Description

Technical Field

[0001] This application relates to the field of vehicle testing technology, and in particular to a vehicle ignition lock circuit testing device. Background Technology

[0002] Currently, my country has a large number of vehicles, with internal combustion engine vehicles accounting for a significant proportion. For some of these vehicles, starting the engine still requires placing the mechanical key in the ST position (start position) of the ignition lock. However, during the starting process, the starter motor is prone to malfunctions, affecting the normal use of the vehicle and requiring rapid diagnosis and troubleshooting to restore the vehicle to normal working condition as quickly as possible. Due to limitations in the vehicle's ignition lock circuitry, when diagnosing and troubleshooting other types of vehicle faults, it is sometimes necessary to switch the vehicle key position to inspect and diagnose a specific circuit or component.

[0003] In related technologies, because some components and wiring in the starting circuit are located far from the ignition lock, when there is only one repairman at the scene of a vehicle malfunction, the repairman cannot simultaneously turn the key and check the wiring or components. Therefore, it is impossible to quickly and efficiently diagnose and troubleshoot starter motor malfunctions, thus reducing vehicle repair efficiency. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] In related technologies, some vehicles still require the mechanical key to be placed in the ST position (start position) of the ignition lock to start the engine. Under normal circumstances, when the key is in the ST position, the current flow of the starting circuit is as follows: from the positive terminal of the battery, through the main fuse, the ST position of the ignition lock, the ignition lock fuse, the starter relay coil terminal to ground; another current flows from the positive terminal of the battery through the starter relay switch terminal to the starter motor control terminal, so that the starter motor can operate and complete the vehicle starting action.

[0024] When starting a vehicle with a mechanical key, the starter motor may fail to operate, affecting the vehicle's normal use. In special situations or during emergency tasks, a starter motor malfunction requires rapid diagnosis and troubleshooting to restore the vehicle to normal working condition as quickly as possible. Due to limitations in the vehicle's ignition lock circuitry, repair personnel may sometimes need to switch the vehicle key position to inspect and diagnose specific circuits or components when troubleshooting other types of vehicle faults.

[0025] There are two main scenarios when diagnosing and troubleshooting vehicle malfunctions. One scenario involves having two or more repair personnel on-site. In this case, it is relatively easier to diagnose and troubleshoot a starter motor malfunction. Specifically, one person places the key in the ST position, while the other person uses a test pen or multimeter to check each circuit component and line through which the current flows in the starting circuit, following the direction of the current, until the fault point is found, which is located between the point where there is current and the point where there is no current. It is important to note that the key should not be turned to the ST position for too long during the troubleshooting process to prevent the starter motor from burning out. Another scenario is when there is only one repairman on site. Because some components and wiring in the starting circuit are located far from the ignition lock, the same repairman cannot perform the action of checking the wiring or components while turning the key. Therefore, it is impossible to quickly and efficiently carry out the work of diagnosing and troubleshooting starter motor faults, thus reducing vehicle repair efficiency.

[0026] In view of this, this application provides a vehicle ignition lock circuit detection device, including a fixing unit, comprising a support structure 200 and a limiting structure 300 interconnected; the support structure 200 abuts against the driver's seat of the vehicle, and the limiting structure 300 abuts against the steering wheel 100 of the vehicle, so as to limit the rotation of the steering wheel 100 by the limiting structure 300; the operating unit includes a mounting platform 400, a drive structure 500 and a clamping structure 600; the mounting platform 400 is fixedly connected to the steering wheel 100, the drive structure 500 is disposed on the mounting platform 400, and the clamping structure 600 is fixedly connected to the output end of the drive structure 500 for clamping the mechanical key of the vehicle, so that the drive structure 500 drives the mechanical key to rotate through the clamping structure 600.

