Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a vehicle body structure and a vehicle. Background Technology

[0003] In related technologies, the air conditioning intake in the vehicle body structure is located on the upper part of the front bulkhead, which is situated to the side of the water channel. Therefore, during vehicle operation (such as under bumpy conditions or uphill conditions), water from the water channel is likely to pass through the air intake and be drawn into the air conditioning system, affecting the normal operation of the air conditioning system or causing damage. Utility Model Content

[0004] The purpose of this disclosure is to provide a vehicle body structure and vehicle that can prevent water from the drain channel from entering the air intake, thereby avoiding affecting or damaging the air conditioning system.

In addition, in the following description, when referring to the figures, unless otherwise explained, the same reference numerals in different figures denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0046] To achieve the above objectives, such as Figures 1 to 8As shown, according to a first aspect of this disclosure, a vehicle body structure is provided for a vehicle. The vehicle body structure includes a front bulkhead 100 and a drainage channel 200. The front bulkhead 100 includes a vertical plate 120 and a lower cover plate 110. The lower cover plate 110 extends from the vertical plate 120 toward the front of the vehicle and connects to the drainage channel 200. The lower cover plate 110 has an air conditioning inlet 111 and an air inlet baffle 130 is provided on the lower cover plate 110, which surrounds the air conditioning inlet 111 in the circumference.

[0047] The vehicle body structure disclosed herein, as described above, includes a front bulkhead 100 and a drainage channel 200. The front bulkhead 100 includes a vertical plate 120 and a lower cover 110 with an air conditioning inlet 111. The lower cover 110 extends forward and connects to the drainage channel 200 on the front side. An air inlet baffle 130 is mounted on the lower cover 110, surrounding the air conditioning inlet 111. By circumferentially arranging the upwardly extending air inlet baffle 130 around the air conditioning inlet 111, water from the drainage channel 200 is prevented from entering the air conditioning inlet 111, thereby preventing any impact on or damage to the air conditioning system.

[0048] It should be noted that the front bulkhead 100 is a partition structure that separates the passenger compartment from the front compartment. It may include an upper cover 150, a windshield crossbeam 140, a lower cover 110, and a front bulkhead 160. The upper cover 150 and the windshield crossbeam 140 form a vertical plate 120, which generally extends in the height direction of the vehicle. The lower cover 110 generally extends in the longitudinal direction of the vehicle, and the vertical plate 120 and the lower cover 110 are set at an angle. The lower cover 110 extends from the vertical plate 120 toward the water channel 200 in the longitudinal direction X and connects with the water channel 200. The air conditioning inlet 111 is generally aligned with the opening direction of the water channel 200. The opening of the water channel 200 faces upwards in the height direction of the vehicle. The air conditioning inlet 111 and the opening of the water channel 200 are generally aligned in the same direction, meaning the air conditioning inlet 111 can be upwards or tilted relative to the height direction Z, for example, tilted forward or backward. The lower cover 110 can be horizontal or arranged at an angle to the horizontal direction.

[0049] The drainage channel 200 is typically a U-shaped cross-section extending along the left-right direction of the vehicle, designed to collect rainwater and guide its flow to both sides. When installed on the vehicle, the drainage channel is located in front of the front bulkhead 100. The opening direction of the drainage channel 200 refers to the normal direction of the virtual plane containing the upper opening of the drainage channel. This direction is typically upward along the vehicle's height or at a certain angle to the vehicle's height.

