Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a locking mechanism and a charger. Background Technology

[0002] A charger is a device used to power external electronic devices. It connects electrically to the electronic device through its power port to charge it, or it allows the battery of the electronic device to be removed and placed inside the charger for charging. Therefore, the charger housing needs an opening for the battery to pass through. The housing is typically divided into a first housing and a second housing. The relative movement of the first and second housings opens or closes this opening, facilitating the insertion or removal of the battery. The first and second housings must be equipped with a locking mechanism for secure insertion and removal.

[0003] However, existing chargers typically have sliding or flip-top covers that are locked using snap-fit ​​mechanisms, making opening and closing the compartments cumbersome and hindering the convenient handling of batteries. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a locking mechanism to solve the problem that the operation of charging batteries is not convenient enough in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is a locking mechanism for a charger. The locking mechanism has an unlocked state and a locked state, and includes: a first locking member, a second locking member, and a third locking member. The first locking member is used to connect to the first housing of the charger, and the third locking member is used to connect to the second housing of the charger. The second locking member and the third locking member are slidably connected. When the locking mechanism is in the unlocked state, the second locking member is locked in a first position by the third locking member and the first locking member is released. When the locking mechanism is in the locked state, the second locking member is locked in a second position by the third locking member and the first locking member is locked. The first locking member can move along a first direction to drive the second locking member to move between the first position and the second position, thereby switching the locking mechanism between the locked state and the unlocked state.

[0006] This utility model has at least the following beneficial effects: The first locking element drives the second locking element to move along a first direction. This movement of the second locking element in the first direction enables both unlocking and locking of the locking mechanism. Therefore, unlocking or locking can be completed with just one step: moving the first locking element along the first direction. No other directional or other forms of driving force are required; unlocking and locking are achieved solely through the unidirectional movement of the first locking element. In practical applications, simply pressing the first housing allows for locking and unlocking of both the first and second housings, making operation more convenient and providing a better user experience.

[0007] Furthermore, the second locking member is provided with a limiting groove, and the third locking member is provided with a limiting member, the limiting member being slidably disposed in the limiting groove; The second locking member is capable of moving relative to the third locking member in a first direction. When the second locking member moves to the first position, the limiting member slides to the first locking position of the limiting groove and abuts against the groove wall of the limiting groove. When the second locking member moves to the second position, the limiting member slides to the second locking position of the limiting groove and abuts against the groove wall of the limiting groove.

The end of the connecting section opposite to the rotating section is bent toward the second locking member to form a limiting post. The limiting post extends at least partially into the limiting groove.

[0010] Furthermore, an elastic element is provided between the second locking member and the third locking member.

[0011] Furthermore, the second locking member includes a body and at least two clamping arms rotatably connected to the body, the two clamping arms rotating relative to the body to move closer to or further away from each other, thereby clamping or releasing the first locking member.

[0012] Furthermore, the second locking member can move relative to the third locking member along a first direction, the first direction having a first positive direction and a first negative direction that are opposite to each other; The clamping arm is provided with a first driving part, and the third locking member is provided with a second driving part; when the second locking member moves relative to the third locking member in a first negative direction, the first driving part and the second driving part abut against each other and slide relative to each other, so that the two clamping arms rotate relative to the main body in a direction of mutual approach; when the second locking member moves relative to the third locking member in a first positive direction, the first driving part and the second driving part abut against each other and slide relative to each other, so that the two clamping arms rotate relative to the main body in a direction of mutual distance.

[0013] Furthermore, the end of the clamping arm opposite to the main body is provided with a hook; The first locking member includes a first surface facing away from the body and a second surface facing the body, and the two clamping arms are brought close together so that the hook abuts against the first surface and / or the second surface abuts against the body.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] Please refer to Figures 1 to 6The locking mechanism 500 and charger according to embodiments of this application are described in detail below. The charger includes a locking mechanism 500, a separable first housing 100, and a second housing 200. When the first housing 100 and the second housing 200 are joined together, they together define a receiving cavity, within which a charging component is installed. The charging component includes a circuit board, an energy storage battery module for storing electrical energy, and a mounting slot for mounting a battery to be charged. Before charging, the first housing 100 and the second housing 200 are separated to expose the mounting slot. Then, the battery to be charged from the electronic device is placed into the mounting slot, allowing the energy storage battery module to charge the battery. Finally, the first housing 100 is reinstalled into the second housing 200. For example, both the first housing 100 and the second housing 200 are configured as semi-enclosed structures, and the side plate of the first housing 100 is located inside the side plate of the second housing 200, so that the top plate of the first housing 100, the bottom plate of the second housing 200, and the side plates of the first housing 100 and the second housing 200 together form a receiving cavity for installing the charging component.

