Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and in particular to a protective case. Background Technology

[0002] Current smart wearable devices, such as smart glasses, and glasses or helmets corresponding to virtual reality (VR), augmented reality (AR), and mixed reality (MR), are usually equipped with a protective case for easy portability. Common protective cases are generally designed with a flip-top magnetic closure, which makes it easy to open when the protective case is squeezed or dropped. Summary of the Invention

[0003] The main objective of this invention is to propose a protective box that improves the opening and closing structure of the protective box, enabling it to be firmly locked while being able to be opened quickly, thereby improving the protective performance of smart wearable devices.

[0004] To achieve the above objectives, the present invention provides a protective box, comprising: The box has an open-top cavity for receiving the contents. The box is provided with a first locking member, which is movable in the horizontal or vertical direction. The first locking member has a locking position and an unlocking position. A cover for closing the receiving cavity, the cover being rotatably mounted on the housing at one longitudinal end, and a second locking member at the other longitudinal end, the second locking member engaging with a first locking member in the locked position to close the cover; and... The unlocking structure includes a driving member and a limiting member movably mounted to the housing. One end of the driving member protrudes from the housing, and the other end of the driving member engages with a second locking member. The driving member has a first position and a second position. In the first position, the driving member can be pressed to move the first locking member to the unlock position. In the second position, the driving member is fixed relative to the housing and limits the first locking member to the unlock position, so that the cover can be opened. The limiting member is used to fix the driving member in the second position. When the first locking member is in the locked position, it can cooperate with the second locking member; when the first locking member is in the unlocked position, it is offset from the second locking member in the horizontal or vertical direction.

[0005] In one embodiment, the cover has a through hole; The driving member is located at the upper end of the box and extends in the vertical direction. When the cover is closed and the driving member is in the first position, one end of the driving member can extend into the through hole. When the driving member is in the second position, one end of the driving member is separated from the through hole.

[0006] In one embodiment, at least one of the first locking member and the second locking member is configured as a resilient mounting member, capable of moving under external force and resiliently returning to its original position; and / or, The other end of the drive component engages with the first locking component via an inclined surface, and the first locking component is connected to the box body on one longitudinal side via a first elastic element.

[0007] In one embodiment, the second locking member has a snap-fit ​​groove on one side along the longitudinal direction, and the lower end of the second locking member has a first mating inclined surface extending from bottom to top toward the snap-fit ​​groove. The first locking member is provided with a longitudinally extending locking protrusion corresponding to the locking groove, and the upper side of the locking protrusion is provided with a second mating slope corresponding to the first mating slope.

[0008] In one embodiment, the limiting member is located on the side of the first locking member and has a travel distance that moves closer to or further away from the first locking member; When the drive member is in the second position, the limiting member abuts against the first locking member to limit the first locking member to the unlocked position.

[0009] In one embodiment, the limiting member includes: The main body, the side of which faces away from the second locking member, is connected to the box body via a second elastic member; Two extension arms are provided on the same side of the main body and are spaced apart longitudinally. One of the extension arms cooperates with the first locking member, and the other extension arm cooperates with the first locking member through an inclined surface. After the cover moves the first locking member to contact the corresponding extension arm, it can drive the limiting member to move away from the first locking member, so that the other extension arm separates from the first locking member.

[0010] In one embodiment, the end of the extension arm that cooperates with the first locking member has a first inclined section on both sides in the vertical direction, and the two first inclined sections are inclined towards each other in the direction away from the main body. The second locking member forms two second inclined sections corresponding to the two first inclined sections.

[0011] In one embodiment, the sides of the limiting member and the first locking member that cooperate with each other are both stepped, so that a protrusion and a recess are formed on the limiting member and the first locking member respectively. During the movement of the first locking member, the protrusion of the limiting member can be embedded in the recess of the first locking member, or the protrusion of the limiting member abuts against the protrusion of the first locking member.

