DETAILED DESCRIPTION
[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0028] like Figure 1 As shown, a foldable antenna structure of an electronic device includes a fixing base 1, the inner side of the fixing base 1 is rotatably connected to a rotating mechanism 2, the upper side of the rotating mechanism 2 is fixedly connected to a storage tube 3, the inner side of the storage tube 3 is sequentially sleeved with a plurality of extension mechanisms 4, the inner side of the innermost extension mechanism 4 is movably sleeved with an end rod mechanism 5, and the upper side of the end rod mechanism 5 is fixedly connected to a sealing plate 6.
[0029] It should be noted that the fixing base 1 is used to connect with the electronic device, and the sealing plate 6 is used to seal the upper end of the entire antenna structure to prevent the end rod mechanism 5 and the extension mechanism 4 from completely entering the inner side of the storage tube 3, making it difficult to take them out.
[0030] like Figure 3As shown, the rotating mechanism 2 includes a first rotating seat 21, the outer wall of the first rotating seat 21 is rotatably connected to the inner side of the fixed seat 1 near the bottom, the inner cavity side of the fixed seat 1 is fixedly connected to the limiting ring 22, the inner surface of the limiting ring 22 is wavy, and the outer wall of the first rotating seat 21 near the bottom is movably sleeved with a plurality of annularly distributed blocks 23, the sides of the plurality of blocks 23 away from the limiting ring 22 are fixedly connected to the limiting rod 24, and the sides of the plurality of blocks 23 away from the limiting rod 24 are overlapped on the inner side of the limiting ring 22, and the upper and lower sides of the inner cavity of the bottom wall of the first rotating seat 21 are fixedly connected with limiting plates 26, the outer wall of the limiting rod 24 is movably sleeved in the jacking hole opened on the outer wall of the limiting plate 26, and the outer walls of the plurality of limiting rods 24 are movably sleeved with first springs 25, and the first springs 25 are located on the outside of the limiting plate 26.
[0031] It should be noted that, by rotating the first rotating seat 21, the block 23 revolves, and the inner wall of the limiting ring 22 pushes the block 23 to move toward the side closer to each other. When the block 23 moves to the recessed part of the inner surface of the limiting ring 22, the first spring 25 pushes the block 23 to move outward. Relying on the elastic force of the first spring 25, the rotation of the first rotating seat 21 is controlled to prevent it from rotating without restriction.
[0032] like Figure 3 , Figure 4 As shown, the second limiting ring 28 is fixedly connected to the inner left and right surfaces of the first rotating seat 21, the first rotating shaft 27 is fixedly connected to the middle of the inner left and right surfaces of the first rotating seat 21, and the first rotating shaft 27 is located on the inner side of the second limiting ring 28, the second rotating seat 211 is fixedly connected to the middle of the outer wall of the first rotating shaft 27, the third limiting ring 29 is movably sleeved on the outer wall of the first rotating shaft 27 near the left and right sides, the second spring 210 is movably sleeved on the outer wall of the first rotating shaft 27 near the left and right sides, and the second spring 210 is located on the side of the third limiting ring 29 close to each other, the side of the second limiting ring 28 close to each other is wavy, and the side of the third limiting ring 29 away from each other is wavy, and the side of the second limiting ring 28 close to each other is meshed and connected with the side of the third limiting ring 29 away from each other.
[0033] It should be noted that, by rotating the second rotating seat 211, the third limit ring 29 is driven to rotate, and the second limit ring 28 pushes the third limit ring 29 to move toward the side close to each other. When the second spring 210 pushes the third limit ring 29 to be close to the second limit ring 28, relying on the elastic force of the second spring 210, the rotation of the third limit ring 29 is controlled to prevent it from rotating without restriction.
[0034] like Figure 4 As shown, the outer wall of the first rotating shaft 27 is provided with a plurality of annular limiting grooves, and the inner protrusions of the third limiting ring 29 are slidably connected in the limiting grooves.
[0035] It should be noted that the limiting groove is used to fix the third limiting ring 29 so that the third limiting ring 29 can only move laterally to prevent the third limiting ring 29 from not rotating with the first rotating shaft 27 when the first rotating shaft 27 rotates.
