[0036] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Example:

[0038] See also Figure 1 , Figure 1 This is a structural diagram of a handle structure 10 provided in an embodiment of the present invention applied to a sliding door 100.

[0039] The embodiment of the present invention provides a handle structure 10 that can be rotated when in a safety state and is not easily damaged. The handle structure 10 can be applied to an opening and closing structure such as a sliding door 100.

[0040] Among them, taking the application of the handle structure 10 to the sliding door 100 as an example, the sliding door 100 includes the above-mentioned handle structure 10, and the sliding door 100 is unlocked by the handle structure 10. The sliding door 100 may also include a door body 20 and a locking mechanism 30. The locking mechanism 30 and the handle structure 10 are both installed on the door body 20. The locking mechanism 30 is connected to the handle structure 10 to drive the locking structure to unlock through the handle structure 10. The sliding door 100 can be used in scenarios such as aircraft and vehicles.

[0041] Since the sliding door 100 adopts the handle structure 10 provided by the embodiment of the present invention, the sliding door 100 also has the characteristics that the handle can be rotated when entering the safety state and the handle is not easily damaged.

[0042] The following will specifically introduce the structural composition, working principle and beneficial effects of the handle structure 10 provided in an embodiment of the present invention.

[0043] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , Figure 2 This is a structural schematic diagram of the handle structure 10 provided by an embodiment of the present invention from a first perspective. Figure 3 This is a structural schematic diagram of the handle structure 10 provided by an embodiment of the present invention from a second viewing angle. Figure 4Schematic diagram of the structure of the operating swing arm 152 of the handle structure 10 provided in an embodiment of the present invention. Figure 5 This is a schematic structural diagram of the stop swing arm 151 of the handle structure 10 provided in an embodiment of the present invention. Figure 3 The direction indicated by the dotted arrow is the first direction.

[0044] The handle structure 10 includes a mounting body 12, a first transmission mechanism 13, an actuator 15 and a safety mechanism 17. The first transmission mechanism 13, the actuator 15 and the safety mechanism 17 are all mounted on the mounting body 12. The first transmission mechanism 13 is used to drive the actuator 15 to move under the drive of the user. The actuator 15 is used to connect with the locking mechanism 30 to move under the drive of the first transmission mechanism 13 and drive the locking mechanism 30 to unlock, so as to open the sliding door 100. The safety mechanism 17 can be switched to a working state or a safety state under the operation of the user. In the working state, the first transmission mechanism 13 and the actuator 15 are connected, and in the safety state, the first actuator 15 and the actuator 15 are disconnected, thereby avoiding accidental opening. Moreover, by disconnecting the connection between the first transmission mechanism 13 and the actuator 15, even if the operator turns the handle without paying attention to the safety state, it is not easy to damage the handle.

[0045] The actuator 15 may include a stopper arm 151 and a manipulating arm 152. The manipulating arm 152 is rotatably connected to the mounting body 12. The stopper arm 151 is also rotatably connected to the mounting body 12. The manipulating arm 152 is configured to connect to the locking mechanism 30. When the manipulating arm 152 rotates in the first direction to the first position 121, it is configured to unlock the locking mechanism 30 of the sliding door 100.

[0046] The first transmission mechanism 13 includes a first handle 131, and the first handle 131 and the safety mechanism 17 are both connected to the installation body 12, wherein the safety mechanism 17 can switch the state to a safety state or a working state under the action of external force, and, in the working state, the safety mechanism 17 connects the stopping swing arm 151 and the operating swing arm 152. In other words, the stopping swing arm 151 and the operating swing arm 152 are connected through the safety mechanism 17, and in the safety state, the safety mechanism 17 disconnects the stopping swing arm 151 and the operating swing arm 152. In other words, the safety mechanism 17 releases the connection between the stopping swing arm 151 and the operating swing arm 152 under the operation of the user.

[0047] The first handle 131 is also connected to the stop swing arm 151. The user can operate the first handle 131 so that the first handle 131 drives the stop swing arm 151 to rotate under the action of external force, and in the working state, the stop swing arm 151 drives the operating swing arm 152 to rotate the first position 121 along the first direction.

