In addition, since the functions of some parts between the components provided in the above embodiments are the same, the specification adopts a unified naming method for these parts. The pipe fitting connecting device provided by the related technical scheme has been described in detail above, and the specific embodiments are applied in this paper. The above embodiment description is only used to help understand the method of the application and its core idea, and does not limit the application in any form.

[0026] As Figure 1As shown, the present application provides an all-terrain vehicle 100, which includes a frame 11, a body covering 12, a suspension system 13, a running system 14. The body covering 12 covers at least part of the frame 11, and the body covering 12 includes but is not limited to an engine hood, a luggage compartment cover, a door, a fender, a body side, a roof, etc. The suspension system 13 is connected between the frame 11 and the running system 14, for transmitting the force and torque between the frame 11 and the running system 14, and reducing the vibration of the vehicle body during driving due to uneven road surface. The running system 14 is at least partially located below the frame 11, for supporting the all-terrain vehicle 100. In order to clearly illustrate the technical solutions of the present application, the up-down, left-right and front-rear directions of the all-terrain vehicle 100 are also provided as shown in the accompanying drawings. Figure 1

[0027] It should be noted that, in the following description of the all-terrain vehicle 100, the height direction of the frame 11 is parallel to the up-down direction of the all-terrain vehicle 100, the width direction of the frame 11 is parallel to the left-right direction of the all-terrain vehicle 100, and the length direction of the frame 11 is parallel to the front-rear direction of the all-terrain vehicle 100.

[0028] As shown in the accompanying drawings, Figure 2 The frame 11 constitutes the basic framework of the all-terrain vehicle 100, and the frame 11 includes a rear frame 111, a middle frame 112 and a front frame 113. The front frame 113, the middle frame 112 and the rear frame 111 are arranged in order from front to rear along the length direction of the frame 11 and are integrally formed, and the rear frame 111 surrounds a receiving space 101.

[0029] The all-terrain vehicle 100 further includes a power assembly 15 and a cooling system 16. The power assembly 15 is at least partially disposed in the receiving space 101 and fixedly connected with the rear frame 111. The power assembly 15 is a collection of a series of components for generating power and transmitting the power to the road surface, including an engine, a transmission and connecting components therebetween. The cooling system 16 is installed on the rear frame 111. The cooling system 16 is used to control the temperature of the engine. During operation of the engine, a large amount of heat is released due to fuel combustion, causing the internal temperature to rise rapidly. The cooling system 16 can timely remove the excess heat and accurately control the working temperature of the engine within a suitable range.

[0030] As shown in the accompanying drawings, Figure 3 ​As shown, as an implementation manner, the cooling system 16 comprises an intercooler 161, a radiator 162 and a connecting bracket 163. The power assembly 15 is configured with a turbo device (not shown in the figure), and high-temperature supercharged air of the turbo device first enters the intercooler 161, and the high-temperature supercharged air exchanges heat with external cold air through the intercooler 161 to reduce the temperature of the supercharged air. The radiator 162 is used for heat exchange with the intercooler 161. The intercooler 161 and the radiator 162 are both mounted on the connecting bracket 163, and are connected with the rear frame 1111 through the connecting bracket 163, and the connecting bracket 163 is at least partially arranged in the accommodation space 101.

[0031] Exemplarily, the connecting bracket 163 is an integral frame which is detachably connected with the rear frame 111. The intercooler 161 and the radiator 162 can be respectively mounted on the connecting bracket 163 through fasteners, and after the intercooler 161 and the radiator 162 are fixed on the connecting bracket 163, the connecting bracket 163 is connected with the corresponding mounting structure on the rear frame 111 to realize integrated mounting of the intercooler 161 and the radiator 162.

[0032] In other examples, the intercooler 161 and the radiator 162 are fixedly connected, and after being fixed, the intercooler 161 or the radiator 162 is connected with the connecting bracket 163, and the connecting bracket 163 is connected with the corresponding mounting structure on the rear frame 111 to realize integrated mounting of the intercooler 161 and the radiator 162.

[0033] Further, the connecting bracket 163 is arranged above the power assembly 15, and at least partially overlaps the power assembly 15 in the height direction of the frame 11.

[0034] In the all-terrain vehicle 100 provided by the embodiments of the present application, the intercooler 161 and the radiator 162 are arranged in the accommodation space 101 through the connecting bracket 163 and above the power assembly 15. The vehicle body cover 12 comprises a vehicle body side wall 121 (see Figure 1 ), and the vehicle body side wall 121 is provided with an air inlet 1211 facing the front of the all-terrain vehicle 100, and the intercooler 161 has a windward surface 1611 facing the middle frame 112. During vehicle driving, cold air enters the accommodation space 101 from the air inlet 1211 and impacts the windward surface 1611. High-temperature supercharged air of the engine enters the inside of the intercooler 161 and flows through the heat dissipation fins of the intercooler 161. The cold air flows through the surface of the heat dissipation fins, so that the heat on the surface of the heat dissipation fins is continuously taken away, and finally the cooling of the high-temperature supercharged air is realized.

