DETAILED DESCRIPTION

[0035] The overall idea of ​​the technical solution provided by the utility model is as follows:

[0036] See also Figures 1 to 13 The hidden handle includes: a handle housing 100, a first receiving groove 110 is provided in the handle housing 100, a sliding groove 120 is provided in the first receiving groove 110, a first limiting portion 121 is provided at the bottom of the sliding groove 120, and a second limiting portion 122 is provided at the side of the sliding groove 120;

[0037] A first handle member 200, the first handle member 200 is disposed in the first receiving groove 110, a limit stopper 210 is disposed at the bottom of the first handle member 200, the limit stopper 210 is used to slide in the sliding groove 120, and a first guiding inclined surface 211 is disposed at the bottom of the limit stopper 210;

[0038] The rotating member 300 is disposed at the lower part of the limit stopper 210. The side of the rotating member 300 is provided with a boss 310. The boss 310 is provided with a second guiding inclined surface 311. The first guiding inclined surface 211 is used to cooperate with the second guiding inclined surface 311 to drive the boss 310 to rotate into the first limiting portion 121 or the second limiting portion 122.

[0039] The first elastic member 400 is disposed between the bottom of the rotating member 300 and the bottom of the handle housing 100 . The first elastic member 400 is used to provide elastic force to move the first handle member 200 away from the first receiving groove 110 .

[0040] In actual use, the handle housing 100 can be installed in the preset groove 1220 of the door and window profile. In order to achieve hiding, the user can push the first handle member 200 into the first receiving groove 110. Figures 2 to 4The first stopper 210 of the first handle member 200 slides downward in the sliding groove 120, and the stopper 210 drives the rotating member 300 arranged below it to move downward and disengage from the second limiting portion 122, and the first elastic member 400 is compressed by the rotating member 300, and the first guide inclined surface 211 provided at the bottom of the stopper 210 contacts the second guide inclined surface 311, thereby driving the boss 310 to rotate to the position of the first limiting portion 121. At this time, the force applied to the first handle member 200 is released, and the first elastic member 400 provides an upward elastic force to the rotating member 300, so that the boss 310 enters the first limiting portion 121 and is clamped in the first limiting portion 121, so that the rotating member 300 is limited and locked, and the first elastic member 400 is compressed and cannot release the elastic force, so the first elastic member 400 cannot make the first handle member 200 disengage from the first receiving groove 110, and the first handle member 200 is hidden in the first receiving groove 110;

[0041] Specifically, the contact between the first guide slope 211 and the second guide slope 311 creates an angle, which acts as a driving force to guide the boss 310 to rotate along the direction of the first guide slope 211. The rotational force comes from the interaction between the force applied by the user to the first handle member 200 and the elastic reaction force of the first elastic member 400.

[0042] When the user needs to use the handle, he can press down the first handle member 200. Figures 5 to 7 At this time, the stopper 210 provided on the first handle member 200 slides downward in the sliding groove 120, and the stopper 210 drives the rotating member 300 provided below it to move downward and disengage from the first limit portion 121. The first guide slope 211 provided on the bottom of the stopper 210 contacts the second guide slope 311, thereby driving the boss 310 to rotate to the position of the second limit portion 122. At this time, please refer to Figures 8 to 10 , the user releases the force on the first handle member 200, and the elastic force of the first elastic member 400 is released, causing the rotating member 300 to move upward, and the boss 310 to move upward in the second limiting portion 122. The rotating member 300 drives the limiting stopper 210 and thus drives the first handle member 200 to move upward, thereby realizing the pop-up of the first handle member 200. At this time, the first handle member 200 will protrude, and the user can grab it to operate the doors and windows. The utility model provides users with a handle solution that can lock the first elastic member 400 when the handle is not needed, so that the first elastic member 400 will not pop out the handle, making the handle hidden, and can be pressed to pop out when the handle is needed, thereby enhancing the user experience. This design realizes the hiding and press-to-pop-out movement of the handle, and provides a handle solution with good experience, easy operation, and flexible use.

[0043] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] See also Figure 4 and Figure 6 The side of the stopper 210 is provided with a guide rib 212, which is used to slide in the second limit portion 122. The guide rib 212 slides in the second limit portion 122, providing precise guidance. This structural design enhances the stability of the stopper 210 sliding in the sliding groove 120, and also optimizes the smoothness of the pop-up and hide of the first handle member 200. The existence of the guide rib 212 enables the first handle member 200 to move accurately along a predetermined path when subjected to user pressure or elastic force.

