Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of barrier gates, and particularly relates to a servo direct-drive barrier gate movement and a barrier gate. Background Art
[0002] A barrier gate, also known as a vehicle stopper, is a channel access management device specifically used to restrict the driving of motor vehicles on roads. It is now widely used in highway toll stations and parking lot systems to manage vehicle channels for vehicle access.
[0003] Among them, the barrier gate includes a barrier gate housing and a barrier rod installed on the barrier gate housing. The barrier gate movement inside the barrier gate housing is used to drive the barrier rod to rotate, thereby realizing the lifting and lowering of the barrier rod. The traditional barrier gate uses an ordinary motor configured with a speed reducer as the driving source. During the speed reduction process of the speed reducer, there will be relatively large energy loss, resulting in low output efficiency of the ordinary motor and reducing the power output efficiency of the ordinary motor. Moreover, in order to improve the service life of the barrier gate, a tension spring is usually set between the barrier gate movement and the barrier rod to limit the position of the barrier rod for lifting and lowering through rotation, so that the barrier rod will not swing excessively and hit the ground. However, the setting of the tension spring increases the size of the movement in the vertical direction, which is not conducive to the miniaturization of the barrier gate movement.

[0011] In some embodiments, the first limiting member is provided with a first limiting screw and a second limiting screw, and the first limiting screw and the second limiting screw are arranged at a 90 degree interval along the circumference of the first limiting member;
[0012] Wherein, when the gate rod is in a vertical state, the first limit screw is abutted against the mounting plate; when the gate rod is in a horizontal state, the second limit screw is abutted against the mounting plate.
[0013] In some embodiments, the servo direct-drive barrier gate movement also includes a second limiting member, which is arranged on the first surface to abut the first limiting screw and / or the second limiting screw.

[0015] The first buffer is used to abut against the first limiting screw when the rotating shaft drives the first limiting member to rotate to a vertical state, and the second buffer is used to abut against the second limiting screw when the rotating shaft drives the first limiting member to a horizontal state.
[0016] In some embodiments, the first limiting member includes a sleeve portion and a first mounting arm and a second mounting arm radially extending from the sleeve portion, the sleeve portion is sleeved on the rotating shaft, and the first mounting arm and the second mounting arm are perpendicular to each other;
[0017] Among them, the first limit screw is arranged at one end of the first mounting arm away from the sleeve portion, and a first limit nut is sleeved on the first limit screw, and the first limit nut is used to limit the first limit screw from being separated from the first mounting arm; one end of the second limit screw is arranged at one end of the second mounting arm away from the sleeve portion, and a second limit nut is sleeved on the second limit screw, and the second limit nut is used to limit the second limit screw from being separated from the second mounting arm.
[0018] In some embodiments, the transmission assembly includes:

[0035] An embodiment of the present utility model provides a servo direct-drive barrier machine core. Referring to Figure 1 , it includes: a mounting plate 110, two mounting seats 120, a rotating shaft 130, and a driving mechanism 140. Among them, the mounting plate 110 is mainly used to fixedly mount components such as the mounting seats 120, the rotating shaft 130, and the driving mechanism 140. The mounting plate 110 is in a quadrilateral plate-like structure and has a first surface 111 and a second surface 112 that are oppositely arranged. The two mounting seats 120 are spaced apart and arranged on the first surface 111 of the mounting plate 110. Optionally, the mounting plate 110 can also be in a triangular or polygonal plate-like structure.
[0036] The rotating shaft 130 is rotatably connected to the two mounting seats 120, and one end of the rotating shaft 130 is used to connect to the gate rod 300 to drive the gate rod 300 to rotate. Among them, mounting holes are provided on the mounting seats 120, and the rotating shaft 130 is mounted on the mounting seats 120 through the mounting holes. Specifically, one end of the rotating shaft 130 extends out of the end of one of the mounting seats 120 to facilitate the connection with the gate rod 300; the other end of the rotating shaft 130 is flush with the end of the other mounting seat 120 to shorten the shaft length of the rotating shaft 130. After shortening the shaft length of the rotating shaft 130, the installation space when the servo direct-drive gate machine core 100 is installed in the gate machine case 200 can be saved, thereby reducing the volume of the gate machine case 200 and lowering the processing cost.
