[0046] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, in which 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 by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] First, refer to Figure 1A simple description of the vehicle 1000 according to an embodiment of the second aspect of the present invention is given.

[0048] As Figure 1 shown, the vehicle 1000 includes a vehicle body 200 and a frame 300. The vehicle body 200 is arranged on the upper side of the frame 300 and is connected to the frame 300 through a body mount 100.

[0049] Next, reference is made to Figures 1 - 10 describe the body mount 100 according to an embodiment of the first aspect of the present invention.

[0050] As Figures 1 - 10 shown, the body mount 100 according to an embodiment of the first aspect of the present invention includes: a mount cylinder 20, a movable rod 10, a motor primary 34, and a motor secondary 35.

[0051] Specifically, the mount cylinder 20 has a receiving cavity 203. One end of the mount cylinder 20 is used to connect to one of the vehicle body 200 and the frame 300; one end of the movable rod 10 extends into the receiving cavity 203 and can move relative to the mount cylinder 20, and the other end of the movable rod 10 is used to connect to the other of the vehicle body 200 and the frame 300; one of the motor primary 34 and the motor secondary 35 is provided on the mount cylinder 20 and the other is provided on the movable rod 10.

[0052] In this embodiment, one end of the mount cylinder 20 is connected to one of the vehicle body 200 and the frame 300, and the other end of the movable rod 10 is connected to the other of the vehicle body 200 and the frame 300. The two ends of the mount cylinder 20 refer to the two ends of the mount cylinder 20 in its length direction (such as Figure 1 the up and down direction shown). When one end of the mount cylinder 20 is connected to the vehicle body 200, the other end of the movable rod 10 can be connected to the frame 300. When the other end of the mount cylinder 20 is connected to the frame 300, the other end of the movable rod 10 is connected to the vehicle body 200. This can enable the mount cylinder 20 and the movable rod 10 to determine the layout relationship in the up and down direction according to needs when being installed and arranged between the frame 300 and the vehicle body 200, making the layout of the body mount 100 more flexible and convenient.

[0053] In this embodiment, the motor primary 34 and the motor secondary 35 are provided. One of the motor primary 34 and the motor secondary 35 is provided on the mount cylinder 20 and the other is provided on the movable rod 10. For example, when the motor primary 34 is provided on the mount cylinder 20, the motor secondary 35 is provided on the movable rod 10. When the motor primary 34 is provided on the movable rod 10, the motor secondary 35 is provided on the mount cylinder 20. The specific layout positions of the motor primary 34 and the motor secondary 35 can be reasonably arranged according to actual installation needs.

[0054] It can be understood that the motor primary 34 and the motor secondary 35 can cooperate to form a linear motor structure. The motor primary 34 is usually provided with a coil winding, and the motor secondary 35 is usually provided with a permanent magnet. When current is passed through the coil winding in the motor primary 34, the magnetic field generated and the magnetic field of the permanent magnet form a force, causing the motor primary 34 and the motor secondary 35 to move relative to each other, so that the suspension tube 20 and the movable rod 10 can move relative to each other under the driving action of the linear motor primary 34 and the motor secondary 35, and then the height of the vehicle body 200 can be actively adjusted to adapt to different vibration conditions.

[0055] For example, when the vehicle 1000 bounces upward, the motor primary 34 and the motor secondary 35 can cooperate to drive the body 200 to move toward the frame 300 to offset the upward bounce amplitude of the body 200. When the vehicle 1000 bounces downward, the motor primary 34 and the motor secondary 35 can cooperate to drive the body 200 to move upward away from the frame 300 to offset the downward bounce amplitude of the body 200. The linear machine structure formed by the combination of the motor primary 34 and the motor secondary 35 has fast response and high precision. The height of the body 200 can be adjusted faster and more accurately according to the bumps and vibrations of the vehicle 1000, thereby playing a good role in buffering, reducing vibration and isolating vibrations, making the vehicle 1000 more stable during cornering, going through potholes, accelerating, etc., and the body 200 can achieve the best riding state, making the driver and passengers feel more comfortable when riding.

[0056] In this embodiment, through the cooperation between the motor primary 34 and the motor secondary 35, the vehicle body suspension 100 can actively adjust the bumps and vibrations of the vehicle 1000, so that the vehicle 1000 can better adapt to flat and bumpy roads and better achieve the effect of vibration reduction and buffering during cornering, crossing potholes, acceleration and other working conditions, and play a better vibration isolation role for the vehicle body 200 and the frame 300, making the driver and passengers more comfortable when riding, and the driving experience can be greatly improved.

