DETAILED DESCRIPTION

[0032] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0033] In the present disclosure, unless otherwise stated, the directional words used are only for the convenience of describing the present disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation. Therefore, they cannot be understood as limitations on the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.

[0034] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0035] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0036] refer to Figures 1 to 5As shown, the present disclosure provides a door handle structure 1 for electrical secondary equipment, which is used to be installed on the cabinet door of the electrical secondary equipment, including: a handle 10, an electromagnetic lock module 20, a fingerprint recognition module 30 and a positioning module 40, the handle 10 is arranged in a U shape, the electromagnetic lock module 20 is connected to the first end of the handle 10, and is used to lock with a lock slot arranged on the door frame of the electrical secondary equipment, the fingerprint recognition module 30 is installed inside the handle 10, the fingerprint recognition module 30 is electrically connected to the electromagnetic lock module 20, the fingerprint recognition module 30 includes a fingerprint recognition mechanism and a fingerprint collection mechanism connected to each other, and the fingerprint collection mechanism is arranged at The outer surface of the handle 10; the positioning module 40 includes a magnetic part 41 and a buckle 42, the magnetic part 41 includes a first clamping section and a second clamping section 410, the first clamping section is inserted into the second end of the handle 10, the second clamping section 410 is protruding from the second end of the handle 10, and a pin hole is formed on the second clamping section 410, the buckle 42 is clamped in the pin hole and at least partially protrudes from the outer end surface of the second clamping section 410, the second clamping section 410 is used to be clamped in a clamping groove reserved on the cabinet door of the electrical secondary equipment, and the buckle 42 protruding from the outer end surface of the second clamping section 410 is used to clamp with the groove wall of the clamping groove.

[0037] Through the above technical solution, firstly, a fingerprint recognition module 30 and an electromagnetic lock module 20 are arranged on the handle 10, so that after the door handle structure 1 is installed on the door frame of the electrical secondary equipment, the above electromagnetic lock module 20 can be locked in the lock groove on the door frame of the electrical secondary equipment to achieve the locking of the cabinet door, that is, the cabinet door is locked to the periphery of the electrical secondary equipment running with power, thereby avoiding the problem of maintenance personnel accidentally touching the electrical secondary equipment when repairing the related structure and causing three fault accidents of relay protection.

[0038] When it is necessary to open the cabinet door, the maintenance personnel can press their fingers on the fingerprint collection mechanism arranged on the outer surface of the handle 10. After collecting the fingerprint information of the maintenance personnel, the fingerprint collection mechanism transmits it to the fingerprint recognition module 30. The fingerprint recognition module 30 controls the action of the electromagnetic lock module 20 according to the collected information, thereby realizing the opening of the electromagnetic lock module 20 and the cabinet door. There is no need to carry a mechanical key, and the operation is simple and convenient.

[0039] In addition, if Figure 1 , Figure 3As shown, the present disclosure also provides a magnetic member 41 and a buckle 42. When installing the above-mentioned door handle structure 1, the magnetic member 41 can be first inserted into the clamping groove reserved on the cabinet door. At this time, the second clamping section 410 is automatically adsorbed on the cabinet door under the action of magnetic attraction to achieve the positioning of the door handle structure 1 and the cabinet door. Then, the buckle 42 is clamped into the pin hole of the second clamping section 410. The outer end surface of the buckle 42 protrudes from the second clamping section 410 and is clamped with the groove wall of the clamping groove to achieve the fixation of the second clamping section 410 and the clamping groove, thereby achieving the connection between the handle 10 and the cabinet door. In addition, through the above-mentioned connection method, it is also more convenient to disassemble the door handle structure 1 from the cabinet door, thereby facilitating the installation and replacement of the door handle structure 1.

[0040] Optionally, the positioning module 40 may further include an iron sheet 43, which is attached to the outer wall of the second clamping section 410. In this way, the patch can be adsorbed on the outer surface of the magnetic member 41 under the magnetic force of the magnetic member 41, and a higher magnetic field will be generated on the corners and edges of the iron sheet 43, thereby increasing the suction force between the positioning module 40 and the cabinet door, and improving the stability of the connection between the door handle structure 1 and the cabinet door.

[0041] Alternatively, if Figure 1 , Figure 3 As shown, the iron sheet 43 and the buckle 42 are located on the same side wall of the second clamping section 410, and the thickness of the iron sheet 43 is greater than the height of the buckle 42 protruding from the outer end face of the second clamping section 410. In this way, when the second clamping section 410 of the magnetic member 41 is clamped to the clamping groove on the cabinet door, the magnetic member 41 is adsorbed on the groove wall of the clamping groove through the iron sheet 43. Since the thickness of the iron sheet 43 is greater than the height of the buckle 42 protruding from the outer end face of the second clamping section 410, it is possible to avoid the problem that the setting of the buckle 42 interferes with the contact between the iron sheet 43 and the groove wall of the clamping groove, causing the buckle 42 to abut between the groove wall of the clamping groove and the second clamping section 410, affecting the problem of close fit between the iron sheet 43 and the groove wall of the clamping groove.

