Description

Technical Field

[0001] The invention belongs to the technical field of safety doors, and in particular relates to a new aluminum profile spliced ​​safety door for a pure electric bus. Background Art

[0002] Pure electric vehicles are vehicles that are driven by electric motors, and the driving power comes from an onboard rechargeable energy storage system. Pure electric vehicles are vehicles that use onboard power as power, use electric motors to drive the wheels, and meet the requirements of road traffic and safety regulations. Because their impact on the environment is relatively small compared to traditional vehicles, their prospects are widely optimistic, even though the current technology is not yet fully mature.

[0003] Pure electric vehicles are vehicles that are powered entirely by rechargeable batteries (such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries or lithium-ion batteries). Although it has a long history of 186 years, it has always been limited to certain specific applications and the market is relatively small. The main reason is that various types of batteries are generally high in price, short in life, large in size and weight, and long in charging time.

[0004] At present, there are too many customized products with different sizes of safety doors for exported buses according to the regulations of different countries. The cost of developing stamping molds is as high as more than 1 million. For small batches of customized products, most of them use aluminum profiles to splice safety doors; however, there are still various problems with the various spliced ​​safety doors on the market.

[0005] For example, the platform safety door for trains to stop at any position disclosed in the authorization announcement number CN211081511U has realized the use of two sets of staggered door bodies, and each sliding door is independently provided with a power mechanism to drive it to slide left and right, which broadens the sliding range and freedom of each sliding door. Each staggered adjacent movable door can be opened and closed. Any position on the platform is a door opening area, and the train does not need to stop accurately. It is easy to realize any stop of any model of train, which is convenient for passengers to get on and off safely. However, it does not solve the problem that the existing internal safety door skin and the frame are not smooth at the bonding edge, and putty cannot be used at the right angle, which will cause cracking. If it is not treated, the product appearance quality will be affected; the interior covering parts installed at the hinge and the lock installation need to be cut on site, which affects the appearance quality. The gluing and sealing of the edges of interior parts affects the quality of the product appearance, and the cutting positions of hinges and locks are difficult to seal. During the rain test, rainwater will enter the interlayer between the door panel and the interior parts through the gap, causing leakage and water accumulation. For this reason, we propose a new aluminum profile splicing safety door for pure electric buses. Summary of the invention
