[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0045] In the related art, electric working machinery usually only focuses on power performance and does not make special optimizations in terms of body size. Specifically, due to the large volumes of key components such as motors, power batteries, and hydraulic systems, these components often occupy a large amount of space, making the overall length and width dimensions of the working machinery relatively large.

[0046] For example, in the related art, the hydraulic system includes an oil tank and an oil pump, and the oil pump is drivingly connected to the motor. If the oil tank and the motor are distributed along the front-back direction of the working machinery, it will result in a relatively large size of the working machinery in the front-back direction. Similarly, if the oil tank and the motor are distributed along the left-right direction of the working machinery, it will result in a relatively large size of the working machinery in the left-right direction.

[0047] To solve or improve the problem of the relatively large overall length and width dimensions of the working machinery in the related art, an upper mounting arrangement structure and a working machinery are provided in the embodiments of the present utility model.

[0048] The following will describe the upper mounting arrangement structure provided in the embodiments of the present utility model in conjunction with Figures 1 to 5 , the embodiments of the present utility model.

[0049] Specifically, the upper mounting arrangement structure includes a slewing platform 1, a cab 2, an oil tank 3, a motor 4, an oil pump 5, and a power battery 6.

[0050] Among them, the slewing platform 1 is used to be mounted on the chassis or base of the working machinery.

[0051] The cab 2 is arranged on the slewing platform 1. For example, the cab 2 can be connected to the slewing platform 1 by welding or fastener connection.

[0052] The oil tank 3 is arranged on the slewing platform 1, and the oil tank 3 is located on the left or right side of the cab 2. The oil tank 3 is used to store hydraulic oil. Referring to Figure 1 shown, the W direction in the figure faces the left side of the cab 2, that is, Figure 1 the oil tank 3 in the figure is arranged on the right side of the cab 2. Of course, the oil tank 3 can also be arranged on the left side of the cab 2.

[0053] The motor 4 and the oil pump 5 are drivingly connected, that is, the output shaft of the motor 4 is connected to the input shaft of the oil pump 5, so that the motor 4 can drive the oil pump 5 to operate. Both the motor 4 and the oil pump 5 are arranged on the slewing platform 1, and the motor 4 and the oil pump 5 are arranged below the fuel tank 3. Refer to Figure 1 As shown, the H direction in the figure is the height direction of the cab 2, that is, in the height direction of the cab 2, the motor 4 and the oil pump 5 are arranged below the fuel tank 3. Optionally, the inlet of the oil pump 5 is connected to the fuel tank 3 for pumping oil from the fuel tank 3.

[0054] The power battery 6 is arranged on the slewing platform 1, and the power battery 6 is located behind the cab 2. Refer to Figure 1 As shown, the L direction in the figure faces the front of the cab 2, so the rear of the cab 2 is opposite to the L direction. Optionally, the power battery 6 is electrically connected to the motor 4 and is used to supply power to the motor 4. Optionally, the power battery 6 can be connected to the slewing platform 1 through fasteners.

[0055] In this embodiment, the power battery 6 is arranged behind the cab 2, which can make full use of the space behind the cab 2 and reduce the size of the working machine in the left-right direction of the cab 2.

[0056] By arranging the motor 4 and the oil pump 5 below the fuel tank 3, the space of the slewing platform 1 in the height direction of the cab 2 can be fully utilized. Compared with the form where the motor 4 and the fuel tank 3 are distributed in the horizontal direction, the size of the upper-mounted layout structure in the horizontal direction can be effectively reduced, thus solving or improving the problem of the relatively large overall length and width of the working machine.

[0057] In addition, since the vibration frequency of the motor 4 and the oil pump 5 is relatively high during operation, by arranging the motor 4 and the oil pump 5 below the fuel tank 3, the motor 4 and the oil pump 5 are closer to the slewing platform, so that the self-weight and structure of the slewing platform can be used to better absorb and disperse the vibration energy, reduce the impact of vibration on the entire working machine, and improve the stability of the working machine.

[0058] In addition, during the oil suction process of the oil pump 5, the oil pump 5 can suck oil from the bottom of the fuel tank 3, reducing the possibility of inhaling air and generating bubbles, which helps to maintain the stability and efficiency of the hydraulic system. And the oil in the fuel tank 3 naturally flows to the oil pump 5 under the action of gravity, reducing the oil suction difficulty and energy consumption of the oil pump 5.

[0059] Finally, by arranging the oil pump 5 below the fuel tank 3, the length of the oil pipe can be reduced, thereby reducing the laying difficulty of the oil pipe, avoiding problems such as interference or entanglement of the oil pipe, and saving the cost of the oil pipe.