[0036] like Figure 5 , Figure 6 As shown, several extension mechanisms 4 include a first extension sleeve rod 41, and several first extension sleeve rods 41 are sequentially connected to each other. The outer wall of the first extension sleeve rod 41 is provided with four annularly distributed first receiving grooves 42, and the inner sides of the four first receiving grooves 42 near the bottom are rotatably connected to the second rotating shafts 43, and the middle parts of the outer walls of the four second rotating shafts 43 are fixedly connected to the first support rods 44.
[0037] It should be noted that the first extension sleeve 41 is used to extend the length of the entire antenna structure so that it can better receive signals. The first support rod 44 is used to enhance the signal receiving capability. The first support rod 44 can be rotated to be stored in the inner side of the first storage slot 42.
[0038] like Figure 5 , Figure 6 As shown, third springs 45 are movably sleeved on positions of the outer walls of the four second rotating shafts 43 near both ends, and the third springs 45 are located on both sides of the first support rod 44 .
[0039] It should be noted that the third spring 45 is a torsion spring, and when the first extension sleeve 41 is pulled out from the outer storage tube 3 or the inner side of other first extension sleeves 41 , the first support rod 44 pops out automatically.
[0040] like Figure 7 As shown, the end rod mechanism 5 includes a second extension sleeve rod 51, the outer wall of the second extension sleeve rod 51 is movably sleeved on the inner side of the innermost first extension sleeve rod 41, and the outer wall of the second extension sleeve rod 51 is provided with six annularly distributed second receiving grooves 52, and the inner sides of the six second receiving grooves 52 near the bottom are all rotatably connected with second support rods 53.
[0041] It should be noted that the second receiving groove 52 is used to receive the second support rod 53, and the second support rod 53 is used to enhance the signal receiving capability.
[0042] like Figure 7 As shown, the inner side of the second extension sleeve 51 is threadedly connected with a pull rod 55 , the lower end of the pull rod 55 is fixedly connected with a baffle 54 , and the lower surface of the sealing plate 6 is fixedly connected to the upper end of the pull rod 55 .
[0043] It should be noted that when the second support rod 53 is in a horizontal state, the ends of the second support rod 53 that are close to each other are located on the upper side of the baffle 54, so that the second support rod 53 is fixed horizontally. By rotating the pull rod 55, the height of the baffle 54 can be driven. When the baffle 54 is at the lowermost side, the second support rod 53 can be re-transferred into the inner side of the second receiving groove 52. Since the diameter of the innermost second extension sleeve 51 is thinner than that of the first extension sleeve 41, a torsion spring drive is no longer used.
[0044] The working principle of the utility model is as follows: first, the first rotating seat 21 is rotated to make the block 23 revolve, and the inner wall of the limiting ring 22 pushes the block 23 to move to the side close to each other. When the block 23 moves to the recessed part of the inner surface of the limiting ring 22, the first spring 25 pushes the block 23 to move outward. Relying on the elastic force of the first spring 25, the rotation of the first rotating seat 21 is controlled to prevent it from rotating without restriction. The second rotating seat 211 is rotated to drive the third limiting ring 29 to rotate. The second limiting ring 28 pushes the third limiting ring 29 to move to the side close to each other. When the second spring 210 pushes the third limiting ring 29 to be close to the second limiting ring 28, relying on the elastic force of the second spring 210, the rotation of the third limiting ring 29 is controlled to prevent it from rotating without restriction. By rotating the first rotating seat 21, the upper structure is rotated. By rotating the second rotating seat 211, the upper structure is offset, so that the entire antenna structure can be adjusted when facing signals in all directions, so that the signal reception is better. The first extension sleeve 41 is used to extend the length of the entire antenna structure so that it can better receive signals. The first support rod 44 is used to enhance the signal receiving capability. The first support rod 44 can be rotated to store it in the inner side of the first receiving groove 42. The second receiving groove 52 is used to store the second support rod 53. The second support rod 53 is used to enhance the signal receiving capability. When the second support rod 53 is in a horizontal state, the ends of the second support rod 53 that are close to each other are located on the upper side of the baffle 54, so that the second support rod 53 is fixed horizontally. The pull rod 55 can be rotated to drive the height of the baffle 54. When the baffle 54 is at the lowest side, the second support rod 53 can be transferred back to the inner side of the second receiving groove 52. The first support rod 44 is stored through the first receiving groove 42, and the second support rod 53 is stored in the second receiving groove 52, so that the extension mechanism 4 and the end rod mechanism 5 can be completely placed in the inner side of the storage tube 3, which greatly reduces the volume of the entire antenna structure and facilitates transportation.
[0045] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
