[0030] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary, and embodiments of the present application are described in detail below.

[0031] The following drawings are referred to Figures 1-6 A cabin 100 according to an embodiment of the present application is described. The cabin 100 of the present embodiment can be applied to a vehicle.

[0032] In combination Figures 1-4As shown, the cockpit 100 according to the embodiment of the utility model can mainly include: a cockpit body 10 and a roof assembly 20, wherein the cockpit body 10 includes two rocker beams 11, both of which extend front and back to limit the size of the cockpit 100 in the front and back direction, and both of which are arranged at intervals in the left and right direction, so that the balance of the cockpit 100 in the left and right direction can be ensured.

[0033] Further, the rocker beam 11 is integrally formed with an A-pillar portion 116, in addition to which the rocker beam 11 is integrally formed with a wheel cover outer plate portion 114, a torsion box portion 115, the A-pillar portion 116, a rocker beam portion 117 and a B-pillar portion 118, wherein the A-pillar portion 116 is located at the front end of the rocker beam 11, the front and back ends of the rocker beam portion 117 are connected to the lower end of the A-pillar portion 116 and the lower end of the B-pillar portion 118 respectively, and the wheel cover outer plate portion 114 and the torsion box portion 115 are both arranged on the front side of the A-pillar portion 116, so as to constitute the basic structure of the wheel cover assembly.

[0034] In this way, on the one hand, only one mold needs to be developed and used in the process of vehicle development and production, so that the wheel cover outer plate portion 114, the torsion box portion 115, the A-pillar portion 116, the rocker beam portion 117 and the B-pillar portion 118 can all be integrally formed. This can reduce the mold development of the rocker beam 11, simplify the structure of the rocker beam 11, and further make the structure of the cockpit 100 more compact, which is conducive to improving the integration of the vehicle body.

[0035] On the other hand, after the wheel cover outer plate portion 114, the torsion box portion 115, the A-pillar portion 116, the rocker beam portion 117 and the B-pillar portion 118 are integrally formed on the rocker beam 11, the connection between the wheel cover outer plate portion 114, the torsion box portion 115, the A-pillar portion 116, the rocker beam portion 117 and the B-pillar portion 118 can be reduced. In this way, during vehicle driving, the risk of connection failure can be avoided, so as to improve the reliability of the vehicle body and further improve the safety performance of the vehicle.

[0036] Further, the roof assembly 20 is located above the cockpit body 10 and is connected to the cockpit body 10, and is adapted to limit the size of the cockpit 100 in the up and down direction, so that the roof assembly 20 and the cockpit body 10 can jointly constitute the space of the cockpit 100, for constituting part of the cockpit 100 in the vehicle body framework.

[0037] Further, the roof assembly 20 comprises a roof component 21 and first reinforcing beams 22, the first reinforcing beams 22 extend along the front-rear direction and are gradually inclined upward in the front-rear direction, the rear end of the first reinforcing beams 22 can be connected with the front end of the roof component 21 to jointly form the roof assembly 20, so that the roof assembly 20 can bear the pressure and impact on the roof of the vehicle. The rear end of the roof component 21 is connected with the cabin body 10, so that the pressure and impact on the roof of the cabin 100 can be transmitted and dispersed to the cabin body 10, thereby improving the structural reliability of the vehicle frame.

[0038] Further, the first reinforcing beams 22 are two and are spaced apart in the left-right direction, the upper ends of the two first reinforcing beams 22 are connected with the left and right ends of the front side of the roof component 21, so that the two first reinforcing beams 22 can bear the pressure and impact on the left and right sides of the vehicle, and the pressure and impact on the roof of the cabin 100 can be dispersed left and right, thereby ensuring the impact resistance of the vehicle.

[0039] Further, the upper end of the A-pillar portion 116 of the two rocker beams 11 is provided with a first lap portion 111, the lower end of the two first reinforcing beams 22 is provided with a second lap portion 221, the two first lap portions 111 and the two second lap portions 221 are lap matched one by one, so that the upper end of the A-pillar portion 116 of the two rocker beams 11 and the lower end of the two first reinforcing beams 22 are connected in the up-down direction to form the A-pillar in the cabin 100, so that the upper end of the A-pillar portion 116 of the rocker beam 11 and the first reinforcing beam 22 can jointly bear the pressure and impact on the roof and the side of the vehicle, thereby ensuring the driving safety of the vehicle.

