[0001] The utility model relates to the field of shrapnel antennas, in particular to a BLE shrapnel antenna for a door lock capable of multi-directional radiation. Background Art

[0002] A BLE shrapnel antenna is a type of antenna used for Bluetooth low energy devices. It is usually made of metal shrapnel. The length and shape of the antenna can be adjusted by bending or stretching, making it easier to install inside the door lock. The BLE shrapnel antenna can radiate signals in multiple directions, thereby improving the communication stability and reliability between the door lock and other devices.

[0003] Currently, BLE shrapnel antennas are usually installed by gluing or welding.

[0022] The following is combined with Figure 1 —5 provide further details of this application,

[0023] The embodiment of the present application discloses a BLE shrapnel antenna for a door lock capable of radiating in multiple directions. Figure 1A BLE shrapnel antenna for a door lock capable of multi-directional radiation includes a lock housing 1, a hollow plate 2 fixedly mounted on the left side of the interior of the lock housing 1, an antenna body 3 disposed within the hollow plate 2, a front and rear limiting component 4 disposed within the hollow plate 2, and upper and lower limiting components 5 disposed on the surface of the front and rear limiting component 4;

[0024] Reference Figure 2 - Figure 4 The front and rear limiting components 4 include two elastic telescopic rods 411 fixedly installed on the front and rear sides of the left inner wall of the hollow plate 2, the end of the elastic telescopic rod 411 away from the middle of the hollow plate 2 is fixedly connected to a connecting block 412, the right end of the connecting block 412 is rotatably connected to a push rod 413, and the other end of the push rod 413 away from the connecting block 412 is rotatably connected to a driven block 414, and the right end of the connecting block 412 is fixedly installed with a connecting rod 421, and an inner groove 422 is provided inside the right side of the connecting rod 421, and a rotating rod 423 is rotatably connected inside the inner groove 422, and a pressure spring 424 is fixedly installed on the surface of the rotating rod 423, and a fixed rod 425 is fixedly installed inside the front and rear ends of the hollow plate 2, a hollow block 431 is fixedly installed inside the hollow plate 2, and a pressure spring 2 is fixedly installed on the end of the hollow block 431 close to the inner wall of the hollow plate 2 432, the other end of the pressure spring 2 432 is fixedly installed with a pressure block 433, the driven block 414 and the middle part of the left end face of the antenna body 3 are in adaptive contact, and the end of the pressure spring 1 424 away from the rotating rod 423 is fixedly installed on the inner wall of the inner groove 422, and the elastic force of the pressure spring 1 424 pushes the rotating rod 423, so that the side of the rotating rod 423 away from the pressure spring 1 424 can push the pressure block 433 to move toward the inside of the hollow block 431, and the side of the rotating rod 423 away from the connecting rod 421 is in adaptive contact with the end of the pressure block 433 away from the pressure spring 2 432, and the end of the fixed rod 425 away from the inner wall of the hollow plate 2 is in adaptive contact with the side of the rotating rod 423 away from the connecting rod 421. After the rotating rod 423 contacts the fixed rod 425, the pressure spring 1 424 will be stretched. At this time, the rotating rod 423 rotates and disengages from the pressure block 433.

[0025] Reference Figure 5The upper and lower limiting components 5 include two sliding rods 51 slidably connected to the left and right sides of the pressure block 433. The end of the sliding rod 51 close to the inside of the hollow block 431 is fixedly installed with a connecting plate 52. The inside of the pressure block 433 is fixedly installed with a vertical rod 53. The surface of the vertical rod 53 is provided with a pressure spring 3 54. The inside of the vertical rod 53 is slidably connected with a pressing plate 55. The end of the sliding rod 51 away from the inside of the pressure block 433 is adapted to contact with the side wall of the antenna body 3. The end of the pressure block 433 away from the pressure spring 2 432 is adapted to contact with the side wall of the antenna body 3. The front and rear pressure blocks 433 can limit the front and rear sides of the antenna body 3. The top of the connecting plate 52 and the bottom of the pressing plate 55 are aligned. Adaptive contact, when the sliding rod 51 pushes the connecting plate 52 to move toward the inside of the pressure block 433, the connecting plate 52 will be separated from the bottom end of the pressing plate 55, and the top of the pressure spring three 54 is fixedly installed on the top of the inside of the pressure block 433, and the bottom end of the pressure spring three 54 is fixedly installed on the top of the pressing plate 55. The bottom end of the pressing plate 55 is fixedly installed with a friction block, and the bottom end of the pressing plate 55 and the top of the antenna body 3 are in adaptive contact. When the connecting plate 52 is separated from the bottom end of the pressing plate 55, the pressing plate 55 will move downward under the action of the rebound force of the pressure spring three 54 until the pressing plate 55 is pressed on the top of the antenna body 3 through the friction block, thereby stably limiting the top of the antenna body 3.

[0026] Working principle: When the operator needs to install the antenna body 3, he first puts the antenna body 3 into the interior of the hollow plate 2 and pushes it to the left. At this time, the antenna body 3 will push the driven block 414, and the driven block 414 will push the push rod 413. Then the push rod 413 will push the connecting block 412 and stretch the elastic telescopic rod 411. When the connecting block 412 is pushed by the push rod 413 toward the inner wall of the hollow plate 2, the connecting block 412 will drive the fixedly connected connecting rod 421 to move accordingly, and the connecting rod 421 will drive the rotating rod 423 to move accordingly. When the side of the rotating rod 423 close to the inner wall of the hollow plate 2 contacts the pressure block 433, the pressure spring 1 424 fixedly connected to the side of the rotating rod 423 away from the pressure block 433 is engaged. At this time, the pressure spring 1 424 Under the action of the elastic force, the rotating rod 423 cannot rotate. At this time, the rotating rod 423 pushes the pressure block 433 to move inside the hollow block 431. Then, the connecting rod 421 continues to drive the rotating rod 423 to move. When the rotating rod 423 contacts the fixed rod 425, the fixed rod 425 pushes the rotating rod 423. At this time, the rotating rod 423 stretches the pressure spring 1 424 and rotates. After the rotation, the rotating rod 423 gradually separates from the pressure block 433. When the rotating rod 423 is completely separated from the pressure block 433, the pressure block 433 moves toward the outside of the hollow block 431 under the action of the rebound force of the pressure spring 2 432 until the pressure block 433 limits the side wall of the antenna body 3. At this time, the front and rear ends of the antenna body 3 are limited by the front and rear pressure blocks 433.

[0027] When the pressure block 433 contacts the side wall of the antenna body 3, the sliding rod 51 will move toward the inside of the pressure block 433 under the reaction force of the antenna body 3. At this time, the sliding rod 51 will drive the connecting plate 52 to move accordingly until the connecting plate 52 is separated from the bottom end of the pressing plate 55. At this time, the bottom end of the pressing plate 55 is no longer subjected to the upward force, so the pressing plate 55 will move downward under the action of the rebound force of the pressure spring three 54. At this time, the pressing plate 55 moves downward and abuts against the top wall of the antenna body 3, and a friction block is fixed to the bottom end of the pressing plate 55. At this time, the pressing plate 55 stably limits the antenna body 3 through the friction block. At this time, the front and rear sides and the top of the antenna body 3 are all stably limited. Then, the antenna body 3 and the chip inside the lock shell 1 can be electrically connected.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
