[0034] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] In the description of the present disclosure, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present disclosure.

[0036] With the development of intelligent mining, two-way driving technology has facilitated the application of unmanned driving technology and improved the equipment attendance rate, which is one of the main trends in the development of mining car technology. However, the two-way driving mining car in the relevant technology still has insufficient thermal management level, especially the cooling system of the vehicle is difficult to meet the cooling requirements of the whole machine when driving in reverse.

[0037] The present disclosure provides a two-way driving vehicle that can travel in two directions (e.g., forward and backward) without turning around, and can be used as a mining vehicle or a special vehicle, for example, a mining vehicle, and can be used in working scenarios such as narrow lanes. The present disclosure improves the heat dissipation system of the vehicle, and can achieve effective whole machine thermal management under two-way driving conditions.

[0038] refer to Figure 1 and Figure 2As shown, in some embodiments of the two-way driving vehicle provided by the present disclosure, the two-way driving vehicle includes a power system 1, a radiator 2 and an isolation device 3. The radiator 2 is used to dissipate heat for the power system 1. The radiator 2 includes a heat dissipation core 21 and an air supply device 22, the heat dissipation core 21 is fluidly connected to the power system 1, and the air supply device 22 is configured to drive the airflow to flow through the heat dissipation core 21 to dissipate heat for the heat dissipation core 21, wherein the flow direction of the airflow is opposite to the driving direction of the two-way driving vehicle. The isolation device 3 is arranged between the power system 1 and the radiator 2, and the isolation device 3 has an open state that allows the airflow to pass through and a closed state that blocks the airflow from passing through. When the airflow flows from the side of the heat dissipation core 21 away from the power system 1 to the side of the heat dissipation core 21 close to the power system 1, the isolation device 3 is configured to be in an open state, and when the airflow flows from the side of the heat dissipation core 21 close to the power system 1 to the side of the heat dissipation core 21 away from the power system 1, the isolation device 3 is configured to be in a closed state.

[0039] In the disclosed embodiment, the power system 1 may be an engine, a battery or other components used to drive the vehicle, or a power device used to drive the operating equipment on the vehicle. By providing a radiator 2 to dissipate heat from the power system 1, the operating reliability and safety of the power system 1 can be effectively guaranteed, and its operating efficiency can be guaranteed.

[0040] Here, a cooling medium may be arranged in the heat dissipation core 21 for circulation, and the cooling medium may exchange heat with the power system 1 through a heat exchange pipeline. The cooling medium may be gas or liquid.

[0041] As an example, in a vehicle equipped with an engine supercharging system, the heat dissipation core 21 may include a first core for providing heat dissipation for the engine cylinder block, and a second core for providing heat dissipation for the high-temperature gas after the engine supercharging. For example, the first core may be a water-cooled heat dissipation core, and the second core may be an intercooled heat dissipation core (which may be an air-cooled or water-cooled core). The first core and the second core may be installed independently of each other to meet the cooling requirements of the gas in the engine cylinder block and the intercooler, respectively, to achieve differentiated heat dissipation, and to improve the thermal management accuracy of the whole machine.

[0042] In the disclosed embodiment, the direction of the airflow flowing through the heat dissipation core 21 is opposite to the direction of travel of the vehicle (regardless of whether it is traveling forward or reverse), that is, the airflow field formed by the air supply device 22 is consistent with the direction of the airflow field generated by the vehicle's travel, thereby effectively avoiding flow field turbulence caused by the conflict between the two directions.

[0043] In one example, when a bidirectional vehicle is traveling forward, Figure 1As shown, the vehicle travels from right to left (the speed is shown as +v), and the flow field formed by the movement of the vehicle is shown by the solid arrow in the figure, that is, the flow flows from left to right in the figure. In this case, the air supply device 22 is provided to provide a flow field flowing from left to right, which can not only avoid flow field conflicts, but also form a superposition of flow fields in the same direction, increase the surface wind speed of the heat dissipation core 21, and thus improve the heat dissipation efficiency of the radiator 2.

