[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] Hereinafter, with reference to the accompanying drawings, an energy recovery system 100 for a hydraulic mount according to an embodiment of the present invention will be described.

[0032] like Figure 1-Figure 5 As shown, the energy recovery system 100 for a hydraulic mount according to an embodiment of the present invention includes two sets of hydraulic mounts 1 and a generator assembly 3. The two sets of hydraulic mounts 1 are used to mount the powertrain 300 on the vehicle frame 200. The hydraulic chambers 14 of the two sets of hydraulic mounts 1 are connected via a hydraulic pipeline 2. The generator assembly 3 includes a hydraulic motor 31 and a generator 32. The hydraulic motor 31 is connected to the hydraulic pipeline 2 and is located between the two sets of hydraulic mounts 1. When liquid flows through the hydraulic pipeline 2, the hydraulic chambers 14 of the two sets of hydraulic mounts 1 drive the hydraulic motor 31 to generate power. When the hydraulic motor 31 generates power, it drives the generator 32 to generate electricity.

[0033] Therefore, when the powertrain 300 vibrates, a pressure difference is formed between the hydraulic chambers 14 of the two groups of hydraulic mounts 1, and the liquid can flow between the hydraulic chambers 14 of the two groups of hydraulic mounts 1 through the hydraulic pipeline 2. The flowing liquid can drive the hydraulic motor 31 to rotate, thereby driving the generator 32 to generate electricity, thereby realizing the recovery of the vibration energy of the powertrain 300.

[0034] For example, refer to Figure 1 and Figure 2 As shown, the energy recovery system 100 may be provided with two sets of hydraulic mounts 1, which are spaced apart and used to connect the powertrain 300 to the vehicle frame 200 (of course, it may also be the vehicle body) to fix the powertrain 300 under the vehicle frame 200. Figure 4 The hydraulic mount 1 is formed with a hydraulic cavity 14 in which liquid is stored. The hydraulic pipeline 2 can connect the hydraulic cavities 14 of the two groups of hydraulic mounts 1, so that the liquid in the hydraulic cavity 14 of one group of hydraulic mounts 1 can flow to the hydraulic cavity 14 of the other group of hydraulic mounts 1 through the hydraulic pipeline 2.

[0035] The energy recovery system 100 also includes a power generation assembly 3, which includes a hydraulic motor 31 and a generator 32. The hydraulic motor 31 is mounted on the hydraulic pipeline 2 and positioned between the two sets of hydraulic mounts 1. The input end of the hydraulic motor 31 is adapted to extend into the inner cavity of the hydraulic pipeline 2, and the hydraulic motor 31 is power-connected to the generator 32. Thus, when the hydraulic chamber 14 of one set of hydraulic mounts 1 flows through the hydraulic pipeline 2 to the hydraulic chamber 14 of the other set of hydraulic mounts 1, the liquid drives the input end of the hydraulic motor 31 to rotate, which in turn drives the generator 32 to generate electricity. This allows the recovery of vibration energy from the powertrain 300.

[0036] During the specific working process, when the power assembly 300 is running and vibrating, the two sides of the power assembly 300 will produce a certain inclination, and the strokes of the hydraulic mounts 1 on both sides of the power assembly 300 are different, so that a pressure difference is generated in the hydraulic chambers 14 of the two groups of hydraulic mounts 1. The liquid in the hydraulic chamber 14 with a higher pressure can flow to the hydraulic chamber 14 with a lower pressure through the hydraulic pipeline 2. The flowing liquid can drive the input end of the hydraulic motor 31 to rotate, thereby driving the generator 32 to work, thereby generating electricity.

