Description

Technical Field

[0001] This application relates to the field of vehicle inspection technology, specifically to an upgrade device for a vehicle inspection apparatus and a vehicle inspection apparatus. Background Technology

[0002] Vehicles typically require inspection after a certain number of years of use. Most existing vehicle inspection facilities are equipped with single-axle dynamometers. Single-axle dynamometers are generally used to test two-wheel-drive vehicles, but cannot test four-wheel-drive vehicles. Utility Model Content

[0003] In view of the above problems, this application provides an upgraded device for a vehicle testing apparatus and a vehicle testing apparatus, which can solve the problem that single-axis dynamometers in vehicle testing sites are usually used to test two-wheel drive vehicles but cannot test four-wheel drive vehicles.

[0004] To solve the aforementioned technical problems, this application adopts the following technical solution: An upgrade device for a vehicle testing apparatus is provided, comprising: a support mechanism; a mobile dynamometer disposed on the support mechanism and movable relative to the support mechanism; and a wheelbase adjustment mechanism fixed to the support mechanism and connected to the mobile dynamometer. The wheelbase adjustment mechanism is used to drive the mobile dynamometer to move. The upgrade device includes only one dynamometer, the mobile dynamometer. Through the combined action of the support mechanism, the mobile dynamometer, and the wheelbase adjustment mechanism, the position of the mobile dynamometer can be changed. When the upgrade device is installed near a fixed dynamometer at a vehicle testing site, the mobile dynamometer can move relative to the fixed dynamometer under the action of the wheelbase adjustment mechanism. The fixed dynamometer tests front-wheel drive or rear-wheel drive vehicles, while the mobile dynamometer tests rear-wheel drive or front-wheel drive vehicles. When the upgrade device and the fixed dynamometer at the vehicle testing site work together, all drive types of vehicles can be tested, and the wheelbase range of all drive types of vehicles can be effectively covered.

[0005] In some embodiments, the upgrade equipment for the vehicle testing device further includes a signal interface for communication with a mobile dynamometer; wherein the signal interface is configured to connect to both a diagnostic tool for new energy vehicles and an exhaust gas analyzer for gasoline vehicles. This ability to connect to both diagnostic tools for new energy vehicles and exhaust gas analyzers for gasoline vehicles through the signal interface enables the upgrade equipment to be compatible with vehicles of all drive types.

[0006] In some embodiments, the signal interface is a single interface; or, the signal interface includes a first signal interface and a second signal interface; wherein, the first signal interface is configured to connect to a diagnostic instrument for new energy vehicles, and the second signal interface is configured to connect to an exhaust gas analyzer for gasoline vehicles. Using a single interface can reduce the complexity of upgrading equipment and achieve compatibility between gasoline and new energy vehicles. Alternatively, the first and second signal interfaces can improve the stability of data transmission and achieve compatibility between gasoline and new energy vehicles.

[0007] In some embodiments, the upgraded equipment for the vehicle testing device further includes a diagnostic instrument for new energy vehicles and an exhaust gas analyzer for gasoline vehicles. By limiting the upgraded equipment to include the aforementioned diagnostic instrument and exhaust gas analyzer, testing efficiency can be improved.

[0008] In some embodiments, the diagnostic instrument for new energy vehicles includes an insulation resistance tester; the exhaust gas analyzer for gasoline vehicles includes a five-gas analyzer and / or a smoke meter. Using the aforementioned insulation resistance tester, five-gas analyzer, and smoke meter, corresponding tests can be performed according to the different types of vehicles being tested.

[0009] In some embodiments, the wheelbase adjustment mechanism includes: a driving member; and multiple connecting members spaced apart between the driving member and the mobile dynamometer; each of the multiple connecting members has one end connected to the driving member and the other end connected to the mobile dynamometer. Through the combined action of the driving member, the multiple connecting members, and the mobile dynamometer, the positional change between the mobile dynamometer and the fixed dynamometer can be adjusted. The mechanism has a simple structure and is easy to operate and install.

[0010] In some embodiments, the supporting mechanism includes: a support platform; a wheelbase adjustment mechanism and a movable dynamometer, both disposed on the support platform; and a movable fork tooth disposed on the side of the wheelbase adjustment mechanism opposite to the support platform. By confining the movable fork tooth to a position above the wheelbase adjustment mechanism, the movable fork tooth can provide a certain load-bearing function, thereby improving the overall strength of the upgraded equipment. Furthermore, as the movable dynamometer moves closer to or further away from the fixed dynamometer, the length of the movable fork tooth along the first direction X also changes, thereby altering the wheelbase.