[0012] In one embodiment, two second locking members are provided and are spaced apart laterally; The first locking member is movably mounted on the housing along the longitudinal direction, and the first locking member cooperates with two second locking members at both ends of the longitudinal direction. Two limiting members are provided, and the two limiting members are respectively located on opposite sides of the first locking member along the longitudinal direction.

[0013] In one embodiment, the protective box further includes two magnetically attached parts, which are correspondingly disposed on the cover and the box body.

[0014] In the technical solution of this invention, the cover and the box body rotate together. The cover is locked in its natural state by the cooperation of a first locking member and a second locking member. Based on the cooperation relationship between the driving member and the first locking member, after the user manually presses the driving member, the first locking member can be moved away from the second locking member, that is, from the locked position to the unlocked position. The user can then manually pry the cover open, which is simple to operate. Through the cooperation of the limiting member and the driving member, after the user presses the driving member to unlock the cover, the driving member will still be restricted to the second position by the limiting member after releasing the driving member. That is, the driving member will not restrict the user's action of prying open the cover. In this structure, unlocking is achieved by manually pressing the driving member, thus maintaining the stability of the locked state in its natural state. Even if the protective box is squeezed or dropped, the cover will not pop open, thereby improving the protection of smart wearable devices and providing a good anti-loss effect. The press-to-unlock action is simple, enabling the protective box to be firmly locked while also allowing for quick opening. Attached Figure Description

[0018] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that if the embodiments of the present invention involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0021] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0022] Current smart wearable devices, such as smart glasses, and glasses or helmets corresponding to virtual reality (VR), augmented reality (AR), and mixed reality (MR), are usually equipped with a protective case for easy portability. Common protective cases are generally designed with a flip-top magnetic closure, which makes it easy to open when the protective case is squeezed or dropped.

[0023] In view of this, the present invention proposes a protective box that can be firmly locked while being able to be quickly opened, thereby improving the protection performance of smart wearable devices.

[0024] Please refer to Figure 1 , Figure 2 and Figure 5 The protective box 100 includes a box body 1, a cover 2, and an unlocking structure 3. The box body 1 has an open-top cavity 11 and a first locking member 12. The first locking member 12 is movable in the horizontal or vertical direction and has a locked position and an unlocked position. The cover 2 is used to cover the cavity 11. The cover 2 is rotatably mounted on the box body 1 at one vertical end and has a second locking member 21 at the other vertical end. The second locking member 21 can cooperate with the first locking member 12 in the locked position to close the cover 2. The unlocking structure 3 includes a driving member 31 and a limiting member 32 movably mounted to the box body 1. One end of the drive member 31 protrudes from the box body 1, and the other end of the drive member 31 cooperates with the second locking member 21. The drive member 31 has a first position and a second position. In the first position, the drive member 31 can be pressed to move the first locking member 12 to the unlock position. In the second position, the drive member 31 is fixed relative to the box body 1 and the first locking member 12 is limited to the unlock position so that the cover 2 can be opened. The limiting member 32 is used to fix the drive member 31 in the second position. When the first locking member 12 is in the locked position, it can cooperate with the second locking member 21. When the first locking member 12 is in the unlock position, it is offset from the second locking member 21 in the horizontal or vertical direction.

[0025] In the technical solution of this invention, the smart wearable device is housed within the receiving cavity 11. The cover 2 rotates with the box body 1. The cover 2 is locked in its natural state through the cooperation of the first locking member 12 and the second locking member 21. Based on the cooperation relationship between the driving member 31 and the first locking member 12, after the user manually presses the driving member 31, it can drive the first locking member 12 to move away from the second locking member 21, that is, change from the locked position to the unlocked position. The user can then manually pry open the cover 2, which is simple to operate. Through the cooperation of the limiting member 32 and the driving member 31, after the user presses the driving member 31 to unlock the cover 2, the driving member 31 will still be restricted to the second position by the limiting member 32 after releasing the driving member 31. That is, the driving member 31 will not restrict the user's action of prying open the cover 2. In this structure, unlocking is achieved by manually pressing the drive component 31, thus maintaining a stable locked state in its natural state. Even when the protective case 100 is squeezed or dropped, the cover 2 will not pop open, thereby improving the protection of smart wearable devices and providing a good anti-loss effect. The press-to-unlock action is simple, allowing the protective case 100 to be securely locked while also being able to be opened quickly.

