Description

Technical Field

[0001] This utility model relates to an alarm, and more particularly to an alarm alarm that can prevent the generation of warning messages. Background Technology

[0002] In the normal operation of an electronic control system, there is usually a check mechanism that generates warning information when a fault or abnormality occurs. Taking a vehicle's electronic control system as an example, when the electronic exhaust valve or electronic shock absorber malfunctions or is removed, causing a communication line interruption, the Electronic Control Unit (ECU) will determine that the vehicle's hardware is abnormal. This can range from keeping the malfunction indicator light constantly on to 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] 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 the one in patent application CN303840367S, which claims to be able to shield malfunction warning lights. However, the shielded connector described 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 electronic devices or electronic shock absorbers, and because the circuit parameters of different car manufacturers vary, there will still be situations where they cannot be matched, thus failing to effectively shield malfunction warning lights. Utility Model Content

[0006] The purpose of this invention is to provide an anomaly eliminator that is easy to install and can effectively prevent the generation of warning messages.

[0007] The anomaly eliminator of this invention is applicable to control systems. The control system determines whether the circuit state parameters are compatible with valid values ​​based on the returned electrical signals. If not, it outputs a warning message. The anomaly eliminator includes a shell unit, a coil unit, and a wire unit.

[0008] The shell unit includes a carrier that defines the chamber.

[0009] The coil unit is disposed in the cavity and includes a non-magnetic but conductive core and a conductive coil. The core has an axial section through which the conductive coil passes and a radial section connected to one end of the axial section. The conductive coil is used to output an electrical signal corresponding to the circuit state parameters adapted to the effective value.

[0010] The wire unit is electrically connected to the conductive coil and the control system for transmitting the electrical signal.

[0011] The anomaly eliminater of this utility model has a radial segment that extends radially from the axial segment along the conductive coil and is located on the path of the magnetic field lines generated by the conductive coil.

[0012] The fault eliminator of this utility model has a conductive coil with 50 to 1000 turns and a wire diameter of 0.1 mm to 2 mm.

[0013] The anomaly eliminator of this utility model further includes an insulating material that fills the space between the conductive coil and the carrier and, together with the carrier, encapsulates the core material and the conductive coil.

[0014] The present invention discloses an anomaly eliminator, wherein the carrier has an open end, the coil unit is inserted into the chamber through the open end along an axis, the axial segment of the core material extends along the axis, and the radial segment extends radially from the axial segment along the axis and is blocked between the insulating material and the conductive coil.

[0015] The abnormality eliminater of this utility model has a radial section that is disc-shaped.

[0016] The anomaly eliminater of this utility model has a carrier that has a wiring end opposite to the opening end, and an interface adjacent to the wiring end that connects the chamber to the outside, through which the wire unit passes.

[0017] The present invention discloses an anomaly eliminator, wherein the coil unit further includes a non-magnetic and non-conductive wire frame, the wire frame having a kit that defines a shaft hole around an axis, and two rings connected to opposite ends of the kit, the rings being spaced apart along the axis and defining a wire groove with the kit opening towards the periphery, the axial segment of the core material passing through the shaft hole along the axis, and the radial segment abutting against one of the rings, the conductive coil being wound around the outer peripheral surface of the kit and passing through the wire groove.

[0018] In the anomaly eliminator of this invention, another ring member of the wire frame abuts against the carrier and is adjacent to the wire unit.

[0019] The fault eliminator of this invention has circuit state parameters configured as current value, voltage value, reactance value, or a combination thereof.

[0020] The beneficial effect of this invention is that, using a T-shaped, non-magnetic but conductive core material, the radial segment interferes with the magnetic field during the conversion of electrical and magnetic energy, causing a change in inductive reactance. This simulates the electrical signals transmitted by electronic devices, preventing the triggering of warning messages after the removal of the electronic device. Attached Figure Description

[0021] Other features and effects of this utility model will be clearly presented in the embodiments with reference to the accompanying drawings, wherein:

[0022] Figure 1 This is a perspective view illustrating an embodiment of the anomaly eliminater of this utility model;

[0023] Figure 2 This is a cross-sectional view of the embodiment described;

[0024] Figure 3 This is a block diagram showing the electrical connection of the embodiment to the control system. Detailed Implementation

[0025] See Figure 1 , Figure 2 and Figure 3 One embodiment of the anomaly eliminator of this utility model applies to a control system 11. The control system 11 determines whether the 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, it controls an alarm device (e.g., an alarm light 13) to output an alarm message M. The circuit state parameters are configured as current values, voltage values, reactance values, or combinations thereof. The alarm message M is configured as text, sound, or light.

[0026] Taking the application of the control system 11 to a vehicle (not shown) as an example, the control system 11 determines the status of the electronic device 12 (such as an electronic shock absorber) based on the circuit status parameters (such as reactance value). If the reactance value is within the normal range, the control system 11 determines that the electronic device 12 is working normally. If the reactance value is abnormal, the control system 11 further analyzes the cause of the abnormality and illuminates the warning light 13 electrically connected to the control system 11 to prompt the driver to check and repair it.

[0027] The anomaly eliminator comprises a shell unit 2, a coil unit 3, and a wire unit 4.

[0028] The shell unit 2 includes a carrier 21, which defines a chamber 20.

[0029] The carrier 21 has an open end 211, a wiring end 212 opposite to the open end 211, and an interface 213 adjacent to the wiring end 212 and communicating the chamber 20 with the outside.

[0030] The coil unit 3 is inserted into the cavity 20 through the opening end 211 along an axis X. The coil unit 3 includes a non-magnetic and non-conductive wire frame 31, a non-magnetic but conductive core material 32, a conductive coil 33, and an insulating material 34.

