Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
The hinge is a component which is generally applied to two connected parts and can rotate relatively around a hinge center, and in practical application, two hinge bodies can rotate simultaneously or one hinge body can rotate relative to the other hinge body so as to meet specific functional requirements.
Without loss of generality, the present embodiment takes the hinge shown in the figures as a description main body, and of the two hinge bodies hinged with each other, the first hinge body 1 can be rotationally switched between two working positions relative to the second hinge body 2. In addition, the present embodiment will be described with reference to the use case where the first hinge body 1 is connected to a device cover (not shown) and the second hinge body 2 is connected to a device base (not shown), so as to clearly express the operation principle of the hinge according to the present embodiment. In which the first hinge body 1 shown in fig. 1 is in a first working position (lid open state) and the second hinge body 2 shown in fig. 2 is in a second working position (lid closed state). It should be understood that the specific structural form of the hinge and its specific application do not constitute a substantial limitation on the technical solution claimed in the present application.
As shown in fig. 1 and 2, the hinge further comprises a locking stop 3 and an elastic member (4) for self-locking of the working position. The locking block 3 is hinged to the second hinge body 2 and can be rotationally switched between a locking position and an unlocking position relative to the second hinge body 2, and the locking portion 31 of the locking block 3 is specifically configured as follows: the locking portion 31 in the locking position is fitted against the convex portion 11 of the first hinge body 1 to keep the first hinge body 1 in the open working position (first working position) shown in fig. 1; the locking portion 31 in the unlocking position (shown in fig. 5) can release the abutting fit with the protrusion 11, so that the first hinge body 1 is rotated and switched to the closed working position (second working position) shown in fig. 2, and the corresponding hinge body can normally realize the rotation and switching. Wherein, the elastic component (4) is arranged between the second hinge body 2 and the locking stop 3, here, the elastic component can adopt the tension spring 4 shown in the figure, as long as it can deform and store energy and release the deformation and store energy in the deformation recovery process, for example, the tension spring, the plate spring or the rubber component, etc. The tension spring 4 can generate deformation energy storage along with the rotation of the locking stop block 3, and can release the deformation energy storage to provide a first acting force F1 for the locking stop block 3 to rotate, reset and keep in the locking position. Please also refer to fig. 7.
So set up, based on this hinge self-locking function that has, can avoid rotating to switch to closed operating position unusually to accessible elastic component makes locking dog 3 restore to the throne and keeps at the locking position, and the in-process need not the operator and operates, can ensure that the hinge body that is located open operating position is in reliable locking state.
It is understood that the two working positions of the hinge according to the present solution, such as, but not limited to, the "first working position" corresponds to the "open working position" of the device cover, and the "second working position" corresponds to the "closed working position" of the device cover; in fact, it is also possible that the "first working position" corresponds to the "closed working position" of the device cover, and the "second working position" corresponds to the "open working position" of the device cover, as long as the application is applied to the change of the relative working position between the two hinge bodies through the rotation switching of the two hinge bodies, and the application is within the scope of the claims of the present application.
In particular, the articulation of the two hinge bodies of the hinge can be realized in different structural forms. In the scheme, the hinged end 12 of the first hinge body 1 is folded inwards to form a thin plate shape, and the hinged end 21 of the second hinge body 2 is arranged oppositely in a split mode and forms an insertion space; during assembly, the hinge end 12 of the first hinge body 1 is inserted into the hinge end 21 of the second hinge body 2, and the hinge joint between the first hinge body and the second hinge body can be realized by adopting the adaptive pin shaft 51 and the shaft end retainer ring 52. Referring also to fig. 3, there is shown an exploded view of the hinge assembly of the present embodiment.
Further, the locking stopper 3 can also be inserted into the second hinge body 2, and the hinge connection between the locking stopper and the second hinge body is realized through the pin shaft 6. Wherein, a fixed pin 41 and a fixed pin 42 are respectively arranged on the second hinge body 2 and the locking stop 3, one end of the tension spring 4 is hung on the fixed pin 41 to form a first connection point A, and the other end is hung on the fixed pin 42 to form a second connection point B.
In order to obtain stable self-locking performance, preferably, the locking portion 31 of the locking stopper 3 is adapted to abut against the convex portion 11 of the first hinge body 1 located at the opening operation position (the first operation position), and may be specifically configured as follows: the first hinge body 1, which has a tendency to switch to the closed operating position (second operating position), has a force F3 exerted by the protrusion 11 on the locking portion 31 passing through the hinge center of the locking stopper 3 to ensure a stable and reliable locking state. Reference is also made to fig. 4, which is a partially schematic illustration of the characteristic points of the open operating position shown in fig. 1.
In addition, the operability of the locking dog 3 for switching between the two operating positions can be further optimized.