[0026] For the locking and unlocking structure of the first housing 100 and the second housing 200, please refer to... Figures 3 to 5 This embodiment discloses a locking mechanism 500 for a charger. The locking mechanism 500 has an unlocked state and a locked state, and includes: a first locking member 510, a second locking member 520, and a third locking member 530. The first locking member 510 is used to connect to the first housing 100 of the charger, and the third locking member 530 is used to connect to the second housing 200 of the charger. The second locking member 520 and the third locking member 530 are slidably connected. When the locking mechanism 500 is in the unlocked state, the second locking member 520 is locked in a first position by the third locking member 530 and the first locking member 510 is released. When the locking mechanism 500 is in the locked state, the second locking member 520 is locked in a second position by the third locking member 530 and the first locking member 510 is locked. The first locking member 510 can move along a first direction to drive the second locking member 520 to move between the first position and the second position, thereby switching the locking mechanism 500 between the locked state and the unlocked state.

[0027] The locking and unlocking steps of the locking mechanism 500 in this embodiment are roughly as follows: First, the positions of the second housing 200 and the third locking member 530 are fixed. Then, the first housing 100 is pressed along the first direction, thereby causing the first locking member 510 on the first housing 100 to abut against the second locking member 520 along the first direction, and causing the second locking member 520 to move relative to the third locking member 530 along the first direction. During the movement, the second locking member 520 can simultaneously lock or release the first locking member 510, and is locked in the first position or the second position by the third locking member 530.

[0028] As can be seen from the above, the first locking member 510 can drive the second locking member 520 to move along the first direction. The movement of the second locking member 520 along the first direction is sufficient to unlock and lock the locking mechanism 500. Therefore, unlocking or locking can be completed by simply moving the first locking member 510 along the first direction; no other directional or other form of driving force is required. Unlocking and locking can be achieved solely through the unidirectional movement of the first locking member 510. In practical applications, simply pressing the first housing 100 is sufficient to lock and unlock the first housing 100 and the second housing 200, making operation more convenient and providing a better user experience.

[0029] It should be noted that the locking mechanism 500 based on this embodiment provides a new unlocking and locking method, namely, a push-button type unlocking and locking. This differs from the conventional button-type structure, as it does not require applying force to a single location (i.e., the button). In this embodiment, the entire first housing 100 is pressed, and force can be applied to any position on the top plate of the first housing 100 during operation, making it suitable for blind operation and further improving the convenience of operation.

[0030] For the structure in which the second locking member 520 is locked by the third locking member 530 in the first and second positions, please refer to... Figure 5 The second locking member 520 is provided with a limiting groove 523, and the third locking member 530 is provided with a limiting member 550, which is slidably disposed in the limiting groove 523. The second locking member 520 can move relative to the third locking member 530 in a first direction. When the second locking member 520 moves to the first position, the limiting member 550 slides to the first locking position 5231 of the limiting groove 523 and abuts against the groove wall of the limiting groove 523. When the second locking member 520 moves to the second position, the limiting member 550 slides to the second locking position 5232 of the limiting groove 523 and abuts against the groove wall of the limiting groove 523.

[0031] Specifically, when the first housing 100 is pressed and the first locking member 510 is driven to abut against the second locking member 520 and move in the first direction, the limiting groove 523 of the second locking member 520 has relative movement with respect to the limiting member 550 of the third locking member 530 in the first direction, so that the limiting member 550 can slide in the fiber groove until the limiting member 550 slides to the first locking position 5231 or the second locking position 5232, the limiting groove 523 has a limiting effect on the limiting member 550, thereby locking the second locking member 520 in the first position or the second position.

[0032] Further, please refer to Figure 5The limiting groove 523 includes a first groove segment, a second groove segment, and two third groove segments. One of the third groove segments is connected to one end of the first groove segment and one end of the second groove segment, respectively. The other third groove segment is connected to the other end of the first groove segment and one end of the second groove segment, respectively. The first locking position 5231 is located in the first groove segment, and the first groove segment gradually tilts towards the first locking member 510 from the first position towards both ends. The second locking position 5232 is located in the second groove segment, and the second groove segment gradually tilts towards the first locking member 510 from the second position towards both ends.