[0037] The driving mechanism 140 includes a direct-drive motor 141 and a transmission component 142. The direct-drive motor 141 is arranged on the second surface 112 of the mounting plate 110. The direct-drive motor 141 is in transmission connection with the rotating shaft 130 through the transmission component 142 to drive the rotating shaft 130 to rotate so as to drive the gate rod 300 to rotate. Among them, the main function of the direct-drive motor 141 is to provide the power for the rotation of the gate rod 300. In this embodiment, the direct-drive motor 141 is a servo direct-drive motor, and this servo direct-drive motor can directly serve as the drive source of the servo direct-drive gate machine core 100 without the need to configure a speed reducer, reducing the energy loss during the speed reduction process of the speed reducer and improving the power output efficiency of the direct-drive motor. Specifically, when the direct-drive motor 141 operates, the output shaft of the direct-drive motor 141 rotates to drive the transmission component 142 to transmit, thereby driving the rotating shaft 130 to rotate. Since the gate rod 300 is fixedly connected to the rotating shaft 130, the rotation of the rotating shaft 130 will drive the gate rod 300 to rotate to realize the vehicle management at the road entrance and exit. Among them, the clockwise rotation of the output shaft of the direct-drive motor 141 corresponds to the opening or closing of the gate rod 300, and the counterclockwise rotation of the output shaft of the direct-drive motor 141 corresponds to the closing or opening of the gate rod 300. Specifically, opening the gate means the state when the gate rod 300 rotates to the vertical position under the drive of the direct-drive motor 141, and closing the gate means the state when the gate rod 300 rotates to the horizontal position under the drive of the direct-drive motor 141; the transmission component 142 can be replaced by a gear transmission component, a belt pulley transmission component or a sprocket transmission component, including but not limited to this.
[0038] The first limiting member 150 is sleeved and fixed on the rotating shaft 130 and can rotate with the rotating shaft 130. The first limiting member 150 abuts against the mounting plate 110 to limit the rotation position of the gate rod 300. Among them, the first limiting member 150 is an integrally formed limiting block, and the limiting block can be triangular or fan-shaped. As can be seen from the rotating shaft 130 described above, the rotation of the rotating shaft 130 driven by the direct drive motor 141 can drive the gate rod 300 to rotate, that is, the rotating shaft 130 can rotate when subjected to a certain external force, and conversely, the gate rod 300 can also drive the rotating shaft 130 to rotate when subjected to a certain external force. Specifically, when the direct drive motor 141 suddenly loses power and the gate rod 300 is not in the horizontal state or the vertical state, the gate rod 300 will rotate under the action of its own gravity, thereby driving the rotating shaft 130 to rotate, and the first limiting member 150 will also rotate with the rotation of the rotating shaft 130. When the first limiting member 150 rotates to the position where it abuts against the mounting plate 110, the gate rod 300 will no longer rotate. The setting of the first limiting member 150 prevents the gate rod 300 from rotating excessively and hitting the ground and being damaged, and extends the service life of the gate rod 300.
[0039] The servo direct drive gate machine core 100 provided by the present utility model uses the direct drive motor 141 as the direct drive source, replacing the traditional structure that uses a common motor configured with a speed reducer as the drive source, avoiding the problem of low output efficiency caused by speed reduction through the speed reducer, and improving the power output efficiency of the direct drive motor 141; moreover, a first limiting member 150 that can rotate with it is fixedly sleeved on the rotating shaft 130. When the direct drive motor 141 drives the rotating shaft 130 to rotate and thus the gate rod 300 rotates to the horizontal state or the vertical state, the first limiting member 150 can abut against the mounting plate 110. Even if the direct drive motor 141 drives the gate rod 300 to rotate to an inclined state and suddenly loses power, under the limiting action of the first limiting member 150, the gate rod 300 will not be damaged due to its own gravity hitting the ground. That is, by setting the first limiting member 150, the swing angle of the gate rod 300 can be restricted, reducing the size of the servo direct drive gate machine core 100 in the vertical direction, which is beneficial to the miniaturization of the servo direct drive gate machine core 100.