[0027] See Figures 1-4 This application provides a vehicle ignition lock circuit testing device, which is suitable for a single repairman to troubleshoot and diagnose faults in the vehicle's ignition lock circuit. It assists the repairman in switching the key position of the faulty vehicle to efficiently and quickly diagnose and troubleshoot starter motor faults, thereby improving vehicle repair efficiency. The testing device includes a fixing unit for limiting the rotation of the vehicle's steering wheel 100, and an operating unit disposed on the steering wheel 100 for rotating the key position of the faulty vehicle.

[0028] The fixing unit includes a support structure 200 and a limiting structure 300. One end of the support structure 200 rests against the driver's seat of the vehicle, and the other end is connected to the limiting structure 300 to support and provide pressure to the limiting structure 300. The limiting structure 300 rests against the steering wheel 100 and, under the action of the support structure 200, can apply pressure to the steering wheel 100 to restrict the rotation of the steering wheel 100, thereby fixing the steering wheel 100 and providing a stable and reliable working platform for the operating unit so that the operating unit can stably drive the mechanical key to rotate and switch.

[0029] The operating unit includes a mounting platform 400, a drive structure 500, and a clamping structure 600. The mounting platform 400 is fixedly connected to the steering wheel 100 and provides a mounting position for the drive structure 500. The drive structure 500 is mounted on the mounting platform 400, and its output end is connected to the clamping structure 600 to provide drive torque to the clamping structure 600 holding the mechanical key, thereby driving the mechanical key to rotate. Specifically, when the drive structure 500 is running, it drives the clamping structure 600 connected to its output end to rotate, causing the clamping structure 600 to synchronously rotate the mechanical key inserted in the ignition lock position, achieving automatic gear switching and realizing automated adjustment of the key gear.

[0030] In some embodiments, the support structure 200 includes a base 210, an angle adjustment component 220, and a support rod 230; one side of the base 210 abuts against the driver's seat, the angle adjustment component 220 is disposed on the other side of the base 210 and is connected to the end of the support rod 230 through the angle adjustment component 220, and the support rod 230 is connected to the limiting structure 300.

[0031] See Figure 1 and Figure 2 The support structure 200 supports the limiting structure 300 and applies pressure to it, causing the limiting structure 300 to act on the steering wheel 100 to prevent the steering wheel 100 from rotating. The support structure 200 includes a base 210, an angle adjustment component 220, and a support rod 230. One side of the base 210 rests against the driver's seat, ensuring sufficient contact area between the support structure 200 and the base 210 to improve support stability. The support rod 230 is connected to the base 210 via the angle adjustment component 220 and is used to support the limiting structure 300. Furthermore, to accommodate various angles within the driver's cab, the angle adjustment component 220 can adjust the angle between the support rod 230 and the base 210, ensuring that the limiting structure 300 can apply a relatively stable positive pressure to the steering wheel 100, thus improving the limiting effect on the steering wheel 100.

[0032] In some embodiments, the angle adjustment component 220 includes a connecting protrusion 221 and a bolt fastener 222; the connecting protrusion 221 protrudes from the side of the base 210, and the bolt fastener 222 passes through the ends of the connecting protrusion 221 and the support rod 230 respectively, for locking or unlocking the connecting protrusion 221 and the support rod 230.

[0033] See Figure 1 and Figure 2 The angle adjustment component 220 can be used to adjust the angle between the support rod 230 and the base 210, making it adaptable to the multi-angle usage needs in the driver's cab and improving the fixation effect on the steering wheel 100. The angle adjustment component 220 includes a connecting protrusion 221 and a bolt fastener 222. The connecting protrusion 221 is disposed on the base 210, and the bolt fastener 222 passes through the ends of the connecting protrusion 221 and the support rod 230, respectively. When adjusting the angle between the support rod 230 and the base 210, the bolt fastener 222 is loosened, releasing the connection between the bolt fastener 222 and the support rod 230. The locking effect between the protrusion 221 and the support rod 230 is achieved by rotating the support rod 230 along the bolt fastener 222, changing the angle between the base 210 and the support rod 230, so that the support rod 230 can apply stable pressure to the steering wheel 100 through the limiting structure 300, thus restricting the rotation of the steering wheel 100. After adjustment, the bolt fastener 222 is tightened again, so that the two connecting protrusions 221 press against the support rod 230, thereby relocking the support rod 230 and the connecting protrusions 221, restricting the deflection between them, and ensuring the fixing effect of the steering wheel 100.