[0050] It should be noted that, since the lower cover plate 110 connects the front bulkhead 160 and the windshield crossbeam 140, in order to enhance its supporting and reinforcing effect on the front bulkhead 160, in some embodiments, the lower cover plate 110 is inclined relative to the horizontal plane, that is, it gradually rises from front to back. The air conditioning inlet 111 is arranged in the plane of the lower cover plate 110; therefore, the air conditioning inlet 111 and the opening direction of the water channel 200 are arranged at an angle. In some embodiments, the angle α between the extending direction of the air conditioning inlet 111 and the height direction of the vehicle is less than 20 degrees. The extending direction of the air conditioning inlet 111 is the normal direction of the virtual plane formed by the air conditioning inlet 111. Through the above arrangement, water in front of the air inlet baffle 130 tends to flow towards the water channel 200, preventing water from accumulating at the air conditioning inlet 111. For example, the angle α between the extending direction of the air conditioning inlet 111 and the height direction of the vehicle is 8°-20°.

[0051] It should be noted that vehicles are typically equipped with an air conditioning system. Therefore, in order to allow external air to enter the air conditioning system, an air conditioning inlet 111 for allowing external air to enter needs to be arranged on the front bulkhead 160 or the front bulkhead partition 100 and the lower cover 110, thereby enabling the air conditioning system to enter. In the embodiments of this disclosure, the air conditioning inlet 111 is located on the lower cover 110 and communicates with the outside through the ventilation opening 501 of the ventilation cover 500 above the water channel 200, thereby enabling the air conditioning system to enter.

[0052] It should be noted that the front bulkhead 100 may include a vertical panel 120, which includes an upper cover 150 and a windshield crossbeam 140. The upper end of the windshield crossbeam 140 is connected to a lower cover 110. The lower cover 110 is located between the windshield crossbeam 140 and the drainage channel 200. The drainage channel 200 is located in front of the lower cover 110 in the front-rear direction X and is fixedly connected to the overhanging structure 112 of the lower cover 110. The drainage channel 200 can be constructed with any suitable structure to collect water from the windshield and wipers and discharge it through the drain outlet 201. Related technologies can be consulted, and will not be elaborated here.

[0053] Optionally, the drainage channel 200 includes a receiving cavity for collecting rainwater, the receiving cavity including a first region 202; the first region 202 corresponds to the air inlet baffle 130 in the vehicle's longitudinal direction X, that is, in the vehicle's longitudinal direction, the projection area of ​​the air inlet baffle 130 on the drainage channel 200 is defined as the first region 202. In the vehicle's height direction Z, the lowest point 130a of the upper end of the air inlet baffle 130 is higher than the highest point 202a of the first region 202. Specifically, to prevent rainwater in the first region from crossing the air inlet baffle 130 and entering the air conditioning inlet 111, it is necessary to ensure that the lowest point 130a of the upper end of the air inlet baffle 130 is higher than the highest point 202a of the first region 202 of the drainage channel 200. It should be noted that the highest point of the first region 202 refers to the position of the upper edge of the rainwater when the rainwater contained in the first region 202 reaches its maximum volume, which is defined as the highest point 202a of the first region 202.

[0054] like Figure 2 , Figure 7 and Figure 8 As shown, the air inlet baffle 130 extends upward from the air conditioning air inlet 111, and all positions of the upper edge of the air inlet baffle 130 are higher than the highest point 202a of the first region 202 of the water trough 200. This arrangement can prevent water from flowing over the air inlet baffle 130 and into the air conditioning air inlet 111 due to water accumulation in the water trough 200 during heavy rain, thus extending the service life of the air conditioning system. At the same time, it can also prevent water from entering the passenger compartment.

[0055] In some embodiments, the lower cover plate 110 is connected to the front bulkhead 160 to form a cantilever structure 112, that is, the rear of the water trough 200 overlaps with the cantilever structure 112 and is connected by bolts or welds. The front of the water trough 200 overlaps with the wheel arch 700 and the first side beam 400 of the front compartment. The drain outlets 201 of the water trough 200 are arranged on both sides in the left and right direction of the water trough 200, with an overall trend of being higher in the middle and lower on both sides.

