Detailed Implementation

[0045] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0046] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" generally refer to "inner" and "outer" relative to the contour of the corresponding component itself. Terms such as "first" and "second" are used to distinguish one element from another and do not imply sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0047] Based on the specific embodiments provided in this disclosure, refer to Figures 1 to 5 As shown, a housing assembly for an electric motor is provided, the housing assembly including a housing 2 and a cover 5, the housing 2 having an installation space and an opening 22 communicating with the installation space, and the cover 5 covering the opening 22 and detachably connected to the housing 2.

[0048] Through the above technical solution, in the housing assembly for motor provided in this disclosure, the housing assembly includes a housing 2 and a cover 5. The housing 2 forms an installation space and has an opening 22 communicating with the installation space. The cover 5 is used to cover the opening 22 and is detachably connected to the housing 2. In this way, when the motor needs to be assembled, other components of the motor (such as magnetic components 3) only need to be installed in the installation space through the opening 22 provided in the housing 2, and then the cover 5 is fixed to the housing 2, so as to facilitate the assembly of the motor.

[0049] In the housing assembly for an electric motor provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2As shown, the housing assembly may include a positioning structure disposed between the housing 2 and the housing cover 5. In this way, when it is necessary to fix the housing cover 5 to the housing 2, the positioning structure disposed between the housing 2 and the housing cover 5 allows the operator to quickly find the installation position of the housing cover 5, thereby improving the assembly efficiency of the motor. At the same time, it can also ensure that the fit clearance between the housing cover 5 and the housing 2 meets the design requirements, so as to effectively avoid the scrapping of parts due to operational problems during the assembly process. In addition, the positioning structure can also ensure that the housing cover 5 is kept in the installation position, avoiding displacement or misalignment during long-term use.

[0050] In the housing assembly for an electric motor provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2 As shown, the positioning structure may include a first positioning structure and a second positioning structure. The first positioning structure can be used to position the cover 5 on the housing 2 in the circumferential direction of the housing 2, and the second positioning structure can be used to position the cover 5 on the housing 2 in the radial direction of the housing 2. In this way, the positioning of the cover 5 on the housing 2 can be achieved in multiple directions.

[0051] The first positioning structure can be constructed in any suitable form to achieve the purpose of positioning the cover 5 on the housing 2 in the circumferential direction of the housing 2, and this disclosure does not impose any specific restrictions on it.

[0052] As an exemplary embodiment, reference is made to Figure 2 As shown, the first positioning structure may include a first positioning hole 23, a second positioning hole 51, and a positioning pin. The housing 2 may be provided with at least one first positioning hole 23, which may be arranged around the opening 22. The second positioning hole 51 is provided in a one-to-one correspondence with the first positioning hole 23, and the second positioning hole 51 is provided on the housing cover 5 and penetrates the housing cover 5. The positioning pin is inserted into the first positioning hole 23 and the second positioning hole 51. The positioning pin can, on the one hand, achieve the purpose of positioning the housing cover 5 in the circumferential direction of the housing 2, so as to avoid the housing cover 5 from shifting or misaligning in the circumferential direction during long-term use. On the other hand, the positioning pin can also position the installation position of the housing cover 5 to prevent misinstallation. In addition, the specifications and quantity of the positioning pin and the corresponding first positioning hole 23 and second positioning hole 51 can be reasonably designed according to the actual mechanical strength requirements, such as 2, 3, or 4, etc., and this disclosure does not impose specific limitations in this regard.

[0053] In addition, in some other exemplary embodiments, the first positioning structure may also include a positioning block and a positioning groove. One of the housing 2 and the cover 5 may be provided with a positioning block, and the other of the housing 2 and the cover 5 may be provided with a positioning groove. The positioning block is inserted into the positioning groove to complete the positioning between the housing 2 and the cover 5.

[0054] Similarly, the second positioning structure can be constructed in any suitable form to achieve the purpose of positioning the cover 5 on the housing 2 in the radial direction of the housing 2, and this disclosure does not impose any specific limitations on this.