[0040] Further, the first lap portion 111 of the two rocker beams 11 is protrudingly arranged towards the side where the two rocker beams 11 are closer to each other in the left-right direction, so that the size of the first lap portion 111 can be increased while ensuring the flatness of the side where the two rocker beams 11 are away from each other in the left-right direction, the second lap portion 221 of the two first reinforcing beams 22 is protrudingly arranged towards the side where the two first reinforcing beams 22 are closer to each other in the left-right direction, so that the size of the second lap portion 221 can be increased while ensuring the flatness of the side where the two first reinforcing beams 22 are away from each other in the left-right direction.

[0041] In this way, the size of the first lap portion 111 and the second lap portion 221 can be increased, which is conducive to improving the matching strength of the first lap portion 111 and the second lap portion 221, thereby ensuring the structural reliability of the A-pillar in the cabin 100 and improving the overall structural reliability of the cabin 100.

[0042] In combination with Figure 1 and Figure 4As shown, the first lap joint part 111 is a lap surface, and the second lap joint part 221 is a lap block, and the lower surface of the lap block is in close contact with the lap surface. Specifically, the lap joint of the first lap joint part 111 and the second lap joint part 221 is actually the lap joint of the lap surface and the lap block, and the structure of the lap surface and the lap block is simple, the lap joint is reliable, the connection operation of the first reinforcing beam 22 and the A-pillar part 116 can be simplified, and the cooperation reliability of the first reinforcing beam 22 and the A-pillar part 116 can be ensured. In this way, not only can the processing of the first reinforcing beam 22 and the A-pillar part 116 be facilitated, but also the structural reliability of the cabin 100 can be ensured.

[0043] In combination Figure 1 And Figure 4 As shown, the lower surface of the lap block and the lap surface are in lap joint, so that the first reinforcing beam 22 and the A-pillar part 116 can be in upper and lower cooperation to form the structure of the A-pillar in the cabin 100. The lower surface of the lap block and the lap surface can support each other in the up-down direction, and the lower surface of the lap block and the lap surface are both increased in the utility model, which can improve the connection reliability of the first reinforcing beam 22 and the A-pillar part 116, improve the transmission efficiency of the force between the first reinforcing beam 22 and the rocker beam 11, and be beneficial to improving the compression resistance of the A-pillar.

[0044] Further, the lower surface of the lap block and the lap surface are adhesively fixed, which is simple in mode and reliable in connection. In this way, not only can the assembly process of the first reinforcing beam 22 and the A-pillar part 116 be simplified, which is beneficial to simplifying the vehicle production and improving the production efficiency, but also the connection reliability of the upper end of the first reinforcing beam 22 and the A-pillar part 116 can be ensured, and further the structural reliability of the A-pillar can be ensured, which can ensure the ability of the vehicle body frame to resist top pressure and side impact.

[0045] In combination Figure 4 As shown, the lap surface is provided with a first perforation 1111, and the lap block is provided with a second perforation 2211, the first perforation 1111 and the second perforation 2211 correspond to each other and are connected and fixed by the fastener 30. In this way, the connection reliability of the lower surface of the lap block and the lap surface can be improved, and the structural reliability of the A-pillar can be improved.

[0046] Further, the first perforation 1111 and the second perforation 2211 are simple in structure, which can facilitate the processing of the first perforation 1111 on the lap surface and the processing of the second perforation 2211 on the lap block. When the first lap joint part 111 and the second lap joint part 221 are in lap joint, the first perforation 1111 on the lap surface and the second perforation 2211 on the lap block correspond to each other in up-down direction. In this way, the fastener 30 can pass through the first perforation 1111 and the second perforation 2211 at the same time, which can ensure the operation convenience of the fastener 30 connecting the first lap joint part 111 and the second lap joint part 221, and further improve the assembly convenience of the cabin 100.

[0047] According to some other embodiments of the present application, the lower surface of the overlapping block and the overlapping surface are fixedly bonded, and the lower surface of the overlapping block and the overlapping surface are also fastened by the fastener 30, which can further enhance the connection strength of the first overlapping part 111 and the second overlapping part 221, thereby effectively improving the structural reliability of the A-pillar in the cabin 100.

