Technical Field

[0001] This utility model relates to a quick-locking mechanism for a container lid, a container lid, and a container, belonging to the field of water containers for holding liquids. Background Technology

[0002] Most containers on the market that hold liquids have lids, which are usually opened and closed manually. This is slow and laborious, causing inconvenience for users.

[0003] Chinese patent CN2024105632872 discloses a relatively intelligent self-locking cup lid and water cup. It achieves locking through the cooperation of a rod and a socket. The rod is driven by a motor to raise and lower an eccentric wheel. The rod needs to be rotated to a reasonable position before it can be inserted into the socket. The locking process is complicated and the structure is cumbersome. It cannot achieve fast locking and unlocking, resulting in a poor user experience.

[0004] Therefore, it is necessary to improve the existing container lid and its locking mechanism. Utility Model Content

[0005] To address the aforementioned problems or one of the aforementioned problems, the purpose of this utility model is to provide a quick locking mechanism for a container lid, in which a driving source drives a rotating component to rotate, and a driving part on the rotating component drives a locking component to work. When the driving part rotates to the position of pressing against the locking component, it achieves quick locking; when it rotates to the position of disengaging from the locking component, it achieves release, thereby achieving the purpose of quick locking and unlocking.

[0006] In view of the above problems or one of the above problems, the second objective of this utility model is to provide a container lid that can achieve the purpose of quick locking and unlocking.

[0007] In view of the above problems or one of the above problems, the third objective of this utility model is to provide a container that can achieve the purpose of fast locking and unlocking.

[0008] To achieve one of the above objectives, the first technical solution of this utility model is as follows: A quick-locking mechanism for a container lid includes a drive source, a rotating component, and a locking component for securing the container lid to a container. The rotating component is provided with a driving part, which is used to drive the driving part to rotate. When the driving part is in contact with the locking component during rotation, it locks the component; when it is released from the locking component, it relaxes the component. The drive source is connected to the rotating component via a transmission connection.

[0009] As a preferred technical measure: The driving source is a motor or a combination of a motor and a transmission, wherein the motor is a DC motor, a micro stepper motor or a micro damping motor; Or / and, the locking component is a locking claw, an elastic hook, or a tensioning element; Or / and, the locking components and driving units are multiple in matching quantities; Or / and, the locking components are distributed around the periphery of the rotating member, the rotating member being an annular member, and the driving part being a protrusion with a guide surface located on the outer side of the annular member.

Alternatively, the gear assembly includes a drive gear and a micro gearbox, the drive gear being mounted on the output shaft of the drive source, the drive gear being connected to the input end of the micro gearbox, and the output end of the micro gearbox being connected to the gears on the annular member. Alternatively, the gear assembly includes a driving gear and a driven gear, the driving gear being disposed on the output shaft of the drive source, the driving gear and the driven gear meshing, and the driven gear meshing with the teeth on the annular member.

[0012] As a preferred technical measure: The annular component is the ring body of an annular cam and has an arc-shaped boss on the ring body. The arc-shaped boss has teeth, and the protrusion is the protruding part of the annular cam; or, the annular component is an internal toothed ring or a partially internal toothed ring, and the protrusion is an arc-shaped block located on the outer side of the internal toothed ring or the partially internal toothed ring.

[0013] To achieve one of the above objectives, the second technical solution of this utility model is as follows: A quick-locking mechanism for a container lid includes a motor, an annular cam, and several locking claws. The motor is drivenly connected to the annular cam, and the locking claws are distributed around the annular cam. The number of protrusions on the annular cam corresponds to the number of locking claws. When the protrusions of the annular cam abut against the locking claws, the cam locks; when they disengage from the locking claws, the cam releases. The rear end of the outer side of the protrusions of the annular cam is provided with a guide surface, which is an inclined surface, an arc surface, or a stepped guide surface.

[0014] To achieve one of the above objectives, the third technical solution of this utility model is as follows: A container lid includes a lid body and a quick-locking mechanism as described above.

