[0005] In view of this, the purpose of the present invention is to provide a thermal management module installation structure and a vehicle to solve the problem that the working noise of the water pump in the existing thermal management module is easily transmitted to the passenger compartment, causing customer complaints.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A thermal management module installation structure includes a thermal management module, wherein the thermal management module is assembled and fixed to a vehicle body installation bracket through a shock absorbing component;

[0008] The shock absorbing assembly includes a bushing and a shock absorbing pad sleeved on the bushing, wherein the shock absorbing pad is formed with a shock absorbing portion at a position in contact with the bushing to prevent the vibration generated by the thermal management module from being transmitted to the vehicle body through the vehicle body mounting bracket.

[0009] According to the above technical means, the thermal management module is assembled and fixed to the vehicle body mounting bracket by using a shock absorbing assembly, and a shock absorbing part is arranged on the shock absorbing pad of the shock absorbing assembly, so that the vibration generated by the thermal management module is absorbed and blocked by the shock absorbing assembly, effectively blocking or reducing the working vibration noise generated by the thermal management module from being transmitted to the vehicle body through the vehicle body mounting bracket, thereby improving the comfort performance of the vehicle, thereby effectively solving the problem that the working noise of the water pump in the existing thermal management module is easily transmitted to the passenger compartment, causing customer complaints, and has the advantages of simple structure, easy assembly and low cost.

[0010] Preferably, the shock-absorbing pad is formed with a plurality of support protrusions at intervals at a portion in contact with the bushing, and the grooves formed between adjacent support protrusions together constitute the shock-absorbing portion.

[0011] By forming multiple supporting protrusions at intervals at the contact points between the shock-absorbing pad and the bushing, the multiple supporting protrusions play a role of stabilizing support, effectively ensuring the assembly stability of the shock-absorbing pad and the bushing, while also avoiding the problem of the bushing easily falling off during transportation; at the same time, the grooves formed between adjacent supporting protrusions effectively reduce or even block the working vibration noise generated by the thermal management module.

[0012] Preferably, the shock absorbing portion and the bushing are clearance-fitted.

[0013] Preferably, the supporting protrusion and the bushing are interference fit.

[0014] By controlling the shock absorbing part and the bushing to be a clearance fit, a vibration isolation space is formed between the shock absorbing pad and the bushing, thereby effectively reducing and blocking the transmission of the working vibration noise generated by the thermal management module; at the same time, the supporting protrusion and the bushing are controlled to be an interference fit, which avoids the risk of the shock absorbing assembly falling during transportation and ensures the stability of the assembly between the thermal management module and the vehicle body mounting bracket after assembly.

[0015] Preferably, the shock-absorbing pad is a shock-absorbing rubber pad.

[0016] Preferably, the bushing is a metal bushing.

[0017] Since the elasticity of the rubber pad itself can absorb part of the vibration energy, a shock-absorbing rubber pad is used as the shock-absorbing pad. Since the bushing is in direct contact with the fastener during the assembly process, a metal bushing is used as the bushing to ensure the stability of the assembly of the thermal management module and the body mounting bracket. If both the shock-absorbing pad and the bushing are made of rubber, there will be a problem of loose assembly.

[0018] Preferably, the thermal management module comprises a coolant flow channel plate, the coolant flow channel plate is provided with a mounting hole for assembling the shock absorbing assembly, and the mounting hole has an opening.

[0019] By arranging an opening on the mounting hole, the assembly of the shock absorbing component is effectively facilitated. At the same time, the shock absorbing component can be clamped and fixed on both sides of the opening of the mounting hole, further improving the stability of the assembly of the shock absorbing component.

[0020] Preferably, the mounting hole is a bar-shaped hole.

[0021] By setting the mounting hole as a strip hole, the shock-absorbing pad can move in the hole after the mounting hole is matched with the shock-absorbing pad, which effectively reduces the dimensional accuracy requirements for the vehicle body mounting bracket and facilitates fine-tuning of the assembly position of the thermal management module.

[0022] Preferably, at least four mounting holes are spaced apart on the coolant flow channel plate, and the openings of the mounting holes face away from the coolant flow channel plate.

[0023] By arranging at least four mounting holes at intervals on the coolant flow channel plate, the stability of the assembly of the thermal management module and the vehicle body mounting bracket is further ensured; at the same time, the opening direction of the mounting holes is set to be away from the coolant flow channel plate, which effectively avoids interference with adjacent components when assembling the shock absorbing assembly.

[0024] Preferably, the thermal management module further comprises a water pump assembly disposed on the coolant flow channel plate;

[0025] The water pump assembly includes a heating water pump, a motor water pump and a battery water pump;

[0026] The heating water pump is used to provide the vehicle with heat generated when the coolant flows;

[0027] The motor water pump is used to drive the coolant in the motor cooling circuit of the vehicle to flow in the coolant circuit channel;

[0028] The battery water pump is used to drive the coolant in the battery pack cooling circuit of the vehicle to flow in the coolant circuit channel.

