Description

Technical Field

[0001] The present invention relates to child products, and more particularly to a buckle assembly.

Background Art

[0002] With the development of the economy and the progress of technology, there are more and more consumer products available in the market that bring convenience to people's lives. Child carriers are one of the consumer products.

[0003] It is well known that straps are essential for child carriers, and buckle assemblies are commonly used with the straps for fastening or unfastening them.

[0004] Currently, conventional buckle assemblies include a male buckle, a female buckle for engaging with the male buckle, and a release button. The release button can disengage the male buckle and the female buckle from each other. The release button is typically disposed on the front or rear surface of one of the male buckle and the female buckle to provide easy access for a user to operate the release button. However, since the release button is disposed in such a prominent location, it is easy for a child sitting in a child carrier to recognize the presence of the release button, which leads to a potential danger caused by an unintended release operation of the buckle assembly because the child may unconsciously touch it. On the other hand, when the release button of a conventional buckle assembly is operated, it is necessary to apply a large force to the release button, which causes difficulty in the release operation. Further, the configuration of the release button disposed on the front or rear surface of one of the male buckle and the female buckle increases the possibility of being hit by other objects, which invites a potential danger caused by an unintended release operation of the buckle assembly. There are buckle assemblies having unobtrusive release buttons, but such buckle assemblies have complex structures and difficult release operations.

[0005] Therefore, there is a need to provide an improved buckle assembly that solves the above-mentioned problems.

Mode for Carrying Out the Invention

[0065] In order to illustrate the technical specifications, structural configurations, achieved objects and effects of the present invention, related embodiments and drawings are described below.

[0066] Refer to FIGS. 1 to 6. FIG. 1 is a schematic view of a buckle assembly 100 according to a first embodiment of the present invention. FIG. 2 is a view of a second buckle component 2 of the buckle assembly 100 according to the first embodiment of the present invention. FIGS. 3 and 4 are exploded views of the buckle assembly 100 according to the first embodiment of the present invention. FIG. 5 is a partial view of the buckle assembly 100 according to the first embodiment of the present invention. FIG. 6 is a cross-sectional view of the buckle assembly 100 according to the first embodiment of the present invention. As shown in FIGS. 1 to 6, the buckle assembly 100 includes a first buckle component 1, a second buckle component 2, an operating component 3, and two elastic components 6. The second buckle component 2 includes a locking portion 4. The first buckle component 1 includes a locked portion 5 configured to cooperate with the locking portion 4. The locking portion 4 engages with the locked portion 5 in the lateral direction when the first buckle component 1 is mated with the second buckle component 2 along a mating direction that may be the direction of arrow P shown in FIG. 6. In this embodiment, the first buckle component 1 can be a male buckle, and the second buckle component 2 can be a female buckle. However, it is not limited to this embodiment. In another embodiment, the first buckle component can be a female buckle, and the second buckle component can be a male buckle.

[0067] The operating component 3 is partially embedded within the second buckle component 2 and is partially exposed from the side wall of the second buckle component 2. The operating component 3 is configured to cooperate with the locking portion 4 and is slidable relative to the second buckle component 2 along the lateral direction. It should be noted that in this embodiment, the lateral direction can be the direction of arrow M1 or M2 shown in FIG. 5. The operating component 3 drives the locking portion 4 to move away from the portion 5 to be locked in order to disengage the locking portion 4 from the portion 5 to be locked during the sliding movement of the operating component 3 relative to the second buckle component 2 along the lateral direction. Since the sliding direction of the operating component 3 can be the same as or opposite to the moving direction of the locking portion 4, the force applied to the operating component 3 provided by the user can be completely transmitted to the locking portion 4 along the sliding direction, disengaging the locking portion 4 from the portion 5 to be locked, which prevents the dispersion of forces in different directions and ensures an easy and labor-saving unlocking operation of the buckle assembly 100.