[0026] In its natural state, the drive member 31 is in the first position, with its end protruding from the housing 1. The first locking member 12 and the second locking member 21 cooperate to keep the cover 2 locked. At this time, the first locking member 12 is in the locked position. When it is necessary to open the cover 2, the user needs to manually press the end of the drive member 31 protruding from the housing 1, which will cause the other end of the drive member 31 to move, allowing the drive member 31 to switch from the first position to the second position. During this process, the drive member 31 drives the first locking member 12 to move away from the second locking member 21, allowing the first locking member 12 to move away from the second locking member 21. When the first locking member 12 changes from the locked position to the unlocked position, the driving member 31 reaches the second position after the first locking member 12 reaches the unlocked position. The driving member 31 is fixed in the second position by the limiting member 32, so that the first locking member 12 is limited in the unlocked position, thereby maintaining a positional state that is offset from the second locking member 21 in the horizontal or vertical direction. Since the first locking member 12 and the second locking member 21 are separated from each other, the restriction on the cover 2 is released. Since the driving member 31 is limited in the second position, even if the user releases the driving member 31, the cover 2 can be turned to open it.

[0027] The direction of movement of the first locking member 12 is determined by the cooperation form of the first locking member 12 and the second locking member 21. If the ends of the two locking members are arranged opposite each other in the lateral direction, the first locking member 12 needs to move in the lateral direction. If the ends of the two locking members are arranged opposite each other in the longitudinal direction, the first locking member 12 needs to move in the longitudinal direction.

[0028] The driving component 31 is used as a button, and its shape is not limited. The driving component 31 can move in the vertical direction and is correspondingly set at the upper end of the box 1. The driving component 31 can also move in the vertical direction and is correspondingly set on the side surface of the box 1.

[0029] The cover 2 and the box 1 can be connected by a rotating shaft, or they can be rotated together by a flange and an arc groove. It should be understood that in this embodiment, no spring structure is provided at the rotating connection between the cover 2 and the box 1. Therefore, after the cover 2 is unlocked, it cannot automatically pop open and needs to be opened manually by the user.

[0030] In other embodiments, a torsion spring can be designed at the rotatable connection between the cover 2 and the box 1 so that the cover 2 can automatically spring open after being unlocked. In this case, when designing the first locking member 12 and the second locking member 21, the connection force after the two are engaged needs to overcome the elastic force of the torsion spring.

[0031] To facilitate opening the lid 2, a notch 15 is provided on the upper side of the box 1. When it is necessary to open the lid 2, the user can use the notch 15 to open it, making the lid 2 open more smoothly. It should be understood that the notch 15 should extend horizontally and have a certain depth vertically, so that the user's fingers can touch the edge of the lid 2 through the notch 15 for easy application of force.

[0032] Please refer to Figure 2 The cover 2 has a through hole 22, which should be spaced apart from the second locking member 21; the driving member 31 is located at the upper end of the box 1 and extends in the vertical direction. When the driving member 31 is in the first position, please combine... Figure 1 When the cover 2 is closed, the upper end of the drive member 31 can extend into the through hole 22. The through hole 22 serves to avoid the drive member 31. At this time, the drive member 31, in conjunction with the through hole 22, also helps to limit the cover 2 when it is closed, preventing it from wobbling laterally and longitudinally. When the drive member 31 is pressed into the second position, please combine... Figure 12 At this time, the upper end of the drive member 31 sinks to the lower side of the cover 2 and separates from the through hole 22. In this embodiment, when the cover 2 is closed, the upper end surface of the drive member 31 is flush with or lower than the cover 2, making it less likely for the upper end of the drive member 31 to be accidentally touched, thus improving safety performance.