[0048] In this way, by setting a safety mechanism 17 that can connect the stopping swing arm 151 and the operating swing arm 152, and can also release the connection between the stopping swing arm 151 and the operating swing arm 152, in the working state, the operator can drive the operating swing arm 152 to move in sequence through the first handle 131, the stopping swing arm 151 and the safety mechanism 17, and then drive the locking mechanism 30 to unlock. In the safety state, the safety mechanism 17 disconnects the connection between the stopping swing arm 151 and the operating swing arm 152, so that the operator can rotate the first handle 131. Even if the operator rotates the first handle 131 without paying attention to the safety state, it is not easy to damage the first handle 131.

[0049] Please continue reading Figure 3 、 Figure 4 and Figure 5 A first stop hole 1522 may be provided on the operating swing arm 152, and correspondingly, a second stop hole 1512 may also be provided on the stop swing arm 151, and the safety mechanism 17 may include a stop pin 171. The process of the safety mechanism 17 switching to the working state is that the stop pin 171 enters the first stop hole 1522 and the second stop hole 1512 at the same time under the action of external force, so as to connect the stop swing arm 151 and the operating swing arm 152 through the stop pin 171, and the process of the safety mechanism 17 switching to the safety state is that the stop pin 171 exits the first stop hole 1522 and the second stop hole 1512 at the same time under the action of external force, so as to disconnect the connection between the stop swing arm 151 and the operating swing arm 152, so that the user can rotate the first handle 131 in the safety state.

[0050] In this way, the stopping swing arm 151 and the operating swing arm 152 are connected by placing the stop pin 171 into the first stop hole 1522 and the second stop hole 1512, and the connection between the stopping swing arm 151 and the operating swing arm 152 is disconnected by taking out the stop pin 171 from the first stop hole 1522 and the second stop hole 1512. The connection and disconnection method is simpler and the stroke is shorter, which is convenient for users to operate.

[0051] Furthermore, the actuator 15 may also include a rotating pin 153, and the stopping swing arm 151 and the operating swing arm 152 are both rotatably connected to the installation body 12 through the rotating pin 153, that is, the rotating pin 153 is installed on the installation body 12, and the stopping swing arm 151 and the operating swing arm 152 are both rotatably connected to the rotating pin 153.

[0052] A first sliding hole 1523 communicating with the first stop hole 1522 may also be provided on the operating swing arm 152, and the first stop hole 1522 and the first sliding hole 1523 are both extended along the length direction of the operating swing arm 152, or in other words, the first stop hole 1522 and the first sliding hole 1523 are two sections of a bar hole, and the second stop hole 1512 is extended along the length direction of the stop swing arm 151, and a second sliding hole 1513 communicating with the second stop hole 1512 may also be provided on the stop swing arm 151, the second sliding hole 1513 is an arc-shaped bar hole whose axis is the rotating pin 153, and the second sliding hole 1513 is an arc-shaped bar hole whose center is the rotating pin 153.

[0053] Under the action of external force, the stop pin 171 can enter the first sliding hole 1523 from the first stop hole 1522, and at the same time enter the second stop hole 1512 from the second stop hole 1512, so that the safety mechanism 17 is in a safety state, so that when the stop swing arm 151 rotates under the drive of the first transmission mechanism 13, the stop pin 171 slides in the second sliding hole 1513 to disconnect the connection between the stop swing arm 151 and the operating swing arm 152. In other words, the first stop hole 1522 and the second stop hole 1512 overlap, and the first sliding hole 1523 and the second sliding hole 1513 partially overlap. When the stop pin 171 is located in the first stop hole 1522 and the second stop hole 1512, since the first stop hole 1522 and the second stop hole 1512 are respectively extended along the length direction of the operating swing arm 152 and the stop swing arm 151, when the stop swing arm 151 rotates relative to the mounting body 12, the side wall of the second stop hole 1512 will push the stop pin 171, and the stop pin 171 will be locked. The pin 171 can further push the operating swing arm 152 to realize the connection between the operating swing arm 152 and the stopping swing arm 151. When in the insurance state, the stopping pin 171 is located in the second sliding hole 1513 and the first sliding hole 1523. Since the second sliding hole 1513 is an arc-shaped strip hole and its axis is the rotating pin 153, when the stopping swing arm 151 rotates around the rotating pin 153, the stopping pin 171 slides in the second sliding hole 1513, thereby realizing the effect that the stopping swing arm 151 can rotate but does not drive the operating swing arm 152 to rotate.

