Description

Technical Field

[0001] This application relates to the technical field of barrier gate devices, and particularly to a barrier gate core and a barrier gate. Background Art

[0002] A barrier gate, also known as a vehicle stopper, can be lifted and lowered under the control of a wireless remote control device or a parking lot management system. It is a channel access management device specifically used to restrict the driving of motor vehicles on roads and is now widely used in vehicle channels such as highway toll stations and parking lot system management to manage the entry and exit of vehicles.

[0003] The length of the barrier rod is much greater than the diameter of the barrier gate core. The barrier gate needs to output a relatively large torque to drive the barrier rod. This requires a corresponding sensing device to provide a feedback sensing signal to the driving device after the barrier rod falls or is lifted to the in-place position. After receiving this feedback sensing signal, the driving device stops working to avoid damage to the barrier gate core. Since in most cases, the barrier gate is set in an outdoor environment, for traditional barrier gate cores, the sun exposure plus the heat generated by the driving device and control circuit of the barrier gate itself will cause a significant increase in the temperature of the barrier gate, affecting the normal operation of the sensing device and even causing the sensing device to malfunction.

[0029] In order to illustrate the technical solution described in the present application, the following will be described in detail with reference to specific drawings and embodiments.

[0030] Please refer to Figure 2 、 Figure 5 and Figure 6 As shown in

[0031] Please refer to Figure 1 and Figure 2, as a specific solution of this embodiment, the support assembly 1 may include a support plate 11 and a main board 12 disposed opposite to the support plate 11. The core shaft 2 is hinged to the support plate 11, the driver 3 is connected to the support plate 11, and the barrier gate core further includes a transmission assembly 7 connected to the support plate 11. The driver 3 can drive the core shaft 2 to rotate through the transmission assembly 7 to realize the switching of the core shaft 2 between the first state and the second state, thereby controlling the raising and lowering of the barrier rod 9; the support plate 11 is made of a metal plate, preferably an aluminum-based metal plate, to ensure sufficient mechanical strength, and the aluminum-based metal plate is not ferromagnetic. When the first sensing element 5 and the second sensing element 6 respectively adopt a Hall sensor and a magnetic part, it will not affect the operation of the first sensing element 5 and the second sensing element 6. The first sensing element 5 is attached to the main board 12, and the temperature compensation assembly 4 is disposed on the side of the main board 12 where the first sensing element 5 is attached; the main board 12 is a PCB board (Printed Circuit Board), and corresponding control and measurement circuits are printed on the PCB board for receiving the first sensing signals sent by the first sensing element 5 and the second sensing element 6, and controlling the operation of the driver 3 according to the first sensing signals and preset logic.

[0032] Specifically, the barrier gate core provided in this embodiment works as follows:

[0033] Please refer to Figures 1 to 3 , Figure 5 and Figure 6 , the support assembly 1 provides support for the core shaft 2, the driver 3 and the transmission assembly 7. The barrier rod 9 is connected to one end of the core shaft 2, and the barrier rod 9 rotates with the rotation of the core shaft 2. The driver 3 is connected to the core shaft 2 through the transmission assembly 7. The power output by the driver 3 is transmitted through the transmission assembly 7 and finally becomes the rotational torque of the core shaft 2, driving the barrier rod 9 to rise or controlling the barrier rod 9 to fall. The driver 3 can drive the core shaft 2 to switch between the first state and the second state through the transmission assembly 7. When the core shaft 2 rotates clockwise to the first state, the first sensing element 5 and the second sensing element 6 cooperate to sense that the core shaft 2 rotates in place and generate a first sensing signal, and further control the driver 3 to stop working according to the first sensing signal. When the temperature of the barrier gate core rises due to sunlight irradiation or internal heating, the temperature compensation assembly 4 can compensate for the decrease in the sensitivity of the first sensing element 5 and the second sensing element 6.

[0034] Implementing the barrier gate core provided in this embodiment has at least the following beneficial technical effects:

[0035] The barrier gate mechanism provided in this embodiment is provided with a first sensing element 5 and a second sensing element 6 for sensing the rotation state of the core shaft 2. When the core shaft 2 rotates to the first state, a first sensing signal can be generated, and then the drive 3 can be controlled to stop working according to the first sensing signal, avoiding damage to the mechanical structure of the barrier gate mechanism caused by the continuous rotation of the drive 3 after rotating in place; by providing a temperature compensation component 4, when the temperature of the barrier gate mechanism rises due to sunlight irradiation or internal heating, the decrease in the sensitivity of the first sensing element 5 and the second sensing element 6 can be compensated, thereby avoiding the influence of the temperature rise of the barrier gate mechanism on the normal operation of the first sensing element 5 and the second sensing element 6. The first sensing element 5 and the second sensing element 6 can stably send the first sensing signal when the core shaft 2 rotates to the first state, avoiding the continuous operation of the drive 3 after the core shaft 2 rotates to the first state.