[0011] To address the aforementioned technical problems, another technical solution adopted in this application is: a vehicle testing device, comprising: a fixed dynamometer; and an upgrade device for the aforementioned vehicle testing device; wherein, the wheelbase adjustment mechanism in the upgrade device is located between the mobile dynamometer and the fixed dynamometer, and is used to adjust the distance between the mobile dynamometer and the fixed dynamometer. Through the combined action of the fixed dynamometer and the upgrade device, all types of vehicles under test can be tested, and the wheelbase range of all types of vehicles under test can be effectively covered.

[0012] In some embodiments, the fixed dynamometer is an existing fixed dynamometer at the vehicle inspection site; the upgraded equipment is spaced apart from the fixed dynamometer, and a support assembly is provided between the upgraded equipment and the fixed dynamometer. By reusing the fixed dynamometer at the vehicle inspection site, costs and space occupation can be reduced. In addition, the support assembly can improve the overall strength of the vehicle inspection device.

[0013] In some embodiments, the vehicle detection device further includes an image acquisition unit, a distributor, and a controller. The image acquisition unit is used to acquire the license plate information of the currently detected vehicle. The distributor is used to distribute the vehicle to be detected to a preset vehicle detection device for detection based on the information of the vehicle to be detected and the information of the vehicles currently being detected by each vehicle detection device and the vehicles waiting in line for detection. The controller is used to send a detection command to the corresponding vehicle detection device when the license plate information of the currently detected vehicle matches the license plate information of the vehicle to be detected distributed by the distributor. Before sending a detection command to the corresponding vehicle detection device each time, the controller first confirms whether the license plate information of the currently detected vehicle matches the license plate information of the vehicle to be detected distributed by the distributor. This can reduce the risk caused by the mismatch between the detection command and the vehicle type.

[0014] In some embodiments, the fixed dynamometer includes a first roller assembly and a first motor; the mobile dynamometer includes a second roller assembly and a second motor; wherein the first motor and the second motor are synchronous motors; the fixed dynamometer is an existing fixed dynamometer at the vehicle testing site; wherein the information of the vehicle being tested includes wheelbase information; the controller is also used to control the wheelbase adjustment mechanism to adjust the distance between the mobile dynamometer and the fixed dynamometer based on the wheelbase information of the vehicle being tested. The controller controls the wheelbase adjustment mechanism to adjust the distance between the mobile dynamometer and the fixed dynamometer based on the wheelbase information of the vehicle being tested, which is compatible with the testing of different types of gasoline vehicles and new energy vehicles. Moreover, since the first motor of the fixed dynamometer and the second motor of the mobile dynamometer are two independent motors, there is no connection between the mobile dynamometer and the fixed dynamometer. Thus, simply installing the upgrade equipment near an existing fixed dynamometer at the vehicle testing site is sufficient to upgrade an existing single-axis fixed dynamometer into a dual-axis dynamometer.

[0015] In some embodiments, the fixed dynamometer includes a first roller assembly, and the mobile dynamometer includes a second roller assembly; a wheelbase adjustment mechanism is used to adjust the wheelbase between the first roller assembly and the second roller assembly; wherein the wheelbase between the first roller assembly and the second roller assembly is greater than or equal to 1920 mm and less than or equal to 3400 mm. By limiting the wheelbase range between the first roller assembly and the second roller assembly, the vehicle detection device can detect vehicles that meet the above-mentioned wheelbase, thereby improving the compatibility of the vehicle detection device.

[0026] Vehicles typically require inspection after a certain number of years of use. Existing vehicle inspection facilities generally have single-axle dynamometers. These dynamometers are usually used to test two-wheel-drive vehicles but cannot test four-wheel-drive vehicles. When a vehicle inspection facility needs to test four-wheel-drive vehicles, a dedicated dynamometer for this purpose needs to be established. In this case, the vehicle inspection facility would have two independent systems—one for the single-axle dynamometer and one for the dedicated four-wheel-drive dynamometer—which would occupy valuable space within the facility.

[0027] To address the issue that single-axle dynamometers in vehicle testing facilities are typically used for testing two-wheel-drive vehicles but cannot test four-wheel-drive vehicles, this application provides an upgraded version of a vehicle testing device. The upgraded device includes a support mechanism, a mobile dynamometer, and a wheelbase adjustment mechanism. The mobile dynamometer is mounted on the support mechanism and is movable relative to it. The wheelbase adjustment mechanism is fixed to the support mechanism and connected to the mobile dynamometer. The wheelbase adjustment mechanism drives the mobile dynamometer to move. The upgraded vehicle testing device comprises only one dynamometer: the mobile dynamometer.

[0028] This application utilizes the combined action of a load-bearing mechanism, a mobile dynamometer, and a wheelbase adjustment mechanism to change the position of the mobile dynamometer; and it can test vehicles of all drive types.