[0044] Among them, the isolation device 3 is set to be in an open state when the vehicle is traveling forward, so that the airflow from the radiator 2 can further flow through the isolation device 3 to the space where the power system 1 is located, which helps to expand the flow area of ​​the airflow and improve the flow smoothness of the airflow, thereby helping to improve the heat dissipation efficiency of the radiator 2.

[0045] In another example, when a bidirectional vehicle is traveling in the opposite direction, Figure 2 As shown, the vehicle travels from left to right (speed is shown as -v), and the flow field formed by the vehicle movement is shown by the dotted arrows in the figure, that is, flowing from right to left in the figure. In this case, the air supply device 22 is set to provide a flow field flowing from right to left.

[0046] The isolation device 3 is in a closed state when the vehicle is traveling in the reverse direction, and physically isolates the high-temperature gas on the power system 1 from flowing back to the radiator 2 , thereby preventing the heat dissipation efficiency of the radiator 2 from decreasing.

[0047] In the disclosed embodiment, there are multiple optional schemes for the specific setting form of the air supply device 22. For example, the air supply device 22 can be a fan with forward and reverse rotation functions, and the direction of the flow field provided by it can be changed by changing the direction of the fan. Alternatively, the air supply device 22 can be a centrifugal blower with variable inlet and outlet, and the air flow path therein can be changed by switching the direction of the inlet and outlet air valves. Alternatively, the air supply device 22 can also adopt the setting of opposed double fan groups, that is, a unidirectional axial flow fan is arranged on each side of the heat dissipation core 21, which is responsible for air supply when the vehicle is traveling forward and reverse respectively.

[0048] In one embodiment of the present disclosure, the air supply device 22 includes an axial flow fan that can rotate forward and reverse, and the axial flow fan is arranged between the heat dissipation core 21 and the isolation device 3. By changing the direction of the axial flow fan, when the vehicle is traveling forward, air can be sucked from the outside of the radiator 2 to the inside of the radiator 2, thereby forming an airflow that flows from the heat dissipation core 21 to the axial flow fan and then to the power system 1; or when the vehicle is traveling in the reverse direction, air can be blown from the axial flow fan to the outside of the radiator 2, thereby forming an airflow that flows from the axial flow fan to the heat dissipation core 21 and then to the outside of the radiator 2.

[0049] refer to Figure 2As shown, in some embodiments, the radiator 2 further includes a guide cover 23, which is used to guide the gas to flow into the interior of the radiator 2, or to guide the airflow to flow out of the radiator 2. The flow field design can also be performed to optimize the matching relationship and flow channel structure between the air supply device 22 and the guide cover 23, thereby improving the balance of the two-way flow of the airflow.

[0050] In some embodiments, the two-way vehicle further includes a power compartment 4, and the power system 1, the radiator 2 and the isolation device 3 are all arranged in the power compartment 4. The power compartment 4 and the first side of the isolation device 3 form a first compartment for accommodating the radiator 2, and the power compartment 4 and the second side of the isolation device 3 form a second compartment for accommodating the power system 1. The first compartment and / or the second compartment are provided with exhaust holes 401.

[0051] As an example, refer to Figure 2 As shown, the power compartment 4 can be surrounded by a frame 41 and a hood 42 of a two-way driving vehicle. The power compartment 4 can form a relatively closed space for shielding and protecting the heat dissipation and power system of the vehicle. The power compartment 4 is separated into a first compartment and a second compartment independently of each other by an isolation device 3, so that the radiator 2 can be isolated from the power system, which is convenient for thermal management of the vehicle under different operating conditions. For example, as mentioned above, under the forward and reverse driving conditions, by changing the opening and closing state of the isolation device 3, the first compartment and the second compartment can be fluidically connected, or the fluid connection between the first compartment and the second compartment can be blocked, thereby ensuring the heat dissipation efficiency of the radiator 2 under different driving conditions. Among them, the first side of the isolation device 3 can be Figure 2 The second side of the isolating device 3 may be Figure 2 The side facing the power system 1.

