[0062] According to the first aspect of this application, please refer to Figure 1 The motor 1 provided in this disclosure includes a primary component 2 and a secondary component 3. The secondary component 3 is connected to the primary component 2 to enable relative movement between the secondary component 3 and the primary component 2. The motor 1 has a cavity 10, which is adapted to facilitate relative movement between the secondary component 3 and the primary component 2.

[0063] In this embodiment, the cavity 10 is disposed inside the motor 1, so that the cavity 10 and the motor 1 cooperate to realize the relative movement of the secondary component 3 and the primary component 2, thereby improving the utilization rate of the internal space of the motor 1.

[0064] In one embodiment, the cavity 10 is adapted to be filled with or emptied of a medium to facilitate relative movement between the secondary component 3 and the primary component 2.

[0065] The medium can be, but is not limited to, air; it can also be other gases, liquids, or solids.

[0066] It is understandable that by filling the cavity 10 with a medium to adjust the air pressure inside the cavity 10, the cavity 10 can cooperate with the motor 1 to promote the relative movement of the secondary component 3 and the primary component 2.

[0067] In one embodiment, please refer to Figure 1 The cavity 10 includes a first cavity 101 and a second cavity 102, which are independently arranged.

[0068] The cavity 10 may also include three or more independent cavities, all of which are used to facilitate the relative movement of the secondary component 3 and the primary component 2.

[0069] It is understandable that by setting the cavity 10 into two independent first cavities 101 and second cavities 102, the first cavities 101 and second cavities 102 can independently promote the relative movement of the secondary component 3 and the primary component 2, thereby enhancing the promotion effect.

[0070] In one embodiment, the cavity 10 includes a first cavity 101 disposed within the primary component 2.

[0071] It is understandable that placing the first cavity 101 inside the primary component 2 can reduce the space occupied by the first cavity 101 inside the motor 1.

[0073] The first spindle portion 201 is located near the wheel end.

[0074] It is understood that the first cavity 101 is disposed within the first spindle portion 201 to facilitate its interaction with the secondary component 3 to form the first cavity 101, thereby promoting the relative movement between the secondary component 3 and the primary component 2.

[0075] In one embodiment, please refer to Figure 2 and Figure 3 The primary component 2 further includes a primary iron core 22, wherein the primary iron core 22 is installed on the outer periphery of the first mandrel portion 201.

[0076] One end of the primary mandrel 21 is in transition fit with the primary iron core 22, and the other end of the primary mandrel 21 is threaded and connected to the vehicle body end.

[0077] The primary component 2 further includes a primary winding 23, which is sleeved on the outer periphery of the primary iron core 22.

[0078] It is understandable that by using the first mandrel portion 201 for mounting the primary iron core 22 and the primary winding 23 to form the cavity 10, the internal space of the electrode can be saved.

[0079] In one embodiment, please refer to Figure 2 and Figure 3 The primary component 2 further includes a first buffer 26, which is sleeved on the outer periphery of the primary mandrel 21; wherein the first buffer 26 is located on one side of the primary iron core 22 in the axial direction and is adapted to abut against the secondary component 3 to buffer the primary iron core 22.

[0080] The first buffer 26 can be made of an elastic material.

[0081] It is understandable that during the relative movement of the primary component 2 and the secondary component 3, the first buffer 26 is used to prevent the top of the primary iron core 22 from directly colliding with the top of the housing 32, thus playing a buffering role.

[0082] In one embodiment, please refer to Figure 2 and Figure 3 The primary component 2 is provided with a first air nozzle 40, which is adapted to connect to the first cavity 101 for inflation or deflation.

[0083] The first air nozzle 40 is also provided with a first valve body, which is used to control the opening and closing of the first air nozzle 40 to inflate or deflate the first cavity 101.

[0085] In one embodiment, please refer to Figure 2 and Figure 3 The primary spindle 21 includes a second spindle portion 202 connected to one end of the first spindle portion 201. The second spindle portion 202 is adapted to be connected to the vehicle body end, wherein the first air nozzle 40 is disposed in the second spindle portion 202.

[0086] The first air nozzle 40 is located inside the second spindle portion 202, which can save internal space of the motor 1.

