Description

[0002] As a key component of the gate machine, the swing gate mechanism is generally arranged in the chassis of the gate machine. In order to improve the use efficiency of the gate machine, two swing gate mechanisms are generally arranged in one body to control the operation of the two gate machines. In the prior art, the body width of the dual-motor swing gate mechanism is relatively large. The body width of a dual-motor swing gate mechanism exceeds the body width of two single swing gate mechanisms, which is not conducive to the use efficiency of the gate machine and cannot achieve the goal of saving floor space. In the prior art, some of the swing gate mechanisms are arranged on the outside of the body in order to reduce the width of the body. Although the width of part of the body is reduced, the width of the body is not reduced in essence.

[0041] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant technical solutions, rather than to limit the present application. It is also necessary to explain that, for ease of description, only the parts related to the present application are shown in the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] In the embodiments of the present application, the bearing structure involved includes an inner ring and an outer ring, and balls arranged between the inner ring and the outer ring. Therefore, the inner ring and the outer ring can rotate independently of each other. For example, a certain structure is fixed on the inner ring, and the other structure is fixed on the outer ring. The two structures can maintain relatively independent rotation. For example, a certain structure fixed on the inner ring remains fixed, and the other structure fixed on the outer ring can rotate normally. Similarly, a certain structure fixed on the outer ring remains fixed, and the other structure fixed on the inner ring can rotate normally. Alternatively, a certain structure fixed on the inner ring can rotate, and the other structure fixed on the outer ring can also rotate normally.

[0044] In an embodiment of the present application, the gear structure involved includes a first end and a second end, the first end is a wheel structure, and the second end is a tooth structure. The tooth structure can be driven to rotate by a transmission chain or mutually meshing driving gears. Since the tooth structure and the wheel structure are an integrated structure, the tooth structure can control the wheel structure to rotate as a whole. Since the interior of the wheel structure is connected to an axis structure, when the tooth structure rotates, the axis structure inside the wheel structure can be driven by the wheel structure to rotate at the same angular velocity.

[0045] like Figure 1 As shown, the dual-motor coaxial movement of the gate machine of this embodiment includes:

[0046] A first motor 100, a second motor 200, a first shaft structure 300, a second shaft structure 400, and a housing 500;

[0047] The first motor 100 is connected to the first shaft structure 300, and the first motor 100 drives the first shaft structure 300 to rotate;

[0048] The second motor 200 is connected to the second shaft structure 400, and the second motor 200 drives the second shaft structure 400 to rotate;

[0049] The upper end of the second shaft structure 400 is embedded in the lower end of the first shaft structure 300, and the first shaft structure 300 and the second shaft structure 400 rotate independently of each other under the drive of the first motor 100 and the second motor 200 respectively;

[0050] The first shaft structure 300 and the second shaft structure 400 are fixed inside the housing 500, and the housing 500 is used to fix the mechanism after the first shaft structure 300 and the second shaft structure 400 are combined;

[0051] The first motor 100 and the second motor 200 are motors with the same structure. The first motor 100 and the second motor 200 are respectively fixed to two opposite sides of the housing 500 .

[0052] Specifically, in an embodiment of the present application, the setting positions of the first motor 100 and the second motor 200 do not correspond, that is, the setting position of the first motor 100 on the housing 500 and the setting position of the second motor 200 on the housing 500 are misaligned in the up and down directions. This misalignment is to enable the first motor 100 to drive the first shaft structure 300 and the second motor 200 to drive the second shaft structure 400, and the operations of the first motor 100 and the second motor 200 will not affect each other.

[0053] like Figure 2 As shown, in the embodiment of the present application, the first motor 100 includes: a motor sensing module 110, a motor body 120, a motor fixing member 130, a driving gear bearing 140, and a driving gear shaft 150;

[0054] The motor sensing module 110 is connected to the motor body 120, and the motor sensing module 110 obtains an external sensing signal and controls the motor body 120 to work after receiving the external sensing signal; specifically, for example, when the motor sensing module 110 senses a human body within a set distance, it starts working and controls the motor body 120 to work, or when the motor sensing module 110 receives a control instruction sent by an external main control module to control the start of the motor body 120, the motor sensing module 110 controls the motor body 120 to work.