[0033] By reasonably setting the length of the drive component 31 and the thickness of the cover 2, the drive component 31 can be easily pressed by the user even when it is inside the through hole 22.

[0034] During the entire cooperation process, the following cooperation states exist: The cover 2 is locked to cover the receiving cavity 11: the first locking member 12 is in the locked position and cooperates with the second locking member 21, the driving member 31 is in the first position, the limiting member 32 does not limit the driving member 31, and the driving member 31 is in the first position. The cover 2 is unlocked, but still covers the receiving cavity 11: the first locking member 12 is in the unlocked position and is offset from the second locking member 21 in the horizontal or vertical direction, and the driving member 31 is limited to the second position by the limiting member 32. The cover 2 is fully opened to reveal the smart wearable device inside the cavity 11: the first locking member 12 is in the locked position, the driving member 31 is in the first position, and the limiting member 32 does not limit the driving member 31.

[0035] In the above process, the first locking member 12 needs to satisfy the following: when the cover 2 is closed, it can lock with the second locking member 21; when the cover 2 needs to be opened, it can separate from the second locking member 21; and when the cover 2 changes from open to closed, it can re-lock with the second locking member 21.

[0036] In some embodiments, at least one of the first locking member 12 and the second locking member 21 is configured as an elastic mounting member, capable of moving under external force and elastically returning to its original position. For example, at least one of the first locking member 12 and the second locking member 21 can be connected by a spring, so that the corresponding locking member can move under external force to compress the spring and can elastically return to its original position under the spring's rebound force, thereby meeting the requirements of an elastic mounting member. For example, at least one of the first locking member 12 and the second locking member 21 can be configured as an elastic snap. The elastic snap can be deformed at least partially under external force, thereby switching between a snap-fit ​​state and a snap-unfit state. In this embodiment, after the cover 2 is opened, the first locking member 12 is in the locked position. When the cover 2 needs to be closed, the first locking member 12 remains in the locked position. At this time, the second locking member 21 contacts the first locking member 12, and the corresponding locking member can be moved or deformed under external force due to the elastic mounting form, thereby re-establishing the locking engagement. This configuration method has a simple structure, involves few parts, and occupies little space.

[0037] It should be understood that either the first locking member 12 or the second locking member 21 can be a resilient mounting member, or both the first locking member 12 and the second locking member 21 can be resilient mounting members.

[0038] This invention does not limit the cooperation form between the first locking member 12 and the driving member 31. In some embodiments, the other end of the driving member 31 is engaged with the first locking member 12 via an inclined surface, and the longitudinal side of the first locking member 12 is connected to the housing 1 via a first elastic member 13. Taking the vertical movement of the driving member 31 as an example, based on the inclined surface cooperation, the driving force of the driving member 31 in the vertical direction can be decomposed into a longitudinal force, thereby driving the first locking member 12 to move longitudinally and compress the first elastic member 13. When the external force on the driving member 31 is released, under the action of the rebound force of the first elastic member 13, the first locking member 12 moves back to its original position, which can drive the driving member 31 to move upward and reset. This structural form occupies little space and can realize the direction conversion of the driving force. When the driving member 31 moves longitudinally, the first locking member 12 is correspondingly driven to move vertically or laterally, depending on the orientation of the inclined surfaces of the two.

[0039] Specifically, in this embodiment, please refer to Figure 6 and Figure 10The driving member 31 is provided with a first driving inclined surface 311, which extends from bottom to top toward the first locking member 12. Correspondingly, the first locking member 12 is provided with a first driving mating inclined surface 123, which extends from bottom to top away from the driving member 31 so as to fit against the first driving inclined surface 311. It should be understood that the first driving inclined surface 311 and the first driving mating inclined surface 123 should always remain in contact with each other. When the driving member 31 is pressed down, the first locking member 12 is driven to move longitudinally in a direction away from the driving member 31. The first elastic member 13 can be set as a spring, a sheet, a rubber band, etc., and the present invention does not limit it. Depending on the size of the first locking member 12, multiple first elastic members 13 can be provided.