[0054] In this way, by moving the stop pin 171 to the first stop hole 1522 or the first sliding hole 1523, the connection between the stop swing arm 151 and the operating swing arm 152 is maintained or released. The method is simpler, the stroke is shorter, and it is convenient for users to operate.

[0055] It should be noted that in other embodiments, the safety mechanism 17 can also switch the working state and the safety state by driving the stop pin 171 to insert or withdraw from the corresponding holes on the stop swing arm 151 and the operating swing arm 152, or by clamping the stop swing arm 151 and the operating swing arm 152, or by simultaneously covering the stop swing arm 151 and the operating swing arm 152 to achieve the connection and contact connection between the stop swing arm 151 and the operating swing arm 152.

[0056] Please continue reading Figure 4 The operating swing arm 152 may also be provided with an assembly hole 1521, which is connected to the first stop hole 1522, and the diameter of the assembly hole 1521 is larger than the first stop hole 1522 and the first sliding hole 1523, so that the stop pin 171 can be installed from the assembly hole 1521 into the first stop hole 1522 or the first sliding hole 1523, thereby improving assembly efficiency.

[0057] Please continue reading Figure 3 and Figure 5 The operating swing arm 152 is rotated from the first position 121 to the second position 122 along a second direction opposite to the first direction to release the locking mechanism 30. In other words, the operating swing arm 152 has two states, namely, a first state in which the locking mechanism 30 is unlocked when the operating swing arm 152 moves along the first direction to the first position 121, and a second state in which the locking mechanism 30 is released when the operating swing arm 152 moves along the second direction to the second position 122. The second stop hole 1512 is located at one end of the second sliding hole 1513, and the second sliding hole 1513 extends along the second direction. In this way, when the stop pin 171 is located in the second stop hole 1512, the stop swing arm 151 can drive the stop pin 171 through the side wall of the second stop hole 1512, and then the stop pin 171 drives the operating swing arm 152 to rotate along the second direction to the second position 122. Alternatively, when the stop pin 171 is located in the second sliding hole 1513, the stop swing arm 151 can also drive the stop pin 171 through the end of the second sliding hole 1513 where the second stop hole 1512 is located, and then the stop pin 171 drives the operating swing arm 152 to rotate along the second direction to the second position 122. In this way, the stop swing arm 151 drives the operating swing arm 152 to return to the second state.

[0058] Please refer to the following Figure 3The actuator 15 may further include a reset elastic member 155 connected to the stop swing arm 151. The reset elastic member 155 is elastic. The stop swing arm 151 is configured to have a tendency to rotate in the second direction under the elastic force of the reset elastic member 155. After the user pulls the first handle 131 to drive the stop swing arm 151 to rotate in the first direction, and when the user does not operate the first handle 131, the reset elastic member 155 will drive the stop swing arm 151 to rotate in the second direction, thereby driving the operating swing arm 152 to rotate to the second position 122, so that the operating swing arm 152 returns to the second state.

[0059] Furthermore, the first transmission mechanism 13 may also include a first transmission swing arm 132, which is rotatably connected to the mounting body 12 and connected to the first handle 131. One end of the transmission swing arm rests on the stop swing arm 151. When the user operates the first handle 131, the first transmission swing arm 132 can be driven to push the stop swing arm 151 to rotate along the first direction. In this way, the first transmission mechanism 13 is connected to the stop swing arm 151 by resting on it. When the stop swing arm 151 acts in the first direction under the action of other forces, it will not drive the first transmission swing arm 132 to move. Even if a user operates the first handle 131 at the same time, it is not easy to damage the first handle 131.

[0060] See also Figure 3 and Figure 6 , Figure 6 This is a schematic structural diagram of the stop pin 171 of the handle structure 10 provided in an embodiment of the present invention.

