Description

Technical Field

[0001] This utility model relates to the technical field of trash can structure, and in particular to a damping component, a lid, and a trash can. Background Technology

[0002] In the prior art, some trash cans include a can body and a can lid. The can lid includes a rotatable lid body, a torsion spring that drives the lid body to rotate and open, and a control button. The control button is engaged with the lid body so that the lid body closes the can body. When the engagement is released, the torsion spring drives the lid body to rotate, so that the lid body rotates and opens, allowing trash to be thrown into the can.

[0003] When the torsion spring drives the lid to rotate, the rotational speed of the lid continuously increases. At the same time, the lid or barrel is equipped with a limiting structure, such as a limiting pin or a limiting post. Therefore, during the rotation, the lid will suddenly stop because it touches the limiting structure.

[0004] However, due to inertia, other parts of the lid will continue to rotate, making the base of the lid prone to cracking, such as at the contact limit structure. Also, in some lighter trash cans, inertia can cause the lid to move along the can, causing the trash can to tip over. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a damping component that can increase rotational resistance, causing the cover to decelerate before reaching its final rotation point, thereby reducing the risk of cracking and tipping.

[0010] A second abutting portion is disposed on the second component, wherein the first abutting portion and the second abutting portion abut against each other to provide rotational resistance, the rotational resistance being used to impede the rotation of the first component;

[0011] When the first component rotates relative to the second component to open, the contact strength between the first abutment and the second abutment increases, thereby increasing the rotational resistance.

[0012] The damping component according to the embodiments of the present invention has at least the following beneficial effects:

[0013] By providing a first abutting part and a second abutting part, when the first component rotates relative to the second component, the first abutting part will come into contact with the second abutting part, generating frictional force, thereby hindering the rotation of the first component and satisfying the need to decelerate the first component.

[0014] When the first component rotates relative to the second component to open, this invention increases the frictional force by increasing the contact strength between the first and second abutting parts, thereby increasing the rotational resistance to overcome the torsion spring effect and slow down the rotation of the first component. As a result, when the first component rotates to the end point, the speed of the first component is small, such as close to zero, which can reduce the inertial effect and reduce the risk of cracking and tipping caused by inertia.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The damping component, bucket lid, and trash can according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0043] Reference Figure 1 The present invention aims to provide an embodiment of a trash can.

[0044] In this embodiment, the trash can includes a body 110 and a lid 100. The body 110 can be single-layered or multi-layered. The multi-layered body 110 includes an upper body 110 and a lower body 110 that are adjacent to each other. The upper body 110 and the lower body 110 are fitted together, which can increase the volume of the trash can and increase its capacity to store trash.

[0045] In some specific embodiments of this utility model, one of the upper bucket 110 and the lower bucket 110 can be stored in the other to reduce space occupation and facilitate transportation.

[0046] In this embodiment, the lid 100 includes a lid body 120 and a frame body 130. The frame body 130 is installed on the upper edge of the lid body 110, and the inner side of the frame body 130 forms a channel for garbage to fall, making it convenient to put garbage into the garbage bin.

[0047] The lid 120 is rotatably connected to the frame 130. When the lid 120 is rotated open, it can be used to dispose of garbage. When the lid 120 is rotated closed, it can cover the inside of the frame 130, thereby sealing the garbage can and reducing insects and odors.

[0048] Reference Figure 2 and Figure 3For the rotatable connection between the cover 120 and the frame 130, the cover 120 and the frame 130 can be provided with a connecting mechanism. The connecting mechanism includes a first component 150 connecting the cover 120 and a second component 160 connecting the frame 130. The first component 150 and the second component 160 are rotatably connected, thereby simplifying the structure of the cover 120 and the frame 130 and facilitating manufacturing.

[0049] Reference Figure 1 In this embodiment, the frame 130 is provided with a button that can be engaged with the edge of the cover 120 to keep the cover 120 closed. Pressing the button rotates it away from the cover 120, releasing the engagement and allowing the cover 120 to rotate freely to open.

[0050] The frame 130 is equipped with a reset spring, which causes the button to rotate toward the cover 120, so that the button and the cover 120 are locked together. The frame 130 is also equipped with a drive spring, which drives the cover 120 to rotate, so that the cover 120 can automatically rotate and open.