[0055] As an exemplary embodiment, reference is made to Figure 2 As shown, the cover 5 includes a cover body and a positioning flange 52. The second positioning structure includes the positioning flange 52, which can be constructed as an annular ring and connected to one side of the cover body. The positioning flange 52 extends into the opening 22, and the outer peripheral wall of the positioning flange 52 is used to fit against the inner wall of the opening 22. The positioning flange 52 can, on the one hand, achieve the purpose of positioning the cover 5 in the radial direction of the housing 2. On the other hand, when there is an interference fit between the outer peripheral wall of the positioning flange 52 and the inner wall of the housing 2, it can also play a certain pre-installation role for the cover 5. That is, when installing the cover 5, the first end of the cover 5 with the positioning flange 52 extends into the housing 2 through the opening 22. The cover 5 is temporarily connected to the housing 2 by the friction between the two. The cover 5 is rotated to adjust the installation position of the cover 5 so that the first positioning hole 23 on the housing 2 and the second positioning hole 51 on the cover 5 are aligned one-to-one. Then, the housing 2 and the cover 5 are fixedly connected by fasteners (such as the connecting bolts 6 below).

[0056] In some embodiments, the inner diameter of the positioning flange 52 may also be larger than the outer diameter of the housing 2 at the opening 22. In this way, when the cover 5 is installed, the positioning flange 52 can be fitted onto the outside of the housing 2, that is, the inner peripheral wall of the positioning flange 52 is in contact with the outer wall of the housing 2, which can also achieve the purpose of positioning the cover 5 on the housing 2 in the radial direction. This disclosure does not make any specific limitations in this regard.

[0057] In the housing assembly for an electric motor provided in this disclosure, the cover 5 can be detachably connected to the housing 2 in any suitable manner, and this disclosure does not impose any specific limitations in this regard. As an exemplary embodiment, refer to... Figure 3 and Figure 4As shown, the housing assembly may also include multiple connecting bolts 6. The housing 2 may be provided with multiple threaded holes 24 spaced around the opening 22. The housing cover 5 may be provided with multiple through holes 53, which correspond one-to-one with the threaded holes 24. The connecting bolts 6 pass through the corresponding through holes 53 and are threadedly connected to the corresponding threaded holes 24. In this way, whether it is necessary to fix the housing cover 5 to the housing 2 during motor assembly, or when the components inside the housing 2 malfunction and need to be disassembled for repair or replacement, the bolt connection method can achieve quick assembly and disassembly of the housing cover 5 and the housing 2. In addition, the bolt connection method can play a role in pre-installation. When installing the housing 2 and the housing cover 5, the housing cover 5 can be connected to the housing 2 with the connecting bolts 6 without tightening them. The housing 2 can be pushed and pulled to check whether the motor mover moves smoothly. After fine-tuning the installation position of the housing cover 5, the connecting bolts 6 are tightened to complete the fixation between the housing cover 5 and the housing 2. The number of connecting bolts 6 and corresponding through holes 53 and threaded holes 24 can be reasonably designed according to actual mechanical strength requirements, such as 4, 6 or 8, etc. This disclosure does not impose specific restrictions on this.

[0058] In some other embodiments, the cover 5 and the housing 2 can also be detachably connected by a snap-fit ​​connection to achieve both positioning and fixing functions. This disclosure does not impose any specific limitations on this.

[0059] In the housing assembly for motor provided in this disclosure, as an exemplary embodiment, the housing 2 may have a first end and a second end opposite to each other, and the first end and the second end may each have an opening 22 formed therein. The housing cover 5 may include a first housing cover 501 and a second housing cover 502. The first housing cover 501 and the second housing cover 502 may be detachably connected to the first end and the second end, respectively. That is, the two ends of the housing 2 may be detachably connected to the housing cover 5. During installation, the operator can select a suitable opening 22 according to the actual situation to install other components of the motor into the installation space, which is conducive to improving the assembly efficiency of the motor.

[0060] Based on the above technical solutions, and referring to Figure 2 and Figure 5 As shown in the figure, this disclosure provides an electric motor, which includes the housing assembly for the motor described above. The housing assembly has all the technical features of the housing assembly described above, and therefore will not be described in detail here.

[0061] In the motor provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2As shown, the motor includes a stator assembly, which includes a central rod 1. The housing assembly is provided with a through hole 21, and the central rod 1 is slidably inserted into the through hole 21. In this way, the housing assembly can reciprocate relative to the central rod 1 along the axial direction of the central rod 1, that is, the housing assembly can reciprocate relative to the stator assembly.