[0035] Through the above arrangement, the modular design of the cooling system 16 is realized, and the integrated installation of the cooling system 16 is facilitated. Since the connecting bracket 13 is arranged as an integral frame, the structural strength of the connecting bracket 13 is improved. In addition, during the arrangement of the whole vehicle, since the intercooler 161 and the radiator 162 are integrated on the connecting bracket 163, only the mounting structure needs to be arranged at the corresponding position on the rear frame 111 for fixing the connecting bracket 163, so as to facilitate the adjustment of the positions of the intercooler 161 and the radiator 162 in the accommodation space 101.

[0036] Compared with the related art, the intercooler is arranged on the front frame. However, in the embodiment of the present application, the cooling system 16 is arranged on the rear frame 111, which can also reduce the obstruction to the front view and provide a better front view for the driver and the passenger.

[0037] As shown in Figure 3 As an implementation manner, a height direction reference plane 102 perpendicular to the frame 11 is defined, and when the intercooler 161 is installed on the rear frame 111 through the connecting bracket 163, the included angle γ between the windward surface 1611 and the reference plane 102 ranges from 0° to 90°. Further, the included angle γ ranges from 0° to 80°. More preferably, the included angle γ ranges from 0° to 70°. It should be noted that if the included angle γ is too large, the cold air after passing through the air inlet 1211 is not uniformly contacted with the windward surface 1611, and the cooling effect of the intercooler 161 on the high-temperature pressurized air is poor. If the included angle is too small, a more complex air duct needs to be arranged for guiding the cold air entering from the air inlet 1211 to the windward surface 1611, which on the one hand occupies too much accommodation space 101 when the cooling system 16 is arranged, and on the other hand increases the cost of the cooling system 16. Through the above arrangement, the intercooler 161 is arranged more reasonably, the cold air passing through the air inlet 1211 can be uniformly contacted with the windward surface 1611, and the cooling effect of the intercooler 161 is improved.

[0038] As shown in Figure 4 As an implementation manner, the rear frame 111 includes a rear upper transverse pipe 1111 and a cargo box support beam 1112 connected with the rear upper transverse pipe 1111, wherein the rear upper transverse pipe 1111 extends along the width direction of the frame 11, and the cargo box support beam 1112 is arranged behind the rear upper transverse pipe 1111, and both of them are arranged above the accommodation space 101. The rear upper transverse pipe 1111 has two upper transverse pipe mounting portions 1111a distributed along the width direction of the frame 11, and the cargo box support beam 1112 has two cargo box support beam mounting portions 1112a distributed along the width direction of the frame 11, and the connecting bracket 163 is connected with the rear frame 111 through the upper transverse pipe mounting portions 1111a and the cargo box support beam mounting portions 1112a.

[0039] Exemplarily, the two upper transverse pipe mounting portions 1111a and the two cargo box support beam bracket mounting portions are each provided as a sheet metal member.

[0040] As shown in Figure 5 and Figure 6 Further, the connecting bracket 163 includes a frame 1631, a first bracket mounting member 1632, a second bracket mounting member 1633, a radiator mounting member 1634, and an intercooler mounting member 1635. The frame 1631 constitutes a main body of the connecting bracket 163. The first bracket mounting member 1632, the second bracket mounting member 1633, the radiator mounting member 1634, and the intercooler mounting member 1635 are each provided on an outer surface of the frame 1631. The frame 1631 is connected to the rear upper transverse pipe 1111 via the first bracket mounting member 1632. The frame 1631 is connected to the cargo box support beam 1112 via the second bracket mounting member 1633. The radiator mounting member 1634 is configured to connect the radiator 162. The intercooler mounting member 1635 is configured to connect the intercooler 161.

[0041] Specifically, the connecting bracket 163 has two first bracket mounting members 1632, which are distributed above the frame 1631 in the width direction of the vehicle frame 11. Taking one of the first bracket mounting members 1632 as an example, the first bracket mounting member 1632 is provided in a tubular structure. One end of the first bracket mounting member 1632 is connected to the frame 1631, and the other end is connected to the rear upper transverse pipe 1111. The end of the first bracket mounting member 1632 that is away from the frame 1631 is detachably connected to the upper transverse pipe mounting portion 1111a.