[0056] The air inlet baffle 130 can be constructed using any suitable structure. For example, the air inlet baffle 130 can be constructed as a ring structure similar in shape to the air conditioner air inlet 111, with its bottom connected to the top of the air conditioner air inlet 111 and its upper part extending upward to a certain height. The air inlet baffle 130 blocks the water flow towards the air conditioner air inlet 111, preventing rainwater from entering the air conditioning system through the air conditioner air inlet 111.

[0057] like Figure 5As shown, in some embodiments, the air inlet baffle 130 includes a connecting section 131 and an inclined section 132 connected above the connecting section 131. The inclined section 132 is inclined in a direction away from the center of the air conditioning air inlet 111. The connecting section 131 is an annular frame, and the inclined section 132 is a conical frame, with an open (flared) shape from bottom to top. The bottom of the connecting section 131 is circumferentially connected to the air conditioning air inlet 111, and the inclined section 132 is sealed to the upper circumferential part of the connecting section 131. The connecting section 131 can block rain when the amount of rain is small, while the inclined section 132, which is arranged outwards away from the center of the air conditioning air inlet 111, prevents water from the drainage channel 200 from entering the air conditioning air inlet 111 from the top. The inclined section 132 is inclined towards the drainage channel 200, and part of its structure extends forward, which can suppress vertically jumping water droplets from entering the air conditioning air inlet 111. At the same time, it is understandable that the setting of the inclined section 132 further increases the large air intake area and improves the air intake velocity of the air conditioning system.

[0058] It should be noted that the connecting section 131 and the inclined section 132 can be integrally formed, that is, they can be a single part and formed using a suitable processing method. Of course, the connecting section 131 and the inclined section 132 can also be fixedly connected to form the air inlet baffle 130.

[0059] It should be noted that the air inlet baffle 130 does not have to be in the form of a flared mouth. At the same time, the height of the air inlet baffle 130 can be appropriately increased. This can also prevent rainwater from entering the air conditioner air inlet 111, and at the same time, it can simplify the molding process of the air inlet baffle 130 and reduce costs.

[0060] like Figure 6 As shown, in order to achieve drainage of the water trough 200, in some embodiments of this disclosure, the water trough 200 includes a drain outlet 201. Viewed from the front of the vehicle to the rear, the drain outlet 201 can be located to the left of the air conditioning inlet 111. The water trough 200 may have two drain outlets 201, one located near the left side beam 400 of the front compartment, and the other near the right side beam 400 of the front compartment. The left drain outlet 201 is located to the left of the air conditioning inlet 111, and the water trough 200 at this location can also be designed to be recessed or sunken to better guide rainwater from the center of the receiving cavity to the sides.

[0061] To improve the strength and rigidity of the water channel 200 and further guide the water flow, such as Figure 6As shown, in some embodiments, the drainage channel 200 further includes a reinforcing support plate 210 disposed on the drainage channel 200. The reinforcing support plate 210 is located above the drain outlet 201. In the vehicle height direction, the projections of the reinforcing support plate 210 and the air conditioning inlet 111 at least partially overlap. In the longitudinal direction X, the reinforcing support plate 210 is located in front of the air conditioning inlet 111. There are two reinforcing support plates 210, located at the left and right ends of the drainage channel 200 respectively, and both extending from the front compartment first side beam 400 towards the center. Since the left reinforcing support plate 210 is located above the drain outlet 201 of the drainage channel 200 and is connected to the lower cover plate 110, the drainage channel 200 and the front compartment first side beam 400 respectively, and its projection in the vehicle height direction at least partially overlaps with the projection of the air conditioning inlet 111, it can support the structure of the rear lower cover plate 110 and improve its strength.

[0062] It should be noted that reinforcing support plates 210 connected to the water trough 200 can be arranged on both sides of the water trough 200. The reinforcing support plates 210 have reinforcing ribs in the front and rear directions to improve the overall shape of the water trough 200.

