Stricture of vagina securing member, flange nut, battery frame and battery modules.
Described threaded fastener includes connecting rod, connects blind hole, fastening cap and water proof ring.Described connecting rod is divided into
Upper, middle and lower three sections, connecting rod hypomere is provided with the external screw thread matched with flange nut and diameter is less than connecting rod epimere,
Being a changeover portion between connecting rod epimere and hypomere, connecting rod top is provided with axially extended connection blind hole, connects
Being provided with in blind hole and assemble the female thread that bolt adapts, threaded fastener is outside the outer periphery at connecting rod top
Extend a fastening cap, and have cannelure in fastening cap bottom surface, equipped with water proof ring in described cannelure.
The base plate of described battery frame is provided with the location unthreaded hole adapted with connecting rod epimere, and battery bottom is provided with dress
Distribution, threaded fastener is connected with flange nut by passing the connecting rod hypomere of location unthreaded hole, and assembling bolt is worn
Crossing pilot hole, lower end is connected with threaded fastener by connecting blind hole, and the water proof ring being forced to deformation can be for battery
Frame and threaded fastener provide in junction and effectively seal.
Threaded fastener integrates the function of screw bolt and nut, and bottom passes outside battery frame and passes through flange nut
Fixing self, top then realizes nested type by connection blind hole with assembling bolt and threadeds.Meanwhile, it is located at tightly
Gu the water proof ring on cap can also effectively prevent rainwater or dust from entering in battery frame, it is ensured that the IP protection of battery frame
Performance.Use above-mentioned attachment structure can avoid on battery frame base plate to arrange fixing screwed hole and reinforcement etc. attached
Structure, reduces design and the difficulty of processing of battery frame.
For ensureing the structural strength of threaded fastener, connect blind hole and at most can only extend to connecting rod stage casing.
For ease of the use of threaded fastener, fastening cap can be processed into regular hexagon.Regular hexagon fastening cap with
The matching of common tool is preferable.
For reinforcing battery frame base plate, also reinforcing plate can be set between battery frame base plate and flange nut.
In electrokinetic cell described in the utility model, battery modules is relatively easy to assembling with the attachment structure of battery frame, and
Change into being indirectly connected with by being directly connected to by the connected mode between battery modules and battery frame, meeting battery modules
Be conducive to simplifying the self structure of battery frame while requirement of shelter, reduce its manufacturing cost.