[0061] The stop pin 171 includes a pin rod 1712 and a stop connecting portion 1713, and a connecting groove 1715 is provided on the stop connecting portion 1713. When assembling the stop pin 171 in the first stop hole 1522 and the first sliding hole 1523, the stop connecting portion 1713 can be placed in the assembly hole 1521 first, and then moved from the assembly hole 1521 to the first stop hole 1522, so that the side wall of the first stop hole 1522 or the first sliding hole 1523 is located in the connecting groove 1715 to complete the assembly of the stop pin 171. The stop pin 171 connected in this way is more stable and less likely to swing relative to the operating swing arm 152.

Figure 8 Schematic diagram of the structure of the safety swing arm 172 of the handle structure 10 provided in an embodiment of the present invention.

[0063] The safety mechanism 17 may also include a safety swing arm 172 rotatably connected to the mounting body 12, and a first safety connection hole 1721 is provided on the safety swing arm 172, and the first safety connection hole 1721 is an arc-shaped bar hole whose axis is the rotation pin 153, and the stop pin 171 is movably inserted into the first safety connection hole 1721. The safety swing arm 172 can drive the stop pin 171 to enter the first stop hole 1522 and the second stop hole 1512 at the same time under the action of external force, or drive the stop pin 171 to enter the first sliding hole 1521 at the same time. 523 and the second sliding hole 1513, in other words, by rotating the safety swing arm 172, the first safety connecting hole 1721 is swung. Since the first safety connecting hole 1721 is an arc-shaped bar hole whose axis is the rotating pin 153, when the stop swing arm 151 drives the operating swing arm 152 to rotate, or when other external forces drive the operating swing arm 152 to rotate, the stop pin 171 can rotate with the operating swing arm 152 and slide relative to the safety swing arm 172 in the first safety connecting hole 1721, thereby reducing the influence of the safety mechanism 17 on the rotation of the operating swing arm 152.

[0064] The safety mechanism 17 may further include a safety push block 173 slidably connected to the mounting body 12, the safety push block 173 is provided with a connecting paddle 1731, the connecting paddle 1731 is provided with a paddle protrusion 1732, the safety swing arm 172 is further provided with a second safety connection hole 1722 which is a bar hole, the paddle protrusion 1732 is arranged in the second safety connection hole 1722, and can slide in the second safety connection hole 1722, that is, the length of the second safety connection hole 1722 is greater than the paddle protrusion 1732 The user can drive the safety swing arm 172 to rotate by moving the safety push block 173, and by setting a larger second safety connecting hole 1722 connected to the paddle protrusion 1732, so that when the stop swing arm 151 slides relative to the safety swing arm 172 in the first safety connecting hole 1721 and drives the safety swing arm 172 to swing, the paddle protrusion 1732 moves relative to the safety swing arm 172 in the second safety connecting hole 1722, without affecting the position of the safety push block 173, thereby improving the stability of the handle structure 10.

[0065] Please continue reading Figure 3 、 Figure 4 、 Figure 9 and Figure 10 , Figure 9 This is a schematic structural diagram of the second transmission swing arm 191 of the handle structure 10 provided in an embodiment of the present invention. Figure 10 A schematic structural diagram of the second transmission swing arm 191 of the handle structure 10 provided in an embodiment of the present invention from another perspective.

[0066] The handle structure 10 may further include a second transmission mechanism (not shown in the figure), which may include a second handle (not shown) and a second transmission swing arm 191 connected to each other. The second transmission swing arm 191 is rotatably connected to the rotating pin 153. The operating swing arm 152 may also be provided with a third sliding hole 1525. The third sliding hole 1525 is an arc-shaped strip hole with the axis of the rotating pin 153. A transmission protrusion 1912 is provided on the second transmission swing arm 191. The transmission protrusion 1912 is located in the third sliding hole 1525 to connect the second transmission swing arm 191 and the operating swing arm 152. When the user operates the second handle, the second transmission swing arm 191 is configured to rotate in the first direction under the drive of the second handle, and the transmission protrusion 1912 abuts against one end of the third sliding hole 1525 to drive the operating swing arm 152 to rotate in the first direction. When the operator drives the second transmission swing arm 191 to rotate in the second direction through the second handle, the transmission protrusion 1912 slides in the third sliding hole 1525.

