Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a cooling duct, a cooling duct mounting assembly, and a vehicle. Background Technology

[0002] The brake disc is a crucial component of a vehicle's braking system. It is fixed to the wheel hub and rotates synchronously with the wheel. The quality of a vehicle's braking performance directly impacts its driving safety. During braking, the brake pads, pushed by the caliper pistons, compress the brake disc. The friction between the brake pads and the brake disc reduces the wheel's rotational speed, thus achieving braking. In related technologies, brake discs typically dissipate heat through their own cooling structures; however, these cooling solutions are complex in design and have limited heat dissipation capacity.

[0008] According to an embodiment of the present invention, the cooling duct allows airflow to enter the duct body through the air inlet and exit through the air outlet. Since the air outlet faces the brake disc, it can dissipate heat from the brake disc. Because the first mounting portion of the cooling duct has a snap-fit ​​cavity, the duct can be snapped into the corresponding locking mechanism on the vehicle during installation, thereby reducing the number of locking components and simplifying the installation process. Therefore, the cooling duct of this embodiment can effectively dissipate heat from the brake disc, and its simple structural design provides good heat dissipation.

[0018] In some embodiments, the duct body includes an air inlet section and an air outlet section. A first end of the air inlet section is connected to a first end of the air outlet section.

[0046] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] The following is a reference appendix. Figures 1 to 11 This invention describes a heat dissipation duct 1, a heat dissipation duct mounting assembly, and a vehicle according to embodiments of the present invention.

[0048] like Figures 1 to 4 As shown, the heat dissipation duct 1 of this utility model embodiment includes: a duct body 11 and a first mounting part 12. One end of the duct body 11 is provided with an air inlet 1111 and the other end of the duct body 11 is provided with an air outlet 1121. The air outlet 1121 is arranged toward the brake disc 3. The first mounting part 12 is provided on the outer wall of the duct body 11 and a snap-fit ​​cavity 1211 is provided in the first mounting part 12.

[0049] According to the embodiment of the present invention, the cooling duct 1 allows airflow to enter the duct body 11 through the air inlet 1111 and exit through the air outlet 1121. Since the air outlet 1121 faces the brake disc 3, it can dissipate heat from the brake disc 3, thereby improving the stability and safety of the braking system. Because the first mounting portion 12 of the cooling duct 1 has a snap-fit ​​cavity 1211, the cooling duct 1 can be snapped into the corresponding fitting on the vehicle through the snap-fit ​​cavity 1211 during installation, thereby reducing the number of locking components (e.g., bolts or pins) used and simplifying the installation method. Therefore, the cooling duct 1 of the present invention can dissipate heat from the brake disc 3, and its simple structural design provides good heat dissipation.

[0050] It is understandable that the snap-fit ​​cavity 1211 of the first mounting part 12 is used to mate with components surrounding the brake disc 3. For example, such as Figure 3 and Figure 4 As shown, the first mounting part 12 can be used in conjunction with the fastener 23 between the lower control arm 21 and the steering knuckle 22, that is, the fastener 23 is engaged with the snap-fit ​​cavity 1211.

[0051] In other examples, the snap-fit ​​cavity 1211 can be designed in accordance with the structure of the lower control arm 21 and the steering knuckle 22 so that the lower control arm 21 or the steering knuckle 22 can snap into the snap-fit ​​cavity 1211. Of course, the snap-fit ​​cavity 1211 can also be used in conjunction with other components, and this utility model does not limit this.

[0052] Compared to the solution where "the first mounting part 12 is connected to the lower control arm 21 or steering knuckle 22 by locking parts (e.g., bolts or pins)," the number of locking parts used can be reduced, and there is no need to drill holes in the lower control arm 21 or steering knuckle 22, thus avoiding affecting its structural strength. This is beneficial to improving the compatibility of the heat dissipation duct 1 and has a wider range of applications.