[0063] To conceal the lower water channel 200 and the front bulkhead 100, such as Figure 6 As shown, optionally, the vehicle body structure also includes a ventilation cover 500 with a vent 501, the ventilation cover 500 at least partially covering the air conditioning inlet 111 and the water channel 200. This arrangement increases the air intake path, preventing the air intake from the vent 501 from directly blowing water into the air conditioning inlet 111 (first area 202), thereby preventing water from the water channel 200 from being blown into the air conditioning inlet 111.

[0064] The ventilation cover 500 is located above the air conditioning inlet 111 and the water channel 200. At least a portion of the structure of the ventilation cover 500 is located in front of the air conditioning inlet 111 in the vehicle's longitudinal direction X. The ventilation cover 500 can be located directly above the water channel 200 and to the side (above the front side) of the air conditioning inlet 111. A ventilation opening 501 can be provided on it for the inflow of outside air. This arrangement can shield the water channel 200 and the air conditioning inlet 111 through the ventilation cover 500, while also preventing rainwater from falling directly into the air conditioning inlet 111.

[0065] The ventilation opening 501 of the ventilation cover 500 can be constructed using any suitable structure, and its location can also be designed appropriately according to actual needs, such as... Figure 6As shown, in some embodiments, the vent 501 is located in the middle of the vent cover 500 in the left-right direction Y, and in the vehicle height direction, the vent 501 does not overlap with the air conditioning inlet 111. In the left-right direction Y, the air conditioning inlet 111 is closer to the left front compartment first side beam 400 than the vent 501. The vent 501 is located in the middle of the vent cover 500, while the air conditioning inlet 111 is located near the outside of the front compartment first side beam. Outside air enters from the middle and needs to travel a certain path before reaching the air conditioning inlet 111 near the edge. This prevents rainwater from directly entering the air conditioning inlet 111. Furthermore, considering that the drain outlet 201 is also located at the edge of the drainage channel 200 in the left-right direction Y, the intake air can easily guide the rainwater inside the drainage channel 200 to the left drain outlet 201, improving drainage efficiency. Figure 6 As shown in the figure, the dashed lines with arrows represent the air intake path; the solid lines with arrows represent the air drainage path.

[0066] The shape of the air conditioner inlet 111 is not specifically limited and can be designed as needed. For example, it can be circular, elliptical, or other polygonal, as long as it can ensure the air intake of the air conditioning system. In some embodiments, the air conditioner inlet 111 can be triangular or quadrilateral. Here, "triangle" refers to a triangle or an approximate triangle, and an approximate triangle can be a triangle with rounded or chamfered corners. "Quadrilateral" also refers to a quadrilateral or an approximate quadrilateral, including squares, rectangles, rhombuses, or trapezoids, etc.

[0067] The lower cover plate 110 can adopt any suitable shape. In some embodiments, in order to improve the connection reliability between the lower cover plate 110 and the side panel (e.g., the first side beam 400 of the front compartment), the width of the lower cover plate 110 gradually increases from the center in the left-right direction Y of the vehicle toward the first side beam 400 of the front compartment, thereby increasing the connection strength by increasing the connection length with the first side beam 400 of the front compartment.

[0068] The air conditioning inlet 111 can be located on the lower cover 110 near the first side beam 400 of the front compartment. Therefore, based on the shape of the lower cover 110 at this location, the air conditioning inlet 111 can be designed as a triangle. This triangular air conditioning inlet 111 includes an outer edge 1111, a front edge 1112, and a rear edge 1113 connected in sequence. The lower cover 110 includes an outer edge for connecting with the side panel (not marked in the figure) or the first side beam 400 of the front compartment, a front edge for overlapping with the water trough 200, and a rear edge for connecting with the rear windshield beam 140. The extension direction of the outer edge is generally parallel to the front-rear direction; the extension direction of the front edge is generally parallel to the left-right direction; and the extension direction of the rear edge is inclined relative to the left-right direction Y, and the distance between the rear edge and the front edge gradually increases from the inside to the outside. The three sides of the triangle are roughly parallel to the outer side, front side, and rear side. Specifically, the outer side 1111 is roughly parallel to the outer side, the front side 1112 is roughly parallel to the front side, and the rear side 1113 is roughly parallel to the rear side, thus conforming to the shape of the rear side. Since the three sides of the triangular air conditioning inlet 111 are roughly parallel to the side of the lower cover plate 110, the shape of the air conditioning inlet 111 is similar to that of the lower cover plate 110 at this location. By placing the air conditioning inlet 111 inside the lower cover plate 110, the size of the air conditioning inlet 111 can be maximized while ensuring the strength and rigidity of the lower cover plate 110, thus guaranteeing the air intake requirements.