[0088] It is understandable that the piston guide rod 31 is used to form a first cavity 101 together with the primary component 2. During the relative movement of the primary component 2 and the secondary component 3, the piston guide rod 31 can move axially within the first cavity 101 to cooperate with the first cavity 101 to promote the relative movement of the primary component 2 and the secondary component 3.

[0089] In one embodiment, please refer to Figure 7 and Figure 8 A first sealing element 38 is provided on the outer periphery of one end of the piston guide rod 31. The first sealing element 38 abuts against the cavity wall of the first cavity 101 to seal the first cavity 101.

[0090] The piston guide rod 31 is also surrounded by a second groove on its outer circumferential side, and a first seal 38 is disposed in the second groove.

[0091] The first seal 38 is elastic and is compressed by the cavity inner wall 27 of the primary mandrel 21 and is an interference fit.

[0092] The outer circumferential wall of the first sealing member 38 is provided with a diamond coating.

[0093] Understandably, the first seal 38 is used to seal the first cavity 101 to prevent air leakage from the first cavity 101 from affecting the promoting effect on the relative movement of the primary component 2 and the secondary component 3. The diamond coating on the outer periphery of the first seal 38 can reduce friction and improve wear resistance.

[0094] In one embodiment, please refer to Figure 6 The secondary component 3 includes a second buffer 36, which is adapted to abut against the primary component 2 along the axial direction of the motor 1 to buffer the primary component 2.

[0095] Understandably, the second buffer 36 is used to prevent the primary component 2 from directly impacting the base of the lower fork arm 33 and piston guide rod 31 during the high-speed descent of the vehicle. The second buffer 36 plays a role in buffering and protecting the vehicle.

[0096] In one embodiment, please refer to Figure 6 The second buffer 36 is sleeved on the outer periphery of the other end of the piston guide rod 31.

[0097] Understandably, directly fitting the second buffer 36 onto the outer periphery of the piston guide rod 31 facilitates the installation of the second buffer 36 and enables better buffering between the primary component 2 and the lower fork arm 33 and the base of the piston guide rod 31.

[0098] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 The primary component 2 further includes a locking member 24, which is installed on the primary component 2 and adapted to abut against one end of the piston guide rod 31 to axially limit the movement of the piston guide rod 31.

[0099] The locking member 24 has an external thread on its outer wall and an internal thread on the bottom end of the cavity inner wall 27 of the primary mandrel 21. The external thread and the internal thread engage to lock the primary iron core 22.

[0100] The locking element 24 can be a hexagonal nut head to facilitate locking the primary iron core 22.

[0101] Understandably, the locking element 24 is used to axially limit the piston guide rod 31 to prevent the piston guide rod 31 from shifting axially during the cloud process.

[0102] In one embodiment, please refer to Figure 2 and Figure 3 The primary component 2 further includes a primary mandrel 21 and a primary iron core 22, and the locking member 24 is installed on the primary mandrel 21 to install the primary iron core 22 on the primary mandrel 21.

[0103] Understandably, the locking member 24 is also used to install the primary iron core 22 onto the primary mandrel 21 and to lock the primary iron core 22.

[0104] In one embodiment, please refer to Figure 4 and Figure 5 The locking member 24 is provided with a second sealing member 25 on its outer periphery. The motor 1 is also provided with a second cavity 102. The second sealing member 25 abuts against the cavity wall of the second cavity 102 to seal the second cavity 102.

[0105] The second seal 25 can be made of an elastic material and is interference-fitted with the cavity wall of the second cavity 102.

[0106] Understandably, the second seal 25 is used to enhance the sealing of the second cavity 102 and prevent air leakage from the second cavity 102 from affecting the relative movement between the primary component 2 and the secondary component 3.

[0107] In one embodiment, the cavity 10 includes a second cavity 102 disposed within the secondary component 3.

[0108] Understandably, the second cavity 102 is located in the secondary component 3, which can improve the utilization rate of the internal space of the motor 1.

[0109] In one embodiment, please refer to Figure 2 and Figure 3 The secondary component 3 includes a housing 32, and the primary component 2 is movably disposed within the housing 32 to form at least a portion of the second cavity 102 with the secondary component 3.

[0110] It is understood that the second cavity 102 is formed by the primary component 2 and the secondary component 3. During the movement of the primary component 2 relative to the secondary component 3, the volume of the second cavity 102 will change. Air is injected or released into the second cavity 102 through the second air nozzle 50 to promote the relative movement of the secondary component 3 and the primary component 2.

