Description

Technical Field

[0001] The utility model belongs to the technical field of electronic lock threading, and in particular relates to a door hinge for an electronic lock with continuous power supply through-line. Background Art

[0002] At present, all electronic locks and fingerprint locks on the market adopt two power supply modes: one is dry battery, and the other is lithium battery. There is a risk of power outage at any time during use. At the very least, the user cannot go home (even if the lock factory is equipped with a mechanical key, the power bank cannot solve the need for power supply at any time for the electronic lock), which brings a bad experience to the customer. At worst, the poor fire resistance of the battery brings safety hazards. The weak power supply limits the electronic lock as a security carrier and cannot be equipped with too many other security electronic equipment, such as smoke sensors outside the door, fire alarms, expulsion alarms and other functions, which do not meet people's safety needs. The weak power supply of the electronic lock also makes the network signal poor and the transmission speed slow, making it difficult to truly realize the needs of smart home networking.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0018] See also Figure 1-4 The utility model provides a technical solution: a door hinge with continuous power supply through the wire of an electronic lock, including a through-wire hinge 1 installed in the middle of the door body. Since the electronic lock is generally hidden on one side of the middle part of the inner body, and the through-wire hinge 1 is correspondingly installed on the other side of the door body, and the load-bearing hinge 2 installed at the upper and lower ends of the door body for bearing the weight of the door body, the through-wire hinge 1 bears less weight on the door body, avoiding the situation that the incoming wire harness body 12 is broken due to the large bearing force. The through-wire hinge includes a through-wire hinge leaf 3 installed on the door leaf and a through-wire hinge leaf 3 installed on the door frame, so that the two through-wire hinge leafs 3 can be installed one on the door leaf and the other on the door frame. On the door frame, the other is installed on the side surface of the door body. One end of the wire-passing hinge leaf piece 3 is connected with a hollow shaft 5 through the central axis hole 4 through which the wire harness passes from the inside, so that the wire harness body 12 can be passed from the inside of the hollow shaft 5 to be electrically connected with the electronic lock. The surface of the central axis hole 4 is laterally penetrated with wire-passing holes 6 for allowing the two ends of the wire harness to pass through to the two end surfaces of the wire-passing hinge 1. One end of the wire harness body 12 is passed through the wire-passing hole 6 on one wire-passing hinge leaf piece 3 and passed out from the wire-passing hole 6 on the other wire-passing hinge leaf piece 3, so that the wire harness body 12 can be powered through the wire, so that the electronic lock can be continuously powered;

[0019] The load-bearing hinge 2 includes two load-bearing door leaf pieces 7 installed and connected with the door frame and the door body, which can provide load-bearing support for the door body and reduce the supporting gravity of the over-the-line hinge 1. The load-bearing door leaf pieces 7 are connected through the load-bearing central axis hole 8 with a solid load-bearing shaft 9 that connects the two load-bearing door leaf pieces 7 together to form the load-bearing hinge 2, which is used for the installation of the two load-bearing door leaf blades, and the only difference from the over-the-line hinge 1 is the internal structure of the load-bearing shaft.

[0020] The hollow shaft 5 is provided with an active washer A10 which penetrates into the center position of the surface of the hollow shaft 5 and is used to block and restrict the two through-line hinge leaves 3, so that a certain distance can be left between the two through-line hinge leaves 3 to avoid a large overlap between the two. A fixed cover 11 is fixed to an upper end and a lower end of the two through-line hinge leaves 3 to prevent the hollow shaft 5 from falling off, and is used to seal one end of the through-line hinge leaves 3. The two ends of the hollow shaft 5 are passed into the interior of the central axis hole 4 on the two through-line hinge leaves 3, and the two ends of the hollow shaft 5 are passed into the inner port position of the through-line hole 6 on the inner wall of the central axis hole 4. The solid load-bearing shaft 9 penetrates into the interior of the load-bearing central axis hole 8 on the two load-bearing door leaf leaves 7. A movable washer B13 is passed through the center position of the surface of the solid load-bearing shaft 9 to avoid a large overlap between the two and reduce the friction on the outer surface of the solid load-bearing shaft 9.

[0021] One end of the two load-bearing door leaf pieces 7 is connected with a hinge cover 14 that seals the solid load-bearing shaft 9 in the load-bearing central axis hole 8, and a wiring harness body 12 connected to an external electronic lock and a battery is passed into the hollow shaft 5. Both ends of the wiring harness body 12 pass through both ends of the hollow shaft 5, and after passing through the hollow shaft 5, the wiring harness body 12 passes through the wire hole 6 to the outside end of the central axis hole 4 on the two wire-passing hinge leaves 3.

[0022] Specifically, when in use, the two line-passing hinge sheets 3 in the line-passing hinge 1 have a hollow central axis hole 4, and a lateral through-line hole 6 is installed in the central axis hole 4 of one of the line-passing hinge sheets 3 as a fixed axis. The central axis hole 4 is connected to one of the line-passing hinge sheets 3 by welding, and a fixing cover 11 is buckled on the central axis hole 4. Another line-passing hinge sheet 3 that also has a lateral through-line hole 6 is installed on the upper end of the central axis hole 4, and the two ends of the hollow axis 5 are passed into the central axis holes on the two line-passing hinge sheets 3. 4, thus forming a wire hinge 1 with a rotation function, the wire harness body 12 passes through the wire hole 6 from the lower end to the upper end through a wire hinge leaf piece 3, and passes through the inside of the hollow shaft 5, and passes through the wire hole 6 from the side of the central axis hole 4 on the other wire hinge leaf piece 3 and then extends out, completing the threading action of the wire harness body 12, so that one side of the wire harness body 12 is on the side of the wire hinge leaf piece 3 on the door frame, and one end is on the side of the wire hinge leaf piece 3 on the door leaf, which has the protection function of the wire harness body 12.
