Description

[0001] This invention is a divisional application. The application number of the original application is 201811452323.9 and the application date is November 30, 2018. Technical Field

[0002] The invention relates to a buckle structure, and in particular to a buckle structure which has a simple structure and can be quickly buckled and released. Background Art

[0003] In existing electronic devices, in order to prevent the electronic device from being opened during the process of carrying and moving, a snap structure is provided for the electronic device that can be opened and closed by the snap structure. Among the existing snap structures, there are simple snap structures that are manually operated by the user, and the user's operation is required both when snapping and releasing the snap to move the snap to the snap position and return to the initial position. There are also more complex structures that can make the snap move to the snap position, and as long as a force is applied, the snap can be returned to the initial position under the action of the structure. However, in order to make the snap return to the initial position after the snap is released, an overly complex structure is often used, which increases the manufacturing cost and complicates the assembly process. Summary of the invention

[0004] The object of the present invention is to provide a snap-fit ​​structure for snapping together a first shell and a second shell, which simplifies the structure and is easy to assemble, can greatly reduce manufacturing components and manufacturing costs, and also simplifies the manufacturing assembly process and assembly time.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A buckle structure, used for buckling a first shell and a second shell, comprising:

[0007] A buckling portion, the buckling portion being disposed on the first shell;

[0008] Hook section;

[0009] A tension spring, one end of which is arranged on the second housing, and the other end of which is arranged on the hook portion;

[0010] The hook portion moves between a locking position and a releasing position. When the hook portion is forced to move to the locking position, the hook portion is locked with the locking portion. When the hook portion is forced to disengage from the locking portion, the tension spring provides a restoring force to return the hook portion to the releasing position.

[0011] The setting of the tension spring can assist the movement and engagement of the hook portion. When the hook portion moves to the engagement position, the tension spring provides a tension force so that the hook portion can firmly engage the first shell and the second shell. When the hook portion is forced to disengage from the engagement portion, the tension spring will pull the hook portion back to the release position without requiring excessive user operations. Moreover, the setting of the tension spring simplifies the structure and simplifies assembly, which can greatly reduce manufacturing components and costs, and also simplify the manufacturing and assembly process and time.

[0012] In some embodiments, the buckle portion includes a first buckle slot and a second buckle slot, and the first buckle slot and the second buckle slot are arranged on opposite sides of a side of the first shell, so that the hook portion can be buckled to the buckle portion for buckling regardless of whether the first shell is installed forward or reverse.

[0013] In some embodiments, the hook portion includes a body and an operating portion, and the operating portion is disposed on a side surface of the body away from the second shell. The operating portion can make it easier for the user to operate the hook portion and improve the operating feel during operation.

[0014] In some embodiments, the hook portion includes a body, a hook, and two sliding shafts, wherein the hook is disposed at one end of the body, and the two sliding shafts are disposed at both sides of the body and slidably disposed on the second housing. The sliding shafts extending from the body to both sides are slidably disposed on the second housing, so that the hook portion is limited to move in a specific direction, and the hook portion is prevented from moving too far away from the buckle position or the release position during the movement. At the same time, the problem of excessive stretching of the tension spring and causing damage due to excessive displacement of the hook portion can also be avoided.

[0015] In some embodiments, the second housing includes a receiving recess and two limiting guide grooves, the two limiting guide grooves are arranged on opposite sides of the receiving recess, the hook portion is arranged in the receiving recess, and each of the sliding shafts is slidably arranged in one of the limiting guide grooves. By arranging the limiting guide grooves and the receiving recess on the second housing, a movement range of the hook portion in a specific direction can be provided to prevent the hook portion from moving to a non-locking position when the user applies force, or from not returning to the original release position after the force is released.

[0016] In some embodiments, the hook portion further includes two limiting members, which are respectively arranged on one side of the sliding shaft facing the bottom surface of the second housing, so as to provide a limiting function for the bottom when the hook portion moves to the release position.

[0017] In some embodiments, the hook portion includes a body, a hook, and a rib, wherein the hook is disposed at one end of the body, and the rib is disposed on the body and has an inclined surface on a side facing the second shell. The inclined surface allows the hook portion to protrude outward when pushed upward to the buckling position so that the hook portion can be buckled with the buckling portion.