[0053] Optionally, such as Figures 7 to 10 As shown, the first mounting part 12 includes a fixing sleeve 121 and a limiting block 122. The fixing sleeve 121 is connected to the outer wall of the duct body 11. The snap-fit ​​cavity 1211 is located inside the fixing sleeve 121, and the limiting block 122 is located on the inner wall of the fixing sleeve 121 and protrudes inward along the radial direction of the fixing sleeve 121. It can be understood that one end of the limiting block 122 is connected to the inner wall surface of the fixing sleeve 121, and the other end of the limiting block 122 protrudes inward along the radial direction of the fixing sleeve 121. Thus, when the fastener 23 is inserted into the snap-fit ​​cavity 1211, the limiting block 122 can abut against the fastener 23, thereby further improving the stability of the first mounting part 12 after installation and making it less prone to loosening.

[0054] For example, the outer wall surface of the fastener 23 has threads, so that the limiting block 122 can abut against the threaded surface to increase the resistance of the fastener 23 to disengage from the snap-fit ​​cavity 1211, thereby further improving the stability and reliability of the connection between the first mounting part 12 and the fastener 23.

[0055] like Figure 8 and Figure 10 As shown, the limiting block 122 includes a first limiting block 1221 and a second limiting block 1222. The first limiting block 1221 and the second limiting block 1222 are arranged circumferentially along the fixed sleeve 121. The radial dimension of the first limiting block 1221 along the snap-fit ​​cavity 1211 is larger than the radial dimension of the second limiting block 1222 along the snap-fit ​​cavity 1211. The first limiting block 1221 can undergo elastic deformation under the action of external force.

[0056] It is understood that the radial dimension of the first limiting block 1221 is larger than the radial dimension of the second limiting block 1222. When the fastener 23 is inserted into the snap-fit ​​cavity 1211, the fastener 23 can squeeze the first limiting block 1221 to cause the first limiting block 1221 to undergo elastic deformation. As a result, the first limiting block 1221 can elastically abut against the outer wall surface of the fastener 23 to reduce the probability of the fastener 23 coming out of the snap-fit ​​cavity 1211.

[0057] When the first limiting block 1221 wears out or fails for other reasons, a second limiting block 1222 is also provided in the snap-fit ​​cavity 1211. The second limiting block 1222 can also limit the fastener 23 axially and circumferentially, thereby reducing the shaking amplitude of the fastener 23 relative to the snap-fit ​​cavity 1211. In other words, the first mounting part 12 of the heat dissipation duct 1 is provided with a first limiting block 1221 and a second limiting block 1222, which can provide double limiting for the fastener 23. Even if the first limiting block 1221 fails, the second limiting block 1222 can still normally constrain the position of the fastener 23, thereby improving the reliability of the heat dissipation duct 1 after installation.

[0058] Optionally, at least one of the first limiting block 1221 and the second limiting block 1222 may be multiple, and they may be arranged at intervals along the circumference of the locking cavity 1211. This can increase the contact area between the limiting block 122 and the fastener 23, and improve the locking firmness of the first mounting part 12.

[0059] For example, such as Figure 7 and Figure 10 As shown, there are multiple first limiting blocks 1221 and multiple second limiting blocks 1222, and the multiple first limiting blocks 1221 and multiple second limiting blocks 1222 are arranged alternately along the circumference of the snap-fit ​​cavity 1211.

[0060] Optionally, such as Figure 10 and Figure 11 As shown, the first mounting part 12 also includes a first reinforcing rib 123, which is connected to the fixing sleeve 121 and the duct body 11. This can improve the firmness of the connection between the first mounting part 12 and the duct body 11, and reduce the probability of breakage at the connection between the first mounting part 12 and the duct body 11, as well as the probability of air leakage due to cracks at the connection between the first mounting part 12 and the duct body 11.

[0061] For example, there may be multiple first reinforcing ribs 123, and the multiple first reinforcing ribs 123 are arranged at intervals in the vicinity of the fixing sleeve 121.

