Description

Technical Field

[0001] This utility model relates to an electronic shock absorber, and more particularly to an electronic shock absorber that can eliminate abnormalities and avoid generating warning messages. Background Technology

[0002] In the normal operation of a vehicle's electronic control system, there is usually a check mechanism that generates warning information when a fault or abnormality occurs. For example, when an electronic shock absorber malfunctions or is removed, causing a communication line interruption, the Electronic Control Unit (ECU) will determine that the vehicle hardware is abnormal, which may result in the warning light remaining constantly on or, in more serious cases, locking the engine power.

[0003] Therefore, when modifying electronic equipment or electronic shock absorbers, it is necessary to process the bypass signal to prevent the signal from floating and causing the fault light to remain constantly on. Currently, the main way to solve the problem of a constantly on fault light is to use a scanner to read and clear the fault codes.

[0004] However, clearing or rewriting fault codes requires a high level of technical skill, which is beyond the capabilities of most car owners or mechanics. Furthermore, since the root cause of the fault remains unresolved, the fault light may illuminate again. This not only affects the driving experience but may also mask the real problem, leading to safety hazards while driving.

[0005] There is another type of shielded connector on the market, such as patent number CN303840367S, which claims to be able to shield malfunction warning lights. However, the shielded connector is configured as a conductor, at most used only for transmitting electrical signals. Due to significant differences in circuit parameters such as current, voltage, and resistance between the connector and the electronic shock absorber, and because the circuit parameters of different car manufacturers vary, there will still be mismatches, resulting in the inability to effectively shield the malfunction warning lights.

It also includes a movable isolator that can move along the axis and passes through the main chamber space and the expansion space, allowing the main chamber space and the expansion space to change their relative volumes. The piston unit is movable along the axis and passes through the main chamber space.

[0020] This invention discloses an electronic shock absorber capable of eliminating abnormalities. The piston unit includes a piston in airtight contact with the chamber unit, a piston rod sleeve passing through the piston along the axis and inserted outside the chamber unit, and a control valve movable along the axis and inserted through the piston rod sleeve. The piston divides the main cavity space to form two variable-volume chambers and establishes a first flow path connecting the chambers. The piston rod sleeve has an outer ring portion defining a perforation and an inner ring portion inserted within the perforation and defining a valve port. The piston rod sleeve also establishes a second flow path connecting the chambers and including the perforation and the valve port. The control valve is operablely inserted within the perforation of the piston rod sleeve and has a conical section defining an annular gap with the inner ring portion of the piston rod sleeve, and a rod section opposite to the conical section and screwed into the outer ring portion. The annular gap is part of the second flow path for the passage of damping fluid, which flows between the chambers.

[0021] The present invention relates to an electronic shock absorber capable of eliminating abnormalities. The chamber unit includes a first cylindrical member surrounding the axis and an end cap. The end cap is connected to one end of the first cylindrical member and, together with the first cylindrical member and the movable isolator, defines the main cavity space. The carrier unit is connected to the other end of the first cylindrical member and, together with the first cylindrical member and the movable isolator, defines the expansion space, such that the main cavity space and the expansion space are arranged sequentially along the axis.

[0022] The present invention discloses an electronic shock absorber capable of eliminating abnormalities. The chamber unit includes a first cylindrical member surrounding the axis and defining the main chamber space, and a second cylindrical member defining the amplification space. A movable isolator is movably inserted into the second cylindrical member along the direction of the axis and separates the amplification space to form a variable-volume expansion chamber that communicates with the main chamber space, and a variable-volume gas chamber that stores gas. The expansion chamber and the gas chamber are arranged along the direction of the axis, and the main chamber space and the amplification space are side by side.

[0023] The present invention provides an electronic shock absorber capable of eliminating abnormalities. The chamber unit further includes an end cap connected to one end of the first cylinder, a plug cap connected to the other end of the first cylinder, and a plug seat connected to one end of the second cylinder.

[0043] See Figure 1 , Figure 2 and Figure 3 A first embodiment of this invention, an electronic shock absorber capable of eliminating abnormalities, is applicable to a control system 11 of a vehicle (not shown). The control system 11 determines whether circuit state parameters are within valid values ​​based on a returned electrical signal S (e.g., current or voltage). If yes, the determination continues; if no, a warning device (e.g., warning light 13) is controlled to output warning information M. The circuit state parameters are configured as current values, voltage values, reactance values, or combinations thereof. The warning information M is configured as text, sound, or light.

