DETAILED DESCRIPTION

[0035] In order to make the purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the protection scope of the present application.

[0036] Reference Figures 1 to 5, the application provides a kind of intelligent lock handle lock head clutch device, it includes: handle 101, joint 104 is embedded in it;The joint 104, lock head assembly is movably embedded in it;Keyhole located at the first end of lock head assembly is exposed to the surface of handle 101;The second end of the lock head assembly is connected to the clutch 109 for triggering lock switch by elastic telescopic transmission part, flexible transmission is realized by the above-mentioned elastic telescopic transmission part.

[0037] In the embodiment, the above structure solves the problem of hard connection transmission of the lock cylinder of the conventional door lock with handle, which is rigid and easy to damage the lock cylinder during long-term use or improper force. By the above structure of the application, the elastic telescopic transmission part is used to connect the lock head assembly and the clutch, and flexible transmission is realized. For example, when the user turns the handle too hard, the elastic telescopic transmission part can buffer this part of impact force, and avoid the force being directly and rigidly transmitted to the key components of the lock cylinder, such as the clutch 109 for triggering the lock switch. It is equivalent to adding a "shock absorber" in a hard connection mechanical structure, which can effectively reduce the damage of the lock cylinder mechanical components caused by external impact, such as wear, deformation and other damage. On the other hand, due to the reduction of damage risk caused by rigid transmission, the overall service life of the lock cylinder can be significantly prolonged. For example, the hard connection transmission door lock may have problems such as unlocking difficulty due to lock cylinder wear after frequent use for several years. While the intelligent lock handle lock head clutch device with flexible transmission can greatly reduce the probability of lock cylinder failure under the same use frequency. The above elastic telescopic transmission part can also make the user feel softer when turning the handle to unlock or lock, and can bring better user experience.

[0038] In the following, a kind of intelligent lock handle lock head clutch device in each example embodiment of the application will be further described.

[0039] In the embodiment of the application, an intelligent lock handle lock head clutch device, wherein the elastic telescopic transmission part includes a sliding pin 105, a first spring 106, a clutch block 107 and a second spring 108;The lock head assembly is in abutment with one end of the sliding pin 105 through a rotatable slope surface 131, and the second end of the sliding pin 105 is connected with the first end of the clutch block 107 through the first spring 106;The cross section of the clutch block 107 is in a non-circular state, and the clutch 109 is provided with a sink 191 with the same cross-sectional shape as the clutch block 107.

[0040] When the lock is opened, the clutch block 107 sinks into the sink 191, otherwise, the clutch block 107 is separated from the sink 191. Specifically, when the key is inserted to open the lock, in the process of turning the key, the above-mentioned lock head assembly is driven to rotate, the lock head assembly pushes the sliding pin 105 through the rotating slope, the sliding pin 105 pushes the first spring 106 to compress, when the pushing force of the first spring 106 and the second spring 108 reaches balance, at this time, continue to turn the key, so that the pressure of the first spring 106 is greater than that of the second spring 108, thereby pushing the above-mentioned clutch block 107 until it falls into the sink 191, because the cross section of the clutch block is non-circular, so that it can drive the clutch 109 to rotate when rotating.

[0041] Further, the upper end of the handle 101 is provided with a first screw hole 111, and the corresponding position of the joint 104 is provided with a second screw hole 141, and the joint 104 and the handle 101 are fixedly connected through the screws and the first screw hole 111 and the corresponding second screw hole, which facilitates disassembly, assembly and maintenance.

[0042] In the embodiment of the present application, as shown in Figure 1 and Figure 3 The lock head assembly includes a lock head 102 and a rotating knob 103; the lock head 102 is provided with a key hole at the first end and a driving block 121 at the second end; the rotating knob 103 is embedded in the first end of the joint 104, and the outer end of the rotating knob 103 is provided with a connecting groove 132, and the driving block 121 is embeddedly connected with the connecting groove 132; the inner end of the rotating knob 103 is provided with a positioning hole in a concentric manner, that is, the positioning hole is located at the center of the rotating knob 103, which is equivalent to being concentrically arranged at the inner end of the rotating knob 103 (embedded in the end of the first end of the joint 104), and a slope 131 is arranged at the outer periphery of the positioning hole; the first end of the joint 104 is internally provided with a positioning column 144 corresponding to the positioning hole; the second end of the joint 104 is provided with a plug hole 142 for plugging the clutch block 107; the plug hole 142 and the first end of the joint 104 are communicated through a through hole 143; the through hole 143 is provided with a sliding pin 105 and a first spring 106, wherein one end of the sliding pin 105 abuts against the slope 131, and the other end of the sliding pin 105 abuts against the clutch block 107 through the first spring 106.