[0060] It can be understood that the upper-mounted layout structure provided by the present utility model is more compact in the horizontal direction, so it is more suitable for working machines such as mini excavators.

[0061] Reference Figure 2 As shown, in some embodiments provided by the present utility model, an avoidance space 201 is provided at the lower end of the rear part of the cab 2, and at least part of the power battery 6 is placed in the avoidance space 201. In this embodiment, by providing the avoidance space 201 at the rear part of the cab 2, at least part of the power battery 6 can be placed in the avoidance space 201, that is, the power battery 6 can be arranged overlapping with the cab 2, thereby shortening the size of the working machine in the front-rear direction of the cab 2.

[0062] Reference Figure 1 As shown, in some embodiments provided by the present utility model, the superstructure layout structure further includes a first support assembly 23.

[0063] Among them, the first support assembly 23 is arranged above the slewing platform 1, and there is a distance between the first support assembly 23 and the slewing platform 1. The fuel tank 3 can be connected to the surface of the first support assembly 23 facing away from the slewing platform 1 through fasteners. The motor 4 and the oil pump 5 are arranged between the first support assembly 23 and the slewing platform 1.

[0064] Optionally, the first support assembly 23 includes, but is not limited to, a support plate, and the support plate can be connected to the slewing platform 1 through a connecting plate or a connecting rod.

[0065] Optionally, the motor 4 or the oil pump 5 can be connected to the slewing platform 1 through a corresponding mounting bracket.

[0066] In some embodiments provided by the present utility model, the superstructure layout structure further includes a radiator assembly 7.

[0067] Among them, the radiator assembly 7 is arranged on the slewing platform 1. The radiator assembly 7 and the fuel tank 3 are on the same side of the cab 2, and the radiator assembly 7 and the fuel tank 3 are distributed along the front-rear direction of the cab 2. For example, the radiator assembly 7 is connected to the fuel tank 3 through a liquid cooling pipeline and is used to cool the fuel tank 3.

[0068] In this embodiment, the radiator assembly 7 and the fuel tank 3 are on the same side of the cab 2, and the radiator assembly 7 and the fuel tank 3 are distributed along the front-rear direction of the cab 2, so that the radiator assembly 7 can be closer to the fuel tank 3. On the one hand, this can reduce the length of the liquid cooling pipeline between the fuel tank 3 and the radiator assembly 7, thereby reducing the difficulty of pipeline laying, avoiding pipeline winding interference, and improving the cooling efficiency of the radiator assembly 7 for the fuel tank 3. On the other hand, it can make it easier for the operator to access the radiator assembly 7 and the fuel tank 3, so as to facilitate unified cleaning, inspection, replacement and other work.

[0069] Optionally, the radiator assembly 7 includes a cooler and a fan. For example, the fan is disposed on the first side of the cooler away from the cab 2. The rotation of the fan generates a directional air flow, which passes through the fins or tube bundles of the cooler, taking away the heat therein.

[0070] Optionally, the radiator assembly 7 is arranged adjacent to the fuel tank 3 to improve the compactness of the superstructure layout.

[0071] Optionally, referring to Figure 1 As shown, the radiator assembly 7 is disposed behind the fuel tank 3. Of course, the radiator assembly 7 can also be disposed in front of the fuel tank 3.

[0072] Optionally, the radiator assembly 7 can be connected to the slewing platform 1 through a support plate. The support plate is disposed above the slewing platform 1 and has a spacing from the slewing platform 1. The radiator assembly 7 can be connected to the support plate through fasteners. For example, the support plate can be connected to the slewing platform 1 through a connecting plate or a connecting rod.

[0073] Furthermore, the radiator assembly 7 and the fuel tank 3 can be integrated on the same support plate, or can be respectively disposed on corresponding support plates.

[0074] In some embodiments provided by the present utility model, the superstructure layout further includes a first expansion tank 8, and the first expansion tank 8 is disposed above the radiator assembly 7. For example, the first expansion tank 8 is connected to the liquid cooling pipeline of the fuel tank 3.

[0075] In this embodiment, by disposing the first expansion tank 8 above the radiator assembly 7, the requirement that the installation position of the expansion tank needs to be as high as possible can be met, so as to ensure that it can effectively play the roles of volume compensation and exhaust.

[0076] Optionally, the first expansion tank 8 can be connected to the top of the radiator assembly 7 through fasteners.