[0029] Please see Figure 1 as well as Figure 2 , Figure 1 This is a top view of a vehicle detection device according to one or more embodiments; Figure 2 This is a side view of a vehicle testing apparatus according to one or more embodiments. This application provides an upgrade device for a vehicle testing apparatus. The upgrade device 10a includes a support mechanism 11, a mobile dynamometer 12, and a wheelbase adjustment mechanism 13. The mobile dynamometer 12 is disposed on the support mechanism 11 and is movable relative to the support mechanism 11. The wheelbase adjustment mechanism 13 is fixed to the support mechanism 11 and connected to the mobile dynamometer 12. The wheelbase adjustment mechanism 13 is used to drive the mobile dynamometer 12 to move. The upgrade device 10a includes only one dynamometer, the mobile dynamometer 12.

[0030] The upgraded vehicle testing device 10a can be installed near the fixed dynamometer 20 at the vehicle testing site. The fixed dynamometer 20 can be, but is not limited to, a single-axle dynamometer. The fixed dynamometer 20 can test two-wheel drive vehicles, such as front-wheel drive or rear-wheel drive vehicles.

[0031] The load-bearing mechanism 11, as an integral support structure, can adopt a frame-type or box-type design. The load-bearing mechanism 11 provides an installation position for the mobile dynamometer 12 and the wheelbase adjustment mechanism 13.

[0032] The mobile dynamometer 12 is located above the support mechanism 11. The mobile dynamometer 12 can test vehicles that are rear-wheel drive or front-wheel drive. Under the action of the wheelbase adjustment mechanism 13, the mobile dynamometer 12 can move along the first direction X relative to the support mechanism 11. When the wheelbase adjustment mechanism 13 is not acting on the mobile dynamometer 12, both the mobile dynamometer 12 and the wheelbase adjustment mechanism 13 can be stationary. The first direction X can be the direction of travel of the vehicle being tested. The structure of the mobile dynamometer 12 can be similar to that of the fixed dynamometer 20 in the vehicle testing area, as long as it allows the mobile dynamometer 12 to move.

[0033] The wheelbase adjustment mechanism 13 can be located above and fixed to the support mechanism 11, which can improve the stability of the wheelbase adjustment mechanism 13 on the upgrade equipment 10a. The wheelbase adjustment mechanism 13 is detachably or fixedly connected to the mobile dynamometer 12. When the wheelbase adjustment mechanism 13 is working, it can drive the mobile dynamometer 12 to move along the first direction X, thereby adjusting the wheelbase range between the mobile dynamometer 12 and the fixed dynamometer 20 along the first direction X.

[0034] The upgraded equipment 10a for the aforementioned vehicle testing device only needs to include one dynamometer, the mobile dynamometer 12, and does not need to include the fixed dynamometer 20 already present at the vehicle testing site.

[0035] Through the combined action of the aforementioned support mechanism 11, the mobile dynamometer 12, and the wheelbase adjustment mechanism 13, the position of the mobile dynamometer 12 can be changed. When the upgrade equipment 10a is installed near the fixed dynamometer 20 at the vehicle testing site, the mobile dynamometer 12 can move relative to the fixed dynamometer 20 under the action of the wheelbase adjustment mechanism 13; the fixed dynamometer 20 tests front-wheel drive or rear-wheel drive vehicles, while the mobile dynamometer 12 tests rear-wheel drive or front-wheel drive vehicles. When the upgrade equipment 10a and the fixed dynamometer 20 at the vehicle testing site work together, they can test vehicles of all drive types and effectively cover the wheelbase range of vehicles of all drive types.

[0036] Please see Figure 3 , Figure 3This is a simplified structural diagram of a vehicle detection device according to one or more embodiments. (Combined with...) Figure 1 and Figure 2 In some embodiments, the upgraded vehicle testing device 10a further includes a signal interface (not shown in the figure). The signal interface is communicatively connected to the mobile dynamometer 12. The signal interface is configured to connect to both the diagnostic instrument 14 for new energy vehicles and the exhaust gas analyzer 15 for gasoline vehicles.

[0037] The signal interface serves as a medium connecting the mobile dynamometer 12 to the diagnostic instrument 14 or the exhaust gas analyzer 15. The signal interface can be compatible with both the diagnostic instrument 14 and the exhaust gas analyzer 15. The number of signal interfaces can be one, two, or more. The signal interface can connect to the diagnostic instrument 14 for new energy vehicles; or, the signal interface can connect to the exhaust gas analyzer 15 for gasoline vehicles.

[0038] In other embodiments, the signal interface may also be communicatively connected to the carrier mechanism 11 or the wheelbase adjustment mechanism 13, which is not limited here. When there are multiple signal interfaces, different signal interfaces may be provided in one, two, or all three of the carrier mechanism 11, the mobile dynamometer 12, and the wheelbase adjustment mechanism 13, which is not limited here.

[0039] The signal interface allows the device to connect to both the diagnostic instrument 14 for new energy vehicles and the exhaust gas analyzer 15 for gasoline vehicles, making the upgrade device 10a compatible with all types of vehicles being tested.

