Description

Technical Field

[0001] This utility model relates to the field of smart padlock technology, specifically to a connection structure for smart padlocks. Background Technology

[0002] Smart padlocks are intelligent upgrades of traditional padlocks, integrating electronic identification technology, wireless communication, and mechanical lock body structure to achieve keyless unlocking, remote management, and multiple protection functions. Their core structure can be divided into four parts: the lock body and shank, the intelligent identification module, the electronic control system, and the energy and battery life system. The shank structure is commonly U-shaped. In existing smart padlocks, the conductive contact piece is one of the key components of the electronic control system, primarily responsible for transmitting the switch status signal indicating whether the shank is inserted into the padlock. When the shank is inserted into the padlock, and both ends of the contact ball are in contact with the two conductive contact pieces, the conductive contact pieces form a path through the electronic control system. The electronic control system drives the motor, which locks the locking groove of the shank, thus achieving the locking function of the lock.

[0003] However, the contact reliability between the conductive contact piece and the contact ball of the lock beam is poor under long-term use or vibration environment in existing smart padlocks, which affects the stability and reliability of smart padlocks. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connection structure for intelligent padlocks. It achieves four-point contact between the contacting holes on two contact plates and the cylindrical portion of the contact ball head, and one-point contact between the elastic baffle and the arc-shaped portion of the contact ball head. This results in five-point contact between the conductive contact piece and the contact ball head. The elastic deformation of the two contact plates, along with the contacting holes, constrains the contact ball head, ensuring a firm and reliable connection between the contact ball head and the conductive contact piece, thus improving the stability and reliability of the intelligent padlock.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a connection structure for a smart padlock, comprising contact ball heads disposed at both ends of the lock beam and two conductive contact pieces disposed within the housing of the smart padlock, wherein the two conductive contact pieces are electrically connected to the controller in the smart padlock, and the two contact ball heads are detachably in contact with the conductive contact pieces;

[0006] The conductive contact piece has a snap-fit ​​plate at each end on one side. The snap-fit ​​plate has a snap-fit ​​hole for accommodating the side of the contact ball head. The side of the contact ball head contacts the inner edge of the snap-fit ​​hole. The side of the conductive contact piece has an elastic baffle. The elastic baffle is electrically connected to the snap-fit ​​plate. The elastic baffle can be separated from the end of the contact ball head.

[0007] The snap-fit ​​plate includes a support portion connected to the conductive contact piece and a snap-fit ​​portion for snapping the contact ball head. The two snap-fit ​​portions are symmetrically arranged in a hyperbolic shape, and the snap-fit ​​hole is disposed through the snap-fit ​​portion.

[0008] The contact ball head includes an arc-shaped portion, a cylindrical portion, and a conical portion connected in sequence. The cylindrical portion contacts the upper and lower sides of the two snap-fit ​​holes, respectively, and the arc-shaped portion contacts the elastic baffle.

[0009] The outer diameter of the column section is smaller than the outer diameter of the lock beam body.

[0010] The conductive contact piece and the snap-fit ​​plate are integrally stamped together, and the snap-fit ​​plate is made of stainless steel or brass.

[0011] One or more technical solutions proposed in this application have at least the following technical effects:

[0012] (1) The contact ball head is in four-point contact with the cylindrical part of the contact ball head through the snap-fit ​​holes on the two snap-fit ​​plates, and in one-point contact with the arc part of the contact ball head through the elastic baffle, so that the conductive contact piece is in five-point contact with the contact ball head. Under the elastic deformation of the two snap-fit ​​plates, the contact ball head is constrained through the snap-fit ​​holes, and the contact between the contact ball head and the conductive contact piece is firm and reliable, which improves the stability and reliability of the smart padlock.

[0013] (2) The two snap-fit ​​plates have symmetrical snap-fit ​​parts in a hyperbolic shape to guide the contact ball head into the snap-fit ​​hole, making the connection between the contact ball head and the conductive contact piece more convenient and reliable.