[0040] In other embodiments, the other end of the driving member 31 and the first locking member 12 can also be connected by a linkage or gear structure, and the present invention does not limit this.

[0041] In this embodiment, the second locking member 21 is set as an elastic buckle, and the first locking member 12 is engaged with the inclined surface of the driving member 31, so that it can be driven to change from the locked position to the unlocked position. The first locking member 12 is connected to the box body 1 through a spring, so that it can return to the locked position from the reset position by relying on the rebound force.

[0042] Please refer to Figure 4 , Figure 9 and Figure 14 The second locking member 21 has a locking groove 211 on one longitudinal side, and a first mating inclined surface 212 extending from bottom to top toward the locking groove 211 at its lower end. The first locking member 12 has a locking protrusion 121 extending longitudinally corresponding to the locking groove 211, and a second mating inclined surface 122 corresponding to the first mating inclined surface 212 on its upper side. When the cover 2 is closed, the locking protrusion 121 can be engaged in the locking groove 211. When the first locking member 12 is driven to move longitudinally, the locking protrusion 121 can be disengaged from the locking groove 211. During the process of the cover 2 changing from the open state to the closed state, the second locking member 21 moves downward, so that the first mating inclined surface 212 and the second mating inclined surface 122 contact first. The inclined surface mating form can convert the downward driving force of the second locking member 21 into a driving force in the longitudinal direction. When one of the first locking member 12 and the second locking member 21 is an elastic buckle, the longitudinal driving force will cause the elastic buckle to deform and thus change position, so that the buckle protrusion 121 can be re-clamped in the buckle groove 211. When the first locking member 12 is connected to the box 1 through the first elastic member 13, the longitudinal driving force will cause the first elastic member 13 to compress a certain distance, so that as the second locking member 21 continues to move downward, the buckle protrusion 121 can be re-clamped in the buckle groove 211.

[0043] In the technical solution of this application, the second locking member 21 is set as an elastic buckle, and the first locking member 12 is connected by the first elastic member 13. At this time, the second locking member 21 and the first locking member 12 can be displaced in a direction far greater than each other.

[0044] The limiting member 32 can be a fixed member, which can cooperate with the limiting member 32 when the driving member 31 moves to the designated position, thereby being fixed in the second position. The limiting member 32 can also be a movable member, which can lock the position of the driving member 31 and release the locking of the position of the driving member 31 by driving the limiting member 32 to move actively.

[0045] In this embodiment, please refer to Figure 5 and Figure 13 The limiting member 32 is located to the side of the first locking member 12 and has a travel range that allows it to move closer to or further away from the first locking member 12. When the driving member 31 is in the second position, the limiting member 32 abuts against the first locking member 12 to limit the first locking member 12 to the unlocked position. That is, the displacement of the limiting member 32 allows it to hold and fix the first locking member 12, thereby indirectly limiting the driving member 31 to the second position. Driving the limiting member 32 to move in the opposite direction can release the position restriction on the first locking member 12. It should be noted that the driving of the limiting member 32 can be either active or passive.

[0046] The method of abutting and fixing the limiting member 32 and the first locking member 12 is not limited. It can be that the structure at the end of the limiting member 32 can block the movement direction of the first locking member 12 when it abuts against it, or a positioning pin and a positioning hole can be provided on the side where the first locking member 12 and the limiting member 32 cooperate, and the position can be limited by the form of pin hole insertion.