[0068] The portion 5 to be locked is disposed on the front surface (front side surface) of the first buckle component 1. A fitting hole 21 is formed in the second buckle component 2 to allow passage of the portion 5 to be locked, and the fitting direction (front-back direction), which is the direction of arrow P shown in FIG. 6, intersects the sliding direction of the operating component 3, which can be the direction of arrow M1 or M2 shown in FIG. 5. Such a configuration can reduce the thickness of the buckle assembly 100 along the fitting direction and enable a reasonable use of the internal space of the buckle assembly 100.

[0069] Specifically, as shown in FIGS. 3 to 6, the lock portion 4 has an elastic structure. The operation component 3 elastically deforms the lock portion 4 along the lateral direction in order to disengage the lock portion 4 from the portion 5 to be locked during the sliding operation of the operation component 3 with respect to the second buckle component 2. More specifically, the lock portion 4 includes a first lock portion 4a and a second lock portion 4b. The first lock portion 4a and the second lock portion 4b are disposed on both sides of the portion 5 to be locked and clamp the portion 5 to be locked along the lateral direction. The operation component 3 includes a first operation component 3a and a second operation component 3b. The first operation component 3a and the first lock portion 4a are disposed on the same side. The second operation component 3b and the second lock portion 4b are disposed on the other same side. The first operation component 3a is configured to cooperate with the second lock portion 4b. The second operation component 3b is configured to cooperate with the first lock portion 4a. In order to disengage the first lock portion 4a and the second lock portion 4b from the portion 5 to be locked during the sliding operation of the operation component 3 with respect to the second buckle component 2, the first operation component 3a and the second operation component 3b are each deformed in a direction away from the portion 5 to which the second lock portion 4b and the first lock portion 4a are locked. The cooperation between the first operation component 3a and the second lock portion 4b and the cooperation between the second operation component 3b and the first lock portion 4a make the engagement operation and the release operation of the buckle assembly 100 more reliable. However, the structures of the operation component and the lock portion are not limited to this embodiment. For example, in another embodiment, the operation component can include one, three, or four operation components, and the lock portion can correspondingly include one, three, or four lock portions.

[0070] As shown in FIGS. 3 to 6, the first locking portion 4a includes a first elastic arm 41a and a first locking head 42a connected to the first elastic arm 41a. The first elastic arm 41a is configured to cooperate with the second operating component 3b. The first locking head 42a is configured to engage with the portion 5 to be locked. The first elastic arm 41a is biased to engage the first locking head 42a with the portion 5 to be locked. The second operating component 3b elastically deforms the first elastic arm 41a in a direction away from the portion 5 to be locked in order to disengage the first locking head 42a from the portion 5 to be locked during the sliding movement of the second operating component 3b relative to the second buckle component 2. The second locking portion 4b includes a second elastic arm 41b and a second locking head 42b connected to the second elastic arm 41b. The second elastic arm 41b is configured to cooperate with the first operating component 3a. The second locking head 42b is configured to engage with the portion 5 to be locked. The second elastic arm 41b is biased to engage the second locking head 42b with the portion 5 to be locked. The first operating component 3a elastically deforms the second elastic arm 41b in a direction away from the portion 5 to be locked in order to disengage the second locking head 42b from the portion 5 to be locked during the sliding movement of the first operating component 3a relative to the second buckle component 2.

[0071] Preferably, in this embodiment, the second operation component 3b can be configured to push the first elastic arm 41a so as to elastically deform the first elastic arm 41a in a direction away from the portion 5 where the first elastic arm 41a is locked, and the first operation component 3a can be configured to push the second elastic arm 41b so as to elastically deform the second elastic arm 41b in a direction away from the portion 5 where the second elastic arm 41b is locked. That is, the force acting on the operation component 3 provided by the user can be a pushing force. However, it is not limited to this embodiment. For example, in another embodiment, the first operation component can be configured to pull the first elastic arm to elastically deform the first elastic arm in a direction away from the portion where the first elastic arm is locked, and the second operation component can be configured to pull the second elastic arm to elastically deform the second elastic arm in a direction away from the portion where the second elastic arm is locked. That is, the force acting on the operation component provided by the user can be a pulling force. Therefore, it is understandable that the user can push or pull the operation component to elastically deform the first elastic arm and the second elastic arm in a direction away from the portion where they are locked.

