Description
Technical Field
[0001] The present invention relates to the technical field of tobacco processing, and particularly relates to a lifting trolley for a cigarette clip group. Background Art
[0002] Tobacco is a widely cultivated and used plant, mainly used for making tobacco products such as cigarettes, cigars, pipe tobacco, and chewing tobacco. When baking tobacco, a cigarette clip group is required to stabilize the tobacco. When the cigarette clip group is placed inside the baking room, a lifting trolley is needed. Since the lateral dimension of the cigarette clip is larger than the size of the entrance inside the baking room, it is difficult for the cigarette clip to enter the baking room horizontally through the lifting trolley. Secondly, since most cigarette clips are directly placed above the lifting rod, the cigarette clips are prone to shift when the trolley moves, which easily affects the placement of the cigarette clips. Summary of the Invention
[0003] The purpose of the present invention is to provide a lifting trolley for a cigarette clip group to solve the problems raised in the above background art, that is, since the lateral dimension of the cigarette clip is larger than the size of the entrance inside the baking room, it is difficult for the cigarette clip to enter the baking room horizontally through the lifting trolley. Secondly, since most cigarette clips are directly placed above the lifting rod, the cigarette clips are prone to shift when the trolley moves, which easily affects the placement of the cigarette clips.
[0004] To achieve the above purpose, the present invention provides the following technical solution: A lifting trolley for a cigarette clip group, including a lifting trolley assembly. The lifting trolley assembly includes a moving frame, movable wheels, an electric lifting rod, a fixed block, a rotating block, and a rotating groove. A stabilizing assembly is arranged on the top of the lifting trolley assembly. The stabilizing assembly includes a stabilizing block, a spring groove, a reset spring, and an arc-shaped clamping block. A cigarette clip assembly is arranged on the outer wall of the stabilizing assembly. The cigarette clip assembly includes a cigarette clip frame, a mounting frame, a mounting groove, and an arc-shaped clamping groove.
[0005] Preferably, the bottom of the moving frame is fixedly connected to the top of the movable wheels, and both sides of the top of the moving frame are respectively fixedly connected to the bottom of the electric lifting rod.
[0006] Preferably, the top end of the electric lifting rod is fixedly connected to the bottom end of the fixed block, and a rotating groove is formed inside the rotating block.
[0007] Preferably, both sides of the fixed block are rotatably connected to the inner wall of the rotating groove through a rotating shaft, and the top of the rotating groove is fixedly connected to the bottom of the stabilizing block.
[0008] Preferably, spring grooves are formed inside both sides of the stabilizing block, and one end of the reset spring is fixedly connected to the inner wall of the spring groove.
[0009] Preferably, the other end of the reset spring is fixedly connected to one end of the arc-shaped clamping block, and the other end of the arc-shaped clamping block is set to be arc-shaped.
[0010] Preferably, the bottom of the cigarette clip holder is fixedly connected to the top of the mounting rack, and a mounting groove is formed inside the mounting rack.
[0011] Preferably, arc-shaped clamping grooves are formed on both sides of the mounting groove, and the inner wall of the arc-shaped clamping groove is movably connected to the arc surface of the arc-shaped clamping block, and the inner wall of the mounting groove is movably connected to the outer wall of the stabilizing block.
[0012] Furthermore, the cigarette clip assembly further includes an electric telescopic rod, a push plate, a pressure sensor, a controller and an inclination sensor; The electric telescopic rod is fixedly connected to one side of the frame of the cigarette clip holder perpendicular to the cigarette hanging rod. The electric telescopic rod is parallel to the cigarette hanging rod, and the end of the electric telescopic rod is connected to the push plate; The push plate is located inside the rectangle formed by the frames of the cigarette clip holder and is perpendicular to the electric telescopic rod. The plane formed by the push plate and the cigarette hanging rod is parallel; A pressure sensor is provided on the side of the push plate opposite to the electric telescopic rod; The inclination sensor is arranged on the cigarette clip holder, and the Z-axis of the inclination sensor is parallel to the plane formed by the cigarette hanging rod; The electric telescopic rod, the pressure sensor and the inclination sensor are electrically connected to the controller.