[0036] Please refer to Figures 4 to 6 , in an embodiment of the present application, the temperature compensation component 4 includes a first temperature compensation rod 41 that can rotate synchronously with the core shaft 2. The first sensing element 5 includes a first Hall sensor 51, and the second sensing element 6 includes a first magnetic member 61 connected to the first temperature compensation rod 41. The first magnetic member 61 can rotate to a position opposite to the first Hall sensor 51 with the first temperature compensation rod 41 when the core shaft 2 rotates to the first state; one end of the first temperature compensation rod 41 is connected to the core shaft 2, and the other end of the first temperature compensation rod 41 is connected to the first magnetic member 61. The first temperature compensation rod 41 can bend with the increase in temperature.

[0037] Please refer to Figures 3 to 6 , specifically, when the core shaft 2 rotates to the first state, the first magnetic member 61 is directly opposite to the first Hall sensor 51, and the first Hall sensor 51 generates a first Hall voltage as the magnetic field increases. This first Hall voltage is the first sensing signal; as the temperature rises, the magnetism of the first magnetic member 61 will relatively weaken, and the first Hall voltage generated by the first Hall sensor 51 when the core shaft 2 rotates to the first state will also decrease accordingly. At this time, since the first temperature compensation rod 41 can bend with the increase in temperature, the first temperature compensation rod 41 can be configured to bend the end provided with the first magnetic member 61 in the direction close to the first Hall sensor 51 at high temperature and when the core shaft 2 rotates to the first state. In this way, when the core shaft 2 rotates to the first state, the distance between the first magnetic member 61 and the first Hall sensor 51 decreases with the increase in temperature, thereby realizing the compensation for the demagnetization of the first magnetic member 61 when the temperature rises, and ensuring the sensing signal intensity of the first Hall voltage at any temperature.

[0038] Please refer to Figure 6, as a specific solution of this embodiment, one end of the first temperature compensation rod 41 connected to the mandrel 2 is provided with a first through hole 411 and a first arc-shaped groove 412 extending along an arc centered on the first through hole 411.

[0039] In this way, a first connecting member 81 extending into the first through hole 411 and connecting to the mandrel 2 and a second connecting member 82 extending into the first arc-shaped groove 412 and connecting to the mandrel 2 can be provided. The first connecting member 81 and the second connecting member 82 together fix the first temperature compensation rod 41 on the mandrel 2 and enable the first temperature compensation rod 41 and the mandrel 2 to rotate synchronously; when the orientation of the first temperature compensation rod 41 needs to be adjusted, only the first connecting member 81 and the second connecting member 82 need to be loosened slightly, and then the first temperature compensation rod 41 is rotated around the first connecting member 81. During this process, the second connecting member 82 slides along the first arc-shaped groove 412. The advantage of providing the first through hole 411 and the first arc-shaped groove 412 in the first temperature compensation rod 41 is that the first temperature compensation rod 41 can be rotated and refixed on the mandrel 2 without changing the connection positions of the first connecting member 81 and the second connecting member 82 with the mandrel 2, avoiding opening connection grooves or excessive connection holes for connection on the mandrel 2, ensuring the structural strength of the mandrel 2 and simplifying the structure of the mandrel 2.

[0040] Please refer to Figures 4 to 7 , in an embodiment of the present application, the first temperature compensation rod 41 includes a first expansion layer 413 and a second expansion layer 414 attached to the first expansion layer 413; the thermal expansion coefficient of the second expansion layer 414 is greater than that of the first expansion layer 413.

