[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] Currently, engine cooling systems typically include a radiator, water pump, and related piping. These components are subjected to significant mechanical and thermal stresses during vehicle operation. The inventors discovered that in the event of a collision, because existing suspension brackets 100 are often integrated with the radiator, the entire bracket may be damaged in the event of a collision. The impact force may also damage the water chamber, leading to damage to critical components such as the radiator, resulting in radiator leaks and the entire cooling system failing to function properly. Furthermore, if the bracket needs replacement, the integrated design necessitates replacing the entire radiator; if maintenance of the cooling components is required, the entire cooling system must be disassembled, increasing repair costs and time.

[0036] For the reasons mentioned above, please refer to Figures 1-4 This embodiment provides a suspension bracket 100;

[0037] For details, please refer to Figure 1 The suspension bracket 100 includes a first connecting portion 110 and a second connecting portion 120; the first connecting portion 110 is connected to the second connecting portion 120, and the first connecting portion 110 is used to be detachably connected to the vehicle body, and the second connecting portion 120 is used to be detachably connected to the radiator assembly; wherein, an energy-absorbing portion 130 is disposed in the region of the first connecting portion 110 near the second connecting portion 120 or the region of the second connecting portion 120 near the first connecting portion 110.

[0038] Please refer to Figures 1-4 The working principle of the suspension bracket 100 is as follows:

[0039] The suspension bracket 100 includes a first connecting portion 110 and a second connecting portion 120. The first connecting portion 110 is connected to the second connecting portion 120, and the first connecting portion 110 is detachably connected to the vehicle body, while the second connecting portion 120 is detachably connected to the radiator assembly. Thus, by detachably connecting the first connecting portion 110 to the vehicle body and the second connecting portion 120 to the radiator assembly, the detachable connection can be made using threaded connectors, limit pins, or snap-fit ​​mechanisms, thereby improving installation efficiency and facilitating replacement and maintenance in the future.

[0040] Furthermore, since an energy-absorbing part 130 is provided in the area of ​​the first connecting part 110 near the second connecting part 120 or in the area of ​​the second connecting part 120 near the first connecting part 110, the energy-absorbing part 130 can absorb impact energy during a collision, thereby protecting the heat dissipation components.

[0041] Moreover, based on the above-mentioned structure of the energy-absorbing part 130, a weakened structural design is formed, so that when it is hit, most of the impact energy can be absorbed by the energy-absorbing part 130. After the energy-absorbing part 130 absorbs the impact energy, cracks or fractures will appear first at this location. At this time, only the suspension bracket 100 needs to be replaced, and the heat sink assembly does not need to be replaced, thereby reducing its maintenance cost and shortening the maintenance cycle.

[0042] In summary, the suspension bracket 100 is applied to the engine cooling system. It has a simple structure, is easy to install, and can protect the heat dissipation components by absorbing impact energy through the energy absorption part 130 during a collision. At the same time, its structural design that allows for detachable connection with the heat dissipation components and the vehicle body makes it easy to replace and maintain in the future, thereby shortening the maintenance cycle and reducing maintenance costs.

[0043] Further, please refer to Figures 1-4 In this embodiment, when the energy-absorbing part 130 is configured, its function is to protect the heat dissipation component by absorbing the energy during the collision process. On this basis, the energy-absorbing part 130 includes at least one energy-absorbing hole 131, which can absorb the impact energy by deforming at the energy-absorbing hole 131.

[0044] It should be noted that, in configuring the energy-absorbing part 130, this embodiment is described by taking the energy-absorbing part 130 as an example of being located in the area of ​​the first connecting part 110 near the second connecting part 120, and by taking the energy-absorbing part 130 as an example of including two energy-absorbing holes 131. Furthermore, in this embodiment, the energy-absorbing part 130 is configured as an energy-absorbing hole 131. In this way, the energy-absorbing hole 131 becomes a structural weakening point in the area of ​​the first connecting part 110 near the second connecting part 120. When the suspension bracket 100 is subjected to external force, the structural weakening point will be the first to undergo energy-absorbing deformation or breakage. Thus, when a vehicle equipped with this suspension bracket 100 encounters a collision, the suspension bracket 100 will absorb most of the impact energy. During the process of absorbing impact energy, the structure of the energy-absorbing part 130 plays the role of absorbing impact energy. Since the energy-absorbing part 130 adopts a weakened structural design, it will deform or break before other parts during the impact. After cracks or breaks appear in the area of ​​its energy-absorbing part 130 due to energy absorption, the function can be restored by removing the first connecting part 110 and the second connecting part 120 from the vehicle body and the heat dissipation assembly, respectively, and replacing them with new suspension bracket 100 modules. This ensures the safety of the vehicle in a collision accident and simplifies the maintenance process.

[0045] Therefore, based on the first connecting part 110 including the mounting hole 111, the mounting hole 111 is used to install the connector connected to the vehicle body, and the two energy-absorbing holes 131 of the energy-absorbing part 130 can be arranged at intervals around the center line of the mounting hole 111, and then arranged on both sides of the first connecting part 110 near the second connecting part 120, so as to uniformly absorb the impact energy during the collision process.