[0062] Optionally, such as Figure 9 and Figure 11As shown, the duct body 11 includes an air inlet section 111 and an air outlet section 112. The first end of the air inlet section 111 is connected to the first end of the air outlet section 112. The air inlet 1111 is located at the second end of the air inlet section 111, and the air outlet 1121 is located at the second end of the air outlet section 112. The first mounting part 12 is located on the outer wall of the air outlet section 112. Because the first mounting part 12 is located on the outer wall of the air outlet section 112, the first mounting part 12 can be close to the connection position between the steering knuckle 22 and the lower control arm 21, that is, the first mounting part 12 is close to the fastener 23 between the steering knuckle 22 and the lower control arm 21, thereby facilitating the use of the first mounting part 12 in conjunction with the fastener 23 and improving the rationality of the arrangement of the first mounting part 12.

[0063] In addition, since the first mounting part 12 is located on the outer wall of the air outlet section 112, the installation accuracy of the air outlet section 112 can be improved, the shaking amplitude of the air outlet section 112 when the vehicle is running can be reduced, which is conducive to improving the air outlet and heat dissipation effect of the heat dissipation duct 1.

[0064] In some embodiments, such as Figure 4 and Figure 11 As shown, the heat dissipation duct 1 also includes a second mounting portion 13, which includes an ear seat 131 disposed on the outer wall of the duct body 11. The ear seat 131 has a mounting hole 1311 for the connector 16 to pass through. By providing the second mounting portion 13, the heat dissipation duct 1 of this embodiment can further improve the installation stability of the heat dissipation duct 1. In addition, since the ear seat 131 of the second mounting portion 13 has a mounting hole 1311 for the connector 16 to pass through, the installation method of the second mounting portion 13 is simple and easy to manufacture.

[0065] For example, the lower control arm 21 is provided with a corresponding through hole (not shown), and the connector 16 passes through the mounting hole 1311 and the through hole to fix the second mounting part 13 to the lower control arm 21. The connector 16 can be a bolt or a pin.

[0066] like Figure 4 and Figure 11 As shown, the duct body 11 includes an air inlet section 111 and an air outlet section 112. The first end of the air inlet section 111 is connected to the first end of the air outlet section 112. The air inlet 1111 is located at the second end of the air inlet section 111, and the air outlet 1121 is located at the second end of the air outlet section 112. The ear seat 131 is located on the outer wall of the air inlet section 111. Since the ear seat 131 (second mounting part 13) is located on the outer wall of the air inlet section 111, the installation accuracy of the air inlet section 111 can be improved, the swaying amplitude of the air inlet section 111 when the vehicle is in motion can be reduced, and the air intake efficiency of the cooling duct 1 can be improved.

[0067] like Figure 11As shown, the second mounting part 13 also includes a second reinforcing rib 132, which is connected to the ear seat 131 and the duct body 11. This can improve the firmness of the connection between the ear seat 131 and the duct body 11, and reduce the probability of breakage at the connection between the ear seat 131 and the duct body 11, as well as the probability of air leakage due to cracks at the connection between the ear seat 131 and the duct body 11.

[0068] For example, there may be multiple second reinforcing ribs 132, and the multiple second reinforcing ribs 132 are arranged at intervals in the vicinity of the ear seat 131.

[0069] In some embodiments, such as Figure 5 and Figure 6 As shown, the heat dissipation duct 1 also includes a stop portion 14, which is disposed on the outer wall of the duct body 11 and is used to abut against the lower control arm 21 of the heat dissipation duct mounting assembly. By providing the stop portion 14, the heat dissipation duct 1 of this embodiment can be positionally constrained, thereby improving the stability of the connection between the heat dissipation duct 1 and the lower control arm 21 and ensuring the fixing effect of the heat dissipation duct 1.

[0070] Optionally, such as Figure 5 and Figure 6 As shown, the stop portion 14 includes a first stop block 141 and a second stop block 142. The first stop block 141 and the second stop block 142 are arranged at intervals along the extension direction of the duct body 11, and the first stop block 141 and the second stop block 142 are located on the upper and lower sides of the lower control arm 21, respectively. It can be understood that the first stop block 141 and the second stop block 142 are arranged alternately along the extension direction of the duct body 11 and in the vertical direction of the duct body 11. This can improve the overall fixing effect of the heat dissipation duct 1, and the structural design is simple and easy to assemble.