[0018] Compared with existing technical solutions, this utility model has the following advantages: the rotating part is driven by the drive source to rotate, and the rotating part can rotate together with the drive part on it. When the drive part rotates to the position of pressing against the locking part, it locks; when it rotates to the position of disengaging from the locking part, it releases. Since the drive source only needs to rotate the rotating part through a very small angle to achieve the position switching of the drive part at the locking part, and all drive parts can work at the same time, the speed of locking and unlocking is very fast and convenient to use. In addition, this utility model has a simple structure and can be realized with very few parts, which can effectively control costs and improve product competitiveness. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Conversely, this utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, this utility model can be fully understood by those skilled in the art even without these detailed descriptions.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Example 1 like Figure 1 , 2 As shown, this embodiment provides a quick locking mechanism for a container lid, including a drive source 1, a rotating component 3, and a locking component 2 for fixing the container lid to the container; The rotating component 3 is provided with a driving part 4. The rotating component 3 is used to drive the driving part 4 to rotate. When the driving part 4 is in contact with the locking component 2 during rotation, it locks; when it is released from the locking component 2, it relaxes. The drive source 1 is connected to the rotating component 3 via a transmission connection.

[0025] The locking component 2 and the driving component 4 are multiple in number, such as four or five; Specifically, the locking component 2 is distributed around the rotating component 3, which is an annular component. The driving part 4 is a protrusion with a guide surface 64 located on the outer side of the annular component. To transition from the relaxed state to the locked state, the protrusion can more effectively and gradually enter the abutting area inside the locking component 2. The guide surface 64 is a slope, arc surface, or stepped guide surface at the rear end of the outer side of the protrusion. The stepped guide surface can be a multi-level slope or arc surface. The front-to-back relationship mentioned here refers to the running direction of the rotating component 3 when it is used for locking.

[0026] To achieve more precise transmission, the transmission connection between the drive source 1 and the rotating component 3 means that the annular component has transmission teeth; the drive source 1 engages with the teeth on the annular component through a gear assembly. Specifically, the annular component is the ring body 61 of an annular cam 6, and the ring body 61 is provided with an arc-shaped boss 63. The arc-shaped boss 63 is provided with teeth, and the protrusion is the protruding part 62 of the annular cam 6. The gear assembly includes an internal gear 71, a driving gear, an external gear 2 73, and an external gear 3 74. The driving gear is the external gear 1 72 and is disposed on the output shaft of the drive source 1. The external gear 1 72 also meshes with the internal gear 71. The internal gear 71 meshes with the external gear 2 73. The external gear 2 73 and the external gear 3 74 are connected by a shaft 75. The external gear 3 74 meshes with the teeth on the arc-shaped boss 63. The annular component can also be an internal gear ring. When a few teeth are sufficient to complete the transmission function, the annular component can also be a partial internal gear ring. The protrusion is an arc-shaped block located on the outer side of the internal gear ring or the partial internal gear ring. Obviously, there are many other ways to connect the drive source 1 with the rotating part 3. For example, the gear assembly includes a drive gear and a micro gearbox. The drive gear is mounted on the output shaft of the drive source 1. The drive gear is connected to the input end of the micro gearbox. The output end of the micro gearbox is connected to the gear on the ring-shaped part. The micro gearbox can better control the transmission ratio and can achieve faster locking and unlocking when the motor rotates through a smaller angle. Alternatively, the gear assembly includes a driving gear and a driven gear, with the driving gear mounted on the output shaft of the drive source 1, the driving gear and the driven gear meshing, and the driven gear meshing with the teeth on the annular member; those skilled in the art can also make other designs based on this.

[0027] In this embodiment, the driving source 1 is a motor, which can be selected from a DC motor, a micro stepper motor or a micro damping motor. In specific cases, a combination of a motor and a transmission can also be used. In this embodiment, the locking component 2 is a locking claw, which is hinged to the container lid, allowing the locking claw to rotate. When the inner side of the locking claw is pressed by a protrusion, it extends outward, thereby hooking onto the corresponding protruding ribs or other components on the container, thus achieving locking. A torsion spring is provided at the hinge of the locking claw to help the locking claw return to its original position as soon as it is relaxed. Of course, the locking claw can also return to its original position by gravity. In this case, the center of gravity of the locking claw can be designed to be further inward for faster return. The locking component 2 can also be an elastic hook, which is fixed to the container lid. Its hook body can deform and extend outward when compressed, thereby achieving locking. The locking component 2 can also be a hinged tensioning element or an elastic tensioning element.