[0040] In some embodiments, the first limiting member 150 is provided with a first limiting screw 151 and a second limiting screw 152. The first limiting screw 151 and the second limiting screw 152 are arranged at an interval of 90 degrees along the circumferential direction of the first limiting member 150. When the gate rod 300 is in a vertical state, the first limiting screw 151 abuts against the mounting plate 110. When the gate rod 300 is in a horizontal state, the second limiting screw 152 abuts against the mounting plate 110. The first limiting member 150 rotates with the rotation of the rotating shaft 130. When the first limiting screw 151 rotates to the position where it abuts against the mounting plate 110, the gate rod 300 is in a vertical state, that is, the gate rod 300 is in the open gate state. In this embodiment, the first limiting screw 151 and the second limiting screw 152 are arranged at an interval of 90 degrees along the circumferential direction of the first limiting member 150. That is, when the second limiting screw 152 abuts against the mounting plate 110, the gate rod 300 just rotates 90 degrees. At this time, the gate rod 300 is in a horizontal state, that is, the gate rod 300 is in the closed gate state. That is to say, by limiting the interval angle between the first limiting screw 151 and the second limiting screw 152 along the circumferential direction of the first limiting member 150, the rotation angle of the gate rod 300 can be controlled. Optionally, the first limiting screw 151 and the first limiting screw 151 can be replaced by a limiting post or a limiting pin, including but not limited to this.
[0041] In some embodiments, the servo direct drive gate machine core 100 further includes a second limiting member 160. The second limiting member 160 is arranged on the first surface 111 to be used for abutting against the first limiting screw 151 and / or the second limiting screw 152. When the second limiting member 160 is located on one side of the rotating shaft 130, optionally, the second limiting member 160 is used for abutting against the first limiting screw; or the second limiting member 160 is used for abutting against the second limiting screw. When the second limiting member 160 extends from one side of the rotating shaft 130 to the other side along the direction perpendicular to the rotating shaft 130, the second limiting member 160 is used for simultaneously abutting against the first limiting screw 151 and the second limiting screw 152. Specifically, when the gate rod 300 rotates to the open gate state or the closed gate state, the first limiting screw 151 and / or the second limiting screw 152 will abut against the second limiting member 160, rather than directly abutting against the mounting plate 110. In this case, the risk of damage to the mounting plate 110 caused by being repeatedly hit by the first limiting screw 151 and / or the second limiting screw 152 can be reduced.
[0042] In some embodiments, the second limiting member 160 includes a first buffer member 161 and a second buffer member 162. The first buffer member 161 and the second buffer member 162 are spaced apart on both sides of the extending direction of the rotating shaft 130. Wherein, the first buffer member 161 is used to abut against the first limiting screw 151 when the rotating shaft 130 drives the first limiting member 150 to rotate to the vertical state, and the second buffer member 162 is used to abut against the second limiting screw 152 when the rotating shaft 130 drives the first limiting member 150 to the horizontal state. Wherein, during the rotation of the first limiting member 150, the first limiting screw 151 and the second limiting screw 152 on the first limiting member 150 will collide with the mounting plate 110. After the first buffer member 161 and the second buffer member 162 are arranged on the mounting plate 110, the first limiting screw 151 and the second limiting screw 152 respectively impact on the first buffer member 161 and the second buffer member 162, which can buffer the collision between the first limiting screw 151 and the second limiting screw 152 and the mounting plate 110, reduce the collision force between the first limiting screw 151 and the second limiting screw 152 and the mounting plate 110, and avoid damage to the mounting plate 110. Wherein, the first buffer member 161 and the second buffer member 162 are buffer pads or buffer columns. Optionally, the buffer pads or buffer columns are made of silica gel, or the buffer pads or buffer columns are made of urethane rubber.
[0043] Referring to Figure 2 , in some embodiments, the first limiting member 150 includes a sleeved portion 153, a first mounting arm 154 and a second mounting arm 155 radially extending from the sleeved portion 153. The sleeved portion 153 is sleeved on the rotating shaft 130, and the first mounting arm 154 and the second mounting arm 155 are perpendicular to each other. Wherein, one end of the first limiting screw 151 is arranged at the end of the first mounting arm 154 far from the sleeved portion 153, and a first limiting nut 156 is sleeved on the first limiting screw 151. The first limiting nut 156 is used to limit the first limiting screw 151 from detaching from the first mounting arm 154. The second limiting screw 152 is arranged at the end of the second mounting arm 155 far from the sleeved portion 153, and a second limiting nut 157 is sleeved on the second limiting screw 152. The second limiting nut 157 is used to limit the second limiting screw 152 from detaching from the second mounting arm 155. Wherein, a first threaded hole is provided on the first mounting arm 154, and the first limiting screw 151 is threadedly connected to the first mounting arm 154 through the first threaded hole. After the first limiting screw 151 passes through the first threaded hole, the first limiting nut 156 is sleeved, so that the installation of the first limiting screw 151 is more firm. A second threaded hole is provided on the second mounting arm 155, and the second limiting screw 152 is threadedly connected to the second mounting arm 155 through the second threaded hole. After the second limiting screw 152 passes through the second threaded hole, the second limiting nut 157 is sleeved, so that the installation of the second limiting screw 152 is more firm and the disassembly is also relatively convenient.