[0047] Please refer to Figure 5 and Figure 13 The sides of the limiting member 32 and the first locking member 12 that cooperate with each other are both stepped, so that a protrusion 10 and a recess 20 are formed on the limiting member 32 and the first locking member 12 respectively. During the movement of the first locking member 12, when the protrusion 10 of the limiting member 32 is embedded in the recess 20 of the first locking member 12 (please refer to...) Figure 13 The two are riveted together, at which point the first locking member 12 is restricted to the unlocked position and cannot move further; when the protrusion 10 of the limiting member 32 abuts against the protrusion 10 of the first locking member 12 (please refer to...) Figure 5At this point, the limiting member 32 only contacts and engages with the first locking member 12, but does not obstruct the movement of the first locking member 12. The first locking member 12 can move relative to the limiting member 32 along its movement trajectory. It should be understood that when the movement stroke of the first locking member 12 is less than the thickness of the protrusion 10 of the limiting member 32, the two maintain the current engagement state; when the movement stroke of the first locking member 12 is greater than the thickness of the protrusion 10 of the limiting member 32, the two return to the locked and limited state.

[0048] For further details, please refer to Figure 7 and Figure 11 The limiting member 32 includes a main body 321 and two extension arms 322. The side of the main body 321 facing away from the second locking member 21 is connected to the box body 1 through the second elastic member 33. The two extension arms 322 are located on the same side of the main body 321 and are spaced apart longitudinally. One extension arm 322 cooperates with the first locking member 12, and the other extension arm 322 cooperates with the first locking member 12 through an inclined surface. After the cover 2 moves the first locking member 12 to contact the corresponding extension arm 322, it can drive the limiting member 32 to move away from the first locking member 12, so that the other extension arm 322 is separated from the first locking member 12. The limiting member 32 is U-shaped, which can accommodate the positional differences of the first locking member 12 and the second locking member 21. In this structure, the limiting member 32 can cooperate with the first locking member 12 to limit the first locking member 12 to the unlocked position and the driving member 31 to the second position. The limiting state of the tight fit is maintained by the elastic force of the second elastic member 33. The limiting member 32 can also be driven by the second locking member 21 to move away from the first locking member 12, thereby separating from the second locking member 21 and releasing the positional limitation on the second locking member 21 and the driving member 31, so that the second locking member 21 and the driving member 31 can be reset.

[0049] Specifically, inclined surfaces are provided on the sides of the second locking member 21 and the corresponding extension arm 322 facing each other. Two second inclined surface segments 213 are formed on the second locking member 21, positioned opposite each other in the vertical direction. The upward-facing second inclined surface segment 213 slopes outward from top to bottom, while the downward-facing second inclined surface segment 213 slopes in the opposite direction. The two second inclined surface segments 213 are located on the same side of the second locking member 21 and slope towards each other. Two first inclined surface segments 322a are provided on the limiting member 32, positioned opposite each other in the vertical direction, with opposite slope directions. Specifically, the end of the extension arm 322, which cooperates with the first locking member 12, forms two first inclined surface segments 322a on both sides in the vertical direction. The two first inclined surface segments 322a slope towards each other in the direction away from the main body 321. This inclined surface cooperation allows for both reversal of driving force and guidance.

[0050] When cover 2 is closed, please combine Figure 5 At this time, the first locking member 12 and the second locking member 21 are engaged, and the protrusion 10 on one of the extension arms 322 abuts against the protrusion 10 on the first locking member 12, and the upward-facing second inclined section 213 abuts against the downward-facing first inclined section 322a.

[0051] When cover 2 needs to be opened, please combine with... Figure 13 Pressing the drive member 31 downwards causes the first locking member 12 to move away from the second locking member 21. The limiting member 32, under the elastic force, always tends to move towards the first locking member 12. When the protrusion 10 of the corresponding extension arm 322 is engaged with the recess 20 of the first locking member 12, the first locking member 12 and the second locking member 21 move away from each other, and the first locking member 12 and the drive member 31 remain fixed. At this time, the user can lift the cover 2. During the process of lifting the cover 2, the second locking member 21 moves upwards. With the cooperation of the upward-facing second inclined section 213 and the downward-facing first inclined section 322a, the upward force of the second locking member 21 is converted into a driving force for the limiting member 32 to move away from the first locking member 12, so that the second elastic member 33 is compressed. The protrusion 10 of the limiting member 32 disengages from the recess 20 in the first locking member 12. At the same time as the second locking member 21 disengages from the box 1, the first locking member 12 resets.

