Description

Power supply trolley

Technical Field

The invention relates to the technical field of automobile manufacturing, in particular to a power supply trolley.

Background

Along with the continuous presentation of the intelligent networking technology, the whole vehicle power utilization modules are more and more, and the power utilization requirements of the modules are also more and more, for example, the modules such as an engine control module, a gearbox control module, an electric tail gate control module and a front-view multifunctional camera are used for on-line data refreshing, for example, a 60Ah automobile battery is used, the static electricity consumption of the automobile in the whole vehicle manufacturing process is about 6Ah when the automobile is in a full-open state (not started) of an electric appliance, and the voltage of a storage battery can be reduced to 12V from 12.6V, and the electricity consumption is about 30 Ah. The large electricity consumption of the electric inspection flash directly causes the problem of insufficient electricity of the storage battery in the field, the storage area and after sale of the vehicle. In the prior art, a whole vehicle ignition charging mode or a charging mode of a mobile charging station is adopted after the vehicle is off line, however, the time consumption of a brushing module of the electric detection equipment is 400s, 5 stations (6 meters on each station) are spanned, the operation workers are completely depended to move back and forth for 60 meters to take the equipment, and the time and the labor are wasted.

Disclosure of Invention

The invention aims to provide a power supply trolley which can supply power to electronic appliances on line and guarantee the electric quantity of a storage battery of the whole trolley.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a power supply trolley, includes the mounting panel and is connected with the machine that charges of pincers that charges, is provided with the walking wheel subassembly on the mounting panel, and the track clamp is arranged in between the walking wheel subassembly, and walking motor drive walking wheel subassembly is along orbital motion, and the below of mounting panel is provided with the tray that is used for placing MFT, and the quotation of tray is whole to be located the horizontal plane, and the elevating movement of vertical direction is made to elevator motor drive tray.

In the scheme, the rail is arranged above the main chain plate for conveying the vehicle, the power supply trolley is hung on the rail through the traveling wheel assembly and can roll along the rail, the power supply trolley synchronously moves along with the vehicle to supply power to different modules on the vehicle at different stations for module brush writing, and the electric quantity of the storage battery of the vehicle can not be consumed by utilizing a charger on the trolley during module brush writing, so that the electric quantity of the storage battery of the vehicle after leaving the factory is full.

Detailed Description

As shown in fig. 1, the power supply trolley comprises a mounting plate 10 and a charger 20 connected with charging clamps, wherein a traveling wheel assembly 31 is arranged on the mounting plate 10, a track is clamped between the traveling wheel assemblies 31, a traveling motor 32 drives the traveling wheel assembly 31 to move along the track, a tray 41 for placing MFT is arranged below the mounting plate 10, the whole disc surface of the tray 41 is positioned in a horizontal plane, and a lifting motor 42 drives the tray 41 to vertically lift. The track sets up in the top that is used for the main link joint of transport vehicle, and the power supply dolly hangs on the track and can roll along the track through walking wheel subassembly 31, and the power supply dolly carries out the module with a brush along with vehicle synchronous movement at different stations to the power supply of different modules on the vehicle, is the electric quantity that the machine that charges on the dolly provided when the module is brushed, consequently can not consume the electric quantity of vehicle self battery to guarantee to dispatch from the factory the electric quantity of back vehicle battery and be full electric quantity. Because need use MFT and vehicle to inserting when charging the vehicle, so be provided with tray 41 here and be used for placing MFT, tray 41 can drive MFT and move in the vertical direction, and when the vehicle arrived the station that needs the brush writing, tray 41 removed to the low level, makes things convenient for operating personnel to insert MFT and vehicle to, and when the vehicle left the station of brush writing, tray 41 rose to the high level, avoids colliding with vehicle or operating personnel, improves the security.

Since the power supply trolley moves along the rail, the power supply trolley cannot be supplied with power by using a conventional wire, the mounting plate 10 is further provided with a miller tube type current collector 50, and the miller tubes of the current collector 50 are in line contact with the rail and form a sliding fit, so that the problem of wiring is avoided.

In order to ensure that the tray 41 does linear motion in the vertical direction, and at the same time, because the MFT placed on the tray 41 has a certain weight, the tray 41 is connected with a guide rail 43 arranged in the vertical direction, the mounting plate 10 is provided with a guide rail groove 44 in a downward protruding manner, and the guide rail 43 and the guide rail groove 44 are mutually embedded to form guiding and sliding fit. The stability of the tray 41 in the vertical linear motion is ensured by the guiding and sliding fit between the guide rail 43 and the guide rail groove 44.

A power distributor 11 and a signal lamp 12 are fixed on the lower plate surface of the mounting plate 10, a direct current power supply 13 and a control box 14 are fixed on the upper plate surface of the mounting plate 10, and a cable hanging frame 15 for hanging charging clamps and various cables is connected to the end part of the mounting plate 10 far away from the tray 41.

In order to improve the stability of the connection between the power supply trolley and the track, a group of walking wheel assemblies 31 is respectively arranged at two ends of the mounting plate 10 in the walking direction, and each group of walking wheel assemblies 31 comprises 4 walking wheels which are 2 above and 2 below.

The tray 41 is provided with an anti-collision sensor 45, the anti-collision sensor 45 collects whether a barrier exists in front of the tray to prevent collision with the barrier, a position sensor 16 is also arranged at the end part of the mounting plate 10 adjacent to one side of the cable hanging frame 15, and the position sensor 16 detects a vehicle position signal on the main chain plate to prepare for following the power supply trolley.

The mounting plate 10 is also provided with a clutch (not shown in the figure), and the control box 14 controls the clutch to be connected with the chain below the track for synchronous action or to be separated from the chain below the track for independent action. That is to say, the power supply trolley and the chain below the track can move respectively at different speeds and also can move synchronously at the same speed, and under the condition that the power supply trolley needs to move at the same speed and at the same degree, the power supply trolley is connected with the chain through the clutch on the ride, so that on one hand, the synchronous action of the power supply trolley and the chain can be ensured, and on the other hand, the energy-saving effect is also achieved.