[0044] In some embodiments, the transmission assembly 142 includes: a driving swing arm 1421, one end of the driving swing arm 1421 is fixedly connected to the output shaft of the direct drive motor 141; a driven swing arm 1422, one end of the driven swing arm 1422 is fixedly connected to the rotating shaft 130; a connecting rod 1423, one end of the connecting rod 1423 is drivingly connected to the other end of the driving swing arm 1421, and the other end of the connecting rod 1423 is drivingly connected to the other end of the driven swing arm 1422. Wherein, after the direct drive motor 141 rotates, it drives the driving swing arm 1421 to swing. After the driving swing arm 1421 swings, it drives the connecting rod 1423 to swing. After the connecting rod 1423 swings, it drives the driven swing arm 1422 to swing. After the driven swing arm 1422 swings, it drives the rotating shaft 130 to rotate clockwise or counterclockwise, thereby driving the gate rod 300 to rotate to realize vehicle management at the road entrance and exit. In this embodiment, by connecting the driving swing arm 1421 and the driven swing arm 1422 through the connecting rod 1423, a limiting function can be realized, that is, under the connection of the connecting rod 1423, the driven swing arm 1422 will not swing excessively, and the limit points of the swing of the driven swing arm 1422 respectively correspond to the opening or closing of the gate rod 300.
[0045] In some embodiments, the servo direct drive gate machine core 100 further includes a locking collar 170. The locking collar 170 is arranged on the rotating shaft 130 and connected to the driven swing arm 1422 to limit the driven swing arm 1422 from shifting towards the end close to the gate rod 300. Wherein, the locking collar 170 is sleeved on the rotating shaft 130 and fixedly connected to the driven swing arm 1422. When the direct drive motor 141 operates, it will drive the driving swing arm 1421 in the transmission assembly 142 to rotate. After the driving swing arm 1421 rotates, it drives the connecting rod 1423 to rotate. After the connecting rod 1423 rotates, it drives the driven swing arm to rotate. Under the limitation of the locking collar 170, the driven swing arm 1422 will not get stuck due to shifting, so that the connecting rod 1423 can smoothly drive the driven swing arm 1422 to rotate, ensuring the normal operation of the servo direct drive gate machine core 100.
[0046] In some embodiments, the servo direct drive gate machine core 100 further includes a gate rod clamping plate 180. The gate rod clamping plate 180 is connected to the rotating shaft 130 for installing the gate rod 300. Wherein, a groove is provided on the gate rod clamping plate 180, and the shape of the groove is adapted to the gate rod 300. One end of the gate rod 300 is inserted into the groove of the gate rod clamping plate 180 and then installed on the gate rod clamping plate 180. Optionally, when the gate rod 300 is rectangular, the groove of the gate rod clamping plate 180 is a rectangular groove; or when the gate rod 300 is circular, the groove of the gate rod clamping plate 180 is an arc-shaped groove. Further, in this embodiment, the gate rod 300 is detachably installed on the gate rod clamping plate 180 by screws. When the gate rod 300 is damaged due to long-term use or collision, the gate rod 300 can be directly detached from the gate rod clamping plate 180 for replacement, and the operation is simple and convenient.
[0047] In some embodiments, the mounting plate 110 is provided with an avoidance hole 113, and the avoidance hole 113 is arranged corresponding to the transmission assembly 142, so that the transmission assembly 142 passes through the avoidance hole 113. Among them, the direct drive motor 141 is in transmission connection with the rotating shaft 130 through the transmission assembly 142, and the transmission assembly 142 is placed in the avoidance hole 113, making the overall structure of the servo direct drive gate machine core 100 compact, capable of saving the installation space when the servo direct drive gate machine core 100 is installed in the gate machine box 200 subsequently, thereby reducing the volume of the gate machine box 200 and lowering the processing cost.
[0048] Referring to Figure 3 , an embodiment of the present invention further provides a gate 1000, which includes a gate machine box 200 and the servo direct drive gate machine core 100 described in the foregoing embodiments, and the servo direct drive gate machine core 100 is arranged inside the gate machine box 200. Since this gate 1000 adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the technical effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated herein one by one.