[0057] According to the vehicle body suspension 100 of the embodiment of the present invention, by providing a suspension tube 20 and a movable rod 10 that slides with the suspension tube 20, the motor primary 34 is provided in one of the suspension tube 20 and the movable rod 10 and the motor secondary 35 is provided in the other of the suspension tube 20 and the movable rod 10, it can play a good active buffering and vibration reduction role for the bumpy vibration of the vehicle body 200 and the frame 300 during the driving of the vehicle 1000, so that the vehicle body 200 is more stable during the driving of the vehicle 1000, thereby greatly improving the comfort of the driver and passengers when riding.

[0058] In some embodiments of the present invention, Figure 2As shown, the vehicle body mount 100 may further include a piston 40. The piston 40 is fixedly connected to one end of the movable rod 10. The piston 40 is disposed in the accommodation cavity and is slidably engaged with the mount cylinder.

[0059] In this embodiment, a piston 40 is fixed to one end of the movable rod 10. The piston 40 can play a certain guiding role in the movement of the movable rod 10 in the accommodation cavity 203, so that the movable rod 10 can reciprocate more stably along the length direction of the mount cylinder 20, thereby making the vehicle body mount 100 more stable and reliable during use.

[0060] In an embodiment of the present invention, with reference to Figure 2 As shown, the piston 40 may be formed with a flow hole. The flow hole communicates the spaces on both sides of the piston 40 in the length direction of the mount cylinder 20. The accommodation cavity 203 is filled with damping fluid.

[0061] In this embodiment, the accommodation cavity 203 is filled with damping fluid. The piston 40 is formed with a flow hole that penetrates the spaces of the accommodation cavity 203 on both sides of the piston 40. When the movable rod 10 reciprocates along the length direction of the mount cylinder 20 for buffering and vibration reduction, the piston 40 reciprocates in the accommodation cavity 203, causing the spaces of the accommodation cavity 203 on both sides of the piston 40 to change continuously, so that the damping fluid in the accommodation cavity 203 passes through the flow hole and reciprocates between the spaces on both sides of the piston 40.

[0062] During the process of the damping fluid passing through the flow hole, the internal friction between the hole wall and the oil molecules of the oil forms a damping force on the movement of the piston 40, thereby suppressing the movement of the piston 40, and further suppressing the movement of the movable rod 10 caused by the vehicle 1000 bumping and vibrating, so as to achieve the role of hydraulic damping and vibration reduction. When the active vibration reduction of the motor primary 34 and the motor secondary 35 fails, the cooperation between the piston 40 and the damping fluid can still play a good role in buffering and vibration reduction, and can make the vehicle body mount 100 maintain a good support stiffness, thereby reducing the risk of the vehicle body mount 100 failing in vibration reduction and isolation, improving the reliability of the vehicle body mount 100 in buffering and vibration reduction, and enabling the vehicle body mount to support the vehicle body more stably.

[0063] In this embodiment, the damping fluid can cooperate with the motor primary 34 and the motor secondary 35 to buffer and damp the vehicle body 200 and the vehicle frame 300, so that the vehicle body mount 100 can better buffer and damp the vehicle 1000, make the vehicle body 200 more stable during the driving of the vehicle 1000, and thus better improve the riding comfort of the passengers. Optionally, the damping fluid can be oil.

[0064] It can be understood that with reference to Figure 10As shown, when the motor primary 34 cooperates with the motor secondary 35 to perform active buffering and vibration reduction operations on the vehicle body 200 and the vehicle frame 300, an energy supply unit such as a battery or a capacitor of the vehicle 1000 needs to supply electrical energy to the motor primary 34 through an energy supply circuit. The motor primary 34 needs to consume electrical energy to operate. In this embodiment, by filling the damping liquid in the accommodation cavity 203 to form a hydraulic damping vibration reduction, it can cooperate with the active vibration reduction to perform vibration reduction operations. Thus, when the vehicle body mount 100 is operating, the linear motor structure formed by the motor primary 34 and the motor secondary 35 can consume electrical energy only when actively providing force, thereby reducing the active vibration reduction time and power consumption of the linear motor structure, reducing the use cost of the vehicle body mount 100 to a certain extent, and being beneficial to the endurance of the vehicle 1000. Since the motor primary 34 generates heat during operation, the oil in the accommodation cavity 203 can play a good role in heat conduction and dissipation for the motor primary 34, making the linear motor structure operate more stably in the vehicle body mount 100.

