In some embodiments, the air pressure at the first vent hole 101 and the air pressure at the second vent hole 102 are different, so that there is an air pressure difference between the first vent hole 101 and the second vent hole 102, for example, when the air pressure at the first vent hole 101 is greater than the air pressure at the second vent hole 102, air flows into the medium channel through the first vent hole 101 and exits the medium channel through the second vent hole 102, and at this time, the first vent hole 101 is in an air-in state and the second vent hole 102 is in an air-out state; when the air pressure at the first vent hole 101 is smaller than the air pressure at the second vent hole 102, the air flows into the medium passage through the second vent hole 102 and is discharged out of the medium passage through the first vent hole 101, and at this time, the first vent hole 101 is in an air-out state and the second vent hole 102 is in an air-in state.

As shown in connection with fig. 1 and 11, in some embodiments, the body 400 of the vehicle may be formed with a vent 401, and the first vent 101 communicates with the vent 401, and during travel of the vehicle, a high-speed air flow F1 is formed at the vent 401, and according to bernoulli's principle, the air pressure at the vent 401 is smaller than the air pressure at the first vent 101, and further, since the first vent 101 and the second vent 102 pass through the medium passage, and since the second vent 102 is located at an end of the medium passage away from the vent 401, the air pressure at the second vent 102 will also be smaller than the air pressure at the first vent 101.
Thus, during the running of the vehicle, the pressure difference between the gas pressure of the vent 401 and the gas pressure of the second vent hole 102 is utilized to enable the gas to flow through the inside of the electromagnetic actuator 100 along the medium channel through the second vent hole 102, and during the process of flowing through the inside of the electromagnetic actuator 100, the heat exchange is performed between the gas and the heat generated by the electromagnetic actuator 100, which can be understood as that the flowing gas brings out the heat inside the electromagnetic actuator 100, so that the effect of cooling the electromagnetic actuator 100 by using the gas flow is achieved.
Similarly, in some embodiments, the second vent hole 102 communicates with the vent 401 to allow gas to flow along the media path through the first vent hole 101 and inside the electromagnetic actuator 100 to achieve the effect of cooling the electromagnetic actuator 100 with a gas flow.
As shown in fig. 1 and 13, in some embodiments, taking the case that the first vent hole 101 is in communication with the vent hole 401 as an example, during the running of the vehicle, the gas of the high-speed airflow F1 is suitable to flow to the first vent hole 101 through the vent hole 401, and then the gas flows along the medium channel, so that the gas flows through the inside of the electromagnetic actuator 100, and during the process that the gas flows through the inside of the electromagnetic actuator 100, the heat exchange is performed between the gas and the heat generated by the electromagnetic actuator 100, which can also be understood as that the flowing gas brings out the heat inside the electromagnetic actuator 100, thereby realizing the effect of cooling the electromagnetic actuator 100 by using the airflow.
Similarly, in some embodiments, the second vent hole 102 communicates with the vent 401 such that gas flows through the second vent hole 102 along the media path flow path inside the electromagnetic actuator 100 to achieve the effect of cooling the electromagnetic actuator 100 with a gas flow.
In summary, according to the electromagnetic actuator 100 of the embodiment of the invention, the air flows through the interior of the electromagnetic actuator 100 by utilizing the flowing characteristic of the air, and the air exchanges heat with the heat generated by the electromagnetic actuator 100 to realize the cooling effect of the electromagnetic actuator 100.
In some embodiments of the present invention, as shown in fig. 1 to 8, the medium channels include a medium channel, a first medium channel 31, and a second medium channel 32, the first electromagnetic assembly 1 is formed with the first medium channel 31, the second electromagnetic assembly 2 is formed with the second medium channel 32, or the second electromagnetic assembly 2 is formed with the first medium channel 31 and the second medium channel 32, or the first electromagnetic assembly 1 is formed with the first medium channel 31 and the second medium channel 32.
The assembly space 20 is internally provided with a medium flow passage, the medium flow passage is communicated with the first medium passage 31 and the second medium passage 32, the open end of the first medium passage 31, which is far away from the medium flow passage, is configured as a first vent hole 101, the open end of the second medium passage 32, which is far away from the medium flow passage, is configured as a second vent hole 102, and in the process that gas flows through the electromagnetic actuator 100, the gas can flow along the first medium passage 31, the medium flow passage and the second medium passage 32 in sequence, or alternatively, the gas can flow along the second medium passage 32, the medium flow passage and the first medium passage 31 in sequence, so that the effect of cooling the electromagnetic actuator 100 by utilizing the air flow is realized.
In some embodiments, as shown in connection with fig. 1-13, wherein the first electromagnetic assembly 1 is adapted to be coupled to a body 400 of a vehicle, as shown in fig. 1-6, the second electromagnetic assembly 2 is adapted to be coupled to a wheel end assembly of a vehicle, and wherein the second electromagnetic assembly 2 is adapted to be coupled to a body 400 of a vehicle, as shown in fig. 7 and 8, and the first electromagnetic assembly 1 is adapted to be coupled to a wheel end assembly of a vehicle.