[0071] For example, such as Figure 11 As shown, the positions of the first stop block 141 and the second stop block 142 can also be reinforced with ribs to improve the structural strength of the area near the first stop block 141 and the second stop block 142.

[0072] In some embodiments, such as Figure 7 As shown, the duct body 11 includes an air inlet section 111 and an air outlet section 112. The first end of the air inlet section 111 is connected to the first end of the air outlet section 112. The air inlet 1111 is located at the second end of the air inlet section 111, and the air outlet 1121 is located at the second end of the air outlet section 112. In the direction from the first end of the air inlet section 111 to the second end of the air inlet section 111, the cross-sectional area (i.e., the air outlet cross-sectional area) of the air inlet section 111 gradually increases. In the direction from the first end of the air outlet section 112 to the second end of the air outlet section 112, the cross-sectional area (i.e., the air outlet cross-sectional area) of the air outlet section 112 gradually increases.

[0073] Understandably, both the inlet section 111 and the outlet section 112 are generally conical in shape, which facilitates drafting during the production of the duct body 11, thus simplifying its manufacturing process. Furthermore, since the cross-sectional area (i.e., the outlet cross-sectional area) of the inlet section 111 gradually increases from its first end to its second end, the airflow into the cooling duct 1 can be increased. Similarly, since the cross-sectional area (i.e., the outlet cross-sectional area) of the outlet section 112 gradually increases from its first end to its second end, the uniformity of the airflow from the cooling duct 1 can be improved, thereby enhancing its heat dissipation effect.

[0074] Optionally, such as Figure 7 As shown, there is a preset angle between the extending direction of the air intake section 111 and the extending direction of the air outlet section 112. It can be understood that the air intake duct does not extend in a straight line. Because there is a preset angle between the extending direction of the air intake section 111 and the extending direction of the air outlet section 112, the cooling duct 1 can avoid spatial interference at the connection point of the air intake section 111 and the air outlet section 112, thus facilitating the arrangement of the vehicle's suspension system or other components and improving space utilization.

[0075] like Figure 7 As shown, the heat dissipation duct 1 also includes a third reinforcing rib 15, which is located on the outer wall of the duct body 11 and is positioned at the connection between the air inlet section 111 and the air outlet section 112. This strengthens the structure at the connection between the air inlet section 111 and the air outlet section 112, reducing the deformation of the duct body 11 under external forces and ensuring the airflow guiding effect of the heat dissipation duct 1.

[0076] Optionally, such as Figure 7 As shown, the air inlet 1111 includes a first air inlet zone 11111 and a second air inlet zone 11112, with the openings of the first air inlet zone 11111 and the second air inlet zone 11112 facing different directions. This means that airflow can enter the first air inlet zone 11111 and the second air inlet zone 11112 in different directions. This increases the range of airflow entering the heat dissipation duct 1, which is beneficial for improving heat dissipation efficiency.

[0077] For example, the first air intake zone 11111 is arranged facing forward, and the second air intake zone 11112 is arranged facing downward. That is, the first air intake zone 11111 is arranged facing the front of the vehicle, so that airflow can enter the first air intake zone 11111 in a front-to-back direction. The second air intake zone 11112 is arranged facing the bottom of the vehicle, so that airflow can enter the second air intake zone 11112 in a bottom-to-up direction.

[0078] Since part of the air intake 1111 is arranged facing the front of the vehicle and the other part of the air intake 1111 is arranged facing the lower side of the vehicle, the air intake efficiency of the air intake 1111 can be improved, and the impact on the wind resistance of the whole vehicle is small.

[0079] For example, such as Figure 7 As shown, the structure of the first air intake zone 11111 is roughly U-shaped.

[0080] Optionally, the duct body 11 is a one-piece molded part, which allows for better sealing of the internal flow channels. Compared to a solution where the duct body 11 is a spliced ​​part, this avoids air loss, improves the air guiding efficiency of the duct body 11, and provides better heat dissipation. For example, the heat dissipation duct 1 is a one-piece injection molded part.

[0081] In this example of the utility model, the heat dissipation duct 1 can be made of PA66-GF35 material, so that the heat dissipation duct 1 has the advantages of high temperature resistance, high wear resistance and high strength.