[0040] Specifically, the signal interface can be a plug-in signal interface (not shown in the figure). The diagnostic instrument 14 and the exhaust gas analyzer 15 can be connected to the mobile dynamometer 12 through plug-in signal interfaces, which can shorten the replacement time of the diagnostic instrument 14 and the exhaust gas analyzer 15 and improve the testing efficiency of the vehicle being tested.

[0041] In some embodiments, the signal interface is a single interface. Alternatively, the signal interface includes a first signal interface (not shown in the figure) and a second signal interface (not shown in the figure). The first signal interface is configured to connect to the diagnostic instrument 14 of a new energy vehicle. The second signal interface is configured to connect to the exhaust gas analyzer 15 of a gasoline vehicle.

[0042] When there is only one signal interface, it is a single interface. The single interface uses a standardized interface for universal connection. When the vehicle being tested is a gasoline-powered vehicle, the single interface can connect to the exhaust gas analyzer 15 for communication. When the vehicle being tested is a new energy vehicle, the single interface can connect to the diagnostic tool 14 for communication.

[0043] Alternatively, when there are two signal interfaces, the signal interfaces include a first signal interface and a second signal interface. The first signal interface can be connected to the diagnostic tool 14 of the new energy vehicle. The first signal interface is used for communication connection with the diagnostic tool 14. The second signal interface can be connected to the exhaust gas analyzer 15 of the gasoline vehicle. The second signal interface is used for communication connection with the exhaust gas analyzer 15.

[0044] The aforementioned single interface, first signal interface, and second signal interface can all be reserved as RS485 interfaces. These reserved RS485 interfaces can support the transmission of real-time detection data via the RS485 protocol.

[0045] A single interface can reduce the complexity of using the upgrade device 10a and achieve compatibility between gasoline vehicles and new energy vehicles. Alternatively, a first signal interface and a second signal interface can improve the stability of data transmission and achieve compatibility between gasoline vehicles and new energy vehicles.

[0046] The aforementioned single interface can be a pluggable first interface. The first signal interface can be a pluggable first signal interface. The second signal interface can be a pluggable second signal interface. During the testing of the vehicle by the upgrade equipment 10a, the corresponding exhaust gas analyzer 15 and diagnostic instrument 14 can be selected according to the type of the vehicle being tested.

[0047] The aforementioned upgraded device 10a can also be reserved with a 220V AC power port, enabling power connection, etc.

[0048] Continue reading Figures 1 to 3 In some embodiments, the upgraded device 10a of the vehicle detection device also includes a diagnostic instrument 14 for new energy vehicles and an exhaust gas analyzer 15 for gasoline vehicles.

[0049] The diagnostic instrument 14 is capable of performing three-electric system tests on new energy vehicles. These tests include tests on the battery, motor, and electronic control system. The diagnostic instrument 14 is a conventional component in this field and is not limited thereto. The exhaust gas analyzer 15 is capable of performing exhaust gas tests on gasoline-powered vehicles. The exhaust gas analyzer 15 is a conventional component in this field and is not limited thereto.

[0050] The diagnostic instrument 14 and the exhaust gas analyzer 15 can be connected to or disconnected from the upgrade equipment 10a, etc., depending on the actual situation. For example, the diagnostic instrument 14 and the exhaust gas analyzer 15 are only connected to the signal interface when the upgrade equipment 10a is in the detection state; the diagnostic instrument 14 and the exhaust gas analyzer 15 are disconnected from the signal interface when the upgrade equipment 10a is in the non-detection state.

[0051] When the upgraded device 10a is in a detection state or not in a detection state, the diagnostic instrument 14 and the exhaust gas analyzer 15 are connected to the corresponding signal interface, which can improve detection efficiency and reduce the risk of misconnection.

[0052] By limiting the upgrade equipment 10a to include the aforementioned diagnostic instrument 14 and exhaust gas analyzer 15, detection efficiency can be improved.

[0053] In some embodiments, the diagnostic instrument 14 for new energy vehicles includes an insulation resistance tester. The exhaust gas analyzer 15 for gasoline vehicles includes a five-gas analyzer 151 and / or a smoke meter 152.

[0054] Among them, the insulation resistance tester is used to test the insulation performance of new energy vehicles. An insulation resistance tester is a portable electronic instrument specifically designed to measure the insulation resistance of electrical equipment, wiring, or insulating materials. The insulation resistance tester is a conventional component in this field and is not limited thereto.

[0055] The five-gas analyzer 151 is used to detect five gaseous components in the exhaust gas of gasoline vehicles. The five-gas analyzer 151 is a conventional component in the art and is not limited herein. The smoke meter 152 is used to detect the smoke opacity in the exhaust gas of diesel vehicles. The smoke meter 152 is a conventional component in the art and is not limited herein.