[0051] To drive the lid 120 to rotate, the initial force of the torsion spring is set to be relatively large, thereby accelerating the rotation of the lid 120 and achieving the purpose of opening quickly. At the same time, when the lid 120 rotates to the end point, the final force of the torsion spring will still be relatively large, so that the lid 120 stays at the end point of rotation and reduces shaking.

[0052] Structurally, at the end point of rotation of the lid 120, the lid 100 or the barrel 110 will be equipped with a limiting structure, such as a limiting pin, a limiting post, or a limiting block. The lid 120 will suddenly stop when it touches the limiting structure.

[0053] Due to inertia, other parts of the cover 120 will continue to rotate, causing the cover 120 to deform and making the root of the cover 120 prone to cracking, such as the position of the contact limiting structure on the cover 120.

[0054] Meanwhile, in some lighter trash cans 110, inertia will cause the lid 120 to move the can 110, causing the trash can to tip over.

[0055] Meanwhile, in some trash cans with a relatively high and light body 110, the inertia will cause the lid 120 to move the body 110 due to the high center of gravity of the trash can, making the trash can easier to tip over.

[0056] Reference Figures 2 to 6 To address the above issues, the connecting mechanism in this embodiment is further provided with a damping component 140. The damping component 140 can increase the rotational resistance, causing the cover 120 to decelerate before reaching the end point, thereby reducing the risk of cracking and tipping.

[0057] Specifically, the damping assembly 140 includes a first abutment portion 170 and a second abutment portion 180. The first abutment portion 170 is disposed on the first component 150, and the second abutment portion 180 is disposed on the second component 160. The first abutment portion 170 and the second abutment portion 180 abut against each other to provide rotational resistance, which is used to impede the rotation of the first component 150.

[0058] When the first component 150 rotates relative to the second component 160 to open, the contact strength between the first abutment portion 170 and the second abutment portion 180 increases, thereby increasing the rotational resistance.

[0059] In summary, by providing a first abutting part 170 and abutting part 180, this utility model ensures that when the first component 150 rotates relative to the second component 160, the first abutting part 170 will come into contact with the second abutting part 180, generating frictional force, thereby hindering the rotation of the first component 150 and satisfying the need to decelerate the first component 150.

[0060] When the first component 150 rotates relative to the second component 160 to open, the present invention increases the frictional force by increasing the contact strength between the first contact portion 170 and the second contact portion 180, thereby increasing the rotational resistance to overcome the torsion spring effect and slowing down the rotation of the first component 150. As a result, when the first component 150 rotates to the end point, the speed of the first component 150 is small, close to zero, which can reduce the inertial effect and reduce the risk of cracking and tipping caused by inertia.

[0061] In some specific embodiments of this utility model, the first abutting part 170 can be integrally disposed on the first component 150, or the second abutting part 180 can be integrally disposed on the second component 160, so as to reduce the number of parts and reduce manufacturing costs.

[0062] In some specific embodiments of this utility model, the first abutment portion 170 can be provided as a separate part without affecting the manufacturing of the first component 150, while increasing the strength of the first component 150.

[0063] In this embodiment, the first abutting part 170 is integrally disposed on the first component 150, while the part to which the second abutting part 180 belongs is an independent component of the second component 160, thereby taking into account both manufacturing and performance.

[0064] In some specific embodiments of this utility model, the first component 150 may have a first axial direction, the first axis being the rotation center of the first component 150, and the first abutting part 170 and the second abutting part 180 abutting along the first axial direction.

[0065] The first abutting part 170 and the second abutting part 180 abut together along the first axis direction, which can utilize the internal space of the frame 130, while avoiding increasing the volume of the frame 130 and not affecting the size of the trash can opening, thus making full use of the space.

[0066] In some specific embodiments of this utility model, the first component 150 can have a first circumferential direction, which is the rotational movement about a first axis, that is, the tangential direction of the rotation of the first component 150. The first abutting part 170 and the second abutting part 180 abut along the first circumferential direction. Similarly, the rotational resistance can be changed by making the radial dimensions of the first abutting part 170 and the second abutting part 180 to the first axis different, so as to meet different usage needs, such as adapting to the case where the sides where the first component 150 and the second component 160 are located are relatively short.

[0067] Reference Figures 2 to 6 This embodiment is illustrated and illustrated by showing the first abutting part 170 and the second abutting part 180 abutting along the first axis direction.