[0067] In this way, the operating swing arm 152 is driven to rotate by the second transmission swing arm 191 independent of the stop swing arm 151, so that even when the safety mechanism 17 is in the safety state, the second handle can independently drive the operating swing arm 152 to rotate, and by setting the third sliding hole 1525 with the axis as the rotating pin 153 and an arc-shaped strip hole, the second transmission swing arm 191 can only drive the operating swing arm 152 to rotate along the first direction. When the second transmission swing arm 191 rotates along the second direction opposite to the first direction, it cannot drive the operating swing arm 152 to rotate along the second direction, which does not affect the rotation of the operating swing arm 152 to the second position 122.

[0068] Furthermore, a first linkage block 1515 may be protruding from the stop swing arm 151. The first linkage block 1515 abuts against the second transmission swing arm 191. When the stop swing arm 151 rotates in the second direction, the first linkage block 1515 can push the second transmission swing arm 191 to rotate, thereby driving the second transmission swing arm 191 to reset via the stop swing arm 151. In other words, when the first linkage block 1515 drives the second transmission swing arm 191 to rotate in the second direction, the driving method is pushing. Conversely, when the second transmission swing arm 191 rotates in the second direction, the second transmission swing arm 191 does not drive the stop swing arm 151 to rotate. Moreover, when the second transmission swing arm 191 rotates in the first direction, the first linkage block 1515 can drive the stop swing arm 151 to rotate in the first direction. Similarly, the second transmission swing arm 191 can only operate the stop swing arm 151 in one direction, thereby reducing the influence of the second transmission swing arm 191 on the movement of the stop swing arm 151.

[0069] Correspondingly, one end of the first transmission swing arm 132 of the first transmission mechanism 13 rests on the stop swing arm 151 and can only drive the stop swing arm 151 to rotate along the first direction, reducing the influence of the first transmission swing arm 132 on the movement of the stop swing arm 151.

[0070] The working principle of the handle structure 10 provided in the embodiment of the present invention is:

[0071] When the safety mechanism 17 is switched to the safety state, the user pushes the safety push block 173, and the paddle protrusion 1732 on the connecting paddle 1731 moves in the second safety connecting hole 1722 on the safety swing arm 172, thereby driving the safety swing arm 172 to rotate, so that the stop pin 171 provided in the first safety connecting hole 1721 enters the first stop hole 1522 and the second stop hole 1512 at the same time under the rotation action of the safety swing arm 172. At this time, the user can drive the first transmission swing arm 132 through the first handle 131, and push the stop swing arm 151 to rotate along the first direction through the first transmission swing arm 132. The stop swing arm 151 passes through the first stop hole 1721 and moves along the first direction. 1522 and the stop pin 171 in the second stop hole 1512 drive the operating swing arm 152 to rotate from the first position 121 along the first direction to the second position 122, so as to drive the locking mechanism 30 to unlock, and since the second transmission swing arm 191 is connected to the operating swing arm 152 through the transmission protrusion 1912 set in the third sliding hole 1525, when the operating swing arm 152 rotates along the first direction, it will not drive the operating swing arm 152 to rotate, and since the stopping swing arm 151 is supported by the first linkage block 1515 at one end of the second transmission swing arm 191 in the first direction, the stopping swing arm 151 will not drive the second transmission swing arm 191 to rotate when it rotates along the first direction.

[0072] When the safety mechanism 17 switches to the working state, the user pushes the safety push block 173, and the paddle protrusion 1732 on the connecting paddle 1731 moves in the second safety connecting hole 1722 on the safety swing arm 172, thereby driving the safety swing arm 172 to rotate, so that the stop pin 171 passing through the first safety connecting hole 1721 enters the first sliding hole 1523 and the second sliding hole 1513 at the same time under the rotation action of the safety swing arm 172. At this time, the user can rotate the first handle 131, but when the first handle 131 drives the first transmission swing arm 132 and pushes the stop swing arm 151 to rotate along the first direction through the first transmission swing arm 132, the stop pin 171 slides relative to the stop swing arm 151 in the second sliding hole 1513, so that when the user rotates the handle without paying attention to the safety state, it is not easy to damage the handle.

[0073] In summary:

[0074] The embodiment of the present invention provides a handle structure 10, which has the characteristics of being rotatable when entering a safety state and being less likely to be damaged.
