Description

Technical Field

[0001] This disclosure relates to the field of solenoid valve technology, and more specifically, to a bracket assembly, a solenoid valve, a shock absorber, and a vehicle. Background Technology

[0002] Shock absorbers in vehicles are used to prevent excessive spring oscillation, thus achieving a damping effect. Widely used in automobiles, their working principle is that when the vehicle body vibrates, the piston inside the shock absorber moves up and down, causing the damping fluid within the shock absorber to flow repeatedly between different chambers through a pre-set passage. This generates damping force, converting the energy of the vehicle's vibration into fluid heat energy, which is then absorbed by the shock absorber and dissipated into the atmosphere. Shock absorbers typically also include solenoid valves, which adjust the path of the damping fluid (such as adjusting the flow area of ​​the passage), thereby regulating the damping force of the shock absorber.

[0003] The solenoid valve of a vibration damper typically includes a support assembly and a coil wound around the support assembly. When the coil is energized, it can make the valve core extending into the support assembly magnetic. In related technologies, such solenoid valves have problems such as difficulty in assembling the support assembly and large fluctuations in the magnetic force of the coil. How to solve the above problems is the research direction of this field. Utility Model Content

[0046] With the above technical solution, the coil can be wound around the outside of the bracket body, and the coil's inlet and outlet wires can be threaded through the lead wire structure. Since the lead wire structure is arranged separately from the bracket body, such as when the lead wire structure can be suspended relative to the bracket body, the coil's inlet and outlet wires can be threaded through the lead wire structure, allowing the coil's inlet and outlet wires to be led out to a suitable position through the lead wire structure. For example, the lead wire structure can be set at the position directly opposite the opening of the piston rod of the shock absorber, thereby facilitating the leading out of the coil's inlet and outlet wires into the piston rod.

Therefore, the lead wire structure can be well supported, and the first connector and the second connector can have good structural stability. On the one hand, it is beneficial to avoid deformation of the first connector and the second connector during processing and storage, so that the bracket assembly can be easier to assemble. On the other hand, it is beneficial to avoid deformation of the first connecting beam and the second connecting beam caused by the operation of the solenoid valve and the damper, and to avoid deformation of the bracket body caused by the first connecting beam and the second connecting beam. For example, it is beneficial to avoid deformation of the position where the coil is wound on the bracket body, so as to avoid local displacement of the coil, thereby reducing the magnetic fluctuation of the coil and improving the consistency of the damping force of the damper using the bracket assembly.

[0048] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0059] 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.

[0060] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "top," and "bottom" are generally defined according to the direction shown on the drawing (see reference for details). Figure 5 (As shown), it is only for the convenience of describing this disclosure and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as a limitation of this disclosure. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. In addition, the terms "first," "second," etc., are used to distinguish one element from another and do not have any order or importance.

[0061] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0062] In related technologies, a solenoid valve typically includes a support assembly, a wire wound around the support assembly, and a valve core passing through the support assembly. The wire wound around the support assembly can form a coil, and when the coil is energized, it can make the valve core passing through the solenoid valve magnetic.

[0063] Research has found that, in related technologies, the problems of difficult assembly of the support assembly and large fluctuations in the magnetic force of the coil in the solenoid valve of the shock absorber are at least partly due to the limitations imposed by the installation position of the solenoid valve within the shock absorber and the structure of the shock absorber. This prevents the inlet and outlet wires of the coil wound on the support assembly from being directly led out from their winding position. Therefore, a single cantilever is usually formed on the support assembly of the solenoid valve to support the lead wire structure of the support assembly in a suitable position, so that the inlet and outlet wires can be led out to a suitable position through the lead wire structure. For example, the lead wire structure can be supported at the axial end of the support assembly, so that the inlet and outlet wires can be led out to the piston rod of the solenoid valve through the lead wire structure.

[0064] However, single cantilever arms have poor structural stability due to the lack of support at one end, making them prone to deformation during processing and storage, which can lead to assembly difficulties. During the use of solenoid valves, the operation of the solenoid valve and the vibration damper can also cause deformation of the single cantilever arm. This deformation can also cause deformation of other parts of the support assembly (such as the area where the coil is wound), resulting in local displacement of the coil and thus large fluctuations in the coil's magnetic force.

