Description

Technical Field

[0001] This case relates to a dynamic Christmas tree, and more particularly to a dynamic Christmas tree with controllable branch swinging and / or lighting effects. Background Technology

[0002] Internationally, it's a festive tradition to display Christmas trees and decorate them. Currently, Christmas tree decorations simply involve hanging ornaments from the branches or wrapping strings of lights around them. However, these decorations create a static visual effect; currently, Christmas trees cannot achieve dynamic visual effects. Some people place the base of the Christmas tree on a rotating platform, but this rotation effect is monotonous, and since Christmas trees are over one meter tall, rotating them from the base could easily cause them to tip over. Summary of the Invention

[0003] In view of this, a dynamic Christmas tree is provided. The dynamic Christmas tree includes a main pole, a first support pole, and a turntable assembly. The main pole includes a top and a bottom. An active layer is provided between the top and the bottom. The first support pole is connected to the main pole and located in the active layer. The turntable assembly has a first actuating part, which is fixed to the main pole and extends toward the first support pole. When actuated, the turntable assembly drives the first actuating part to move around the main pole to intermittently push the first support pole to swing relative to the main pole.

[0004] In some embodiments, the dynamic Christmas tree further includes a second support rod and a connecting wire. The second support rod is connected to the main rod and located in the driven layer between the active layer and the bottom. One end of the connecting wire is connected to the second support rod, and the other end is connected to either the first support rod or the turntable assembly, with the connecting wire located outside the turntable assembly.

[0015] In some embodiments, the rotary connection assembly includes a base, a rotor, and a motor. The base is connected to the top of the main rod. One end of the rotor is connected to the base, and the other end is connected to the top rod. The motor is connected to the base and is used to drive the rotor to rotate according to a drive signal.

[0016] In some embodiments, the rotor includes a connecting sleeve that is fitted onto the motor shaft, causing the shaft to drive the rotor to rotate; wherein the connecting sleeve further includes a guide opening for guiding the rotor into the connecting sleeve.

[0017] In some embodiments, the rotary connection assembly further includes a bearing and a connecting bracket. The bearing is pivotally mounted on the motor and has two first electrodes. Two second electrodes of the base surround the bearing and are electrically connected to the two first electrodes respectively.

The electrical connection terminal is connected to the electrical connection socket, and the electrical connection socket is electrically connected to the two first electrodes to drive the rotor and the connecting bracket to rotate synchronously.

[0018] In some embodiments, the dynamic Christmas tree further includes a first light-emitting unit and a second light-emitting unit. The first light-emitting unit, the second light-emitting unit, the motor, the drive component, and the controller are respectively connected by two wires to form a control loop. The first light-emitting unit and the second light-emitting unit each have a light-driving chip, which is used to selectively drive the first light-emitting unit and the second light-emitting unit according to the drive signal.

[0019] In some embodiments, the main pole is assembled from a first pole body and a second pole body, each having an active layer and a driven layer. The dynamic Christmas tree further includes a rotating connection assembly. One end of the rotating connection assembly is connected to the bottom of the first pole body, and the other end is connected to the top of the second pole body.

The dynamic Christmas tree also includes a tilt sensor, which sends a warning signal when the main pole is detected to be tilting. The controller stops sending drive signals based on the warning signal.

[0023] In summary, in some embodiments of the dynamic Christmas tree, the rotation of the turntable assembly is controlled to directly or indirectly drive the first and second support rods to swing. Accordingly, the swing sequence of the first and second support rods can be further controlled based on the travel distance or rotation speed of the turntable assembly. The swinging of the support rods, in conjunction with the lighting, simulates the dynamic effect of tree branches being blown by the wind, thus satisfying the user's demand for dynamic effects such as the swinging and lighting of the Christmas tree.

Detailed Implementation

[0042] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the present invention, but it is not intended to limit the scope of protection of the appended claims.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown. The dynamic Christmas tree 100 includes a main pole 102, a first support pole 104, and a turntable assembly 106. The main pole 102 includes a top 108 and a bottom 110. An active layer 112 is provided between the top 108 and the bottom 110. The first support pole 104 is connected to the main pole 102 and located in the active layer 112. The turntable assembly 106 has a first actuation part 114, which is fixed around the main pole 102 and extends toward the first support pole 104. When actuated, the turntable assembly 106 drives the first actuation part 114 to move around the main pole 102 to intermittently push the first support pole 104 to swing relative to the main pole 102.

[0044] The main pole 102 can refer to the trunk of the dynamic Christmas tree 100. The main pole 102 can be a hollow pole, and the dynamic Christmas tree 100 can be connected to the turntable assembly 106 via two wires inside the main pole 102 to provide power or send signals to the turntable assembly 106.