[0052] By providing the exhaust hole 401 on the power compartment 4 , the fluidity of the gas in the power compartment 4 can be improved, the discharge of hot air can be promoted, and the heat dissipation effect of the radiator 2 can be enhanced.

[0053] The exhaust hole 401 may be arranged on the side wall of the power compartment 4, for example Figure 1 and Figure 2 As shown, a plurality of exhaust holes 401 are provided on the side wall of the hood 42. When the side walls of the first cabin and the second cabin are both provided with exhaust holes 401, when the vehicle is traveling forward, Figure 1 As shown, part of the gas sucked from the front of the vehicle by the radiator 2 can be discharged through the exhaust holes 401 on the side wall of the first cabin, and the other part can also be discharged through the exhaust holes 401 on the side wall of the second cabin, effectively improving the exhaust efficiency of hot air. Figure 2As shown, the air supply device 22 operates to form a negative pressure inside the first cabin, thereby driving the gas outside the vehicle to flow into the power cabin 4 from the exhaust hole 401 on the side wall of the first cabin, and further pass through the radiator core 21, taking away the heat on the radiator core 21, and further discharged from the outlet of the radiator 2 on the side away from the power system 1.

[0054] Alternatively, the exhaust hole 401 can be arranged at the top of the power cabin 4, using the rising effect of hot air to accelerate the exhaust of high-temperature gas. An air inlet can also be opened at the bottom of the power cabin 4 to form a "low in and high out" chimney effect, improve the fluidity of the airflow in the power cabin 4, and reduce the risk of flow field turbulence.

[0055] In some embodiments, the bidirectional vehicle further includes a first control unit 5 , which is signal-connected to the air supply device 22 , and the first control unit 5 is configured to control the air supply direction and / or air supply speed of the air supply device 22 .

[0056] The first control unit 5 can control the action of the air supply device 22 based on the instructions or signals it receives, for example, controlling the air supply direction of the air supply device 22 based on the received signal of the vehicle switching the driving direction, or adjusting the air supply speed of the air supply device 22 based on the received engine temperature signal.

[0057] In some embodiments, the bidirectional vehicle further includes a second control unit 6 , which is signal-connected to the isolation device 3 , and the second control unit 6 is configured to control the opening and closing of the isolation device 3 .

[0058] The second control unit 6 can control the action of the isolation device 3 based on the instructions or signals it receives, for example, it can control the isolation device 3 to open when receiving a signal that the vehicle is traveling in the forward direction (using the airflow generated by traveling to assist in heat dissipation), and control the isolation device 3 to close when receiving a signal that the vehicle is traveling in the reverse direction (blocking heat reflux).

[0059] By setting up a control unit to control the actions of the air supply device 22 and the isolation device 3, it is helpful to improve the level of automation control of bidirectional vehicles, thereby efficiently maintaining the flow field stability of the entire vehicle, especially the cooling system, and adapting to the automation and intelligent transformation of bidirectional vehicles.

[0060] In some embodiments of the present disclosure, the driving direction of the vehicle may be measured by a speed sensor.

[0061] For example, in Figure 3 In some of the embodiments shown, the two-way moving vehicle also includes a first sensor 7 for detecting the driving direction of the two-way moving vehicle, and the first control unit 5 is connected to the signal of the first sensor 7 to control the air supply direction of the air supply device 22 according to the detection result of the first sensor 7.

[0062] In such Figure 3 In some other embodiments shown, the second control unit 6 is signal-connected to the first sensor 7 to control the opening and closing of the isolation device 3 according to the detection result of the first sensor 7 .

