The regions shown in the figures are schematic in nature, and their shapes do not represent the actual shapes of the regions of the device and do not limit the scope of the embodiments of the present application.

[0032] In one embodiment, see Figure 1 , this embodiment provides a power device 100. It can be understood that the power device 100 can provide power for new energy equipment. As an example, the new energy equipment may include a tunnel construction vehicle, etc. Further, the power device 100 provided in this embodiment can be installed on the new energy equipment to replace the engine of the new energy equipment in the related art.

As an example, the first direction may include the opposite direction of the gravity direction. It is understood that the energy storage module 120 may be arranged above the chassis cross beam 110. This embodiment does not limit the specific connection method between the energy storage module 120 and the chassis cross beam 110, nor does it limit the specific size and other parameters of the energy storage module 120.

[0035] Furthermore, the energy storage module 120 may be located in the middle of the chassis cross beam 110 . Of course, the energy storage module 120 may also be located at one end of the chassis cross beam 110 .

[0036] See also Figure 1 , the functional module 130 may be located on a side of the energy storage module 120 away from the chassis cross beam 110 in the first direction, and the functional module 130 may be used to control the energy storage module 120. As an example, the functional module 130 may be arranged above the energy storage module 120, in which case the functional module 130, the energy storage module 120 and the chassis cross beam 110 may be stacked. The functional module 130 may include a plurality of subunits, and the plurality of subunits may be stacked above the energy storage module 120. This embodiment does not limit the specific composition of the functional module 130.

[0037] In addition, the strength of the surface of the functional module 130 and the energy storage module 120 away from the chassis cross beam 110 can meet the safety requirements and can withstand certain loads and impacts. The surface of the functional module 130 and the energy storage module 120 away from the chassis cross beam 110 can also provide an easy-to-open mechanism, such as a hinge, a lock, etc., so as to meet the heat dissipation, maintenance and repair requirements of the power device 100.

[0038] The motor module 140 may be mechanically connected to the chassis cross beam 110 and electrically connected to the energy storage module 120, and the energy storage module 120 is used to drive the motor module 140. As an example, the motor module 140 may be located on a side of the energy storage module 120.

[0039] In this embodiment, first, the energy storage module 120 is arranged on the chassis cross beam 110, and the functional module 130 is arranged on the side of the energy storage module 120 away from the chassis cross beam 110, and the functional module 130 is close to the energy storage module 120 to ensure the normal operation and efficient use of the energy storage module 120. Secondly, in this embodiment, the power device 100 is processed modularly, so that the production of the power device 100 can be made more efficient and flexible, and modules of different configurations can be quickly assembled and customized to meet diverse market needs. At the same time, the modular power device 100 is also convenient for maintenance and upgrading, and the faulty module can be quickly replaced, which reduces time and cost, improves equipment reliability, and is easy to upgrade technology. Finally, the modular power device 100 can also reduce production costs, reuse modules to reduce the purchase of new parts, and the modules can be recycled when scrapped, reducing resource waste and pollution.

[0040] In one embodiment, see Figure 1 The chassis cross beam 110 extends along the second direction, and the motor module 140 is located at one end of the chassis cross beam 110 in the second direction. Specifically, the chassis cross beam 110 may include a first chassis cross beam 111 and a second chassis cross beam 112 arranged in parallel, and the motor module 140 includes a first motor 141 and a second motor 142, the first motor 141 is mechanically connected to the first chassis cross beam 111, and the second motor 142 is mechanically connected to the second chassis cross beam 112.

[0041] As an example, the first motor 141 may include a drive motor, and the second motor 142 may include a steering motor. The drive motor may be used to drive the new energy equipment to work, and the front and rear of the drive motor may be connected to a transmission shaft, etc. The steering motor may be used as a chassis steering brake. In addition, the second motor 142 may also be used as an emergency power source for the upper arm, etc.

[0042] Accordingly, see Figure 1 The functional module 130 may include a first motor controller 131 and a second motor controller 132. The first motor controller 131 may be electrically connected to the first motor 141, and the second motor controller 132 may be electrically connected to the second motor 142. The first motor controller 131 and the second motor controller 132 may be used to receive control instructions and respectively drive the first motor 141 and the second motor 142 to achieve mechanical motion.

[0043] At this time, the first motor controller 131 and the second motor controller 132 can be arranged near the first motor 141 and the second motor 142, so as to facilitate the connection and arrangement of the wiring harness. Specifically, the preset parameter value of the first motor 141 is greater than the preset parameter value of the second motor 142, and the preset parameters at least include the motor size. In addition, the preset parameters may also include power, etc.

[0044] In this embodiment, by providing a first motor 141 mechanically connected to the first chassis cross beam 111, and a second motor 142 mechanically connected to the second chassis cross beam 112, the function of the power device 100 is increased, so that the power device 100 can not only drive the new energy equipment to work, but also control the chassis steering and braking.

