[0040] The embodiments of the present utility model are as follows Figures 1-11As shown, it relates to a foldable antenna for a remote controller, including a remote controller body 1 and an antenna body 2. A first accommodation groove 101 is provided at the top of the remote controller body 1, and a sliding channel 102 is provided at the bottom of the first accommodation groove 101; the antenna body 2 includes an antenna head 201 and an antenna trunk 202. The antenna trunk 202 is inserted into the sliding channel 102 and can slide directionally in the sliding channel 102. The antenna body 2 has two states. In the first state, the antenna head 201 is located in the first accommodation groove 101, and the antenna trunk 202 is retracted into the sliding channel 102. In the second state, the antenna trunk 202 is lifted upward so that it extends out of the sliding channel 102, and the antenna head 201 is synchronously lifted upward with the antenna trunk 202 to be separated from the first accommodation groove 101. Further, when using the present utility model, the user can pull the antenna head 201 to lift the antenna head 201 so that the antenna head 201 is separated from the first accommodation groove 101, and the antenna trunk 202 slides upward in the sliding channel 102 so that its top is higher than the top end of the sliding channel 102, thereby improving the transmission and reception of antenna signals. When it is necessary to store and carry the present utility model, only need to push down the antenna head 201 so that the antenna head 201 descends into the first accommodation groove 101. At this time, the antenna trunk 202 slides downward in the sliding channel 102 so that its top is lower than or equal to the top end of the sliding channel 102, thereby completing the storage of the antenna body 2. Further, the height of the antenna head 201 is equal to the depth of the first accommodation groove 101, and the first accommodation groove 101 communicates with the back of the remote controller body.

[0041] Referring to Figure 9 , in this embodiment, a guiding groove 103 communicating with the bottom of the first accommodation groove 101 is provided on one side of the remote controller body 1. The guiding groove 103 can facilitate the user to push and pull the antenna head 201. Further, the bottom of the guiding groove 103 is inclined, and the inclined direction is from bottom to top and inclined toward the operation panel of the remote controller body 1. Optionally, a plurality of guiding grooves 103 are provided, and there are two in this embodiment. When in use, the user places a finger in the guiding groove 103 and then slides along the guiding groove 103 to touch the bottom end of the antenna head 201, so as to facilitate lifting the antenna head 201. And the bottom of the guiding groove 103 is inclined, and the inclined direction is from bottom to top and inclined toward the operation panel of the remote controller body 1, so that the user's finger will naturally slide along the inclined surface to provide a better guiding and smooth experience of lifting the antenna head.

[0042] Referring to Figures 9-11, in this embodiment, a plurality of electrical connection sockets 104 are provided at the bottom of the first accommodation groove 101. Optionally, the electrical connection sockets 104 include a USB interface and a DSC interface. When the antenna body 2 is not lifted, the antenna head 201 shields the electrical connection sockets 104, which not only makes full use of the space but also makes the present utility model more beautiful.

[0043] Refer to Figures 1-11 , in this embodiment, the antenna body 2 is in a T shape. The antenna trunk 202 includes a columnar connection part 202.1 integrally formed with the bottom end of the antenna head 201 and a column body part 202.2 damping-hinged to the columnar connection part. Optionally, the integrally formed design of the antenna head 201 and the columnar connection part 202.1 enhances the integrity and stability of the structure, reducing the risk of antenna performance degradation caused by loosening or breaking of the connection part. The damping-hinged design allows the columnar connection part 202.1 and the column body part 202.2 to rotate flexibly within a certain range, so that the antenna head 201 can rotate relative to the antenna trunk 202 while maintaining a certain damping force to prevent the antenna head 201 from swinging randomly when not needed, thus ensuring the stability of the antenna during use. The antenna trunk can rotate within the sliding channel. The user can push the antenna head 201 to rotate horizontally. At this time, the antenna head 201 and the antenna trunk rotate synchronously. Due to the existence of the rotation-limiting and anti-disengagement component and the rotation limiting member (not shown in the figure), the rotation-limiting and anti-disengagement component and the rotation limiting member cooperate to limit the antenna head 201 to rotate only 90 degrees clockwise or 90 degrees counterclockwise. Further, since the columnar connection part 202.1 is integrally formed at the bottom end of the antenna head 201 and the column body part 202.2 is damping-hinged to the connection part, the antenna head 201 can swing up and down. When the degree of the up-and-down swing of the antenna head 201 is different and it rotates to different angles, the direction of the radiated electromagnetic wave field is different, and the electromagnetic wave field is strong in the direction pointed by the antenna. The user can adjust the degree of the up-and-down swing and the rotation angle of the antenna head 201 according to needs. The rotation direction of the antenna head 201 is the length direction of the antenna head 201.

