Description

Technical Field

[0001] This disclosure relates to the field of automotive parts technology, and in particular to a condenser mounting bracket and a vehicle. Background Technology

[0002] The condenser is a crucial component of an automotive cooling system, responsible for heat exchange. It connects to the vehicle's front-end module via mounting brackets. As a heat dissipation device, the condenser dissipates the heat generated by the refrigerant during compressor compression into the external space, transforming the high-temperature, high-pressure gas from the compressor into a medium-temperature, high-pressure gas. Currently, most electric vehicles mount their condensers on the front longitudinal beams and subframe, achieving the dynamic stiffness target set by CAE (Computer Aided Engineering). However, due to the presence of the engine in the front compartment of range-extended hybrid vehicles, the condenser layout requires redesign. Two mounting points are located on the left and right sides of the front-end module, resulting in extremely low average dynamic stiffness.

[0003] With the continuous development and progress of the automotive industry, the NVH (Noise, Vibration, Harshness) performance, safety performance, and durability and reliability of automobiles have gradually become more important. Among them, NVH performance directly affects the experience and purchasing desire of drivers and passengers. In order to make products more competitive, the importance of NVH performance in the future development of automobiles cannot be underestimated.

[0004] However, due to the poor strength and rigidity of the condenser mounting brackets in the relevant technologies, the dynamic rigidity of the mounting points between condensers is poor, which affects the NVH performance of the vehicle. Summary of the Invention

[0027] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0028] This disclosure provides a condenser mounting bracket with high dynamic stiffness at the connection point between the bracket and the condenser. The sidewalls and bottom wall of the first bracket form a first cavity, thus the first bracket is box-shaped, resulting in high stiffness and strength. Furthermore, the first and second sidewalls of the first bracket are connected to the front-end module of the vehicle, providing high connection strength between the first bracket and the front-end module. Similarly, the sidewalls and bottom wall of the second bracket form a second cavity, thus the second bracket is box-shaped, providing high stiffness and strength. Furthermore, the fifth and sixth sidewalls of the second bracket are connected to the front-end module, providing high connection strength between the second bracket and the front-end module. This enhances the dynamic stiffness of the connection point between the first and second brackets and the condenser, thereby improving the vehicle's NVH performance.

[0049] The condenser is a crucial component of an automotive cooling system, responsible for heat exchange. It connects to the vehicle's front-end module via mounting brackets. As a heat dissipation device, the condenser dissipates the heat generated by the refrigerant during compressor compression into the external space, transforming the high-temperature, high-pressure gas from the compressor into a medium-temperature, high-pressure gas. Currently, most electric vehicles mount their condensers on the front longitudinal beams and subframe, achieving the dynamic stiffness target set by CAE (Computer Aided Engineering). However, due to the presence of the engine in the front compartment of range-extended hybrid vehicles, the condenser layout requires redesign. Two mounting points are located on the left and right sides of the front-end module, resulting in extremely low average dynamic stiffness.

[0050] With the continuous development and progress of the automotive industry, the NVH (Noise, Vibration, Harshness) performance, safety performance, and durability and reliability of automobiles have gradually become more important. Among them, NVH performance directly affects the experience and purchasing desire of drivers and passengers. In order to make products more competitive, the importance of NVH performance in the future development of automobiles cannot be underestimated.

[0051] However, due to the poor strength and rigidity of the condenser mounting brackets in the relevant technologies, the dynamic rigidity of the mounting points between condensers is poor, which affects the NVH performance of the vehicle.

[0052] In view of the above-mentioned technical problems, this disclosure provides a condenser mounting bracket with high strength and rigidity, thereby resulting in high dynamic rigidity between condenser mounting points. The condenser mounting bracket provided in this disclosure will now be described by way of example.

