Abstract
Description
Technical Field
[0001] This utility model relates to the field of door handle technology, and in particular to a self-springing device, a handle, and a door. Background Technology
[0002] As an important door accessory, door handles have both decorative and functional functions. Typically, a door handle consists of a handle body, a back cover, and a handle cover. In the current technology, when a door handle needs to be repaired, it is usually necessary to use tools to pry open the handle cover or to use fingernails to remove it.
[0003] For example, in smart door locks, the battery is usually located inside the back cover. Specifically, the handle body and handle cover are connected to the back cover in sequence, thus sealing the battery inside the back cover. However, when the battery fails, it is necessary to use a flathead screwdriver, pry bar, or key to gently pry open the handle cover by inserting it into the gap between the handle cover and the back cover. This can easily damage the handle, is inefficient, and inconvenient to operate. Utility Model Content
[0004] The purpose of this invention is to solve the problem of handles being difficult to install and remove in the prior art. This invention provides a self-opening device, handle, and door that allows for efficient and convenient installation and removal of handle covers without the need for tools or fingernails to pry them open.
[0005] To address the aforementioned technical problems, this utility model discloses a self-ejecting device capable of switching between a locked and unlocked state. The self-ejecting device includes:
[0006] A pressing part is provided for insertion into the rear cover of the handle;
[0007] An elastic element, along a first direction, has one end disposed on the pressing portion and the other end disposed on the rear cover;
[0008] A first connecting part, along the second direction, has one end connected to the pressing part and the other end detachably connected to the handle cover;
[0009] In the locked state, the elastic element is in a first compressed state, and along the first direction, the pressing part protrudes from the rear cover, and one end of the first connecting part is connected to the handle cover; in the unlocked state, the elastic element is in a second compressed state, and along the first direction, the pressing part does not protrude from the rear cover, and one end of the first connecting part is detached from the handle cover.
[0010] By employing the above technical solution, a smooth transition between locked and unlocked states can be achieved through the synergistic action of the pressing part, the elastic element, and the first connecting part. Specifically, the elastic element provides power during the compression state change, and the first connecting part ensures the detachable connection of the handle cover. In the locked state, the elastic element is in the first compressed state, generating a downward reaction force that causes the pressing part to protrude from the back cover, thus maintaining the connection between one end of the first connecting part and the handle cover. To unlock, simply press the aforementioned pressing part upwards, switching the elastic element to the second compressed state. This detaches one end of the first connecting part from the handle cover, causing the handle cover to automatically pop open. This state-switching mechanism creates a "one-click self-opening" effect, significantly improving operational convenience and safety. The handle cover can be installed and removed efficiently and conveniently without the need for tools or fingernails to pry it open.
[0011] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a self-elastic device, including a guide groove, the guide groove being formed in the pressing part, the first connecting part extending from the outer wall of the guide groove along a second direction, one end of the elastic member being disposed in the guide groove, and at least a portion of the elastic member being disposed within the guide groove.
[0012] By adopting the above technical solution, the first connecting part can extend along the outer wall of the guide groove and partially accommodate the elastic element through the cooperation of the guide groove, the pressing part, the elastic element and the first connecting part. The guide groove guides the first connecting part and the elastic element to move in a predetermined direction, optimizes the movement trajectory, avoids deviation or jamming during the pressing process, and thus improves the accuracy and reliability of the self-spring.
[0013] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a self-elastic device, including a guide post, which protrudes from the pressing part along the first direction, and the elastic element is sleeved on the guide post.
[0014] By adopting the above technical solution, the elastic element can be sleeved on the guide post through the cooperation of the guide post, the pressing part and the elastic element, so that the elastic element maintains linear motion during compression and reset, reducing bending and friction. Working together with the pressing part, it improves the response speed and consistency of the self-elastic device.
[0015] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a self-elastic device, including a first elastic snap-fit part, which protrudes from the other end of the first connecting part and is used to snap-fit with the handle cover.
[0016] By adopting the above technical solution, the first elastic locking part can quickly engage and disengage with the handle cover through the cooperation of the first elastic locking part, the first connecting part, and the pressing part. When the pressing part is pressed and moves upward, the first elastic locking part moves upward accordingly and automatically deforms to release the handle cover, making the unlocking process gentler and more reliable, avoiding hard collisions and improving user-friendliness.
[0017] This utility model also discloses a handle, comprising:
[0018] The self-ejecting device in any of the above embodiments;
[0019] The self-elastic device is located on the rear cover;
[0020] A handle cover, one end of which is connected to the first connecting part of the self-springing device;
[0021] The main body is located between the rear cover and the handle cover, with the other end of the handle cover connected to the main body.
[0022] By adopting the above technical solution, a complete handle unit can be formed through the coordinated assembly of the self-springing device with the back cover, handle cover and body. The function of the self-springing device is combined with the handle structure, which improves the ease of opening the handle cover and the overall stability.
[0023] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a handle, wherein one end of the handle cover is provided with a second elastic snap-fit portion, and the first elastic snap-fit portion and the second elastic snap-fit portion are connected.