[0042] The connecting bracket 163 has two second bracket mounting members 1633, which are distributed on the left and right sides of the frame 1631 in the width direction of the vehicle frame 11. Taking the second bracket mounting member 1633 on either side of the frame 1631 as an example, one end of the second bracket mounting member 1633 is connected to the frame 1631, and the other end is connected to the cargo box support beam 1112. The end of the second bracket mounting member 1633 that is away from the frame 1631 is detachably connected to the cargo box support beam mounting portion 1112a.

[0043] The connecting bracket 163 has two heat sink mounting members 1634 arranged below the frame 1631 in the width direction of the vehicle frame 11, the heat sink mounting members 1634 are connected with the heat sink 162 and support the heat sink 162 in the height direction of the vehicle frame 11. Optionally, the heat sink 162 is provided with two auxiliary mounting members 1636 arranged above the frame 1631 in the width direction of the vehicle frame 11, the heat sink 162 is limited in the height direction of the vehicle frame 11 by the auxiliary mounting members 1636 and the heat sink mounting members 1634 arranged on the upper and lower sides of the heat sink 162 respectively, and the connection stability between the heat sink 162 and the connecting bracket 163 is improved. In addition, since the arrangement positions of the heat sink mounting members 1634 and the auxiliary mounting members 1636 are different, the directions of the pre-tightening forces applied by the fasteners connecting the heat sink mounting members 1634 and the heat sink 162 and the fasteners connecting the auxiliary mounting members 1636 and the heat sink 162 are different, further improving the connection stability between the heat sink 162 and the connecting bracket 163.

[0044] The intercooler mounting members 1635 are distributed on the left and right sides of the frame 1631, and since the heat sink 162 is closer to the connecting bracket 163 than the intercooler 161, the intercooler mounting members 1635 on both sides of the frame 1631 also have a tendency to extend towards the intercooler 161, so that the intercooler mounting members 1635 can abut against the intercooler 161, avoiding the heat sink 162 while improving the connection stability between the intercooler 161 and the connecting bracket 163.

[0045] As shown in Figure 5 Further, the frame 1631 surrounds the mounting space 103, and the heat sink 162 at least partially passes through the mounting space 103, thereby shortening the length of the cooling system 16 in the length direction of the vehicle frame 11, minimizing the space occupied by the cooling system 16, and optimizing the layout of the cooling system 16.

[0046] Exemplarily, the side of the heat sink 162 away from the intercooler 161 is provided with a fan 1621, and when the heat sink 162 is installed on the connecting bracket 163, the fan 1621 passes through the mounting space 103 surrounded by the frame 1631.

[0047] As shown in Figure 5 and Figure 6As shown, as an implementation manner, the first bracket mounting member 1632 at least includes two first fixing portions 1632a connected with the rear upper cross pipe 1111, and the first fixing portions 1632a are located at one end of the first bracket mounting member 1632 away from the frame 1631. When the first bracket mounting member 1632 is connected with the rear upper cross pipe 1111, the two first fixing portions 1632a are connected with the two upper cross pipe mounting portions 1111a respectively by fasteners, and the length interval between the two first fixing portions 1632a in the width direction of the vehicle frame 11 is defined as a first length L1, wherein the first length L1 is the interval length between the axes of the two fasteners connecting the upper cross pipe mounting portion 1111a and the first fixing portion 1632a.

[0048] According to the above, the connecting bracket 163 has two radiator mounting members 1634 arranged below the frame 1631, and the length interval between the two radiator mounting members 1634 in the width direction of the vehicle frame 11 is defined as a second length L2, wherein the second length L2 is the interval length between the axes of the two fasteners connecting the radiator mounting member 1634 and the radiator 162.

[0049] The second bracket mounting member 1633 has a second fixing portion 1633a connected with the cargo box support beam 1112, and the second fixing portion 1633a is located at one end of the second bracket mounting member 1633 away from the frame 1631. When the second bracket mounting member 1633 is connected with the cargo box support beam 1112, the two second fixing portions 1633a are connected with the two cargo box support beam mounting portions 1112a respectively by fasteners, and the length interval between the two second fixing portions 1633a in the width direction of the vehicle frame 11 is defined as a third length L3, wherein the third length L3 is the interval length between the axes of the two fasteners connecting the cargo box support beam mounting portion 1112a and the second fixing portion 1633a.

[0050] In the embodiments of the present application, the first length L1 is less than the second length L2, and the second length L2 is less than the third length L3. Through the above arrangement, the structure of the connecting bracket 163 presents a stable triangular configuration, and such structure itself has high bending stiffness and deformation resistance, can make the load of the upper cross pipe mounting portion 1111a, the cargo box support beam mounting portion 1112a and the radiator mounting member 1634 uniformly distributed, avoid stress concentration points, improve the deformation resistance of the overall structure, and further improve the stiffness of the connecting bracket 163.