[0056] The aforementioned insulation resistance tester can be connected to the diagnostic instrument 14 of the new energy vehicle via the first signal interface. The five-gas analyzer 151 and smoke meter 152 can be connected to their respective counterparts via the second signal interface. That is, the five-gas analyzer 151 and smoke meter 152 can share a single second signal interface, allowing for switching between different five-gas analyzers 151 and smoke meters 152 through a plug-and-play method.

[0057] In other embodiments, the signal interface includes a third signal interface (not shown in the figure). The second and third signal interfaces are respectively configured to connect to the corresponding exhaust gas analyzer 15 and smoke meter 152, etc.

[0058] The insulation resistance tester, the five-gas analyzer 151, and the smoke meter 152 mentioned above can be used to perform corresponding tests according to the different types of vehicles being tested.

[0059] It should be noted that the aforementioned insulation resistance tester, five-gas analyzer 151, and smoke meter 152 can be configuration components of the upgraded equipment 10a. Alternatively, the aforementioned insulation resistance tester, five-gas analyzer 151, and smoke meter 152 can be existing configuration components at vehicle inspection sites, which can improve reusability and thus reduce costs.

[0060] Please see Figure 4 and Figure 5 , Figure 4 This is a first partial side view of a vehicle detection device according to one or more embodiments; Figure 5 This is a first partial top view of a vehicle detection device according to one or more embodiments. (In conjunction with...) Figures 1 to 3In some embodiments, the wheelbase adjustment mechanism 13 includes a drive member (not shown in the figure) and a plurality of connecting members 131. The plurality of connecting members 131 are spaced apart between the drive member and the movable dynamometer 12. One end of each of the plurality of connecting members 131 is connected to the drive member, and the other end is connected to the movable dynamometer 12.

[0061] The driving component provides driving force. The driving component can be, but is not limited to, a driving cylinder or a driving motor. The number of connecting components 131 can be, but is not limited to, two or more. Multiple connecting components 131 are located between the driving component and the mobile dynamometer 12. One end of each connecting component 131 is detachably or fixedly connected to the drive shaft of the driving component. The other end of each connecting component 131 is detachably or fixedly connected to the mobile dynamometer 12. The driving component drives the multiple connecting components 131 to move the mobile dynamometer 12.

[0062] Through the combined action of the driving component, multiple connecting components 131 and the mobile dynamometer 12, the positional change between the mobile dynamometer 12 and the fixed dynamometer 20 can be adjusted. The structure is simple and easy to operate and install.

[0063] In one specific embodiment, there are two connecting members 131. The two connecting members 131 are a first connecting member (not shown in the figure) and a second connecting member (not shown in the figure). The drive shaft of the drive member is connected to the first connecting member. The second connecting member is connected to the movable dynamometer 12. The drive member drives the first connecting member to move closer to or further away from the second connecting member, thereby adjusting the movable dynamometer 12 to move closer to or further away from the fixed dynamometer 20, and thus adjusting the wheelbase between the movable dynamometer 12 and the fixed dynamometer 20. The aforementioned first and second connecting members can be, but are not limited to, gear drives, lead screw and nut drives, and slide rail drives, etc., and are not limited here.

[0064] In some embodiments, the support mechanism 11 includes a support platform 111 and a movable fork 112. The wheelbase adjustment mechanism 13 and the movable dynamometer 12 are both disposed on the support platform 111. The movable fork 112 is disposed on the side of the wheelbase adjustment mechanism 13 opposite to the support platform 111.

[0065] The support platform 111 serves as the basic support platform for the overall structure. The support platform 111 provides an installation location for the wheelbase adjustment mechanism 13 and the mobile dynamometer 12.

[0066] By positioning the movable fork 112 above the wheelbase adjustment mechanism 13, the movable fork 112 can provide a certain load-bearing capacity, thereby improving the overall strength of the upgraded equipment 10a. Furthermore, as the movable dynamometer 12 moves closer to or further away from the fixed dynamometer 20, the length of the movable fork 112 along the first direction X also changes, thus altering the wheelbase.

[0067] In one specific embodiment, the movable fork 112 is a telescopic movable fork (not shown in the figure). The telescopic movable fork includes multiple first movable fork 1121 and multiple second movable fork 1122. The multiple first movable fork 1121 are connected to the support platform 111, that is, the multiple first movable fork 1121 are in a fixed state. The multiple second movable fork 1122 are connected to the end of the movable dynamometer 12 facing the wheelbase adjustment mechanism 13. When the wheelbase adjustment mechanism 13 drives the movable dynamometer 12 to move closer to or away from the fixed dynamometer 20, the second movable fork 1122 can move closer to or away from the adjacent first movable fork 1121, and can adjust the overall length of the telescopic movable fork, etc.