[0046] Furthermore, based on the structure equipped with energy-absorbing holes 131, it can absorb impact energy upon collision, and in the process, release stress through its own deformation or destruction, thereby protecting the heat dissipation components. Please refer to [reference needed]. Figure 4 Therefore, an arc-shaped groove 132 can be provided on the side wall of each energy-absorbing hole 131 near the second connecting part 120. By setting the arc-shaped groove 132, the energy-absorbing hole 131 can be guided to be damaged at the arc-shaped groove 132, that is, the energy-absorbing hole 131 is damaged at the position of the arc-shaped groove 132 on that side, thereby protecting the heat dissipation component. Moreover, when configuring the arc-shaped groove 132, the arc-shaped groove 132 can be extended along the center line direction of the mounting hole 111.

[0047] When configuring the energy-absorbing hole 131, it can adopt a rectangular or circular hole structure. When using a rectangular hole structure, it has two opposing sets of sidewalls, one of which is the first sidewall 133 and the second sidewall 134. When configuring the opposing first sidewall 133 and second sidewall 134, the first sidewall 133 is closer to the second connecting part 120, while the second sidewall 134 is farther from the second connecting part 120. This allows both the first sidewall 133 and the second sidewall 134 to be arc-shaped around the center line of the mounting hole 111. Furthermore, the first sidewall 133 and the second sidewall 134 are respectively provided with a first arc-shaped groove 135 and a second arc-shaped groove 136. In this way, both the first sidewall 133 and the second sidewall 134 of the energy-absorbing hole 131 are provided with groove structures that guide the energy-absorbing hole 131 to deform during energy absorption, thereby improving its energy absorption effect.

[0048] Furthermore, since the first sidewall 133 is located on the side of the energy-absorbing hole 131 facing the second connecting portion 120, the radius of the arc of the first arc groove 135 can be smaller than the radius of the arc of the second arc groove 136. The purpose is to enable the side of the energy-absorbing hole 131 closest to the second connecting portion 120 to undergo energy-absorbing deformation before the second sidewall 134.

[0049] Based on the structure of the energy-absorbing arc-shaped groove 132 configured in the energy-absorbing hole 131, in order to ensure that the structural strength of other areas of the first connecting portion 110 is higher than that of its energy-absorbing portion 130, so that the energy-absorbing portion 130 can absorb energy and deform before other positions of the first connecting portion 110 during a collision, the end face of the first connecting portion 110 is also configured with a first strip groove 112 and a second strip groove 113. The end face is one end along the center line of the mounting hole 111. The first strip groove 112 and the second strip groove 113 are both arranged around the center line of the mounting hole 111, and energy-absorbing holes 131 are distributed at intervals between the ends of the first strip groove 112 and the second strip groove 113. That is, by setting the first strip groove 112 and the second strip groove 113, the structural strength of the positions other than the energy-absorbing portion 130 can be increased.

[0050] Further, please refer to Figures 1-4 Based on the structure of the first connecting part 110 described above, the purpose of configuring the second connecting part 120 is to connect it to the heat dissipation component. Therefore, in order to facilitate its connection with the heat dissipation component, the second connecting part 120 includes a main body 121, a positioning block 122, and a connecting block 123.

[0051] The main body 121 is connected to the first connecting part 110; the positioning block 122 and the connecting block 123 are both connected to the main body 121 and are spaced apart from each other, and both extend in a direction away from the first connecting part 110.

[0052] The connecting block 123 has a mounting groove 124, and the connecting block 123 has a connecting hole 125 communicating with the mounting groove 124 on the side opposite to the positioning block 122; wherein, the connecting hole 125 is used for the connecting bolts connected to the radiator assembly to pass through, and the mounting groove 124 is used to accommodate the connecting nut that mates with the connecting bolts.

[0053] With the above-described structural configuration, the positioning blocks 122 and connecting blocks 123 arranged at intervals can be connected to the heat dissipation component. The connection can be made by plugging in and then fixing with bolts. In other embodiments, other fixing methods can also be used. For example, a hole structure for mounting fixing bolts and a pin hole structure for mounting fixing pins can be configured on the second connecting part 120.

[0054] Furthermore, during the bolt connection and fixing process, by cooperating the positioning block 122 and the connecting block 123 with the heat dissipation component, and after the connecting bolt passes through the heat dissipation component and the connecting hole 125, it can be fixed by cooperating with the connecting nut located in the mounting groove 124; and the mounting groove 124 is provided with at least one end baffle 126 and at least one side baffle 127. The end baffle 126 is used to abut against the end of the connecting nut, and the side baffle 127 is used to abut against the side of the connecting nut. Thus, the setting of the end baffle 126 and the side baffle 127 can prevent the connecting nut from moving around in the mounting groove 124, thereby improving the stability of the connection.

[0055] Based on the aforementioned suspension bracket 100, please refer to... Figures 1-4 This embodiment also provides an engine cooling system, which includes a radiator assembly and its mounting bracket 100; the radiator assembly is connected to the cantilever beam of the vehicle body through the mounting bracket 100.

[0056] Specifically, taking the water chamber in the heat dissipation component as an example, which is connected to the cantilever beam of the vehicle body through the suspension bracket 100, the first connecting part 110 is connected to the vehicle body, and then the second connecting part 120 is connected to the water chamber, so that the water chamber can be stably connected to the vehicle body.

[0057] Based on this, when encountering a collision, the energy-absorbing part 130 on its first connecting part 110 can absorb the impact energy, thereby preventing damage to the water chamber; and when the energy-absorbing part 130 of the suspension bracket 100 is damaged or broken due to energy absorption, a new suspension bracket 100 can be replaced, thus eliminating the need to replace the entire heat dissipation component, thereby reducing its maintenance cost and maintenance cycle.

[0058] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