[0062] The motor also includes a mover assembly, which comprises a housing assembly and a guide rod 7. The center rod 1 may have a mounting hole 11, and the guide rod 7 can be connected to the housing assembly and slidably inserted into the mounting hole 11. In this way, the guide rod 7 can move axially relative to the center rod 1. Since the guide rod 7 is connected to the cover 5, and the cover 5 is connected to the housing 2, the guide rod 7 can drive the cover 5 and the housing 2 to move axially relative to the center rod 1. That is, the mover assembly can perform linear motion relative to the stator assembly, thereby achieving linear motion of the motor. Furthermore, by slidably inserting the guide rod 7 into the mounting hole 11 of the center rod 1, the guide rod 7 slides in contact with the hole wall of the mounting hole 11, guiding the movement of the guide rod 7, the cover 5, and the housing 2, preventing the housing 2 and the cover 5 from shaking during movement.

[0063] In the motor provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2 As shown, the motor may also include a first linear bearing 8 installed in the through hole 21. The center rod 1 passes through the first linear bearing 8 and slides in the through hole 21. The first linear bearing 8 can, on the one hand, play a certain positioning role for the upper end of the center rod 1, and on the other hand, enable the upper end of the center rod 1 to meet the requirements of perpendicularity and concentricity with the guide rod 7.

[0064] In the motor provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2 As shown, the motor may also include a second linear bearing 9 installed in the mounting hole 11. The guide rod 7 extends into the second linear bearing 9 and slides against the inner wall of the mounting hole 11 through the second linear bearing 9. The second linear bearing 9 can, on the one hand, provide a certain positioning function for the lower end of the center rod 1, and on the other hand, ensure that the lower end of the center rod 1 meets the requirements of perpendicularity and concentricity with the guide rod 7.

[0065] It should be noted that the first linear bearing 8 and the second linear bearing 9 in this disclosure can both be sliding bearings. Sliding bearings have a larger contact area and greater adaptability, thus having a higher load capacity and being able to resist high impact loads and edge loads. Furthermore, sliding bearings have excellent damping performance when operating at high speeds and low loads, which can extend the life of the sliding bearing itself and the two components in contact with the sliding bearing.

[0066] In the motor provided in this disclosure, as an exemplary embodiment, the center rod 1, housing 2, and guide rod 7 are coaxially arranged. Since the guide rod 7 is connected to the housing cover 5, and the housing cover 5 is detachably connected to the housing 2, this allows the center rod 1 to move linearly relative to the housing 2 and the guide rod 7 along the axial direction of the guide rod 7. In other words, the housing 2 and the guide rod 7 can move linearly relative to the center rod 1 along the axial direction of the guide rod 7, satisfying the linear motion requirements of the motor. Furthermore, the coaxiality of the guide rod 7, the center rod 1, and the housing 2 also prevents deflection, eccentricity, and other issues during movement.

[0067] In the motor provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2 and Figure 3 As shown, the housing assembly includes a cover 5 and a housing 2. The housing 2 has a first end and a second end opposite to each other. The first end may have an opening 22. The cover 5 includes a first cover 501, which may be disposed at the first end and cover the opening 22. A through hole 21 may be disposed in the housing 2 and located at the second end. A guide rod 7 may be connected to the first cover 501. In this disclosure, the first end of the housing 2 can be regarded as the side facing the suspension body, that is, the first cover 501 is arranged on the side of the housing 2 facing the suspension body (see reference). Figure 2 and Figure 3 As shown in the diagram, at this time, the through hole 21 is provided in the housing 2 and located at the second end for the center rod 1 to pass through, and the guide rod 7 is connected to the first housing cover 501 so that the first housing cover 501 and the housing 2 can move together relative to the center rod 1 along the axial direction of the center rod 1.

[0068] In the motors provided in this disclosure, the motors can be installed in any suitable manner at the desired location, and this disclosure does not impose any specific limitations in this regard. As an exemplary embodiment, reference is made to... Figure 4 As shown, the motor may also include a connecting arm 10, which can be connected to the guide rod 7 on opposite sides of the first cover 501. The end of the connecting arm 10 away from the first cover 501 has a connecting part 101 for connecting to an external structure. In this way, when the motor needs to be installed, the cover 5 can be fixed in the required position by the connecting arm 10. Since the cover 5 is fixed to the housing 2, the motor is fixed in the required position.