[0068] Specifically, the plurality of first moving fork teeth 1121 and the plurality of second moving fork teeth 1122 are arranged along a second direction. The second direction can be perpendicular to the first direction. For example, the second direction can be, but is not limited to, a left-right direction. When the plurality of second moving fork teeth 1122 approach the plurality of first moving fork teeth 1121, one second moving fork tooth 1122 is inserted between two adjacent first moving fork teeth 1121, which can shorten the overall length of the telescopic moving fork teeth. In addition, by inserting the aforementioned second moving fork teeth 1122 between two adjacent first moving fork teeth 1121, the risk of movement deviation of the wheelbase adjustment mechanism 13 can be reduced, thereby improving the stability of the movement of the wheelbase adjustment mechanism 13.

[0069] Continue reading Figures 1 to 5 This application provides a vehicle testing device. The vehicle testing device 100 includes a fixed dynamometer 20 and an upgrade device 10a for the vehicle testing device. The wheelbase adjustment mechanism 13 in the upgrade device 10a is located between the mobile dynamometer 12 and the fixed dynamometer 20, and is used to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20.

[0070] The wheelbase adjustment mechanism 13 is located between the movable dynamometer 12 and the fixed dynamometer 20. The fixed dynamometer 20 can be located at the front axle position, and the movable dynamometer 12 can be located at the rear axle position. Alternatively, the fixed dynamometer 20 can be located at the rear axle position, and the movable dynamometer 12 can be located at the front axle position.

[0071] The wheelbase adjustment mechanism 13 drives the movable dynamometer 12 to move closer to or further away from the fixed dynamometer 20, thereby adjusting the distance between the movable dynamometer 12 and the fixed dynamometer 20. It should be noted that the upgrade device 10a in this embodiment is the same as the upgrade device 10a described in the above embodiments, and will not be repeated here.

[0072] Through the combined action of the fixed dynamometer 20 and the upgraded equipment 10a, it is possible to test vehicles of all drive types and effectively cover the wheelbase range of vehicles of all drive types.

[0073] Please see Figure 6 , Figure 6 This is a second partial side view of a vehicle detection device according to one or more embodiments. (In conjunction with...) Figures 1 to 5 In some embodiments, the fixed dynamometer 20 is an existing fixed dynamometer 20 at the vehicle testing site. The upgrade device 10a is spaced apart from the fixed dynamometer 20. A support assembly 30 is provided between the upgrade device 10a and the fixed dynamometer 20.

[0074] Before the upgrade device 10a is installed at the vehicle inspection site, the vehicle inspection site already has a fixed dynamometer 20. It is only necessary to install the upgrade device 10a near the fixed dynamometer 20.

[0075] There is a gap between the upgraded device 10a and the fixed dynamometer 20. Specifically, there is a gap between the wheelbase adjustment mechanism 13 and the fixed dynamometer 20; they can be connected or not. When the wheelbase adjustment mechanism 13 and the fixed dynamometer 20 are not connected, a rigid material can be filled between them to increase their strength. When the wheelbase adjustment mechanism 13 and the fixed dynamometer 20 are connected, they can be fixed together with bolts, etc.

[0076] The support component 30 is positioned above the aforementioned intervals and provides load-bearing capacity. The support component 30 is flush with both the surface of the upgrade device 10a and the surface of the fixed dynamometer 20. Other related structures can be installed in the space below the support component 30.

[0077] By reusing the fixed dynamometer 20 at the vehicle testing site, costs and space requirements can be reduced. Furthermore, the support assembly 30 can improve the overall strength of the vehicle testing device 100.

[0078] In some embodiments, the vehicle detection device 100 further includes an image acquisition unit 16, a distributor (not shown in the figure), and a controller (not shown in the figure). The image acquisition unit 16 is used to acquire the license plate information of the currently detected vehicle. The distributor is used to distribute the vehicle to be detected to a preset vehicle detection device 100 for detection based on the information of the vehicle to be detected and the information of the vehicles currently being detected by each vehicle detection device 100 and the vehicles waiting in the queue for detection. The controller is used to send a detection command to the corresponding vehicle detection device 100 when the license plate information of the currently detected vehicle matches the license plate information of the vehicle to be detected distributed by the distributor.

[0079] The image acquisition unit 16 can scan the vehicle registration certificates or license plates of different vehicles being inspected and obtain information about the vehicles, such as vehicle type and wheelbase. The image acquisition unit 16 can be a camera. The distributor guides vehicles to the corresponding vehicle inspection device 100 to queue, and the vehicles inspected by the vehicle inspection device 100 should be predetermined. However, some users may temporarily leave the inspection area, other vehicles may cut in line, or some vehicles may fail the inspection on the first attempt, requiring them to leave the vehicle inspection device 100 and re-enter. Therefore, before sending an inspection command to the corresponding vehicle inspection device 100 each time, it is necessary to confirm whether the license plate information of the currently inspected vehicle matches the license plate information of the vehicle to be inspected assigned by the distributor. This reduces the risk caused by a mismatch between the inspection command and the vehicle type.