[0065] In view of this, such as Figures 1 to 7As shown, this disclosure provides a support assembly 100, including a support body 10, a lead wire structure 30, a first connector 23, and a second connector 24. The support body 10 is used for winding a coil 300. The lead wire structure 30 is arranged separately from the support body 10 and is used for passing the inlet wire 301 and outlet wire 302 of the coil 300. The first end of the first connector 23 and the first end of the second connector 24 are respectively connected to the support body 10, and the second end of the first connector 23 and the second end of the second connector 24 are both connected to the lead wire structure 30.

[0066] Through the above technical solution, the coil 300 can be wound around the outside of the bracket body 10, and the inlet wire 301 and outlet wire 302 of the coil 300 can be passed through the lead wire structure 30. Since the lead wire structure 30 is arranged separately from the bracket body 10, such as the lead wire structure 30 being suspended relative to the bracket body 10, the inlet wire 301 and outlet wire 302 of the coil 300 can be passed through the lead wire structure 30, so that the inlet wire 301 and outlet wire 302 of the coil 300 can be led out to a suitable position through the lead wire structure 30. For example, the lead wire structure 30 can be set at the position opposite to the opening of the piston rod 2001 of the shock absorber, so as to facilitate the lead wire 301 and outlet wire 302 of the coil 300 to be led out into the piston rod 2001.

[0067] Furthermore, compared with the bracket assembly in the related technology that supports the lead wire structure with a single cantilever, the first end of the first connector 23 and the first end of the second connector 24 of the bracket assembly 100 provided in this application are respectively connected to the bracket body 10, and the second ends of the first connector 23 and the second connector 24 are both connected to the lead wire structure 30. Therefore, the lead wire structure 30 can be well supported, and the first connector 23 and the second connector 24 can both have good structural stability. On the one hand, this helps to avoid damage to the first connector 23 and the second connector 24 during processing and storage. The deformation makes the bracket assembly 100 easier to assemble. On the other hand, it helps to avoid deformation of the first connecting beam and the second connecting beam caused by the operation of the solenoid valve 1000 and the damper 2000, and also helps to avoid deformation of the bracket body 10 caused by the first connecting beam and the second connecting beam. For example, it helps to avoid deformation of the position where the coil 300 is wound on the bracket body 10, thereby helping to avoid local displacement of the coil 300, which in turn helps to reduce the magnetic fluctuation of the coil 300 and improve the consistency of the damping force of the damper 2000 using the bracket assembly 100.

[0068] In addition, the inlet wire 301 and outlet wire 302 of the coil 300 can be arranged on the first connector 23 and the second connector 24 respectively, which helps to reduce the risk of short circuit between the inlet wire 301 and outlet wire 302 of the coil 300, thereby improving the reliability and safety of the solenoid valve 1000.

[0069] It is understood that the inlet wire 301 and outlet wire 302 of coil 300 can be arranged in different connectors, such as the inlet wire 301 and outlet wire 302 being arranged in the first connector 23 and the second connector 24 respectively, or they can be arranged in the same connector. This disclosure does not limit this.

[0070] Optionally, the support assembly 100 may be made of an insulating material to have good insulation properties; for example, the support assembly 100 may be made of plastic.

[0071] This disclosure does not limit the connection position of the first connector 23 and the second connector 24 on the support body 10. As one embodiment, such as Figure 5 As shown, the first end of the first connector 23 and the first end of the second connector 24 are respectively connected to different positions on the support body 10. This arrangement helps to avoid local stress concentration on the support body 10 and improves the stability of the support structure jointly constructed by the first connector 23 and the second connector 24, thereby reducing the risk of deformation of the support body 10, the first connector 23, and the second connector 24.

[0072] In other embodiments of this disclosure, the first end of the first connector 23 and the first end of the second connector 24 may also be connected to adjacent positions on the bracket body 10.