[0045] The first support rod 104 can refer to a branch of the dynamic Christmas tree 100. The active layer 112 can be determined by the position of the first support rod 104 on the main rod 102. For example, the active layer 112 can be provided with at least one first support rod 104. At least one first support rod 104 can be arranged in a ring around the surface of the main rod 102. For example, multiple first support rods 104 can be arranged at the same height around the main rod 102, so that the turntable assembly 106 can actuate one or more first support rods 104 at the same height position.

[0046] The turntable assembly 106 can be fixed to the main rod 102 with the main rod 102 as the center, so that the turntable assembly 106 can rotate around the main rod 102 as the axis. For example... Figure 4 and Figure 5 As shown, the first actuating part 114 may be a protruding structure extending from the turntable assembly 106 toward the first support rod 104. This can mean that the turntable assembly 106 is disposed between the first support rod 104 and the bottom 110 (i.e., the turntable assembly 106 is located below the first support rod 104), and the first actuating part 114 may be a protruding structure extending from the turntable assembly 106 toward the first support rod 104. Figure 2 The center Y-axis extends to the first support rod 104. Alternatively, the turntable assembly 106 can be positioned between the first support rod 104 and the top 108 (i.e., the turntable assembly 106 is located above the first support rod 104), and the first actuating part 114 can be oriented towards... Figure 2 The center-negative Y-axis extends to the first support rod 104. In some embodiments, the turntable assembly 106 can be cut open from the center (which may be the central shaft hole 125 described later) to form a symmetrical and separable assembly kit (such as...). Figure 5 The turntable assembly 106 is cut open along the 5-5 direction. The turntable assembly 106 can be disassembled and aligned with the main rod 102, then reassembled to be fixed to the main rod 102 (it can be fixed using screws or snap-fit ​​mechanisms, such as...). Figure 5 The turntable assemblies 106 on both sides of the mid-section line are secured by screws passing through them in the Z-axis direction, or by snap-fit ​​structures on both sides of the mid-section line. Thus, the turntable assemblies 106 can be applied to Christmas trees of different sizes, and users can manually install them onto the Christmas tree to activate it.

[0047] For example Figure 4 As shown, the first actuating part 114 includes a top end 114a and a bottom end 114b, with the top end 114a capable of pushing against the first support rod 104. The first support rod 104 can be located between the top end 114a and the bottom end 114b. Alternatively, the top end 114a can be at the same height as the first support rod 104 (the top end 114a does not extend beyond the first support rod 104). Accordingly, when the turntable assembly 106 rotates, during the process of the first actuating part 114 circling relative to the main rod 102, the first actuating part 114 can intermittently push against the first support rod 104 to swing vertically relative to the main rod 102 (this could mean the first support rod 104 swings towards the top 108 or swings towards the bottom 110 in the Y-axis direction). It should be noted that the intermittent pushing against the first support rod 104 by the first actuating part 114 can refer to the position and time at which the first actuating part 114 pushes against the first support rod 104 when the first actuating part 114 moves in a circular motion around the main rod 102. In other words, adjusting the rotation speed of the turntable assembly 106 can change the swing frequency of the first support rod 104. Accordingly, when the active layer 112 is provided with multiple first support rods 104, the turntable assembly 106 can sequentially push the multiple first support rods 104 on the active layer 112 according to the rotation direction (such as clockwise or counterclockwise rotation), so that the dynamic Christmas tree 100 presents a dynamic visual effect of intermittently swinging branches (one or more first support rods 104).

[0048] In some embodiments, such as Figure 6 and Figure 7 As shown. The more the top end 114a of the first actuating part 114 extends beyond the first support rod 104, the greater the sway amplitude of the first support rod 104. The less the top end 114a of the first actuating part 114 extends beyond the first support rod 104, the smaller the sway amplitude of the first support rod 104. Accordingly, the dynamic Christmas tree 100 can determine the height of the first actuating part 114 (i.e., the distance between the top end 114a and the bottom end 114b) based on the sway amplitude of the first support rod 104.