[0041] The first expansion layer 413 and the second expansion layer 414 are attached to each other, and the thermal expansion coefficient of the second expansion layer 414 is greater than that of the first expansion layer 413. When the first temperature compensation rod 41 is heated, the expansion ratio of the second thermal expansion layer is greater than that of the first expansion layer 413. In this way, since the first expansion layer 413 and the second expansion layer 414 are attached to each other and one end of the first temperature compensation rod 41 is connected to the mandrel 2, when the first temperature compensation rod 41 is heated, the thermal expansion effect of the first expansion layer 413 is stronger than that of the second expansion layer 414. One end of the first temperature compensation rod 41 connected to the first magnetic member 61 will bend in the direction where the second expansion layer 414 points to the first expansion layer 413, so that when the mandrel 2 rotates to the first state, the distance between the first magnetic member 61 and the first Hall sensor 51 is closer, thereby compensating for the weakening of the magnetism of the first magnetic member 61 at high temperatures.

[0042] As a specific solution of this embodiment, the first thermal expansion layer and the second thermal expansion layer are made of two materials with a large difference in thermal expansion coefficient and close elastic modulus, so that the first expansion layer 413 and the second expansion layer 414 can fit together better when the first temperature compensation rod 41 bends; more specifically, invar can be used as the material of the first expansion layer 413, and non-magnetic steel can be used as the material of the second expansion layer 414.

[0043] Please refer to Figure 7 , in an embodiment of the present application, the second expansion layer 414 is disposed on the side of the first expansion layer 413 away from the support assembly 1, the first magnetic member 61 is disposed on the side of the first expansion layer 413 opposite to the support assembly 1, and the first Hall sensor 51 is disposed on the side of the support assembly 1 opposite to the first temperature compensation rod 41; alternatively, a first boss (not shown in the figure) is provided on the side of the support assembly 1 opposite to the first temperature compensation rod 41, the first Hall sensor 51 is disposed on the side surface of the first boss, the second expansion layer 414 is disposed on the side of the first expansion layer 413 away from the first Hall sensor 51, and the first magnetic member 61 is disposed on the side of the first expansion layer 413 opposite to the first Hall sensor 51.

[0044] In an embodiment of the present application, the first sensing element 5 further includes a second Hall sensor 52, and the first magnetic member 61 can rotate to a position opposite to the second Hall sensor 52 along with the first temperature compensation rod 41 when the mandrel 2 rotates to the second state.

[0045] In this embodiment, when the mandrel 2 rotates to the second state, the first magnetic member 61 and the second Hall sensor 52 can cooperate with each other to generate a second Hall voltage, and this second Hall voltage is the second sensing signal; as the temperature rises, the magnetism of the first magnetic member 61 will relatively weaken, and the second Hall voltage generated by the second Hall sensor 52 when the mandrel 2 rotates to the second state will also decrease accordingly. At this time, since the first temperature compensation rod 41 can bend with the increase of temperature, the first temperature compensation rod 41 can be configured to bend the end provided with the first magnetic member 61 towards the direction close to the second Hall sensor 52 at high temperature and when the mandrel 2 rotates to the second state. In this way, when the mandrel 2 rotates to the second state, the distance between the first magnetic member 61 and the second Hall sensor 52 decreases with the increase of temperature, thereby realizing the compensation for the demagnetization of the first magnetic member 61 when the temperature rises and ensuring the sensing signal intensity of the second Hall voltage at any temperature.

[0046] Similarly feasible, please refer to Figures 3 to 6, in an embodiment of the present application, the temperature compensation component 4 further includes a second temperature compensation rod 42 capable of rotating synchronously with the mandrel 2, the first sensing element 5 further includes a second Hall sensor 52, and the second sensing element 6 further includes a second magnetic member 62 connected to the second temperature compensation rod 42. The second magnetic member 62 can rotate to a position opposite to the second Hall sensor 52 with the second temperature compensation rod 42 when the mandrel 2 rotates to the second state; one end of the second temperature compensation rod 42 is connected to the mandrel 2, the other end of the second temperature compensation rod 42 is connected to the second magnetic member 62, and the second temperature compensation rod 42 can bend with the increase in temperature.

[0047] In this embodiment, when the mandrel 2 rotates to the second state, the second magnetic member 62 and the second Hall sensor 52 can cooperate with each other to generate a second Hall voltage, and this second Hall voltage is the second sensing signal; as the temperature increases, the magnetism of the second magnetic member 62 will relatively weaken, and the second Hall voltage generated by the second Hall sensor 52 when the mandrel 2 rotates to the second state will also decrease accordingly. At this time, since the first temperature compensation rod 41 can bend with the increase in temperature, the first temperature compensation rod 41 can be configured to bend the end provided with the second magnetic member 62 towards the direction close to the second Hall sensor 52 at high temperature and when the mandrel 2 rotates to the second state. In this way, when the mandrel 2 rotates to the second state, the distance between the second magnetic member 62 and the second Hall sensor 52 decreases with the increase in temperature, thereby realizing the compensation for the demagnetization of the second magnetic member 62 when the temperature increases and ensuring the sensing signal strength of the second Hall voltage at any temperature.