[0042] In order to improve the stability of the fingerprint collection mechanism, Figure 1 , Figure 2 As shown, a through hole 11 may be formed on the handle 10, and the fingerprint collection mechanism is embedded in the through hole 11, and the outer surface of the fingerprint collection mechanism is lower than the outer surface of the handle 10. Since the outer surface of the fingerprint collection mechanism is lower than the outer surface of the handle 10, the fingerprint collection mechanism is in a relatively closed area, so that the friction or scratches of the fingerprint collection mechanism by external objects can be avoided or reduced, thereby achieving the purpose of improving the stability and service life of the fingerprint collection mechanism.

[0043] In order to further reduce the interference of the fingerprint collection mechanism from the outside, further, as Figure 1 , Figure 2As shown, the door handle structure 1 for electrical secondary equipment also includes a cover plate 50, the through hole 11 has two oppositely arranged hole walls, each hole wall is formed with a slide groove 110 extending along its own length direction, the two sides of the cover plate 50 are respectively embedded in the two slide grooves 110, the cover plate 50 is slidably connected to the handle 10 through the slide groove 110, and is used to cover or open the through hole 11. That is to say, the cover plate 50 is slidably connected to the handle 10 through the slide grooves 110 arranged on the hole walls on both sides. In this way, when the fingerprint collection mechanism does not need to be touched, the cover plate 50 can be pushed to move along the length direction of the slide groove 110, thereby covering the through hole 11 to shield the fingerprint collection mechanism and prevent the fingerprint collection mechanism from being affected or interfered by the outside world such as dust, light, etc., thereby improving the safety, sensitivity and service life of the fingerprint collection mechanism; when the maintenance personnel need to open the cabinet door, the cover plate 50 can be pushed to the open state to expose the through hole 11 and the fingerprint collection mechanism arranged in the through hole 11, and the maintenance personnel can use the fingerprint collection mechanism to realize the unlocking operation of the electromagnetic lock module 20.

[0044] Alternatively, if Figure 2 As shown, a plurality of anti-slip strips 51 arranged at intervals may be formed on the cover plate 50, and each anti-slip strip 51 is arranged to protrude from the outer surface of the cover plate 50. When the maintenance personnel push the cover plate 50 to move along the length direction of the slide groove 110, the plurality of anti-slip strips 51 arranged at intervals can increase the friction between the fingers of the maintenance personnel and the cover plate 50, making it easier to push the cover plate 50.

[0045] The present disclosure does not limit the specific structure and transmission mode of the electromagnetic lock module 20 mentioned above. For example, in an exemplary embodiment provided in the present disclosure, Figure 4 As shown, the electromagnetic lock module 20 includes a first magnetic block 21, a second magnetic block 22, a coil (not shown) and a battery 100. The coil is electrically connected to the battery 100 and is arranged around the outer periphery of the second magnetic block 22. The second magnetic block 22 is sleeved on the outer periphery of the first magnetic block 21. The second magnetic block 22 is used to drive the first magnetic block 21 to the first position or the first magnetic block 21 to the second position, so that the electromagnetic lock module 20 is in a locked state or an unlocked state. The second magnetic member 41 has opposite magnetism when it is powered on and powered off, thereby driving the first magnetic block 21 to reciprocate relative to the second magnetic block 22 to realize the opening or locking of the electromagnetic module.

[0046] like Figure 4 As shown, a non-magnetic isolation layer 23 is further provided on the side of the second magnetic block 22 away from the first magnetic block 21 , and the non-magnetic isolation layer 23 can reduce the interference of the second magnetic block 22 to other electronic components in the door handle structure 1 .

[0047] Alternatively, the electromagnetic lock module 20 may also include a moving iron core, a fixed iron core, a coil, a reset spring, and a battery 100. The coil is electrically connected to the battery 100 and is arranged around the outer periphery of the fixed iron core. The moving iron core and the fixed iron core are arranged relative to each other, and the reset spring is connected between the moving iron core and the fixed iron core. In this way, after the fingerprint collection mechanism collects the user's fingerprint information, after the fingerprint recognition module 30 recognizes and confirms that it is correct, the coil can be controlled to be energized and the direction of the current in the coil can be changed, so that the fixed iron core generates magnetism, and then the moving iron core is attracted to move toward the fixed iron core, thereby reaching an unlocked state. At this time, the cabinet door can be opened; similarly, when the cabinet door needs to be locked, when the fingerprint information is not recognized, the fixed iron core is not energized. At this time, the fixed iron core does not generate magnetic attraction to the moving iron core, and the moving iron core does not move, so that the electromagnetic lock module 20 remains in a locked state.