[0069] Optionally, in the direction from the air conditioning inlet 111 to the first side beam 400 of the front compartment, the distance between the front edge 1112 and the rear edge 1113 of the air conditioning inlet 111 gradually increases. That is, the distance between the front edge 1112 and the rear edge 1113 in the front-rear direction increases. The air conditioning inlet 111 is triangular in shape, with a larger outer side and a smaller inner side.

[0070] like Figure 4 As shown, in some embodiments, the air conditioning inlet 111 is triangular, with one corner of the triangle facing the vent 501. By arranging one corner of the triangle towards the vent 501, when air flows from the vent 501 of the ventilation cover 500 towards the air inlet, wind resistance can be reduced, thereby increasing the air intake velocity.

[0071] Since the windshield of a vehicle is generally curved, with the middle relatively forward and the sides relatively backward, the air conditioning intake 111 can effectively utilize the front-to-back space by placing it on the sides of the vehicle body. If it is placed in the middle of the vehicle (in the middle of the left-to-right direction), the air conditioning intake 111 will occupy too much front-to-back space, which will push the water channel 200 forward, compress the front compartment space, and make the front compartment layout even more cramped.

[0072] The air inlet baffle 130 can be connected to the lower cover plate 110 in any suitable manner. In some embodiments, the air inlet baffle 130 is fixedly connected to the lower cover plate 110, and the gap between them is sealed with sealant; and / or, the air inlet baffle 130 can be integrally formed with the lower cover plate 110.

[0073] In some embodiments, the air inlet baffle 130 and the lower cover plate 110 can be connected and sealed by spot welding and applying adhesive, which can not only achieve a fixed connection between the two, but also ensure the seal between them, preventing rainwater from flowing into the air conditioner air inlet 111 through the gap between them.

[0074] In the structural design of the air inlet baffle 130 and the lower cover plate 110, the forming method of the air inlet baffle 130 affects its structural performance. For example, the air inlet baffle 130 and the lower cover plate 110 can be integrally formed using a deep-drawing process. Deep-drawing is a part processing method that uses a mold under the action of a press to plastically deform sheet metal, thereby obtaining parts of the required shape and size. Using this deep-drawing process to integrally form the air inlet baffle 130 and the lower cover plate 110 has many advantages: Firstly, the integrally formed structure reduces the connection points between parts, greatly improving the overall structural strength and stability, and reducing the risk of failure due to loose connections. Secondly, integral forming simplifies the assembly process, improves production efficiency, and reduces production costs. Furthermore, integral forming can also solve the sealing problem between the two, further improving the waterproof effect and preventing water ingress into the air conditioning air inlet 111 due to gaps between them.

[0075] To prevent rainwater in the drainage channel 200 from overflowing the air inlet baffle 130 and entering the air conditioning inlet 111 during normal vehicle operation (especially uphill), in some embodiments, the height of the air inlet baffle 130 in the vertical direction Z is greater than or equal to 10mm. Here, the height of the air inlet baffle 130 refers to the vertical distance between the lower and upper ends of the air inlet baffle 130 in the vehicle's vertical direction Z. Theoretical and experimental studies have shown that when the height of the air inlet baffle 130 is equal to or greater than 10mm, rainwater overflowing the air inlet baffle 130 and entering the air conditioning inlet 111 can be prevented to the greatest extent possible.