[0048] In this embodiment, the structure, material, and working principle of the second temperature compensation rod 42 are the same as those of the first temperature compensation rod 41.

[0049] As a specific solution of this embodiment, the second temperature compensation rod 42 includes a third expansion layer and a fourth expansion layer attached to the third expansion layer; the thermal expansion coefficient of the fourth expansion layer is greater than that of the third expansion layer. The fourth expansion layer is attached to the side of the third expansion layer away from the support assembly 1, the second magnetic member 62 is attached to the side of the third expansion layer opposite to the support assembly 1, and the second Hall sensor 52 is attached to the side of the support assembly 1 opposite to the second temperature compensation rod 42; alternatively, a second boss (not shown in the figure) is provided on the side of the support assembly 1 opposite to the second temperature compensation rod 42, the second Hall sensor 52 is disposed on the side surface of the second boss, the fourth expansion layer is attached to the side of the third expansion layer away from the second Hall sensor 52, and the second magnetic member 62 is attached to the side of the third expansion layer opposite to the second Hall sensor 52.

[0050] In an embodiment of the present application, the first sensing element 5 further includes a plurality of third Hall sensors 53. The third Hall sensors 53 are arranged along the path that the first magnetic member 61 sweeps across the surface of the support assembly 1 during the rotation of the core shaft 2 from the first state to the second state.

[0051] The purpose of arranging the third Hall sensors 53 is to measure the rotational speed and rotational position of the core shaft 2 through the plurality of third Hall sensors 53. Furthermore, when it is found that the rotational speed of the core shaft 2 is too fast, the angular velocity output by the driver 3 to the core shaft 2 can be reduced to avoid the gear lever 9 from being lifted or lowered too quickly. At the same time, when the core shaft 2 is about to rotate to the first state and when the core shaft 2 is about to rotate to the second state, the angular velocity output by the driver 3 to the core shaft 2 can be reduced in advance to reduce the angular momentum of the gear lever 9, preventing the situation where the rotational speed of the core shaft 2 is too fast and the angular momentum is too large when the core shaft 2 rotates to the first state or the second state, so that the rotation of the core shaft 2 and the gear lever 9 cannot be stopped in time, and preventing the gear lever 9 from injuring vehicles or pedestrians.

[0052] Specifically, when the core shaft 2 rotates between the first state and the second state, the first magnetic member 61 sweeps across each of the third Hall sensors 53 in sequence. The third Hall sensors 53 generate a third Hall voltage as the magnetic field increases. This third Hall voltage is the third sensing signal. According to the time difference between the appearance of the third sensing signal in adjacent third Hall sensors 53, the angular velocity of the first magnetic member 61 when it sweeps across these two third Hall sensors 53 can be measured, that is, the rotational speed of the gear lever 9. As the temperature rises, the magnetism of the first magnetic member 6 can be relatively weakened, and the third Hall voltage generated by the third Hall sensor 53 when the core shaft 2 rotates to the first state also decreases accordingly, and the third sensing signal weakens. At this time, since the first temperature compensation rod 41 can bend with the increase in temperature, the first temperature compensation rod 41 can be configured such that when the temperature is high and the core shaft 2 rotates between the first state and the second state, the end of the first temperature compensation rod 41 provided with the first magnetic member 61 bends towards the direction close to the third Hall sensor 53. In this way, when the core shaft 2 rotates between the first state and the second state, the distance between the first magnetic member 61 and the third Hall sensor 53 decreases with the increase in temperature, thereby realizing the compensation for the demagnetization of the first magnetic member 61 when the temperature rises and ensuring the sensing signal intensity of the third Hall voltage at any temperature.

[0053] As a specific solution of this embodiment, the number of the third Hall sensors 53 is equal to or more than one. The first Hall sensor 51, the third Hall sensors 53, and the second Hall sensor 52 are arranged in sequence along the path that the first magnetic member 61 sweeps across the surface of the support assembly 1 during the rotation of the core shaft 2 from the first state to the second state.