[0044] In this embodiment, the control system 11 is applied to a vehicle (not shown) and can determine the status of the original shock absorber 12 based on the circuit status parameters (such as reactance value). If the reactance value is within the normal range, the control system 11 will determine that the original shock absorber 12 is working normally. If the reactance value is abnormal, the control system 11 will further analyze the cause of the abnormality and generate light through a warning light 13 electrically connected to the control system 11 to prompt the driver to check and repair it.

[0045] The electronic shock absorber capable of eliminating abnormalities includes a chamber unit 2, a piston unit 3, a carrier unit 4, a coil unit 5, and a wire unit 6.

[0046] See Figure 3 and Figure 4 The chamber unit 2 includes a first cylindrical member 23 that surrounds an axis X and defines a main cavity space 21 and an expansion space 22, a movable isolation member 24, and an end cap 25 connected to one end of the first cylindrical member 23.

[0047] The main cavity space 21 stores damping fluid.

[0048] In this embodiment, the expansion space 22 stores gas.

[0049] The movable isolator 24 is movable and inserted between the main cavity space 21 and the amplification space 22 along the direction of the axis X, so that the relative volumes of the main cavity space 21 and the amplification space 22 can be changed.

[0050] The end cap 25, together with the movable isolation member 24 and the first cylindrical member 23, defines the main cavity space 21, so that the main cavity space 21 and the expansion space 22 are arranged sequentially along the direction of the axis X.

[0051] The piston unit 3 is movably disposed in the main cavity space 21 through the end cap 25 along the direction of the axis X, and includes a piston 31 that is in airtight contact with the first cylinder 23, a piston rod sleeve 32 that is connected to the piston 31 through the end cap 25 along the direction of the axis X, and a control valve 33 that is movably disposed in the piston rod sleeve 32 along the direction of the axis X.

[0052] The piston 31 divides the main cavity space 21 to form two variable volume chambers 211, and constructs a first flow path L1 that connects the chambers 211 as shown by the solid arrow.

[0053] The plug sleeve 32 has an outer ring portion 322 defining a through hole 321, and an inner ring portion 324 passing through the through hole 321 and defining a first valve port 323. The plug sleeve 32 also constructs a second flow path L2 communicating with the chamber 211 and as shown by the dashed arrow. The second flow path L2 includes the through hole 321 and the first valve port 323.

[0054] In this embodiment, the control valve 33 is operablely inserted into the perforation 321 of the plug rod sleeve 32 and has a tapered section 332 that defines an annular gap 331 with the inner ring portion 324 of the plug rod sleeve 32, and a rod section 333 opposite to the tapered section 332 and screwed into the outer ring portion 322. The annular gap 331 is constructed as part of the second flow path L2 for the passage of damping fluid and for flow between the chambers 211.

[0055] See Figure 2 , Figure 3 and Figure 5 The carrier unit 4 is connected to the other end of the first cylindrical member 23 and includes a carrier 41 with an outward opening and a pair of caps 42 that fit into the carrier 41 and together with the carrier 41 define an installation space 40.

[0056] The carrier 41, together with the first cylindrical member 23 and the movable isolator 24, defines the amplification space 22, such that the main cavity space 21 and the amplification space 22 are arranged sequentially along the direction of the axis X.

[0057] The cover 42 has an interface 421 that connects the installation space 40 to the outside world.

[0058] The coil unit 5 is inserted through the mounting space 40 along the axis X, and includes a non-magnetic and non-conductive wire frame 51, a non-magnetic but conductive core material 52, and a conductive coil 53.

[0059] The wire frame 51 may be made of plastic steel or other non-conductive materials, and has a kit 512 that defines a shaft hole 511 around the axis X, and two rings 513 connected to opposite ends of the kit 512. The rings 513 are spaced apart along the axis X and together with the kit 512 define a wire groove 514 with an opening facing the periphery. One of the rings 513 faces the carrier 41, and the other ring 513 faces the cover 42.

[0060] The core material 52 has an axial segment 522 passing through the shaft hole 511 along the axis X, and a radial segment 521 connected to one end of the axial segment 522. In this embodiment, the axial segment 522 extends along the axis X. The radial segment 521 extends radially from the axial segment 522 along the axis X and is disk-shaped. The radial segment 521 is positioned between the carrier 41 and the conductive coil 53, abutting against the corresponding ring 513 and the carrier 41, and is located near the end of the conductive coil 53 along the axis X. The axis X passes through the center of the radial segment 521. The core material 52 can be made of aluminum, aluminum alloy, or non-magnetic stainless steel (such as Worsfield stainless steel). In this embodiment, the core material 52 has a generally T-shaped cross-section along the axis X and is made of aluminum. With the above arrangement, the radial segment 521 is located on the path of the magnetic field lines generated by the conductive coil 53, and in the region where the magnetic field lines are most concentrated. Thus, when the conductive coil 53 generates a magnetic field, the radial segment 521 is subjected to the magnetic field and induces a corresponding eddy current.