[0051] As shown in FIG. 6, the connecting bracket 163 is arranged on the frame 1631, and the connecting bracket 163 is arranged on the frame 1631 in a manner of being arranged on the frame 1631 and extending along the width direction of the vehicle frame 11. Figure 6As shown, in one implementation, the orthographic projection of one first bracket mounting member 1632 on the reference plane 102 extends substantially along a first direction, and the orthographic projection of the other first bracket mounting member 1632 on the reference plane 102 extends substantially along a second direction. The angle α between the first and second directions ranges from 0° to 90°. Further, the angle α ranges from 0° to 80°. More preferably, the angle α ranges from 0° to 70°. It should be noted that the rear frame 111 includes a rear shock absorber mounting member 1113, which is located at the junction of the rear upper cross tube 1111 and the cargo box support beam 1112. The rear shock absorber of the all-terrain vehicle 100 is connected to the rear shock absorber mounting member 1113, and the force generated by the rear shock absorber can be applied to the rear frame 111 through the rear shock absorber mounting member 1113. Since the position of the first bracket mounting part 1632 connected to the frame 1631 is fixed, and its end facing away from the frame 1631 is connected to the upper horizontal tube mounting part 1111a through the first fixing part 1632a, the range of the included angle α determines the setting position of the two upper horizontal tube mounting parts 1111a. If the included angle α is too large, the distance between the upper horizontal tube mounting part 1111a and the rear shock absorber mounting part 1113 will be too small. During vehicle operation, due to the uneven distribution of force and torque transmitted from the rear shock absorber to the rear frame 111, the load on both sides of the rear upper horizontal tube 1111 will be large, which may affect the connection stability between the rear frame 111 and the connecting bracket 163. If the included angle α is too small, the distance between the two upper horizontal tube mounting parts 1111a will be too small, and the load applied by the connecting bracket 163 to the rear upper horizontal tube 1111 will be more concentrated, increasing the risk of deformation of the rear upper horizontal tube 1111. With the above configuration, the force and torque transmitted by the rear shock absorber during vehicle operation can be evenly distributed in the rear upper horizontal tube 1111, and the pressure applied by the cooling system 16 can be evenly distributed in the rear upper horizontal tube 1111, thereby improving the stability of the rear frame 111.

[0052] As one implementation, along the width direction of the frame 11, the length of the rear upper cross tube 1111 is defined as the fourth length L4 (see...). Figure 4), the ratio of the fourth length L4 to the first length L1 ranges from 2 to 4 when the fourth length L4 is fixed. Further, the ratio ranges from 2.5 to 3.5. More preferably, the ratio is 3. It should be noted that if the ratio is too small, the spacing between the upper cross pipe mounting portion 1111a and the rear shock absorber mounting member 1113 is too small. During vehicle driving, due to uneven distribution of force and torque transmitted by the rear shock absorber to the rear frame 111, the load on both sides of the rear upper cross pipe 1111 is large, which may affect the stability of the connection between the rear frame 111 and the connecting bracket 163. If the ratio is too large, the spacing between the two upper cross pipe mounting portions 1111a is too small, and the load applied by the connecting bracket 163 on the rear upper cross pipe 1111 is concentrated, increasing the risk of deformation of the rear upper cross pipe 1111. Through the above arrangement, the force and torque transmitted by the rear shock absorber during vehicle driving can be evenly distributed on the rear upper cross pipe 1111, and the pressure applied by the cooling system 16 can be evenly distributed on the rear upper cross pipe 1111, thereby improving the stability of the rear frame 111.

[0053] In summary, by arranging the connecting bracket 163, the intercooler 161 and the radiator 162 are integrated and mounted on the connecting bracket 163, and the connecting bracket 163 is connected to the rear frame 111, thereby realizing the modular design of the cooling system 16, facilitating the integrated installation of the cooling system 16. Since the connecting bracket 163 is arranged as a monolithic frame, the structural strength of the connecting bracket 163 is improved. In addition, during the overall vehicle arrangement, since the intercooler 161 and the radiator 162 are integrated on the connecting bracket 163, only the mounting structure (such as the upper cross pipe mounting portion 1111a and the cargo box support beam mounting portion 1112a described above) needs to be arranged on the rear frame 111 at the corresponding position to fix the connecting bracket 163, thereby facilitating the adjustment of the position of the intercooler 161 and the radiator 162 in the accommodation space.