As a further preferable mode, the locking stopper 3 further has a reset portion 32, and the reset portion 32 is circumferentially spaced from the locking portion 31, where "circumferential" refers to a rotational direction in which the locking stopper 3 rotates. Specifically, the locking stopper 3, which is switched from the locking position (fig. 1 and 4) to the unlocking position (fig. 2) in a counterclockwise direction (first direction), has a locking portion 31 on one side of the convex portion 11 and a resetting portion 32 on the other side of the convex portion 11, as shown in fig. 2; the first hinge body 1 switched to the closed working position has a convex portion 11 capable of abutting against a side surface of the reset portion 32, as shown in fig. 6, and pushes the locking stopper 3 in a clockwise direction (second direction) to switch to the locking position shown in fig. 7, at which time the first hinge body 1 is in the closed working position; when the first hinge body 1 is switched to the open working position, as shown in fig. 8, the convex portion 11 of the first hinge body can abut against the side surface of the locking portion 31 located at the locking position, and the locking stopper 3 is pushed in the counterclockwise direction to rotate until the convex portion 11 is disengaged from the locking portion 31, as shown in fig. 9, the locking stopper 3 is then located at the locking position, and at this time, the first hinge body 1 is located at the open working position shown in fig. 4. Reciprocating in this way, the operability of switching the working positions is greatly improved by the matching of the convex part 11 on the first hinge body 1 and the locking part 31 and the resetting part 32 on the locking stopper 3.
Accordingly, the tension spring 4 may also generate a deformation energy storage in accordance with the rotation of the locking stopper 3 that is rotationally switched to the unlocking position, as shown in fig. 5, and may release the deformation energy storage to provide the second acting force F2 that the locking stopper 3 is held in the unlocking position. Specifically, when the lock stopper 3 is located at the unlocked position (fig. 5), the line connecting the first connection point a and the second connection point B is located at the side of the hinge point thereof with the second hinge body 2 to release the second acting force F2 that the deformation energy storage provides that the lock stopper 3 is held at the unlocked position; when the protrusion 11 of the first hinge body 1 pushes the locking stopper 3 to rotate in the counterclockwise direction until the protrusion 11 disengages from the locking portion 3 (fig. 9), the line connecting the first connection point a and the second connection point B is located at the other side of the hinge point to release the first acting force F1 for providing the locking stopper 4 to return to the locking position by the deformation energy storage.
In addition, the surface of the convex part 11, which is matched with the locking part 31 in a propping manner, is an inner arc surface, as shown in the figure, the inner arc surface can effectively reduce the clamping stagnation possibly occurring between the matching surfaces in the working position switching process, and the smooth degree of the dynamic matching relation can be further improved. As shown in the drawings, the outer peripheral surfaces of the locking portion 31 and the restoring portion 32 may be circular arcs concentric with the hinge center, that is, the outer peripheral surfaces thereof are concentric and equal-diameter circular arcs. The structure design is relatively compact, and meanwhile, the processing manufacturability is better.
Furthermore, a wrench 7 may be provided on the locking dog 3. To apply a force to rotate the latch dog 3 to the unlocked position. Of course, the wrench 7 can also be used during debugging and maintenance, so as to be adjusted according to the operation requirement.
Taking the specific application of the first hinge body 1 connected to the device cover and the second hinge body 2 connected to the device base as an example, the following will briefly explain the specific operation principle of the present solution with reference to the features of the hinges shown in fig. 4 to 9 in the using process:
(1) in the open operating position (first operating position) shown in fig. 1 and 4, the protrusion 11 and the locking portion 31 are adapted against each other to handle the locked state, while the pre-tensioned tension spring 4 further provides a holding force;
(2) as shown in fig. 4, when it is required to switch to the closed working position (second working position), the operator can manually pull the wrench 7 upward, and the locking stopper 3 rotates counterclockwise to the unlocking position shown in fig. 5; in this state, a connecting line of the first connecting point a and the second connecting point B of the tension spring 4 is located on one side of a hinge point of the locking stopper 3 and the second hinge body 2, so as to release the second acting force F2 that the deformation stored energy provides to keep the locking stopper 3 in the unlocking position;
(3) when the first hinge body 1 is switched from the working position shown in fig. 6 to the closed working position, one side of the inner concave arc surface of the convex part 11 can push the reset part 32 of the locking stop block 3 in the clockwise direction (the second direction), and when the two parts are separated from each other as shown in fig. 7, the first hinge body 1 is in the closed working position; meanwhile, a connecting line of the first connecting point a and the second connecting point B of the tension spring 4 is located at the other side of the hinge point to release a first acting force F1 for providing the locking stopper 4 to be reset to the locking position by deformation energy storage, so that the locking stopper 3 is reset and kept at the locking position;
(4) when the first hinge body 1 needs to be switched to the open working position again, along with the rotation of the first hinge body 1, as shown in fig. 8, the convex portion 11 may abut against the side surface of the locking portion 31 located at the locking position, and push the locking stopper 3 to rotate in the counterclockwise direction until the convex portion 11 is disengaged from the locking portion 31.
(4) As shown in fig. 9, the lock stopper 3 disengaged from the protrusion 11 is rotated clockwise by the tension spring 4, and is returned to the lock position shown in fig. 4.
The holding of the two operating positions of the locking dog 3 may be secured by an elastic member as described above, or may be controlled by setting the position of the center of gravity of the locking dog itself. Specifically, the lock stopper 3 has a center of gravity positioned such that: in the condition shown in fig. 5, the weight of the locking dog 3 creates a first torque which provides that it remains in the unlocking position; in the state shown in fig. 4 and 9, the weight of the locking dog 3 creates a second torque that provides its return to the locked position. Under the action of corresponding torque, the corresponding function of maintaining the working position can be achieved.
In addition to the aforementioned hinges, this embodiment also provides an apparatus comprising a base and a lid hinged using a hinge edge as described above. It is to be noted that functional components such as the base body and the cover body of the device are not the core invention of the present application, and those skilled in the art can implement the functional components according to the prior art, so detailed description is omitted here.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
