[0002] This application is based on and claims priority to Chinese Patent Application No. 202423106529.X, filed on December 16, 2024, entitled "Electric Motor, Suspension System and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of motor technology, specifically an electric motor, a suspension system, and a vehicle. Background Technology

[0004] In existing vehicles, the suspension system, as an elastic connection between the vehicle body and the wheels, can dampen and mitigate shocks when the vehicle is traveling on uneven roads, ensuring the vehicle's stability and improving the driving experience.

[0005] However, in most existing suspension systems, the mover and stator in the motor are prone to relative misalignment during operation, which affects the performance of the suspension system. Summary of the Invention

[0006] Therefore, this application proposes a motor that can limit the relative offset between the first component and the second component, so that the thrust and pull of the motor can be output stably, thereby improving the working efficiency of the motor and thus improving the working performance of the suspension system. This solves the technical problem in the prior art that the mover and stator in the motor are prone to relative offset, which affects the working performance of the suspension system.

[0007] The motor according to an embodiment of this application includes: a first component and a second component. The first component includes a first guide member, at least a portion of which is hollow to form a guide cavity. The second component includes a housing and a second guide member. The housing has a first opening and a second opening at its axial ends, respectively. One end of the first guide member passes through the first opening into the housing. The second guide member includes a support seat and a guide rod. The guide rod is movably fitted within the guide cavity. The support seat is disposed at the second opening. The guide rod is connected to the support seat. The outer peripheral wall of the support seat is interference-fitted with the inner peripheral wall of the housing.

[0008] According to the embodiments of this application, the motor forms a guide cavity inside at least a portion of the first guide member, and the guide rod of the second component is movably fitted within the guide cavity to achieve a guiding fit between the first and second components. This limits the relative movement direction of the first and second components during their relative movement, preventing friction caused by relative misalignment and thus avoiding damage to the motor, extending its service life. It also reduces resistance during motor operation, making the motor run more smoothly and ensuring its performance. Furthermore, by using an interference fit between the outer peripheral wall of the support base and the inner peripheral wall of the housing, the support base can be directly supported by the housing, achieving direct support of the second guide member. This centering of the guide rod improves its alignment, prevents misalignment relative to the guide cavity, and enhances the fit between the guide rod and the guide cavity.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0033] The motor 1100 of this application is described below with reference to the accompanying drawings.

[0034] As shown in Figures 1 and 2, the motor 1100 according to an embodiment of this application includes a first component 100 and a second component 200.

[0035] As shown in Figure 2, the first component 100 includes a first guide member 110, at least a portion of which is hollow to form a guide cavity 111. This can be understood as follows: by hollowing out at least a portion of the first guide member 110 to form the guide cavity 111, the molding difficulty of the guide cavity 111 is reduced, thus providing working space for the movement of the second component 200. Simultaneously, the guide cavity 111 facilitates the linear movement of the second component 200, ensuring the working performance of the motor 1100 to a certain extent.

[0036] Referring to Figures 1 and 2, the second component 200 includes a housing 210 and a second guide member 220. The housing 210 has a first opening and a second opening at its two axial ends, respectively. One end of the first guide member 110 passes through the first opening and is inserted into the housing 210. The second guide member 220 includes a support 221 and a guide rod 222. The guide rod 222 is movably fitted in the guide cavity 111. The support 221 is located at the second opening. The guide rod 222 is connected to the support 221. The outer peripheral wall of the support 221 is interference-fitted with the inner peripheral wall of the housing 210. This design allows for direct fixation of the support base 221 using the outer shell 210. The interference fit also enhances the fixation effect of the outer shell 210 on the support base 221, improving the positional stability of the support base 221 and consequently the positional stability of the second guide member 220. This achieves the purpose of centering the guide rod 222, which helps improve the alignment of the guide rod 222 when following the linear movement of the second component 200. This ensures the coaxiality of the guide rod 222 and the guide cavity 111, increases the relative stability of the first component 100 and the second component 200, and reduces the friction generated when the guide rod 222 and the guide cavity 111 move relative to each other, thus extending the service life of the guide rod 222 and the guide cavity 111.

[0037] In addition, ensuring the coaxiality of the guide rod 222 and the guide cavity 111 can improve the guiding accuracy of the entire second guide member 220. The cooperation between the guide rod 222 and the guide cavity 111 can effectively guide the movement of the second component 200, ensuring good centering of the second component 200 during movement, thereby reducing the motion resistance of the motor 1100 and improving the performance of the motor 1100.