[0082] like Figures 1 to 4 As shown, another embodiment of the heat dissipation duct installation assembly of the present invention includes: heat dissipation duct 1, lower control arm 21, steering knuckle 22 and fastener 23. The heat dissipation duct 1 is the heat dissipation duct 1 of the present invention. The lower control arm 21 and steering knuckle 22 are connected by fastener 23. One end of fastener 23 is snapped into the snap-fit ​​cavity 1211.

[0083] It is understandable that fastener 23 is connected to lower control arm 21 and steering knuckle 22 so that lower control arm 21 and steering knuckle 22 can rotate relative to each other. Since one end of fastener 23 is snapped into the snap-fit ​​cavity 1211, the cooling duct 1 can be fixed by the structure of the suspension system itself, which can save the number of locking parts used and is convenient for installation and disassembly.

[0084] According to the heat dissipation duct installation assembly of this utility model, airflow can enter the duct body 11 through the air inlet 1111 and exit through the air outlet 1121. Since the air outlet 1121 is arranged facing the brake disc 3, it can dissipate heat from the brake disc 3. Since the first mounting part 12 of the heat dissipation duct 1 is provided with a snap-fit ​​cavity 1211, the heat dissipation duct 1 can be snapped with the fastener 23 through the snap-fit ​​cavity 1211 during installation, thereby reducing the number of locking parts used and simplifying the installation method. Therefore, the heat dissipation duct installation assembly of this utility model can dissipate heat from the brake disc 3, and has a simple structural design and good heat dissipation effect.

[0085] Optionally, such as Figure 1 and Figure 2As shown, the cooling duct mounting assembly also includes a wheel hub (not shown) and a brake disc 3. The brake disc 3 is connected to the steering knuckle 22 via the wheel hub, and the air outlet 1121 is arranged on one side of the brake disc 3 in the thickness direction. Because the air outlet 1121 is arranged on one side of the brake disc 3 in the thickness direction, interference between the cooling duct 1 and the components surrounding the brake disc 3 is avoided, and the contact area between the exhaust airflow and the brake disc 3 is increased, thereby improving the heat dissipation effect of the brake disc 3.

[0086] Optionally, such as Figure 1 and Figure 2 As shown, the distance between the air outlet 1121 and the brake disc 3 is L, where 20mm ≤ L ≤ 30mm. For example, L can be 20mm, 22mm, 24mm, 26mm, 28mm, or 30mm. The cooling duct mounting assembly of this embodiment, by maintaining a distance of at least 20mm between the air outlet 1121 and the brake disc 3, can prevent interference between the brake disc 3 and the cooling duct 1 when the vehicle is turning. Furthermore, it avoids the problem of the cooling duct 1 at the air outlet 1121 being scorched by the high temperature on the surface of the brake disc 3 due to the air outlet 1121 being too close to the brake disc 3, thus ensuring the service life of the cooling duct 1. Since the distance between the air outlet 1121 and the brake disc 3 is less than or equal to 30mm, effective heat dissipation can be achieved for the brake disc 3, improving its heat dissipation effect.

[0087] Another embodiment of the vehicle of this utility model includes the cooling duct 1 or cooling duct mounting assembly of this utility model. In the vehicle of this utility model embodiment, the cooling duct 1 can dissipate heat from the brake disc 3, and the structure is simple and the heat dissipation effect is good.

[0088] It should be noted that the cooling duct 1 can be arranged at the position of the brake disc 3 of the front wheel (left front wheel or right front wheel) of the vehicle, or at the position of the brake disc 3 of the rear wheel (left rear wheel or right rear wheel). This utility model does not limit this.

[0089] Optionally, such as Figure 1 As shown, the vehicle includes a floor guard plate 4, and the lower edge of the air inlet 1111 is lower than the floor guard plate 4. Therefore, when the vehicle is in motion, a portion of the airflow from the bottom of the vehicle can directly enter the air inlet 1111 to increase the airflow within the cooling duct 1, thereby improving the cooling effect of the brake disc 3.
