Description

Technical Field

[0001] The present invention relates to the technical field of lodging mechanisms, and in particular to a lodging mechanism. Background Art

[0002] When using a lifting pole, a retracting mechanism is often used in conjunction with the lifting pole. The lifting pole is installed on the vehicle to lift equipment that needs to be elevated, such as antennas, cameras, and lighting. When the equipment on the top of the lifting pole is taller or longer (such as a whip antenna, etc.), and in order not to affect the vehicle's passability in narrow spaces such as tunnels, it is often necessary to add a retracting mechanism between the top of the lifting pole and the equipment; when the vehicle is parked, the lifting pole is unfolded, and the retracting mechanism erects the equipment so that the equipment can be used normally; when driving, the lifting pole is closed, and the retracting mechanism retracts the equipment at an angle of 90°, 180°, etc., to reduce the net height so as not to affect the vehicle's passability.

[0003] At present, the lodging mechanisms used in conjunction with lifting rods in the industry mainly include electric lodging mechanisms and mechanical lodging mechanisms driven by gear racks.

[0004] The following problems exist when using the electric lodging mechanism:

[0005] If this application Figure 1-3 As shown, the electric lodging mechanism b is driven by a motor, which realizes the lodging of the device c through the transmission of a worm gear or other reduction structure. Since the electric lodging mechanism b contains a motor, an electrical control and drive module, a limit switch, etc., the cost is relatively high and the structure is complex, which reduces the reliability of the system. Figure 3 As shown, the electric lodging mechanism b requires cable b1 to complete the drive and control of the motor, which increases the cost. The existence of cable b1 in the electric lodging mechanism increases the difficulty of handling cable c1 on the device c. For example, the device c has only one cable. After adding the electric lodging mechanism b, the total number of cables is two. If manual retraction and release is used, the workload of the operators is increased. If automatic retraction and release is used, a more complex retraction device is required.

[0006] The following problems exist when using the mechanical lodging structure driven by a gear rack:

[0007] like Figure 4As shown, when the lifting rod a is retracted, the mechanical lodging mechanism d relies on the pushing force of the rack push plate d1 on the other pipe sections of the lifting rod a to the rack d2 to drive the mechanical lodging mechanism d into a horizontal state, and at the same time, the internal spring stores energy. When the lifting rod a is unfolded, the mechanical lodging mechanism d and the rack d2 are reset by the spring elastic force, and the mechanical lodging mechanism d enters a vertical state. When the mechanical lodging mechanism d is working, it needs to contact or separate with the associated pipe section, which will generate impact, and the working section of the mechanical lodging mechanism d is the rack motion section, which is only a part of the pipe section motion stroke. The mechanical lodging mechanism d has a short working time and needs to withstand a large power or torque, so it requires a higher structural strength. Summary of the invention

Moreover, the mechanical lodging mechanism needs to contact and separate from the associated pipe segment when working, which will produce impact. Therefore, the lodging mechanism of the present application has a longer working time, needs to withstand less power or torque, and has lower structural strength requirements, which is a significant improvement.

DETAILED DESCRIPTION

[0048] See also Figure 5-17 , further illustrate the embodiments of the present invention;

[0049] like Figure 5 , 8As shown in Figure 12, a lodging mechanism comprises: a casing 1, a worm gear assembly 2, a reel 4, a transmission assembly 3, and a scroll spring member 6; the worm gear assembly 2 is installed in the casing 1, and one end of the worm gear assembly 2 passes through the outside of the casing 1; a mounting frame 13 is provided on the casing 1, the mounting frame 13 is fixedly connected to the worm gear assembly 2, and a device c is bolted to the side of the mounting frame 13, a lifting rod a is installed at the lower end of the casing 1, and a fixing frame 7 is installed at the pipe joint of the lifting rod a; the reel 4 is rotatably connected to one side of the casing 1, and the reel 4 is sleeved and transmission-connected to the outer end of the worm gear assembly 2, a traction rope 5 is wound around the outside of the reel 4, and the lower end of the traction rope 5 is tied to the fixed On the fixed frame 7; the transmission component 3 is installed in the casing 1 and is transmission-connected with the inner end of the worm gear component 2, and one end of the transmission component 3 passes through the outside of the casing 1; the spiral spring component 6 is installed on the other side of the casing 1, and the spiral spring component 6 is transmission-connected with the outer end of the transmission component 3; when in use, the lifting rod a can be installed on the vehicle so that the lifting rod a and the lodging mechanism can be moved to the required position, the lifting rod a is used to fix and lift the lodging mechanism, and the lodging mechanism is used to lodging equipment c, and equipment c includes antennas, cameras, lighting lamps and other equipment that need to be elevated; in the initial state, the lifting rod a is in a retracted state, and the lodging mechanism and equipment c are both in a horizontal state.