[0038] Here, the axial direction can be understood as the up and down direction shown in Figures 1 and 2. By providing a first opening at one end of the axial direction of the housing 210, one end of the first guide 110 can be inserted into the housing 210, thereby facilitating the placement of at least a portion of the first guide 110 inside the housing 210. This facilitates the cooperation between the first component 100 and the second component 200, ensuring the working performance of the motor 1100 to a certain extent, while also allowing the housing 210 to better protect the first guide 110 from external interference.

[0039] Meanwhile, by providing a second opening at the other end of the axial direction of the housing 210, it is easier to install the second guide 220, reducing the difficulty of fitting the second guide 220 with the housing 210, and helping to ensure the working performance of the second guide 220.

[0040] In summary, by providing the first opening and the second opening at both axial ends of the housing 210, it can be understood that this is for better installation and disassembly of the parts that it mates with.

[0041] It is worth noting that this application splits the second component 200 into a housing 210 and a second guide member 220, and places the support seat 221 of the second guide member 220 in the second opening of the housing 210, so that the housing 210 and the second guide member 220 can be formed as separate parts. In this way, during the processing of the second component 200, the housing 210 and the second guide member 220 can be processed and formed separately, reducing the forming difficulty of the housing 210 and the second guide member 220. This makes it easier to movably fit the guide rod 222 of the second guide member 220 into the guide cavity 111 of the first guide member 110.

[0042] By movably fitting the guide rod 222 within the guide cavity 111, at least a portion of the second component 200 can be located within the first component 100. This facilitates the movement of the second component 200 using the guide rod 222 and the guide cavity 111, thereby preventing the second component 200 from shifting during movement and ensuring the accuracy of its movement. Simultaneously, it prevents the second component 200 from rubbing against the first component 100 due to shifting, thus avoiding damage to the motor 1100 and preventing increased thrust and pull forces due to friction. This improves the working efficiency of the motor 1100, reduces its energy loss, and to a certain extent guarantees its performance.

[0043] In other words, by setting the guide rod 222 and the guide cavity 111 to cooperate, the accuracy of the movement of the second component 200 can be guaranteed, which can not only extend the service life of the motor 1100, but also improve the working efficiency of the motor 1100.

[0044] As can be seen from the above structure, the motor 1100 of this application embodiment, by hollowing out at least part of the first guide member 110 to form a guide cavity 111, and movably fitting the guide rod 222 within the guide cavity 111, can guide the movement of the second component 200 by cooperating with the guide rod 222 and the guide cavity 111. This avoids the second component 200 from deviating during movement to a certain extent, ensuring the accuracy of the movement of the second component 200. At the same time, it avoids the second component 200 from rubbing against the first component 100 due to deviation. In addition to avoiding damage to the motor 1100, it also avoids the increase of the thrust and pull of the motor 1100 due to friction, thereby improving the working efficiency of the motor 1100, reducing the energy loss of the motor 1100, and ensuring the working performance of the motor 1100 to a certain extent.

[0045] Meanwhile, by interfering with the outer peripheral wall of the support base 221 and the inner peripheral wall of the outer shell 210, the outer shell 210 can be used to directly fix and support the support base 221, reducing the fit tolerance. The interfering fit can also improve the fixing and support effect of the outer shell 210 on the support base 221, thereby centering the guide rod 222. This helps to improve the centering of the guide rod 222 when it follows the linear movement of the second component 200, thus ensuring the coaxiality of the guide rod 222 and the guide cavity 111, improving the accuracy of the movement of the second guide component 220, and also improving the centering of the second component 200. This allows the guide rod 222 and the guide cavity 111 to effectively guide the movement of the second component 200, thereby enabling the motor 1100 to stably output thrust and pull.

[0046] Compared to existing technologies, it is understood that this application uses an interference fit between the outer peripheral wall of the support base 221 and the inner peripheral wall of the housing 210, reducing installation tolerances and shortening the dimensional chain, thereby improving the positional accuracy of the guide rod 222 and enhancing its centering. This is beneficial for improving the centering of the guide rod 222 when following the linear movement of the second component 200, thus ensuring the coaxiality of the guide rod 222 and the guide cavity 111. The cooperation between the guide rod 222 and the guide cavity 111 can effectively guide the movement of the second component 200, improving the working performance of the second guide member 220. This allows the thrust and pull of the motor 1100 to be output stably, improving the working efficiency of the motor 1100.