[0080] If the license plate information of the currently detected vehicle is inconsistent with the license plate information of the vehicle to be detected assigned by the distributor, an alarm or a request can be issued to allow staff to confirm whether the detection command should be sent according to the actual license plate information of the currently detected vehicle detected by the image acquisition device 16.

[0081] In some embodiments, the fixed dynamometer 20 includes a first roller assembly 210 and a first motor (not shown in the figure). The mobile dynamometer 12 includes a second roller assembly 121 and a second motor (not shown in the figure). The first motor and the second motor are synchronous motors. The fixed dynamometer 20 is an existing fixed dynamometer 20 at the vehicle testing site. The information of the vehicle being tested includes wheelbase information. The controller is also used to control the wheelbase adjustment mechanism 13 to operate according to the wheelbase information of the vehicle being tested, so as to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20.

[0082] The first and second motors are synchronous motors, enabling synchronized rolling of the first roller assembly 210 and the second roller assembly 121. Since the first motor of the fixed dynamometer 20 and the second motor of the mobile dynamometer 12 are two independent motors, there is no connection between the mobile dynamometer 12 and the fixed dynamometer 20. Therefore, the existing single-axis fixed dynamometer 20 can be upgraded to a dual-axis dynamometer simply by installing the upgrade device 10a near the existing fixed dynamometer 20 at the vehicle testing site. The upgrade device 10a is described in detail above. If a belt or chain is used to achieve synchronized rolling of the first roller assembly 210 and the second roller assembly 121, the existing fixed dynamometer 20 at the vehicle testing site needs to be modified and upgraded, for example, by installing drive wheels, thus increasing the difficulty of upgrading the existing single-axis fixed dynamometer 20 to a dual-axis dynamometer. Furthermore, the fact that the first motor of the fixed dynamometer 20 and the second motor of the mobile dynamometer 12 are two independent motors allows the vehicle testing device 100 to test both front-wheel drive and rear-wheel drive vehicles.

[0083] The fixed dynamometer 20 can test vehicles with either front-wheel drive or rear-wheel drive. The mobile dynamometer 12 can test vehicles with either rear-wheel drive or front-wheel drive. The relative positions of the fixed dynamometer 20 and the mobile dynamometer 12 are not limited. The structures of the fixed dynamometer 20 and the mobile dynamometer 12 can be identical. The fixed dynamometer 20 can be, but is not limited to, a single-axis dynamometer.

[0084] One end of the wheelbase adjustment mechanism 13 is detachably or fixedly connected to the fixed dynamometer 20. The other end of the wheelbase adjustment mechanism 13 is detachably or fixedly connected to the movable dynamometer 12. The wheelbase adjustment mechanism 13 can adjust the distance between the movable dynamometer 12 and the fixed dynamometer 20, thereby adjusting different wheelbases.

[0085] The fixed dynamometer 20 can be stationary, while the movable dynamometer 12 can be in motion. In this case, the wheelbase adjustment mechanism 13 drives the movable dynamometer 12, causing a change in its position relative to the fixed dynamometer 20, thereby adjusting the distance between the movable dynamometer 12 and the fixed dynamometer 20. Alternatively, the fixed dynamometer 20 can be in motion, while the movable dynamometer 12 is stationary. In this case, the wheelbase adjustment mechanism 13 drives the fixed dynamometer 20, causing a change in its position relative to the movable dynamometer 12, thereby adjusting the distance between the movable dynamometer 12 and the fixed dynamometer 20. Alternatively, both the fixed dynamometer 20 and the movable dynamometer 12 can be in motion, and the wheelbase adjustment mechanism 13 simultaneously drives both, causing a relative change in their positions, thereby adjusting the distance between the movable dynamometer 12 and the fixed dynamometer 20.

[0086] Different vehicles being tested can have different wheelbases. The distance between the mobile dynamometer 12 and the fixed dynamometer 20 can be the wheelbase of the vehicle being tested. The controller can adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20 by controlling the wheelbase adjustment mechanism 13 based on the wheelbase information.

[0087] The controller described above controls the wheelbase adjustment mechanism 13 to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20 based on the wheelbase information of the vehicle being tested, which can be compatible with the testing of different types of gasoline vehicles and new energy vehicles.

[0088] After the controller completes the operation of the wheelbase adjustment mechanism 13, it can send a prompt command. This prompt command instructs the driver to drive the vehicle to be inspected onto the vehicle inspection device 100. Alternatively, the vehicle inspection device 100 may be equipped with a safety barrier (not shown in the figure). After the controller completes the operation of the wheelbase adjustment mechanism 13, the safety barrier automatically opens, allowing the driver to drive the vehicle to be inspected onto the vehicle inspection device 100.