[0061] The conductive coil 53 is wound around the outer peripheral surface of the kit 512 and passes through the wire groove 514. The conductive coil 53 extends along the axis X, and when current flows through it, the changing magnetic field it generates forms corresponding magnetic poles at both ends along the axis X. The conductive coil 53 is spaced apart from the carrier 41 and the cover 42, and is blocked by the radial segment 521 of the core material 52. In this embodiment, the number of turns of the conductive coil 53 is between 50 and 1000, and the wire diameter is between 0.1 mm and 2 mm.

[0062] The wire unit 6 is electrically connected to the conductive coil 53 and the control system 11, and is used to transmit the electrical signal S. The wire unit 6 is located through the interface 421 and adjacent to the corresponding ring 513.

[0063] When a vehicle is modified to replace the original shock absorber 12 with the electronic shock absorber of this invention that can eliminate abnormalities, it is only necessary to electrically connect the wiring unit 6 to the control system 11. Then, the control system 11 obtains the circuit state parameters through the electrical signal S (e.g., current or voltage) returned by the electronic shock absorber of this invention that can eliminate abnormalities.

[0064] The principle of this invention to eliminate abnormalities is that when the control system 11 detects the state of the electronic shock absorber, the electronic shock absorber will generate an electrical signal S similar to or the same as the original shock absorber 12 being replaced through the inductance and reactance formed by the conductive coil 53 (or also in conjunction with the radial section 521 to adjust the magnetic field and stabilize the voltage), and transmit it back to the control system 11 so that the control system 11 can determine that the current circuit state parameters (e.g., the reactance value corresponding to the electrical signal S) are normal.

[0065] Further explanation is as follows:

[0066] When current I flows into the conductive coil 53 from one end and out from the other end, the inductance L and inductive reactance X generated by the conductive coil 53 are... L The formula is as follows:

[0067] L=NΦ B / I…………Formula(1)

[0068] X L =2πfL…………Formula (2)

[0069] Where L is the inductance value, measured in Henry (H), N is the number of turns in the coil, and Φ B X is the magnetic flux per turn, measured in Weber (Wb), I is the current through the coil, measured in Amperes (A), and X... L f is the inductive reactance, measured in ohms (Ω), and f is the frequency (Hz).

[0070] According to formula (1), we can know the magnitude of the inductance L and the current I, the number of turns N of the conductive coil 53, and the magnetic flux Φ. B It is related to the size.

[0071] Furthermore, formula (2) further illustrates that the inductive resistance X L It is proportional to the inductance L.

[0072] In other words, it affects the inductive X L The main factor is the inductance L of the conductive coil 53, which depends on the number of turns N, dimensions (e.g., wire diameter and length), material of the core 52, and overall structural design (e.g., winding method). These factors collectively affect the magnetic flux Φ.B The distribution and intensity of the inductance affect the value L of the inductance.

[0073] This invention uses a non-magnetic but conductive core material 52, which can avoid the nonlinear saturation effect common in magnetic materials, thereby reducing signal distortion. Furthermore, it can reduce the heat generated by hysteresis loss, resulting in better temperature stability.

[0074] More importantly, the T-shaped design of the core material 52 (forming the radial segment 521 at one end of the axial segment 522) allows eddy currents to be generated by the conductive but non-magnetic radial segment 521 when a changing magnetic field is generated by a current I (typically a DC power supply) passing through the conductive coil 53. This induced magnetic field change generates eddy currents, which in turn form magnetic lines of force that resist the change in the original magnetic field. This achieves the adjustment of the magnetic field distribution and the control of the magnetic flux Φ. B The aforementioned X-ray resistance L The effect of the change. Thus, the inductive reactance X can be adjusted without changing the number of turns N and the dimensions of the conductive coil 53. L The value of X. That is, while maintaining the original voltage withstand design dimensions of the coil unit 5, the inductive reactance X can be further reduced. L The value of the signal S is adjusted so that the electrical signal S transmitted back to the control system 11 can be better matched to the effective value of the original shock absorber 12 that has been replaced, thereby improving the matching degree and stability.

[0075] Of course, different values ​​of inductive reactance X can also be generated by appropriately adjusting the wire diameter and number of turns of the conductive coil 53. L To match the effective value of the original shock absorber 12 that was replaced.