[0052] When the cover 2 needs to be closed again, the second locking member 21 extends into the box 1, and the downward-facing second inclined section 213 contacts the upward-facing first inclined section 322a. During the downward movement of the second locking member 21, the limiting member 32 is driven to move away from the second locking member 21, so as not to interfere with the first locking member 12.

[0053] Furthermore, two second locking members 21 are provided and spaced apart laterally; the first locking member 12 is movably mounted on the box body 1 longitudinally, and the first locking member 12 cooperates with the two second locking members 21 at both ends of the longitudinal direction; two limiting members 32 are correspondingly provided, and the two limiting members 32 are respectively located on opposite sides of the first locking member 12 along the longitudinal direction. This provides a more stable locking force for the cooperation between the box body 1 and the cover body 2, and pressing the driving member 31 can drive the two second locking members 21 to unlock simultaneously.

[0054] Please refer to Figure 8 The two ends of the first locking member 12 are bent towards the second locking member 21 to accommodate the orientation of the components. The driving member 31 is connected to the middle of the second locking member 21. Two first elastic members 13 are provided, corresponding to the two ends of the first locking member 12. At this time, both ends of the first locking member 12 are provided with locking protrusions 121, which cooperate with the locking grooves 211 of the two second locking members 21.

[0055] In this embodiment, the box body 1 also has an installation cavity spaced apart from the receiving cavity 11. The installation cavity and the receiving cavity 11 are independent of each other. A through hole 14 is provided on the upper side of the box body 1 to connect the installation cavity. In the locked position, the first locking member 12 corresponds to the through hole 22, and the second locking member 21 can extend into the through hole 14 to cooperate with the first locking member 12.

[0056] To facilitate the installation and positioning of the drive component 31, a mounting hole spaced apart from the through hole 14 is provided on the upper wall of the mounting cavity. A limiting protrusion 312 is provided at the lower end of the drive component 31 as a whole, and the upper end of the drive component 31 extends out of the mounting hole. The limiting protrusion 312 abuts against the cavity wall of the mounting cavity to prevent the limiting component 32 from falling out. An avoidance groove 313 is provided on the side wall of the limiting component 32. The avoidance groove 313 is provided through two longitudinally opposite side walls to allow partial penetration of the first locking component 12, thereby accommodating the shape and height of the first locking component 12.

[0057] Furthermore, the protective box 100 also includes two magnetically attached parts 4, which are respectively disposed on the cover 2 and the box body 1. When the user closes the cover 2, the two magnetically attached parts 4 attract each other, thereby pulling the cover 2 into contact with the box body 1 through magnetic force, improving the ease of closing the cover 2. It should be noted that when the user opens the cover 2, they need to overcome the magnetic force of the magnetically attached parts 4. The attractive force of the two magnetically attached parts 4 should be reasonably set so that the force experienced by the first locking member 12 and the second locking member 21 during unlocking can overcome the attractive force of the two magnetically attached parts 4.

[0058] Specifically, in this embodiment, the two magnetic suction parts 4 form a mating group, and two mating groups are provided. The two mating groups are located on both sides of the two second locking members 21 that are far away from each other.

[0059] Furthermore, corresponding guide structures, such as guide posts and guide grooves, can be set on the housing 1 to cooperate with the first locking member 12 and the limiting member 32, thereby ensuring that the first locking member 12 and the limiting member 32 are guided linearly based on elastic cooperation, and ensuring the cooperation accuracy.