[0073] In this disclosure, as one implementation method, such as Figure 5 As shown, the support body 10 is an annular component, with the first end of the first connector 23 and the first end of the second connector 24 connected to different positions on the circumference of the support body 10. The annular design of the support body 10 facilitates the winding of the coil 300 around its outer circumference and allows the valve core 200 to extend into it. Furthermore, the connection of the first end of the first connector 23 and the first end of the second connector 24 to different positions on the circumference of the support body 10 helps to avoid localized stress concentration in the support body 10.

[0074] It is understood that the annular structure of the support body 10 can be constructed from a continuous structure, such as a cylinder, or it can be enclosed by multiple structures, such as multiple individual components arranged in annular intervals. As long as the area enclosed by its inner circumference can be used for the valve core 200 to pass through, and its outer circumference can be used for the coil 300 to be wound, this disclosure does not limit it.

[0075] Optionally, such as Figure 5As shown, the first end of the first connector 23 and the first end of the second connector 24 are arranged at equal intervals along the circumference of the support body 10. This arrangement helps to distribute the forces acting on the annular component in the circumference and allows the first connector 23 and the second connector 24 to be constructed as an arched structure, thereby improving the structural stability of the first connector 23 and the second connector 24, preventing deformation of both, and preventing the lead wire structure 30 from swaying relative to the support body 10.

[0076] In this disclosure, the lead structure 30 can be set at any suitable position according to actual needs. This disclosure does not limit this. As one implementation method, such as Figure 5 As shown, along the axial direction of the support body 10, the projection of the lead wire structure 30 is located in the middle of the projection of the support body 10. This arrangement facilitates the lead wire 301 and lead wire 302 of the coil 300 to be led out from one end of the axial direction of the support body 10, especially when the support body 10 and the piston rod 2001 of the damper 2000 are coaxially arranged, making it convenient for the lead wire 301 and lead wire 302 of the coil 300 to be led out into the piston rod 2001.

[0077] As another embodiment of this disclosure, along the axial direction of the support body 10, the projection of the lead structure 30 may be located outside the projection of the support body 10.

[0078] In this disclosure, the first end of the first connector 23 and the first end of the second connector 24 can be connected to any position along the axial direction of the support body 10. This disclosure does not limit this. As one embodiment, such as Figure 5 As shown, the first end of the first connector 23 and the first end of the second connector 24 are both connected to one end of the bracket body 10 in the axial direction.

[0079] Compared to the first end of the first connector 23 and the first end of the second connector 24 being connected to different positions along the axial direction of the bracket body 10, the first end of the first connector 23 and the first end of the second connector 24 being connected to one end along the axial direction of the bracket body 10 is beneficial for the first connector 23 and the second connector 24 to obtain closer structural stability, and is also beneficial for saving space and facilitating the installation of other structures of the solenoid valve 1000. For example, it is convenient to set the valve core 200 of the solenoid valve 1000 inside the bracket body 10.

[0080] This disclosure does not limit the construction of the first connector 23 and the second connector 24. As one embodiment, such as Figure 5 As shown, along the axial direction of the support body 10, the second end of the second connector 24 is closer to the support body 10 than the second end of the first connector 23.

[0081] This design allows for good differentiation between the first connector 23 and the second connector 24, thus preventing incorrect installation of other structures during assembly. For example, it helps prevent the inlet wire 301 and outlet wire 302 of the coil 300 from being installed in reverse.

[0082] Optionally, such as Figure 4 and Figure 5 As shown, at least one of the first connector 23 and the second connector 24 is used to lay the inlet wire 301 and / or the outlet wire 302 of the coil 300. That is, the inlet wire 301 and the outlet wire 302 of the coil 300 can be laid to the lead wire structure 30 through at least one of the first connector 23 and the second connector 24, which helps to avoid the inlet wire 301 and the outlet wire 302 of the coil 300 from shaking, and further helps to avoid the inlet wire 301 and the outlet wire 302 of the coil 300 from breaking, wearing, etc.

