The invention provides a bearing buffer unit for a motor, comprising motor spindles, wherein the motor spindles pass through the centers of a stator core and a rotor core, and are respectively fixed in the upper end cap and the lower end cap of a motor by an upper bearing device and a lower bearing device; the upper bearing device comprises upper end cap bearings which are fixed at the spindles; the upper end cap bearings are arranged in a concave platform of the upper end cap of the motor; the upper end cap bearings in the concave platform are respectively provided with an upper bearing elastic element in a radial direction; each upper bearing elastic element is provided with an upper sealing cover plate in an axial direction; the lower bearing device comprises lower end cap bearings which are fixed at the spindles; the lower end cap bearings are arranged in an inner concave platform of the lower end cap of the motor; each lower end cap bearing in the inner concave platform is provided with a lower bearing elastic element in a radial direction; and lower sealing cover plates are arranged in an outer concave platform of the lower end cap of the motor. The above technical scheme is used to overcome the defects that bearings for an existing motor are easily extruded mutually and damaged at the joints of the spindles and the end caps due to high-speed running, heat emission, parking, cooling, deformation and the like, the tail ends of the spindles of the motor are exposed and the like. The bearing buffer unit is used for controlling motors in different freezing operating rooms.

The invention relates to a solar photovoltaic assembly and a building curtain wall. The solar photovoltaic assembly comprises a first glass substrate, a solar cell layer, a second glass substrate, a third glass substrate, isolation bars and conjunction boxes. The solar photovoltaic assembly integrates advantages of a photovoltaic module and hollow glass, and adopts the first glass substrate as a light collecting surface; the second glass substrate and the third glass substrate can also carry out secondary or multiple reflections on rays leaked from gaps between the cells in a hollow cavity, so that light passing through the third glass substrate is allowed to be sufficient, and light utilization rate is improved; the building curtain wall formed by the solar photovoltaic assemblies ensures a certain indoor illumination intensity through light passing through the third glass substrate, thereby reducing lighting facilities; and besides, due to shelter of cells, light incident to the room can be reduced effectively, so that use amount of cooling devices can be reduced.

Embodiments of the present invention provide an antenna tuning method and a terminal. The method includes: when the first antenna is in the working state and the second antenna is in the standby state, acquiring the first working frequency band of the first antenna; according to the preset working frequency band of the first antenna and the corresponding relationship between the at least two second radio frequency channels, determine the target radio frequency channel corresponding to the first working frequency band among the at least two second radio frequency channels; control the second power amplifying unit to turn on The second antenna communicates with the target second radio frequency. In the embodiment of the present invention, the radiation power of the antenna in the working state is adjusted by using other antennas and the load on the radio frequency path that can be connected with other antennas, so that the antenna can work with better working efficiency, which can save The use of the antenna tuner is eliminated, and the production cost of the terminal is reduced.

The invention relates to the technical field of LED light sources, in particular to a high-reliability white light LED plane light source module adopting a metal substrate with a special grooved structure. The high-reliability white light LED plane light source module is characterized in that the upper surface of the metal substrate is provided with a special grooved structure, and the metal substrate is internally provided with a graphic circuit layer and an insulating layer having high reflectivity; an LED light emitting chip is directly arranged in the groove of the metal substrate, and the groove is filled by adopting transparent resin or silica gel; the LED light emitting chip is covered to form a filling layer, and a light scattering layer and a fluorescent powder layer are sequentially arranged on the filling layer. Compared with the prior art, the invention adopts automatic machining processes such as a laser engraving or dry-wet engraving method, and the like to manufacture the special groove so as to build good mounting environment for the chip, and moreover, by adding the combined use of the scattering layer and a light emitting layer, a formed plane has small light source thickness, strong area expandability, high stability, high brightness and good uniformity.