[0014] (3) The elastic baffle is movably set in the guide groove through the elongated hole, thereby realizing the adjustment of the position of the elastic baffle. The elastic baffle is fastened to the snap plate by bolts. The maintenance of the contact ball head and the conductive contact piece does not require replacement of parts, and the maintenance is convenient and quick. The meshing action of tooth surface one and tooth surface two makes the fixing of the elastic baffle more firm and reliable. Attached Figure Description

[0025] In one embodiment, see Figures 1-6A connection structure for a smart padlock includes contact ball heads 1 disposed at both ends of the lock beam and two conductive contact pieces 2 disposed inside the smart padlock housing. The two conductive contact pieces 2 are electrically connected to the controller in the smart padlock, and the two contact ball heads 1 are detachably in contact with the conductive contact pieces 2.

[0026] Furthermore, each end of one side of the conductive contact piece 2 is provided with a snap-fit ​​plate 21. The snap-fit ​​plate 21 is provided with a snap-fit ​​hole 2121 for accommodating the side of the contact ball head 1. The side of the contact ball head 1 contacts the inner edge of the snap-fit ​​hole 2121. The side of the conductive contact piece 2 is provided with an elastic baffle 22. The elastic baffle 22 can be separated from the end of the contact ball head 1. Specifically, the two snap-fit ​​plates 21 are elastically joined together to constrain the contact ball head 1 in the snap-fit ​​hole 2121. At this time, the constrained contact ball head 1 abuts against the elastic baffle, so that the elastic baffle makes firm contact with the contact ball head 1 under elastic deformation.

[0027] It is understood that the conductive contact piece 2 has a guide groove 23 on its side, one end of the elastic baffle 22 is slidably disposed in the guide groove 23, the other end of the elastic baffle 22 is in contact with the end of the contact ball head 1, and the conductive contact piece 2 is provided with bolts 24 for fixing the elastic baffle 22.

[0028] Specifically, the side of the elastic baffle 22 is provided with an elongated hole 222, and the guide groove 23 is provided with an internal threaded hole 231. The bolt 24 passes through the elongated hole 222 and is threadedly connected to the internal threaded hole 231.

[0029] The guide groove 23 is provided with a toothed surface 232, and the bottom side of the elastic baffle 22 is provided with a toothed surface 221. The toothed surface 232 and the toothed surface 221 mesh. It can be understood that the combination of the toothed surface 232 and the toothed surface 221 prevents the elastic baffle from sliding in the guide groove 23 and makes the contact between the elastic baffle and the conductive contact piece 2 good.

[0030] The conductive contact piece 2 has a through mounting hole 25 on its side, and the conductive contact piece 2 is installed inside the housing of the smart padlock through the mounting hole 25.

[0031] Furthermore, bolt 24 is an anti-slip bolt 24, which prevents bolt 24 from loosening, making the connection between the elastic baffle and the guide groove 23 of the conductive contact piece 2 more secure and reliable.

[0032] Specifically, the snap-fit ​​plate 21 includes a support portion 211 connected to the conductive contact piece 2 and a snap-fit ​​portion 212 for snapping the contact ball head 1. The two snap-fit ​​portions 212 are symmetrically arranged in a hyperbolic shape, and the snap-fit ​​hole 2121 is provided through the snap-fit ​​portion 212.

[0033] The contact ball head 1 includes an arc-shaped part 11, a cylindrical part 12 and a conical part 13 connected in sequence. The cylindrical part 12 contacts the upper and lower sides of the two snap-fit ​​holes 2121 respectively, and the arc-shaped part 11 contacts the elastic baffle 22.

[0034] Understandably, the outer diameter of the column face 12 is smaller than the outer diameter of the lock beam body, making it easier for the lock beam body to insert into the smart padlock and resulting in a more compact size.

[0035] Furthermore, the conductive contact piece 2 and the snap-fit ​​plate 21 are integrally stamped and formed. The snap-fit ​​plate 21 is made of stainless steel or brass, and the elastic baffle is also made of stainless steel or brass.