[0045] See also Figure 4 and Fig.10 The first limiting portion 121 is provided with a third guiding inclined surface 1210, and the third guiding inclined surface 1210 is used to cooperate with the second guiding inclined surface 311 to allow the boss 310 to enter the first limiting portion 121, wherein when the boss 310 enters the first limiting portion 121, the first elastic member 400 is compressed. Specifically, the first guide slope 211 provided at the bottom of the stopper 210 contacts the second guide slope 311, thereby driving the boss 310 to rotate to the position of the first limit portion 121. At this time, the force applied to the first handle member 200 is released, and the first elastic member 400 provides an upward elastic force to the rotating member 300, so that the second guide slope 311 of the boss 310 contacts the third guide slope 1210 upward and enters the first limit portion 121 under the guidance of the third guide slope 1210 and is limited. During the rotation process, due to the interaction between the first guide slope 211 and the second guide slope 311, the boss 310 is forced to move toward the first limit portion 121. When the boss 310 reaches the first limit portion 121, due to the presence of the third guide slope 1210, the boss 310 is guided into the first limit portion 121. Thereby, the boss 310 enters the first limiting portion 121 and is engaged in the first limiting portion 121 , so that the rotating member 300 is limited and locked.

[0046] See also Fig.10, the second limiting portion 122 is a groove body 1220 axially arranged on the side of the sliding groove 120. When the boss 310 enters the groove body 1220, the elastic force of the first elastic member 400 is released, and the rotating member 300 drives the boss 310 to slide in the groove body 1220 under the elastic force of the first elastic member 400, and drives the first handle member 200 to disengage from the first receiving groove 110. Specifically, the second limiting portion 122 is a groove body 1220 axially arranged on the side of the sliding groove 120. When the boss 310 enters the groove body 1220, the elastic force of the first elastic member 400 compressed between the first handle member 200 and the handle housing 100 will be released. This elastic force will drive the rotating member 300 to drive the boss 310 to slide in the groove body 1220, and then drive the first handle member 200 to disengage from the first receiving groove 110. In this way, we can easily make the first handle member 200 pop out and ready for the user to operate.

[0047] See also Fig.13 The side of the first handle member 200 is provided with a third limiting portion 220, and the side of the first receiving groove 110 is provided with a fourth limiting portion 130 matching the third limiting portion 220. The third limiting portion 220 is used for elastic limiting with the fourth limiting portion 130. When the user pushes the first handle member 200 into the first receiving groove 110, the third limiting portion 220 on the side of the first handle member 200 will cooperate with the fourth limiting portion 130 on the side of the first receiving groove 110 for limiting. At this time, the boss 310 enters the first limiting portion 121 and is clamped in the first limiting portion 121, so that the rotating member 300 is limited and locked, and the first elastic member 400 is compressed and cannot release the elastic force. Therefore, the first elastic member 400 cannot provide elastic force to make the first handle member 200 separate from the first receiving groove 110, so that the first handle member 200 is limited and fixed in the first receiving groove 110 by the third limiting portion 220 and the fourth limiting portion 130 to achieve its hiding;

[0048] When the user needs to use the handle, the first handle member 200 can be pressed down with force. Since the third limiting portion 220 and the fourth limiting portion 130 are elastically limited, the third limiting portion 220 will be separated from the fourth limiting portion 130 under the action of the downward pressure of the user. At the same time, the first guiding inclined surface 211 provided at the bottom of the limiting stopper 210 contacts the second guiding inclined surface 311, thereby driving the boss 310 to rotate to the position of the second limiting portion 122. At this time, the user releases the force on the first handle member 200, and the elastic force of the first elastic member 400 is released, so that the rotating member 300 moves upward, and the boss 310 moves upward in the second limiting portion 122, and the rotating member 300 drives the limiting stopper 210 and thereby drives the first handle member 200 to move upward, that is, when the user lets go, the elastic force provided by the first elastic member 400 will cause the first handle member 200 to be automatically popped out, and the elastic force provided by the first elastic member 400 enables the third limiting portion 220 to be separated from the fourth limiting portion 130 when passing through the fourth limiting portion 130 to avoid mutual limitation of the two parties. At this time, the first handle member 200 will have a protruding part, and the user can grab it to operate the doors and windows.