[0033] For example, the limiting groove 523 has a closed annular structure, and sequentially includes a first groove segment, a third groove segment, a second groove segment, and another third groove segment along its circumferential direction. The first locking position 5231 is located in the middle of the first groove segment, and the first groove segment gradually slopes upwards from the first locking position 5231 towards both ends, so that the first locking position 5231 is located at the lowest point of the first groove segment, thereby locking the limiting member 550 at that position when it passes through the first locking position 5231. Similarly, the second locking position 5232 is located in the middle of the second groove segment, and the second groove segment gradually slopes upwards from the second locking position 5232 towards both ends, so that the second locking position 5232 is located at the lowest point of the second groove segment, thereby locking the limiting member 550 at that position when it passes through the second locking position 5232.

[0034] Specifically, when the second locking member 520 is in the first position, the limiting member 550 is in the first locking position 5231. If the first housing 100 is pressed down at this time, the first locking member 510 and the second locking member 520 will move downward, causing the limiting member 550 to slide along the first groove until it reaches the end of the first groove. If the first housing 100 is then moved upward, the limiting member 550 can slide along one of the third grooves until it slides into the second groove and is locked in the second locking position 5232. Similarly, when the second locking member 520 is in the second position, the limiting member 550 is in the second locking position 5232. If the first housing 100 is pressed down at this time, the limiting member 550 can slide along the second groove and into another third groove until it reaches the end of the third groove. If the first housing 100 is then moved upward, the limiting member 550 can slide from the end of the third groove into the first groove and be locked in the first locking position 5231.

[0035] Further, please refer to Figure 5The second locking member 520 has locking surfaces arranged opposite each other along a second direction, each locking surface being recessed inward to form a limiting groove 523; the limiting member 550 includes a rotating section 551 and two connecting sections 552 respectively connected to both ends of the rotating section 551. The rotating section 551 is rotatably disposed on the third locking member 530. The end of the connecting section 552 facing away from the rotating section 551 is bent toward the second locking member 520 to form a limiting post 553. The limiting post 553 extends at least partially into the limiting groove 523. Specifically, the rotating section 551 of the limiting member 550 is rotatably connected to the third locking member 530, so that when the limiting post 553 slides in the first or second groove, the limiting member 550 is allowed to rotate about the rotating section 551 as an axis, avoiding jamming and making its sliding smoother.

[0036] Further, please refer to Figure 3 An elastic element 540 is provided between the second locking member 520 and the third locking member 530. Specifically, the elastic element 540 is used to provide an upward preload to the second locking member 520, thereby compressing the elastic element 540 when the first housing 100 is pressed down, and releasing the elastic force when the first housing 100 is released, driving the second locking member 520 to move upward.

[0037] For the locking and unlocking structures of the second locking member 520 and the first locking member 510, please refer to... Figure 3 and Figure 4 The second locking member 520 includes a main body 522 and at least two clamping arms 521 rotatably connected to the main body 522. The two clamping arms 521 rotate relative to the main body 522 to move closer to or further away from each other, thereby clamping or releasing the first locking member 510. That is, the second locking member 520 clamps the first locking member 510 simultaneously by the two clamping arms 521 moving closer to each other, and releases the first locking member 510 simultaneously by the two clamping arms 521 moving further away from each other. In this way, the locking force of the second locking member 520 on the first locking member 510 can be enhanced. For example, the end of the clamping arm 521 connected to the main body 522 has a smaller thickness, making it more deformable and thus able to rotate relative to the main body 522 to clamp the first locking member 510, and able to rotate in the opposite direction to reset after deformation to release the first locking member 510. It is understood that the clamping arm 521 can be made of a material that is deformable but has a certain rigidity to provide sufficient clamping force, such as silicone.

[0038] Further, please refer to Figure 3The second locking member 520 is movable relative to the third locking member 530 along a first direction, which has a first positive direction and a first negative direction that are opposite to each other. The clamping arm 521 is provided with a first driving part 5212, and the third locking member 530 is provided with a second driving part 531. When the second locking member 520 moves relative to the third locking member 530 along the first negative direction, the first driving part 5212 and the second driving part 531 abut against each other and slide relative to each other, so that the two clamping arms 521 rotate relative to the main body 522 in a direction that brings them closer together. When the second locking member 520 moves relative to the third locking member 530 along the first positive direction, the first driving part 5212 and the second driving part 531 abut against each other and slide relative to each other, so that the two clamping arms 521 rotate relative to the main body 522 in a direction that moves them away from each other. For example, the first direction is a vertical direction, the first positive direction is a vertically upward direction, and the first negative direction is a vertically downward direction.