[0050] When the lifting rod a is unfolded, the fixing frame 7 at the pipe joint of the lifting rod a will pull the traction rope 5 out of the drum 4, which can drive the drum 4 to rotate, and the drum 4 will drive the worm gear assembly 2, and the worm gear assembly 2 will drive the mounting frame 13 and the device c to rotate until the device c rotates to the working position, that is, the device c rotates from the horizontal state to the vertical state, and at the same time, the worm gear assembly 2 drives the transmission assembly 3 to store energy for the scroll spring member 6.

[0051] When the lifting rod a contracts, the energy-storing scroll spring member 6 drives the transmission assembly 3 and the worm gear assembly 2 to reverse, thereby rotating the mounting frame 13 and the device c to the initial state. At the same time, the worm gear assembly 2 drives the reel 4 to rotate in the opposite direction, and the traction rope 5 is rewound on the reel 4.

[0052] Compared with the electric lodging mechanism b, the present invention can not only realize the lodging function, but also has a purely mechanical structure without electrical components and has higher reliability. In addition, the present invention uses the relative movement between the tubes in the lifting rod a as the working power, does not require cables, reduces costs and reduces the difficulty of retracting and releasing the cables in the top device c of the lifting rod a;

[0053] Compared with the mechanical lodging mechanism d, the present application has a continuous and stable operation during the movement of the entire pipe segment in the lifting rod a, without disengagement and separation, that is, the entire working process of the pipe segment associated with the lifting rod a from the start of movement to the stop of movement of the pipe segment is the entire journey of the pipe segment, while the working section of the mechanical lodging mechanism d is the rack movement section, which is only a part of the movement stroke of the pipe segment, and the mechanical lodging mechanism d needs to contact and separate with the associated pipe segment when working, which will produce impact. Therefore, the lodging mechanism of the present application has a longer working time, needs to withstand less power or torque, and has lower structural strength requirements, which is a significant improvement;

[0054] like Figure 8 As shown, the worm gear assembly 2 includes a worm 21, a worm wheel 22 and a worm wheel shaft 23. The worm wheel 22 is sleeved and fixed on the worm wheel shaft 23. The worm 21 and the worm wheel shaft 23 are both rotatably connected in the casing 1, and the worm 21 is transmission-connected with the worm wheel 22. The outer end of the worm 21 penetrates the casing 1 and extends into the reel 4 and is transmission-connected with the reel 4, and the inner end of the worm 21 is transmission-connected with the transmission assembly 3, and the two ends of the mounting frame 13 are fixedly connected to the two ends of the worm wheel shaft 23 respectively.

[0055] like Fig.10 As shown, gear 1 212 is sleeved and fixed at both inner and outer ends of the worm 21; a circle of tooth grooves is provided on the inner side of the reel 4, and the external gear 1 212 is meshed and connected with the tooth grooves; the transmission assembly 3 includes a gear shaft 31 and a gear 2 32, the gear shaft 31 is rotatably connected in the housing 1, and the gear shaft 31 is connected to the scroll spring member 6, the gear 2 32 is sleeved and fixed on the gear shaft 31, and the gear 2 32 is meshed and connected with the internal gear 1 212; the transmission ratios of gear 1 212 and gear 2 32, and gear 1 212 and the tooth grooves are both 1:1, and the transmission ratios of the worm 21 and the worm wheel 22 are both 20:1; the length range of the traction rope 5 is [1.2m, 1.5m].

[0056] like Figure 8 As shown, in order to ensure the stable operation of the worm 21, the worm wheel 22 and the worm wheel shaft 23, a limiting flange 211 is flange-connected to the outer end of the worm 21, the limiting flange 211 is bolted to the casing 1, both ends of the worm wheel shaft 23 are flange-connected to limiting flange 231, the limiting flange 231 is bolted to the casing 1, and a limiting sleeve 221 for limiting the worm wheel 22 is sleeved on the worm wheel shaft 23.