[0049] See also Figure 1The third limiting portion 220 includes a limiting groove 221, the fourth limiting portion 130 includes a second elastic member 131 and a ball member 132, the side of the first accommodating groove 110 is provided with a first slide groove 140 for accommodating the second elastic member 131 and the ball member 132, the first side of the second elastic member 131 is connected to the bottom of the first slide groove 140, the second side of the second elastic member 131 is connected to the ball member 132, and the ball member 132 is used to press against the limiting groove 221 under the elastic force of the second elastic member 131. The second elastic member 131 provides elastic force to the ball member 132, so that when the ball member 132 is pushed into the limiting groove 221, elastic limiting can be achieved. More specifically, when the first handle member 200 is initially pushed into the first receiving groove 110, the ball member 132 moves toward the direction close to the limiting groove 221. When the ball member 132 moves to the position of the limiting groove 221, due to the elastic force applied to it by the second elastic member 131, the ball member 132 will be elastically limited in the limiting groove 221; when the user presses down the first handle member 200, the ball member 132 can be separated from the limiting groove 221. At this time, the first handle member 200 is released, and the first elastic member 40 0 is released, so that the rotating member 300 moves upward, the boss 310 moves upward in the second limiting portion 122, and the rotating member 300 drives the limiting stopper 210 and thus drives the first handle member 200 to move upward, that is, when the user lets go, the elastic force provided by the first elastic member 400 will cause the first handle member 200 to be automatically ejected. At this time, when the ball member 132 passes through the limiting groove 221, the resistance encountered by the ball member 132 when moving in the limiting groove 221 is insufficient in the face of the elastic force of the first elastic member 400. Therefore, the elastic force of the first elastic member 400 will push the ball member 132 to smoothly pass through the limiting groove 221 and break away from the mutual limiting state, thereby realizing that the ball member 132 is separated from the limiting groove 221.

[0050] See also Figure 2 The outer side of the handle housing 100 is provided with an elastic buckle assembly 500, which is designed to have a certain elasticity. In this way, when installing, the user only needs to align and insert the handle housing 100 into the preset groove of the profile, and the elastic buckle assembly 500 will automatically fasten the groove due to its own elastic characteristics. This not only ensures the stability of the handle housing 100, but also simplifies the installation process and improves the efficiency of installation.

[0051] For further information, see Figure 1The elastic buckle assembly 500 includes a buckle 510 and a third elastic member 520. The outer side of the handle housing 100 is provided with a second slide groove 150 for accommodating the buckle 510 and the third elastic member 520. The first side of the third elastic member 520 is connected to the bottom of the second slide groove 150, and the second side of the third elastic member 520 is connected to the buckle 510. Specifically, the preset slot is a groove. When the handle housing 100 is installed in the preset slot, the edge of the slot will apply pressure to the buckle 510, and this pressure will be transmitted to the third elastic member 520 through the buckle 510, so that the third elastic member 520 is compressed. At this time, the buckle 510 is equivalent to forming a "lever" between the edge of the slot and the third elastic member 520, and the third elastic member 520 is compressed to store energy. When the handle housing 100 is completely inserted and positioned in the groove, the pressure of the edge of the groove on the buckle 510 will be removed, the energy stored in the third elastic member 520 will be released, and the third elastic member 520 will try to return to its original state. In this process, the third elastic member 520 releases energy and pushes the buckle 510 to move toward the inside of the groove body, so that the buckle 510 is stuck in the groove body, thereby fixing the handle housing 100 in the preset groove body.

[0052] See also Fig.11 and Fig.12 , the handle housing 100 is further provided with a second receiving groove 160 on one side of the first receiving groove 110, and a second handle piece 600 is installed in the second receiving groove 160, and the second handle piece 600 is rotatably connected to the second receiving groove 160, which means that the second handle piece 600 can rotate around the rotation connection point with the second receiving groove 160, and then the second handle piece 600 can be rotated into the second receiving groove 160 and hidden. This is both beautiful and can protect the second handle piece 600 to prevent misoperation or damage. For example, the rotational connection between the second handle piece 600 and the second receiving groove 160 can be achieved through an axis or a hinge or a similar mechanism. In addition, a toggle portion 610 is provided on one side of the second handle piece 600, and the toggle portion 610 passes through the handle housing 100 and is connected to the sliding member 700, and the toggle portion 610 is used to toggle the sliding member 700, and the sliding member 700 is used to connect the transmission structure of the door and window. Specifically, when the toggle part 610 toggles the sliding member 700, the sliding member 700 moves, thereby driving the transmission structure of the door and window to realize the opening and closing action. This design makes the hidden handle not only have the function of a handle, but also can realize the opening and closing function by driving the transmission structure of the door and window through the second handle member 600, thereby improving the user experience.

[0053] See also Fig.11The sliding member 700 is provided with a toggle groove 710, the toggle portion 610 is connected to the toggle groove 710, and one side of the sliding member 700 is connected to the handle housing 100 through the fourth elastic member 800, and the fourth elastic member 800 is used to make the sliding member 700 return to its original position after being toggled. Specifically, when the toggle portion 610 toggles the sliding member 700, the fourth elastic member 800 will be stretched or compressed; and when the force is removed, the fourth elastic member 800 will use its own elastic force to push the sliding member 700 back to its original position. When the fourth elastic member 800 returns the sliding member 700 to its original position, since the toggle portion 610 is connected to the toggle groove 710 of the sliding member 700, the movement of the sliding member 700 will drive the toggle portion 610, and then the second handle member 600 will also return to its original position. This setting ensures that no matter how the user operates the second handle member 600, the second handle member 600 can always return to its original position, thereby ensuring automatic resetting after operation, reducing the difficulty of use for the user, and improving the convenience of the product.