[0065] Further, referring to Figure 10 As shown, the vehicle body mount 100 may further include a sensor and a controller. The sensor may be disposed in the vehicle body 200 and communicatively connected to the controller, and the controller may be electrically connected to the motor primary 34. When the vehicle body mount 100 performs buffering and vibration reduction on the vehicle body 200, the sensor can detect the tilt angle of the vehicle body 200 and transmit the information to the controller. The controller controls the cooperation of the motor primary 34 and the motor secondary 35 according to the obtained information, and then controls the active movement of the movable rod 10 and the mount cylinder 20 along the length direction to achieve active buffering and shock absorption. Preferably, the sensor is a horizontal gyroscope sensor.

[0066] In some embodiments of the present invention, as Figure 2 shown, the mount cylinder 20 may include: an outer cylinder 21 and an inner cylinder 22. The outer cylinder 21 is sleeved outside the inner cylinder 22. Both ends of the inner cylinder 22 are hermetically connected to the outer cylinder 21 to cooperate to form a cavity 202, and the motor primary 34 is disposed in the cavity 202.

[0067] In this embodiment, the mount cylinder 20 is set to a double-cylinder structure with an inner cylinder 22 and an outer cylinder 21, so that the mount cylinder 20 has higher structural strength. The vehicle body mount 100 can withstand greater lateral forces, thereby making the reliability of the vehicle body mount 100 better. At the same time, by disposing the motor primary 34 in the cavity 202, the outer cylinder 21 of the mount cylinder 20 can play a good protective role for the motor primary 34, enabling the motor primary 34 to maintain a good operating state, thereby improving the operating stability of the vehicle body mount 100 when performing active vibration reduction or raising the height of the vehicle body 200.

[0068] In one embodiment of the present invention, referring to Figure 6 and Figure 7As shown, the primary 34 of the motor can be a coil, and a wire groove 201 is formed on the outer circumference of the inner cylinder 22. The coil is arranged in the wire groove 201. A wire hole is formed on the inner cylinder 22. The connection terminal of the coil passes through the wire hole and extends out of the cavity 202. The suspension cylinder 20 also includes an isolation sleeve 33. The isolation sleeve 33 is sleeved on the outer circumference of the inner cylinder 22 to separate the wire groove 201 and the cavity 202.

[0069] In this embodiment, a wire groove 201 is provided on the outer circumference of the inner cylinder 22 to facilitate the positioning and fixing of the coil, while making the assembly of the coil and the inner cylinder 22 more compact, so that the motor primary 34 can be well arranged between the inner cylinder 22 and the outer cylinder 21, avoiding interference between the motor primary 34 and the inner circumference of the outer cylinder 21, so that the motor primary 34 has a good operating environment, and to a certain extent improves the stability of the vehicle body suspension 100.

[0070] The coil is embedded and fixed in the wire groove 201 formed on the outer circumference of the inner cylinder 22, making the motor primary 34 and the inner cylinder 22 more compact, occupying less additional space, thereby making the overall structure of the vehicle body mount 100 more compact and facilitating the installation of the vehicle body mount 100 in the vehicle 1000. In this embodiment, the wire hole formed in the inner cylinder 22 facilitates the connection of the coil in the motor primary 34, making the assembly of the vehicle body mount 100 more convenient. Of course, the outer cylinder can also be formed with a wire hole, and the coil wire can be connected through the wire hole and out of the outer cylinder for connection, which makes the coil connection more flexible and convenient.

[0071] In this embodiment, an isolation sleeve 33 is provided on the outside of the inner tube 22. The isolation sleeve 33 can separate the wire groove 201 from the cavity 202, thereby isolating the oil in the cavity 202 from the coil, so that the motor primary 34 has a good operating environment, making the body suspension 100 more stable when in use. At the same time, the oil in the cavity 202 can have a good heat dissipation effect on the heat generated by the motor primary 34, so that the working environment temperature of the body suspension 100 is maintained in a good state, thereby making the operation stability of the body suspension 100 better.