[0083] To facilitate the arrangement of the inlet wire 301 and / or outlet wire 302 of the coil 300 on the first connector 23 and the second connector 24, as one embodiment, such as Figure 5 As shown, the first connector 23 is provided with a first wiring groove 251, which extends from the first end of the first connector 23 to the second end of the first connector 23. The second connector 24 is provided with a second wiring groove 252, which extends from the first end of the second connector 24 to the second end of the second connector 24.

[0084] The inlet wire 301 and outlet wire 302 of the coil 300 are arranged through the first wiring groove 251 and the second wiring groove 252. On the one hand, this can protect the inlet wire 301 and outlet wire 302 of the coil 300, which helps to prevent the inlet wire 301 and outlet wire 302 of the coil 300 from being rubbed or squeezed, and also helps to prevent the inlet wire 301 and outlet wire 302 of the coil 300 from contacting the metal parts and causing insulation failure. On the other hand, the wiring groove can fix the inlet wire 301 and outlet wire 302 of the coil 300, which helps to prevent the inlet wire 301 and outlet wire 302 of the coil 300 from being displaced due to shaking.

[0085] As another embodiment of this disclosure, the inlet wire 301 and outlet wire 302 of the coil 300 can also be tied to the first connector 23 and / or the second connector 24 by means of a binding material (such as insulating tape).

[0086] To ensure the reliability of the coil 300's mounting on the bracket body 10, as one implementation method, such as... Figure 5As shown, the support body 10 is an annular component. A winding groove 12 is provided on the outer side of the support body 10 to accommodate a coil 300 wound on the support body 10. The support body 10 has a first notch 131 and a second notch 132 with different structures. A first wiring groove 251 communicates with the winding groove 12 through the first notch 131, and a second wiring groove 252 communicates with the winding groove 12 through the second notch 132. The coil 300 can be wound within the winding groove 12, which can limit the movement of the coil 300, helping to prevent the coil 300 from detaching from the axial component along the axial direction of the support body 10.

[0087] Since the first wiring groove 251 is connected to the winding groove 12 through the first notch 131, and the second wiring groove 252 is connected to the winding groove 12 through the second notch 132, the first notch 131 and the second notch 132 can avoid the incoming wire 301 and the outgoing wire 302 of the coil 300, which helps to reduce the laying length of the incoming wire 301 and the outgoing wire 302 of the coil 300, and helps to avoid the incoming wire 301 and the outgoing wire 302 of the coil 300 from being damaged by excessive bending.

[0088] Furthermore, since the first notch 131 and the second notch 132 have different structures, that is, the first notch 131 and the second notch 132 can have different shapes or different sizes, it is beneficial to improve the distinguishability of the first notch 131 and the second notch 132, which can play a role in preventing mistakes during the assembly process, and thus help to avoid the incorrect connection of the inlet wire 301 and the outlet wire 302 of the coil 300.

[0089] This disclosure does not limit the construction of the first notch 131 and the second notch 132. As one embodiment, such as Figure 5 As shown, the first notch 131 connects to the side wall of the first wiring groove 251, and / or the second notch 132 connects to the bottom wall of the second wiring groove 252. This arrangement facilitates the adaptation of the first notch 131 and the second notch 132 to the routing of the inlet wire 301 and outlet wire 302 of the coil 300 at corresponding positions, and further reduces the bending of the inlet wire 301 and outlet wire 302 of the coil 300.

[0090] Optionally, such as Figures 2 to 6 As shown, the bracket assembly 100 also includes an insulating cover 400, which includes a first sealing portion 411 and a second sealing portion 412. The first sealing portion 411 covers the opening of the first wiring groove 251, and the second sealing portion 412 covers the opening of the second wiring groove 252.

[0091] By sealing the opening of the first wiring groove 251 with the first cover part 411 and the opening of the second wiring groove 252 with the second cover part 412, the wires (such as the inlet wire 301 and the outlet wire 302) can be well fixed in the first wiring groove 251 and / or the second wiring groove 252, which helps to prevent the wires from shaking. On the other hand, it helps to prevent the wires in the first wiring groove 251 and / or the second wiring groove 252 from coming into contact with other metal parts (such as the magnetic cover plate 500) through the opening of the corresponding wiring groove, which would lead to insulation failure.

