The diameter of the bevel gear is smaller than that of the first gear, the diameter of the third gear is smaller than that of the second gear and that of the first gear, the design is to enlarge the transmission ratio when the bevel gear is transmitted to the second gear, and finally, the second gear can still drive the rack to obtain larger displacement under the condition that the bevel gear rotates a small amount.
When the distance between the rack and the bottom surface of the rack guide groove reaches the maximum, the included angle between the support plate and the swing plate is 75-85 degrees, and then in the range, the angle between the support plate and the swing plate is close to 90 degrees, so that the support force of the support plate to the swing plate is good, and the swing angle of the swing plate is large; the optimal included angle between the supporting plate and the swinging plate is 85 degrees, under the optimal included angle, the supporting force of the supporting plate to the swinging plate is better, the swinging angle of the swinging plate is optimal, and meanwhile, under the extrusion of the swinging plate to the supporting plate, the supporting plate can still return.
The second fixed block, the third fixed block and the fourth fixed block have the following functions: in the process that the steel wire rope is pulled, the second fixing block, the third fixing block and the fourth fixing block can play a role in relatively fixing the steel wire rope.
When the storage battery is located in the installation space of the machine, the storage battery protective shell is also located in the installation space, the sliding block is located at the bottom of the sliding block groove at the moment, the rack is located at the end of the rack guide groove, the pull ring is located below the cover plate, and the swing plate is located in the mechanism groove.
When a user needs to take out the storage battery from the installation space of the machine, the user firstly pulls out the pull ring from the lower part of the cover plate, and in the pulling-out process of the pull ring, the first steel wire rope pulls the rope distributor to move towards the direction of the second fixed pulley; under the pulling of rope distributor, first wire rope spring and second wire rope spring are pulled respectively to second wire rope and fourth wire rope, because the user has not mentioned the pull ring yet, and the wobble plate still is arranged in mechanism's groove this moment, and the slider still is arranged in slider groove bottom, so first wire rope spring and second wire rope spring are stretched. When the tab is fully pulled out from under the cover panel, the first and second wire springs are stretched to the longest.
After the user pulled up the pull ring and proposed the battery protective housing from installation space, the wobble plate no longer received spacingly, so under first wire rope spring and second wire rope spring's reset action, take first wire rope spring as an example: under the reset action of the first steel wire rope spring, the first steel wire rope spring pulls the sliding block to move towards the first steel wire rope spring through the third steel wire rope; in the process of moving the sliding block, the supporting plate and the swinging plate are supported, and the supporting plate and the swinging plate are swung out from the mechanism groove; in the process that the support plate supports the swing plate, the support plate swings around the pin, in the swinging process of the support plate, the pin also swings along with the support plate, so that the fifth gear can drive the rack to move in the rack guide groove through the fourth gear, the bevel gear, the first shaft, the first gear, the third gear, the second shaft and the second gear, the rack drives the sliding plate to slide in the hole of the sliding plate, and the sliding plate finally extends out of the hole of the sliding plate. When the sliding block moves to the limit position under the action of the first steel wire rope spring, the included angle between the supporting plate and the swinging plate is 85 degrees, and the distance of the sliding plate extending out of the hole of the sliding plate is the largest. Under such a condition, when the battery protective housing is carelessly fallen to subaerial, the sliding plate among the actuating mechanism touches ground earlier, and protection casing just can not directly touch mutually with ground like this, can also play the effect of buffering removal impact force simultaneously, and then can play the effect of protection casing, has finally avoided the battery in the battery protective housing to receive violent impact.
When the storage battery protective shell needs to be placed into the installation space of the machine again, a user can slide the reset snap ring downwards, in the process that the reset snap ring slides downwards, the swing plate and the supporting plate are extruded into the mechanism groove, and the sliding block returns to the bottom of the sliding block groove; in the process that the supporting plate is extruded into the mechanism groove, under the reverse rotation of the corresponding gear, the rack drives the sliding plate to return to the original position; in the process that the sliding blocks return to the bottom, the sliding blocks pull the corresponding steel wire ropes to return, then a user can swing the pull ring to a position which is level to the cover plate, and finally the pull ring and the pull ring are pulled back to the position below the cover plate under the corresponding steel wire ropes.
Compared with the traditional protective shell technology, the pull ring can be pulled out from the cover plate by a user, the first steel wire rope spring and the second steel wire rope spring are stretched to store energy in the pulling process, after the user lifts the pull ring and lifts the protective shell, the actuating mechanism is triggered under the reset action of the first steel wire rope spring and the second steel wire rope spring, the sliding plate in the actuating mechanism extends out, and finally the actuating mechanism can play a role in buffering the protective shell when the extending amount of the sliding plate is the longest; the invention has simple structure and better use effect.