[0043] The driving block 121 of the second end of the lock head 102 is embeddedly connected with the connecting groove 132 of the outer end of the rotating knob 103, so that the transmission between the two is more stable and accurate. For example, during the unlocking process, when the key is inserted into the key hole of the lock head 102 and the lock head is rotated, the driving block 121 can accurately drive the rotating knob 103 to rotate, without transmission deviation caused by loose connection, ensuring the reliability of the unlocking action. The inner end of the rotating knob 103 is provided with a positioning hole in a concentric manner, and the first end of the connector 104 is provided with a positioning column 144 corresponding to the positioning hole. The rotating knob 103 can stably rotate around the central axis in the connector 104. Like the concentric cooperation of the shaft and the hub of the wheel, the eccentric shaking of the rotating knob 103 during rotation can be effectively avoided, thereby improving the structural stability of the entire lock head assembly and reducing abnormal wear and failure caused by component shaking. The one end of the sliding pin 105 in the through hole 143 is in abutment with the slope surface 131 of the inner end of the rotating knob 103, and the other end of the sliding pin 105 is in abutment with the clutch block 107 through the first spring 106. When the rotating knob 103 rotates, the slope surface 131 can cleverly push the sliding pin 105 to move in the through hole 143. During the unlocking process, according to the angle of rotation of the rotating knob 103, the slope surface 131 can gradually push the sliding pin 105, and then control the position of the clutch block 107 through the first spring 106, so as to realize the conversion of the clutch state. Compared with the traditional clutch device, this design can more finely control the clutch process.

[0044] Further, the cross section of the clutch block 107 is square, and the corresponding sink groove 191 and the insertion hole 142 are also square.

[0045] The cross section of the clutch block 107 is square, and the corresponding sink groove 191 and the insertion hole 142 are also square, so as to prevent the clutch block 107 from rotating randomly in the insertion hole 142, and ensure the stability of the clutch block 107 during the axial movement. The accuracy and stability of the clutch action of the clutch block 107 are improved, which helps to realize more reliable lock core clutch control.

[0046] The first spring 106 plays a buffering role between the sliding pin 105 and the clutch block 107. When external force acts on the lock head assembly, for example, the user quickly rotates the handle or is subjected to external impact, the spring can absorb and buffer this part of energy. For example, when the user rotates the rotating knob 103 too hard, the sliding pin 105 will be subjected to a large pushing force of the slope surface 131, and the first spring 106 can buffer this pushing force, so as to avoid damage to the clutch block 107 due to excessive impact force, and also reduce the impact force on the entire lock core structure, further protecting the internal components.

[0047] It should be noted that by relatively combining the non-circular clutch block 107 and the sink 191, the clutch block 107 can drive the clutch 109 to rotate through the sink 191, so that the clutch 109 can further realize the operation of opening and closing the lock. The cross section of the clutch block 107 can be preferably square, pentagonal, hexagonal, semicircular or elliptical, etc.

[0048] In the embodiments of the present application, as shown in Figure 1 、 Figure 4 and Figure 5 , the clutch block 107 is provided with a receiving hole 171 at one end thereof towards the clutch 109, and the second spring 108 is partially located in the receiving hole 171. Through the receiving hole, a part of the second spring 108 is located in the receiving hole 171, which not only saves space and is beneficial to miniaturization of the device, but also enables the second spring 108 to be stable and not to be offset.

[0049] In the embodiments of the present application, the clutch 109 has an automatic reset structure (not shown in the figure). Through the automatic reset structure, when the door is closed, the lock tongue will be retracted in the spring. During this process, the lock tongue will push the clutch 109 in the opposite direction, and at this time, the clutch is not connected with the clutch block 107, so it will not affect the lock cylinder part. When the lock tongue is not completely ejected, that is, the clutch 109 is not reset, at this time, since the sink 191 of the clutch 109 is the same shape as the clutch block 107 and is not circular, the clutch block 107 cannot fall into the sink 191, so it cannot be opened by the key. The lock of the device has a physical error correction function, and the key can be used to open the lock correctly after the clutch 109 is completely reset.

[0050] It should be further noted that through the above-mentioned manner, the intelligent lock handle lock head clutch device of the present application can also combine the function of the electronic lock. When the clutch block 107 cannot fall into the sink 191, the alarm function can be realized through the sensor or other elements to remind the user that the lock is not reset.

[0051] In the embodiments of the present application, the rotating knob 103 is provided with a limiting protrusion, and the first end of the joint 104 is internally provided with a limiting groove, and the limiting protrusion is located in the limiting groove (not shown in the figure). The limiting protrusion is radially arranged at the end of the rotating knob 103 towards the joint 104, and a limiting groove is correspondingly arranged in the first end of the joint 104, for limiting the angle of rotation of the key. When the key is turned to the corresponding position, the limiting protrusion reaches the edge of the limiting groove and is blocked by the groove wall of the limiting groove and cannot continue to rotate forward. The principle of forward rotation is the same.

[0052] The intelligent lock handle clutch device of the application is an intelligent lock accessory with a pure physical structure, and this part of structure does not need to use electronic devices or corresponding software, which can reduce the failure rate, and the intelligent lock handle clutch device of the application also has the advantages of simple structure and low cost.

[0053] It should be noted that the temperature state needs to be matched with a temperature sensor, such as a temperature sensing resistor and the like, and the temperature sensor and the application circuit are conventional technical means, which will not be described here.

Therefore, the appended claims are intended to include the preferred embodiments and all changes and modifications falling within the scope of the embodiments of the application.