[0013] A control method for a lifting trolley of a cigarette clip group, the method comprising the following steps: (1) First, the trolley raises the cigarette clip group to a first height through an electric lifting rod, and the first height makes the cigarettes on the cigarette clip suspended; (2) The cylinders on both sides of the trolley lift asymmetrically. One side's moving lifting rod extends, and the other side's moving lifting rod 103 shortens, so that the cigarette clip group rotates in the vertical plane. When the horizontal projection width of the cigarette clip group is less than the size of the entrance of the curing barn at the first angle, the trolley loads the cigarette clip group into the position where the tobacco needs to be loaded in the curing barn; (3) The moving lifting rods on both sides of the trolley lift asymmetrically again. One side's moving lifting rod extends, and the other side's moving lifting rod shortens, opposite to step (2), so that the cigarette clip group returns to the horizontal state; (4) The moving lifting rods 103 on both sides of the trolley descend simultaneously, place the cigarette clip on the cigarette hanging rack, and the trolley completes one cycle of tobacco loading work and exits the curing barn.
[0014] A control method for a lifting trolley of a cigarette clip group, the method comprising the following steps: The inclination sensor obtains the inclination angle a and sends it to the controller; The pressure sensor obtains the pressure value P and sends it to the controller; The controller caches the historical values of a and p; The controller determines that if the historical value a in the cache is greater than the first inclination angle only once, it controls the electric telescopic rod to extend. If P is always less than the first pressure value during the extension process, the electric telescopic rod retracts to the shortest length. When the historical value a in the cache is greater than the first inclination angle twice, the controller controls the electric telescopic rod to extend. During the extension process, P is kept less than the second pressure value until the inclination angle is less than the second inclination angle and then the historical value a in the cache is greater than the first inclination angle three times. Then the controller controls the electric telescopic rod to retract to the shortest length and clears the cache.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The moving frame moves to the entrance of the baking room through the movable wheels. One group of the two sets of electric lifting rods moves upward and the other moves downward, thereby driving the two sets of electric lifting rods to move respectively. At the same time, the rotation of the rotating block makes the cigarette clip holder tilt. Due to the tilt of the cigarette clip holder, the cigarette clip holder can enter the entrance of the baking room. When it enters the baking room, through the lifting of the two sets of electric lifting rods, the cigarette clip holder is reset to a horizontal state. At the same time, the cigarette clip holder is blocked at the entrance of the baking room. Then the electric lifting rods move downward uniformly, so that the arc surface of the arc-shaped block is squeezed by the arc-shaped card slot. The arc-shaped block is squeezed and enters the inside of the spring groove, so that the mounting frame and the stabilizing block are disengaged from the engaged state. As the electric lifting rod moves downward, it drives the stabilizing block away from the inside of the mounting groove, so that the cigarette clip holder is placed inside the baking room. By tilting the cigarette clip holder, the cigarette clip holder can enter the inside of the baking room. The cigarette clip holder is placed above the stabilizing block. At the same time, the stabilizing block enters the inside of the mounting groove. The bottom of the mounting frame squeezes the arc surface of the arc-shaped block, so that the arc-shaped block squeezes the return spring. When the stabilizing block completely enters the inside of the mounting groove, the return of the return spring drives the arc-shaped block into the inside of the arc-shaped card slot, thereby stabilizing the cigarette clip holder, facilitating the stabilization of the cigarette clip holder, and at the same time, the cigarette clip holder can remain stable when it is tilted and placed inside the baking room.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0019] Embodiment 1: Please refer to Figures 1-4 , the present invention provides a technical solution: including a lifting trolley assembly 1, the lifting trolley assembly 1 includes a moving frame 101, a movable wheel 102, an electric lifting rod 103, a fixed block 104, a rotating block 105 and a rotating groove 106. A stabilizing assembly 2 is arranged on the top of the lifting trolley assembly 1, the stabilizing assembly 2 includes a stabilizing block 201, a spring groove 202, a return spring 203 and an arc-shaped clamping block 204. A cigarette clip assembly 3 is arranged on the outer wall of the stabilizing assembly 2, and the cigarette clip assembly 3 includes a cigarette clip holder 301, a mounting frame 302, a mounting groove 303 and an arc-shaped clamping groove 304.
[0020] In one embodiment, the bottom of the moving frame 101 is fixedly connected to the top of the movable wheel 102, and both sides of the top of the moving frame 101 are fixedly connected to the bottom of the electric lifting rod 103.