[0048] Alternatively, in another exemplary embodiment provided by the present disclosure, the electromagnetic lock module 20 may also include a movable magnetic block, a locking magnetic block, a driving mechanism and a battery 100, and the first end of the movable magnetic block and the first end of the locking magnetic block are arranged relative to each other, so that when the magnetism of the first end of the movable magnetic block is the same as the magnetism of the first end of the locking magnetic block, the movable magnetic block and the locking magnetic block repel each other, and the locking magnetic block can be driven to move to a locked state, thereby locking the cabinet door; when the cabinet door needs to be opened, that is, when the fingerprint recognition mechanism detects the correct fingerprint information recognized by the fingerprint collection mechanism, the fingerprint recognition mechanism can control the driving mechanism to drive the movable magnetic block to rotate 180°, so that the second end of the movable magnetic block and the first end of the locking magnetic block are arranged relative to each other, and the magnetism of the second end of the movable magnetic block is opposite to the magnetism of the first end of the locking magnetic block. Under the action of the magnetic attraction force, the locking magnetic block can be driven to move in a direction close to the movable magnetic block, thereby unlocking the electromagnetic lock module 20.

[0049] In order to increase the fault tolerance of the electromagnetic lock module 20, Figure 1 As shown, the door handle structure 1 of the electrical secondary device may also include a mechanical unlocking module 60, which includes an installation box 61, a third magnetic member 41 and a key. The installation box 61 is provided with a keyhole 610, and the key can drive the third magnetic member 41 to move in the installation box 61 in a direction close to or away from the first magnetic block 21, so as to drive the first magnetic block 21 to move to the first position or the second position. In this way, the maintenance personnel can insert the key into the keyhole 610 and rotate it to adjust the position of the first magnetic block 21, thereby realizing the driving of the first magnetic block 21. Not only can the unlocking be realized by fingerprint, but also the unlocking operation can be realized by mechanical key, which is more convenient for the maintenance personnel to perform maintenance work.

[0050] In another exemplary embodiment provided by the present disclosure, the door handle structure 1 for electrical secondary equipment further includes a password recognition module 80, the password recognition module 80 includes a password recognition mechanism and a password input mechanism connected to each other, the password recognition mechanism is arranged inside the handle 10, the password input mechanism is formed on the outer surface of the handle 10, and the password recognition mechanism is electrically connected to the electromagnetic lock module 20. That is, the door handle structure 1 for electrical secondary equipment provided by the present disclosure can also realize the unlocking operation by inputting a password, which further facilitates the unlocking operation of the maintenance personnel.

[0051] Alternatively, if Figure 5 As shown, the door handle structure 1 for electrical secondary equipment may further include a controller 70 and an alarm module 90, and the controller 70 is electrically connected to the alarm module 90 and the fingerprint recognition module 30, respectively. In this way, when the maintenance personnel or other personnel input an incorrect fingerprint during the process of opening the electromagnetic lock module 20, that is, when the fingerprint recognition module 30 cannot recognize the input fingerprint information, the fingerprint information can be sent to the controller 70, and the controller 70 can control the alarm module 90 to alarm, and the relevant maintenance personnel can check the relevant information in time according to the alarm sound, further avoiding the problem of the electrical secondary equipment being accidentally touched.

[0052] It should be noted that the above-mentioned fingerprint recognition module 30 can also include a storage module and a comparison module. The storage module can store fingerprint information with the authority to open the above-mentioned electromagnetic lock module 20. The storage module and the comparison module can be electrically connected to the controller 70 respectively. When the fingerprint collection module collects the fingerprint information of the relevant personnel, the comparison module compares the fingerprint information with the fingerprint information stored in the storage module. When the two are the same, the controller 70 can control the electromagnetic lock module 20 to open. When the two are different, the controller 70 can control the electromagnetic lock module 20 not to open, and control the alarm module 90 to alarm.

[0053] For the implementation embodiment in which the electromagnetic lock module 20 may include a first magnetic block 21, a second magnetic block 22, a coil and a battery 100, the above-mentioned controller 70 may be electrically connected to the battery 100, and the battery 100 may include a first battery 100 and a second battery 100. The controller 70 may respectively control the first battery 100 to be connected or disconnected from the coil, and the second battery 100 to be connected or disconnected from the coil, thereby achieving the purpose of changing the direction of current flow in the coil.

[0054] In an embodiment where the electromagnetic lock module 20 may also include a driving mechanism, the controller 70 may be electrically connected to the driving mechanism and the fingerprint recognition module 30 respectively, and may control the operation of the driving mechanism according to the fingerprint information recognized by the fingerprint recognition module 30 .

[0055] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0056] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0057] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