[0034] In some embodiments, the support structure 200 further includes a fixing ring 240 and a spring 250; the fixing ring 240 is fixedly disposed on the support rod 230, and the spring 250 is sleeved on the support rod 230 in cooperation with it, with the two ends of the spring 250 abutting against the fixing ring 240 and the limiting structure 300 respectively.

[0035] See Figure 1 and Figure 2When the detection device is in use, the support structure 200 in the fixed unit applies pressure to the steering wheel 100 through the limiting structure 300, thereby restricting the rotation of the steering wheel 100. The support structure 200 also includes a fixing ring 240 and a spring 250, which can be a compression spring. The limiting structure 300 is pressed against the steering wheel 100. Since the limiting structure 300 is slidably connected to the support rod 230, the limiting structure 300 slides along the support rod 230 toward the base 210, applying pressure to the spring 250 and shortening it. Since the spring 250 has elastic restoring force, it can apply a reverse thrust to the limiting structure 300, so that the limiting structure 300 is firmly pressed against the steering wheel 100. The steering wheel 100 will not rotate under the pressure, forming a relatively stable operating platform and providing a relatively stable operating position for the operating unit.

[0036] It should be noted that, in order to prevent the limiting structure 300 from detaching from the support rod 230, an anti-detachment component (not shown in the figure) can be provided at the end of the support rod 230, such as an anti-detachment bolt or anti-detachment pin, to prevent the limiting structure 300 from detaching from the support rod 230 under the action of the spring force of the spring 250, and to ensure that the detection device has good integrity.

[0037] In some embodiments, the limiting structure 300 includes an arc-shaped bracket 310, a limiting rod 320, a limiting cap 330, and a grip 340; the arc-shaped bracket 310 is slidably connected to the support rod 230 and abuts against the end of the spring 250; two limiting rods 320 are provided, the two limiting rods 320 are provided on the same side of the arc-shaped bracket 310 and abut against the steering wheel 100; the limiting cap 330 is provided at the end of the limiting rod 320 away from the arc-shaped bracket 310; and the grip 340 is provided on the side of the arc-shaped bracket 310 away from the limiting rod 320.

[0038] See Figure 1 and Figure 2Under the action of the support structure 200, the limiting structure 300 abuts against the steering wheel 100 and applies pressure to the steering wheel 100, restricting the rotation of the steering wheel 100. The limiting structure 300 includes an arc-shaped bracket 310, a limiting rod 320, a limiting cap 330, and a grip 340. The arc-shaped bracket 310 is slidably connected to the support rod 230, providing installation positions for the limiting rod 320 and the grip 340. The limiting rod 320 and the grip 340 are respectively located on opposite sides of the arc-shaped bracket 310. There are two limiting rods 320. When the steering wheel 100 abuts against the limiting rod 320, it is subjected to the force of the spring 250. Due to the elastic restoring force, the limiting rod 320 can apply pressure to the steering wheel 100. Since the contact area between the steering wheel 100 and the limiting rod 320 is small, the pressure acting on the steering wheel 100 is more obvious, so the limiting effect is relatively good. A limiting cap 330 is provided at the end of the limiting rod 320 away from the arc bracket 310 to prevent the steering wheel 100 from detaching from the limiting rod 320 and ensure the firmness of the steering wheel 100. In addition, a grip 340 is provided on the side of the arc bracket 310 away from the limiting rod 320, which makes it convenient for maintenance personnel to install the fixing unit and reduces the difficulty of fixing the steering wheel 100.