When the electromagnetic actuator 100 works, electromagnetic induction can be generated between the first electromagnetic assembly 1 and the second electromagnetic assembly 2, so that the first electromagnetic assembly 1 and the second electromagnetic assembly 2 can relatively move along the axial direction of the electromagnetic actuator 100, namely, the electromagnetic actuator 100 can stretch and retract. During running of the vehicle, when the road applies a force to the wheel end assembly of the vehicle, the wheel end assembly of the vehicle can move relative to the vehicle body 400, and since the electromagnetic actuator 100 is connected between the vehicle body 400 and the wheel end assembly, the first electromagnetic component 1 and the second electromagnetic component 2 can relatively move along the axial direction of the electromagnetic actuator 100 by controlling, so that the electromagnetic actuator 100 can absorb the force applied by the road to the wheel end assembly of the vehicle, thereby reducing the force transmitted from the wheel end assembly of the vehicle to the vehicle body 400 of the vehicle, and further facilitating the improvement of the driving feeling of the vehicle. The axial direction of the electromagnetic actuator 100 is the Z direction shown in the drawings.
In some embodiments, as shown in fig. 11 and 12, and in conjunction with fig. 1-8, the vehicle body 400 is formed with a vent 401, and the first medium channel 31 is in communication with the vent 401 (i.e., the first vent 101 is in communication with the vent 401), during the running of the vehicle, a high-speed air flow F1 is formed at the vent 401, and according to bernoulli's principle, the air pressure at the vent 401 is smaller than the air pressure in the first medium channel 31, and further, because the first medium channel 31 and the second medium channel 32 pass through the medium channel, and the second medium channel 32 is located at the end of the medium channel away from the vent 401, the air pressure in the second medium channel 32 is also smaller than the air pressure in the first medium channel 31.
Thus, during the running of the vehicle, the pressure difference between the gas pressure of the vent 401 and the gas pressure of the second medium passage 32 is utilized to enable the gas to flow into the electromagnetic actuator 100 through the second medium passage 32, and the gas flows along the medium flow passage and the first medium passage 31 in sequence and then is discharged out of the electromagnetic actuator 100, and then the gas discharged from the electromagnetic actuator 100 is discharged out of the vehicle through the vent 401, and during the process of the gas flowing through the inside of the electromagnetic actuator 100, the heat exchange is performed between the gas and the heat generated by the electromagnetic actuator 100, thereby realizing the effect of cooling the electromagnetic actuator 100 by the gas flow.
In some embodiments, as shown in fig. 1 and 13, during the running of the vehicle, the gas of the high-speed airflow F1 is suitable for flowing into the first medium channel 31 through the ventilation opening 401, then flows into the electromagnetic actuator 100 through the first medium channel 31, flows along the medium flow channel and the second medium channel 32 in sequence, and then is discharged out of the electromagnetic actuator 100, and during the process of flowing through the inside of the electromagnetic actuator 100, the gas exchanges heat with the heat generated by the electromagnetic actuator 100, so that the effect of cooling the electromagnetic actuator 100 by using the airflow is achieved.
It should be noted that, in the radial direction of the electromagnetic actuator 100, the outer peripheral wall of the structure in which the first electromagnetic assembly 1 is located in the installation space 20 is spaced apart from the second electromagnetic assembly 2, so that a gap is formed between the first electromagnetic assembly 1 and the second electromagnetic assembly 2 in the installation space 20, ensuring that the first electromagnetic assembly 1 and the second electromagnetic assembly 2 move relatively in the axial direction of the electromagnetic actuator 100, and that gas can pass through the installation space 20 to flow between the first medium passage 31 and the second medium passage 32, and that the radial direction of the electromagnetic actuator 100 is perpendicular to the axial direction of the electromagnetic actuator 100.
In summary, according to the electromagnetic actuator 100 of the embodiment of the invention, the air flows through the interior of the electromagnetic actuator 100 by utilizing the flowing characteristic of the air, and the air exchanges heat with the heat generated by the electromagnetic actuator 100 to realize the cooling effect of the electromagnetic actuator 100.
In addition, it should be noted that in some embodiments, the faster the running speed of the vehicle is, the faster the flow rate of the gas flowing through the electromagnetic actuator 100 may be, so that the gas may rapidly dissipate heat of the electromagnetic actuator 100, and the better the heat dissipation effect of the electromagnetic actuator 100 is, so according to the electromagnetic actuator 100 of the embodiment of the present invention, the flow characteristic of the gas is utilized, so that the electromagnetic actuator 100 may meet the heat dissipation requirements of the vehicle at different running speeds, and the use reliability of the electromagnetic actuator 100 is ensured, thereby being beneficial to improving the driving feeling of the vehicle.
For example, during the high-speed running of the vehicle, the first electromagnetic assembly 1 and the second electromagnetic assembly 2 are affected by the wheel end assembly of the vehicle by the road, and compared with the vehicle in the low-speed running state, the frequency of the relative motion of the first electromagnetic assembly 1 and the second electromagnetic assembly 2 along the axial direction of the electromagnetic actuator 100 is higher, so that the heat generated by the electromagnetic actuator 100 is also larger during the high-speed running of the vehicle, and the speed of the gas flowing through the electromagnetic actuator 100 is increased by utilizing the flow characteristic of the gas, so that the heat dissipation capability of the electromagnetic actuator 100 is improved, and the working temperature of the electromagnetic actuator 100 can be maintained in a proper temperature range under the high-speed running state of the vehicle, so that the electromagnetic actuator 100 can meet the heat dissipation requirements of the vehicle at different running speeds, the use reliability of the electromagnetic actuator 100 is ensured, and the driving feel of the vehicle is further improved.