[0111] In one embodiment, please refer to Figure 6 The secondary component 3 further includes a sliding bearing 37, and the primary component 2 includes a primary spindle 21. The sliding bearing 37 is sleeved on the outer periphery of the primary spindle 21 to restrict the radial movement of the primary spindle 21.

[0112] Understandably, the piston guide rod 31, the sliding bearing 37, and the locking element 24 together serve as a limiting element, ensuring that the motor 1 is always in axial reciprocating motion. At the same time, the sliding bearing 37 can also reduce friction and enhance wear resistance.

[0113] In one embodiment, please refer to Figure 6 The secondary component 3 further includes a magnetic element 34 and a partition 35 installed on the housing 32. The magnetic element 34 is adapted to move under the drive of the primary component 2 and is sleeved on the outer periphery of the primary component 2. The partition 35 is disposed between the primary component 2 and the magnetic element 34.

[0114] The partition 35 is used to block the magnetic component 34 and the primary component 2.

[0115] Among them, the partition 35 is made of non-magnetic material.

[0116] It is understood that the partition 35 abuts against the second sealing member 25, and the contact surface between the partition 35 and the second sealing member 25 is a flat surface to prevent the second sealing member 25 from directly colliding with the magnetic member 34. At the same time, the flat surface can reduce frictional resistance.

[0117] Understandably, the partition 35 serves to limit and press the magnetic component 34 during assembly, preventing the magnetic component 34 from detaching and breaking under conditions such as high-speed impact, thus affecting the normal operation of the entire machine.

[0118] In one embodiment, the partition 35 and the primary component 2 form at least a portion of the second cavity 102.

[0119] Understandably, the partition 35 and the primary component 2 form a second cavity 102 to improve the utilization of the internal space of the motor 1.

[0120] In one embodiment, please refer to Figure 6The secondary component 3 is provided with a second air nozzle 50, which is adapted to connect to the second cavity 102 for inflation or deflation.

[0121] The second air nozzle 50 is also equipped with a second valve body, which controls the opening or closing of the second air nozzle 50.

[0122] It is understandable that the air pressure inside the second cavity 102 is adjusted by the second air nozzle 50, so that the second cavity 102 promotes the relative movement of the secondary component 3 and the primary component 2.

[0123] In one embodiment, please refer to Figure 6 and Figure 9 The secondary component 3 further includes a lower fork 33 mounted on the housing 32, the lower fork 33 being adapted to connect to the wheel end, wherein the lower fork 33 is provided with the second valve 50.

[0124] The opening direction of the second air nozzle 50 can be the same as the axial direction.

[0125] Understandably, the second air nozzle 50 is located on the lower fork arm 33, which is directly below the second cavity 102, making it easier to form the second air nozzle 50. The manufacturing process is simple and the cost is lower.

[0126] In one embodiment, please refer to Figure 6 , Figure 7 , Figure 8 The secondary component 3 further includes a piston guide rod 31, one end of which is movably installed in the primary component 2, and the other end of which is installed in the lower fork arm 33.

[0127] It is understood that the two ends of the piston guide rod 31 are fixed to the lower fork arm 33 and movably mounted on the primary component 2, respectively. The piston guide rod 31 is used to control the volume of the first cavity 101 during the relative movement of the primary component 2 and the secondary component 3, so that the first cavity 101 cooperates with the first air nozzle 40 to promote the relative movement of the secondary component 3 and the primary component 2.

[0128] In one embodiment, please refer to Figure 7 , Figure 8 , Figure 9 The piston guide rod 31 has a limiting hole 60 at the other end, and the lower fork arm 33 has a limiting protrusion 39. The second air nozzle 50 passes through the limiting protrusion 39; wherein the limiting protrusion 39 passes through the limiting hole 60.

[0129] Understandably, the cooperation between the limiting hole 60 and the limiting protrusion 39 enables the piston guide rod 31 to be more tightly connected to the lower fork arm 33, thereby enhancing the connection strength between the piston guide rod 31 and the lower fork arm 33.

[0130] In one embodiment, the second air nozzle 50 is disposed on the housing 32.

[0131] Understandably, by placing the second air nozzle 50 in the housing 32, the lower fork 33 does not need to have an additional second air nozzle 50 formed, thus enhancing the structural strength of the lower fork 33.