[0037] According to the energy recovery system 100 of an embodiment of the present invention, the hydraulic chambers 14 of the two groups of hydraulic mounts 1 are connected through a hydraulic pipeline 2, and a hydraulic motor 31 is installed on the hydraulic pipeline 2. When the power assembly 300 vibrates, a pressure difference is formed between the hydraulic chambers 14 of the two groups of hydraulic mounts 1. Liquid can flow between the hydraulic chambers 14 of the two groups of hydraulic mounts 1 through the hydraulic pipeline 2. The flowing liquid can drive the hydraulic motor 31 to rotate, so as to drive the generator 32 to generate electricity, thereby realizing the recovery of the vibration energy of the power assembly 300, reducing the vibration transmitted to the outside of the power assembly 300, and reducing noise.

[0038] In some embodiments of the present invention, at least one of the two groups of hydraulic mounts 1 has multiple hydraulic mounts 1; multiple connecting branches 21 are provided at the end of the hydraulic pipeline 2, and the multiple connecting branches 21 are all connected to the hydraulic pipeline 2, and the hydraulic chambers 14 of the multiple hydraulic mounts 1 are respectively connected to the multiple connecting branches 21.

[0039] For example, refer to Figure 2 A plurality of hydraulic mounts 1 can be provided in one group, with the plurality of hydraulic mounts 1 spaced apart and arranged, and another group of hydraulic mounts 1 can be provided with one. The corresponding ends of the hydraulic pipeline 2 are provided with a plurality of connecting branches 21, and the plurality of connecting branches 21 are all connected to the hydraulic pipeline 2, and the plurality of connecting branches 21 are used to be connected one-to-one with the plurality of hydraulic mounts 1 in one group, so as to connect the plurality of hydraulic mounts 1 in the two groups.

[0040] For example, two groups of hydraulic mounts 1 can each be provided with multiple hydraulic mounts 1, with the multiple hydraulic mounts 1 in each group arranged at intervals. Multiple connecting branches 21 are provided at both ends of the hydraulic pipeline 2, and the multiple connecting branches 21 are all connected to the hydraulic pipeline 2. The multiple connecting branches 21 at each end are used to correspond one-to-one with the multiple hydraulic mounts 1 in one group, thereby connecting the multiple hydraulic mounts 1 in the two groups.

[0041] It can be understood that by setting up multiple hydraulic mounts 1, the installation stability of the powertrain 300 is improved, and by connecting multiple hydraulic mounts 1 through the hydraulic pipeline 2, it is easier to form a pressure difference at both ends of the hydraulic pipeline 2, which is beneficial to improving the power generation efficiency of the generator 32 and improving the vibration energy recovery efficiency of the powertrain 300.

[0042] In some embodiments of the present invention, at least one group of hydraulic mounts 1 is composed of two, and the end of the hydraulic pipeline 2 is provided with two connecting branches 21 to communicate with the hydraulic chambers 14 of the two hydraulic mounts 1 respectively, and the two connecting branches 21 are connected to the hydraulic pipeline 2 through a three-way valve 22. For example, referring to Figure 2 One set of hydraulic mounts 1 can be configured with two hydraulic mounts 1 spaced apart, while another set of hydraulic mounts 1 can be configured with one hydraulic mount 1. Two connecting branches 21 can be provided at corresponding ends of the hydraulic pipeline 2. One end of each connecting branch 21 communicates with the hydraulic pipeline 2 via a three-way valve 22. The two connecting branches 21 are used to correspond one-to-one with the two hydraulic mounts 1 in one set, thereby connecting the two hydraulic mounts 1 to the hydraulic pipeline 2. Simultaneously, the other end of the hydraulic pipeline 2 communicates with the hydraulic mount 1 in another set.

[0043] It can be understood that by setting the three-way valve 22, the three-way valve 22 can connect the hydraulic pipeline 2 with the connecting branch 21, thereby achieving stable connection of multiple hydraulic mounts 1, and making the disassembly and assembly process of the hydraulic pipeline 2 simple, which is conducive to reducing the maintenance difficulty of the operator.