[0049] In some embodiments, such as Figure 1 , Figure 2 , Figure 8 and Figure 9As shown in the diagram, the dynamic Christmas tree 100 further includes a second support rod 116 and a connecting line 118. The second support rod 116 is connected to the main rod 102 and located in a driven layer 120 between the active layer 112 and the bottom 110. One end of the connecting line 118 is connected to the second support rod 116, and the other end is connected to either the first support rod 104 or the turntable assembly 106, with the connecting line 118 located outside the turntable assembly 106. The turntable assembly 106 is linked to the second support rod 116 according to the connecting line 118. For example, the second support rod 116 may refer to a branch of the dynamic Christmas tree 100. The driven layer 120 is located between the active layer 112 and the bottom 110, and its position is determined by the location of the second support rod 116 on the main rod 102. The driven layer 120 may have at least one second support rod 116. At least one second support rod 116 may be arranged in a ring around the surface of the main rod 102. Multiple second support rods 116 can be arranged around the main rod 102 at the same or different heights. The first support rod 104 and the second support rod 116 at the same circumferential position on the main rod 102 are connected to each other by connecting lines 118 (e.g., ...). Figure 8 and Figure 9 (As shown). Accordingly, when the first support rod 104 is pushed by the first actuating part 114, the connected second support rod 116 can be moved through the connecting line 118, causing the second support rod 116 to swing relative to the main rod 102 simultaneously (this could mean the second support rod 116 swings towards the top 108 or swings in the Y-axis direction towards the bottom 110). In some embodiments, the first support rod 104 and the main rod 102 have a first swing angle, and the second support rod 116 and the main rod 102 have a second swing angle, the first swing angle being greater than or equal to the second swing angle. The first swing angle and / or the second swing angle are less than or equal to 60 degrees. In some embodiments, such as Figure 2 As shown, the active layer 112 and the driven layer 120 are separable from each other. That is, the main rod 102 of the active layer 112 is detachably connected to the main rod 102 of the driven layer 120. Accordingly, when assembling or disassembling the turntable assembly 106 to the main rod 102, the active layer 112 and the two main rods 102 of the driven layer 120 can be separated, so that the turntable assembly 106 can be assembled to the main rod 102 of the driven layer 120. In some embodiments, the turntable assembly 106 can be screwed to the main rod 102.

[0050] In some embodiments, such as Figure 8 , Figure 9 and Figure 13As shown. One end of the connecting line 118 is connected to the second support rod 116, and the other end is connected to the turntable assembly 106 (which may be connected to the top cover 127 described later). The turntable assembly 106 further has a second actuating part 122. The second actuating part 122 extends toward the connecting line 118. The first actuating part 114 and the second actuating part 122 are offset from each other in the circumferential position of the turntable assembly 106. When actuated, the turntable assembly 106 drives the first actuating part 114 and the second actuating part 122 to move around the main rod 102 to intermittently push (pull) the connecting line 118. Specifically, the second actuating part 122 may push the connecting line 118 away from the main rod 102, so that the connecting line 118 can pull the second support rod 116 with the top cover 127 as a fulcrum. Figure 13 As shown, the connecting line 118 is connected to the top cover 127 via an adjusting buckle to adjust the tightness of the connecting line 118.

[0051] In some embodiments, the second actuating part 122 may be disposed on a different plane from the first actuating part 114. Figure 6 and Figure 8 For example, the turntable assembly 106 includes a fixed disk 124, a turntable 126, and a drive assembly 128. The fixed disk 124 has a central shaft hole 125, which is fixed to the main rod 102 around the central shaft hole 125. The turntable 126 is movably connected to the fixed disk 124. The turntable 126 has an upper surface 130 and a side surface 132. A first actuating part 114 is located on the upper surface 130, and a second actuating part 122 is located on the side surface 132. In some embodiments, the second actuating part 122 may be disposed on the same plane as the first actuating part 114. For example, both the first actuating part 114 and the second actuating part 122 are disposed on the upper surface 130 (not shown in the figure), and are respectively disposed at different circumferential positions on the upper surface 130.

[0052] In some embodiments, such as Figure 9 As shown. The first actuating part 114 and the second actuating part 122 can be spherical or arc-shaped structures. When the first actuating part 114 contacts the first support rod 104, the first support rod 104 can be guided by the spherical, conical, or arc-shaped structure of the first actuating part 114, and thus move along the surface of the first actuating part 114. Similarly, when the second actuating part 122 contacts the connecting line 118, the connecting line 118 can be guided by the spherical, conical, or arc-shaped structure of the second actuating part 122, and thus move along the surface of the second actuating part 122.