[0072] As shown in FIGS. 3 to 6, the first abutting portion 31a projects from the first operation component 3a along the lateral direction. The second cooperating portion 43b is formed at the free end of the second elastic arm 41b in order to cooperate with the first abutting portion 31a. The first operation component 3a elastically deforms the second elastic arm 41b from the portion 5 where it is locked by the abutment between the first abutting portion 31a and the second cooperating portion 43b in order to disengage the second locking head 42b from the portion 5 where it is locked. The second abutting portion 31b projects from the second operation component 3b along the lateral direction. The first cooperating portion 43a is formed at the free end of the first elastic arm 41a in order to cooperate with the second abutting portion 31b. The second operation component 3b elastically deforms the first elastic arm 41a from the portion 5 where it is locked by the abutment between the second abutting portion 31b and the first cooperating portion 43a in order to disengage the first locking head 42a from the portion 5 where it is locked. Preferably, the first cooperating portion 43a can be aligned with the second abutting portion 31b along the lateral direction, and the second cooperating portion 43b can be aligned with the first abutting portion 31a along the lateral direction, which makes the abutment of the operation component 3 more precise and the unlocking operation of the buckle assembly 100 more labor-saving.

[0073] As shown in FIGS. 3 to 6, the first lock head 42a projects from the inner wall of the first elastic arm 41a along the lateral direction. The first cooperation part 43a is adjacent to the first lock head 42a. The second lock head 42b projects from the inner wall of the second elastic arm 41b along the lateral direction. The second cooperation part 43b is adjacent to the second lock head 42b. Therefore, when the first contact part 31a and the second contact part 31b push the second cooperation part 43b and the first cooperation part 43a respectively, the first elastic arm 41a and the second elastic arm 41b are elastically deformed in a direction away from the locked part 5 in order to quickly disengage the first lock head 42a and the second lock head 42b from the locked part 5. Preferably, the first lock head 42a and the first cooperation part 43a can be sequentially arranged along the direction from the fixed end of the first elastic arm 41a to the free end of the first elastic arm 41a, and the second lock head 42b and the second cooperation part 43b can be sequentially arranged along the direction from the fixed end of the second elastic arm 41b to the free end of the second elastic arm 41b. Since the first cooperation part 43a and the second cooperation part 43b can be arranged at the free ends of the first elastic arm 41a and the second elastic arm 41b respectively, the force acting on the operation component 3 provided by the user to elastically deform the first elastic arm 41a and the second elastic arm 41b can be small.

[0074] Specifically, the first cooperating portion 43a and the second cooperating portion 43b can be arranged at different levels along the vertical direction which can be the direction P shown by the arrow in FIG. 6, and since the first abutting portion 31a and the second abutting portion 31b can be arranged at different levels along the vertical direction, the abutting of the first abutting portion 31a and the second cooperating portion 43b and the abutting of the second abutting portion 31b and the first cooperating portion 43a occur at different levels, which prevents any structural interface during the sliding movement of the first operating component 3a and the second operating component 3b along the lateral direction and guarantees the reliability of the unlocking operation of the buckle assembly 100. In this embodiment, the height of the second abutting portion 31b and the first cooperating portion 43a can be higher than the height of the first abutting portion 31a and the second cooperating portion 43a. However, it is not limited to this embodiment.

[0075] Preferably, the first cooperating portion 43a can be misaligned with the second cooperating portion 43b along the lateral direction, and the first abutting portion 31a does not have to be aligned with the second abutting portion 31b along the lateral direction, so that it can reduce the occupied space along the vertical direction and facilitate the arrangement of the internal space of the buckle assembly 100. In this embodiment, the first abutting portion 31a and the second cooperating portion 43b can be arranged in front of the second abutting portion 31b and the first cooperating portion 43a along the extending direction, the extending direction can be the direction Q shown by the arrow in FIG. 5, and can be perpendicular to the lateral direction and the fitting direction. However, it is not limited to this embodiment.