[0044] In some embodiments of the present invention, one of the two sets of hydraulic mounts 1 is connected and supported on a first side of the powertrain 300, while the other set is connected and supported on a second side of the powertrain 300. It will be appreciated that by installing the two sets of hydraulic mounts 1 on either side of the powertrain 300, the installation stability of the powertrain 300 is improved. Furthermore, when the powertrain 300 vibrates, the larger the vibration amplitude on both sides of the powertrain 300, the larger the stroke difference between the two sets of hydraulic mounts 1. This results in a larger pressure difference between the two sets of hydraulic mounts 1, increasing the amplitude and frequency of the fluid flow in the hydraulic pipeline 2, and thereby improving the vibration energy recovery efficiency of the powertrain 300.

[0045] In some embodiments of the present invention, one of the first and second sides is the front side of the powertrain 300, and the other is the rear side of the powertrain 300. For example, one set of hydraulic mounts 1 can be installed on the front side of the powertrain 300, and the other set of hydraulic mounts 1 can be installed on the rear side of the powertrain 300. In this way, when the vehicle accelerates or decelerates, a large pressure differential can be formed between the hydraulic chambers 14 of the two sets of hydraulic mounts 1, allowing the fluid to drive the hydraulic motor 31 and the generator 32. This helps improve the efficiency of vibration energy recovery in the powertrain 300.

[0046] In some embodiments of the present invention, one of the first and second sides is the left side of the powertrain 300, and the other is the right side of the powertrain 300. For example, one set of hydraulic mounts 1 can be installed on the left side of the powertrain 300, and the other set of hydraulic mounts 1 can be installed on the right side of the powertrain 300. This creates a significant pressure differential between the hydraulic chambers 14 of the two sets of hydraulic mounts 1 when the vehicle turns left or right, allowing the fluid to drive the hydraulic motor 31, which in turn drives the generator 32. This improves the efficiency of vibration energy recovery within the powertrain 300.

[0047] In some embodiments of the present invention, Figure 1 As shown, the power generation component 3 further includes a battery 33, which is connected to the generator 32 and is used to store the electrical energy generated by the generator 32. Figure 1 The power generation assembly 3 includes a battery 33, which can be a single cell. The battery 33 is electrically connected to the generator 32. When the hydraulic motor 31 drives the generator 32 to generate electricity, the generator 32 charges the battery 33. The battery 33 stores the electricity generated by the generator 32 and can be used to power other components of the vehicle. This helps improve the practicality of the energy recovery system 100.

[0048] In some embodiments of the present invention, Figure 1 As shown, the generator 32 and the hydraulic motor 31 are integrated. Through the above arrangement, the generator 32 and the hydraulic motor 31 can be integrated and installed on the hydraulic pipeline 2, which is simple and convenient to install and takes up little space, thereby improving the reliability and practicality of the energy recovery system 100.

[0049] In some embodiments of the present invention, Figure 4 As shown, the hydraulic mount 1 includes an exoskeleton 11, an inner skeleton 12 and a rubber main spring 13. The inner skeleton 12 is installed in the exoskeleton 11 and connected to the exoskeleton 11 through the rubber main spring 13. One of the exoskeleton 11 and the inner skeleton 12 is used to be connected to the powertrain 300 and the other is used to be connected to the frame 200. The exoskeleton 11 and / or the inner skeleton 12 and the rubber main spring 13 define a hydraulic chamber 14.

[0050] For example, refer to Figure 3-Figure 5 The hydraulic mount 1 includes an exoskeleton 11, an endoskeleton 12, and a rubber main spring 13. The endoskeleton 12 is tubular, while the exoskeleton 11 is a large-diameter circular tube. The exoskeleton 11 is adapted to fit over the outer side of the endoskeleton 12, with the inner sidewall of the exoskeleton 11 spaced apart from the endoskeleton 12 to form an annular accommodation space. The rubber main spring 13 is mounted within the accommodation space, with the outer side of the rubber main spring 13 connected to the exoskeleton 11 and the inner side connected to the endoskeleton 12, thereby achieving a connection between the endoskeleton 12 and the exoskeleton 11.