[0053] In some embodiments, such as Figure 3 and Figure 6As shown. The dynamic Christmas tree 100 further includes a controller 134. The controller 134 generates a drive signal, which actuates the turntable assembly 106. Specifically, the drive assembly 128 drives the turntable 126 to rotate relative to the main rod 102 according to the drive signal. The controller 134 may be, for example, an integrated circuit capable of driving and controlling a motor. The controller 134 may be located inside the turntable assembly 106 (in the space between the fixed plate 124 and the turntable 126) and electrically connected to the drive assembly 128 for control. Alternatively, it may be located outside the turntable assembly 106 and control the drive assembly 128 via wired or wireless means. The drive signal can control the rotational speed or oscillation frequency of the drive assembly 128. For example, the drive assembly 128 may be pre-programmed with a control program, and the drive assembly 128 may execute the preset control program according to the drive signal to perform corresponding actions. Alternatively, the drive signal may be a pulse-width modulation (PWM) signal. The drive assembly 128 can adjust the current input to the drive assembly 128 according to the duty cycle of the pulse width modulation signal to change the rotation speed or oscillation frequency. It should be noted that the turntable assembly 106 can predetermine the range of the oscillation angle (i.e., the oscillation stroke) so that the turntable assembly 106 can repeatedly oscillate back and forth at a preset angle.

[0054] In some embodiments, such as Figure 6 As shown. The inner edge of the side surface 132 of the turntable 126 has an annular toothed portion 136. A receiving portion 138 is provided between the turntable 126 and the fixed disk 124, and a drive assembly 128 is disposed in the receiving portion 138. The drive assembly 128 includes a driven gear 140 and a motor unit 142. The motor unit 142 can be a synchronous motor or a stepper motor. The driven gear 140 meshes with the annular toothed portion 136, and the motor unit 142 drives the driven gear 140 according to a drive signal. The driven gear 140 can be directly or indirectly driven by the motor unit 142. Figure 6 As shown, one end of the motor unit 142 has a gear that drives a driven gear 140, which in turn drives the turntable 126. In some embodiments, the driven gear 140 may also be directly connected to one end of the motor unit 142 (see...). Figure 10 ).

[0055] In some embodiments, such as Figure 10 As shown. The annular tooth 136 may also be disposed on the side surface 132. The drive assembly 128 is disposed on the fixed disk 124. The drive assembly 128 includes a driven gear 140 and a motor unit 142. The driven gear 140 meshes with the annular tooth 136, and the motor unit 142 is used to drive the driven gear 140 according to the drive signal.

[0056] In some embodiments, such as Figure 1 , Figure 2, Figure 3 and Figure 6 As shown. The upper surface 130 has a first light-emitting unit 144, which generates a first light beam toward the top 108 according to a driving signal. The fixed disk 124 has a second light-emitting unit 146, which generates a second light beam toward the bottom 110 according to a driving signal. Specifically, the first light-emitting unit 144 and the second light-emitting unit 146 can be light-emitting diodes. The first light-emitting unit 144 and the second light-emitting unit 146 are respectively exposed on the fixed disk 124 and the turntable 126, so that the first light beam and the second light beam can respectively illuminate the top 108 or the bottom 110. It should be noted that the first light-emitting unit 144 and the second light-emitting unit 146 can each have a light driver chip 147. The light driver chip 147 can control the brightness or flashing frequency of the first light-emitting unit 144 or the second light-emitting unit 146 according to the duty cycle of the driving signal. Accordingly, the first light-emitting unit 144 and the second light-emitting unit 146 can produce light-emitting effects such as gradual brightness or flashing. In some embodiments, the first light-emitting unit 144 and the second light-emitting unit 146 may also be disposed on the first support rod 104 or the second support rod 116 (e.g., Figure 1 (As shown). For example, the first light-emitting unit 144 is disposed on the first support rod 104 so that the first light can illuminate the top 108, and the second light-emitting unit 146 is disposed on the second support rod 116 so that the second light can illuminate the bottom 110, thereby forming a projection light corresponding to the top and bottom of the tree.

[0057] In some embodiments, such as Figure 3 As shown. The first light-emitting unit 144 and the second light-emitting unit 146 can be packaged with the light driver chip 147 as a single integrated circuit, and disposed in at least one of the top 108, the active layer 112, the driven layer 120, and the bottom 110. The first light-emitting unit 144 and the second light-emitting unit 146 are respectively connected to the controller 134 via two wires. The first light-emitting unit 144 and the second light-emitting unit 146 each have a light driver chip 147, which is used to selectively drive the first light-emitting unit 144 and the second light-emitting unit 146 according to the driving signal (described in detail later). In some embodiments, such as Figure 3As shown, the first light-emitting unit 144 and the second light-emitting unit 146 can also be connected in series with two power supply wires to form a controllable LED string 20. The LED string 20 can be arranged by the user on the dynamic Christmas tree 100, for example, suspended from the first support pole 104 and / or the second support pole 116. It should be noted that the LED string 20 includes the first light-emitting unit 144 and the second light-emitting unit 146 connected in series with two wires. The light driver chip 147 of the first light-emitting unit 144 and the light driver chip 147 of the second light-emitting unit 146 can be sequentially set with address codes, and the controller 134 can control the first light-emitting unit 144 or the second light-emitting unit 146 at a specified address according to the address code (described in detail later).