[0021] Specifically: by moving one group of the two electric lifting rods 103 upward and the other group downward, the two electric lifting rods 103 are respectively driven to move. At the same time, the cigarette clip holder 301 is tilted by the rotation of the rotating block 105. Through the tilting of the cigarette clip holder 301, the cigarette clip holder 301 can enter the entrance of the baking room.
[0022] In one embodiment, the top end of the electric lifting rod 103 is fixedly connected to the bottom end of the fixed block 104, and a rotating groove 106 is opened inside the rotating block 105.
[0023] Specifically: the cigarette clip holder 301 is tilted by the rotation of the rotating block 105, ensuring the stability of the cigarette clip holder 301 after tilting.
[0024] In one embodiment, both sides of the fixed block 104 are rotatably connected to the inner wall of the rotating groove 106 through rotating shafts, and the top of the rotating groove 106 is fixedly connected to the bottom of the stabilizing block 201.
[0025] Specifically: by tilting the cigarette clip holder 301, the cigarette clip holder 301 can enter the interior of the baking room.
[0026] In one embodiment, spring grooves 202 are formed inside both sides of the stabilizing block 201, and one end of a return spring 203 is fixedly connected to the inner wall of the spring groove 202.
[0027] Specifically: the cigarette clip holder 301 is reset to a horizontal state, and at the same time, the cigarette clip holder 301 is blocked at the entrance of the baking room. Then, the electric lifting rod 103 moves downward uniformly, so that the arc surface of the arc-shaped block 204 is squeezed by the arc-shaped groove 304. The arc-shaped block 204 is squeezed and enters the interior of the spring groove 202, so that the mounting bracket 302 and the stabilizing block 201 are disengaged from the engaged state.
[0028] In one embodiment, the other end of the return spring 203 is fixedly connected to one end of the arc-shaped block 204, and the other end of the arc-shaped block 204 is set to be arc-shaped.
[0029] Specifically: the return of the return spring 203 drives the arc-shaped block 204 to enter the interior of the arc-shaped groove 304, thereby stabilizing the cigarette clip holder 301.
[0030] In one embodiment, the bottom of the cigarette clip holder 301 is fixedly connected to the top of the mounting bracket 302, and a mounting groove 303 is formed inside the mounting bracket 302.
[0031] Specifically: it facilitates the stabilization of the cigarette clip holder 301, and at the same time, the cigarette clip holder 301 can remain stable when being tilted and placed into the interior of the baking room.
[0032] In one embodiment, arc-shaped grooves 304 are formed on both sides of the mounting groove 303, and the inner wall of the arc-shaped groove 304 is movably connected to the arc surface of the arc-shaped block 204. The inner wall of the mounting groove 303 is movably connected to the outer wall of the stabilizing block 201.
[0033] Specifically: through the movable connection between the inner wall of the arc-shaped groove 304 and the arc surface of the arc-shaped block 204, the arc-shaped block 204 can get rid of the limiting state by the downward force of the electric lifting rod 103.
[0034] The cigarette clip holder 301 is placed above the stabilizing block 201. At the same time, the stabilizing block 201 enters the interior of the installation groove 303. The bottom of the mounting frame 302 presses against the arc surface of the arc-shaped clamping block 204, causing the arc-shaped clamping block 204 to press against the return spring 203. When the stabilizing block 201 completely enters the interior of the installation groove 303, the return of the return spring 203 drives the arc-shaped clamping block 204 into the interior of the arc-shaped clamping groove 304, thereby stabilizing the cigarette clip holder 301. The moving frame 101 moves to the entrance of the baking room through the movable wheels 102. One set of the two groups of electric lifting rods 103 moves upward and the other moves downward, thereby driving the two groups of electric lifting rods 103 to move respectively. At the same time, the rotation of the rotating block 105 causes the cigarette clip holder 301 to tilt. Due to the tilt of the cigarette clip holder 301, the cigarette clip holder 301 can enter the entrance of the baking room. When entering the baking room, through the lifting of the two groups of electric lifting rods 103, the cigarette clip holder 301 is reset to a horizontal state. At the same time, the cigarette clip holder 301 is blocked at the entrance of the baking room. Then the electric lifting rods 103 move downward uniformly, causing the arc surface of the arc-shaped clamping block 204 to be pressed by the arc-shaped clamping groove 304. The arc-shaped clamping block 204 is pressed and enters the interior of the spring groove 202, causing the mounting frame 302 and the stabilizing block 201 to get out of the clamped state. As the electric lifting rods 103 move downward, the stabilizing block 201 is driven away from the interior of the installation groove 303, placing the cigarette clip holder 301 inside the baking room. This is the working principle of the cigarette clip group lifting trolley.
