Detailed Description
The following description of the embodiments refers to the accompanying drawings.
As shown in fig. 1 and 2, the biaxial hinge in the present embodiment includes a first hinge base 10, a second hinge base 30, and an intermediate hinge plate 20. The middle hinge plate 20 is in a groove shape, the length direction of the groove is a vertical direction, the direction of the groove opening is a first direction, the first groove wall 21 of the middle hinge plate is hinged with the first hinge seat 10 at the groove opening through a vertical first pin shaft 11, the second groove wall 22 is hinged with the second hinge seat 30 at the groove opening through a vertical second pin shaft 31, and a locking device for locking and fixing the middle hinge plate 20 and the second hinge seat 30 into a rigid whole is arranged between the second groove wall 22 and the second hinge seat 30.
The locking device comprises a second fixing plate 41 fixed on the outer side of the first groove wall 22 and a first fixing plate 42 fixed on the second hinge base 30, wherein the first fixing plate 42 is positioned above and vertically adjacent to the second fixing plate 41, a bolt 43 capable of moving up and down is arranged on the first fixing plate 42, a pin hole 411 for inserting the bolt 43 is arranged on the second fixing plate 41, and the bolt 43 is coaxially aligned with the pin hole 411 when the second hinge base 42 rotates a preset angle relative to the middle hinge plate 20 in a back direction.
A second pin hole 412 is further formed in the second fixing plate 41, into which the bolt 43 is inserted, and the bolt 43 is coaxially aligned with the second pin hole 412 when the second hinge base 30 is rotated to a predetermined angle in the first direction with respect to the intermediate hinge plate 20.
The locking device further comprises a bolt mounting plate 44, one end of the bolt mounting plate 44 is fixed on the first fixing plate 42, the other end of the bolt mounting plate 44 is suspended above the first fixing plate 42, and a bolt 43 is vertically inserted and mounted in a hole of the end portion of the bolt mounting plate 44 suspended above the first fixing plate 42. A limit cotter pin 45 is attached to the plug 43 at a position between the plug attachment plate 44 and the first fixing plate 42. The cotter 45 prevents the latch 43 from being completely pulled out from above the latch mounting plate 44 and also prevents the latch 43 from falling off from below the second fixing plate 41. The upper end of the bolt 43 is fixedly provided with a handle 46 for pulling the bolt 43 upwards.
The first fixing plate 42 is fixedly disposed on the second hinge base 30, the second fixing plate 41 is fixedly disposed on the second groove wall 22, and the second fixing plate 41 can support the first fixing plate 42.
The first hinge base 10 is provided with a limiting block 12 for limiting the rotation angle of the middle hinge plate 20 towards the first direction. The middle hinge plate 20 rotates about the first pin 11 relative to the first hinge base 10 by about 90 degrees along the first direction and then is in limited contact with the limiting block 12.
As shown in fig. 3 to 7, the battery compartment 62 of the electric forklift is provided with the side door 50, and the side door 50 is mounted by the above-mentioned biaxial hinge, wherein the first hinge seat 10 is fixedly connected to the frame 61 inside the cover 63, the second hinge seat 30 is fixedly connected to the side door frame 51 inside the door panel 52, and the first direction of the biaxial hinge is the opening direction of the side door 50.
As shown in fig. 3, when the side door 50 is opened from the closed state, the latch 43 is inserted into the pin hole 411 of the second fixing plate 41, the middle hinge plate 20 is locked to the second hinge base 30 by the locking device to form a rigid whole, and the side door 50 drives the second hinge base 30 and the middle hinge plate 20 to rotate around the first pin 11 for opening for the first time. After the middle hinge plate 20 rotates about 90 degrees relative to the first hinge base 10, the middle hinge plate 20 contacts with the limiting block 12 on the first hinge base for limiting, and at this time, the second groove wall 22 of the middle hinge plate 20 rotates to the outer side of the covering part 63. After the bolt 43 is pulled out from the pin hole 411, the second hinge seat continues to rotate along the first direction around the second pin shaft 31, so that the side door 50 is opened for the second time, when the side door rotates until the bolt 43 is coaxially aligned with the second pin hole 412, the bolt 43 slides downwards under the action of gravity to be inserted into the second pin hole 412, so that the middle locking between the second hinge seat and the middle hinge plate is realized, and at the moment, the side surface is positioned on the outer side of the covering part and is basically parallel to the covering part, so that the side door is completely opened. After the bolt 43 is inserted into the second pin hole 412, the side door can not rotate continuously around the second pin shaft, the opening angle of the side door is limited, and the side door is prevented from being collided with a vehicle body due to the opening angle of the side door, so that paint on the surface of the side door is damaged.
In this embodiment, the hinge is located the inboard of door plant and covering when the battery compartment side door is in the closed condition, accomplishes the hinge and hides, and when the side door was opened, the rotatable 180 degrees angles of side door had the biggest space when realizing that the battery compartment side door is opened.