[0036] The specific working process of this utility model:

[0037] In use, the lock beam is inserted into the smart padlock along the housing. When the contact ball heads 1 at both ends of the lock beam contact the conductive contact pieces 2, the arc-shaped part 11 of the contact ball head 1 first contacts the snap-fit ​​part 212 of the snap-fit ​​plate 21. Under the external force of the arc-shaped part 11, the snap-fit ​​plate undergoes elastic deformation, clamping the contact ball heads 1 together. The contact ball heads 1 continue to slide along the snap-fit ​​plate 21 until the cylindrical part 12 is embedded in the snap-fit ​​hole 2121 of the snap-fit ​​part 212. The snap-fit ​​plate 21 holds the cylindrical part 12 in place through the snap-fit ​​hole 2121. At this time, the arc-shaped part 11 contacts the elastic baffle 22. Under the pressure of the arc-shaped part 11, the elastic baffle 22... Elastic deformation occurs, and at this time, the cylindrical part 12 of the contact ball head 1 contacts the upper and lower sides of the two locking holes 2121 respectively, and the arc part 11 of the contact ball head 1 contacts the elastic baffle 22. That is, under the elastic constraint of the locking part 212 on the two locking plates 21, it contacts the contact ball head 1 through five contact points. Since the lock beam is made of metal, the controller analyzes the connection between the lock beam and the two conductive contact pieces 2. If the two ends of the lock beam are connected to the two conductive contact pieces 2 respectively to form a passage, the controller controls the motor to lock the lock beam in the smart padlock through the locking groove, thereby completing the locking operation of the smart padlock.

[0038] The two locking plates 21 make contact with the cylindrical part 12 on the contact ball head 1 at four points through the locking holes 2121 on the two locking plates 21, and make contact with the arc part 11 on the contact ball head 1 at one point through the elastic baffle 22, so that the conductive contact piece 2 makes contact with the contact ball head 1 at five points. Under the elastic deformation of the two locking plates 21, the contact ball head 1 is constrained through the locking holes 2121. The contact between the contact ball head 1 and the conductive contact piece 2 is firm and reliable, which improves the stability and reliability of the smart padlock.

[0039] The two snap-fit ​​plates 21 have symmetrical snap-fit ​​portions 212 in a hyperbolic shape, which guide the contact ball head 1 into the snap-fit ​​hole 2121, making the connection between the contact ball head 1 and the conductive contact piece 2 more convenient and reliable.

[0040] In another embodiment, a guide groove 23 is provided on the side of the conductive contact piece 2, one end of the elastic baffle 22 is slidably disposed in the guide groove 23, and the other end of the elastic baffle 22 contacts the end of the contact ball head 1. A bolt 24 for fixing the elastic baffle 22 is provided on the conductive contact piece 2.

[0041] The elastic baffle 22 has an elongated hole 222 on its side and an internal threaded hole 231 in the guide groove 23. The bolt 24 passes through the elongated hole 222 and is threadedly connected to the internal threaded hole 231.

[0042] The guide groove 23 is provided with a toothed surface 232, and the bottom side of the elastic baffle 22 is provided with a toothed surface 221. The toothed surface 232 meshes with the toothed surface 221.

[0043] The conductive contact piece 2 has a through mounting hole 25 on its side, and the conductive contact piece 2 is installed inside the housing of the smart padlock through the mounting hole 25.

[0044] Bolt 24 is an anti-slip bolt, which makes the connection between the elastic baffle 22 and the conductive contact piece 2 more secure.

[0045] When the smart padlock experiences wear on the contact ball head 1 and the locking hole 2121 due to long-term use, or when there is poor contact between the contact ball head 1 and the locking plate 21, it becomes difficult for the contact ball head 1 and the conductive contact piece 2 to make multi-point contact. In this case, loosen the bolt 24, push the contact ball head 1 to the cylindrical part 12 to make multi-point contact with the locking hole 2121, and then slide the elastic baffle 22 along the guide groove 23 until it contacts the arc part 11 and produces a certain elastic deformation. Then tighten the bolt 24. At this time, the adjustment of the elastic baffle 22 is completed, and the contact ball head 1 makes multi-point contact with the conductive contact piece 2 again. The elastic baffle 22 is movably set in the guide groove 23 through the elongated hole 222, thereby realizing the adjustment of the position of the elastic baffle 22. The elastic baffle 22 is fastened to the locking plate 21 by the bolt 24. The maintenance of the contact ball head 1 and the conductive contact piece 2 does not require the replacement of parts, and the maintenance is convenient and quick. Through the meshing action of the tooth surface 1 232 and the tooth surface 221, the fixing of the elastic baffle 22 is more secure and reliable.
