The application discloses a frameless vehicle door body B column reinforcing structure and belongs to the technical field of automobile manufacturing, which comprises a B column inner plate assembly, a B column reinforcing piece and an outer plate reinforcing plate assembly. On the basis of the original B column inner plate assembly, a plurality of Z-direction long holes are arranged on the inner side of the B column inner plate along the body height direction, and the B column reinforcing piece is assembled on the Z-direction long holes. The B column reinforcing piece optimizes the corresponding position intrusion amount of the B column in the collision. The B column inner plate assembly provided with the B column reinforcing piece is welded with the outer plate reinforcing plate assembly, and a closed reinforcing cavity is formed between the B column inner plate assembly and the outer plate reinforcing plate assembly, which can effectively absorb the collision energy and make up for the sharply reduced outer cavity space. The frameless vehicle door body B column reinforcing structure can optimize and correct the corresponding position intrusion amount of the B column in the collision without adjusting the welding tooling, thereby saving the correction period and cost and being beneficial to the lightweight of the new energy vehicle body.

This invention relates to the field of LED display technology, and more particularly to an LED module, wherein at least two driving components and the main circuit to which these at least two driving components belong constitute a driving module; there are more than one driving module on the back of the circuit board; within each driving module, the input terminal of the first driving component is connected to the main circuit, and the first driving component to the last driving component are connected in series to achieve data signal conduction; the main circuit receives data signals on the back of the circuit board; within each driving module, a serial data jumper component is provided on the serial data connection line between any two adjacent driving components; the serial data jumper component enables unfaulty / uncut driving components to connect with other driving components / main circuits within the driving module. Its advantages are that after cutting the circuit board, there is no need to change the circuit design, saving the production cycle of multi-form LED displays and repetitive design.

The invention discloses a hydrogen fuel cell system life prediction system which comprises the following steps: a model construction module constructs an electric pile life prediction empirical model based on historical durability data of a hydrogen fuel cell system and stage characteristics of voltage attenuation of an electric pile of a hydrogen fuel cell; the life prediction module obtains a corresponding attenuation correction coefficient through a pile life prediction empirical model by utilizing historical durability data and combining with a parameter adjustment rule, obtains a pile minimum monolithic voltage attenuation curve corresponding to each reference current through the attenuation correction coefficient, and calculates a pile minimum monolithic voltage attenuation curve; and calculating to obtain a life prediction value corresponding to each reference current in the preset scene, and selecting the minimum life prediction value as a final life prediction value. By predicting the service life of the hydrogen fuel cell system, the memory occupation is reduced, and the cost is saved.

The invention relates to the technical field of robots, and provides an equipment control method, a cleaning robot and a cleaning system.The method comprises the steps that a pet searching instruction sent by terminal equipment for a target pet is responded, a pet searching task is triggered, and at least one patrol area and patrol points in each patrol area are determined; controlling the cleaning robot to move to an inspection point according to a preset inspection sequence, and executing pet searching operation in an inspection area corresponding to the inspection point; and if the pet searching operation is completed in all the inspection areas or the pet information of the target pet is obtained in any inspection area, ending the pet searching task, determining a pet searching result and sending the pet searching result to the terminal equipment. The pet searching time or period can be effectively saved, and the pet searching efficiency is improved.
