However, in the prior art, the functional testing of the cab assembly mainly depends on the assembly of the chassis, which not only increases the complexity of the test, but also cannot effectively test the function of the cab assembly that is not assembled on the chassis, because there is no equipment in the vehicle factory to separately test the internal electronic control components or wiring harness of the cab assembly. Only after the whole vehicle is assembled can the electrical equipment and wiring harness in the car be tested, which makes it impossible to independently test the cab assembly and judge whether the internal equipment is intact. In the prior art, the cab assembly is installed on the cab and then tested, and then removed for transportation after the test is complete. It can be seen that this is very time-consuming and labor-intensive. Therefore, it is urgent to develop a device that can power the cab assembly that is not assembled on the chassis to assist in the detection of various parameters. Utility Model Content

[0021] It should be noted that the first connecting line 2 and the second connecting line 3 are both power lines, which can be but are not limited to: Figure 1The plug-to-plug connection method shown is used to jointly provide power for the function detection of the cab assembly. The voltage of the power supply can be selected according to actual needs and is not limited here. The ground wire 4 is used for grounding to protect the safety of electricity use. The above-mentioned inlets and outlets can be in the form of sockets, which is convenient for plugging together, so that the connection is more secure during the detection process. In the prior art, the cab itself is a complete set of equipment systems, including actuators such as seats, electric heating, headlights and other equipment, control mechanisms such as central control systems, operating buttons, etc., and detection mechanisms such as detection modules, display modules, etc. These devices form a complete system to ensure driving comfort and safety, but the cab itself has no power source. All power sources are provided by the chassis assembly. Because only the chassis assembly has equipment such as engines and battery packs to provide power sources, there is no way to detect it separately during the packaging and loading of the cab assembly. By adopting the solution of this embodiment, when the cab assembly needs to be inspected, it is only necessary to connect the portable power supply device to the cab assembly to realize power supply, and then the various performances of the cab assembly can be inspected, and power can be supplied without being installed on the chassis. The specific inspection process can be as follows: the inspection program is started through the control module, the inspection device performs a functional inspection on the cab assembly, and the inspection device sends the inspection data to the control module; the control module processes the inspection data and displays the results on the display module. When the inspection is completed, the portable power supply device can be easily removed, which is very convenient and greatly improves the inspection efficiency. In addition, the power supply assembly can be repeatedly charged at a low cost.

[0022] It can be known from the above description that in the embodiment of the portable power supply device for function detection of the cab assembly provided by the utility model, since it includes a power supply assembly, a first connecting line, a second connecting line and a ground line, the two ends of the first connecting line are respectively used to connect the first outlet of the power supply assembly and the first inlet of the detection component in the cab assembly, the two ends of the second connecting line are respectively used to connect the second outlet of the power supply assembly and the second inlet of the detection component, and the two ends of the ground line are respectively used to connect the grounding component and the ground line interface of the detection component, so the power supply assembly and the cab assembly can be connected as one by using these three lines, and the power supply assembly can be used. Power is supplied to the cab assembly, which is very convenient to operate and quickly detects various parameters of the cab assembly. When the detection is completed, the connecting wire can be easily unplugged to quickly separate the power supply assembly and the cab assembly. The cab assembly can enter the next process, and the power supply assembly can continue to be connected to another cab assembly for auxiliary detection. It can be seen that the above-mentioned portable power supply device for functional testing of the cab assembly avoids the tedious operation of installing the cab assembly on and removing it from the chassis, and can improve the detection efficiency and accuracy of the cab assembly that is not assembled on the chassis, and reduce the detection cost.

[0023] In a specific embodiment of the portable power supply device for detecting the function of the cab assembly, the power assembly 1 can be a 24V power assembly, the first outlet 11 of the power assembly 1 is a 24V outlet, the first inlet 51 of the detection component 5 is a 24V inlet, and the first connecting line 2 is a 24V power line. Further, the second outlet 12 of the power assembly 1 is a 0V outlet, the second inlet 52 of the detection component 5 is a 0V inlet, and the second connecting line 3 is a 0V power line. Furthermore, the grounding component 6 can preferably be a grounding pile. In this way, a complete 24V power supply circuit is formed to realize the 24V power supply to the cab assembly. Of course, other voltages can be selected according to actual needs, which is not limited here, and the first outlet 11 and the second outlet 12 of the power assembly 1 can be connected with joints by welding to ensure the firmness of the joint connection and improve the service life. Of course, other connection methods can also be selected according to actual needs, which is not limited here.