[0028] The working principle of the quick-locking mechanism of the container lid described in this embodiment is as follows: When the locking component 2 is in the relaxed state, the container lid can be installed on the container. The motor rotates in the reverse direction, driving the external gear 1 72 to rotate. The external gear 1 72 drives the internal gear 71 to rotate. The internal gear 71 drives the external gear 2 73 to rotate. The external gear 2 73 and the external gear 3 74 rotate together. The external gear 3 74 drives the arc-shaped boss 63 to rotate, thereby causing the annular cam 6 to rotate. The protrusion 62 of the annular cam 6 slowly enters the area inside the locking component 2 and pushes outward toward the free end of the locking component 2, thereby achieving quick locking. When unlocking is required, the motor rotates in the forward direction, thereby driving the annular cam 6 to rotate in the opposite direction to the direction of locking. The protrusion 62 of the annular cam 6 slowly rotates out of the area inside the locking component 2 and finally disengages from the locking component 2. The locking component 2 loses its support and relaxes, thereby forming quick unlocking.

[0029] Furthermore, for better positioning, this embodiment may also include a stop block 5. When the locking component 2 is released, the stop block 5 abuts against the front of the drive unit 4, which can prevent the annular cam 6 from rotating excessively. At this time, since the drive unit 4 is limited by the stop block 5, if the drive gear is a full gear, the motor needs to be precisely controlled. Therefore, the drive gear may be missing one or more teeth, so that clutch engagement can be achieved. When the drive unit 4 is blocked by the stop block 5, the drive gear rotates to the toothless part, so that the power is disengaged from the transmission component, thereby protecting the drive source.

[0030] Furthermore, in order to enable manual operation, a lever 76 is provided on the upper end face of the internal gear 71, and a person's hand can operate the annular cam with the lever to lock and unlock it.

[0031] Example 2 like Figure 3-6 As shown, this embodiment provides a container lid, including a lid body 8, and also includes the quick locking mechanism of the container lid described in Embodiment 1 above; the lid body 8 is provided with a device cavity 81, the drive source 1 is fixedly disposed in the device cavity 81, and the rotating component 3 is rotatably disposed in the device cavity 81; the locking component 2 is movably disposed on the lid body 8.

[0032] Furthermore, the device cavity 81 is provided with four stops 5, the rotating member 3 is located inside the stops 5 and can rotate, and when the locking member 2 is released, the stops 5 abut against the front of the driving part 4; There are four locking components 2 and four driving components 4.

[0033] Furthermore, such as Figure 7As shown, the container lid described in this embodiment may also be provided with an exposed lever cavity 77. The bottom surface of the lever cavity 77 is provided with an arc-shaped through groove 78. The lever 76 on the quick-locking mechanism of the container lid can extend into the lever cavity and move within the arc-shaped through groove 78. The exposed lever cavity 77 means that a flip cover or a detachable touch screen can be provided above the lever cavity 77.

[0034] Example 3 like Figure 8 As shown, this embodiment provides a container, including a container body 9 and a container lid as described in Embodiment 2 above. The container body 9 is provided with a rib 91 that cooperates with the locking component 2.

[0035] The container can be a teapot, a thermos, or a kettle.

[0036] Example 4 This embodiment provides a quick-locking mechanism for a container lid, including a motor, an annular cam 6, and several locking claws. The motor is connected to the annular cam 6 for transmission. The locking claws are distributed around the annular cam 6. The number of protrusions 62 on the annular cam 6 corresponds to the number of locking claws. When the protrusions 62 of the annular cam 6 press against the locking claws, the lid is locked; when the protrusions 62 of the annular cam 6 disengage from the locking claws, the lid is released. The rear end of the outer side of the protrusions 62 of the annular cam 6 is provided with a guide surface 64, which is an inclined surface, an arc surface, or a stepped guide surface.

[0037] Example 5 This embodiment provides a container lid, including a lid body 8 and a quick-locking mechanism for the container lid as described in Embodiment 4; the lid body 8 has a device cavity 81, the motor is fixedly installed in the device cavity 81, the device cavity 81 has a plurality of stops 5, the annular cam 6 is located inside the stops 5 and is rotatable, when the locking pawl is released, the stops 5 abut against the front of the protrusion 62 of the annular cam 6; the locking pawl is hinged to the lid body 8.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify or make equivalent substitutions to the specific implementation of this utility model.