[0035] Further, referring to Figure 6 , the cigarette clip assembly 3 further includes an electric telescopic rod 306, a push plate 305, a pressure sensor 307, a controller 308, and an inclination sensor 309; The electric telescopic rod 306 is fixedly connected to one side of the frame of the cigarette clip holder 301 that is perpendicular to the hanging cigarette rod 3010. The electric telescopic rod 306 is parallel to the hanging cigarette rod 3010, and the end of the electric telescopic rod 306 is linked to the push plate 305; The push plate 305 is located inside the rectangle formed by the frame of the cigarette clip holder 301 and is perpendicular to the electric telescopic rod 306. The plane formed by the push plate 305 and the hanging cigarette rod 3010 is parallel; A pressure sensor 307 is provided on the side of the push plate 305 opposite to the electric telescopic rod 306; The inclination sensor 309 is arranged on the cigarette clip holder 301. The Z-axis of the inclination sensor 309 is parallel to the plane formed by the hanging cigarette rod 3010; The electric telescopic rod 306, the pressure sensor 307, and the inclination sensor 309 are electrically connected to the controller 308.
[0036] Embodiment 2: The current width of the curing barn is 2700 mm, and the standard sizes of the tobacco clamps are 1320, 1340, and 1380. Due to the structural beams inside the curing barn for supporting the flue-cured tobacco, the transverse dimension of the tobacco clamp is larger than the entrance dimension of the curing barn, and the tobacco clamp cannot be translated into the curing barn. Assuming that 10 tobacco clamps are grouped as a whole for loading tobacco, and the size of each tobacco clamp is 1320 * 100 mm with no gap between the tobacco clamps, the total width is 1000 mm. The tobacco clamps are translated into the curing barn with the 1000 mm end dimension outside the curing barn, and then rotated 90 degrees horizontally after entering the curing barn. The rotation line of the tobacco clamp group exceeds the transverse dimension of the curing barn, indicating that this solution is not feasible.
[0037] To solve this problem, this embodiment refers to Figure 5 and proposes a control method for the lifting trolley of the tobacco clamp group. The method includes the following steps: (1) First, the trolley raises the tobacco clamp group to the first height through the electric lifting rod 103. The first height makes the tobacco on the tobacco clamp suspended, as shown in Figure 5 (a); (2) The cylinders on both sides of the trolley lift asymmetrically. One moving lifting rod 103 extends, and the other moving lifting rod 103 shortens, so that the tobacco clamp group rotates in the vertical plane. When the horizontal projection width of the tobacco clamp group is less than the entrance dimension of the curing barn after rotating to the first angle, the trolley loads the tobacco clamp group into the position where tobacco needs to be loaded in the curing barn, as shown in Figure 5 (b); (3) The moving lifting rods 103 on both sides of the trolley lift asymmetrically again. One moving lifting rod 103 extends, and the other moving lifting rod 103 shortens, which is opposite to step (2), so that the tobacco clamp group returns to the horizontal state, as shown in Figure 5 (c); (4) The moving lifting rods 103 on both sides of the trolley descend simultaneously, place the tobacco clamps on the tobacco hanging rack, and the trolley completes one cycle of tobacco loading work and exits the curing barn, as shown in Figure 5 (d / e).