[0048] In combination Figure 4 and Figure 6 As shown in FIGS. 11 and 12, the threshold beam 11 is provided with an abutting portion 112, which is upwardly protruding relative to the overlapping surface to define a limiting step surface 113 with the overlapping surface, and the overlapping block is limited by the limiting step surface 113. Specifically, when the overlapping block is matched with the overlapping surface up and down, the abutting portion 112 on the threshold beam 11 can limit the matching of the overlapping block, and the abutting portion 112 and the overlapping surface have a height difference in the up-down direction to define the limiting step surface 113, and the limiting step surface 113 is extended up and down. In this way, the setting stability of the overlapping block on the overlapping surface can be improved.

[0049] When the A-pillar is subjected to impact and extrusion, the limiting step surface 113 can block the dislocation of the overlapping block and the overlapping surface, thereby improving the reliability of the overlapping block and the overlapping surface, which can prevent the first reinforcing beam 22 from being dislocated with the upper end of the A-pillar portion 116, thereby preventing the A-pillar from being disconnected. In this way, the extrusion and impact resistance of the A-pillar can be improved, thereby facilitating the improvement of the driving safety of the vehicle.

[0050] In combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in FIGS. 11 and 12, the threshold beam 11 is provided with an abutting portion 112, which is upwardly protruding relative to the overlapping surface to define a limiting step surface 113 with the overlapping surface, and the overlapping block is limited by the limiting step surface 113. Specifically, when the overlapping block is matched with the overlapping surface up and down, the abutting portion 112 on the threshold beam 11 can limit the matching of the overlapping block, and the abutting portion 112 and the overlapping surface have a height difference in the up-down direction to define the limiting step surface 113, and the limiting step surface 113 is extended up and down. In this way, the setting stability of the overlapping block on the overlapping surface can be improved.

[0051] Specifically, while the limiting step surface 113 is extended up and down, the limiting step surface 113 and the reference surface parallel to the left-right direction form an angle, which makes the limiting step surface 113 extend obliquely to the rear, which not only allows the limiting step surface 113 to limit the overlapping block in the front-rear direction, but also allows the limiting step surface 113 to limit the overlapping block in the left-right direction.

[0052] When the vehicle is subjected to a top pressure, the top pressure is transmitted from the upper end to the lower end of the first reinforcing beam 22, and then transmitted to the rocker beam 11 through the cooperation of the lapping block and the lapping surface. In this process, since the first reinforcing beam 22 extends forward and backward, the lapping block has a tendency to move forward and backward relative to the lapping surface. The abutting portion 112 and the limiting step surface 113 defined between the abutting portion 112 and the lapping surface extend left and right, and can block the lapping block from moving forward and backward relative to the lapping surface.

[0053] When the vehicle is subjected to a side collision, a lateral force will hit one of the A-pillars on the left and right sides toward the other side. In this process, the lapping block has a tendency to move left and right relative to the lapping surface. The limiting step surface 113 defined between the abutting portion 112 and the lapping surface is inclined rearward, and the limiting step surface 113 can extend forward and rearward. In this way, the lapping block can be blocked from moving left and right relative to the lapping surface.

[0054] In this way, the abutting portion 112 can support the lapping block in the forward and backward directions and the left and right directions at the same time, and can effectively limit the movement of the lapping block in the forward and backward directions and the left and right directions. This can improve the stability of the cooperation between the lapping block and the lapping surface, and can strengthen the ability of the lapping portion at the upper end of the first reinforcing beam 22 and the A-pillar portion 116 to resist forces in the forward and backward directions and the left and right directions. Therefore, the structural reliability of the A-pillar can be effectively improved, and the top pressure resistance and collision resistance of the A-pillar can be improved.

[0055] In the embodiment of the present application, the plane extending in the upward and downward directions and parallel to the left and right directions is set as a reference plane, and the included angle between the limiting step surface 113 and the reference plane is between 0 and 90°.

[0056] Specifically, the included angle between the limiting step surface 113 and the reference plane cannot be too small, otherwise the limiting step surface 113 will be inclined to the front side, and the lapping block cannot be limited left and right by the limiting step surface 113. The included angle between the limiting step surface 113 and the reference plane cannot be too large, otherwise the lapping block cannot be limited forward and backward by the limiting step surface 113. In this way, the included angle between the limiting step surface 113 and the reference plane is between 0 and 90°, which can ensure the reliability of the limiting step surface 113 in limiting the lapping block in the forward and backward directions and the left and right directions.