[0058] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown. The driving signal can be transmitted through power lines (which can be positive and negative wires), and the driving signal can refer to a combination of signals that generate high or low levels on the power lines. For example, when the driving signal is at a high level (positive voltage), the first light-emitting unit 144 and the second light-emitting unit 146 can generate a first light and a second light, respectively. When the driving signal is at a low level (negative voltage, which can be 0V), the first light-emitting unit 144 and the second light-emitting unit 146 will not generate the first light and the second light (they will be in an off state). In some embodiments, control commands can be carried over the driving signal. When the controller 134 receives the driving signal, it can ignore the control command and control the turntable assembly 106 only with the driving signal. When the light driver chip 147 receives the driving signal, it can control the first light-emitting unit 144 and the second light-emitting unit 146 according to the control command. In some embodiments, the controller 134 can carry control command and communication command signals over the driving signal. The communication command signal has address codes for the first light-emitting unit 144 and the second light-emitting unit 146. The light driver chip 147 of the first light-emitting unit 144 or the second light-emitting unit 146 can selectively drive the first light-emitting unit 144 or the second light-emitting unit 146 according to the address code of the communication command signal. For example, if the address code of the carrier-driven signal corresponds to the first light-emitting unit 144, only the light driver chip 147 of the first light-emitting unit 144 will execute the control command, while the second light-emitting unit 146 will not execute the control command. Conversely, if the address code of the carrier-driven signal corresponds to the second light-emitting unit 146, only the light driver chip 147 of the second light-emitting unit 146 will execute the control command, while the first light-emitting unit 144 will not execute the control command.

[0059] In some embodiments, the control command includes a reset command. The light driver chip 147 resets the preset control timing according to the reset command. For example, when the light driver chip 147 receives a drive signal (i.e., obtains power through power supply), the light driver chip 147 can execute the corresponding light emission mode (e.g., blinking, breathing, candle flashing, or star flashing) according to the preset control timing. When the light driver chip 147 receives a reset command, the preset control timing of the light driver chip 147 will be reset. By setting the transmission interval of the reset command, the light driver chip 147 can maintain a constantly lit or constantly dim light emission effect. It should be noted that since the communication command signal and the reset command carrier are transmitted to the two power supply lines at a frequency of more than 10 ms per second (milliseconds), and the pulse width of the reset command is set to be greater than 1 microsecond to several milliseconds, the impact of the communication command signal and the reset command on the light-emitting units (144, 146) is less than the time it takes for the human eye to perceive a change in light emission, and does not affect the visual effect of the light emission. In addition, the drive component 128 can also ignore signals with pulse widths greater than 1 microsecond to several milliseconds, so that the motor unit 142 can control the rotation speed of the turntable 126 without being disturbed by the reset command.

[0060] In some embodiments, the dynamic Christmas tree 100 may be designed as the aforementioned fixed or movable first support rod 104, allowing the turntable assembly 106 to actuate the first support rod 104. For example, such as Figure 11 and Figure 12 As shown. The dynamic Christmas tree 100 further includes a hook and latch 148. The hook and latch 148 has a hook portion 150 and a stop portion 152 at each end. The hook portion 150 engages with the first support rod 104, and the stop portion 152 normally abuts against the upper surface 130, and the stop portion 152 is located on the movement trajectory of the first actuating part 114. Accordingly, depending on the extension length of the stop portion 152, the height of the first actuating part 114 can be reduced or the swing amplitude of the first support rod 104 can be increased. The stop portion 152 can also be a curved surface to reduce the friction between the stop portion 152 and the first actuating part 114. The turntable assembly 106 can also be applied to a general Christmas tree. The user can set the hook and latch 148 on the tree branch, and the turntable assembly 106 can intermittently actuate the stop portion 152 of the hook and latch 148 to simultaneously raise the hook and latch 148 and the first support rod 104, so that the tree branch produces a swinging effect. In some embodiments, the hook portion 150 further has an opening 151, the width of which is less than or equal to the diameter of the first support rod 104. When the first support rod 104 passes through the opening 151, the hook member 148 may, due to its own material elasticity, slightly expand the width of the opening 151, so that the first support rod 104 can pass through the opening 151 and be confined within the hook portion 150.