[0054] In an embodiment of the present application, please refer to Figures 3 to 6 , the temperature compensation component 4 further includes a third temperature compensation rod 43 capable of rotating synchronously with the mandrel 2, the first sensing element 5 further includes a third Hall sensor 53, and the second sensing element 6 further includes a third magnetic member 63 connected to the third temperature compensation rod 43; the number of the third Hall sensors 53 is multiple, and the third Hall sensors 53 are sequentially arranged along the path where the third magnetic member 63 sweeps across the surface of the support assembly 1 during the rotation of the mandrel 2 from the first state to the second state; one end of the third temperature compensation rod 43 is connected to the mandrel 2, the other end of the third temperature compensation rod 43 is connected to the third magnetic member 63, and the third temperature compensation rod 43 can bend towards the support assembly 1 as the temperature rises.

[0055] Specifically, when the mandrel 2 rotates between the first state and the second state, the third magnetic member 63 sequentially sweeps across each third Hall sensor 53, and the third Hall sensor 53 generates a third Hall voltage as the magnetic field increases. This third Hall voltage is the third sensing signal. According to the time difference between the appearance of the third sensing signal in adjacent third Hall sensors 53, the angular velocity of the third magnetic member 63 when it sweeps across these two third Hall sensors 53 can be measured, that is, the rotation speed of the shift lever 9; as the temperature rises, the magnetism of the third magnetic member 63 will relatively weaken, and the third Hall voltage generated by the third Hall sensor 53 when the mandrel 2 rotates to the first state will also decrease, and the third sensing signal weakens. At this time, since the first temperature compensation rod 41 can bend as the temperature rises, the first temperature compensation rod 41 can be configured to bend the end provided with the third magnetic member 63 towards the third Hall sensor 53 at high temperature and when the mandrel 2 rotates between the first state and the second state. In this way, when the mandrel 2 rotates between the first state and the second state, the distance between the third magnetic member 63 and the third Hall sensor 53 decreases as the temperature rises, thereby compensating for the demagnetization of the third magnetic member 63 when the temperature rises and ensuring the sensing signal strength of the third Hall voltage at any temperature.

[0056] In this embodiment, the structure, material, and working principle of the third temperature compensation rod 43 are the same as those of the first temperature compensation rod 41.

[0057] As a specific scheme of this embodiment, please refer to Figures 3 to 6 , the number of the third Hall sensors 53 is equal to or more than three; each third Hall sensor 53 is sequentially arranged along the path where the third magnetic member 63 sweeps across the surface of the support assembly 1 during the rotation of the mandrel 2 from the first state to the second state; the first third Hall sensor 53 is oppositely arranged with the third magnetic member 63 when the mandrel 2 is in the first state, and the last third Hall sensor 53 is oppositely arranged with the third magnetic member 63 when the mandrel 2 is in the second state.

[0058] Please refer to Figures 3 to 7 , in an embodiment of the present application, the mandrel 2 includes a mandrel body 21 that hingedly supports the assembly 1, and a rotating plate 22 that is connected to the mandrel body 21 and is located on the side of the support assembly 1 opposite to the first coupling rod. The first coupling rod is connected to the rotating plate 22.

[0059] As a specific solution of this embodiment, the second temperature compensation rod 42 and the third temperature compensation rod 43 are also connected to the rotating plate 22, and the third temperature compensation rod 43 extends along the radial direction of the mandrel body 21, and the third magnetic member 63 is connected to the end of the third temperature compensation rod 43 away from the mandrel body 21. The advantage of this is that the distance between the third magnetic member 63 and the mandrel body 21 can be extended, and the rotation radius of the third magnetic member 63 when rotating around the mandrel body 21 can be extended. In this way, when the mandrel 2 rotates between the first state and the second state, the path that the third magnetic member 63 sweeps across the surface of the support assembly 1 is longer. Furthermore, more third Hall sensors 53 can be provided to improve the measurement accuracy of the rotation speed of the mandrel 2 and the gear lever 9. More preferably, the first temperature compensation rod 41 and the second temperature compensation rod 42 are respectively arranged on both sides of the third temperature compensation rod 43, and the first temperature compensation rod 41 and the second temperature compensation rod 42 respectively extend in directions forming a first preset angle and a second preset angle with the extension direction of the third temperature compensation rod 43, where both the first preset angle and the second preset angle are not greater than 25°. This helps to reduce the area that the first temperature compensation rod 41 and the second temperature compensation rod 42 sweep across the surface of the support assembly 1 when the mandrel 2 rotates, and thus helps to reduce the volume of the barrier gate core.

[0060] Another object of the present application is to provide a barrier gate including the barrier gate core as described above.

[0061] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