[0057] like Figure 8 , 10 As shown in FIG. 11 , the spiral spring member 6 includes a spring box 61 and a spiral spring 62 . The spring box 61 is fixed to the outer wall of the casing 1 , and the spiral spring 62 is installed in the spring box 61 . The outer end of the gear shaft 31 extends into the spring box 61 and is fixedly connected to the spiral spring 62 .

[0058] like Figure 5 and 8As shown, the upper and lower sides of the casing 1 and the side close to the scroll spring member 6 are all open ends, and the three open ends of the upper side, the lower side and the side are detachably connected (such as bolt connection, snap connection, etc.) with an upper end cover 11, a lower end cover 12 and a side cover 14, and the scroll spring member 6 is detachably connected (such as bolt connection, snap connection, etc.) to the side cover 14, and an axial hole is opened on the side cover 14, and the outer end of the gear shaft 31 is rotatably connected to the axial hole; the upper end cover 11 and the lower end cover 12 are respectively used to close the open ends of the upper and lower sides of the casing 1, and the side cover 14 is used to close the open ends of the side of the casing 1 and serve as a mounting structure for the scroll spring member 6. The arrangement of the upper end cover 11, the lower end cover 12 and the side cover 14 facilitates the staff to install multiple components in the casing 1.

[0059] Here’s how this application works:

[0060] When in use, the lifting rod a is installed on the vehicle so that the lifting rod a and the lodging mechanism can be moved to the desired position. The lifting rod a is used to fix and lift the lodging mechanism, and the lodging mechanism is used to lodging the device c. In the initial state, the lifting rod a is in a retracted state, and the lodging mechanism and the device c are both in a horizontal state. Fig.12 .

[0061] When the device c needs to be lifted after parking, the lifting rod a is unfolded, and the fixing frame 7 at the pipe joint of the lifting rod a will pull the traction rope 5 out of the drum 4, which can drive the drum 4 to rotate, and the drum 4 will drive the worm 21 to rotate, and the worm 21 drives the worm wheel 22 and the worm wheel shaft 23 to rotate, thereby driving the mounting frame 13 and the device c to rotate to the working position of the device c, and the worm wheel assembly 2 will drive the mounting frame 13 and the device c to rotate until the device c rotates to the working position, that is, from the horizontal state of the device c to the vertical state. During the rotation of the worm 21, the two gears 1 212 thereon will be driven to rotate, and one of the gears 1 212 will drive the gear 2 32 to drive the gear shaft 31 to rotate, and the gear shaft 31 will drive the volute spring 62 in the spring box 61 to wind up and store energy.

[0062] When the device c needs to be folded before driving, the lifting rod a is retracted first, and the spiral spring member 6 that has been wound up and stored energy drives the worm 21 to rotate in the opposite direction through the gear shaft 31, the second gear 32, and the first gear 212, and the worm 21 drives the worm wheel 22 and the worm wheel shaft 23 to rotate in the opposite direction, so that the mounting frame 13 and the device c rotate to the initial state. When the worm 21 rotates, it drives the drum 4 to rotate in the opposite direction, so that the pulled traction rope 5 is rewound on the drum 4.

[0063] It should be noted that during the working process, the present application uses the separation movement between the lifting rod a and the tube as the power, and drives the reel 4 to rotate through the traction rope 5 to drive the lodging mechanism to work;

[0064] Generally, when the device C only uses the self-locking effect of the worm 21 and the worm wheel 22 for braking, after a long period of use, the gap between the worm 21 and the worm wheel 22 becomes larger, and the device C shakes significantly. In order to avoid this adverse effect, a braking device is usually required. However, since the present application is provided with a volute spring 62, when in use, the volute spring 62 performs a deceleration transmission on the worm wheel assembly 2, and has sufficient pre-tightening torque, and the random shaking of the device C can be avoided without adding a braking device;

[0065] like Fig.12 As shown, the relevant pipe segments on the lifting rod a work continuously and stably throughout the entire movement process without falling out or separating, and no impact occurs during operation. Compared with the mechanical lodging mechanism d, the same structural strength can withstand greater power or torque;