[0061] In some embodiments, such as Figure 13 and Figure 14As shown. The turntable assembly 106 further includes a top cover 127. The top cover 127 covers the turntable 126. The distance between the top cover 127 and the fixed plate 124 can be maintained by a bracket 129, allowing the turntable 126 to rotate smoothly between the top cover 127 and the fixed plate 124. The top cover 127 has at least one through hole 131. Each through hole 131 corresponds to a hook 148 on a plumb line, and each hook 148 extends into the corresponding through hole 131. When the first actuating part 114 actuates the hook 148, the hook 148 will rise or fall within the range of the through hole 131. Here, the first actuating part 114 actuates the hook fastener 148 according to the circumferential movement trajectory. The through hole 131 can limit the hook fastener 148 laterally (in the X-axis direction in the figure) to prevent the hook fastener 148 from deviating from the trajectory of the first actuating part 114. In some embodiments, the top cover 127, the fixing plate 124, and the turntable 126 are disassembled or assembled to the main rod 102 according to the central shaft hole 125. As mentioned above, the turntable assembly 106 can be cut open from the central shaft hole 125 to form a symmetrical and separable assembly. In this embodiment, the top cover 127, the fixing plate 124, and the turntable 126 are disassembled into a half-assembled piece according to the central shaft hole 125 for disassembly or assembly to the main rod 102.

[0062] In some embodiments, such as Figure 1 and Figure 10 As shown. The dynamic Christmas tree 100 further includes a connecting rod 154. The connecting rod 154 is disposed on the active layer 112. The connecting rod 154 has a fixed section 156 and a movable section 158. One end of the fixed section 156 is connected to the main rod 102, and one end of the movable section 158 is pivotally connected to the other end of the fixed section 156. The first support rod 104 is connected to the other end of the movable section 158. The first moving part 114 can push the movable section 158 to indirectly drive the first support rod 104. When the user wants to store the dynamic Christmas tree 100, each of the first support rods 104 can also reduce the overall volume of the dynamic Christmas tree 100 by folding the movable section 158 to the main rod 102.

[0063] In some embodiments, such as Figure 15 As shown. The dynamic Christmas tree 100 further includes a rotating connection assembly 160 and a top rod 162. One end of the rotating connection assembly 160 is connected to the top 108 of the main rod 102. The top rod 162 is connected to the other end of the rotating connection assembly 160. The rotating connection assembly 160 is used to rotate the top rod 162 according to a drive signal. Accordingly, when the rotating connection assembly 160 rotates the top rod 162, the top rod 162 can rotate horizontally relative to the main rod 102 (rotation in the X-axis direction in the figure can be clockwise or counterclockwise). In some embodiments, such as Figure 15As shown. The main pole 102 is assembled from a first pole body 102a and a second pole body 102b. The first pole body 102a and the second pole body 102b each have an active layer 112 and a driven layer 120, respectively. One end of the rotary connecting assembly 160 is connected to the bottom 110 of the first pole body 102a, and the other end is connected to the top 108 of the second pole body 102b. The rotary connecting assembly 160 is used to rotate the first pole body 102a according to a drive signal. Accordingly, if the dynamic Christmas tree 100 has multiple active layers 112 and driven layers 120, the rotary connecting assembly 160 can be disposed between the segments of the main pole 102 to control the operation of the turntable assembly 106 and the first light-emitting unit 144 or the second light-emitting unit 146 in different segments. The control of these different segments can be synchronous or asynchronous, and the controller 134 can communicate command signals to determine the operation of different segments (such as rotation speed, swing frequency, swing angle, rotation angle, or the aforementioned lighting effects). For example, controller 134 can control the swing angle of the turntable assembly 106 in the first rod 102a to be greater than the swing angle of the turntable assembly 106 in the second rod 102b. The height of the second rod 102b may be close to the height of a child, thus reducing the swing angle of the turntable assembly 106 in the second rod 102b. This prevents the first support rod 104 or the second support rod 116 of the second rod 102b from pushing over a child and causing an accident.

[0064] In some embodiments, such as Figure 15 and Figure 16 As shown. The rotating connection assembly 160 includes a base 163, a rotor 164, and a motor 165. The base 163 can be connected to the top 108 of the main rod 102 (which can be the top 108 of the first rod 102a or the second rod 102b). The base 163 can be electrically connected to the controller 134 via two wires to receive drive signals. The two ends of the rotor 164 are respectively connected to the base 163 and the top rod 162. The rotor 164 can also be connected to the bottom 110 of either the first rod 102a or the second rod 102b. The motor 165 is connected to the base 163 to drive the rotor 164 to rotate according to the drive signal. The motor 165 can be electrically connected to the controller 134 via two wires passing through the base 163 to receive drive signals.