[0029] Preferably, the thermal management module further comprises a battery circuit temperature sensor, an electric drive circuit temperature sensor and a multi-way control water valve arranged on the coolant flow channel plate;

[0030] The battery circuit temperature sensor is used to detect the coolant temperature in the battery pack cooling circuit;

[0031] The electric drive circuit temperature sensor is used to detect the coolant temperature in the motor cooling circuit;

[0032] The multi-way control water valve is used to switch multiple cooling liquid circuit channels.

[0033] The utility model also provides a vehicle, comprising the installation structure of the thermal management module of the utility model.

[0034] Beneficial effects of the utility model:

DETAILED DESCRIPTION

[0041] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0042] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0043] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. Example

[0044] like Figures 1 to 4 As shown, a thermal management module installation structure includes a thermal management module 1, and the thermal management module 1 is assembled and fixed to a vehicle body mounting bracket through a shock absorbing component 2;

[0045] The shock absorbing assembly 2 includes a bushing 21 and a shock absorbing pad 22 sleeved on the bushing 21 . The shock absorbing pad 22 is formed with a shock absorbing portion 221 at a position in contact with the bushing 21 to prevent the vibration generated by the thermal management module 1 from being transmitted to the vehicle body through the vehicle body mounting bracket.

[0046] The thermal management module is assembled and fixed to the vehicle body mounting bracket by using a shock absorbing assembly, and a shock absorbing part is provided on the shock absorbing pad of the shock absorbing assembly, so that the vibration generated by the thermal management module is absorbed and blocked by the shock absorbing assembly, so as to block or reduce the working vibration noise generated by the thermal management module from being transmitted to the vehicle body through the vehicle body mounting bracket, so that the working vibration noise is further transmitted to the passenger compartment through the vehicle body, thereby improving the comfort performance of the vehicle and solving the problem that the working noise of the water pump in the existing thermal management module is easily transmitted to the passenger compartment, causing customer complaints.

[0047] Among them, it has been proved through experiments that by forming a shock-absorbing part at the contact point between the shock-absorbing pad and the bushing, compared with the ordinary rubber pad without a shock-absorbing part, the working vibration noise generated by the thermal management module can be greatly reduced or even blocked from being transmitted to the vehicle body, thereby reducing or blocking the vibration noise transmitted to the passenger compartment and improving the riding comfort performance of the passengers.

[0048] In some embodiments, in order to ensure the stability of the assembly of the shock-absorbing pad and the bushing, and to prevent the bushing from falling off during transportation before the shock-absorbing assembly is assembled on the vehicle bracket, a plurality of support protrusions 222 are formed at intervals at the contact portion between the shock-absorbing pad 22 and the bushing 21, and the grooves formed between adjacent support protrusions 222 together constitute the shock-absorbing portion 221. It can be understood that the shock-absorbing portion 221 is a gap between adjacent support protrusions 222, and the air between the gaps has a very low efficiency in transmitting vibration noise energy. At the same time, the contact area between the support protrusion 222 and the outer wall of the bushing 21 is very small, which also makes the transmission of vibration noise very difficult. The two together play the purpose of reducing vibration noise. When the air between the gaps is replaced by vacuum, the transmission efficiency of vibration noise energy will be lower, thereby achieving the purpose of blocking vibration noise.

[0049] In some embodiments, in order to effectively reduce and block the transmission of working vibration noise generated by the thermal management module, the shock absorbing part 221 and the bushing 21 are set to be a clearance fit; at the same time, in order to avoid the risk of the shock absorbing assembly easily falling during transportation, and to ensure the stability of the assembly of the thermal management module and the vehicle body mounting bracket after assembly, therefore, the support protrusion 222 and the bushing 21 are set to be an interference fit.

[0050] Exemplarily, the shock-absorbing pad 22 is similar to a cylindrical structure, and a plurality of supporting protrusions 222 are formed at intervals on the inner hole wall of the shock-absorbing pad 22 , and grooves formed between adjacent supporting protrusions 222 together constitute a shock-absorbing portion 221 .

[0051] Exemplarily, a corrugated structure is formed on the inner hole wall of the shock-absorbing pad 22 along the circumferential direction, the crests of the corrugated structure are supporting protrusions 222, the crests of the corrugated structure and the outer circle of the bushing 21 are interference fit, the troughs of the corrugated structure are grooves, and the troughs of the corrugated structure together constitute the shock-absorbing part 221, and the troughs of the corrugated structure and the outer circle of the bushing 21 are clearance fit.

[0052] Exemplarily, the wave crests of the corrugated structure are in line contact with the outer circumferential wall of the bushing 21, thereby further reducing the noise transmission efficiency.