[0044] In this embodiment, an annular assembly groove is provided on the outer peripheral side of the column body part 202.2, and a rubber ring 202.22 is provided on the annular assembly groove. Further, the existence of the rubber ring 202.22 causes the column body part 202.2 to rub against the inner wall of the sliding channel 102 in the sliding channel 102. When the pushing or pulling force applied by the user is greater than this frictional force, the column body part 202.2 slides in the sliding channel 102. When the user does not apply a pushing or pulling force, the column body part 202.2 is stationary in the sliding channel 102, thereby preventing the antenna body 2 from being accidentally lifted or retracted and increasing the stability of the antenna body 2 during use.

[0045] Refer to Figures 1-11 In this embodiment, a first through hole 202.11 penetrating through the top and bottom thereof is provided on the columnar connecting portion 202.1, a second through hole 202.23 penetrating through the top and bottom thereof is provided on the column body portion 202.2, a communication component 3 and a wire 4 electrically connected to the antenna are arranged inside the antenna body 2, and a third through hole 201.21 penetrating through the top and bottom thereof is provided on the lower shell 201.2. The first through hole 202.11, the second through hole 202.23, and the third through hole 201.21 are communicated in sequence, and the wire 4 is arranged in the first through hole 202.11, the second through hole 202.23, and the third through hole 201.21. Specifically, by providing the first through hole 202.11, the second through hole 202.23, and the third through hole 201.21, the wire 4 can pass through and be connected to the electronic components inside the remote control body 1, and it can avoid the wire 4 being exposed outside the antenna body 2 or occupying extra space, making the overall structure more compact. Hiding the wire 4 in the through hole can reduce the possibility of the user directly contacting the wire 4.

[0046] In this embodiment, the antenna head 201 includes an upper shell 201.1 and a lower shell 201.2 that are detachably connected. A second accommodation groove 201.22 is provided at the top of the lower shell 201.2, and a first antenna fixing member is arranged in the second accommodation groove 201.22. A third accommodation groove 201.12 is provided at the bottom of the upper shell 201.1, and a second antenna fixing member adapted to the first antenna fixing member is arranged in the third accommodation groove 201.12. Further, the first antenna fixing member includes a plurality of first support plates 201.24 arranged in the first accommodation groove 101, and a first arc-shaped groove 201.25 is provided at the top of the first support plate 201.24. The second antenna fixing member includes a plurality of second support plates 201.14, and a second arc-shaped groove 201.15 is provided at the bottom of the second support plate 201.14. In this embodiment, the communication component 3 is cylindrical. During assembly, the lower half end of the communication component 3 is arranged on the first arc-shaped groove 201.25 on the first support plate 201.24, and the upper shell 201.1 and the lower shell 201.2 are connected. At this time, the upper half end of the communication component 3 is arranged in the second arc-shaped groove 201.15 on the second support plate 201.14 to abut against the communication component 3 and prevent the communication component 3 from shifting. Optionally, the first support plate 201.24 and the second support plate 201.14 are made of an elastic material, preferably rubber.

[0047] Refer to Figures 1-2 、 Figures 6-8, in this embodiment, on opposite side walls of the lower shell 201.2, there are provided assembly walls 201.26 extending towards the upper shell 201.1. On the outer side of the assembly walls 201.26, there are provided clamping grooves 201.27, and on the inner wall of the upper shell 201.1, there are provided clamping blocks 201.16 adapted to the clamping grooves 201.27. Specifically, through the cooperation of the clamping grooves 201.27 and the clamping blocks 201.16, a tight and stable connection can be formed between the upper shell 201.1 and the lower shell 201.2, and it is not easy to loosen or separate due to external forces. When the device is subjected to external impacts or vibrations, this clamping structure can effectively disperse and absorb the impact force to protect the internal components from damage. Further, the clamping structure makes the assembly process of the upper shell 201.1 and the lower shell 201.2 more simple and fast, and the assembly can be completed without additional fixing parts or tools. When it is necessary to repair or replace the internal components, the upper shell 201.1 can be easily detached from the lower shell 201.2, facilitating subsequent maintenance or replacement of the components inside the upper shell 201.1 and the lower shell 201.2.

[0048] In this embodiment, at one end of the columnar portion 202.2 away from the columnar connection portion 202.1, there is provided a rotation-limiting anti-disengagement component 202.3. The rotation-limiting anti-disengagement component 202.3 can prevent the columnar portion 202.2 from disengaging from the sliding channel 102 and cooperate with a rotation-limiting member (not shown in the figure) provided inside the remote control body to limit the rotation angle of the antenna body. When the antenna body rotates 90 degrees clockwise or 90 degrees counterclockwise, the rotation-limiting anti-disengagement component will contact the rotation-limiting member, and the rotation-limiting member limits the antenna body to only rotate 90 degrees clockwise or 90 degrees counterclockwise. Optionally, the rotation-limiting anti-disengagement component 202.3 is an anti-disengagement block integrally formed with the columnar portion 202.2.