[0076] In another embodiment, when there is only one locking portion disposed on one side of the portion to be locked for engagement with the portion to be locked, there can be only one operating component disposed on the other side of the portion to be locked opposite the locking portion so as to elastically push the locking portion away from the portion to be locked to disengage the locking portion from the portion to be locked. In other words, the operating component and the locking portion can be disposed on two opposite sides of the portion to be locked so that the operating component pushes the locking portion to disengage the locking portion from the portion to be locked. Alternatively, in another embodiment, the operating component and the locking portion can be disposed on the same side of the portion to be locked to pull the locking portion by the operating component to disengage the locking portion from the portion to be locked.

[0077] As shown in FIGS. 3 to 6, the portion 5 to be locked includes an abutting structure 51 and a locked structure 52 configured to engage with two locking heads, i.e., a first locking head 42a and a second locking head 42b. The abutting structure 51 abuts against the two locking heads to elastically deform two elastic arms, i.e., a first elastic arm 41a and a second elastic arm 41b, and passes across the two locking heads to enable the locked structure 52 to engage with the two locking heads during the fitting process of the first buckle component 1 and the second buckle component 2. The operating component 3 elastically deforms the two elastic arms to disengage the two locking heads from the locked structure 52 during the sliding movement of the operating component 3 with respect to the second buckle component 2. Preferably, the end portion of the abutting structure 51 can include a first inclined portion 511 inclined with respect to the fitting direction. Each locking head includes a second inclined portion 421 for cooperating with the first inclined portion 511. The abutting structure 51 passes the two locking heads through the abutting of the second inclined portion 421 and the first inclined portion 511 of the two locking heads to elastically deform the two elastic arms and engage the locked structure 52 with the two locking heads during the fitting process of the first buckle component 1 and the second buckle component 2. Further, the locked structure 52 can be a sealed recess, and the two locking heads can engage with the sealed recess. However, it is not limited thereto.

[0078] As shown in FIGS. 3 to 5, each elastic component 6 is disposed between the second buckle component 2 and one of the corresponding first operating component 3a and second operating component 3b to urge the corresponding one of the first operating component 3a and second operating component 3b to slide away from the locking portion 4. Therefore, when the first operating component 3a and the second operating component 3b are released, the first operating component 3a and the second operating component 3b can be elastically restored by the two elastic components 6. However, the number of elastic components is not limited to this embodiment. For example, in another embodiment, when there is only one operating component, there may be only one elastic component.

[0079] Specifically, two C-shaped structures 24 are formed on the second buckle component to accommodate the two elastic components 6. The two elastic components 6 are respectively disposed between the first operating component 3a and the second buckle component 2 and between the second operating component 3b and the second buckle component 2.

[0080] As shown in FIGS. 3 to 5, the restraining protrusions 33 protrude from each of the first operating component 3a and the second operating component 3b of the operating component 3. Two restraining blocks 25 are formed on the second buckle component 2 to cooperate with the two restraining protrusions 33. The second buckle component 2 blocks the first operating component 3a and the second operating component 3b of the operating component 3 by the abutment of the two restraining blocks 25 and the two restraining protrusions 33 to prevent the disengagement of the first operating component 3a and the second operating component 3b of the operating component 3 and the second buckle component 2. However, the number of restraining blocks is not limited to this embodiment. For example, in another embodiment, when there is only one operating component, there can be only one restraining block.

[0081] As shown in FIGS. 3 to 5, preferably, the lock portion 4 can be removably connected to the second buckle component 2. Such a configuration allows them to be easily replaced when the lock portion 4 or the second buckle component 2 is damaged, and simplifies the manufacturing process of the buckle assembly 100. Specifically, the lock portion 4 further includes an engagement bracket 44. An engaging structure is formed on the second buckle component 2 for removable engagement with the engagement bracket 44. The engagement bracket 44 is fixedly connected to the fixed ends of the first elastic arm 41a and the second elastic arm 41b, and is removably embedded in the engaging structure. More specifically, the engaging structure includes two engaged rods 22 spaced apart from each other. The engagement bracket 44 is embedded between the two engaged rods 22. Each engaged rod 22 includes an upper restraint portion 221 and a lower restraint portion 222. The upper restraint portion 221 and the lower restraint portion 222 are configured to restrain the movement of the engagement bracket 44. When the engagement bracket 44 is removably embedded in the engaging structure, the engagement bracket 44 is disposed between the upper restraint portion 221 and the lower restraint portion 222. Preferably, the engagement bracket 44 can include two stepped structures 441 that engage with the two lower restraint portions 222 when the engagement bracket 44 is removably embedded in the engaging structure. Such a configuration prevents unintentional disengagement of the lock portion 4 and the two lower restraint portions 222, and allows for reasonable use of the internal space of the second buckle component 2. Preferably, an avoidance space 9 can be formed between the two engaged rods 22 to allow the two elastic arms to move. The two elastic arms project from the avoidance space 9 and can be elastically deformed to move within the avoidance space 9.