[0047] In some embodiments, the housing 210 is made of aluminum alloy, so that the housing 210 has good mechanical properties and excellent corrosion resistance, thereby enabling the housing 210 to better protect its internal components from external damage and extend the service life of the motor 1100.

[0048] In some examples, the aluminum alloy can be processed using a die-casting process to obtain the housing 210, reducing the difficulty of forming the housing 210.

[0049] In some embodiments, during the assembly of the support base 221 and the outer shell 210, at least a portion of the outer shell 210 at the outer periphery of the second opening can be heated first. After the outer shell 210 undergoes thermal deformation due to heating, the support base 221 is assembled to the second opening. After the outer shell 210 cools down, an interference fit can be achieved between the outer peripheral wall of the support base 221 and the inner peripheral wall of the outer shell 210, reducing the difficulty of fitting the support base 221 and the outer shell 210 and ensuring the quality of the fit.

[0050] In some embodiments, as shown in FIG2, the first component 100 further includes a coil winding 120, which is wound around at least a portion of the outer periphery of the first guide 110 and located inside the housing 210. The second component 200 further includes a magnet 240, which is disposed inside the housing 210. The coil winding 120 and the magnet 240 cooperate to achieve the coupling between the first component 100 and the second component 200, thereby enabling the second component 200 to reciprocate and ensuring the working performance of the motor 1100 to a certain extent.

[0051] In some examples, the coil winding 120 is energized, and the energized coil winding 120 generates a magnetic field, causing the magnet 240 to move linearly. At this time, the coil winding 120 and the magnet 240 cooperate to achieve the coupling of the first component 100 and the second component 200 (the cooperation of the coil winding 120 and the magnet 240 to realize the working principle of the motor 1100 is existing technology and will not be described in detail here), thereby enabling the second component 200 to reciprocate and achieve the purpose of vibration reduction.

[0052] It should be noted that by winding the coil winding 120 around at least part of the outer periphery of the first guide member 110, the first guide member 110 can be used to support the coil winding 120, thereby improving the positional stability of the coil winding 120 and ensuring the working performance of the coil winding 120 to a certain extent.

[0053] Meanwhile, by placing the magnet 240 inside the housing 210, while ensuring that the coil winding 120 and the magnet 240 can achieve the coupling and cooperation of the first component 100 and the second component 200, the housing 210 can also support and protect the magnet 240, improve the positional stability of the magnet 240, and extend the service life of the magnet 240.

[0054] In some embodiments, the magnet 240 is a rare-earth permanent magnet material to facilitate the generation of a stable magnetic field.

[0055] In some examples, motor 1100 is a suspended motor. This allows motor 1100 to effectively buffer and absorb vibrations when it is installed in vehicle 2000.

[0056] In some examples, the first component 100 is a stator component, the second component 200 is a mover component, and the first guide 110 is formed as a stator mandrel 110.

[0057] In some embodiments, the extension length of the outer peripheral wall of the support base 221 in the axial direction of the motor 1100 ranges from 4mm to 10mm. Here, the extension length of the outer peripheral wall of the support base 221 can be understood as L1 as shown in Figure 3. When the extension length of the outer peripheral wall of the support base 221 is too short, it will reduce the fit strength between the support base 221 and the housing 210; when the extension length of the outer peripheral wall of the support base 221 is too long, it will increase the space occupied by the support base 221 inside the motor 1100, affecting the installation of the magnet 240 and hindering the installation arrangement of the internal space of the motor 1100.

[0058] In summary, this application sets the extension length of the outer peripheral wall of the support base 221 to a range of 4mm-10mm. This ensures that the outer peripheral wall of the support base 221 can effectively cooperate with the inner peripheral wall of the outer shell 210, while also preventing the support base 221 from occupying too much space inside the motor 1100, facilitating the installation of the magnet 240, and thus reducing the assembly difficulty of the motor 1100.

[0059] In some examples, the extension length of the outer peripheral wall of the support 221 is 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm, etc.

