Self-adaptive temperature control type charging pile shutter based on shape memory effect driving

Abstract

The invention relates to a self-adaptive temperature control type charging pile shutter based on shape memory effect driving. The self-adaptive temperature control type charging pile shutter comprisesa blade assembly (1) and a window frame assembly (2). The blade assembly (1) comprises a set of upper blades (11), lower blades (12) and shape memory alloy sheets (13), wherein the upper blades (11),the lower blades (12) and the shape memory alloy sheets (13) are connected. The window frame assembly (2) comprises a pair of outer frames (21) arranged on the two sides of the blade assembly (1). Arotating shaft (22), a fan-shaped sheet (23), a limiting screw (24) and an adjusting base (25) are arranged in the outer frame (21) on each side, wherein the rotating shaft (22), the fan-shaped sheet(23), the limiting screw (24) and the adjusting base (25) are matched with one another. An annular clamping base (26) is arranged on each adjusting base (25) and sleeved with a shape memory spring (27). One end of each shape memory spring (27) right faces the corresponding fan-shaped sheet (23). The self-adaptive temperature control type charging pile shutter has the beneficial effects that the blades have the self-adaptive opening and closing capacity, a charging pile has the regional differentiation heat dissipation and sealing capacity, driving force is sufficient, the stability is good, and the heat dissipation effect is improved.

Description

technical field [0001] The invention relates to the technical field of charging pile shutters, in particular to an adaptive temperature-controlled charging pile shutter driven based on a shape memory effect. Background technique [0002] The shutter is an important external structure of the new energy vehicle charging pile. On the one hand, the structure can prevent dust and rainwater from entering the pile, and on the other hand, it can leave a certain gap to ensure the air circulation inside and outside the pile and play a role in heat dissipation. In the working state, a large amount of heat will be generated inside the pile body in a short time, and the large blade angle can ensure good heat dissipation performance and ensure the safe use of the charging pile; in the non-working state, the pile body pays more attention to dustproof and waterproof performance, which requires a small The blade angle ensures its tightness. Therefore, this contradictory use requirement has ...