[0053] Exemplarily, the wave crests of the corrugated structure are further provided with grooves at intervals along the axial direction of the shock absorbing pad 22, that is, the linear support protrusions 222 formed along the axial direction of the shock absorbing pad 22 are further provided with grooves at intervals along the length direction of the support protrusions 222, so that the wave crests of the corrugated structure are in point contact with the outer circumferential wall of the bushing 21, which can further reduce the noise transmission efficiency.

[0054] In some embodiments, since the elasticity of the rubber pad itself can absorb a portion of the vibration energy, a shock-absorbing rubber pad is used as the shock-absorbing pad 22 .

[0055] In some embodiments, since the bushing is in direct contact with the fastener during the assembly process, in order to ensure the stability of the assembly of the thermal management module and the vehicle body mounting bracket, a metal bushing is used as the bushing 21 .

[0056] In some embodiments, the thermal management module 1 includes a coolant flow channel plate 11, and a mounting hole 111 for assembling the shock absorbing assembly 2 is provided on the coolant flow channel plate 11. In order to facilitate the assembly of the shock absorbing assembly, an opening structure is provided at the edge of the mounting hole 111. It has been proved in practice that after the opening structure is provided at the edge of the mounting hole 111, it can be assembled directly without the use of tooling assistance, which greatly simplifies the assembly process, improves the assembly efficiency, and reduces the cost. At the same time, the two end surfaces of the opening structure can also realize the clamping and fixing of the shock absorbing assembly, which can improve the assembly stability of the drag reduction assembly.

[0057] In some embodiments, the mounting hole 111 is set as a strip hole, so that after the mounting hole and the shock-absorbing pad are matched, the shock-absorbing pad can move in the hole, thereby reducing the dimensional accuracy requirements for the vehicle body mounting bracket and facilitating fine-tuning of the assembly position of the thermal management module.

[0058] In some embodiments, in order to avoid interference between the shock absorbing assembly and adjacent components during assembly, at least four mounting holes 111 are provided on the coolant channel plate 11 at intervals, and the openings of the mounting holes 111 face away from the coolant channel plate 11 .

[0059] Among them, under normal circumstances, the overall structure of the coolant flow channel plate 11 is similar to a rectangular structure. Therefore, at least four mounting holes 111 are set, that is, at least one mounting hole 111 is set in each corner, which ensures the uniformity of the overall force of the coolant flow channel plate 11, thereby ensuring the stability of the thermal management module after being assembled on the vehicle body mounting bracket.

[0060] In some embodiments, the thermal management module 1 further includes a water pump assembly 12 disposed on the coolant flow channel plate 11;

[0061] The water pump assembly 12 is used to drive the coolant in the vehicle to flow in the coolant circuit channel.

[0062] In some embodiments, the water pump assembly 12 includes a heating water pump 121 , a motor water pump 122 , and a battery water pump 123 .

[0063] Exemplarily, the heating water pump 121 is used to provide the vehicle with heat generated when the coolant flows.

[0064] Exemplarily, the motor water pump 122 is used to drive the coolant in the motor cooling circuit of the vehicle to flow in the coolant circuit channel.

[0065] Exemplarily, the battery water pump 123 is used to drive the coolant in the battery pack cooling circuit of the vehicle to flow in the coolant circuit channel.

[0066] In some embodiments, the thermal management module 1 further includes a battery circuit temperature sensor 13 , an electric drive circuit temperature sensor 14 and a multi-way control water valve 15 arranged on the coolant flow channel plate 11 .

[0067] Exemplarily, the battery circuit temperature sensor 13 is used to detect the temperature of the coolant in the battery pack cooling circuit.

[0068] Exemplarily, the electric drive circuit temperature sensor 14 is used to detect the coolant temperature in the motor cooling circuit.

[0069] Exemplarily, the multi-way control water valve 15 is used to switch multiple cooling liquid circuit channels.

[0070] In some embodiments, a vehicle is further provided, comprising the mounting structure of the thermal management module in the above embodiments.

[0071] To sum up, the installation structure of the thermal management module and the vehicle of the utility model, by using a shock-absorbing assembly to assemble and fix the thermal management module to the vehicle body mounting bracket, and at the same time providing a shock-absorbing part on the shock-absorbing pad of the shock-absorbing assembly, so that the vibration generated by the thermal management module is absorbed and blocked by the shock-absorbing assembly, effectively blocking or reducing the working vibration noise generated by the thermal management module from being transmitted to the vehicle body through the vehicle body mounting bracket, thereby improving the comfort performance of the vehicle, thereby effectively avoiding the problem of working vibration noise being transmitted from the vehicle body to the interior of the passenger compartment, causing customer complaints, and having the advantages of simple structure, easy assembly and low cost, and having promotion and application value in the field of automotive thermal management system technology.