[0066] like Fig.13 As shown, the traction rope 5 is wound on the drum 4 in a spiral manner, and the traction belt 51 can also be wound on the drum 4 in a stacked manner;

[0067] like Fig.14 As shown, in order to save space, the volute spring 62 in the example is connected to the worm 21 through the gear shaft 31 and the gear 2 32. In an application scenario with sufficient space, the volute spring 62 can be directly installed on the worm 21 for driving;

[0068] This application can be used not only on lifting rod a, but also on other similar telescopic structures;

[0069] In the example, after the spiral spring 62 has completed the energy storage, when the inverting mechanism is required to work in the reverse direction, the spiral spring 62 drives the worm 21 through the gear shaft 31 and the gear 2 32, and the worm 21 drives the worm wheel 22 and the worm wheel shaft 23 to work in the reverse direction. In addition to this design, Fig.15 and 16 As shown, the volute spring 62 can also be directly connected to the worm gear shaft 23. After the volute spring is fully charged, when the lodging mechanism is required to work in the reverse direction, the volute spring 62 directly drives the worm gear shaft 23 to work in the reverse direction, and drives the reel 4 to wind the traction rope 5 through the worm gear 22 and the worm 21. This structure requires that the transmission structure of the worm 21 and the worm gear 22 has no self-locking property.

[0070] In the example, the transmission mode between the spiral spring 62 and the worm 21 is gear transmission. In the application, other transmission modes such as chain transmission and belt transmission can also be used as long as they can be realized.

[0071] When the scroll spring 62 drives the device c to rotate back to the initial position (the specific operation is not repeated), the device c is limited by the traction rope 5: when the lifting rod a is fully retracted, the traction rope 5 is straightened under the action of the scroll spring 62 driving the reel 4, limiting the rotation of the reel 4, thereby limiting the device c from continuing to rotate and completing the limit. If necessary, a mechanical limit structure can be designed separately, such as Fig.17 In the embodiment, limiting steps 8 are fixed at the lower sides of the casing 1 , and the limiting steps 8 are used for limiting the mounting frame 13 .

[0072] Specific examples are as follows:

[0073] like Figure 7 , 9 As shown in 10 and 11, the falling angle of the device c is 90°, the transmission ratios of the gear 1 212 and the gear 2 32, and the gear 1 212 and the tooth groove are both 1:1, and the transmission ratios of the worm 21 and the worm wheel 22 are both 20:1; the maximum working length of the traction rope 5 driven by the rope end fixing frame 7 on the lifting rod a is 1 meter.

[0074] Since the device c has a lodging working angle of 90°, that is, the number of turns is 0.25, the number of turns of the worm wheel 22 is 0.25, and the number of turns of the worm 21 is 5, the diameter of the drum 4 is designed to ensure that the drum 4 rotates 5 times when the traction rope 5 reaches a working length of 1 meter. Since the transmission ratio between gears is 1:1, the number of working turns of the volute spring 62 is designed to be 5, which can meet the requirements.

[0075] The falling mechanism changes from vertical to horizontal state: when the lifting rod a is retracted, if at a certain moment the fixed frame 7 (at the lower end of the traction rope 5) moves 1 / n meter in the retraction direction, its working stroke is 1 / n of its maximum working length. At this moment, the volute spring 62 drives the worm 21 and the drum 4 to wind up all the "redundant" traction ropes 5 on the drum 4. The specific operation is not repeated here. The number of turns of the volute spring 62 is 5 / n. The number of turns of the worm wheel 22, the worm wheel shaft 23 and the device c is (5 / n)÷20=1 / (4n) turns, that is, 1 / n of 0.25 turns. That is, at any moment, the fixed frame 7 moves 1 / n in the contraction direction, the falling angle of the falling mechanism from the vertical to the horizontal state is 1 / n of its total working angle, and the number of turns driven by the spiral spring 62 to wind up the reel 4 is 1 / n of its maximum working turns (5 turns in this case), ensuring the synchronization and unity of the ratio of the number of turns driven by the spiral spring 62 to wind the traction rope 5 to the maximum working number of turns, the ratio of the wound length of the traction rope 5 to the maximum working length, the ratio of the working turns of the spiral spring 62 to the maximum working number of turns, and the ratio of the rotation angle of the equipment c to the maximum working angle during the whole process.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