[0076] In some preferred embodiments, the height of the air inlet baffle 130 in the vehicle height direction is 10-30mm. This height design satisfies almost all water-blocking requirements of the drainage channel 200. By designing the height as described above, combined with the outward-flaring design of the upper edge of the air inlet baffle 130, the overall shape resembles a trumpet. The length of the outward-flaring structure can be appropriately designed, wherein the length of the outward-flaring structure (inclined section 132) is less than the length of the connecting part. If the outward-flaring structure is too short, it cannot block rainwater from flowing in; if the outward-flaring structure is too long, it leads to reduced local rigidity and material waste. The trumpet-shaped structure further reduces the risk of water entering the air conditioning inlet 111. The entire circumference of the air conditioning inlet 111 is provided with an outward-flaring structure. The rear outward-flaring structure prevents rainwater flowing down from the front window from entering the air conditioning inlet 111, while the front and side outward-flaring structures prevent rainwater from flowing back from the drainage channel 200 to the air conditioning inlet 111 during uphill or bumpy conditions.

[0077] Optionally, the vehicle body structure also includes an air inlet cover 300 located at the lower end of the air conditioning inlet 111. The air inlet cover 300 is connected to the lower cover plate 110 and the air conditioning system (air conditioning housing 600). The air inlet cover 300 has an air intake channel 310 connecting the air conditioning inlet 111 and the air intake end of the air conditioning housing 600, for guiding the air from the air conditioning inlet 111 into the air conditioning system.

[0078] The air inlet cover 300 can be constructed in any shape. To avoid obstructing the front cabin wiring harness through-hole 161 of the front bulkhead 160 connected below the lower cover plate 110, which is located near the side of the front bulkhead 160 in the left-right direction, the following applies. Figure 3 As shown, in some embodiments, the distance between the air inlet cover 300 and the first side beam 400 of the front compartment gradually increases in the left-right direction of the vehicle, thereby forming a certain avoidance area between the air inlet cover 300 and the side panel to leave space for the wiring harness in the front compartment.

[0079] like Figure 1 and Figure 2 As shown, the front bulkhead 100 also includes a front bulkhead 160 connected to the lower cover 110; the front bulkhead 160 is provided with a front compartment wiring harness through-hole 161, and the front compartment wiring harness through-hole 161 is located below the air conditioning inlet 111. The front compartment wiring harness through-hole 161 connects the front compartment and the passenger compartment of the vehicle. In the longitudinal direction, the front compartment wiring harness through-hole 161 corresponds to the aforementioned clearance area, thereby facilitating the passage and arrangement of the front compartment wiring harness.

[0080] In some embodiments, the vehicle body structure further includes a wheel arch 700, with the air conditioning intake 111 located on the side of the wheel arch 700 away from the first side beam 400 of the front compartment in the left-right direction of the vehicle. The projection of the wheel arch 700 in the horizontal plane lies between the air conditioning intake 111 and the first side beam 400 of the front compartment in the left-right direction of the vehicle. The front bulkhead 160 behind the wheel arch 700 has no openings, thus the force transmitted rearward by the wheel arch 700 can be effectively absorbed by the front bulkhead 160, ensuring the reliability of the force transmission path. In some embodiments, the projection of the front compartment wiring harness through-hole 161 in the horizontal plane at least partially overlaps with the projection of the air conditioning intake 111 in the horizontal plane. The front compartment wiring harness through-hole 161 can be located directly below the air conditioning intake 111, facilitating the arrangement of the front compartment wiring harness. Considering that there are related devices at the location of the air conditioning intake 111, this arrangement of the front compartment wiring harness through-hole 161 can also save on wiring harness costs.