[0065] In some embodiments, the rotary connection assembly 160 further includes a bearing 166 and a connecting bracket 168. The bearing 166 is pivotally mounted on the motor 165 (outer edge of the shaft 167 of the motor 165) and has two first electrodes 170. The base 163 has two second electrodes 172, which surround the bearing 166 and are electrically connected to the two first electrodes 170 respectively. The connecting bracket 168 is located between the base 163 and the rotor 164 and surrounds the motor 165. One side of the rotor 164 has an electrical connection terminal 174, and one side of the connecting bracket 168 has an electrical connection socket 176. The electrical connection terminal 174 is connected to the electrical connection socket 176, and the electrical connection socket 176 is electrically connected to the two first electrodes 170 to drive the rotor 164 and the connecting bracket 168 to rotate synchronously. The drive assembly 128, the controller 134, the first light-emitting unit 144, the second light-emitting unit 146, and the motor 165 can be connected by two wires to form a control loop. Specifically, when the motor 165 rotates according to the drive signal, the two wires can simultaneously transmit the drive signal sequentially through the two second electrodes 172, the two first electrodes 170, and the electrical connection socket 176 to the electrical connection terminal 174. The light-emitting units (144, 146) can be electrically connected to the electrical connection terminal 174 via wires to emit light according to the drive signal. Here, the main rod 102 can transmit drive signals to the turntable assemblies 106 or light-emitting units (144, 146) in different segments through the cascading of the rotary connection assembly 160, allowing the controller 134 to simultaneously control the vertical swaying, horizontal rotation, or lighting effects of different segments of the branches. In some embodiments, the number of electrical connection sockets 176 and electrical connection terminals 174 can be multiple. In some embodiments, such as Figure 16 As shown. The connecting bracket 168 can be assembled by connecting multiple brackets. For example, the upper bracket is provided with an electrical connection socket 176, and the lower bracket is provided with a bearing 166, to facilitate production and assembly.

[0066] In some embodiments, the rotor 164 includes a connecting sleeve 169, which is sleeved on the rotating shaft 167, causing the rotating shaft 167 to drive the rotor 164 to rotate. In some embodiments, the connecting sleeve 169 further includes a guide opening 171 for guiding the rotor 164 into the connecting sleeve 169. Specifically, the guide opening 171 is funnel-shaped from the rotor 164, and the inclined surface of the guide opening 171 can guide the rotor 164 to extend into the connecting sleeve 169.

[0067] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown. The dynamic Christmas tree 100 further includes a sensor 178. The sensor 178 is electrically connected to the controller 134. The sensor 178 generates a sensing signal when actuated. The controller 134 can adjust the drive signal based on the sensing signal. The sensor 178 can be a distance sensor, a brightness sensor, an ultrasonic sensor, an infrared sensor, or a sound wave sensor. Taking a sound wave sensor as an example, the sensor 178 can generate a first sensing signal and a second sensing signal based on the received sound wave magnitude, where the first sensing signal is greater than the second sensing signal. The controller 134 can increase the rotation speed of the turntable assembly 106 based on the first sensing signal, or decrease the rotation speed of the turntable assembly 106 based on the second sensing signal. The light driver chip 147 can increase the brightness or flashing frequency of the light-emitting units (144, 146) based on the first sensing signal, or decrease the brightness or flashing frequency of the light-emitting units (144, 146) based on the second sensing signal. Accordingly, the louder the ambient sound (which could refer to the ambient music surrounding the dynamic Christmas tree 100) (or the more rapid the melody), the higher the swing frequency of the first support rod 104 and / or the second support rod 116, and the brighter or faster the flashing frequency of the light-emitting units (144, 146). Conversely, the quieter the ambient sound (or the slower the melody), the lower the swing frequency of the first support rod 104 and / or the second support rod 116, and the dimmer or slower the flashing frequency of the light-emitting units (144, 146). It should be noted that the controller 134 can determine the environmental changes and the feedback action of the dynamic Christmas tree 100 based on the type of sensor 178 used and the magnitude of the sensed values. Taking an infrared sensor as an example, when the sensor 178 senses an object (which could refer to a human or animal) approaching, the dynamic Christmas tree 100 can increase its swing speed or enhance its lighting effect. Conversely, when sensor 178 detects an object (which could be a human or animal) moving away or does not detect an object, the dynamic Christmas tree 100 reduces its swing speed or reduces its lighting effect (or stops lighting altogether) to save power. In some embodiments, sensor 178 can also be electrically connected to controller 134 and light driver chip 147 respectively, so that controller 134 and light driver chip 147 can respectively actuate drive assembly 128, rotation connection assembly 160 and light-emitting units (144, 146) according to the sensing signal generated by sensor 178.

