. Specifically, in this embodiment, the thickness of the end of the sealing structure 800 close to the battery mounting portion 401 is thicker, and the thickness of the sealing structure 800 increases from the end away from the battery mounting portion 401 to the end close to the battery mounting portion 401, so that the sealing structure 800 has better strength. In the process of driving the vehicle, it is not easy to cause the sealing failure between the sealing structure 800 and the battery unit 1000 due to the vibration of the vehicle.