[0082] However, the number of engaged rods and stepped structures is not limited to this embodiment. For example, in another embodiment, the engaged structures can include one, three, or more engaged rods, and the engagement brackets can correspondingly include one, three, or more stepped structures.

[0083] As shown in FIGS. 3 to 6, the buckle assembly 100 further includes a first magnetic structure 7 and a second magnetic structure 8. The first magnetic structure 7 is disposed on the first buckle component 1. The second magnetic structure 8 is disposed on the second buckle component 2. The first magnetic structure 7 and the second magnetic structure 8 can magnetically attract each other during the fitting process of the first buckle component 1 and the second buckle component 2, which makes the fitting of the first buckle component 1 and the second buckle component 2 faster. On the other hand, even if the locking portion 4 and the locked portion 5 are disengaged from each other, the first buckle component 1 and the second buckle component 2 are prevented from separating from each other due to the magnetic attraction of the first magnetic structure 7 and the second magnetic structure 8, which guarantees the safety of the buckle assembly 100. However, it is not limited to this embodiment. For example, in another embodiment, the first magnetic structure and the second magnetic structure can be configured to magnetically repel each other during the fitting process of the first buckle component and the second buckle component, which makes the release operation of the buckle assembly 100 faster.

[0084] Specifically, the first embedding chamber 11 is formed in the first buckle component 1. The second embedding chamber 23 is formed in the second buckle component 2. The first magnetic structure 7 is embedded in the first embedding chamber 11. The second magnetic structure 8 is embedded in the second embedding chamber 23. Preferably, the first embedding chamber 11 can be aligned with the second embedding chamber 23 along the fitting direction to enhance the magnetic attraction force between the first magnetic structure 7 and the second magnetic structure 8. However, it is not limited to this embodiment. Specifically, the second embedding chamber 23 can be aligned with the space between the first lock head 42a and the second lock head 42b along the fitting direction as shown in FIG. 6 to achieve a reasonable use of the space of the buckle assembly 100, so that it makes the structure of the buckle assembly 100 more compact.

[0085] As shown in FIGS. 5 and 6, the operating principle of the buckle assembly 100 is provided as follows. When it is desired to release the buckle assembly 100, the first operating component 3a and the second operating component 3b can be pressed or operated to elastically deform the second elastic arm 41b and the first elastic arm 41a respectively by the abutment of the first abutting portion 31a and the second cooperating portion 43b and the abutment of the second abutting portion 31b and the first cooperating portion 43a to disengage the second lock head 42b and the first lock head 42a from the locked portion 5. When the second lock head 42b and the first lock head 42a are disengaged from the locked portion 5, that is, when the buckle assembly 100 is in the released state, the first buckle component 1 can be separated from the second buckle component 2 to place the buckle assembly 100 in the separated state. Then, when the first operating component 3a and the second operating component 3b are released, the two elastic components 6 drive the first operating component 3a and the second operating component 3b to recover.

[0086] When it is desired to engage the first buckle component 1 with the second buckle component 2, the locking structure 52 is aligned with the first locking head 42a and the second locking head 42b as the abutting structure 51 passes through the first locking head 42a and the second locking head 42b, allowing the first elastic arm 41a and the second elastic arm 41b to be elastically deformed. In order for the abutting structure 51 to abut against the first locking head 42a and the second locking head 42b, the portion 5 to be locked can be inserted into the fitting hole 21. When the abutting structure 51 passes through the first locking head 42a and the second locking head 42b and aligns the locked structure 52 with the first locking head 42a and the second locking head 42b, the first locking head 42a and the second locking head 42b are driven by the first elastic arm 41a and the second elastic arm 41b to engage with the locked structure 52.