[0077] Referring to Figure 1 、 Figure 4 and Figure 5 As shown, in some embodiments provided by the present utility model, the top of the radiator assembly 7 is provided with a stepped structure. In order to adapt to the top shape of the radiator assembly 7 and make the volume of the first expansion tank 8 meet the use requirements, the first expansion tank 8 includes a first cavity portion 801 and a second cavity portion 802 that are interconnected.

[0078] Wherein, the first cavity portion 801 and the second cavity portion 802 are arranged at an angle. For example, the first cavity portion 801 and the second cavity portion 802 are perpendicular. The first cavity portion 801 can be placed on the first surface of the stepped structure, and the second cavity portion 802 can be placed on the second surface of the stepped structure. And along the height direction of the cab 2, the first surface exceeds the second surface.

[0079] In some embodiments provided by the present utility model, the upper mounting arrangement structure further includes a storage battery 9. The storage battery 9 is disposed on the slewing platform 1, and the storage battery 9 is located below the radiator assembly 7, that is, the storage battery 9 is arranged between the support plate of the radiator assembly 7 and the slewing platform 1.

[0080] Optionally, the storage battery 9 can be connected to the slewing platform 1 through fasteners. It should be noted that the storage battery 9 can be used to start the electronic system of the working machine or supply power to electronic components such as a lighting system, an audio system, an instrument panel, windshield wipers, and window lifters.

[0081] In this embodiment, by arranging the storage battery 9 below the radiator assembly 7, the space below the radiator assembly 7 can be fully utilized, the compactness of the upper mounting arrangement structure can be improved, and the occupied area of the entire device in the horizontal direction can be reduced. In addition, the storage battery 9 has a large weight, and arranging it below the radiator assembly 7 helps to lower the center of gravity of the upper mounting arrangement structure and improve the stability of the upper mounting arrangement structure.

[0082] In some embodiments provided by the present utility model, the upper mounting arrangement structure further includes a condenser 10. The condenser 10 is disposed on one side of the radiator assembly 7 close to the cab 2. The condenser 10 is used to condense the refrigerant into a liquid state and release heat.

[0083] In this embodiment, by arranging the condenser 10 on one side of the radiator assembly 7 close to the cab 2, the condenser 10 can share a fan with the cooler of the radiator assembly 7, thereby saving space and cost.

[0084] Reference Figure 3 As shown, in some embodiments provided by the present utility model, the upper mounting arrangement structure further includes an air-conditioning assembly 11. The air-conditioning assembly 11 is disposed inside the cab 2. For example, the air-conditioning assembly 11 is connected to the condenser 10, and under the action of a compressor 12, the refrigerant circulates between the air-conditioning assembly 11 and the condenser 10 and transfers heat, achieving the effect of adjusting the temperature of the cab 2.

[0085] In this embodiment, by arranging the air-conditioning assembly 11 inside the cab 2, the temperature of the cab 2 can be adjusted through the air-conditioning assembly 11, so that the driver can work in an environment with a suitable temperature.

[0086] Reference Figure 1 As shown, the upper mounting arrangement structure further includes a compressor 12.

[0087] Among them, the compressor 12 is arranged on the slewing platform 1, and the compressor 12 and the storage battery 9 are distributed along the front-back direction of the cab 2. For example, the compressor 12 is connected to the air-conditioning assembly 11 and the condenser 10, and enables the refrigerant to flow between the air-conditioning assembly 11 and the condenser 10 and transfer heat, achieving the effect of adjusting the temperature of the cab 2.

[0088] In this embodiment, the compressor 12 and the storage battery 9 are distributed along the front-back direction of the cab 2, so that the operator can more conveniently access the compressor 12, facilitating the repair, maintenance and refrigerant filling of the compressor 12.

[0089] Optionally, referring to Figure 1 As shown, the compressor 12 is arranged behind the storage battery 9. Of course, the compressor 12 can also be arranged in front of the storage battery 9.

[0090] Optionally, the compressor 12 is connected to the slewing platform 1 through a corresponding bracket.

[0091] Optionally, the compressor 12 is arranged below the radiator assembly 7 and the condenser 10, so that the distance between the compressor 12 and the condenser 10 is closer, thereby being able to shorten the pipeline length between the compressor 12 and the condenser 10, further reducing the pipeline laying difficulty, avoiding pipeline entanglement or interference and reducing the pipeline cost.

Among them, the first battery pack 601 is arranged on the slewing platform 1, and the second battery pack 602 is arranged above the first battery pack 601.

[0093] In this embodiment, by vertically stacking the first battery pack 601 and the second battery pack 602, the space in the height direction of the slewing platform 1 can be more effectively utilized, reducing the planar area occupied by the power battery 6, contributing to the compact design of the work machine and reducing its floor area.