[0069] The connecting part 101 can be constructed in any suitable form according to actual installation requirements, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 4As shown, the connecting part 101 can be configured as a fork arm connected to the wheel end. The fork arm has a mounting groove 1011 and a connecting hole 1012. The mounting groove 1011 can be configured as a U-shaped groove, with connecting holes 1012 respectively provided on the two opposite walls of the U-shaped groove. During installation, the motor pushes the opening 22 of the U-shaped groove towards the external structure, causing the U-shaped groove to fit over the outside of the external structure. Bolts or other fasteners pass through the connecting holes 1012 to hold the external structure within the U-shaped groove, thus fixing the motor to the external structure. Furthermore, the shape of the mounting groove 1011 can be designed to match the shape of the external structure during actual installation; this disclosure does not impose specific limitations in this regard.

[0070] In the motor provided in this disclosure, as an exemplary embodiment, the guide rod 7, the connecting arm 10 and the first housing cover 501 can be an integral piece to simplify the connection between the various components of the motor, reduce the motor assembly process and assembly time, and improve the reliability of the motor structure. In addition, the integral molding implementation also has the characteristics of strong integrity, high quality control and small finished product error.

[0071] In the motor provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 6 As shown, the housing assembly may include a cover 5 and a housing 2. The housing 2 has a first end and a second end opposite to each other. The second end may have an opening 22. The cover 5 includes a second cover 502, which may be disposed at the second end and cover the opening 22. A through hole 21 may be disposed in the second cover 502. A guide rod 7 may be connected to the housing 2. In this disclosure, the second end of the housing 2 can be regarded as the side facing the vehicle body, that is, the second cover 502 is arranged on the side of the housing 2 facing the vehicle body (see reference). Figure 6 As shown in the diagram, at this time, the through hole 21 is provided in the second cover 502 and located at the second end for the center rod 1 to pass through, and the guide rod 7 is connected to the housing 2 so as to drive the second cover 502 and the housing 2 to move together relative to the center rod 1 along the axial direction of the center rod 1.

[0072] In the above-described manner, the motor may further include a connecting arm 10, which is connected to the housing 2. The end of the connecting arm 10 away from the housing 2 has a connecting portion 101 for connecting to an external structure. Thus, when the motor needs to be installed, the housing 2 is simply fixed in the desired position via the connecting arm 10, and the motor is thus fixed in the desired position. The connecting portion 101 can be constructed in any suitable form according to actual installation requirements, and this disclosure does not impose any specific limitations on it. As an exemplary embodiment, refer to... Figure 4As shown, the connecting part 101 is constructed as a fork arm connected to the wheel end. This fork arm can have the same technical features as the fork arm connected to the first housing cover 501, so it will not be described again in this disclosure. At this time, the guide rod 7, the connecting arm 10 and the housing 2 can be a single piece to simplify the connection between the various components of the motor, reduce the motor assembly process and assembly time, and improve the reliability of the motor structure. In addition, the one-piece molding implementation also has the characteristics of strong integrity, high quality control, and small finished product error.

[0073] In the motor provided in this disclosure, as an exemplary embodiment, the housing assembly may include a housing cover 5 and a housing 2. The housing 2 has a first end and a second end opposite to each other. The first end and the second end may each have an opening 22. The housing cover 5 may include a first housing cover 501 and a second housing cover 502. The first housing cover 501 and the second housing cover 502 may be detachably connected to the first end and the second end, respectively. A guide rod 7 is connected to the first housing cover 501, and a through hole 21 is provided in the second housing cover 502. That is, the two ends of the housing 2 may be detachably connected to the first housing cover 501 and the second housing cover 502, respectively. At this time, the side of the housing 2 facing the suspension assembly is the first end, the first housing cover is provided at the first end and is provided with the guide rod 7 and the connecting arm 10. The side of the housing 2 facing the vehicle body is the second end, the second housing cover is provided at the second end and is provided with a through hole 21 for the center rod 1 to pass through. During installation, the operator can select a suitable opening 22 according to the actual situation to install other components of the motor into the installation space, which facilitates the improvement of the assembly efficiency of the motor.