[0038] Embodiment 3: This embodiment aims to solve the problem in the prior art that due to the differences in the sizes of different types and baking degrees of tobacco leaves, there are gaps left in the tobacco clamp group to avoid damaging the tobacco leaves when clamping the tobacco leaves. As a result, the tobacco leaves are relatively loose on the tobacco clamp group, making it easy for the trolley to loosen the tobacco leaves during the transfer process (especially during the tilting operation). For this reason, this embodiment further defines a specific control method for the lifting trolley of the tobacco clamp group. This method utilizes the additional electric telescopic rod 306, push plate 305, pressure sensor 307, controller 308, and inclination sensor 309 in the tobacco clamp assembly 3, referring to Figure 7 and its specific steps are as follows: Signal acquisition and transmission: The inclination sensor 309 monitors the inclination angle α of the tobacco clip holder 301 in real time and sends the angle value to the controller 308. At the same time, the pressure sensor 307 is located on the push plate 305 to monitor the pressure value P exerted by the push plate 305 on the tobacco leaves in real time and sends the pressure value to the controller 308.
[0039] Data caching: The controller 308 receives and stores (caches) the historical measurement values of the inclination angle α and the pressure P for subsequent logical judgment.
[0040] Control logic and action execution: The controller 308 executes the following judgment and control sequence based on the cached historical data: Initial inclination detection and preliminary stabilization attempt: The controller 308 determines that if there is only one recorded value greater than the preset "first inclination threshold" (indicating that the tobacco clip group has started to tilt significantly) in the cached historical inclination angle values α. At this time, the controller 308 controls the electric telescopic rod 306 to start extending, driving the push plate 305 to move towards the tobacco leaves.
[0041] Pressure feedback and stabilization abort: During the extension of the electric telescopic rod 306, the controller 308 continuously monitors the pressure value P fed back by the pressure sensor 307. If the pressure P fails to reach the preset "first pressure threshold" throughout the extension process (meaning that the push plate fails to effectively contact or exert sufficient stabilizing force on the tobacco leaves, perhaps the tobacco leaves are already relatively stable or sparse), then the controller 308 determines that this stabilization operation is ineffective or unnecessary and controls the electric telescopic rod 306 to fully retract to the shortest state.
[0042] Secondary inclination detection and continuous stabilization operation: When the controller 308 determines that there are already two recorded values greater than the "first inclination threshold" in the cached historical inclination angle values α (which may correspond to a specific stage during the process of tilting into the curing barn), the controller 308 controls the electric telescopic rod 306 to extend again (or continue to extend).
[0043] Pressure control and angle monitoring: During this extension process, the goal of the controller 308 is to exert an effective stabilizing force while avoiding damaging the tobacco leaves. Therefore, it adjusts the extension of the electric telescopic rod 306 to ensure that the pressure P is always less than the preset "second pressure threshold" (a safe upper limit pressure). This stable state will be maintained until the controller 308 detects that the inclination angle α fed back by the inclination sensor 309 is less than the preset "second inclination threshold" (indicating that the tobacco clip group has approached or returned to a relatively horizontal state).
[0044] Stable End and Reset: When the inclination angle α is less than the "second inclination threshold", and the controller 308 determines that among the cached historical inclination angle values α, there have been three recordings greater than the "first inclination threshold" (which may indicate the completion of a complete tilt-return operation sequence), the controller 308 controls the electric telescopic rod 306 to fully retract to the shortest state, and clears the cached historical inclination angle α and pressure P values to prepare for the next operation cycle.
[0045] Technical Principle Analysis: The core technical principle of the control method proposed in this embodiment lies in using sensor feedback and controller logic to achieve adaptive dynamic stability of the tobacco leaves in the tobacco clip group.
[0046] State Sensing: The function of the inclination angle sensor 309 is to sense the posture of the tobacco clip group in real time, especially its inclination degree. When the inclination angle exceeds the preset threshold (the first inclination threshold), the system recognizes that there is a risk of the tobacco leaves loosening due to the inclination, thereby triggering the stability mechanism. The inclination angle data is not only used for triggering, but the number of its changes is also used by the controller to determine which stage the current operation is in (such as starting to tilt, entering the baking room, restoring horizontal, etc.).
[0047] Active Intervention: The electric telescopic rod 306 and the push plate 305 constitute the active stability execution mechanism. The controller drives the telescopic rod to extend when necessary according to the signal of the inclination angle sensor, and applies a lateral thrust parallel to the hanging tobacco rod 3010 to the tobacco leaves through the push plate, so as to press or support the tobacco leaves to prevent them from sliding or falling during inclination.
