Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an air intake and ventilation structure and a vehicle. Background Technology

[0002] The front end of a vehicle typically integrates a cooling system, including a matching cooling module and a spoiler, connected to the vehicle body via a front-end frame (including left and right pillars and upper and lower curved beams). In pure electric vehicles, the cooling module is smaller and mounted on the lower curved beam, while the front-end frame size usually remains unchanged to save costs. In this case, using the original-sized spoiler would result in material waste; using a smaller spoiler (meaning a spoiler whose height and width are smaller than the frame's height and width) would require a longer cantilever to connect to the upper curved beam. An excessively long cantilever increases the risk of breakage during vehicle operation, compromising the stability of the spoiler-frame connection. Utility Model Content

[0003] The main purpose of this utility model is to propose an air intake and air guide structure and vehicle, which aims to improve the stability of the connection between the small-sized air guide plate and the frame.

[0004] To achieve the above objectives, this utility model proposes an air intake and air guiding structure, comprising: The front frame includes an upper curved beam, a lower curved beam, and two parallel columns. The two ends of the columns are connected to the upper curved beam and the lower curved beam, respectively. The direction along one column to the other column is defined as the first direction. Two bottom longitudinal beams, and the two columns are respectively connected to the two bottom longitudinal beams; The anti-collision beam has its two ends connected to the two bottom longitudinal beams respectively; A flow guiding assembly includes an upper flow guiding plate and two side flow guiding plates. The upper flow guiding plate includes an upper plate and mounting portions installed on both sides of the upper plate along the first direction. The side flow guiding plates include connected side plates and mounting plates. A through hole is formed at the top of the side plate. The mounting portions pass through the through hole and are connected to the column. The mounting plates are connected to the anti-collision beam.

[0005] In one embodiment, the side plate has a locking hole, and the upper guide plate further includes a buckle installed on both sides of the upper plate along the first direction, the buckle engaging with the locking hole.

[0006] In one embodiment, the side plate is further provided with a limiting hole, and the upper guide plate further includes a limiting tongue installed on both sides of the upper plate along the first direction, the limiting tongue and the limiting hole being transitionally fitted.

[0007] In one embodiment, a first flange is provided on the top surface of the upper plate, the first flange extends along the edge of the upper plate, and a second flange is formed on the top of the side plate, the second flange and the first flange are fitted together.

[0008] In one embodiment, the mounting plate protrudes in a direction away from the bottom longitudinal beam toward the anti-collision beam, forming a clearance portion. The side of the clearance portion facing the anti-collision beam forms a mounting groove, and the anti-collision beam passes through two of the mounting grooves.

[0009] In one embodiment, the sidewall of the mounting groove facing the anti-collision beam is in contact with the anti-collision beam, and the clearance portion is provided with a connection hole for connecting with the anti-collision beam.

[0010] In one embodiment, the mounting part includes a connecting body and a connecting plate. The connecting body is connected to the side of the upper plate, and the connecting plate is connected to the side of the connecting body away from the upper plate. The connecting plate is in contact with the column, and the connecting plate has mounting holes for connecting with the column.

[0011] In one embodiment, the mounting portion further includes a reinforcing plate, which is mounted on the side of the connecting body away from the column in a direction parallel to the upper plate.

[0012] In one embodiment, the included angle between the side plate and the mounting plate is defined as α; Therefore, α satisfies: 90°≤α≤120°.

[0013] This utility model also proposes a vehicle including an air intake duct structure as described in any of the above embodiments.

[0014] According to the technical solution of this utility model, the air intake guide structure includes a front frame, a crash beam, a flow guide assembly, and two bottom longitudinal beams. The front frame includes an upper curved beam, a lower curved beam, and two parallel columns. The two ends of each column are connected to the upper and lower curved beams, respectively. A first direction is defined as the direction from one column to the other. The two columns are connected to the two bottom longitudinal beams. The two ends of the crash beam are connected to the two bottom longitudinal beams. The flow guide assembly includes an upper guide plate and two side guide plates. The upper guide plate includes an upper plate and mounting portions installed on both sides of the upper plate along the first direction. The side guide plates include connected side plates and mounting plates. A through hole is formed at the top of the side plate, and the mounting portion passes through the through hole and connects to the column. The mounting plate is connected to the crash beam. By creating through holes in the side plates of the side deflectors, the mounting portion of the upper deflector can pass through these holes and connect to the columns on both sides. Furthermore, the mounting plate in the side deflectors connects to the anti-collision beam. This design avoids the need for excessively long cantilever arms connecting to the upper curved beam in both the upper and side deflectors. With this solution, when the height and width of the deflectors are smaller than the front frame dimensions, installation of each deflector can be achieved without excessively long cantilever arms, thus improving the stability of the installed deflectors. Simultaneously, the mounting portion passing through the through holes allows the upper deflector to provide constraint to the side deflectors, while the side deflectors provide supporting reaction force to the mounting portion, further enhancing the stability of the upper and side deflectors during installation.