[0039] In some embodiments, the mounting platform 400 includes a protective shell 410 and a strap 420; the protective shell 410 is fixedly connected to the strap 420, and the drive structure 500 is disposed inside the protective shell 410 and is bound to the steering wheel 100 by the strap 420.

[0040] See Figure 1 and Figure 3 After the fixing unit is assembled, the fixing unit restricts the rotation of the steering wheel 100, so that the steering wheel 100 can form a relatively stable operating platform. The mounting platform 400 in the operating unit is fixedly connected to the steering wheel 100, which can provide an operating position for the drive structure 500, so that the drive structure 500 can drive the mechanical key to stably switch key positions through the clamping structure 600. The mounting platform 400 includes a protective shell 410 and a strap 420. The protective shell 410 can provide an installation position for the drive structure 500 and can protect the drive structure 500. At the same time, by setting the strap 420 on the protective shell 410, it can adapt to the arc structure of the steering wheel 100, thereby firmly fixing the protective shell 410 to the steering wheel 100 and improving the installation firmness of the protective shell 410.

[0041] In addition, multiple through holes can be evenly arranged on the protective shell 410. Since the drive structure 500 generates a lot of heat when it is working, by setting multiple through holes on the protective shell 410, the heat generated by the drive unit can be dissipated to the outside through the through holes, so as to avoid heat accumulation and affect the normal operation of the drive structure 500.

[0042] In some embodiments, the drive structure 500 includes a motor 510, a reducer 520, a control module 530, and a power interface 540. The motor 510, reducer 520, and control module 530 are all disposed inside the protective housing 410. The motor 510 is connected to the reducer 520 in a transmission manner. The output end of the reducer 520 is fixedly connected to the clamping structure 600. The power interface 540 is disposed in the protective housing 410 and is electrically connected to the motor 510 and the control module 530, respectively. The control module 530 is electrically connected to the motor 510.

[0043] See Figure 1 and Figure 3 After the operating unit is fixed to the steering wheel 100, the mechanical key is clamped by the clamping structure 600. Then, the drive structure 500 drives the mechanical key to rotate through the clamping structure 600 to switch the key position. The drive structure 500 includes a motor 510, a control module 530, and a power interface 540. The power interface 540 can be connected to an external power source, the vehicle's cigarette lighter, or the vehicle's battery through a connecting harness to supply power to the motor 510 and the control module 530. Specifically, when the drive structure 500 is started, the control module 530 controls the motor 510 to rotate, and the motor 510 provides driving force. After the motor 510 rotates, it drives the reducer 520 connected to its output end to rotate synchronously. The reducer 520 reduces the output speed of the motor 510 and increases the output torque, so that the drive structure 500 drives the clamping structure 600 to rotate. Then, the clamping structure 600 drives the mechanical key to rotate and switch the key position at the ignition lock position.

[0044] It should be noted that the main function of the control module 530 mentioned above is to control the operation of the drive motor 510 and drive the mechanical key to rotate synchronously, thereby switching the key position at the ignition lock position. The control module 530 can also work with a remote control to control the drive structure 500. Specifically, a position sensor (not shown in the figure) can be installed inside the protective housing 410 to collect the rotor position information of the motor 510 in real time and send this information to the control module 530. The control module 530 then determines the current key position and sends it to the remote control so that the user is aware of the current key position. At this time, maintenance personnel can send a rotation command to the control module 530 via the remote control. After receiving the rotation command, the control module 530 controls the motor 510 to rotate through a preset program, and drives the clamping structure 600 to rotate by a corresponding preset angle through the reducer 520, causing the clamping structure 600 to switch the mechanical key to the corresponding position. The control module 530 can be a microcontroller, which is low-cost and stable in operation, and will not be elaborated further here.

[0045] In addition, to help operators clearly understand the current gear position of the mechanical key, the remote control can be equipped with multiple LED indicators, each corresponding to a preset gear position; for example, when the mechanical key is in any of the ON, ACC, or ST positions, the corresponding LED indicator on the remote control will be lit.