[0092] Here, the insulating cover 400 can be made of insulating material, or it can be made of plastic.

[0093] This disclosure does not limit the construction of the first sealing portion 411 and the second sealing portion 412. As one embodiment, such as Figures 2 to 6 As shown, along the axial direction of the support body 10, the second cover portion 412 is closer to the support body 10 than the first cover portion 411. This arrangement facilitates the fitting of the first cover portion 411 and the second cover portion 412 with the first connector 23 and the second connector 24, which have different structures.

[0094] For example, in an embodiment where the second end of the second connector 24 is closer to the support body 10 than the second end of the first connector 23 along the axial direction of the support body 10, the insulating cover 400 constructed above can effectively cover the first wiring groove 251 through the first cover portion 411 and can effectively cover the second wiring groove 252 through the second cover portion 412.

[0095] Optionally, such as Figures 2 to 6 As shown, an insulating cover 400 is provided with a sleeve 420, which is sleeved on the outside of the lead wire structure 30. The first sealing part 411 and the second sealing part 412 are both connected to the sleeve 420. This arrangement facilitates the simultaneous installation of the first sealing part 411 and the second sealing part 412, which helps to improve the installation efficiency of the insulating cover 400 and the installation accuracy of the first sealing part 411 and the second sealing part 412.

[0096] Optionally, such as Figure 5 and 6 As shown, the bracket body 10 is provided with a first snap-fit ​​part 15, and the insulating cover 400 is provided with a second snap-fit ​​part 430, which snaps into the first snap-fit ​​part 15.

[0097] The snap-fitting of the second snap-fitting part 430 with the first snap-fitting part 15 improves the connection reliability between the insulating cover 400 and the bracket assembly 100. It also prevents the first sealing part 411 and the second sealing part 412 from easily disengaging from their sealing positions. Furthermore, the snap-fitting mechanism facilitates easy disassembly and replacement of components, such as the insulating cover 400 and the bracket body 10.

[0098] This disclosure does not limit the construction of the first latching portion 15 and the second latching portion 430. As one embodiment, such as Figure 5 and Figure 6 As shown, the first latching part 15 includes one of a latching block and a latching groove disposed on the bracket body 10, and the second latching part 430 includes the other of a latching block and a latching groove disposed on the insulating cover 400, with the latching block latched in the latching groove. The latching block and latching groove have a simple structure and high structural reliability, are easy to manufacture, and help ensure the reliability of the connection between the insulating cover 400 and the coil 300.

[0099] In another embodiment, the first snap-fit ​​portion 15 and the second snap-fit ​​portion 430 can be a snap hook and a snap ring, respectively.

[0100] Optionally, such as Figure 3 and 7 As shown, the bracket assembly 100 also includes a magnetic cover plate 500, which is disposed at one end of the bracket body 10 along the axial direction. The magnetic cover plate 500 is used to transmit the magnetic lines of force generated when the coil 300 is energized to the valve core 200. The magnetic cover plate 500 is provided with a through groove 530 that extends through the magnetic cover plate 500 along the axial direction of the bracket body 10. At least a portion of the first connector 23 is accommodated in the through groove 530. And / or, the end of the magnetic cover plate 500 near the bracket body 10 is provided with a receiving groove 520 that is recessed in the direction away from the bracket body 10. At least a portion of the second connector 24 is accommodated in the receiving groove 520.

[0101] By accommodating at least a portion of the first connector 23 within the through groove 530 and at least a portion of the second connector 24 within the receiving groove 520, it is beneficial to reduce the space occupied by the bracket assembly 100 and improve space utilization.

[0102] Furthermore, since the receiving groove 520 does not penetrate the magnetic cover plate 500, the combination of the through groove 530 and the receiving groove 520 can ensure that the magnetic cover plate 500 is well positioned between the magnetic cover plate 500 and the bracket body 10, and make the magnetic cover plate 500 a single piece, which helps to reduce the manufacturing cost and installation difficulty of the magnetic valve cover.