[0074] In the above-described configuration, the motor may further include a connecting arm 10 connected to the first housing cover 501. The end of the connecting arm 10 away from the first housing cover 501 has a connecting portion 101 for connecting to an external structure. Thus, when the motor needs to be installed, the first housing cover 501 is simply fixed in the desired position via the connecting arm 10. Since the first housing cover 501 is fixed to the first end of the housing, and the second end of the housing 2 is fixed to the second housing cover 502, the housing assembly is fixed in the desired position, i.e., the motor is fixed in the desired position. The connecting portion 101 can be constructed in any suitable form according to actual installation requirements; this disclosure does not impose specific limitations in this regard. As an exemplary embodiment, refer to... Figure 4As shown, the connecting part 101 can be configured as a fork arm connected to the wheel end. This fork arm can have the same technical features as the fork arm connected to the first housing cover 501 and the fork arm connected to the housing, so this disclosure will not repeat them again. At this time, the guide rod 7, the connecting arm 10 and the first housing cover 501 can be a single piece to simplify the connection between the various components of the motor, reduce the motor assembly process and assembly time, and improve the reliability of the motor structure. In addition, the one-piece molding implementation also has the characteristics of strong integrity, high quality control, and small finished product error.

[0075] In the motor provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2 As shown, the motor includes a mover assembly, which includes a magnetic element 3, and a stator assembly, which includes a coil winding 4. The magnetic element 3 can be fixedly connected to the inner circumferential wall of the housing 2. The coil winding 4 is wound around the center rod 1, and the magnetic element 3 is arranged around the coil winding 4. In this way, when the coil winding 4 is connected to an external power source and energized, a moving magnetic field can be formed between it and the magnetic element 3. At this time, by controlling the direction of the power supplied by the external power source, the repulsive or attractive force between the coil winding 4 and the magnetic element 3 can be controlled. Since the magnetic element 3 is fixed to the housing 2 by adhesive, the phase... The repulsive or attractive force can drive the magnetic component 3, thereby causing the housing 2 to move upward or downward relative to the central rod 1 along the axial direction of the central rod 1, realizing the linear reciprocating motion of the mover assembly relative to the stator assembly. By controlling the amount of power supplied by the external power source, the magnitude of the repulsive or attractive force generated between the coil winding 4 and the magnetic component 3 can be controlled, thereby controlling the speed at which the magnetic component 3 (or housing 2) moves upward or downward relative to the central rod 1 (or coil winding 4), that is, controlling the speed at which the mover assembly moves linearly and reciprocating relative to the stator assembly, ultimately achieving the actual motion state required by the motor.

[0076] Based on the above solutions, this disclosure also provides a shock absorber, which includes the above-mentioned motor. The motor has all the technical features of the above-mentioned motor, so it will not be described in detail here.

[0077] Based on the above solutions, this disclosure also provides a suspension assembly, which includes the above-mentioned shock absorber. The shock absorber has all the technical features of the above-mentioned shock absorber, so it will not be described in detail here.

[0078] In the suspension assembly provided in this disclosure, as an exemplary embodiment, the suspension assembly includes a suspension body, and the motor includes a stator assembly and a mover assembly. The mover assembly includes a housing assembly, which can be connected to the suspension body. The stator assembly can be used to connect to the vehicle body. Since the mover assembly can perform linear reciprocating motion relative to the stator assembly, that is, the housing assembly can drive the suspension body to move relative to the vehicle body, the movement of the housing assembly relative to the stator assembly can be controlled according to different actual driving conditions of the vehicle, thereby achieving the purpose of adjusting the stability of the vehicle body and improving the stability of the vehicle driving.

[0079] Based on the above solutions, this disclosure also provides a vehicle that includes the above-described suspension assembly, which has all the technical features of the above-described suspension assembly, and therefore will not be described in detail here.

[0080] In summary, when assembling the motor provided in this disclosure, firstly, the magnetic component 3 is installed in the installation space through the opening 22 at the bottom of the housing 2 and attached to the inner wall of the housing 2. Secondly, the first linear bearing 8 is assembled with the housing 2, and the second linear bearing 9 is assembled with the center rod 1. Then, the coil winding 4 is wound on the center rod 1. The center rod 1 is inserted into the installation space through the opening 22, and the upper end of the center rod 1 passes through the first linear bearing 8. Then, the end of the housing cover 5 with the guide rod 7 is pushed towards the housing 2 so that the guide rod 7 passes through the second linear bearing 9. Then, the installation position of the housing cover 5 is adjusted, and the positioning pin is inserted into the first positioning hole 23 and the second positioning hole 51. The housing cover 5 and the housing 2 are connected by the connecting bolt 6. Finally, the motor housing 2 is pushed and pulled to check whether the movement of the moving part assembly is smooth. If it is not smooth, the guide rod 7 and the center rod 1 are checked to see if they are in place and whether the machining dimensions of each part exceed the standard. If it is smooth, the connecting bolt 6 is tightened, and the motor assembly is completed.