[0018] In some embodiments, the second housing includes a protrusion, which is arranged at a position corresponding to the convex rib, so that the convex rib abuts against the protrusion when sliding. This can provide the abutting effect of the convex rib and reduce the weight of the second housing without providing a whole plane of protrusions for the convex rib to abut against during the sliding process.

[0019] In some embodiments, the body is provided with two positioning ribs, and the two positioning ribs are located on the left and right sides of the convex rib. The positioning ribs located on the left and right sides can provide left and right limiting functions.

[0020] In some embodiments, the protrusion includes a first protrusion and two second protrusions, wherein the first protrusion is disposed at a position corresponding to the protruding rib, and the two second protrusions are correspondingly located outside the two positioning ribs. Through the cooperation between the first protrusion and the protruding rib, and the cooperation between the second protrusion and the positioning rib, the hook portion can be prevented from moving too far away from the buckle position or the release position during the movement. At the same time, it can also be prevented from being over-stretched and damaged by the tension spring due to excessive displacement of the hook portion.

[0021] The beneficial effects of the present invention are as follows: through the above structure, the buckle structure allows the user to operate the hook part with one hand and blindly, and easily switch the state of the hook part between the buckle position and the release position. When the hook part is forced to move to the buckle position, the hook part is buckled with the buckling part. When the hook part is forced to disengage from the buckling part, the tension spring provides a restoring force to return the hook part to the release position; when the hook part is forced to disengage from the buckling part, the tension spring will pull the hook part back to the release position without requiring excessive operation by the user, thereby simplifying the structure and simplifying assembly, which can greatly reduce manufacturing components and manufacturing costs, and also simplify the manufacturing assembly process and assembly time.

[0034] Reference Figure 1 The buckle structure 10 of this embodiment is used to buckle the first shell 91 and the second shell 92 of the electronic device 90. Here, the electronic device 90 is described by taking a notebook computer as an example, but the present invention is not limited to this. For the convenience of description, only part of the first shell 91 and the second shell 92 are shown here.

[0035] The buckle structure 10 includes a buckle portion 11, a hook portion 12 and two tension springs 13. Figure 1 , the buckle part 11 is disposed on the first shell 91, and the hook part 12 is disposed on the second shell 92. In this embodiment, although the buckle part 11 is disposed on the first shell 91 and the hook part 12 is disposed on the second shell 92, the present invention is not limited thereto. The buckle part 11 and the hook part 12 are not limited to which shell they are disposed, as long as they can be disposed at corresponding positions on the two shells to be buckled with each other.

[0036] Reference Figure 1 In this embodiment, the buckle portion 11 is disposed at the middle position of the long side of the first shell 91, and the buckle portion 11 includes a first buckle groove 111 and a second buckle groove 112. The first buckle groove 111 and the second buckle groove 112 are disposed on opposite sides of one side of the first shell 91. Figure 3 In the cross-sectional view, the first buckle groove 111 is recessed on a side of the first housing 91 adjacent to the second housing 92, and the second buckle groove 112 is disposed on a side relatively far from the second housing 92. With the buckle grooves disposed on both sides, the hook portion 12 can be buckled into the first buckle groove 111 or the second buckle groove 112 of the buckling portion 11 for buckling regardless of whether the first housing 91 is installed forward or reverse.

[0037] In this embodiment, although the buckle portion 11 is described by taking two buckle grooves as an example, in other embodiments, for example, for the first shell 91 that cannot be flipped for use, only one buckle groove adjacent to the second shell 92 can be provided for the hook portion 12 to buckle.

[0038] Please continue to refer to Figure 1 and Figure 2 In this embodiment, two tension springs 13 are used for illustration, and the two tension springs 13 are arranged on the left and right sides of the hook portion 12. However, in other embodiments, only one tension spring 13 may be arranged to provide the force required by the hook portion 12. In this embodiment, one end of each tension spring 13 is arranged on the second housing 92, and the other end is arranged on the hook portion 12. Figure 2 One end of the tension spring 13 is fixed to the hook portion 12 in a hooking manner, and the other end is fixed to the second housing 92 by a locking screw 20 .