[0060] In some embodiments, the support base 221 and the guide rod 222 are formed as a single piece. This allows the support base 221 and the guide rod 222 to be manufactured using a one-piece molding process, reducing the molding difficulty of the support base 221 and the guide rod 222. It also eliminates the need for a separate connection between the support base 221 and the guide rod 222, ensuring the connection quality of the support base 221 and the guide rod 222. This facilitates the formation of the second guide member 220, reduces the molding difficulty of the second guide member 220, and improves the structural strength of the second guide member 220, thereby ensuring the working performance of the second guide member 220 to a certain extent.

[0061] In some embodiments, during the production and processing of the second guide member 220, a grinding forming process can be used to make the support base 221 and the guide rod 222 form a single piece.

[0062] The grinding process also makes the coaxiality of the outer peripheral surface of the guide rod 222 and the outer peripheral wall of the support 221 very small. As a result, the positioning mating surfaces of the outer peripheral surface of the guide rod 222 and the outer peripheral wall of the support 221 can be formed as a concentric structure. When the support 221 is positioned, the guide rod 222 can be centered, which helps to improve the centering of the second component 200 and to a certain extent avoids the offset of the second component 200 relative to the first component 100 when it moves, thereby reducing the motion resistance of the motor 1100 and improving the performance of the motor 1100.

[0063] Of course, in some other embodiments, the support base 221 and the guide rod 222 can also be formed as separate parts. That is, the support base 221 and the guide rod 222 are processed and formed separately, and then the support base 221 and the guide rod 222 are connected (e.g., by welding, bonding or other connection methods) to form the second guide member 220.

[0064] In some embodiments, as shown in FIG4, the support base 221 and the guide rod 222 are connected by an arc segment 223. This can be understood as the arc segment 223 transitioning at the connection between the support base 221 and the guide rod 222, effectively resisting deformation, reducing stress concentration, and to some extent preventing breakage at the connection, thus extending the service life of the second guide member 220 and improving its structural strength, thereby ensuring its performance to a certain extent.

[0065] In some embodiments, as shown in Figures 2 and 3, the motor 1100 further includes a buffer 300. The buffer 300 is sleeved on the outer periphery of the second guide 220 and located between the first guide 110 and the support 221. The buffer 300 is used to buffer the relative displacement of the first component 100 and the second component 200. This achieves the purpose of limiting the maximum movement position of the second component 200 and can effectively reduce the impact force when the second component 200 contacts the first component 100, thereby avoiding rigid contact between the first component 100 and the second component 200, and thus extending the service life of the motor 1100.

[0066] In some embodiments, the buffer 300 may be made of materials such as rubber or silicone to ensure the buffering performance of the buffer 300.

[0067] In some embodiments, as shown in Figures 3 and 4, the support base 221 has a first mounting groove 224 on the side facing the first guide member 110, and at least a portion of the buffer member 300 is disposed within the first mounting groove 224. This helps to reduce the axial height of the buffer member 300 relative to the second guide member 220, and avoids excessively reducing the relative position between the second component 200 and the first component 100 due to the installation of the buffer member 300, thereby increasing the travel stroke of the motor 1100 and ensuring the working performance of the motor 1100 to a certain extent.

[0068] In other words, by setting the first mounting groove 224 and placing at least part of the buffer 300 in the first mounting groove 224, it is possible to reduce the impact force when the second component 200 contacts the first component 100 using the buffer 300, while also increasing the stroke of the motor 1100.

[0069] In some embodiments, the depth of the first mounting groove 224 is in the range of 3mm-6mm. When the depth of the first mounting groove 224 is too shallow, it is not conducive to increasing the movement stroke of the motor 1100; when the depth of the first mounting groove 224 is too deep, it is easy to reduce the thickness of the support 221 and reduce the structural strength of the support 221.

[0070] In summary, this application sets the groove depth of the first mounting groove 224 to a range of 3mm-6mm. This allows at least some of the buffers 300 to be placed in the first mounting groove 224, increasing the stroke of the motor 1100, while also giving the support 221 a certain thickness, improving the structural strength of the support 221, and ensuring the working performance of the support 221 to a certain extent.

[0071] In some examples, the depth of the first mounting slot 224 is 3mm, 4mm, 5mm or 6mm, etc.

[0072] In some embodiments, as shown in FIG2, a first guide bearing 400 is provided between the first guide member 110 and the inner peripheral wall of the first opening. The first guide bearing 400 is used to guide the movement of the second component 200, thereby preventing the second component 200 from deviating during the movement and ensuring the accuracy of the movement of the second component 200.