[0072] Furthermore, the coil can be fixed in the wire slot 201 by a sealant, which can make the coil more firmly fixed in the wire slot 201 and make it easier to fix the coil and the wire slot 201 when assembled. Of course, other materials can also be injected into the wire slot 201 for fixing, which will not be listed here.

[0073] In some examples of the present invention, reference Figure 2 As shown, an oil return channel may be connected between the cavity 202 and the accommodating chamber 203 , and a control valve for controlling the opening and closing of the oil return channel is provided on the oil return channel.

[0074] Thus, by providing an oil return passage between the cavity 202 and the receiving cavity 203, the oil in the receiving cavity 203 can flow into the cavity 202 through the oil return passage, enabling the cavity 202 to store oil. When the vehicle mount 100 actively adjusts the damping, the linear motor structure operates, and part or all of the oil in the receiving cavity 203 can flow into the cavity 202 along the return passage. As a result, when the motor primary 34 and the motor secondary 35 move relative to each other, the resistance of the oil in the receiving cavity 203 to the movement of the piston 40 in the receiving cavity 203 can be reduced, making the active adjustment of the vehicle mount 100 more convenient and rapid.

[0075] Specifically, when the vehicle mount 100 operates with both oil and the linear motor structure, when the piston 40 moves downward under the action of the bumps and vibrations of the vehicle 1000, the oil can inhibit the downward movement of the piston 40 by passing through the flow holes, and the linear motor can cooperate with the oil to actively control the upward movement of the movable rod 10 to inhibit the downward movement of the piston 40, thereby jointly performing the buffering and vibration damping operation; when the linear motor structure in the vehicle mount 100 is powered off or fails, the linear motor structure does not work, and the oil in the receiving cavity 203 can perform passive vibration damping operation, which makes the operation of the vehicle mount 100 more stable and reliable; when the linear motor structure in the vehicle mount 100 operates, after the oil in the receiving cavity 203 is emptied, the linear motor structure can perform active vibration damping operation. This can enable the vehicle mount 100 to always maintain a good vibration damping and buffering effect during the driving process of the vehicle 1000, thereby making the operation of the vehicle 1000 more stable.

[0076] Furthermore, the linear motor structure can set the operation time and operating power according to the vehicle load size, so that under the premise of meeting the requirements of vibration damping and isolation of the vehicle body 200 and the smooth operation of the vehicle 1000, the linear motor structure can have lower power consumption, thereby reducing the use cost of the vehicle mount 100 and improving the economy of the use of the vehicle mount 100.

[0077] It can be understood that with reference to Figure 10 As shown, after the input current of the linear motor structure is disconnected, the relative movement between the motor primary 34 and the motor secondary 35 can generate current, and the current can be converted into electrical energy and stored in the energy storage unit such as the battery or capacitor of the vehicle 1000. During the driving process of the vehicle 1000, when there are bumps and vibrations, the motor primary 34 and the motor secondary 35 will move relative to each other following the suspension cylinder 20 and the movable rod 10, so that the energy generated by the vibration of the vehicle 1000 can be converted into electrical energy for storage, enabling the endurance of the vehicle 1000 to be improved to a certain extent. Specifically, with reference to Figure 10As shown, the electric energy generated by the linear motor structure can be transmitted to the energy storage unit through the energy storage circuit. The energy storage circuit can be electrically connected to the terminals of the coil of the motor primary 34. Among them, the energy storage unit can also be used as an energy supply unit, and the energy storage circuit can also be used as an energy supply circuit.

[0078] In some embodiments of the present invention, referring to Figure 2 As shown, the body mount 100 may further include an oil storage member. The oil storage member is communicated with the accommodating cavity 203 through an oil pipe, and a control valve is connected in series on the oil pipe. This facilitates the active damping adjustment of the vehicle 1000 by the body mount 100, making the body mount 100 respond faster to the bumps and vibrations of the vehicle 1000 during use. Setting an oil pipe and connecting a control valve in series between the oil storage member and the accommodating cavity 203 can more flexibly and conveniently control the flow of oil between the accommodating cavity 203 and the oil storage member, which is beneficial to improving the effect of active vibration reduction of the body mount 100 to a certain extent. Preferably, the oil storage member is an oil storage tank.