[0031] The wire frame 31 may be made of plastic steel or other non-conductive materials, and has a kit 311 that surrounds the axis X and defines a shaft hole 310, and two rings 312 connected to opposite ends of the kit 311. The rings 312 are spaced apart along the axis X and, together with the kit 311, define a wire groove 313 with an opening facing the periphery. One ring 312 faces the opening end 211. The other ring 312 abuts against the wire routing end 212.

[0032] The core material 32 has an axial segment 321 that passes through the shaft hole 310 along the axis X, and a radial segment 322 connected to one end of the axial segment 321. In this embodiment, the axial segment 321 extends along the axis X. The radial segment 322 extends radially from the axial segment 321 along the axis X and is disk-shaped. The radial segment 322 abuts against a corresponding ring 312. The radial segment 322 is located near one end of the conductive coil 33 along the axis X, and the axis X passes through the center of the radial segment 322. The core material 32 can be made of aluminum, aluminum alloy, or non-magnetic stainless steel (such as Worsfield stainless steel). In this embodiment, the core material 32 has a generally T-shaped cross-section along the axis X and is made of aluminum. With the above arrangement, the radial segment 322 is located on the path of the magnetic field lines generated by the conductive coil 33 and in the region where the magnetic field lines are most concentrated. Thus, when the conductive coil 33 generates a magnetic field, the radial segment 322 is subjected to the magnetic field and induces a corresponding eddy current.

[0033] The conductive coil 33 is wound around the outer peripheral surface of the kit 311 and passes through the wire groove 313. The conductive coil 33 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 33 is spaced apart from the carrier 21 and is blocked by the radial segment 322 of the core material 32. In this embodiment, the number of turns of the conductive coil 33 is between 50 and 1000, and the wire diameter is between 0.1 mm and 2 mm.

[0034] In this embodiment, the insulating material 34 is an epoxy resin, which fills the space between the conductive coil 33 and the carrier 21, and together with the carrier 21 encapsulates the wire frame 31, the core material 32, and the conductive coil 33. This allows the radial segment 322 to be blocked between the insulating material 34 and the conductive coil 33.

[0035] The wire unit 4 is electrically connected to the conductive coil 33 and the control system 11 for transmitting the electrical signal S. The wire unit 4 passes through the interface 213 and is adjacent to the corresponding ring 312 and the wiring end 212.

[0036] When the vehicle is modified and the electronic device 12 needs to be removed, the anomaly eliminator of this invention is used to replace the electronic device 12. In use, simply connect the wiring unit 4 to the control system 11, and then the control system 11 obtains the circuit status parameters through the electrical signal S (e.g., current or voltage) returned by the anomaly eliminator of this invention.

[0037] The principle of the anomaly eliminator of this utility model is as follows: when the control system 11 detects the state of the anomaly eliminator, the anomaly eliminator will generate an electrical signal S similar to or the same as the electronic device 12 being replaced by the conductive coil 33 through the inductance and reactance (or in conjunction with the radial section 322 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.

[0038] Further explanation is as follows:

[0039] When current I flows into the conductive coil 33 from one end and flows out from the other end, the inductance L and inductive reactance X generated by the conductive coil 33 are... L The formula is as follows:

[0040] L=NΦ B / I…………Formula(1)

[0041] X L =2πfL…………Formula (2)

[0042] 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).

[0043] 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 33, and the magnetic flux Φ. B It is related to the size.

[0044] Furthermore, formula (2) further illustrates that the inductive resistance X L It is directly proportional to the inductance L.

[0045] In other words, it affects the inductive X L The main factor is the inductance L of the conductive coil 33, which depends on the number of turns N, dimensions (e.g., wire diameter and length), material of the core 32, 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.

[0046] This invention uses a non-magnetic but conductive core material 32, which can avoid the nonlinear saturation effect common in magnetic materials, thereby reducing signal distortion. Furthermore, it reduces the heat generated by hysteresis loss, resulting in better temperature stability.

[0047] More importantly, the T-shaped design of the core material 32 (forming the radial segment 322 at one end of the axial segment 321) allows eddy currents to be generated when a changing magnetic field is produced by a current I (typically a DC power supply) passing through the conductive coil 33. This change in magnetic field is induced by the conductive but non-magnetic radial segment 322, thus forming 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 33. L The value of X. That is, while maintaining the original voltage withstand design dimensions of the coil unit 3, the inductive reactance X can be further reduced. L The value of the electrical signal S returned to the control system 11 is adjusted so that it is more compatible with the effective value of the replaced electronic device 12, thereby improving the matching degree and stability.

[0048] 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 33. L To conform to the effective value of the replaced electronic device 12.

[0049] Based on the above explanation, the advantages of the aforementioned embodiments can be summarized as follows:

[0050] 1. By simply connecting this utility model to the control system 11, the electronic device 12 can be replaced, thus avoiding the generation of the warning message M. Not only is the technical threshold for installation low, but the installation is also simple; even ordinary car owners or mechanics can complete the installation.

[0051] 2. This utility model uses a T-shaped, non-magnetic but conductive core material 32, which can sense changes in the magnetic field through the radial segment 322 when the conductive coil 33 generates a changing magnetic field, thereby adjusting the magnetic field and making 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 electronic device 12.

[0052] 3. Furthermore, this invention can also block the conductive coil 33 through the radial section 322 of the core material 32, the wire frame 31, and the insulating material 34, thereby increasing the area of ​​isolation and insulation, and preventing interference from other external components to the conductive coil 33. For example, when other conductive components (not shown) or other conductive lines (not shown) exist around the anomaly eliminator of this invention, the radial section 322 of the core material 32, the wire frame 31, and the insulating material 34 can block the conductive coil 33, preventing the conductive coil 33 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.

[0053] 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.