[0022] The front end of a vehicle typically integrates a cooling system, including a matching cooling module and a spoiler, connected to the vehicle body via a front-end frame (including left and right pillars and upper and lower curved beams). In pure electric vehicles, the cooling module is smaller and mounted on the lower curved beam, while the front-end frame size usually remains unchanged to save costs. In this case, using the original-sized spoiler would result in material waste; using a smaller spoiler (meaning a spoiler whose height and width are smaller than the frame's height and width) would require a longer cantilever to connect to the upper curved beam. An excessively long cantilever increases the risk of breakage during vehicle operation, compromising the stability of the spoiler-frame connection.

[0023] According to the applicant's observations and research, if the same size air deflector as that used in traditional gasoline-powered vehicles continues to be used, given the reduced size of the cooling module in pure electric vehicles, the original size air deflector will not be able to fully perform its function. In some areas, the lack of practical use will result in material waste and unnecessary increased manufacturing costs. If a smaller air deflector is chosen—one whose height and width are smaller than the corresponding frame dimensions—a longer cantilever is required to connect it to the upper curved beam. However, increasing the cantilever length significantly alters its stress state. During daily vehicle use, the vibrations, impacts, and other external forces acting on the cantilever will be more complex, undoubtedly greatly increasing the risk of cantilever breakage. This makes it difficult to guarantee the stability of the connection between the air deflector and the frame, adversely affecting the overall performance and safety of the vehicle.

[0024] In view of this, the present invention proposes an air intake and air guiding structure to solve or at least alleviate the above problems.

[0025] Please see Figures 1 to 4 In one embodiment of this utility model, the air intake and air guiding structure includes a front frame 1, a crash beam 3, a flow guiding assembly 4, and two bottom longitudinal beams 2. The front frame 1 includes an upper curved beam 11, a lower curved beam 12, and two parallel columns 13. The two ends of each column 13 are connected to the upper curved beam 11 and the lower curved beam 12, respectively. The direction from one column 13 to the other column 13 is defined as the first direction (see [reference]). Figure 1 (in the left and right directions); two columns 13 are respectively connected to two bottom longitudinal beams 2; the two ends of the anti-collision beam 3 are respectively connected to two bottom longitudinal beams 2; the flow guiding assembly 4 includes an upper flow guiding plate 41 and two side flow guiding plates 42. The upper flow guiding plate 41 includes an upper plate 411 and mounting parts 412 installed on both sides of the upper plate 411 along the first direction. The side flow guiding plate 42 includes a connected side plate 421 and a mounting plate 422. A through hole is opened at the top of the side plate 421. The mounting part 412 passes through the through hole and is connected to the column 13. The mounting plate 422 is connected to the anti-collision beam 3.

[0026] In this embodiment, the upper curved beam 11, the lower curved beam 12, and the two columns 13 form a frame structure. The cooling module (not shown) is connected to this frame structure, thus requiring the installation of a deflector plate in the front frame 1 to allow external air to be introduced into the cooling module. In this embodiment, the through hole is a rectangular hole, and the shape of the mounting part 412 is adapted to the through hole to provide a fixed constraint to the side deflector plate 42, preventing displacement of the side deflector plate 42. The side deflector plate 42 is initially fixed by inserting the mounting part 412 into the through hole, and then fixed a second time by connecting the mounting plate 422 to the anti-collision beam 3. In this way, it is not necessary to set a cantilever in the side deflector plate 42 to connect with the front frame 1, and the stability of the side deflector plate 42 after installation can be improved. Since the upper guide plate 41 is connected to the column 13 via the mounting part 412 rather than to the upper curved beam 11 above the upper plate 411, the extension length of the mounting part 412 is shorter, which helps to improve the stability of the upper guide plate 41 after installation. In addition, after the side guide plate 42 is connected to the upper guide plate 41, the connection between the through hole and the mounting part 412 can also provide a certain support for the side guide plate 42 to the upper guide plate 41, avoiding excessive deformation and displacement of the upper guide plate 41 in the vertical direction. Thus, the stability of the upper guide plate 41 after installation can be further improved.