[0073] Meanwhile, the first guide bearing 400 can also reduce wear between the first component 100 and the second component 200, extend the service life of the motor 1100, reduce the motion resistance of the motor 1100, and improve the performance of the motor 1100.

[0074] In some embodiments, the first guide bearing 400 is disposed in the first opening and fixedly connected to the housing 210. The first guide bearing 400 is slidably engaged with the first guide member 110 to realize that the first guide bearing 400 is disposed between the first guide member 110 and the inner peripheral wall of the first opening, and to facilitate the use of the housing 210 to support the first guide bearing 400, thereby improving the positional stability of the first guide bearing 400 and ensuring the working performance of the first guide bearing 400 to a certain extent.

[0075] In some embodiments, as shown in Figures 2 and 3, a second guide bearing 500 is provided between the guide rod 222 and the inner peripheral wall of the guide cavity 111. The second guide bearing 500 is used to guide the movement of the second component 200, thereby preventing the second component 200 from deviating during movement and ensuring the accuracy of the movement of the second component 200.

[0076] Meanwhile, the second guide bearing 500 can also reduce wear between the first component 100 and the second component 200, extend the service life of the motor 1100, reduce the motion resistance of the motor 1100, and improve the performance of the motor 1100.

[0077] In some embodiments, the second guide bearing 500 is disposed in the guide cavity 111 and fixedly connected to the first guide member 110. The second guide bearing 500 is slidably engaged with the guide rod 222 to realize that the second guide bearing 500 is disposed between the guide rod 222 and the inner peripheral wall of the guide cavity 111, and to facilitate the use of the first guide member 110 to support the second guide bearing 500, thereby improving the positional stability of the second guide bearing 500 and ensuring the working performance of the second guide bearing 500 to a certain extent.

[0078] In some embodiments, as shown in Figures 2 and 3, a first guide bearing 400 is provided between the first guide member 110 and the inner peripheral wall of the first opening, and a second guide bearing 500 is provided between the guide rod 222 and the inner peripheral wall of the guide cavity 111. That is, the motor 1100 is simultaneously provided with the first guide bearing 400 and the second guide bearing 500. The cooperation of the first guide bearing 400 and the second guide bearing 500 ensures the accuracy of the movement of the second component 200 while also reducing the mutual friction between the first component 100 and the second component 200, preventing the motor 1100 from overheating, thereby preventing damage to the motor 1100 and extending its service life.

[0079] It should be noted that by positioning the support base 221 using the outer shell 210, the coaxiality of the guide rod 222 with the first guide bearing 400 and the second guide bearing 500 can be ensured, thereby ensuring the coaxiality of the second component 200 with the first component 100 during relative linear motion. This allows the thrust and pull of the motor 1100 to be output stably, and improves the service life of the components and the overall structure of the motor 1100.

[0080] Optionally, both the first guide bearing 400 and the second guide bearing 500 are formed as graphite copper bearings. This ensures that both the first guide bearing 400 and the second guide bearing 500 have good wear resistance, thereby extending their service life.

[0081] With the above settings, in some examples, when assembling the mover assembly 200, the buffer 300 is first fitted onto the outer periphery of the guide 220. When installing the second guide 220, at least part of the outer periphery of the second opening can be heated first. After the outer periphery of the outer periphery of the outer periphery of the outer periphery of the second opening is deformed by heating, the support 221 is assembled to the second opening, and the guide rod 222 is movably fitted into the guide cavity 111. After the outer periphery of the outer periphery of the outer periphery of the support 221 and the inner periphery of the outer ...

[0082] In summary, the motor 1100 of this application directly positions the support base 221 by interfering with the outer peripheral wall of the support base 221 and the inner peripheral wall of the housing 210. Compared with the prior art, this reduces the installation tolerance and shortens the dimensional chain, thereby greatly improving the coaxiality of the guide rod 222 and the first guide bearing 400 and the second guide bearing 500. This improves the coaxiality of the three components to a certain extent, ensuring that the guide component 220 can maintain good alignment when the motor 1100 is in tension or compression motion. This not only avoids energy loss and low power transmission efficiency, but also reduces friction, vibration and noise, making the operation of the motor 1100 smoother and reducing wear and fatigue of the motor 1100 components, thus extending the service life of the motor 1100.

[0083] The suspension system 1000 of this application embodiment is described below.

[0084] The suspension system 1000 according to an embodiment of this application includes a motor 1100.