[0063] The first control unit 5 and the second control unit 6 can be arranged independently or integrated into a unified control module. For example, the first control unit 5 and the second control unit 6 can be integrated with the control system of the whole vehicle to simplify the layout of the control system of the whole vehicle.

[0064] In addition to adjusting the actions of the air supply device 22 and the isolation device 3 according to the driving direction of the vehicle, they can also be adjusted according to the temperature of key components of the vehicle. For example, the air supply speed of the air supply device 22 and the opening degree of the isolation device 3 can be adjusted according to the engine cylinder temperature, the cooling water temperature, etc., to obtain a good thermal management effect.

[0065] In some embodiments of the present disclosure, the bidirectional driving vehicle further includes a second sensor 8 for detecting the temperature of the radiator 2 and / or the power system 1 .

[0066] In some examples, a second sensor 8 may be provided to detect relevant temperature data of the power system 1, and its specific installation position may be set according to actual detection requirements. For example, the second sensor 8 may be installed on the cylinder head of the engine to detect the cylinder temperature of the engine, or the second sensor 8 may be installed at the exhaust pipe of the engine to measure its exhaust temperature.

[0067] In other examples, a second sensor 8 may be provided to detect relevant temperature data of the radiator 2, and its specific installation position may be set according to actual detection requirements. For example, the second sensor 8 may be installed on the cooling water pipeline of the radiator 2 to detect the temperature of the cooling water circulating in the water cooling structure of the radiator 2, or the second sensor 8 may be installed on the air inlet or outlet of the radiator 2 to measure the temperature of the gas entering and exiting the radiator 2.

[0068] In some other examples, the second sensor 8 can be configured to include a first detection module and a second detection module. The first detection module can be installed at the power system 1 (for example, at the cylinder head or exhaust pipe mentioned above) to detect relevant temperature data of the power system 1; the second detection module is installed at the radiator 2 (for example, at the cooling water pipeline mentioned above or at the air inlet and outlet of the radiator) to detect relevant temperature data at the radiator 2.

[0069] In some embodiments, the first control unit 5 is signal-connected to the second sensor 8 to control the air supply speed of the air supply device 22 according to the detection result of the second sensor 8 .

[0070] As an example, when the temperature detected by the second sensor 8 is higher, the first control unit 5 can correspondingly increase the air supply speed of the air supply device 22 to accelerate heat dissipation by strengthening convection. For example, the air supply device 22 (such as a fan) can be set to have multiple speeds, and when the temperature of the cooling water increases by a preset temperature (such as 20°C) or a preset ratio (such as 10%), the first control unit 5 increases the fan speed by one level.

[0071] In a specific example, the power system 1 includes an engine, the radiator 2 includes a water cooling core for dissipating heat from the engine cylinder, the air supply device 22 includes a fan, and the second sensor 8 is used to detect the temperature of the cooling water of the engine. The cooling water of the engine circulates in the cooling water flow channel between the engine cylinder and the radiator.

[0072] The fan can be set to have a minimum speed and a maximum speed. When the cooling water temperature of the engine is lower than 82°C, the first control unit 5 controls the fan to rotate at the minimum speed. When the cooling water temperature of the engine is higher than 92°C, the first control unit 5 controls the fan to rotate at the maximum speed. When the cooling water temperature is at other temperatures between the above two, the fan can be set to have corresponding speed gears (for example, five gears corresponding to five different temperatures). The first control unit 5 controls the fan to increase the speed according to the gears based on the increase in the cooling water temperature.

[0073] Here, the fan speeds at different gears may be set in proportion, for example, corresponding to the proportion of the change in the engine cooling water temperature.

[0074] In some other examples, if the power system 1 includes other heat-generating components besides the engine, the speed level of the fan may be set according to the actual operating temperature requirements of the heat-generating components with reference to the control method described in the above example.

[0075] In some embodiments, the second control unit 6 is signal-connected to the second sensor 8 to control the opening degree of the isolation device 3 in the open state according to the detection result of the second sensor 8 .