[0039] The hook portion 12 can be moved to a locking position (such as Figure 6 and Figure 7 ) and a release position (as shown Figure 1 and Figure 3 As shown), when the hook portion 12 is located as shown Figure 3When the user wants to close the buckle structure 10, he can apply force to the hook portion 12. Figure 4 As shown in FIG. 1 , after receiving the force toward the second housing 92, it will first rotate outward. Then, if it continues to receive the force toward the upper side, it will rotate as shown in FIG. Figure 5 As shown, the hook 123 of the hook 12 is moved to the outer side of the first buckle groove 111 corresponding to the buckle part 11. When it moves to this position, the internal tension spring 13 continuously applies an inward force to the hook part 12, that is, a clockwise rotation force is generated, thereby driving the hook 123 of the hook part 12 to buckle in the first buckle groove 111. At this time, the hook part 12 is buckled in the buckle part 11, that is, Figure 6 As shown, the hook portion 12 is located at the buckling position. When the hook portion 12 is buckled with the buckling portion 11, as shown in FIG. Figure 7 As shown, the tension spring 13 in the second shell 92 will continue to exert force on the hook portion 12 due to being stretched, so that the hook portion 12 continues to force the first hook groove 111 of the first shell 91 to firmly buckle the first shell 91 and the second shell 92.

[0040] Then, when the buckle state is to be released, after the hook portion 12 is forced to disengage from the first buckle groove 111 of the buckling portion 11, the tension spring 13 will provide a restoring force to return the hook portion 12 to the release position (such as Figure 1 and Figure 3 As shown in FIG. 1 ). The user only needs to apply force to the top of the hook portion 12 to disengage it from the first buckle groove 111, and the hook portion 12 will return to the initial release position under the restoring force of the tension spring 13. The hook portion 12 can be positioned without excessive user operations. Moreover, the provision of the tension spring 13 simplifies the structure and simplifies assembly, which can greatly reduce manufacturing components and costs, and also simplify the manufacturing and assembly process and time.

[0041] Next, the specific structure of the hook portion 12 will be described. Figures 1 to 3 The hook portion 12 includes a body 121, an operating portion 122, a hook 123, two sliding shafts 124, two limiting members 125, a convex rib 126, two positioning ribs 127 and a stopper 128. Figure 1 and Figure 3 The operation portion 122 is disposed on a side surface of the body 121 away from the second housing 92 and also located on a side away from the first housing 91. Figure 3 As shown, the operating portion 122 is located near the bottom and left side of the body 121. When the user applies force to the hook portion 12 to move it, the user can apply force to the operating portion 122 to provide the user with an operating feel.

[0042] Also refer to Figure 3The hook 123 is disposed at one end of the body 121, and is engaged with the first hook groove 111 of the buckling portion 11 on the first shell 91, so the hook 123 is located at one end of the body 121 adjacent to the first shell 91. Figure 2 , two sliding shafts 124 are disposed on both sides of the body 121 and are slidably disposed in the second housing 92. In this embodiment, the second housing 92 includes a receiving recess 921 and two limiting guide grooves 922. The two limiting guide grooves 922 are disposed on opposite sides of the receiving recess 921. Figure 1 When the hook portion 12 is installed to the second housing 92 , the hook portion 12 will be placed in the accommodating recess 921 , and the two sliding shafts 124 will be slidably disposed in one of the limiting guide grooves 922 , respectively.

[0043] When the hook portion 12 is subjected to force, the hook portion 12 will only move up and down along the limiting guide grooves 922 under the limiting action of the two sliding shafts 124 and the two limiting guide grooves 922. And under the left and right limiting of the accommodating recess 921, the hook portion 12 will not move left and right during the force-bearing process. In this way, the hook portion 12 can be limited to move in a specific direction, and the hook portion 12 can be prevented from moving too far away from the buckle position or the release position during the movement. At the same time, the problem of excessive stretching of the tension spring 13 and damage caused by excessive displacement of the hook portion 12 can also be avoided.