[0053] like Figure 1 As shown, the condenser mounting bracket includes a first bracket 1 and a second bracket 2. The first bracket 1 includes a first side wall 11, a second side wall 12, a third side wall 13, a fourth side wall 14, and a first bottom wall 15 connected in sequence. The first side wall 11 and the second side wall 12 are connected to the front-end module, and the first bottom wall 15 is connected to one end of the top of the condenser. The second bracket 2 includes a fifth side wall 21, a sixth side wall 22, a seventh side wall 23, an eighth side wall 24, and a second bottom wall 25 connected in sequence. The fifth side wall 21 and the sixth side wall 22 are connected to the front-end module, and the second bottom wall 25 is connected to the other end of the top of the condenser.

[0054] The first sidewall 11, second sidewall 12, third sidewall 13, fourth sidewall 14, and first bottom wall 15 form a cavity, making the first support 1 a box-shaped support. The fifth sidewall 21, sixth sidewall 22, seventh sidewall 23, eighth sidewall 24, and second bottom wall 25 form a cavity, making the second support 2 a box-shaped support. Both the first support 1 and the second support 2 are self-welded components, thus avoiding stress concentration on the first support 1 and the second support 2, and also ensuring the bending and torsional resistance of the condenser mounting bracket, making the condenser mounting bracket less prone to deformation.

[0055] The first bracket 1 and the second bracket 2 are formed by injection molding, stamping, forging and other processes, and assembled by bolts, pins and shafts. The forming process is simple, the versatility is strong, and the platform can be realized, making the product more competitive in the market.

[0056] The technical solutions provided in the embodiments of this disclosure, such as Figure 1 and Figure 2As shown, the connection point between the condenser mounting bracket and the condenser has high dynamic stiffness. The side walls and bottom walls of the first bracket 1 form a first cavity, thus the first bracket 1 is box-shaped, giving it high stiffness and strength. Furthermore, the first side wall 11 and the second side wall 12 of the first bracket 1 are both connected to the front-end module of the vehicle, resulting in high connection strength between the first bracket 1 and the front-end module. Similarly, the side walls and bottom walls of the second bracket 2 form a second cavity, thus the second bracket 2 is box-shaped, giving it high stiffness and strength. Furthermore, the fifth side wall 21 and the sixth side wall 22 of the second bracket 2 are both connected to the front-end module, resulting in high connection strength between the second bracket 2 and the front-end module. This enhances the dynamic stiffness of the connection points between the first bracket 1, the second bracket 1, and the condenser, avoiding dynamic stiffness valleys near the first-order fan frequency range, effectively reducing the real-vehicle risk of insufficient dynamic stiffness at the condenser mounting point, thereby improving the vehicle's NVH performance and driver comfort.

[0057] In some examples, such as Figure 1 As shown, the second sidewall 12 includes a first sub-sidewall 121 and a second sub-sidewall 122. The bottom end of the first sub-sidewall 121 is connected to the first bottom wall 15. The second sub-sidewall 122 is bent at the top end of the first sub-sidewall 121 and extends in a direction away from the fourth sidewall 14, wherein the fourth sidewall 14 is opposite to the first sub-sidewall 121. The first sub-sidewall 121 is connected to the rear side of the front-end module, and the second sub-sidewall 122 is connected to the top side of the front-end module.

[0058] The first sub-side wall 121 is connected to the rear side of the front-end module, and the second sub-side wall 122 is connected to the top side of the front-end module by bolts, so that the second side wall 12 has mounting points for connection with the front-end module in both the Y and Z directions. This can strengthen the connection between the second side wall 12 and the front-end module, making the connection between the first bracket 1 and the front-end module more secure.

[0059] In some examples, such as Figure 1 As shown, the bottom end of the first sub-sidewall 121 has a protruding plate 1211, which is located below the first bottom wall 15 and is connected to the rear side of the front-end module. The protruding plate 1211 can be bolted to the rear side of the front-end module. The protruding plate 1211 can be integrally formed with the second sub-sidewall 122. This increases the number of mounting points between the condenser mounting bracket and the front-end module, resulting in a stronger connection between them.

[0060] In this way, the first bracket 1 has connection points in the X direction (the length direction of the first sidewall 11), the Y direction (the length direction of the second sidewall 12), and the Z direction (the height direction of the first sidewall 11). This provides sufficient connection strength between the first bracket 1 and the front-end module, allowing the first bracket 1 to be more firmly fixed to the front-end module, thereby improving the connection strength between the first bracket 1 and the condenser.

