[0026] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Figure 1 This is a schematic diagram of the overall structure of a flip cover structure proposed in an embodiment of this application; Figure 2 for Figure 1 Structural breakdown diagram of the Chinese embodiment Figure 1 ; Figure 3 for Figure 1 Structural breakdown diagram of the Chinese embodiment Figure 2 ; Figure 4 This is a schematic diagram of the worm gear structure in an embodiment of this application.

[0028] refer to Figures 1-4 It should be understood that Figure 2 and Figure 3 The connections between the various components should be like Figure 1 As compact as in the middle, this is only for illustrative purposes and will Figure 2 and Figure 3 The components are shown disassembled for easier understanding. This application provides a flip-top structure, which may include a housing 1, a worm gear 2, a drive unit 3, a rotating shaft 4, a worm wheel 5, and a rocker arm 6. The housing 1 has a through groove 11. The worm gear 2 is disposed inside the housing 1 and has a degree of freedom to rotate about a first direction, which is the same as the axial direction of the worm gear 2. The drive unit 3 is fixed inside the housing 1 and connected to one end of the worm gear 2, and the drive unit 3 provides rotational driving force to the worm gear 2. The rotating shaft 4 is disposed outside the housing 1 and rotatably connected to the housing 1. The axial direction of the rotating shaft 4 is the same as a second direction, which is perpendicular to the first direction. The worm wheel 5 passes through the through groove 11 and is sleeved on the outer periphery of the rotating shaft 4, wherein the worm wheel 5 meshes with the worm gear 2. The rocker arm 6 is disposed outside the housing 1 and connected to the rotating shaft 4. The end of the rocker arm 6 away from the rotating shaft 4 is connected to the flip-top.

[0029] The flip-top structure proposed in this application embodiment allows the housing 1 to be installed at the launch tube during use. The swing rod 6 is connected to the flip-top, and the worm gear 2 is driven to rotate by the drive unit 3. The worm gear 2 drives the worm wheel 5 and the rotating shaft 4 to rotate. The rotating shaft 4 further drives the flip-top to flip, thereby opening or closing the launch tube. During the process, the worm gear 2 drives the worm wheel 5 to rotate to drive the flip-top to flip, achieving self-locking, preventing accidental operation of the flip-top, and greatly improving safety and stability.

[0030] Specifically, such as Figure 1 As shown, the first direction is the X direction, the second direction is the Y direction, and the shell 1 can be a rectangular structure. The shell 1 has a length, width and height. The first direction can be the length direction of the shell 1, the second direction can be the width direction of the shell 1, and the height direction of the shell 1 can be the same as the gravity direction. The shell 1 can be made of high-strength aluminum alloy to ensure the strength and corrosion resistance of the shell 1 and improve the environmental adaptability of the shell 1.

[0031] It should be noted that there are many traditional solutions for how the housing 1 is installed at the launch tube so that the swing arm 6 is connected to the flip cover, thereby driving the flip cover to open or close the launch tube, which will not be elaborated here.

[0032] In the exemplary embodiment, both the worm gear 5 and the worm 2 are made of high-performance stainless steel, which can significantly improve the service life and corrosion resistance of the worm gear 5 and the worm 2, so that the flip structure can be used in harsher environments.

[0033] In an exemplary embodiment, the drive unit 3 is a hollow cup high-torque motor, and the output shaft of the drive unit 3 is connected to the worm gear 2 and its axial direction coincides with that of the worm gear 2.

[0034] Specifically, the drive unit 3 is fixed inside the housing 1, one end of the worm gear 2 is fixed to the output shaft of the drive unit 3, and the worm gear 2 is coaxial with the output shaft of the drive unit 3, so that when the output shaft of the drive unit 3 rotates, it can drive the worm gear 2 to rotate synchronously.

[0035] Furthermore, the worm 2 can be hollow, so that the worm 2 can be sleeved on the output shaft of the drive unit 3 to facilitate the connection of the worm 2.

[0036] It should be understood that a speed reducer or other speed control mechanism can also be connected between the worm gear 2 and the drive unit 3 to make the rotation speed of the drive unit 3 adapt to the flipping of the cover. There are many traditional solutions for speed reducers or other speed control mechanisms, which will not be elaborated here.

[0037] Among them, the hollow cup high torque motor drive provides powerful rotational torque, while occupying little space, which greatly reduces the overall space occupied by the flip cover structure and makes it easier to lay the shell 1 on the launch tube.

[0038] refer to Figure 2 In an exemplary embodiment, the housing 1 has a recess 12, and the recess 12 has a first sidewall and a second sidewall disposed opposite to each other in a second direction; wherein, the rotating shaft 4 is rotatably connected between the first sidewall and the second sidewall; in the second direction, a through groove 11 is disposed at the center position of the rotating shaft 4.

[0039] Specifically, such as Figure 2 As shown, the recessed portion 12 has a first sidewall and a second sidewall that are arranged opposite to each other in a second direction. The two ends of the rotating shaft 4 are rotatably connected to the first sidewall and the second sidewall respectively. In this way, the first sidewall and the second sidewall support the two ends of the rotating shaft 4, making the rotation process of the rotating shaft 4 more stable.

[0040] Furthermore, in the second direction, the through groove 11 is located at the center of the rotating shaft 4. That is, in the axial direction of the rotating shaft 4, the worm gear 5 is located at the center of the rotating shaft 4, so that the rotating shaft 4 is subjected to more uniform force and the rotation process is more stable.