[0044] like Figures 2 to 4 As shown, a rib 126 and two positioning ribs 127 are provided on the body 121, and a slope 1261 is provided on the side of the rib 126 facing the second housing 92. In this embodiment, one rib 126 is used as an example for explanation, but multiple ribs 126 can also be provided to assist in sliding displacement. In addition, in this embodiment, reference can be made to Figure 2 The positioning ribs 127 on the left and right sides of the convex rib 126 are more protruding than the convex rib 126 in the middle. The positioning ribs 127 on the left and right sides can provide left and right limit functions, which will be further described later. The convex rib 126 in the middle provides the function of limiting movement. However, the present invention is not limited to this arrangement.

[0045] Reference Figure 2, the second shell 91 includes three protrusions, and the first protrusion 923 located in the center is arranged at a position corresponding to the rib 126, so that the rib 126 can be pressed against the first protrusion 923 when sliding. The second protrusions 924 located on the left and right sides will be located on the outside of the two positioning ribs 127. In other words, when the hook portion 12 is arranged in the receiving recess 921, the two positioning ribs 127 will be located between the left and right second protrusions 924. The positioning rib 127 located on the left side will be adjacent to or even slightly against the right side surface of the second protrusion 924 on the left side, and the positioning rib 127 located on the right side will be adjacent to or even slightly against the left side surface of the second protrusion 924 on the right side. Furthermore, when the hook portion 12 moves to the buckle position or returns to the release position, the positioning rib 127 and the second protrusion 924 can further play the role of left and right limit of the hook portion 12 in the receiving recess 921. In this way, the hook portion 12 can be prevented from moving too far away from the buckle position or the release position during the movement, and the problem of the extension spring 13 being damaged by excessive extension due to excessive displacement of the hook portion 12 can be avoided.

[0046] In this embodiment, the first protrusion 923 and the second protrusion 924 are provided at the positions corresponding to the protruding ribs 126 and the two positioning ribs 127, but in other embodiments, a whole protruding plane may be provided so that the protruding ribs 126 can abut against the protruding plane, and more protruding stoppers are provided on the left and right of the protruding plane. By providing the first protrusion 923 and the second protrusion 924, the areas outside the first protrusion 923 and the second protrusion 924 can be hollowed out, so that the thickness of the second shell 92 here can be thinner, thereby reducing more materials and weight.

[0047] Please refer to Figure 2 , a stopper 128 is provided on the body 121 below the hook 123. The stopper 128 will protrude slightly in the direction away from the body 121 than the sliding shaft 124. After the hook portion 12 is arranged in the receiving recess 921, the sliding shaft 124 will be slidably arranged in the left and right limiting guide grooves 922. At this time, the stopper 128 will correspondingly abut or abut against the two more protruding second protrusions 924. When the hook portion 12 is to be restored from the buckling position to the release position and the buckling of the hook 123 of the hook portion 12 is released, it will move to the receiving recess 921 under the action of the tension spring 13, and hit the components located in the receiving recess 921 under the action of the force. At this time, the stopper 128 is used to directly hit the second protrusion 924 first, so that other slender components such as the convex rib 126 and the positioning rib 127 can be prevented from being directly hit by a large force and causing deformation.

[0048] Furthermore, since the stopper 128 protrudes slightly away from the main body 121 compared to the sliding shaft 124, when the stopper 128 abuts against the second protrusion 924, the sliding shaft 124 will not directly abut or collide with the side wall of the limiting guide groove 922, and the wear that may be caused by the sliding shaft 124 moving back and forth in the limiting guide groove 922 can also be avoided.

[0049] Please refer to Figure 1 , Figure 2 and Figure 7 The two stoppers 125 of the hook portion 12 are respectively disposed on one side of each sliding shaft 124 facing the bottom surface of the second housing 92 to provide a stopper function at the bottom when the hook portion 12 moves to the release position. Figure 1 As shown, when the hook portion 12 is in the release position, the hook portion 12 is accommodated in the accommodating recess 921. At this time, the stopper 125 will stop at the bottom surface of the second shell 92, so that the hook portion 12 is positioned in the accommodating recess 921 and will not move downward. Figure 6 The buckle position shown is released. When the hook portion 12 is released from the force, it rebounds to the release position under the action of the restoring force of the tension spring 13. When the hook portion 12 rebounds to the bottom of the second shell 92, the limiting member 125 will first press against the bottom of the second shell 92, so that the hook portion 12 is positioned and restricted in the accommodating groove 921, and will not move downward any further.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