[0051] Among them, Figure 2 As shown, the inner frame 12 can be connected to the powertrain 300, and the outer frame 11 can be connected to the vehicle frame 200; alternatively, the outer frame 11 can be connected to the powertrain 300, and the inner frame 12 can be connected to the vehicle frame 200. This allows the powertrain 300 to be mounted on the vehicle frame 200 via the hydraulic mount 1. Furthermore, a hydraulic chamber 14 can be defined between the outer frame 11 and the rubber main spring 13, or between the inner frame 12 and the rubber main spring 13. Alternatively, the outer frame 11, the inner frame 12, and the rubber main spring 13 can collectively define the hydraulic chamber 14. In this way, when the powertrain 300 vibrates, it can drive the outer frame 11 and the inner frame 12 to move relative to each other, causing changes in the hydraulic chamber 14 and thereby altering the pressure within the hydraulic chamber 14. For example, the volume at the lower end of the hydraulic chamber 14 decreases, increasing the pressure within the hydraulic chamber 14, thereby creating a pressure differential between the hydraulic chambers 14 of the two sets of hydraulic mounts 1. This facilitates the recovery of vibration energy of the powertrain 300 and improves the reliability of the energy recovery system 100 .

[0052] For example, refer to Figure 4-Figure 5 A plug-in hole 121 with open ends can be provided on the inner frame 12, a limiting groove 122 can be formed on the inner wall of the plug-in hole 121, and a latch can be formed on the power assembly 300, and a limiting block can be provided on the outer peripheral wall of the latch. By inserting the latch into the plug-in hole 121 and making the limiting block extend into the limiting groove 122, the power assembly 300 and the hydraulic mount 1 can be stably installed.

[0053] In some embodiments of the present invention, the rubber main spring 13 and the outer frame 11 define a hydraulic chamber 14, and the outer frame 11 is provided with a hydraulic hole 15, which is used to connect the hydraulic chamber 14 with the hydraulic pipeline 2. For example, referring to Figure 4 A hydraulic cavity 14 can be defined between the rubber main spring 13 and the outer frame 11, and a hydraulic hole 15 is provided at the lower end of the outer frame 11. The hydraulic hole 15 is radially extending from the outer frame 11 (i.e. Figure 4The hydraulic hole 15 is arranged to extend in the upper and lower directions as shown, the upper end of the hydraulic hole 15 is connected to the lower part of the hydraulic chamber 14, and the lower end of the hydraulic hole 15 is used to communicate with the hydraulic pipeline 2, so that the hydraulic chamber 14 can be connected to the hydraulic pipeline 2 through the hydraulic hole 15.

[0054] Through the above arrangement, the communication between the hydraulic chamber 14 and the hydraulic pipeline 2 is stable and reliable, which is beneficial to improving the stability of liquid flow, reducing the failure rate of the energy recovery system 100, and improving user satisfaction.

[0055] The present invention also provides a vehicle.

[0056] A vehicle according to an embodiment of the present invention is provided with an energy recovery system 100 for a hydraulic mount according to any of the above-described embodiments. The hydraulic chambers 14 of the two hydraulic mounts 1 are connected via a hydraulic line 2, and a hydraulic motor 31 is mounted on the hydraulic line 2. When the powertrain 300 vibrates, a pressure differential is formed between the hydraulic chambers 14 of the two hydraulic mounts 1. Liquid can flow between the hydraulic chambers 14 of the two hydraulic mounts 1 through the hydraulic line 2. The flowing liquid drives the hydraulic motor 31 to rotate, driving the generator 32 to generate electricity. This recovers the vibration energy of the powertrain 300, reduces vibration transmitted outward from the powertrain 300, reduces noise, and improves the overall performance of the vehicle.