[0076] See Figure 2 , Figure 3 and Figure 4 When the piston unit 3 is impacted by the road surface and moves along the axis X during the movement of the vehicle, the damping fluid flows between the chambers 211 through the first flow path L1 and the second flow path L2, and pushes the movable isolation member 24 in the first cylinder 23, so that the gas in the expansion space 22 is compressed or rebounded, thereby achieving the shock absorption effect.

[0077] It is worth noting that the main technical feature of this utility model lies in avoiding triggering the warning information M. The aforementioned principle of using damping fluid and gas for shock absorption is not the focus of this utility model and is existing technology. Since those skilled in the art can deduce the extended details based on the above description, they will not be elaborated further.

[0078] It is worth noting that this invention can also be manually rotated using a hand tool (not shown) to move the control valve 33 along the axis X and change the size of the annular gap 331. Therefore, when the piston unit 3 is impacted by the road surface and moves along the axis X, the damping fluid flowing between the chamber 211 through the first flow path L1 and the second flow path L2 will have its flow velocity changed due to the change in the size of the annular gap 331. This allows for greater variation in the damping stiffness based on the flow velocity of the damping fluid.

[0079] It should be noted that this utility model is not limited to encapsulating the coil unit 5 with the carrier 41 and the cover 42. In other variations of this embodiment, the carrier unit 4 further includes an insulating material 43 that fills the space between the carrier 41 and the coil unit 5 and encapsulates the coil unit 5 together with the carrier 41. The insulating material 43 is an epoxy resin.

[0080] See Figure 7 A second embodiment of the electronic shock absorber capable of eliminating abnormalities, similar to the first embodiment, also includes the chamber unit 2, the piston unit 3, the carrier unit 4, the coil unit 5, and the wire unit 6. The difference lies in:

[0081] The chamber unit 2 also includes a second cylindrical component 26, a plug seat 27, and a tube component 28.

[0082] The first cylindrical member 23 defines the main cavity space 21, and the end away from the end cap 25 is a closed end.

[0083] The second cylindrical component 26 defines the expansion space 22.

[0084] The movable isolator 24 is movably inserted into the second cylindrical member 26 along the X-axis, and separates the amplification space 22 to form a variable-volume expansion chamber 221 that communicates with the main cavity space 21, and a variable-volume gas chamber 222 that stores gas. Thus, the expansion chamber 221 and the gas chamber 222 are arranged along the X-axis, with the main cavity space 21 and the amplification space 22 side-by-side.

[0085] The plug seat 27 is connected to one end of the second cylindrical member 26.

[0086] The pipe fitting 28 connects the expansion chamber 221 and the main cavity space 21. In this embodiment, the pipe fitting 28 is connected to the first cylindrical member 23 and the plug seat 27 by welding or integral forming, so that the pipe fitting 28, the plug seat 27, and the first cylindrical member 23 are fixedly connected to each other to prevent leakage.

[0087] The carrier unit 4 is connected to the other end of the second cylindrical component 26.

[0088] Therefore, the second embodiment can also use a T-shaped, non-magnetic core material 52 to change the inductive reactance during the conversion of electrical energy and magnetic energy, thereby simulating the electrical signal S returned by the original shock absorber 12 and preventing the warning information M from being triggered after the original shock absorber 12 is removed. Furthermore, the expansion chamber 221 can expand the capacity of the damping fluid, allowing the damping fluid to flow not only between the chambers 211 but also between the expansion chamber 221 and the main cavity space 21.

[0089] See Figure 8 and Figure 9 A third embodiment of the electronic shock absorber capable of eliminating abnormalities is similar to the second embodiment, also including the chamber unit 2, the piston unit 3, the carrier unit 4, the coil unit 5, and the wire unit 6. The difference is that the electronic shock absorber capable of eliminating abnormalities also includes a switching unit 7.

[0090] The chamber unit 2 further includes a plug 29. The plug 29 is connected to the end of the first cylindrical member 23 opposite to the end cap 25, and together with the tube 28, the plug seat 27, and the first cylindrical member 23, forms a third flow path L3 for the damping fluid to flow between the expansion chamber 221 and the main cavity space 21. The plug seat 27 has an outer ring 272 defining a shaft cavity 271, and an inner ring 274 passing through the shaft cavity 271 and defining a second valve port 273. In this embodiment, the inner ring 274 extends along the direction of the axis X.

[0091] The switching unit 7 is installed on the plug seat 27 and includes a switch valve 71 that can be operated and moved along the direction of the axis X, a screwed member 72 that is screwed to the switch valve 71, and a rotating member 73 that is rotatably sleeved on the plug seat 27 and can drive the screwed member 72 to rotate.