[0087] Refer to FIGS. 7 to 10. FIG. 7 is a schematic view of a buckle assembly 100' according to a second embodiment of the present invention. FIG. 8 is an exploded view of the buckle assembly 100' according to the second embodiment of the present invention. FIGS. 9 and 10 are views of the buckle assembly 100' in different states according to the second embodiment of the present invention. As shown in FIGS. 7 to 10, the buckle assembly 100' includes a first buckle component 1, a second buckle component 2', an operation component 3, two elastic components 6, a first magnetic structure 7, and a second magnetic structure 8. The structures of the first buckle component 1, the operation component 3, the elastic component 6, the first magnetic structure 7, and the second magnetic structure 8 in this embodiment are similar to those in the first embodiment. For the sake of simplicity, detailed descriptions are omitted here. The second buckle component 2' includes a lock portion 4'. The lock portion 4' includes a first lock portion 4a' and a second lock portion 4b'. The first lock portion 4a' and the second lock portion 4b' are arranged on both sides of the locked portion 5 of the first buckle component 1, and clamp the locked portion 5 along a lateral direction that can be the arrow direction M1 or M2 shown in FIGS. 9 and 10. The first operation component 3a of the operation component 3 and the first lock portion 4a' are arranged on the same side. The first lock portion 4a' is configured to cooperate with the second operation component 3b of the operation component 3. The second operation component 3b of the operation component 3 and the second lock portion 4b' are arranged on another same side. The second lock portion 4b' is configured to cooperate with the first operation component 3a of the operation component 3.

[0088] Specifically, the first locking portion 4a' includes a first rotating arm 41a' and a first locking head 42a'. The first locking head 42a' is configured to engage with the portion 5 to be locked. The first rotating arm 41a' is pivotally connected to the second buckle component 2' by a first pivoting portion 411a'. A first cooperating portion 43a' is formed on the first rotating arm 41a' for cooperating with a second abutting portion 31b of the second operating component 3b. The first cooperating portion 43a' is aligned with the second abutting portion 31b along the lateral direction. The first locking head 42a' is connected to the first rotating arm 41a' and protrudes from the inner wall of the first rotating arm 41a' along the lateral direction. The second locking portion 4b' includes a second rotating arm 41b' and a second locking head 42b'. The second locking head 42b' is configured to engage with the portion 5 to be locked. The second rotating arm 41b' is pivotally connected to the second buckle component 2' by a second pivoting portion 411b'. A second cooperating portion 43b' is formed on the second rotating arm 41b' for cooperating with a first abutting portion 31a of the first operating component 3a. The second cooperating portion 43b' is aligned with the first abutting portion 31a along the lateral direction. The second locking head 42b' is connected to the second rotating arm 41b' and protrudes from the inner wall of the second rotating arm 41b' along the lateral direction.

[0089] In this embodiment, the first cooperating portion 43a' and the second cooperating portion 43b' can be arranged at different levels along the vertical direction, and the first cooperating portion 43a' can be misaligned with the second cooperating portion 43b' along the lateral direction, which prevents any structural interface during the unlocking operation of the buckle assembly 100' and guarantees the reliability of the unlocking operation of the buckle assembly 100', and enables a reasonable use of the internal space of the buckle assembly 100'. Preferably, in this embodiment, the first pivoting portion 411a' and the second pivoting portion 411b' can be two slot structures for allowing two pivoting shafts of the second buckle component 2' to pass through.

[0090] Furthermore, the first locking portion 4a' further includes a first restoring component 44a'. The second locking portion 4b' further includes a second restoring component 44b'. The first restoring component 44a' is disposed between the first rotating arm 41a' and the second buckle component 2' to rotate the first rotating arm 41a' to urge it to engage with the portion 5 where the first locking head 42a' is locked along the lateral direction. The second restoring component 44b' is disposed between the second rotating arm 41b' and the second buckle component 2' to rotate the second rotating arm 41b' to urge it to engage the second locking head 42b' with the locking portion 5 along the lateral direction. Preferably, in this embodiment, the first restoring component 44a' and the second restoring component 44b' can be two compression springs. However, it is not limited thereto. For example, in another embodiment, the first restoring component and the second restoring component can be two torsion springs.