[0068] In some specific embodiments of this utility model, the first abutting part 170 may include an arc-shaped abutting area 190, which is used to abut the second abutting part 180. The arc-shaped abutting area 190 has a second axial direction, which is parallel to the first axial direction. The arc-shaped abutting area 190 is offset along the first axial direction.

[0069] In this embodiment, the first axis and the second axis coincide, so that the contact positions of the first contact portion 170 and the second contact portion 180 are arranged with the first axis as the center, such as the arc-shaped contact area 190. The structure is compact and occupies little space. Moreover, the contact position is easy to identify, which meets the needs of use.

[0070] Since the arc-shaped contact area 190 is an arc centered on the first axis, the contact positions of the first contact portion 170 and the second contact portion 180 are deviated from the first axis. The contact between the first contact portion 170 and the second contact portion 180 can not only generate rotational resistance, but also generate torque that hinders rotation, thereby increasing the strength and efficiency of hindering rotation.

[0071] The arc-shaped abutment area 190 is offset along the first axis direction, which means that there is a height difference in the arc-shaped abutment area 190 along the first axis direction. Therefore, when the first component 150 rotates, one position of the arc-shaped abutment area 190 is closer to the second abutment part 180 than the other position, which can improve the abutment strength between the first abutment part 170 and the second abutment part 180, thereby increasing the rotational resistance and increasing the damping, so that the first component 150 and the cover 120 decelerate.

[0072] In some specific embodiments of this utility model, the first abutting part 170 may include an arc-shaped arm 200, and an arc-shaped abutting area 190 may be provided on one side of the arc-shaped arm 200 in the axial direction direction.

[0073] It is easy to understand that by setting the arc arm 200, this embodiment can overcome the shape limitations of the first component 150, increase the area of ​​the first contact portion 170, facilitate the formation of the arc contact area 190, and meet the need for continuous contact to decelerate.

[0074] In some specific embodiments of this utility model, the end of the arc arm 200 may be provided with an axially protruding limiting part 210, which cooperates with the second abutting part 180 to limit the angle of rotation of the first component 150 relative to the second component 160.

[0075] It is easy to understand that the axial protruding limiting part 210 cooperates with the second abutting part 180 to prevent the second abutting part 180 from going over the first abutting part 170 and to avoid the second abutting part 180 abutting the end of the arc-shaped arm 200 and affecting the reverse rotation of the cover 120.

[0076] Meanwhile, the axially protruding limiting part 210 cooperates with the second abutting part 180. Specifically, the axially protruding limiting part 210 and the second abutting part 180 abut circumferentially along the rotation direction of the first component 150, which can limit the rotation angle of the first component 150 without the need for a separate limiting structure, thus simplifying the structure.

[0077] In some specific embodiments of this utility model, the second component 160 may be provided with a first groove 220, which is used to accommodate the rotation of the arc-shaped arm 200.

[0078] It is easy to understand that by setting the first groove 220, this embodiment can avoid the arc arm 200, so as to adapt to the situation where the position of the arc arm 200 changes continuously when the first component 150 rotates.

[0079] In some specific embodiments of this utility model, the side of the arc arm 200 facing away from the arc abutment area 190 can be a plane perpendicular to the first axis, reducing the space occupied and eliminating the need to increase the size of the first groove 220.

[0080] Reference Figures 4 to 6 In some specific embodiments of this utility model, the second abutting part 180 may include a ball 230, which is used to abut the first abutting part 170. Therefore, it can not only meet the abutting requirements, but also reduce wear and extend the service life of the damping component 140.

[0081] In some specific embodiments of this utility model, the second abutment portion 180 may include an axial sliding member 240 and an elastic member 250. The axial sliding member 240 is provided with a ball 230, and the elastic member 250 drives the axial sliding member 240 to slide so that the ball 230 abuts against the first abutment portion 170.

[0082] It is easy to understand that in this embodiment, by setting an axial sliding member 240 and an elastic member 250, the axial sliding member 240 will continuously approach the first abutment portion 170 under the action of the elastic member 250, so that the ball 230 continuously contacts the first abutment portion 170, that is, continuously contacts the arc-shaped abutment area 190, and continuously generates rotational resistance.

[0083] In some specific embodiments of this utility model, the axial sliding member 240 can include an outer sleeve 241 and an inner core 242. The outer sleeve 241 and the inner core 242 cooperate to position the ball bearing 230, which reduces the difficulty of installing the ball bearing 230, prevents the ball bearing 230 from falling off, and also facilitates the replacement of worn ball bearing 230.