[0027] The technical solution of this embodiment involves creating a through hole in the side plate 421 of the side guide plate 42, allowing the mounting part 412 of the upper guide plate 41 to pass through the through hole and connect with the columns 13 on both sides. The mounting plate 422 of the side guide plate 42 is also connected to the anti-collision beam 3. This arrangement avoids the need for excessively long cantilever arms connecting to the upper curved beam 11 in the upper guide plate 41 and side guide plates 42. With this embodiment, when the height and width of the guide plates are smaller than the dimensions of the front frame 1, installation of each guide plate can be achieved without excessively long cantilever arms, thereby improving the stability of each guide plate after installation. Simultaneously, the mounting part 412 passing through the through hole allows the upper guide plate 41 to provide constraint to the side guide plate 42, while the side guide plate 42 can provide support reaction force to the mounting part 412, further improving the stability of the upper guide plate 41 and side guide plate 42 installation.

[0028] In one embodiment of this utility model, please refer to Figure 3The side plate 421 has locking holes, and the upper guide plate 41 also includes buckles 413 installed on both sides of the upper plate 411 along a first direction, which engage with the locking holes. In this embodiment, there are multiple locking holes and buckles 413, and they are arranged in a one-to-one correspondence. The upper guide plate 41 and the side plates 421 on both sides are provided with locking holes and buckles 413 for cooperation. Through the solution of this embodiment, the upper guide plate 41 and the side guide plate 42 can achieve a pre-assembly process. That is, before connecting the upper guide plate 41 and the side guide plate 42 to the front frame 1, the upper guide plate 41 and the side guide plate 42 are installed in advance in the assembly line to form pre-assembled parts. After the pre-assembled parts are transported to the assembly work area, the operator can directly connect the pre-assembled parts to the front frame 1 and the anti-collision beam 3. This setting is conducive to improving the efficiency of vehicle assembly and facilitating standardized management. In addition, the upper deflector 41 and the side deflector 42 are connected more stably by the engagement of the buckle 413 and the locking hole, thereby preventing the upper deflector 41 and the side deflector 42 from separating during vehicle use.

[0029] In one embodiment of this utility model, please continue reading. Figure 3 The side plate 421 also has limiting holes, and the upper guide plate 41 also includes limiting tongues 414 installed on both sides of the upper plate 411 along the first direction. The limiting tongues 414 are transitionally fitted with the limiting holes. In this embodiment, the limiting holes are rectangular holes, and the size of the limiting tongues 414 is adapted to the limiting holes so that after one end of the limiting tongues 414 passes through the limiting holes, the inner wall of the limiting holes and the outer peripheral sidewall of the limiting tongues 414 are in close contact with each other. In this way, when the upper guide plate 41 or the side guide plate 42 is subjected to external forces, such as airflow impact or vibration generated by vehicle movement, the tight fit between the limiting tongues 414 and the limiting holes can effectively limit the displacement of the upper guide plate 41 in the horizontal and vertical directions, preventing excessive offset, and helping to ensure that the upper guide plate 41 and the side guide plate 42 are always in a stable working position.

[0030] In one embodiment of this utility model, please refer to Figure 4The top surface of the upper plate 411 protrudes with a first flange 415, which extends along the edge of the upper plate 411. The top of the side plate 421 has a second flange 423, which fits into the first flange 415. In this embodiment, the fitting of the first flange 415 and the second flange 423 serves two purposes: firstly, the second flange 423 limits and supports the first flange 415, preventing excessive pressure from the upper plate 411 on the side plate 421 and causing deformation. Secondly, it increases the contact area between the upper plate 411 and the side plate 421, thereby improving the airtightness between them, reducing the probability of air leakage between the upper deflector 41 and the side deflector 42, and preventing airflow from entering the vehicle body through the gap between the upper plate 411 and the side plate 421. Ultimately, this improves the airflow guiding effect of the air intake structure.