[0085] Among them, motor 1100 is the aforementioned motor 1100, and the specific structure of motor 1100 will not be described in detail here.

[0086] According to the embodiments of this application, the suspension system 1000 can improve its working efficiency and enhance its shock absorption capacity by employing the aforementioned motor 1100, thereby ensuring the working performance of the suspension system 1000 to a certain extent.

[0087] In some embodiments, as shown in Figures 1, 2, and 3, the suspension system 1000 further includes a connecting arm 230, which is disposed at the second opening and fixedly connected to the housing 210. At least a portion of the outer peripheral wall of the support seat 221 abuts against the connecting arm 230. By abutting against the connecting arm 230 with at least a portion of the outer peripheral wall of the support seat 221, the support seat 221 can be directly fixed and supported by the connecting arm 230, further improving the positional stability of the support seat 221. This achieves the purpose of centering the guide rod 222, improving the alignment of the guide rod 222 when following the linear movement of the second component 200. This helps to improve the alignment of the guide rod 222 when following the linear movement of the second component 200, thereby ensuring the coaxiality of the guide rod 222 and the guide cavity 111, and thus improving the guiding accuracy of the entire second guide member 220.

[0088] In summary, this application utilizes the connecting arm 230 and the housing 210 to simultaneously and directly position the support base 221, maximizing the positional stability of the support base 221. This, in turn, improves the positional stability of the second guide member 220, facilitating the improvement of the accuracy of the movement of the second guide member 220. It also enhances the centering of the second component 200, enabling the guide rod 222 and the guide cavity 111 to effectively guide the movement of the second component 200, thereby allowing the motor 1100 to stably output thrust and pull.

[0089] Meanwhile, by setting a connecting arm 230 and fixing the connecting arm 230 to the housing 210, the housing 210 and the vehicle 2000 can be connected in a cooperative manner, thereby realizing the cooperative connection between the second component 200 and the vehicle 2000 and reducing the difficulty of the cooperative connection between the second component 200 and the vehicle 2000. This makes it easier to install the suspension system 1000 on the vehicle 2000 and achieve the purpose of using the suspension system 1000 to reduce vibration.

[0090] In some embodiments, the first component 100 is adapted to be connected to the body end of the vehicle 2000, and the second component 200 is adapted to be connected to the wheel end of the vehicle 2000 via a connecting arm 230. As the wheel moves up and down relative to the body, the second component 200 moves relative to the first component 100 to buffer the impact transmitted from the road surface.

[0091] Of course, in some other embodiments, the first component 100 may be connected to the wheel end of the vehicle 2000, and the second component 200 may be connected to the body end of the vehicle 2000 via the connecting arm 230.

[0092] Optionally, as shown in Figures 2 and 3, the suspension system 1000 further includes a first bolt 232. The connecting arm 230 is provided with a first bolt mounting hole (not shown in the figure). The first bolt 232 passes through the first bolt mounting hole and is fixedly connected to the housing 210 to realize the fixed connection between the connecting arm 230 and the housing 210, reduce the difficulty of fixing the connecting arm 230 and the housing 210, and facilitate the improvement of the fixed connection quality between the connecting arm 230 and the housing 210, so that the connecting arm 230 and the housing 210 form a stable connection, thereby stabilizing the relative position of the connecting arm 230 and the housing 210. In this way, the connecting arm 230 and the housing 210 can be used to directly position the support seat 221 simultaneously, further enhancing the installation accuracy of the second guide 220 and facilitating the use of the second guide 220 to improve the centering of the second component 200.

[0093] In some embodiments, the suspension system 1000 includes a plurality of first bolts 232, which cooperate to fix the connecting arm 230 and the housing 210, effectively improving the quality of the fixed connection between the connecting arm 230 and the housing 210.

[0094] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0095] In some embodiments, as shown in Figures 2 and 3, the connecting arm 230 has a second mounting groove 231 on the side facing the second opening, and at least a portion of the support seat 221 is disposed within the second mounting groove 231. The outer peripheral wall of the support seat 221 abuts against the inner peripheral wall of the second mounting groove 231. This achieves a stop-fit ​​between at least a portion of the outer peripheral wall of the support seat 221 and the connecting arm 230, reducing the difficulty of the stop-fit ​​between the support seat 221 and the connecting arm 230. This facilitates the use of the connecting arm 230 to fix and support the support seat 221, further improving the positional stability of the support seat 221. This makes the positioning and engagement of the second guide member 220 more precise, thereby improving the centering of the linear movement of the guide rod 222 and further enhancing the centering of the second component 200.