[0076] In some examples, when the temperature detected by the second sensor 8 is higher, the second control unit 6 may correspondingly increase the degree of opening of the isolation device 3 in the open state. Increasing the degree of opening of the isolation device 3 means increasing the flow capacity of the isolation device 3. For example, the isolation device 3 may be provided with a variable flow area, and when the temperature of the cooling water increases by a preset temperature (e.g., 10°C, 20°C) or a preset proportion (e.g., 10%), the second control unit 6 increases the flow area of ​​the isolation device 3 by a preset proportion (e.g., 10%).

[0077] In other examples, the second sensor 8 may also be used to detect the temperature of the air inlet of the radiator 2 close to the power system 1. In this case, when the second sensor 8 detects that the temperature of the air inlet is abnormally increased (for example, the temperature increase rate exceeds a set threshold), the second control unit 6 may reduce the opening of the isolation device 3 to reduce the possible heat backflow effect.

[0078] In the disclosed embodiment, the first control unit 5 and the second control unit 6 can collaboratively control the actions of the air supply device 22 and the isolation device 3. For example, when the air supply speed of the air supply device 22 is increased, the opening degree of the isolation device 3 is increased to obtain a more stable heat dissipation flow field and improve the heat dissipation efficiency of the radiator 2.

[0079] In some embodiments, reference Figure 4 As shown, the two-way vehicle further includes a main control unit 10. The main control unit 10 is configured to collect operating status information of each system in the vehicle. The first control unit 5 and the second control unit 6 are connected to the main control unit 10 by signal. The main control unit 10 sends instructions to the first control unit 5 and the second control unit 6 based on the received vehicle operating status information, such as the vehicle driving direction detected by the first sensor 7 and the cooling water temperature detected by the second sensor 8, and then controls the actions of the air supply device 22 and the isolation device 3 through the first control unit 5 and the second control unit 6.

[0080] In some embodiments of the present disclosure, the air supply device 22 includes an electronic fan connected to the first control unit 5 by signal. The first control unit 5 is configured to control the electronic fan to rotate in a first direction to drive the airflow from the side of the heat dissipation core 21 away from the power system 1 to the side of the heat dissipation core 21 close to the power system 1. Alternatively, the first control unit 5 is configured to control the electronic fan to rotate in a second direction to drive the airflow from the side of the heat dissipation core 21 close to the power system 1 to the side of the heat dissipation core 21 away from the power system 1, and the second direction is opposite to the first direction.

[0081] The electronic fan is driven by an electric motor. Compared with a traditional mechanical fan, the electronic fan is easier to control electrically and has high responsiveness, which helps to improve the response speed of the air supply device to the vehicle's reversing driving and improve the heat dissipation efficiency of the radiator 2.

[0082] As an example, the electronic fan may be an axial flow fan.

[0083] refer to Figure 1 As shown, when the axial flow fan rotates in a first direction (for example, clockwise when viewed from the direction of the power system 1 toward the fan), the fan drives the airflow from the side of the heat dissipation core 21 away from the power system 1 to the side of the heat dissipation core 21 close to the power system 1, thereby achieving the effect of sucking air into the power compartment 4.

[0084] refer to Figure 2 As shown, when the axial fan rotates in the second direction (for example, counterclockwise when viewed from the direction of the power system 1 toward the fan), the fan drives the airflow from the side of the heat dissipation core 21 close to the power system 1 to the side of the heat dissipation core 21 away from the power system 1, thereby achieving the effect of blowing air out of the power compartment 4.

[0085] In the embodiment of the present disclosure, there are many options for the specific form of the isolation device 3, as long as it has a structure that can adjust the flow area or flow capacity. For example, a rotatable blade can be set in the isolation device 3, or a slidable baffle structure can be set in the isolation device 3.