[0041] refer to Figure 2 and Figure 3 In a preferred embodiment, the worm wheel 5 is fan-shaped, and all the meshing teeth of the worm wheel 5 are located inside the housing 1. Thus, only part of the structure of the worm wheel 5 at the connection with the rotating shaft 4 passes through the through groove 11. When the worm 2 drives the worm wheel 5 to rotate, the fan-shaped worm wheel 5 rotates inside the housing 1, thereby driving the rotating shaft 4 and the flip cover to rotate. In this way, the fan-shaped structure of the worm wheel 5, instead of a complete circular structure, can complete the transmission function and greatly reduce the space occupied by the worm wheel 5, thereby making the flip cover structure more compact.

[0042] It should be noted that the recess 12 can be provided on one side of the housing 1, or it can be provided at the corner of adjacent sides of the housing 1. In the embodiment of this application, it is used as follows: Figure 2 Taking the state shown as an example, the recessed part 12 is provided at the upper right corner of the housing 1 so that the swing rod 6 can be connected to the flip cover. At the same time, the side wall of the recessed part 12 can limit the swing range of the swing rod 6 to prevent the flip cover from being opened or closed too much. Of course, if it is necessary to change the swing range of the swing rod 6, the shape of the recessed part 12 can be changed, which will not be elaborated here.

[0043] refer to Figure 1 and Figure 2 In an exemplary embodiment, the flip structure may further include a cover 7, which is fixed to the outside of the housing 1 and connected to the housing 1. The cover 7 is located at the through groove 11 to seal the through groove 11. The rotating shaft 4 passes through the connection area between the cover 7 and the housing 1. The cover 7 divides the recess 12 into two compartments arranged in the second direction. The swing rod 6 passes through the two compartments and is connected to the rotating shaft 4.

[0044] Specifically, by setting the cover 7, the shell 1 can be sealed, thereby greatly improving the safety of the internal structure of the shell 1, increasing the service life of the flip structure and its adaptability to harsh environments.

[0045] The rotating shaft 4 passes through the connection area between the cover 7 and the housing 1. It can be understood that the through groove 11 and the area where the cover 7 is close to each other are provided with semi-circular through holes corresponding to the rotating shaft 4, so that the rotating shaft 4 can pass through the connection area between the cover 7 and the housing 1.

[0046] In addition, after the cover 7 seals the through groove 11, the worm gear 5 is entirely located within the sealed area enclosed by the cover 7 and the housing 1.

[0047] Furthermore, the cover 7 divides the recess 12 into two compartments arranged in the second direction. The swing arm 6 passes through the two compartments and connects to the rotating shaft 4. That is, there are two connection areas between the swing arm 6 and the rotating shaft 4, which makes the rotation process of the swing arm 6 more stable. For example, Figure 1 and Figure 2 As shown, the swing arm 6 can be U-shaped, with each end of the swing arm 6 inserted into a compartment to be fixed to the rotating shaft 4. In this way, during the rotation of the swing arm 6, the middle area of ​​the swing arm 6 can avoid the cover 7, making the flip cover mechanism structure more compact.

[0048] refer to Figures 2-4 In an exemplary embodiment, the housing 1 also has a through hole 13 that coincides with the worm gear 2 in the axial direction; the flip structure may also include a connecting shaft 81, which is rotatably connected to the housing 1 and has the same axial direction as the worm gear 2. One end of the connecting shaft 81 is connected to the end of the worm gear 2 away from the drive part 3, and the other end of the connecting shaft 81 is inserted into the through hole 13; wherein, the part of the connecting shaft 81 away from the worm gear 2 is a prismatic structure.

[0049] Specifically, rotating the connecting shaft 81 will drive the worm gear 2 to rotate, which in turn drives the rocker arm 6 to rotate. In this way, even if there is a power outage or other special circumstances and the drive unit 3 cannot work normally, the connecting shaft 81 can be manually rotated to drive the worm gear 2 to rotate, making it more convenient to use.

[0050] Furthermore, the part of the connecting shaft 81 away from the worm 2 is a prismatic structure. That is to say, the end of the connecting shaft 81 that is inserted into the through hole 13 is a prismatic structure. Thus, the connecting shaft 81 can be rotated by inserting the corresponding sleeve tool, which is convenient and quick.

[0051] In this embodiment of the application, the prism-shaped structure can be a hexagonal prism, and the corresponding socket tool can be a hexagonal socket wrench.

[0052] refer to Figure 1 and Figure 2In an exemplary embodiment, the flip structure may further include a plug 82, which is disposed at the end of the through hole 13 away from the worm gear 2 to seal the through hole 13.

[0053] Specifically, when the worm gear 2 needs to be manually rotated, remove the plug 82, then rotate the connecting shaft 81. After rotation, insert the plug 82 into the through hole 13 to seal the through hole 13, thus ensuring the overall sealing of the flip structure.

[0054] In an optional embodiment, a control board can be installed inside the housing 1. A power interface is provided on the housing 1, and an angle calculation mechanism is arranged at the rotating shaft 4. The control board is electrically connected to the power interface and the angle calculation mechanism. The angle calculation mechanism may include a Hall sensor and a magnet, etc. The corresponding position is set so as to use the Hall effect to determine the position of the swing arm 6 to realize the specific angle calculation. The Hall effect is a mature application in angle calculation, and will not be elaborated here. In this way, when the control board receives the control command, it can control the drive unit 3 to rotate according to the real-time calculation of the angle calculation mechanism, so that the swing arm 6 swings to the preset angle, thereby realizing automatic control.

[0055] Additionally, it should be noted that the housing 1 is detachable and not a complete one-piece structure, in order to facilitate the maintenance of the internal structure of the housing 1. In order to meet the working requirements of harsh environments such as rain, heat and humidity, and salt spray, high-performance rubber and sealant can be used to seal the joints of the various parts of the housing 1 to ensure the sealing and reliability of the flip structure during long-term use.

[0056] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