[0031] In one embodiment of this utility model, please refer to Figure 1 The mounting plate 422 protrudes towards the anti-collision beam 3 away from the bottom longitudinal beam 2, forming a clearance portion 4221. A mounting groove 4222 is formed on the side of the clearance portion 4221 facing the anti-collision beam 3, and the anti-collision beam 3 passes through two mounting grooves 4222. Through this embodiment, after the side deflector 42 is connected to the anti-collision beam 3, it will not protrude excessively towards the front of the vehicle body, which is beneficial for the design and installation of front-end components (such as the front bumper, air intake grille, etc.). Furthermore, due to the presence of the clearance portion 4221, the structural rigidity of the side deflector 42 at the mounting groove 4222 is relatively low. When the vehicle body is subjected to a frontal collision, the mounting groove 4222 of the side deflector 42 can collapse promptly, guiding the side deflector 42 to undergo collapse deformation. Thus, the side deflector 42 provides the space required for pedestrian protection, reducing injury to pedestrians when the vehicle collides with them, and playing a role in protecting pedestrians.

[0032] In one embodiment of this utility model, the side wall of the mounting groove 4222 facing the anti-collision beam 3 is fitted to the anti-collision beam 3, and the clearance portion 4221 is provided with a connection hole for connecting with the anti-collision beam 3. By fitting the mounting groove 4222 to the anti-collision beam 3, the side guide plate 42 is made more stable during use. The connection hole is directly provided in the clearance portion 4221, allowing the part of the clearance portion 4221 to face the operator directly, enabling the operator to directly use tools to connect the clearance portion 4221 to the anti-collision beam 3, thus simplifying the installation process.

[0033] In one embodiment of this utility model, please refer to Figure 3 and Figure 4The mounting section 412 includes a connecting body 4121 and a connecting plate 4122. The connecting body 4121 is connected to the side of the upper plate 411, and the connecting plate 4122 is connected to the side of the connecting body 4121 away from the upper plate 411. The connecting plate 4122 is in close contact with the column 13, and the connecting plate 4122 has mounting holes for connecting with the column 13. The upper plate 411, the connecting body 4121, and the connecting plate 4122 are integrally formed, avoiding the possibility of wobbling due to seams in the upper guide plate 41. By making the connecting plate 4122 close to the column 13, the contact area between the upper guide plate 41 and the column 13 is increased. Bolts or clips 413 are passed through the mounting holes and connected to the column 13, making it easy to connect the upper guide plate 41 to the column 13. The position of the connecting plate 4122 makes it easy for the operator to fix it with bolts or clips 413, which helps to improve the installation efficiency of the upper guide plate 41. In this embodiment, the shape of the root of the connecting body 4121, that is, the through hole connection part between the connecting body 4121 and the side plate 421, is adapted to the shape of the through hole, so that the side plate 421 will not have excessive displacement relative to the connecting body 4121.

[0034] In one embodiment of this utility model, please refer to Figure 3 The mounting part 412 also includes a reinforcing plate 4123, which is installed on the side of the connecting body 4121 away from the column 13 in a direction parallel to the upper plate 411. The reinforcing plate 4123 provides support to the connecting body 4121, reduces the deformation of the connecting body 4121 in the direction of the front end of the vehicle body, and reduces the probability of the connecting body 4121 breaking, thereby further improving the stability of the upper deflector 41 and the side deflector 42 after installation.

[0035] In one embodiment of this utility model, the included angle between the side plate 421 and the mounting plate 422 is defined as α; then, α satisfies: 90°≤α≤120°. Preferably, 90°<α≤105°. For more details, please refer to [link to relevant documentation]. Figure 1 When α is greater than 90°, the side plate 421 tilts outwards towards the vehicle body in the left-right direction, causing the two side guide plates 42 to form a horn-shaped airflow cavity. This design can, on the one hand, expand the airflow range of the airflow cavity, increase the air intake to the cooling module, and optimize the cooling performance of the vehicle's cooling system. On the other hand, it can ensure that when the front of the vehicle collides with a pedestrian, the connection between the side plate 421 and the mounting plate 422 can break or deform in time, thereby improving the pedestrian protection effect.

[0036] This utility model also proposes a vehicle including an air intake duct structure. The specific structure of the air intake duct structure is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The vehicle also includes a cooling module connected to the front frame 1, and the upper guide plate 41 and the side guide plates 42 enclose a guide cavity, with the air inlet of the cooling module communicating with the guide cavity.

[0037] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