[0024] In another specific embodiment of the above-mentioned portable power supply device for detecting the function of the cab assembly, reference may be made to Figure 1 , both ends of the ground wire 4 can be preferably provided with clamps. In this case, the clamp-type connection method can improve the convenience of installation and disassembly during use, and further improve the detection efficiency. Of course, other connection methods can also be selected according to actual needs, which is not limited here.

[0025] In another specific embodiment of the above-mentioned portable power supply device for testing the function of the cab assembly, one end of the first connecting line 2 used for connecting the power assembly 1 can be provided with an anti-error component to prevent plugging in the wrong direction. Furthermore, in the above-mentioned portable power supply device for testing the function of the cab assembly, one end of the first connecting line used for connecting the power assembly is provided with a locking buckle. It should be noted that the locking buckle is in the shape of a raised buckle. After one plug is connected to the other half of the plug, the locking buckle will be stuck into the groove of the other half of the plug to lock the two plugs to prevent them from falling off during the detection process, further ensuring the safety of the detection. Of course, other locking methods can also be selected according to actual needs, which is not limited here. Specifically, the socket specification can be preferably DJ7034Y-7.8, which is a special wiring harness connector for automobiles, and has both anti-error and anti-fool functions.

[0026] In a preferred embodiment of the above-mentioned portable power supply device for cab assembly function detection, the first connecting wire 2, the second connecting wire 3 and the ground wire 4 can all be preferably high temperature resistant and wear resistant cables. Specifically, the high temperature resistant and wear resistant cable can adopt the national standard GN500℃ cable, or the German standard polyvinyl chloride material harness, i.e. FLRY-B4.0, to ensure that it will not break or age during long-term use, thereby improving the service life and eliminating the need to frequently replace the connecting wire. Of course, other types of connecting wires can also be selected according to actual needs, which is not limited here.

[0027] In another preferred embodiment of the above-mentioned portable power supply device for detecting the function of the cab assembly, the outer layer of the first connecting line 2, the second connecting line 3 and the ground line 4 can be preferably wrapped with an EMC metal shielding sleeve, which can prevent the electromagnetic waves at the work site from interfering with the power supply system, thereby better ensuring the stability of the power supply voltage, and the detection can be more accurate. It should be noted that electromagnetic compatibility (EMC) refers to the ability of a device or system to operate in accordance with the requirements in its electromagnetic environment and not to produce intolerable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the device to the environment in which it is located during normal operation cannot exceed a certain limit; on the other hand, it means that the device has a certain degree of immunity to the electromagnetic interference in the environment, that is, electromagnetic sensitivity. Of course, other types of shielding sleeves can also be selected according to actual needs, which is not limited here.

[0028] In another preferred embodiment of the above-mentioned portable power supply device for detecting the function of the cab assembly, reference Figure 2 , Figure 2 The present invention is a schematic diagram of the internal structure of a power supply assembly of another preferred embodiment of a portable power supply device for detecting the function of a cab assembly. The power supply assembly 1 may include a housing 13, a DC mobile power supply 14 and a DC voltage regulator 15 both of which are arranged inside the housing 13, wherein the DC mobile power supply 14 and the DC voltage regulator 15 are connected by a snap-on connection, and a first output port of the DC voltage regulator 15 connected by a wiring harness is a first outlet of the power supply assembly, and a second output port of the DC voltage regulator 15 connected by a wiring harness is a second outlet of the power supply assembly, and the DC voltage regulator 15 and the wiring harness are welded together.

[0029] It should be noted that this type of power supply assembly 1 can ensure the output of stable 24V / 6A DC power. Because the DC mobile power supply is limited by the stability of the battery pack, the voltage is different after just charging and after using for a period of time. Therefore, in order to ensure the safety of the cab assembly, this composition is adopted. A snap-on connection can be adopted between the DC mobile power supply 14 and the DC voltage regulator 15, which is convenient for removing the power supply for charging. Welding is adopted between the DC voltage regulator 15 and the wiring harness, which can reduce the loosening failure of the wiring harness interface.

[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