[0061] In some examples, such as Figure 1 As shown, the first sub-sidewall 121 has a rib 1212 that protrudes toward the fourth sidewall 14. The rib 1212 can strengthen the structural strength and rigidity of the first sub-sidewall 121, thereby further improving the connection strength between the first sub-sidewall 121 and the front-end module.

[0062] The two ends of the rib 1212 extend toward the second sub-side wall 122 and the first bottom wall 15, respectively, and the rib 1212 is located in the middle of the first sub-side wall 121.

[0063] In some examples, such as Figure 1 As shown, the second sub-sidewall 122 has two first bolt holes 1221. The second sub-sidewall 122 is connected to the top of the front-end module through the first bolt holes 1221. The second sub-sidewall 122 can be connected to the front-end module by a flow drill screw.

[0064] The specific location of the first bolt hole 1221 can be arranged according to the specific situation. For places that may conflict with the arrangement, the location of the first bolt hole 1221 can be adjusted to avoid conflict.

[0065] In some examples, such as Figure 1 As shown, the first sidewall 11 has bolt holes, allowing the first sidewall 11 to be connected to the front-end module via bolts or screws. Specifically, the connection between the first sidewall 11 and the front-end module can be achieved using flow drill screws.

[0066] In some examples, such as Figure 1 As shown, the heights of the third sidewall 13 and the fourth sidewall 14 are less than the heights of the first sidewall 11 and the second sidewall 12. Since the third sidewall 13 and the fourth sidewall 14 are not connected to the front-end module, their heights can be relatively low. This allows the first bracket 1 to function as a box-shaped bracket while also reducing its weight, thus avoiding excessive pressure exerted on the front-end module by the first bracket 1.

[0067] In some examples, such as Figure 1As shown, the fifth sidewall 21 has two bolt holes, allowing the fifth sidewall 21 to be connected to the front-end module via bolts or screws. Specifically, the fifth sidewall 21 can be connected to the front-end module using a flow drill screw. The two bolt holes can be positioned along the width direction (Y direction) of the fifth sidewall 21.

[0068] In some examples, such as Figure 2 As shown, the sixth sidewall 22 has two second bolt holes 221, through which the sixth sidewall 22 is connected to the rear side of the front-end module. The sixth sidewall 22 can be fixedly connected to the front-end module by using flow drill screws passing through the second bolt holes 211. The two second bolt holes 221 can be arranged along the height direction (Z direction) of the sixth sidewall 22.

[0069] In some examples, the thickness of the first bottom wall 15 is 2.5mm-3mm, and the thickness of the second bottom wall 25 is 2.5mm-3mm. In related technologies, the thickness of the condenser and its mounting surface is typically 1.5mm-2mm. In this embodiment, increasing the thickness of the first bottom wall 15 and the second bottom wall 25 to 2.5mm-3mm strengthens the rigidity of the first bottom wall 15 and the second bottom wall 25, thereby enhancing the connection strength between the first support 1, the second support 2, and the condenser.

[0070] The first bottom wall 15 and the second bottom wall 25 can be made by stamping. The size and thickness of the cross-section of the first bottom wall 15 and the second bottom wall 25 can be adjusted according to the stamping process, thereby increasing the rigidity of the first bottom wall 15 and the second bottom wall 25, thereby improving the installation strength of the first bracket 1 and the condenser, as well as the installation strength of the second bracket 2 and the condenser.

[0071] In some examples, such as Figure 2 As shown, the top of the fifth sidewall 21 of the second bracket 2 has a hook 211, which is connected to the front-end module to further strengthen the connection between the fifth sidewall 21 and the front-end module. The hook 211 is located in the middle of the top of the fifth sidewall 21, and the hook 211 is curved, bending towards the side of the fifth sidewall 21 away from the seventh sidewall 23.