[0039] Specifically, the side plate of the third locking member 530 has a second driving part 531 at the end opposite to its base plate, and the clamping arm 521 has a first driving part 5212 on the side opposite to the first locking member 510. The maximum distance between the two first driving parts 5212 is greater than the minimum distance between the two second driving parts 531. Thus, when the second locking member 520 moves downward, the two clamping arms 521 gradually extend into the third locking member 530. The first driving part 5212 abuts against and slides relative to the second driving part 531. The second driving part 531 can abut against the first driving part 5212, causing the clamping arms 521 to move inward, thereby clamping the first locking member 510. Then, if the second locking member 520 moves upward at this time, the two clamping arms 521 gradually extend out of the third locking member 530 and return to their original position under their own elasticity, gradually rotating in the direction opposite to the first locking member 510, and finally releasing the first locking member 510.

[0040] Further, please refer to Figure 3 The clamping arm 521 has a hook 5211 at one end away from the main body 522; the first locking member 510 includes a first surface 511 on the side away from the main body 522 and a second surface 512 on the side facing the main body 522. The two clamping arms 521 are brought closer to each other so that the hook 5211 abuts against the first surface 511 and / or the second surface 512 abuts against the main body 522. For example, when the clamping arm 521 clamps the first locking member 510, the first locking member 510 is allowed to have a certain amount of room to move, that is, the first surface 511 abuts against the hook portion 5211, and at this time there is a gap between the second surface 512 and the main body 522, or there is a gap between the second surface 512 and the hook portion 5211, and the second surface 512 abuts against the main body 522; or, when the clamping arm 521 clamps the first locking member 510, the first locking member 510 is fastened and there is no room to move, that is, the first surface 511 abuts against the hook portion 5211, and the second surface 512 abuts against the main body 522.

[0041] For details regarding the charger's structure, please refer to... Figure 1 , Figure 2 and Figure 6 It includes: a locking mechanism 500, a first housing 100, and a second housing 200. The first housing 100 and the second housing 200 together define a receiving cavity for mounting a charging component, which supplies power to an external electronic device. A first locking member 510 is disposed in the first housing 100, a third locking member 530 is disposed in the second housing 200, and a second locking member 520 is slidably disposed in the third locking member 530. For example, the electronic device may specifically be a mobile phone, a portable music player, an iPad, or other audio / video playback device that requires charging.

[0042] Further, please refer to Figure 1 The charger also includes a solar panel 400 electrically connected to the charging components, which converts solar energy into electrical energy. Specifically, the charger in this embodiment also integrates a solar panel 400, which can convert solar energy into electrical energy and store the electrical energy in an energy storage battery module to charge the battery to be charged.

[0043] Further, please refer to Figure 6 The second housing 200 has a bottom surface for supporting the charger along a first direction; the second housing 200 is also provided with a slider 300, which has a first support portion 321 that can support the charger together with the bottom surface; the slider 300 can slide relative to the second housing 200 in a direction perpendicular to the first direction, so as to slide into or slide out of the second housing 200 at least partially.

[0044] Specifically, the slider 300 can slide laterally relative to the second housing 200, allowing it to partially or completely slide into the second housing 200 for easy storage, or partially or completely slide out of the second housing 200. The first support portion 321 of the slider 300 and the bottom surface of the second housing 200 jointly support the charger to enhance its stability and prevent it from tipping over.

[0045] Further, please refer to Figure 6 The second housing 200 has a side surface parallel to the first direction; the second housing 200 is also provided with a slider 300, and the slider 300 is provided with a second support portion 322; the slider 300 can slide relative to the second housing 200 in a direction perpendicular to the first direction, so as to at least partially slide into or at least partially slide out of the second housing 200; when the slider 300 slides out of the second housing 200 at least partially, the second support portion 322 and the side surface of the second housing 200 together form a structure for placing electronic equipment.

[0046] Specifically, when the slider 300 slides out of the second housing 200, one side of the electronic device can be directly placed on the second support 322 on the slider 300, while the other side of the electronic device rests against the side of the second housing 200, thereby providing a function for placing the electronic device.

[0047] For example, the slider 300 includes a horizontal plate 310 and a vertical plate 320. The horizontal plate 310 is slidably connected to the second housing 200. The vertical plate 320 is vertically fixed to the horizontal plate 310. The upper half of the vertical plate 320 and a portion of the vertical plate 320 constitute a second support portion 322, which, together with the side of the second housing 200, supports the electronic device. The lower half of the vertical plate 320 constitutes a first support portion 321, which, together with the bottom surface of the second housing 200, supports the charger.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