[0048] Force Feedback Closed-loop Control: The pressure sensor 307 provides the key force feedback signal. This makes the stability process no longer apply force blindly, but forms a closed-loop control: Effectiveness Judgment: By comparing the pressure P with the first pressure threshold, the system can judge whether the push plate effectively contacts the tobacco leaves and applies the basic stabilizing force. If it cannot be achieved, the operation is aborted to avoid empty strokes or unnecessary energy consumption.
[0049] Overload Protection: By restricting the pressure P not to exceed the second pressure threshold, the system can ensure that the applied stabilizing force can effectively fix the tobacco leaves without being too large to damage the delicate tobacco leaves. This reflects the adaptability to different tobacco leaf conditions.
[0050] Logical Decision-making and Stage Control: The controller 308 is the "brain" of the entire intelligent stability system. It comprehensively processes real-time and historical data from the inclination sensor and the pressure sensor, and precisely controls the actions (extension, retraction, holding) and timing of the electric telescopic rod according to preset logical rules (number of inclination triggers, pressure threshold comparison, inclination recovery judgment). By judging the historical number of inclinations, the controller can distinguish different stages of the operation and execute or cancel the stability action at the appropriate stage. For example, a stability force is applied when tilting into the curing barn, and the stability force is withdrawn after the tobacco clamp group is placed stably or returns to the horizontal.
[0051] In summary, in this embodiment, by integrating inclination and pressure sensing, intelligent decision-making of the controller, and precise execution of the electric telescopic rod, a closed-loop feedback control system is formed. When the tobacco clamp group lifting trolley performs an inclination operation, the system can automatically and moderately physically stabilize the tobacco leaves according to actual needs, effectively solving the problem of loosening caused by different tobacco leaf sizes or clamping gaps, improving the reliability of the tobacco transportation process and the integrity rate of the tobacco leaves, and at the same time avoiding damage to the tobacco leaves.

The plane formed by the push plate (305) and the cigarette hanging rod (3010) is parallel; A pressure sensor (307) is provided on the side of the push plate (305) opposite to the electric telescopic rod (306); The inclination sensor (309) is provided on the cigarette clamping frame (301), and the Z-axis of the inclination sensor (309) is parallel to the plane formed by the cigarette hanging rod (3010); The electric telescopic rod (306), the pressure sensor (307) and the tilt sensor (309) are electrically connected to the controller (308).
9. A control method for the lifting trolley of the cigarette clip group according to claim 7, characterized in that, The method includes the following steps: (1) First, the trolley raises the cigarette clip group to a first height through the electric lifting rod (103), and at the first height, the cigarettes on the cigarette clips are suspended; (2) The cylinders on both sides of the trolley lift asymmetrically. One side's moving lifting rod (103) extends, and the other side's moving lifting rod (103) shortens, so that the cigarette clip group rotates within a vertical plane. When the horizontal projection width of the cigarette clip group is less than the size of the entrance of the curing barn after rotating to a first angle, the trolley loads the cigarette clip group into the position where the cigarettes need to be loaded in the curing barn; (3) The moving lifting rods (103) on both sides of the trolley lift asymmetrically again. One side's moving lifting rod (103) extends, and the other side's moving lifting rod (103) shortens, which is opposite to step (2), so that the cigarette clip group returns to the horizontal state; (4) The moving lifting rods (103) on both sides of the trolley descend simultaneously, place the cigarette clips on the hanging tobacco rack, and the trolley completes one cycle of cigarette loading work and exits the curing barn.
10. A control method for the lifting trolley of the cigarette clip group according to claim 8, characterized in that, The method includes the following steps: The tilt sensor (309) obtains the tilt angle a and sends it to the controller (308); The pressure sensor (307) obtains the pressure value P and sends it to the controller (308); The controller (308) caches the historical values of a and p; The controller (308) determines that if the historical value a in the cache is greater than the first tilt angle only once, it controls the electric telescopic rod (306) to extend. If P is always less than the first pressure value during the extension process, the electric telescopic rod (306) retracts to the shortest; When the historical value a in the cache is greater than the first tilt angle twice, the controller (308) controls the electric telescopic rod (306) to extend. During the extension process, keep P always less than the second pressure value until the tilt angle is less than the second tilt angle and then the historical value a in the cache is greater than the first tilt angle three times, then the controller (308) controls the electric telescopic rod (306) to retract to the shortest and clears the cache.