[0081] The wheel cover 700 is located in front of the air conditioning inlet 111. Therefore, the projection of the front cabin wiring harness through hole 161 on the horizontal plane overlaps with the projection of the air conditioning inlet 111 on the horizontal plane at least partially. Thus, the position of the front cabin wiring harness through hole 161 is located behind the wheel cover 700, which can effectively protect the wiring harness. In addition, the wheel cover 700 can also protect the weak part of the opening on the front bulkhead 160.

[0082] It should be noted that the front cabin wiring harness through-hole 161 can also be located on the lower side of the air conditioning inlet 111.

[0083] Optionally, in the left-right direction Y of the vehicle, the distance L2 between the outer edge of the front compartment wiring harness through-hole 161 and the first side beam 400 of the front compartment is less than the distance L1 between the outer edge 1111 of the air conditioning inlet 111 and the first side beam 400 of the left side of the front compartment. This distance can be understood as the projected distance on the horizontal plane between the edge of the front compartment wiring harness through-hole 161 near its edge and the first side beam 400 of the front compartment, and the projected distance on the horizontal plane between the outer edge 1111 of the air conditioning inlet 111 and the first side beam 400 of the front compartment. With the above arrangement, the installation of the front compartment wiring harness through-hole 161 can be ensured while increasing the area of ​​the air conditioning inlet 111.

[0084] In some embodiments, the distance between the front cabin wiring harness through-hole 161 and the front cabin first side beam 400 is 60-100mm; the distance between the air conditioning inlet 111 and the front cabin first side beam 400 is 80-120mm. For example, the distance between the front cabin wiring harness through-hole 161 and the front cabin first side beam 400 can be 80mm, and the distance between the air conditioning inlet 111 and the front cabin first side beam 400 can be 100mm.

[0085] like Figure 3As shown, the front cabin wiring harness through-hole 161 is located near the side of the first side beam 400 of the front cabin and is positioned directly below the air conditioning inlet 111. The air conditioning inlet 111 and the front cabin wiring harness through-hole 161 are positioned close to the first side beam 400, while avoiding the central location, because the air conditioning unit 600 needs to be located in the center of the passenger compartment, and the front cabin wiring harness and air conditioning inlet 111 cannot pass through the cabin in the center. Being too close to the first side beam 400 would make the installation of the front cabin wiring harness difficult due to wheel arch interference, while being too far from the first side beam 400 would cause the front cabin wiring harness to occupy the space of other modules. Therefore, the air conditioning inlet 111 is positioned directly above the front cabin wiring harness through-hole 161, and the distance between the air conditioning inlet 111 and the first side beam 400 is greater than the distance between the wiring harness through-hole and the first side beam 400. At the same time, if the distance between the air conditioning inlet 111 and the first side beam 400 of the front compartment is too large, it will increase the distance between the air conditioning unit 600 and the air inlet cover 300; if the distance is too small, there will be insufficient space for arrangement.

[0086] The evaporator pipe through-hole 162 connects the front compartment and passenger compartment of the vehicle, allowing the evaporator pipes to pass through. These evaporator pipes include a high-pressure air conditioning line 610 and a low-pressure air conditioning line 620. The evaporator pipe through-hole 162 can be located at any suitable position on the front bulkhead 160, such as... Figure 1 As shown, in some embodiments, the front bulkhead 160 is also provided with an evaporator pipe through hole 162, which is located in the middle of the front bulkhead 160 in the left-right direction Y.

[0087] like Figure 1 As shown, the high-pressure air conditioning line 610 and the low-pressure air conditioning line 620 of the air conditioning system are arranged in the middle of the front bulkhead 160, located in the middle 50% area of ​​the lower part of the entire front bulkhead. This position corresponds to the front of the air conditioning unit 600. This arrangement (i.e., the evaporator pipe through hole 162 is roughly located in the middle of the front bulkhead 160) ensures that the high-pressure air conditioning line 610 and the low-pressure air conditioning line 620 can directly connect to the air conditioning unit 600 after passing through the front bulkhead 160. After the high-pressure air conditioning line 610 and the low-pressure air conditioning line 620 pass through the evaporator pipe through hole 162 through the front bulkhead 160, there is no need to arrange additional pipelines in the compartment, thus freeing up interior space.