[0024] By adopting the above technical solution, a double-clamping interface can be formed through the cooperative connection of the second elastic clamping part and the first elastic clamping part. The two elastic clamping parts cooperate with each other to enhance the connection strength of the handle cover, prevent accidental loosening, and work together with the self-springing device to improve the durability and safety of the overall structure.
[0025] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a handle, wherein the handle cover is made of an elastic material, and a third elastic snap-fit portion is provided at the other end of the handle cover. The body includes a snap-fit platform, and the third elastic snap-fit portion can snap into the snap-fit platform.
[0026] By adopting the above technical solution, multi-point fixation can be achieved through the cooperation of the elastic material of the handle cover, the third elastic locking part, and the main body locking platform. The elastic material allows the handle cover to deform slightly during locking, and the third elastic locking part can lock onto the locking platform. Therefore, when the handle cover is connected to the handle body, the self-springing device is in a locked state, and the handle cover is in a slightly deformed state. When the self-springing device switches to the unlocked state, the handle cover can automatically pop out of the handle body.
[0027] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a handle, wherein the bottom of the back cover is provided with a mounting groove, the pressing part of the self-spring device is used to pass through the mounting groove, in the locked state, the pressing part passes through the mounting groove along the first direction, and in the unlocked state, the pressing part is disposed in the mounting groove.
[0028] By adopting the above technical solution, the pressing part moves more smoothly when switching states through the mounting groove, and works in conjunction with the back cover to reduce external interference and improve the cleanliness and protection of the device.
[0029] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a handle, including a cover plate, the cover plate being disposed at the opening of the mounting groove, the cover plate and the mounting groove together forming a cavity, and the cover plate being detachably connected to the rear cover.

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0050] In some embodiments, see Figure 1 , Figure 2 This application provides a door, including a handle 10, a door lock (not shown in the figure), and a door frame (not shown in the figure). The handle 10 includes a self-opening device 11, a rear cover 12, a handle cover 13, and a body 14. Along a first direction X, the handle cover 13 and the rear cover 12 are disposed on both sides of the body 14, with the handle cover 13 fitted snugly against the body 14. The handle cover 13 and the body 14 are arranged in an arc shape. Along a second direction Y, one end of the body 14 and the rear cover 12 are spaced apart to form a "V"-shaped gap 15, facilitating the user to insert their finger into the gap 15 to open the door. It is understood that the shape of the gap 15 is not limited in this embodiment; for example, it can be "U"-shaped.
[0051] For example, the self-springing device 11 is disposed on the side of the rear cover 12 away from the gap 15 along the second direction Y, one end of the handle cover 13 is detachably connected to the self-springing device 11, the body 14 is disposed between the rear cover 12 and the handle cover 13, and the other end of the handle cover 13 is connected to the body 14.
[0052] In some embodiments, the self-elastic device 11 can switch between a locked state and an unlocked state. The self-elastic device 11 includes a pressing part 111, an elastic member 112, and a first connecting part 113. Exemplarily, the pressing part 111 is inserted into the rear cover 12 of the handle 10. Along a first direction X, one end of the elastic member 112 is disposed on the pressing part 111, and the other end is disposed on the rear cover 12. Along a second direction Y, one end of the first connecting part 113 is connected to the pressing part 111, and the other end is detachably connected to the handle cover 13.
[0053] In the locked state, the elastic element 112 is in a first compressed state, and the pressing part 111 protrudes from the back cover 12 along the first direction X, and one end of the first connecting part 113 is connected to the handle cover 13; in the unlocked state, the elastic element 112 is in a second compressed state, and the pressing part 111 does not protrude from the back cover 12 along the first direction X, and one end of the first connecting part 113 is detached from the handle cover 13.
[0054] By employing the above technical solution, a smooth transition between locked and unlocked states can be achieved through the coordinated action of the pressing part 111, the elastic element 112, and the first connecting part 113. Specifically, the elastic element 112 provides power during the compression state change, and the first connecting part 113 ensures the detachable connection of the handle cover 13. In the locked state, the elastic element 112 is in the first compression state, at which point it generates a downward reaction force that causes the pressing part 111 to protrude through the back cover 12, thus maintaining the connection between one end of the first connecting part 113 and the handle cover 13. When unlocking is required, simply press the aforementioned pressing part 111 upwards to switch the elastic element 112 to the second compression state. One end of the first connecting part 113 disengages from the handle cover 13, causing the handle cover 13 to automatically pop open. This state-switching mechanism creates a "one-click self-opening" effect, significantly improving the convenience and safety of operation. The handle cover 13 can be installed and removed efficiently and conveniently without the need for tools or fingernails to pry it open.
[0055] In some embodiments, see Figure 1 , Figure 2 , Figure 3 Along the first direction X, the bottom of the rear cover 12 is provided with a mounting groove 121. The pressing part 111 of the self-springing device 11 is used to pass through the mounting groove 121. In the locked state, the pressing part 111 extends out of the mounting groove 121 along the first direction X. In the unlocked state, the pressing part 111 is disposed in the mounting groove 121. Exemplarily, the first connecting part 113 extends along the second direction Y, and one end of the pressing part 111 and the first connecting part 113 are integrally formed.