[0092] The switching valve 71 and the inner ring 274 of the plug seat 27 define a blockable gap 711. The shaft cavity 271, the second valve port 273, and the gap 711 are configured to form part of the third flow path L3. The switching valve 71 is movable relative to the inner ring 274 to open or close the second valve port 273.

[0093] The rotating member 73 is used to drive the screwed member 72 to rotate, so that the switching valve 71 can move relative to the inner ring body 274 along the direction of the axis X.

[0094] Therefore, by simply rotating the rotating member 73, the switching valve 71 can be moved relative to the inner ring 274 along the axis X via the screw connector 72. When the switching valve 71 opens the second valve port 273, the damping fluid can flow bidirectionally between the main cavity space 21 and the expansion chamber 221 through the third flow path L3, as shown by the solid and dashed arrows. When the switching valve 71 closes the second valve port 273, it can block part of the third flow path L3, and the damping fluid can only flow between the expansion chamber 221 and the main cavity space 21 through part of the third flow path L3, as shown by the solid arrow. This changes the speed and damping magnitude of the piston unit 3 during rebound and compression.

[0095] See Figures 10 to 13 A fourth embodiment of the electronic shock absorber capable of eliminating abnormalities is similar to the third embodiment, also including the chamber unit 2, the piston unit 3, the carrier unit 4, the coil unit 5, and the wire unit 6. The difference is that the electronic shock absorber capable of eliminating abnormalities also includes two switching units 7.

[0096] The plug seat 27 defines two shaft cavities 271 and has two inner ring bodies 274. Each inner ring body 274 passes through its respective shaft cavity 271. The plug seat 27 and the end cap 25 connected to the tube 28 form two third flow paths L3. In this embodiment, the inner ring body 274 extends in a direction perpendicular to the axis X.

[0097] The switching valve 71 is movable relative to the inner ring 274 in a direction perpendicular to the axis X. The shaft cavity 271, the second valve port 273, and the gap 711 are configured to form part of the third flow path L3.

[0098] Therefore, by simply turning any of the screw connections 72 with a hand tool, the respective switching valves 71 can be moved toward their respective inner rings 274 in a direction perpendicular to the axis X. When one of the switching valves 71 closes the corresponding second valve port 273, the corresponding third flow path L3 is blocked, allowing the damping fluid to flow bidirectionally between the main cavity space 21 and the expansion chamber 221 through the other third flow path L3, as shown by the solid arrow. When the switching valve 71 closes the second valve port 273, a portion of the third flow path L3 is also blocked. This allows for greater variation in the damping magnitude and the rebound speed of the piston unit 3.

[0099] It should be noted that in the fourth embodiment, the number of the switch unit 7 is not limited to two; in other variations of this embodiment, it may also be one.

[0100] It is worth noting that the components used to construct the first flow path L1, the second flow path L2, or the third flow path L3 have one or more holes or openings for the damping fluid to pass through. Since those skilled in the art can deduce further details from the above description, they will not be elaborated upon further.

[0101] Based on the above explanation, the advantages of the aforementioned embodiments can be summarized as follows:

[0102] 1. By simply connecting this utility model to the control system 11, it can replace the original shock absorber 12 and avoid generating the warning message M. Not only is the installation technically simple and easy, but even ordinary car owners or mechanics can complete the installation.

[0103] 2. The T-shaped, non-magnetic but conductive core material 52 of this invention can sense changes in the magnetic field through the radial segment 521 when the conductive coil 53 generates a changing magnetic field, thereby adjusting the magnetic field and increasing the reactance X as described above. L The effect of the change. Therefore, this invention can adjust the returned electrical signal S to better match the original shock absorber 12.

[0104] 3. Furthermore, this invention can also block the conductive coil 53 through the radial section 521 of the core material 52, the wire frame 51, and the insulating material 43, thereby increasing the area of ​​isolation and insulation, and preventing interference from other external components to the conductive coil 53. For example, when there are other conductive components (not shown) or other conductive lines (not shown) around the electronic shock absorber that can eliminate abnormalities according to this invention, the radial section 521 of the core material 52, the wire frame 51, and the insulating material 43 can block the conductive coil 53, preventing the conductive coil 53 from contacting or being interfered with by the aforementioned other conductive components or other conductive lines. This makes the value of the inductance L and the inductive reactance X... L The value remained stable.

[0105] 4. This utility model can also be used in conjunction with the control valve 33 or the switch unit 7 to change the flow speed of the damping fluid in the chamber 211 or to change the rebound speed of the piston unit 3, so that the damping stiffness has more variability and can meet different usage requirements.

[0106] The above description is merely an embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model shall still fall within the scope of the present utility model.