[0094] Optionally, the superstructure layout structure further includes a second support assembly 24 and a third support assembly 25.

[0095] Among them, the second support assembly 24 is arranged above the slewing platform 1 and has a spacing from the slewing platform 1. For example, the second support assembly 24 is connected to the slewing platform 1.

[0096] The third support assembly 25 is arranged above the second support assembly 24 and has a spacing from the second support assembly 24. For example, the third support assembly 25 is connected to the second support assembly 24.

[0097] Among them, the first battery pack 601 is disposed between the slewing platform 1 and the second support assembly 24. For example, the first battery pack 601 is connected to the slewing platform 1. The second battery pack 602 is disposed between the second support assembly 24 and the third support assembly 25.

Through the second access opening, the second battery pack 602 can be installed between the second support assembly 24 and the third support assembly 25, or the second battery pack 602 can be withdrawn from between the second support assembly 24 and the third support assembly 25 for maintenance and replacement.

[0101] Optionally, at least one of the second support assembly 24 and the third support assembly 25 includes a support plate. For example, the support plate of the second support assembly 24 can be connected to the slewing platform 1 through a connecting plate or a connecting rod, and the support plate of the third support assembly 25 can be connected to the second support assembly 24 through a connecting plate or a connecting rod.

The distribution box 13 is disposed above the power battery 6. Optionally, the distribution box 13 is also referred to as a high-voltage power distribution box and is electrically connected to the power battery 6, and can implement functions such as power distribution management and safety protection. For example, the distribution box 13 can be installed on the third support assembly 25.

[0103] In this embodiment, arranging the distribution box 13 above the power battery 6 can significantly shorten the electrical path, that is, shorten the wire length between the power battery 6 and the distribution box 13, thereby reducing the resistance loss, improving the efficiency of power transmission, and reducing costs and weight. In addition, when it is necessary to inspect or replace the battery or the distribution box 13, the relevant components can be accessed more quickly, reducing the workload of disassembling other components.

[0104] In some embodiments provided by the present utility model, the upper-mounted layout structure further includes an all-in-one controller 14, and the all-in-one controller 14 is arranged above the power battery 6. For example, the all-in-one controller 14 is electrically connected to at least the motor 4 and can at least control the motor 4.

[0110] In addition, the battery management component 15 usually generates a certain amount of heat. By placing it above the distribution box 13 or the all-in-one controller 14, the relatively open space above can be used for heat dissipation to avoid heat accumulation affecting system performance.

[0111] In some embodiments provided by the present invention, the upper mounting arrangement structure further includes an electric heater 16. For example, the electric heater 16 is configured as a WPTC heater.

[0112] The electric heater 16 is disposed on the rotary platform 1, and the electric heater 16 is located on the side of the power battery 6 away from the cab 2. For example, the electric heater 16 is connected to the liquid cooling pipeline of the power battery 6 and is used to heat the power battery 6. Optionally, the electric heater 16 is connected to the second support assembly 24.

[0113] In this embodiment, the electric heater 16 is provided to heat the power battery 6 so that the power battery 6 can work in a relatively low temperature environment. By arranging the electric heater 16 on the side of the power battery 6 away from the cab 2, the electric heater 16 is closer to the power battery 6, thereby reducing the length of the pipeline between the electric heater 16 and the power battery 6, reducing the difficulty of laying the pipeline, avoiding interference and entanglement of the pipeline, and reducing the weight and cost of the pipeline.

[0114] In some embodiments provided by the present invention, the upper mounting arrangement structure further includes an electronic water pump 17 .

[0115] The electronic water pump 17 is disposed on the rotary platform 1, and the electronic water pump 17 is located on the side of the power battery 6 away from the cab 2. For example, the electronic water pump 17 is connected to the liquid cooling pipeline of the power battery 6 and is used to drive the coolant circulation. Optionally, the electronic water pump 17 is connected to the second support assembly 24.

[0116] In this embodiment, the electronic water pump 17 is provided to drive the coolant circulation, thereby improving the cooling and heating effect of the coolant on the power battery 6. By arranging the electronic water pump 17 on the side of the power battery 6 away from the cab 2, the electronic water pump 17 is closer to the power battery 6, thereby reducing the length of the pipeline between the electronic water pump 17 and the power battery 6, reducing the difficulty of laying the pipeline, avoiding interference and entanglement of the pipeline, and reducing the weight and cost of the pipeline.