[0079] In some embodiments of the present invention, as Figure 2 shown, the motor secondary 35 can be embedded in the movable rod 10.

[0080] Thus, embedding the motor secondary 35 in the movable rod 10 can make the assembly of the motor secondary 35 and the movable rod 10 more compact, and the overall volume of the motor secondary 35 and the movable rod 10 smaller, so that the overall structure of the body mount 100 is more compact and it is more convenient to install and arrange the body mount 100 in the vehicle 1000. For example, the motor secondary 35 can be embedded on the outer peripheral surface of the movable rod 10, and the motor secondary 35 can also be embedded in the movable rod 10.

[0081] In an embodiment of the present invention, as Figure 4 shown, the movable rod 10 may include: a central rod 11 and a sleeve rod 12. The sleeve rod 12 is sleeved outside the central rod 11, and both ends of the sleeve rod 12 are hermetically connected to the central rod 11. The motor secondary 35 is arranged between the sleeve rod 12 and the central rod 11.

[0082] Thus, by arranging the motor secondary 35 between the central rod 11 and the sleeve rod 12, the sleeve rod 12 can play a good role in sealing and isolating oil for the motor secondary 35, enabling the motor secondary 35 to have a good operating environment, and thus making the body mount 100 operate more stably.

[0083] In some examples of the present invention, referring to Figure 4 and Figure 5 shown, an embedding groove 101 may be formed on the outer peripheral surface of the central rod 11, and the motor secondary 35 is fixed in the embedding groove 101. The motor secondary 35 is a permanent magnet.

[0084] A groove 101 is formed on the outer peripheral surface of the central rod 11, and the secondary motor 35 is fixed in the groove 101.

[0089] In this embodiment, the first linear bearing 32 is disposed on the movable rod 10 and / or the seal 31. That is to say, the first linear bearing 32 can be disposed on the movable rod 10, or the first linear bearing 32 can be disposed on the seal 31, or the first linear bearing 32 can be disposed on both the movable rod 10 and the seal 31. By disposing the first linear bearing 32 on the movable rod 10 and / or the seal 31, the resistance when the movable rod 10 reciprocates along the length direction of the suspension cylinder 20 can be reduced, so that the movement of the movable rod 10 is smoother, wear is reduced, and to a certain extent, the service life of the vehicle body mount 100 can be extended. The first linear bearing 32 can play a good guiding role in the movement of the movable rod 10, making the operation of the movable rod 10 more reliable during use, and thus making the vehicle body mount 100 operate more stably.

[0090] In some examples of the present invention, referring to Figure 8 and Figure 9 as shown, a recessed groove can be provided on the inner wall surface of the seal 31. The groove extends along the length direction of the movable rod 10. The number of grooves is multiple, and the multiple grooves are arranged at intervals along the circumferential direction of the seal 31. The first linear bearing 32 can include a cage 321 and balls 322. The cage 321 is annular, and a plurality of balls 322 are provided on the cage 321. The plurality of balls 322 are arranged at intervals along the circumferential direction of the cage 321. Among them, the number of linear bearings corresponds to the grooves one by one. The cage 321 is disposed on the seal 31, and a part of the cage 321 is located in the corresponding groove and extends along the length direction of the groove. The cage 321 is movable along the length direction of the groove, and the balls 322 are in contact with the inner wall of the groove. Thus, by disposing the first linear bearing 32 on the seal 31, the structure is compact and the arrangement is convenient.

[0091] In some examples of the present invention, referring to Figure 2 as shown, the vehicle body mount 100 can further include: a second linear bearing. The vehicle body mount 100 further includes a piston 40. The piston 40 is fixedly connected to one end of the movable rod 10. The piston 40 is disposed in the accommodation cavity 203 and is slidably engaged with the suspension cylinder 20. The second linear bearing is disposed on the piston 40 and / or the suspension cylinder 20, and the piston 40 and the suspension cylinder 20 are slidably engaged through the second linear bearing.

[0092] In this embodiment, the second linear bearing is disposed on the piston 40 and / or the suspension cylinder 20. That is to say, the second linear bearing can be disposed on the piston 40, or the second linear bearing can be disposed on the suspension cylinder 20, or the second linear bearing can be disposed on both the piston 40 and the suspension cylinder 20. The structure of the second linear bearing can be the same as that of the first linear bearing 32 or different from that of the first linear bearing 32.