[0068] In some embodiments, such as Figure 1 and Figure 2As shown. Adjacent active layers 112, driven layers 120, and / or top 108 can form a linkage combination. The dynamic Christmas tree 100 can be equipped with multiple linkage combinations, controlled by the movement of the first support rod 104, the second support rod 116, the rotating connecting assembly 160, and the light-emitting units (144, 146) to increase control variations and visual effects. It should be noted that the main rods 102 of different linkage groups can be connected to each other. For example, the bottom end 114b of the upper main rod 102 can be connected to the top end 114a of the lower main rod 102 to connect the two main rods 102. The connection structure between the main rods 102 can be fixed by interlocking different diameters or connected by additional sleeves.

[0069] In some embodiments, such as Figure 6 or Figure 13 The turntable 126 and driven gear 140 shown can be planetary gear sets. For example, the annular tooth 136 of the turntable 126 can be an outer ring gear, and the driven gear 140 can be a sun gear.

[0070] In some implementations, such as Figure 3 As shown. The dynamic Christmas tree 100 further includes a tilt sensor 180 (e.g., an accelerometer). The tilt sensor 180 can be disposed on the main pole 102, the first support pole 104, the second support pole 116, the turntable assembly 106, or the rotary connection assembly 160. When the tilt sensor 180 detects that the dynamic Christmas tree 100 has tilted beyond a preset angle (e.g., 30 degrees), it can generate a warning signal. The controller 134 can stop sending drive signals based on the warning signal, causing the turntable assembly 106, the rotary connection assembly 160, and the light-emitting units (144, 146) to stop operating, thereby increasing safety. In some embodiments, the tilt sensor 180 can also be a tilt switch, which is used to directly interrupt the power supply to the controller 134, the turntable assembly 106, and the rotary connection assembly 160 when the main pole 102 tilts.

[0071] In some embodiments, the turntable assembly 106 and the rotary connection assembly 160 can be applied to existing Christmas trees. It should be noted that larger Christmas trees will have their trunks divided into detachable segments for easier assembly. The turntable assembly 106 and the rotary connection assembly 160 can be assembled onto the trunks to form a dynamic Christmas tree 100. Since existing Christmas trees are over one meter tall, dividing them into multiple trunk segments reduces the torque requirements of the rotary connection assembly 160.

[0072] In some embodiments, such as Figure 13As shown, the fixed disk 124 has a first positioning point 182, and the turntable 126 has a second positioning point 184. The controller 134 is used to determine that the turntable 126 is at the starting angle when the first positioning point 182 and the second positioning point 184 are connected. Specifically, the first positioning point 182 and the second positioning point 184 serve as origin markers. When the first positioning point 182 and the second positioning point 184 are connected, it indicates that the turntable 126 has rotated to the starting angle, and the controller 134 can position the turntable 126 at the starting angle (motor position reset) based on the electrical signal of the two contacts (182, 184). Accordingly, the rotation control of the turntable 126 by the controller 134 can calibrate the rotation angle of the turntable 126 in real time. It should be noted that when the turntable 126 is at the starting angle, the first support rod 104 and / or the second support rod 116 are in a naturally hanging state.

[0073] In summary, in some embodiments of the dynamic Christmas tree 100, the rotation of the turntable assembly 106 is controlled to directly or indirectly drive the first support rod 104 and the second support rod 116 to swing vertically. Accordingly, the swing sequence of the first support rod 104 and the second support rod 116 can be further controlled according to the travel distance or rotation speed of the turntable assembly 106. The swinging of the support rods (104, 116) in conjunction with the lighting simulates the dynamic effect of tree branches being blown by the wind, satisfying the user's demand for dynamic effects such as Christmas tree swinging and lighting. In some embodiments, different segments of the dynamic Christmas tree 100 can be connected by a rotatable connecting assembly 160. The rotatable connecting assembly 160 can horizontally rotate different segments of the main rod 102 (e.g., the top rod 162, the first rod 102a, or the second rod 102b). Accordingly, different segments of the dynamic Christmas tree 100 (e.g., dividing a two-meter-high tree into three segments) can all perform the same or different vertical swinging, horizontal rotation, or lighting effects.

[0074] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