[0045] In addition, the present embodiment may further include other motors. As an example, the present embodiment may further include a third motor, a fourth motor, etc. The third motor and the fourth motor may be connected to different positions of the chassis cross beam 110 .

[0046] In one embodiment, see Figure 1 The functional module 130 includes a power distribution unit 133 (Power Distribution Unit, PDU), a high-voltage distribution box 134, a charger unit 135 (On-Board Charger, OBC) and a water cooling unit 136 and other unit components.

[0047] The power distribution unit 133 can be electrically connected to the energy storage module 120 as a control center of the high voltage system. The power distribution unit 133 can be used to control the working condition of the power device 100 and coordinate whether each unit is powered on. As an example, the power distribution unit 133 can be located above the first motor controller 131 and the second motor controller 132.

[0048] The high-voltage distribution box 134 can be electrically connected to the energy storage module 120. The high-voltage distribution box 134 can be used to control the energy storage module 120 and distribute the high voltage of the energy storage module 120. As an example, the high-voltage distribution box 134 can be located on a side of the power distribution unit 133 away from the motor module 140.

[0049] The charger unit 135 can be electrically connected to the energy storage module 120 and the high-voltage distribution box 134. In the first direction, the high-voltage distribution box 134 can be located on a side of the charger unit 135 away from the energy storage module 120. The charger unit 135 can provide charging support for the energy storage module 120 by converting industrial AC power to battery DC power. For example, the charger unit 135 may include multiple circuit components such as transformers and rectifier bridges.

[0050] As an example, the high voltage distribution box 134 and the charger unit 135 may be located on a side of the power distribution unit 133 away from the motor module 140 .

[0051] The water cooling unit 136 can be used to adjust the temperature of the energy storage module 120. The water cooling unit 136 can be responsible for the cooling function of the energy storage module 120 to ensure that the energy storage module 120 operates at a normal operating temperature. As an example, the charger unit 135 and the water cooling unit 136 can be arranged in parallel, and the high-voltage distribution box 134 can be located on the side of the charger unit 135 and the water cooling unit 136 away from the energy storage module 120.

[0052] In this embodiment, by centrally arranging the various units of the functional module 130 and oriented in different positions, the insertion of the wiring harness (high voltage, low voltage, water cooling) is facilitated, and the length of these wiring harnesses can be shortened, saving the preparation cost of the wiring harness. Secondly, in this embodiment, the original engine position in the tunnel equipment, etc. can be replaced by the arrangement of this power device 100 to realize the electrification of the tunnel equipment, etc. Then, in this embodiment, the water cooling unit 136 is close to the energy storage module 120, which makes the cooling circuit of the water cooling unit 136 shorter, thereby facilitating the improvement of cooling efficiency. At the same time, in this embodiment, the various units of the functional module 130 can be arranged above the energy storage module 120, which is close to the top cover of the energy storage module 120, and both sides of the energy storage module 120 can contact each unit, thereby facilitating daily maintenance. Specifically, the upper and lower layers of the layout between the power distribution unit 133, the charger unit 135 and the water cooling unit 136 are in line with the output and input directions of the high-voltage wiring harness, and the modular layout of the power system is realized.

[0053] Understandably, Figure 1 The layout of each unit of the functional module 130 shown in FIG. 1 is only for illustrative purposes. In an actual embodiment, the functional module 130 is not limited to the multiple units provided in this embodiment, and the layout between the various units is not limited to the layout provided in this application. In addition, Figure 1 The size ratio of each unit of the functional module 130 and the size ratio relationship between the energy storage module 120 are only for exemplary description.

As an example, the new energy device may include a tunnel construction vehicle, etc.

[0055] Furthermore, after installing the power device 100, the motor module 140 can be debugged to check whether it is running normally and without abnormal phenomena. Subsequently, the opening and closing function of the top cover of the energy storage module 120 and the gap between it and the motor module 140 can be tested to avoid friction or damage. Finally, safety testing can also be performed to ensure that the system meets the standards and ensure driving safety.

[0056] The new energy equipment provided in this embodiment, first, sets the energy storage module 120 on the chassis cross beam 110, and sets the functional module 130 on the side of the energy storage module 120 away from the chassis cross beam 110, and the functional module 130 is close to the energy storage module 120 to ensure the normal operation and efficient use of the energy storage module 120. Secondly, in this embodiment, the power device 100 is processed modularly, so that the production of the power device 100 can be made more efficient and flexible, and modules with different configurations can be quickly assembled and customized to meet diverse market needs. At the same time, the modular power device 100 is also easy to repair and upgrade, and the faulty module can be quickly replaced, which reduces time and cost, improves equipment reliability, and is easy to upgrade technology. Finally, the modular power device 100 can also reduce production costs, reuse modules to reduce the purchase of new parts, and the modules can be recycled when scrapped, reducing resource waste and pollution.