[0084] Specifically, the outer casing 241 has an opening smaller than the diameter of the ball 230, so that the ball 230 protrudes outward to contact the first abutment portion 170, but the ball 230 will not come out of the opening.

[0085] The inner core 242 will contact the ball 240 in the direction away from the first abutment 170. At the same time, the inner core 242 will cooperate with the outer shell 241 to form the installation space for the ball 230, so as to prevent the ball 230 from moving freely.

[0086] The inner core 242 will have the same columnar structure as the positioning post 310 to position the other end of the elastic element 250, so as to facilitate the transmission of the elastic force of the elastic element 250 to the ball 230 and meet the need to generate rotational resistance.

[0087] Reference Figure 4 and Figure 6 In some specific embodiments of this utility model, the second component 160 may be provided with a second groove 260 for mounting and accommodating the sliding of the axial sliding member 240. The second groove 260 is provided with a first radial opening 270, which is arranged along the opening and closing direction of the second component 160.

[0088] It is easy to understand that, in this embodiment, the movement trajectory of the axial sliding member 240 can be restricted by the second groove 260, so as to ensure that the force of the elastic member 250 drives the axial sliding member 240 to approach the first abutment part 170.

[0089] The first radial opening 270 is provided to facilitate injection molding, so as to meet the installation requirements of the axial sliding member 240 and the elastic member 250.

[0090] In some specific embodiments of this utility model, the injection mold of the second component 160 can be provided with a side core pull to form a hole on the side wall of the second groove 260, which facilitates the formation of a slide for the axial sliding member 240 to slide, and avoids the draft angle from affecting the sliding trajectory of the axial sliding member 240.

[0091] In some specific embodiments of this utility model, the second groove 260 may be provided with a second radial opening 280 opposite to the first radial opening 270. The side of the second radial opening 280 away from the first radial opening 270 is connected to a central hole 290. The central hole 290 is used to provide a shaft, and the shaft is used to rotatably connect the first component 150 and the second component 160.

[0092] It is easy to understand that by setting a second radial opening 280 opposite to the first radial opening 270, the center hole 290 can be directly formed in the mold opening and closing direction during injection molding, reducing the use of side core pulling, simplifying the mold structure, and improving the mold service life.

[0093] In some specific embodiments of this utility model, the second groove 260 may be provided with a third radial opening 300 opposite to the first radial opening 270. The side of the third radial opening 300 away from the first radial opening 270 is open. The elastic element 250 includes a spring. The side wall of the second groove 260 is provided with a positioning post 310. The positioning post 310 is located between the first radial opening 270 and the third radial opening 300. The spring is fitted onto the positioning post 310.

[0094] It is easy to understand that, by setting a third radial opening 300, the positioning post 310 can be formed by the mold mating. That is, both parts of the mold are provided with recesses, and the two recesses are opposite to each other and cooperate to form a local forming cavity for forming the positioning post 310, which can reduce the forming difficulty of the positioning post 310 during injection molding production.

[0095] The positioning pin 310 is located in the second groove 260. The space inside the second groove 260 is small, and there is insufficient space to set up the inclined core pulling structure. Moreover, it makes the mold structure complicated.

[0096] In this embodiment, in order to achieve balanced force distribution, a damping component 140 is provided on both sides of the first axis direction of the first component 150, which can reduce the intensity of the action of a single damping component 140.

[0097] In some specific embodiments of this utility model, the second component 160 can be hollow and has a side opening. The side opening is used to limit the torsion spring that drives the first component 150 to rotate. This can reduce weight and injection molding shrinkage, and eliminate the need for a separate structure for the torsion spring.

[0098] In some specific embodiments of this utility model, the first component 150 can have two mounting tubes, and the mounting tubes are provided with a pivot for connecting the center hole 290 of the second component 160, which facilitates installation and at the same time shortens the core-pulling length and reduces the difficulty of injection molding.

[0099] This embodiment provides a button-operated multi-layer trash can, but the damping component of this embodiment can also be applied to other trash can types such as button-operated single-layer trash cans, pedal-operated multi-layer trash cans, and pedal-operated single-layer trash cans.

[0100] As is easily understood, the damping component of this embodiment can also be applied to situations such as rice cookers, doors and windows that require deceleration during rotation.