[0046] In some embodiments, the clamping structure 600 includes a universal joint assembly 610 and a key clamp 620; one end of the universal joint assembly 610 is fixedly connected to the output end of the reducer 520, and the key clamp 620 is fixedly connected to the other end of the universal joint assembly 610.

[0047] See Figure 1 and Figure 4 In this embodiment, the mechanical key is rotated by the operating unit to switch the key position of the ignition lock. The clamping structure 600 in the operating unit includes a universal joint assembly 610 and a key clamp 620. The universal joint assembly 610 is connected to the output end of the drive structure 500 and the key clamp 620. When the drive structure 500 rotates, it can drive the universal joint assembly 610 to rotate synchronously, which is used to transmit the torque output by the drive structure 500. The universal joint assembly 610 changes the direction and angle of torque transmission and transmits it to the key clamp 620. The key clamp 620 is used to fix and clamp the mechanical key at the ignition lock position. When the key clamp 620 receives the transmitted torque, it will transmit the torque to the mechanical key to drive the mechanical key to switch the key position.

[0048] It should be noted that, due to the good splicing ability of the universal joint assembly 610, when the distance between the mounting platform 400 and the ignition lock is long or the angle deviation is large, multiple universal joints can be connected in sequence to meet the distance and angle requirements between the drive structure 500 and the ignition lock, so as to drive the mechanical key to rotate.

[0049] In addition, since different vehicle models have different mechanical key specifications for starting the vehicle, various types of key clamps 620 can be equipped to hold different types of mechanical keys, so as to make reasonable selection according to different mechanical keys, ensure the firmness of the key clamp 620 in holding the mechanical key, and ensure the rotation effect of the mechanical key.

[0050] In some embodiments, the key clamp 620 includes an elastic part 621 and a clamping part 622; the elastic part 621 is connected to the universal joint assembly 610 by bolts, and two clamping parts 622 are provided, which are respectively fixedly connected to the two ends of the elastic part 621, so that a clamping space for clamping the mechanical key is formed between the two clamping parts 622.

[0051] See Figure 4The mechanical key is clamped and fixed using a key clamp 620. Driven by the drive structure 500, the mechanical key is rotated through the key clamp 620, thereby switching the key position at the ignition lock position. The key clamp 620 includes an elastic part 621 and a clamping part. The elastic part 621 is connected to the universal joint assembly 610 by bolts, which facilitates the replacement of the key clamp 620 and the clamping and fixing of the mechanical key. Two clamping parts 622 are provided, and the two clamping parts 622 are respectively connected to the two ends of the elastic part 621. Under the action of the elastic force of the elastic part 621, the two clamping parts 622 can move closer or further away from each other, changing the size of the clamping space to achieve the clamping effect on the mechanical key.

[0052] Based on the same inventive concept, this application also provides a storage box 700 for accommodating the ignition lock circuit detection device of the vehicle in any of the above embodiments; wherein, the storage box 700 includes a box body 710, a box cover 720 and a locking buckle 730; the box body 710 and the box cover 720 are rotatably connected, the interior of the box body 710 is used to accommodate the detection device, and the locking buckle 730 is disposed on the box cover 720 for locking or unlocking the box body 710 and the box cover 720.

[0053] See Figure 5 This application also provides a storage box 700 for loading and storing the ignition lock circuit testing device for the aforementioned vehicle, facilitating carrying and transportation, and also protecting the testing device. The storage box 700 includes a box body 710, a lid 720, and a locking buckle 730. The box body 710 holds the testing device, the lid 720 closes and seals the box body 710, and the locking buckle 730 locks the box body 710 and lid 720 together to prevent the lid 720 from accidentally opening and causing the testing device to slide out of the box body 710. For example, the locking buckle 730 can be a push-button type. Furthermore, to improve the protection of the testing device, foam layers are provided on the inner walls of the box body 710 and the lid 720, which can act as cushioning and improve the protection of the testing device.