[0056] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The self-elastic device 11 includes a first elastic locking portion 114, which protrudes downward along the first direction X at the other end of the first connecting portion 113 for engaging with the handle cover 13. Exemplarily, along the first direction X, one end of the handle cover 13 protrudes upward with a second elastic locking portion 131, and the first elastic locking portion 114 and the second elastic locking portion 131 are connected.
[0057] In some embodiments, see Figure 1 , Figure 2 , Figure 4The handle cover 13 is made of an elastic material, and a third elastic snap-fit portion 132 protrudes from the other end of the handle cover 13. The body 14 includes a snap-fit platform 141, and the third elastic snap-fit portion 132 can snap onto the snap-fit platform 141. Exemplarily, the elastic material can be polyethylene, etc., and this application embodiment does not limit it. Multi-point fixation is achieved through the cooperation of the elastic material of the handle cover 13, the third elastic snap-fit portion 132, and the snap-fit platform 141 of the body 14. The elastic material allows the handle cover 13 to deform slightly when snapped, and the third elastic snap-fit portion 132 can snap onto the snap-fit platform 141. Therefore, when the handle cover 13 is connected to the body 14 of the handle 10, the self-spring device 11 is in a locked state, and the handle cover 13 is in a slightly deformed state. When the self-spring device 11 switches to the unlocked state, the handle cover 13 can automatically pop out of the body 14 of the handle 10.
[0058] In some embodiments, see Figure 5 , Figure 6 , Figure 7 and combined Figure 3 The self-elastic device 11 includes a guide groove 115 located within the mounting groove 121. The guide groove 115 is formed in the pressing part 111. A first connecting part 113 extends from the outer wall of the guide groove 115 along the second direction Y. One end of the elastic member 112 is located in the guide groove 115, and at least a portion of the elastic member 112 is located within the guide groove 115. The other end of the elastic member 112 is located on the top wall 1211 of the mounting groove 121. Through the cooperation of the guide groove 115 with the pressing part 111, the elastic member 112, and the first connecting part 113, the first connecting part 113 extends along the outer wall 1151 of the guide groove 115 and partially accommodates the elastic member 112. The guide groove 115 guides the first connecting part 113 and the elastic member 112 to move in a predetermined direction, optimizing the movement trajectory and avoiding deviation or jamming during the pressing process, thereby improving the accuracy and reliability of the self-elasticity.
[0059] In some embodiments, the self-elastic device 11 includes a guide post (not shown) protruding from the pressing part 111 within the mounting groove 121 along the first direction X, and an elastic member 112 sleeved on the guide post. Through the cooperation of the guide post with the pressing part 111 and the elastic member 112, the elastic member 112 is sleeved on the guide post, ensuring that the elastic member 112 maintains linear motion during compression and reset, reducing bending and friction. Working in conjunction with the pressing part 111, it improves the response speed and consistency of the self-elastic device 11. It is understood that the self-elastic device 11 may also include both a guide groove 115 and a guide post; this embodiment does not limit this.
[0060] In some embodiments, see Figure 8 , Figure 9 , Figure 10 and combined Figure 5The handle 10 includes a cover plate 16, which is disposed at the opening of the mounting groove 121. The cover plate 16 and the mounting groove 121 together form a dustproof cavity. The cover plate 16 is detachably connected to the rear cover 12. Exemplarily, the cover plate 16 includes a first connecting hole 161, the rear cover 12 includes a second connecting hole 122, and the body 14 includes a third connecting hole 142. Along the second direction Y, the first connecting hole 161, the second connecting hole 122, and the third connecting hole 142 are arranged opposite to each other. The handle 10 includes a first connector 17, which can pass through the first connecting hole 161, the second connecting hole 122, and the third connecting hole 142 in sequence along the second direction Y to connect the cover plate 16, the rear cover 12, and the body 14.
[0061] In some embodiments, the cover plate 16 includes two second connecting portions 162 arranged at intervals along a third direction Z. Each second connecting portion 162 includes a first protrusion 1621 and a second protrusion 1622 connected together. The first protrusion 1621 extends along a second direction Y, and the second protrusion 1622 extends along a first direction X. The rear cover 12 includes a connecting groove 120, and the first protrusion 1621 can be disposed in the connecting groove 120 to ensure that the cover plate 16 can accurately cover the opening of the mounting groove 121.
[0062] In some embodiments, see Figure 8 , Figure 9 , Figure 10 and combined Figure 5 The rear cover 12 includes a fourth connecting hole 123, the handle cover 13 includes a fifth connecting hole 133, and the handle 10 includes a second connector 18. The fourth connecting hole 123 and the fifth connecting hole 133 are arranged opposite to each other along the second direction Y. The second connector 18 passes through the fourth connecting hole 123 and the fifth connecting hole 133 in sequence, further connecting the rear cover 12 and the body 14. It is understood that the first connector 17 and the second connector 18 can be screws, etc., and this application embodiment does not limit this. In addition, this application embodiment does not limit the number of the aforementioned connecting holes, for example, it can be 1, 2, 3, 4, 5, etc.