[0060] In the technical solution of this invention, the first locking member 12 and the second locking member 21 are locked together by the latching protrusion 121 and the latching groove 211, so that the cover 2 and the box 1 are securely locked together. Magnetic suction parts 4 are correspondingly provided on the cover 2 and the box 1, with the two magnetic suction parts 4 being positioned opposite each other but having opposite magnetic pole directions, generating mutual magnetic attraction. The driving member 31 is configured as a button, and the first driving inclined surface 311 on the driving member 31 can cooperate with the first driving mating inclined surface 123 on the first locking member 12. The first locking member 12 and the limiting member 32 are engaged by a step. A first elastic member 13 is provided on the rear side of the first locking member 12 to provide elastic restoring force for the first locking member 12 and the driving member 31. A second elastic member 33 is provided on the rear side of the limiting member 32 to provide elastic restoring force for the limiting member 32.

[0061] refer to Figure 1 , Figure 4 , Figure 5 The cover 2 and the box 1 are already closed together. The corresponding two magnetic parts 4 are tightly attached to the locking groove 211 of the locking device 121. When it is necessary to open the cover 2, press the driving member 31. The interaction between the first driving inclined surface 311 on the driving member 31 and the first driving engagement inclined surface 123 on the first locking member 12 causes the first locking member 12 to move backward and compress the first elastic member 13. This causes the locking protrusion 121 on the first locking member 12 to be misaligned with the locking groove 211 on the second locking member 21. When the driving member 31 is pressed and the first locking member 12 is retracted to a certain distance, the first locking member 12 no longer blocks the movement of the limiting member 32. The limiting member 32 moves towards the first locking member 12 under the elastic force of the second elastic member 33. At this time, the protrusion 10 on the limiting member 32 engages with the recess 20 on the first locking member 12, preventing the first locking member 12 from resetting. At this time, the latching protrusion 121 on the first locking member 12 and the latching groove 211 on the second locking member 21 are completely misaligned. The latching protrusion 121 loses its hooking function and can overcome the magnetic attraction between the corresponding two magnetic suction parts 4, so the user can lift the cover 2.

[0062] refer to Figure 7 , Figure 13 As shown in the structure, when the cover 2 together with the second locking member 21 is lifted, the second inclined section 213 on the second locking member 21 interacts with the first inclined section 322a on the limiting member 32, causing the limiting member 32 to move and compress the second elastic member 33; when the limiting member 32 moves a certain distance, the protrusion 10 on the limiting member 32 separates from the recess 20 on the first locking member 12 and no longer functions, and the first locking member 12 returns to its original position under the elastic force of the first elastic member 13.

[0063] refer to Figure 14 , Figure 15As shown in the structure, when the cover 2 needs to be closed, when the cover 2 is flipped to a certain small angle, the magnetic attraction between the magnetic part 4 on the cover 2 and the magnetic part 4 on the box 1, plus the weight of the cover 2 itself, causes the cover 2, together with the second locking member 21, to drive the first locking member 12 to move. At this time, the first mating inclined surface 212 and the second mating inclined surface 122 abut against each other, and the second locking member 21 continues to move downward until the snap-fit ​​groove 211 on the second locking member 21 engages with the snap-fit ​​protrusion 121 on the first locking member 12, thereby achieving the effect of automatic locking. During the closing process of the cover 2, the first locking member 12 is limited in its movement stroke due to the compression of the first elastic member 13 by the inclined surface, and will not trigger the limiting effect of the limiting member 32. That is, the movement stroke of the first locking member 12 at this time is less than the longitudinal dimension of the protrusion 10 of the limiting member 32.

[0064] It should be understood that the aforementioned mating structure, the corresponding drive stroke and reset stroke should be interconnected, thus ensuring the continuity and stability of the overall mating.

[0065] In the technical solution of the present invention, the design of pressing and elastic cooperation is used to ensure the locking strength between the cover 2 and the box 1 while also allowing the cover 2 to be opened quickly and conveniently; and by using the principle of mutual attraction between the magnetic poles of the two magnetic parts 4, the cover 2 is provided with an auxiliary fixing force when closed, and the cover 2 can also be automatically fastened during the transition from open to closed.

[0066] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