[0093] For example, referring to Figure 2As shown, when the second linear bearing is arranged on the piston 40, a plurality of recessed grooves can be formed on the outer wall surface on the radially outer side of the piston 40. The second linear bearing is provided with a cage, and a plurality of balls can be provided on the cage. The balls are arranged in one-to-one correspondence with the plurality of grooves, and the cage can be arranged on the piston 40. In this way, when the piston 40 and the inner cylinder 22 move relative to each other, they can be slidably matched through the second linear bearing.

[0094] In this embodiment, by providing the second linear bearing on the piston 40 and / or the suspension cylinder 20, the resistance can be relatively small when the piston 40 slides along the wall surface of the accommodation cavity 203 in the accommodation cavity 203, and the movement is smoother. Especially after the oil in the accommodation cavity 203 is completely emptied, when the piston 40 reciprocates in the accommodation cavity 203, the second linear bearing can greatly reduce the friction between the piston 40 and the wall surface of the accommodation cavity 203 when the piston 40 moves, so that the piston 40 can always move smoothly under different working conditions of the vehicle body suspension 100, reduce the wear between the piston 40 and the suspension cylinder 20, and can extend the service life of the piston 40 and the suspension cylinder 20 to a certain extent.

[0095] In some examples of the present invention, as Figure 2 shown, the vehicle body suspension 100 may further include: a first connecting member 50 and a second connecting member 60.

[0096] Thus, by setting the first connecting member 50 to be connected to the movable rod 10 and connecting the movable rod 10 to the vehicle body 200, the structure is simple, and the connection is fixed, stable and reliable. Optionally, the first connecting member 50 and one of the vehicle body 200 or the vehicle frame 300 can be fixedly connected by a plurality of bolts. Referring to Figure 2 shown, bolts can be fixed on the first connecting member 50, and the screw rods of the bolts extend in the up-and-down direction away from the vehicle body suspension 100. The first connecting member 50 is tightly connected to the vehicle body 200 or the vehicle frame 300 by setting nuts at the corresponding connection positions on the vehicle body 200 or the vehicle frame 300. A plurality of fixing holes can also be provided on the first connection for the screw rods of the bolts to pass through and be connected and fixed to the vehicle body 200 or the vehicle frame 300 by nuts. Optionally, the first connecting member 50 and the movable rod 10 can be connected by threads. Preferably, the first connecting member 50 can be connected to the vehicle body 200.

[0097] In this embodiment, a second connecting member 60 is provided and fixedly connected to the suspension cylinder 20, and the second connecting member 60 is connected to the other of the vehicle frame 300 and the vehicle body 200. The second connecting member 60 and the suspension cylinder 20 can be fixedly connected by fasteners, or the second connecting member 60 can be integrally formed with or welded to the suspension cylinder 20. When the first connecting member 50 is fixedly connected to the vehicle body 200, the second connecting member 60 can be fixedly connected to the vehicle frame 300.

[0098] In a specific embodiment of the present invention, as Figure 2 shown, the second connecting member 60 can be formed in a plate shape, and connection holes for connecting the vehicle body 200 or the vehicle frame 300 are formed on the second connecting member 60. There are a plurality of connection holes, and the plurality of connection holes are arranged at intervals around the suspension cylinder 20.

[0099] In this embodiment, setting the second connecting member 60 in a plate shape can facilitate the connection and fixation with the vehicle body 200 or the vehicle frame 300 in the up and down direction (such as the up and down direction shown in Figure 1 ), and can better support and carry the load in the up and down direction, making the connection and fixation between the vehicle body 200 and the vehicle frame 300 through the body mount 100 more stable and reliable. Connection holes are formed on the second connecting member 60, which can facilitate the connection and fixation with the vehicle body 200 or the vehicle frame 300, making the assembly of the body mount 100 with the vehicle body 200 and the vehicle frame 300 more convenient and easy.

For example, the connection holes can be provided with three, four, five, six, etc.

[0100] Furthermore, as Figure 2 shown, one end of the suspension cylinder 20 facing the second connecting member 60 can be open, and the second connecting member 60 covers the open end of the suspension cylinder 20. Thus, by covering the open end of the suspension cylinder 20 with the second connecting member 60, the structure is simple, and the sealing of the suspension cylinder 20 is more convenient and reliable.