[0088] It should be noted that the vehicle body structure may also include side panels and front compartment side beams. The front compartment side beams include a first front compartment side beam 400 and a second front compartment side beam (not shown in the figure). The first front compartment side beam 400 is arranged near the air conditioning inlet 111, and the second front compartment side beam is arranged away from the air conditioning inlet 111. One side panel and the first front compartment side beam 400 are arranged on the left side of the front bulkhead 160 and the lower cover 110, and the other side panel and the second front compartment side beam are arranged on the right side of the front bulkhead 160 and the lower cover 110. The front bulkhead 100, side panels, the first front compartment side beam 400, the first front compartment side beam, and other components form the front compartment in front of the front bulkhead 160 and the lower cover 110; the side panels, the first front compartment side beam 400, the first front compartment side beam, and another component form the passenger compartment behind the front bulkhead 160 and the lower cover 110.

[0089] In other embodiments, the front bulkhead 160 also includes an evaporator pipe through-hole 162, which is located below the air conditioning inlet 111. The projection of the air conditioning inlet 111 in the vehicle height direction at least partially overlaps with the projection of the evaporator pipe through-hole 162 in the vehicle height direction. In other words, both the front compartment wiring harness through-hole 161 and the evaporator pipe through-hole 162 are located below or to the side of the air conditioning inlet 111, utilizing the space between the air inlet cover 300 and the first side beam 400 of the front compartment, thus improving the compactness of the entire wiring structure.

[0090] In some embodiments, the front compartment wiring harness through-hole 161 and the evaporator pipe through-hole 162 are spaced apart in the vehicle height direction, that is, they can be arranged one above the other to further utilize the space in the height direction.

[0091] According to a second aspect of this disclosure, a vehicle is also provided, including the aforementioned body structure, and thus the vehicle also possesses all the advantages of the aforementioned body structure.

[0092] The disclosed vehicle body structure includes a front bulkhead 100 and a water channel 200. The front bulkhead 100 includes a vertical plate 120 and a lower cover 110 with an air conditioning inlet 111. The lower cover 110 extends from the vertical plate 120 to the front of the vehicle and is connected to the water channel 200. The opening directions of the air conditioning inlet 111 and the water channel 200 are generally the same. By circumferentially arranging an upwardly extending inlet baffle 130 around the air conditioning inlet 111, water inside the water channel 200 is prevented from entering the air conditioning inlet 111, thereby avoiding affecting the operation of the air conditioning system or damaging the air conditioning system.

[0093] Furthermore, the air inlet baffle 130 is designed to extend upward from the air conditioning air inlet 111, with a height of ≥20mm, and the top is designed with an outward-extending flared structure to prevent excessive rainwater from accumulating here and causing too much external water to enter the air conditioning system.

[0094] Furthermore, the air inlet baffle 130 and the lower cover plate 110 are integrally formed by deep drawing process, which simplifies the assembly process, improves production efficiency, and enhances the waterproof effect.

[0095] Furthermore, the air conditioning inlet 111 is located on the lower cover plate 110, the front cabin wiring harness through hole 161 and the evaporator pipe through hole 162 are arranged on the front bulkhead 160, and the front cabin wiring harness through hole 161 is located on the side of the first side beam 400 of the front cabin (at a distance of about 80mm), and the air conditioning inlet 111 is located directly above the front cabin wiring harness through hole 161 and has a slightly larger gap with the first side beam 400 of the front cabin (at a distance of about 100mm). The inclined arrangement of the air inlet cover 300 provides space for the front cabin wiring harness.