[0117] In some embodiments provided by the present invention, the upper mounting arrangement structure further includes a second expansion water tank 18 .

[0118] Among them, the second expansion tank 18 is arranged above the power battery 6. For example, the second expansion tank 18 is connected to the liquid cooling pipeline of the power battery 6, playing the role of volume compensation and exhaust. Optionally, the second expansion tank 18 is arranged above the battery management component.

[0119] In this embodiment, by arranging the second expansion tank 18 above the power battery 6, the requirement that the installation position of the expansion tank needs to be as high as possible can be met to ensure that it can effectively play the role of volume compensation and exhaust.

[0120] In some embodiments provided by the present utility model, the upper mounting layout structure further includes a heat exchanger 19. For example, the heat exchanger 19 can be arranged as a plate heat exchanger.

[0122] Optionally, the first heat exchange flow channel of the heat exchanger 19 is connected to the liquid cooling pipeline of the power battery 6, and the second heat exchange flow channel of the heat exchanger 19 is respectively connected to the compressor 12 and the condenser 10. That is, the coolant of the power battery 6 enters the heat exchanger 19 to release heat and cool down, and then enters the power battery 6 to absorb the heat of the power battery 6, so as to achieve the effect of cooling the power battery 6. The refrigerant in the second heat exchange flow channel of the heat exchanger 19 enters the condenser 10 under the action of the compressor 12 to release heat. For example, the heat exchanger 19 can share the compressor 12 and the condenser 10 with the air conditioning assembly 11.

[0123] In this embodiment, by arranging the heat exchanger 19, the power battery 6 can be cooled to avoid the temperature of the power battery 6 being too high. By arranging the heat exchanger 19 on the side of the power battery 6 away from the cab 2, the heat exchanger 19 is closer to the power battery 6, thereby reducing the pipeline length between the heat exchanger 19 and the power battery 6, reducing the pipeline laying difficulty, avoiding problems of pipeline interference and entanglement, and reducing the weight and cost of the pipeline.

[0124] Reference Figure 3 and Figure 4 As shown, in some embodiments provided by the present utility model, the upper mounting layout structure further includes a protective member 20.

[0125] Among them, the protective member 20 is connected to the slewing platform 1, and the protective member 20 is arranged on the side of the power battery 6 away from the cab 2.

[0126] In this embodiment, since the power battery 6 is arranged behind the cab 2, the power battery 6 is prone to being impacted. By providing the protective member 20, the power battery 6 can be protected, reducing the risk of the power battery 6 being impacted. In addition, the protective member 20 and the power battery 6 are jointly arranged behind the cab 2, which can play a role in counterweight and avoid the problem of overturning during the operation of the working machine.

[0128] Among them, the hydraulic valve group 21 is arranged on the slewing platform 1, and the hydraulic valve group 21 is located below the cab 2.

[0129] In this embodiment, by installing the hydraulic valve group 21 below the cab 2, the bottom space of the cab 2 can be effectively utilized, avoiding occupying the horizontal space of the slewing platform 1, making the horizontal direction of the slewing platform 1 more compact, helping to reduce the length and width dimensions of the working machine, and improving the flexibility of the working machine.

[0130] Optionally, the hydraulic valve group 21 is arranged below the side door of the cab 2. Placing the hydraulic valve group 21 below the side door of the cab 2 enables maintenance personnel to easily access these components without entering the interior of the cab 2 or moving a large number of components, thus simplifying the maintenance and repair process.

[0131] In some embodiments provided by the present utility model, the upper mounting arrangement structure further includes a slewing motor 22.

[0132] The slewing motor 22 is arranged on the slewing platform 1, and the slewing motor 22 is located below the cab 2. It can be understood that a gear is provided on the output shaft of the slewing motor 22, and the gear can be used to mesh with a gear ring on the base or chassis so that the slewing platform 1 can rotate relative to the base or chassis.

[0133] In this embodiment, by installing the slewing motor 22 below the cab 2, on the one hand, the space at the bottom of the cab 2 can be maximally utilized, making the overall design more compact, and on the other hand, the influence of external rainwater, dust, etc. on the slewing motor 22 can be reduced.

[0134] The present utility model embodiment also provides a working machine.

[0135] Specifically, the working machine includes the upper mounting arrangement structure as described above.

[0136] It should be noted that since the working machine includes the upper mounting arrangement structure, it also includes all the above advantages of the upper mounting arrangement structure, so it will not be elaborated here.

[0137] Optionally, the work machine includes, but is not limited to, an excavator, a loader, and a pile driver. Among them, the excavator may be a mini-excavator.
