Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a shock-absorbing motor mover. Background Technology

[0002] Existing automotive shock absorber motors include a water system, an electrical system, and an air system (the magnetorheological fluid assembly integrated on the shock absorber motor has an air regulating chamber on top, and the air system is used to regulate the pressure of the gas in the air regulating chamber during operation). Because the water system, electrical system, and air system need to be sealed, the existing shock absorber motor has a relatively complex structure, resulting in a large motor size that occupies a lot of space when installed in a car. Utility Model Content

[0003] The technical problem to be solved by this utility model embodiment is to provide a shock-absorbing motor mover to reduce the size of the motor.

[0004] To address the aforementioned technical problems, this utility model provides a shock-absorbing motor actuator, comprising a main shaft and a coil assembly mounted on the main shaft. The main shaft is cylindrical, with a magnetorheological fluid assembly in the middle. The magnetorheological fluid assembly includes an air regulating chamber. A T-shaped end cap is provided at the top of the main shaft, and a venting rod is provided in the middle of the T-shaped end cap. The bottom of the venting rod is connected to the magnetorheological fluid assembly and is correspondingly connected to the air regulating chamber. A heat dissipation channel is provided inside the main shaft, and a water inlet connector and a water outlet connector are provided on the T-shaped end cap. The water inlet connector and the water outlet connector are respectively sealed and connected to the water inlet end and the water outlet end of the heat dissipation channel.

[0005] Furthermore, a wiring cavity is formed between the top of the T-shaped end cap in the middle of the spindle and the top of the magnetorheological fluid assembly. The T-shaped end cap is equipped with a power line fixing connector, and the spindle is equipped with three motor power lines. One end of each of the three motor power lines is connected to the UVW three phases of the coil assembly, and the other end is led out from the wiring cavity and connected to the power line fixing connector.

[0006] Furthermore, a segment is provided at the bottom of the wiring cavity in the middle of the main spindle, and the segment is connected to the top of the magnetorheological fluid assembly by bolts.

[0007] Furthermore, sealant is applied between the bolt and the split section.

[0008] Furthermore, a seal is provided between the top of the spindle and the T-shaped end cap.

[0009] Furthermore, a sealing groove is provided at the bottom of the T-shaped end cap.

[0010] The beneficial effects of this utility model are as follows: This utility model integrates the air circuit, water circuit and electrical circuit together, while also waterproofing them separately, thereby reducing the size of the motor mover and thus the size of the motor, which can effectively reduce the space occupation.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0022] Please refer to Figures 1-6The shock-absorbing motor actuator of this embodiment includes a main shaft 10 and a coil assembly 20 disposed on the main shaft 10. The main shaft 10 is cylindrical, and a magnetorheological fluid assembly 11 is disposed in the middle of the main shaft 10 (i.e., inside the cylindrical main shaft 10). The magnetorheological fluid assembly 11 includes an air regulating chamber 12. The magnetorheological fluid assembly 11 is common knowledge in the art and will not be described in detail here.

[0023] The top of the spindle 10 is provided with a T-shaped end cap 30 (the longitudinal section of the T-shaped end cap 30 along its center is T-shaped). A vent rod 31 passes through the middle of the T-shaped end cap 30. The vent rod 31 is hollow in the middle. The bottom of the vent rod 31 is connected to the magnetorheological fluid assembly 11 and is correspondingly connected to the air regulating chamber 12. The air regulating chamber 12 is connected to the outside of the motor through the vent rod 31. The spindle 10 is provided with a cooling water channel 13, which facilitates heat dissipation through water cooling and removes the heat generated by the coil assembly 20. The T-shaped end cap 30 is provided with a water inlet connector 32 and a water outlet connector 33, which are respectively sealed to the water inlet and water outlet of the cooling water channel 13.

[0024] In one implementation, a wiring cavity 14 is formed between the top of the T-shaped end cap 30 in the middle of the spindle 10 and the top of the magnetorheological fluid assembly 11. The T-shaped end cap 30 is provided with a power line fixing connector 34. Three motor power lines 15 are provided inside the spindle 10 (i.e., inside the main body of the cylindrical spindle 10). One end of each of the three motor power lines 15 is connected to the three phases (UVW) of the coil assembly 20; the other end of each line is led out from the wiring cavity 14 and connected to the power line fixing connector 34, forming a single line for external wiring.

[0025] In one embodiment, a dividing section 16 is provided at the bottom of the wiring cavity 14 in the middle of the spindle 10. The dividing section 16 is connected to the top of the magnetorheological fluid assembly 11 by multiple bolts 17. The dividing section 16 divides the middle space of the spindle 10 into two parts, namely, the upper part is the wiring cavity 14, and the lower part is used to install the magnetorheological fluid assembly 11. The sealed wiring cavity 14 is waterproof.

[0026] As one implementation, a sealant is provided between the bolt 17 and the dividing part 16 to further improve sealing and waterproofing.

[0027] As one implementation, a seal 35 is provided between the top of the spindle 10 and the T-shaped end cap 30 to further improve sealing and waterproofing. The seal 35 may be an O-ring or formed of sealant.

[0028] As one implementation, the bottom of the T-shaped end cap 30 is provided with a sealing groove 36. The sealing groove 36 improves the sealing performance of the wiring cavity 14.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