[0086] refer to Figure 5 As shown, in some embodiments, the isolation device 3 includes a mounting frame 31 and a blade 32 rotatably mounted on the mounting frame 31. When the isolation device 3 is in a closed state, the blade 32 is closed relative to the mounting frame 31 to close the opening plane of the mounting frame 31. When the isolation device 3 is in an open state, the blade 32 is opened relative to the mounting frame 31 and forms a preset angle greater than 0 degrees with the opening plane.

[0087] As an example, the mounting frame 31 may be connected between the frame 41 and the hood 42 to achieve fixed installation of the isolation device 3 relative to the power compartment 4 .

[0088] like Figure 5 As shown, when the blade 32 is open relative to the mounting frame 31, the preset angle formed between it and the opening plane is shown as α in the figure. The dotted line in the figure is the opening plane of the mounting frame 31. The larger the angle α, the more air flow can flow through the opening plane. Correspondingly, when the blade 32 is closed relative to the mounting frame 31, the angle between it and the opening plane is 0 degrees.

[0089] In a specific example, the power system 1 includes an engine, and the radiator 2 includes a water-cooled core for cooling the engine cylinder. Assuming that the angle α of the blade 32 of the isolation device 3 is 0 degrees when it is fully closed relative to the mounting frame 31, and the angle α of the blade 32 is 90 degrees when it is fully opened relative to the mounting frame 31, several intermediate angles can be set between the fully closed state and the fully open state of the blade 32, such as 30 degrees, 45 degrees and 60 degrees.

[0090] The angle can be switched according to the change of the cooling water temperature.

[0091] For example, when the engine's cooling water temperature is lower than 82°C, the control blade 32 is rotated to an angle α of 30 degrees; when the engine's cooling water temperature is in the range of 82°C to 87°C, the control blade 32 is rotated to an angle α of 45 degrees; when the engine's cooling water temperature is in the range of 87°C to 92°C, the control blade 32 is rotated to an angle α of 60 degrees; when the engine's cooling water temperature is higher than 92°C, the control blade 32 is rotated to an angle α of 90 degrees, which is the fully open angle.

[0092] In some other examples, if the power system 1 includes other heat-generating components besides the engine, the size of the angle α can be set according to the actual operating temperature requirements of the heat-generating components with reference to the control method described in the above example.

[0093] refer to Figure 5 As shown, in some embodiments, the isolation device 3 also includes a driving device and a rotating shaft 33, the blades 32 are fixedly mounted on the rotating shaft 33, the rotating shaft 33 is rotatably mounted on the mounting frame 31, and the driving device is configured to drive the rotating shaft 33 to rotate to drive the blades 32 to open or close relative to the mounting frame 31.

[0094] In some embodiments, the second control unit 6 is connected to the driving device signal to control the output angle of the driving device according to the detection result of the second sensor 8, thereby controlling the rotation angle of the rotating shaft 33 and further controlling the size of the preset angle.

[0095] In some embodiments, reference Figure 6 As shown, the driving device may include an electric motor 34 and a reducer 35, wherein the electric motor 34 is configured to drive the rotating shaft 33 to rotate, and the reducer 35 is connected between the electric motor 34 and the rotating shaft 33. The second control unit 6 is connected to the electric motor 34 by signal to control the output rotation angle of the electric motor 34.

[0096] Furthermore, different gear outputs of the drive device can be realized by adjusting the matching relationship between the electric motor 34 and the reducer 35, and different preset angles can be obtained in each gear. For example, the outputs of the first, second, third and fourth gears can be set, and the corresponding angles α can be 30 degrees, 45 degrees, 60 degrees and 90 degrees respectively. Here, the higher the temperature detected by the second sensor 8, the larger the gear output of the drive device can be set.

Although the present disclosure has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that without departing from the principles of the present disclosure, the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, and these modifications and equivalent replacements should be included in the scope of the technical solution for protection of the present disclosure.
