The utility model belongs to the technical field of polishing devices, and particularly relates to a tricycle spindle polishing device which comprises a workbench and a polishing box, and a polishing mechanism and a dust collecting mechanism are arranged above the workbench. The grinding mechanism moves transversely and longitudinally, adjusts the grinding depth and moves in the length direction of the tricycle main shaft, and the action of grinding the surface of the tricycle main shaft is achieved. And the dust collecting mechanism is arranged above the grinding mechanism and is used for sucking dust generated by grinding the workpiece, so that the action of intensively collecting the dust generated by grinding is realized. According to the grinding device for the tricycle spindle, the grinding mechanism and the dust collecting mechanism are arranged, the grinding mechanism grinds the surface of the tricycle spindle, the dust collecting mechanism is arranged above the grinding mechanism, dust generated by grinding workpieces is collected in a centralized mode, and the problem that when an existing grinding machine works, the grinding efficiency is high is solved. And a large amount of dust damages operators and components of the grinding machine.

The application discloses an electronic invoice obtaining method and device, electronic equipment and a storage medium. The method comprises the following steps: extracting a first domain name, a full address and routing information from an electronic invoice obtaining request; selecting a proxy download server according to the first domain name and the full address; obtaining a supplier proxy IP address based on the proxy download server; sending an access request carrying the first domain name and the routing information to a supplier server by using the proxy download server according to the supplier proxy IP address, so that the supplier server obtains an electronic invoice corresponding to the routing information after receiving the access request, and sends the electronic invoice to the proxy download server; receiving the electronic invoice forwarded by the proxy download server; and forwarding the electronic invoice to a user end. The supplier server where the electronic invoice is located can be accessed more accurately, the accuracy of downloading the electronic invoice is improved, the success rate of obtaining the electronic invoice is improved, and the processing efficiency of an account business is improved.

This invention provides an indoor air conditioning unit and an air conditioner having the same, relating to the field of air conditioning equipment technology. It is designed to address the problem of damage to the middle frame, electrical control box, and left evaporator bracket of existing indoor air conditioning units during routine handling and installation. The unit includes a base, a middle frame covering the base, support components disposed between the base and the middle frame, and an inner component fixedly disposed relative to the base. Support components are provided at both ends of the middle frame, and the inner component is located between the two sets of support components. The support components include a middle frame support frame and a buffer component mounted on the middle frame support frame. The middle frame support frame is fixedly installed on the middle frame, and at each end of the middle frame, from the end of the middle frame towards the inner component, the buffer component protrudes from the corresponding middle frame support frame. The inner component includes the electrical control box and the left evaporator bracket. This invention can reduce damage to the middle frame, electrical control box, and left evaporator bracket of the indoor air conditioning unit during routine handling and installation.

This invention discloses a control method, device, storage medium, and vehicle for a vehicle tire blowout. The method includes: acquiring vehicle operating status information, wherein the operating status information includes at least: vehicle speed, vehicle slope information, vehicle wheel height, and vehicle spring pressure; determining vehicle wheel load information based on the operating status information; determining the vehicle's center of gravity position based on the wheel load information in response to a tire blowout; and controlling the vehicle to rise to a target height in response to the center of gravity position being within a target center of gravity range, wherein the target height is used to adjust the center of gravity position to the target center of gravity range, and the target center of gravity range is a triangular area formed by the wheel on the non-blowout side of the vehicle. This invention solves the technical problem of difficulty in reducing further damage to the tire and rim of a blowout tire by controlling the shift of the vehicle's center of gravity.