[0057] In combination Figures 1-6As shown, the limiting step surface 113 includes a first step surface 1131 and a second step surface 1132, and the second step surface 1132 on the two rocker beams 11 is connected to the first step surface 1131 on the two rocker beams 11 at the end adjacent to each other, so that the limiting step on the left rocker beam 11 can be limited and matched with the right side surface of the left lap block, and the left A-pillar can be prevented from being bent towards the inside of the cabin 100 after being impacted. Similarly, the limiting step on the right rocker beam 11 can be limited and matched with the left side surface of the right lap block, and the right A-pillar can be prevented from being bent towards the inside of the cabin 100 after being impacted. In this way, the safety of the cabin 100 can be improved.

[0058] Further, the angle between the first step surface 1131 and the reference surface is β, and the angle between the second step surface 1132 and the reference surface is γ, and β and γ satisfy the relationship: β≤γ. Specifically, the first step surface 1131 and the second step surface 1132 on the limiting step surface 113 have different angles relative to the reference surface, which is beneficial to simultaneously ensure the limiting reliability of the abutting portion 112 to the lap block in the front-rear direction and the left-right direction.

[0059] More specifically, the angle of the first step surface 1131 relative to the reference surface is smaller than the angle of the second step surface 1132 relative to the reference surface, which can make the limiting of the first step surface 1131 to the lap block in the front-rear direction more reliable, and the angle of the second step surface 1132 relative to the reference surface is larger than the angle of the first step surface 1131 relative to the reference surface, which can make the limiting of the second step surface 1132 to the lap block in the left-right direction more reliable.

[0060] In addition, the second step surface 1132 can be inclined rearward relative to the first step surface 1131, so that the first step surface 1131 and the second step surface 1132 form an arch structure, and the limiting step surface 113 is in an arch shape, which is beneficial to improving the structural strength of the limiting step surface 113 and the limiting reliability of the abutting portion 112 to the lap block.

[0061] In combination Figure 3 As shown, the roof assembly 20 further includes a second reinforcing beam 23, which extends in the left-right direction and is connected between the upper ends of the two first reinforcing beams 22, and the second reinforcing beam 23 is connected to the front end of the roof assembly 21, so that the second reinforcing beam 23 can be conveniently connected to the front end of the roof assembly 21, and the setting reliability of the two first reinforcing beams 22 between the roof assembly 21 and the cabin body 10 can be ensured, thereby improving the structural reliability of the left and right A-pillars in the cabin 100.

[0062] In combination Figure 3As shown, the second reinforcing beam 23 and the two first reinforcing beams 22 are integrally formed structural members, so that the second reinforcing beam 23 and the two first reinforcing beams 22 can be integrally manufactured through one process, the development of the whole vehicle mold can be reduced, the connection between the second reinforcing beam 23 and the two first reinforcing beams 22 can be reduced, the connection failure between the second reinforcing beam 23 and the two first reinforcing beams 22 can be avoided, and thus the structural reliability and the integration of the roof assembly 20 can be improved.

[0063] According to the embodiment of the utility model, the cabin 100 can be applied to a vehicle, and the vehicle configured with the embodiment of the utility model can select to set two first lap joints 111 which are arranged close to each other in the left-right direction and protrude on the upper end of the A-pillar part 116 in the two rocker beams 11 after carbon fiberizing the cabin 100, set two second lap joints 221 which are arranged close to each other in the left-right direction and protrude on the lower end of the two first reinforcing beams 22, the first lap joint 111 and the second lap joint 221 are lapped and matched, and are connected by the fastener 30, so that the connection reliability of the first reinforcing beam 22 and the upper end of the A-pillar part 116 can be increased. The abutting block is further arranged on the upper end of the A-pillar part 116 to limit the front-back direction and the left-right direction of the second lap joint 221, so as to enhance the lapping stability of the first lap joint 111 and the second lap joint 221, and thus the anti-pressing and anti-collision ability of the A-pillar in the cabin 100 can be improved, so as to improve the safety performance of the vehicle.