[0091] When it is desired to release the buckle assembly 100', the first operating component 3a and the second operating component 3b of the operating component 3 cause the second locking head 42b' and the first locking head 42a' to be disengaged from the second locking portion 5 by elastically compressing the second restoring component 44b' and the first restoring component 44a'. Thus, the first contact portion 31a of the first operating component 3a contacts the second cooperating portion 43b' of the second locking portion 4b', and the second contact portion 31b of the second operating component 3b contacts the first cooperating portion 43a' of the first locking arm 4a', driving the second rotating arm 41b' and the first rotating arm 41a' respectively to be pressed or operated. When the second locking head 42b' and the first locking head 42a' are released from the portion 5 where they are locked, that is, when the buckle assembly 100' is in the released state, the first buckle component 1 can be separated from the second buckle component 2' to place the buckle assembly 100' in a separated state. Then, when the first operating component 3a and the second operating component 3b are released, the two elastic components 6 drive and restore the first operating component 3a and the second operating component 3b.

[0092] When it is desirable to engage the first buckle component 1 with the second buckle component 2', in order for the abutting structure 51 to pass through the first lock head 42a' and the second lock head 42b', the abutting structure 51 abuts against the first lock head 42a' and the second lock head 42b' to rotate the first rotating arm 41a' and the second rotating arm 41b', and to elastically compress the first restoring component 44a' and the second restoring component 44b', the locking portion 5 can be inserted into the fitting hole of the second buckle component 2'. When the abutting structure 51 passes through the first lock head 42a' and the second lock head 42b' and aligns the locking structure 52 with the first lock head 42a' and the second lock head 42b', the first lock head 42a' and the second lock head 42b' can be driven by the first restoring component 44a' and the second restoring component 44b' to engage with the locking structure 52.

[0093] In other embodiments, when there is only one locking portion disposed on one side of the portion to be locked to engage with the portion to be locked, it can be understood that there can be only one operating component disposed on the other side of the portion to be locked opposite to the locking portion to elastically push the locking portion away from the portion to be locked in order to disengage the locking portion from the portion to be locked. In other words, the operating component and the locking portion can be disposed on two opposite sides of the portion to be locked to push the locking portion by the operating component in order to disengage the locking portion from the portion to be locked. Alternatively, in another embodiment, the operating component and the locking portion can be disposed on the same side of the locking portion to pull the locking portion by the operating component in order to disengage the portion to be locked from the locking portion.

[0096] Furthermore, the first locking portion 4a” further includes a first restoring component 44a”. The second locking portion 4b” further includes a second restoring component 44b”. The first restoring component 44a” is disposed between the first rotating arm 41a” and the second buckle component 2” to urge the first rotating arm 41a” to engage with the portion 5 where the first locking head 42a” is locked along the lateral direction. The second restoring component 44b” is disposed between the second rotating arm 41b” and the second buckle component 2” to urge the second rotating arm 41b” to engage with the portion 5 where the second locking head 42b” is locked along the lateral direction. Preferably, in this embodiment, the first restoring component 44a” and the second restoring component 44b” can be two compression springs. However, it is not limited thereto. For example, in another embodiment, the first restoring component and the second restoring component can be two torsion springs.

[0097] When it is desired to release the buckle assembly 100, the operation component 3” is pushed or operated to elastically compress the first restoring component 44a” and the second restoring component 44b” in order to disengage the first locking head 42a” and the second locking head 42b” from the portion 5 where they are locked. By the abutment of the first cooperating portion 43a” of the first locking portion 4a” and the second abutting portion 31b” and the abutment of the second cooperating portion 43b” of the second locking portion 4b” and the first abutting portion 31a”, the first rotating arm 41a” and the second rotating arm 41b” can be respectively driven.