[0072] On the one hand, the hook 211 increases the number of mounting points between the second bracket 2 and the condenser, thereby further strengthening the installation strength and dynamic rigidity between the second bracket 2 and the condenser. On the other hand, the hook 211 can serve as a pre-installation device between the second bracket 2 and the condenser, thus facilitating bolt connection between the second bracket 2 and the condenser.

[0073] In some examples, the first bottom wall 15 and / or the second bottom wall 25 have through holes. The through holes reduce the weight of the first bottom wall 15 and the second bottom wall 25. This reduces the force exerted by the first bracket 1 and the second bracket 2 on the front-end module and screws, preventing either the first bracket 1 or the second bracket 2 from detaching from the front-end module due to excessive weight. This allows the first bracket 1 and the second bracket 2 to be more stably fixed to the front-end module, thereby making the connection between the first bracket 1, the second bracket 2 and the condenser more stable.

[0074] Understandably, the through holes on the first bottom wall 15 and the second bottom wall 25 should be located in non-sensitive and unimportant areas to avoid damaging the rigidity and strength of the first bottom wall 15 and the second bottom wall 25, thereby affecting the rigidity and strength of the first support 1 and the second support 2. This allows the first support 1 and the second support 2 to have both high rigidity and light weight.

[0075] Compared to the previous condenser mounting bracket, such as Figure 1 and Figure 2 As shown, the present invention redesigns the simple mounting bracket with poor structural rigidity in related technologies into a box-type structure, and adds mounting points in both the X and Y directions, which can provide sufficient strength and rigidity, thereby significantly improving the dynamic rigidity of the mounting points. While improving the rigidity and strength of the first bracket 1 and the second bracket 2, the first bracket 1 and the second bracket 2 are also easy to disassemble, improving the durability and reliability of the vehicle body structure and making the product more competitive in the market.

[0076] Furthermore, the condenser mounting bracket provided in this embodiment is more rationally designed than previous designs. By adding ribs 1212 and adjusting the thickness of the mounting materials of the first bracket 1 and the second bracket 2, the dynamic stiffness and structural stability of the mounting points of the first bracket 1 and the second bracket 2 are further improved. Simultaneously, the design of openings in non-sensitive and unimportant areas of the first bracket 1 and the second bracket 2 achieves a weight reduction effect on the condenser mounting bracket. Moreover, the space occupied by existing components can be effectively avoided by adjusting the position of the mounting points; only new mounting points need to be added to the mounting bracket.

[0077] Meanwhile, the condenser mounting bracket provided in this embodiment has a simple structure and good versatility. Following this approach, similar condenser mounting brackets can be designed for different vehicle models, which can shorten the project development cycle and reduce costs.

[0078] This disclosure also provides a vehicle including the aforementioned condenser mounting bracket. The condenser mounting bracket is fixed to the front-end module of the vehicle and connected to the condenser.

[0079] Among them, the vehicle can be a range-extended hybrid vehicle.

[0080] The technical solution provided in this disclosure provides high dynamic stiffness between the connection point of the condenser mounting bracket and the condenser. The side walls and bottom walls of the first bracket 1 of the condenser mounting bracket form a first cavity, thus the first bracket 1 is box-shaped, giving it high stiffness and strength. Furthermore, the first side wall 11 and the second side wall 12 of the first bracket 1 are both connected to the front-end module of the vehicle, resulting in high connection strength between the first bracket 1 and the front-end module. Similarly, the side walls and bottom walls of the second bracket 2 of the condenser mounting bracket form a second cavity, thus the second bracket 2 is box-shaped, giving it high stiffness and strength. Furthermore, the fifth side wall 21 and the sixth side wall 22 of the second bracket 2 are both connected to the front-end module, resulting in high connection strength between the second bracket 2 and the front-end module. This enhances the dynamic stiffness of the connection points between the first bracket 1, the second bracket 1, and the condenser, avoiding the dynamic stiffness valley value being near the first-order rotational frequency range of the fan. This effectively reduces the risk of insufficient dynamic stiffness at the condenser mounting point in the actual vehicle, thereby improving the vehicle's NVH performance and enhancing driver comfort.

[0081] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