[0103] It should be noted that the magnetic permeability of the magnetic cover plate 500 can be greater than that of air. As a result, the magnetic lines of force generated by the energized wire are attenuated less on the path to the valve core 200, allowing the magnetic lines of force of the wire to act more effectively on the valve core 200, increasing the magnetic field strength of the valve core 200, and making the magnetic force between the valve core 200 and other magnetic material parts of the solenoid valve 1000 greater. While ensuring the magnetic field strength of the valve core 200, the amount of copper in the wire can be reduced to lower production costs.

[0104] Optionally, such as Figure 3 and 7 As shown, the magnetic cover plate 500 is provided with a through hole 510 that extends through the magnetic cover plate 500 along the axial direction of the bracket body 10. The lead wire structure 30 passes through the through hole 510, and the through hole 510 is connected to the receiving groove 520 and / or the through groove 530.

[0105] The lead wire structure 30 passes through the through hole 510, which facilitates the positioning between the bracket body 10 and the magnetic conductive assembly and improves the assembly efficiency between the two. Furthermore, the connection between the receiving groove 520 and the through hole 510 allows the wires laid on the second connector 24 to easily enter through the through hole 510 and pass through the magnetic conductive cover plate 500. Similarly, the connection between the through groove 530 and the through hole 510 allows the wires laid on the first connector 23 to easily enter through the through hole 510 and pass through the magnetic conductive cover plate 500.

[0106] Optionally, such as Figure 2 , 3 As shown in Figure 7, the magnetic cover plate 500 is provided with a clearance portion 540, which is located at one end of the receiving groove 520 near the through hole 510. The clearance portion 540 can avoid the structure of the solenoid valve 1000 near the through hole 510, for example, it can avoid the part where the second connector 24 is connected to the lead wire structure 30, thereby improving space utilization and reducing the space occupied by the bracket assembly 100.

[0107] This disclosure does not limit the structure of the clearance portion 540. As one embodiment, the clearance portion 540 includes a clearance hole that penetrates the magnetic cover plate 500 along its axial direction. The clearance hole can provide a large degree of clearance for other structures and is easy to manufacture.

[0108] As another implementation method, such as Figure 7 As shown, the clearance portion 540 can be the groove wall of the receiving groove 520 near the through hole 510, which is farther away from the bracket body 10 than the groove wall in other locations.

[0109] According to a second aspect of this disclosure, a solenoid valve 1000 is provided, including a coil 300, an inlet wire 301, an outlet wire 302, and the aforementioned support assembly 100. The coil 300 is wound around the outer periphery of the support body 10. The two ends of the inlet wire 301 are respectively used to connect the beginning of the coil 300 and the positive terminal of the power supply. The two ends of the outlet wire 302 are respectively used to connect the end of the coil 300 and the negative terminal of the power supply. Both the inlet wire 301 and the outlet wire 302 are passed through the lead wire structure 30.

[0110] The solenoid valve 1000 may also include a valve core 200, and a receiving cavity 11 is provided in the bracket body 10, with at least a portion of the valve core 200 extending into the receiving cavity 11.

[0111] It is understandable that the power supply here refers to the power supply that supplies power to the coil 300. When the two ends of the inlet wire 301 are connected to the beginning of the coil 300 and the positive terminal of the power supply respectively, and the two ends of the outlet wire 302 are connected to the end of the coil 300 and the negative terminal of the power supply respectively, the power supply can generate current flowing sequentially through the inlet wire 301, the coil 300 wound on the bracket body 10, and the outlet wire 302, so that the coil 300 generates a magnetic field acting on the valve core 200.

[0112] Optionally, such as Figure 4 As shown, the incoming line 301 is arranged on the first connector 23, and the outgoing line 302 is arranged on the second connector 24. This arrangement helps to improve the insulation between the incoming line 301 and the outgoing line 302 of the coil 300, and helps to avoid insulation failure between them.

[0113] According to a third aspect of this disclosure, a vibration damper 2000 is provided, such as Figure 1 As shown, it includes the aforementioned solenoid valve 1000.

[0114] According to a fourth aspect of this disclosure, a vehicle is provided, including the aforementioned shock absorber 2000.

[0115] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0116] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0117] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