[0096] In some embodiments, as shown in Figures 2 and 3, along the axial direction of the motor 1100, a portion of the support 221 is disposed within the second mounting groove 231, and another portion of the support 221 extends out of the second mounting groove 231 and is located within the housing 210. This facilitates a stop-fit ​​between the outer peripheral wall of at least a portion of the support 221 and the inner peripheral wall of the second mounting groove 231, as well as an interference fit between the outer peripheral wall of at least a portion of the support 221 and the inner peripheral wall of the housing 210. This allows for simultaneous and direct positioning of the support 221 using both the connecting arm 230 and the housing 210, thereby maximizing the positional stability of the support 221.

[0097] In some embodiments, the support base 221 is fixedly connected to the connecting arm 230. This can be understood as follows: after at least a portion of the support base 221 is disposed within the second mounting groove 231 of the connecting arm 230, the support base 221 is fixedly connected to the connecting arm 230, so that the support base 221 can be stably disposed within the second mounting groove 231. This facilitates the abutment fit between the outer peripheral wall of the support base 221 and the inner peripheral wall of the second mounting groove 231, which is beneficial to improving the installation accuracy of the support base 221.

[0098] Optionally, as shown in Figures 3 and 4, the suspension system 1000 further includes a second bolt 225. The support seat 221 is provided with a second bolt mounting hole 226. The second bolt 225 passes through the second bolt mounting hole 226 and is fixedly connected to the connecting arm 230, so as to realize the fixed connection between the support seat 221 and the connecting arm 230, reduce the difficulty of the fixed connection between the support seat 221 and the connecting arm 230, and facilitate the improvement of the fixed connection quality between the support seat 221 and the connecting arm 230.

[0099] In some embodiments, as shown in FIG4, the support base 221 is provided with a plurality of second bolt mounting holes 226. The plurality of second bolt mounting holes 226 cooperate to realize the fixed connection of the support base 221 and the connecting arm 230 by using a plurality of second bolts 225, effectively improving the fixed connection quality of the support base 221 and the connecting arm 230.

[0100] In the description of this application, features marked with "first" or "second" may explicitly or implicitly include one or more of the same feature, used to distinguish and describe features, without any order or emphasis.

[0101] With the above settings, in some examples, when assembling the second component 200, the buffer 300 is first fitted onto the outer periphery of the second guide 220, and the support 221 is fixedly connected to the connecting arm 230 by the second bolt 225. When installing the connecting arm 230, at least part of the outer shell 210 at the outer periphery of the second opening can be heated first. After the outer shell 210 is deformed by heating, the support 221 is assembled to the second opening, and the guide rod 222 is movably fitted into the guide cavity 111. After the outer shell 210 cools down, the outer peripheral wall of the support 221 and the inner peripheral wall of the outer shell 210 can be interference-fitted to limit the second guide 220. Finally, the connecting arm 230 is fixedly installed on the outer shell 210 by the first bolt 232, thereby ensuring the coaxiality of the guide rod 222 with the first guide bearing 400 and the second guide bearing 500, which is beneficial to ensuring the coaxiality of the second component 200 and the first component 100 during relative linear movement.

[0102] In some embodiments, as shown in Figures 1 and 2, the suspension system 1000 further includes a first spring seat 600, a second spring seat 610, and a spring 700. The first component 100 is fixed to the vehicle frame via the first spring seat 600. The second spring seat 610 is fixedly connected to the outer periphery of the housing 210. The spring 700 is sleeved between the first spring seat 600 and the second spring seat 610 and is fixedly connected to the first spring seat 600 and the second spring seat 610 respectively. When the motor 1100 is working, internal damping is generated. The spring 700 can absorb and buffer the damping to reduce vibration and ensure the working stability of the motor 1100.

[0103] In some embodiments, as shown in Figures 1 and 2, the suspension system 1000 further includes a dust cover 800 and a three-phase connector 900. The dust cover 800 is mainly used to prevent external dust and water from entering the motor 1100, which is beneficial to the normal operation of the motor 1100; the three-phase connector 900 facilitates power supply to the motor 1100, which to a certain extent ensures the working performance of the motor 1100.