[0089] Please see Figure 7 , Figure 7 This is a second partial top view of a vehicle detection device according to one or more embodiments. (In conjunction with...) Figures 1 to 6 In some embodiments, the fixed dynamometer 20 includes a first roller assembly 210. The mobile dynamometer 12 includes a second roller assembly 121. A wheelbase adjustment mechanism 13 is used to adjust the wheelbase between the first roller assembly 210 and the second roller assembly 121. The wheelbase between the first roller assembly 210 and the second roller assembly 121 is greater than or equal to 1920 mm and less than or equal to 3400 mm.

[0090] The first roller assembly 210 is used to drive the front or rear axle of the vehicle under test to rotate. The second roller assembly 121 can be used to drive the rear or front axle of the vehicle under test to rotate. The wheelbase adjustment mechanism 13 drives the mobile dynamometer 12 to move and can adjust the wheelbase D between the second roller assembly 121 and the first roller assembly 210.

[0091] The wheelbase between the first roller assembly 210 and the second roller assembly 121 along the first direction X may be, but is not limited to, 1920 mm, 2000 mm, 2100 mm, 2200 mm, 2300 mm, 2400 mm, 2500 mm, 2600 mm, 2900 mm, 3000 mm, 3200 mm, and 3400 mm.

[0092] By limiting the wheelbase range between the first roller assembly 210 and the second roller assembly 121, the vehicle detection device 100 is able to detect vehicles that meet the aforementioned wheelbase, thereby improving the compatibility of the vehicle detection device 100.

[0093] In one specific embodiment, the first roller assembly 210 includes a first sub-roller assembly 211 and a second sub-roller assembly 212. Both the first sub-roller assembly 211 and the second sub-roller assembly 212 extend along a second direction and are spaced apart. The distance between the end of the first sub-roller assembly 211 near the second sub-roller assembly 212 and the end of the second sub-roller assembly 212 near the first sub-roller assembly 211 is 700 mm. The distance between the end of the first sub-roller assembly 211 away from the second sub-roller assembly 212 and the end of the second sub-roller assembly 212 away from the first sub-roller assembly 211 is 2700 mm.

[0094] The second direction can be, but is not limited to, the left-right direction. For example, the first sub-roller assembly 211 and the second sub-roller assembly 212 extend in the left-right direction. The first sub-roller assembly 211 and the second sub-roller assembly 212 are spaced apart in the left-right direction. The first sub-roller assembly 211 is located on the left side of the fixed dynamometer 20, and the second sub-roller assembly 212 is located on the right side of the fixed dynamometer 20. That is, the distance between the right end of the first sub-roller assembly 211 and the left end of the second sub-roller assembly 212 is 700 mm. The distance between the left end of the first sub-roller assembly 211 and the right end of the second sub-roller assembly 212 is 2700 mm.

[0095] By limiting the width of the first sub-roller assembly 211 and the second sub-roller assembly 212 along the second direction, the wheelbase of both gasoline vehicles and new energy vehicles can be covered, thereby improving the compatibility of the vehicle detection device 100.

[0096] Similarly, the second roller assembly 121 includes a third sub-roller assembly (not shown in the figure) and a fourth sub-roller assembly (not shown in the figure). Both the third and fourth sub-roller assemblies extend along the second direction and are spaced apart. The distance between the end of the third sub-roller assembly closest to the fourth sub-roller assembly and the end of the fourth sub-roller assembly closest to the third sub-roller assembly is 700 mm. The distance between the end of the third sub-roller assembly furthest from the fourth sub-roller assembly and the end of the fourth sub-roller assembly furthest from the third sub-roller assembly is 2700 mm. By limiting the width of the third and fourth sub-roller assemblies along the second direction, the wheelbase of both gasoline-powered vehicles and new energy vehicles can be covered, thereby improving the compatibility of the vehicle detection device 100.

[0097] Continue reading Figures 1 to 7 In a specific application scenario, the upgrade device 10a includes a support mechanism 11, a mobile dynamometer 12, a wheelbase adjustment mechanism 13, a signal interface, an insulation resistance tester, a five-gas analyzer 151, and a smoke meter 152. The mobile dynamometer 12 is mounted on the support mechanism 11. The wheelbase adjustment mechanism 13 is connected to the mobile dynamometer 12. The wheelbase adjustment mechanism 13 is used to drive the mobile dynamometer 12 to move and to adjust the distance between the mobile dynamometer 12 and the fixed dynamometer 20. The first signal interface is configured to connect to a diagnostic instrument 14 for new energy vehicles. The second signal interface is configured to connect to the five-gas analyzer 151 and the smoke meter 152 for gasoline vehicles.