[0055] The motor body 120 is fixed on the motor fixing member 130, and the motor fixing member 130 is used to fix the motor body 120 on the housing 500; Figure 2 As shown, the first end of the motor fixing part 130 is a circular ring cavity, which is fixed to the outside of the shell 500. The second end of the motor fixing part 130 is a square structure. The motor body 120 is fixed to the second end of the motor fixing part 130 by bolts. In this way, the motor body 120 is fixed to the shell 500 by the motor fixing part 130. Since the first end of the motor fixing part 130 is a cylindrical cavity structure, the output shaft of the motor body 120 can penetrate into the interior of the cylindrical cavity whose first end is the motor fixing part 130.

[0056] The driving gear bearing 140 is arranged inside the motor fixing part 130, and the driving gear bearing 140 is fixed inside the motor fixing part 130 so that the position of the driving gear bearing 140 remains unchanged; at this time, if the motor body 120 rotates, the driving gear shaft 150 is driven to rotate, and since the outer ring of the driving gear bearing 140 is fixed inside the motor fixing part 130, the driving gear shaft 150 will rotate on the inner ring of the driving gear bearing 140.

[0057] The driving gear shaft 150 is arranged inside the driving gear bearing 140. The first end of the driving gear shaft 150 is connected to the output shaft of the motor body 120. The second end of the driving gear shaft 150 is connected to the first shaft structure 300. The driving gear shaft 150 is fixed inside the motor fixing part 130 through the driving gear bearing 140. The driving gear bearing 140 controls the positions of the driving gear shaft 150 and the motor body 120 to remain unchanged. The driving gear shaft 150 is driven by the output shaft of the motor body 120 to rotate on the inner ring of the driving gear bearing 140, and when the motor body 120 rotates, it rotates at a set angular velocity, driving the first shaft structure 300 to move at a corresponding speed. Due to the alignment of the gears of the driving gear shaft 150 and the teeth of the first shaft structure 300,

[0058] The wheels are meshed, so the gear rotation speed of the driving gear shaft 150 is consistent with the gear rotation speed of the first shaft structure 300. By setting the diameter ratio of the gear of the driving gear shaft 150 and the gear of the first shaft structure 300, the first shaft structure 300 can be rotated at an increasing angular velocity, a decreasing angular velocity or a constant angular velocity, thereby achieving precise control of the rotation speed of the first shaft structure 300.

[0059] In one embodiment of the present application, Figure 3 As shown, the first shaft structure 300 includes: a first stop bearing 310, a first shaft 320, a first inter-shaft fixed bearing 330, a first driven gear 340, and a first limiter 350;

[0060] The outer ring of the first stop point bearing 310 is fixed to the inner upper side of the housing 500, the first end of the first shaft 320 is fixed to the inner ring of the first stop point bearing 310, the second end of the first shaft 320 is provided with an annular expansion protrusion, so that the outer diameter of the second end of the first shaft 320 is larger than the outer diameter of the first end, the annular expansion protrusion at the second end of the first shaft 320 is used to set the first inter-axis fixed bearing 330, the first stop point bearing 310 is used to fix the position of the first shaft 320, when the first shaft 320 rotates, the inner ring of the first stop point bearing 310 rotates, and the outer ring of the inter-axis fixed bearing rotates; specifically, the function of the first stop point bearing 310 is to keep the position of the first shaft 320 relative to the housing 500 unchanged, so as to achieve the purpose of fixing the first shaft structure 300, because the first shaft 320 is fixed to the inner ring of the first stop point bearing 310, therefore, the first shaft 320 can rotate freely in the inner ring of the first stop point bearing 310.

[0061] The outer ring of the first inter-axis fixed bearing 330 is fixed on the first shaft 320, and the inner ring of the first inter-axis fixed bearing 330 fixes the second shaft structure 400, so that the first shaft 320 and the second shaft structure 400 maintain independent rotation. Specifically, since the inner ring and the outer ring of the first inter-axis fixed bearing 330 can maintain relatively independent rotation, the first shaft 320 and the second shaft structure 400 can be made independent of each other through the first inter-axis fixed bearing 330, so that there is no contact between the two, no friction between the two, and the relative position between the two can be fixed. At the same time, since the first end of the second shaft structure 400 is arranged inside the first shaft 320, the length of the two shaft structure connector is reduced.

[0062] The first end of the first driven gear 340 is connected to the first shaft 320, and the second end is connected to the first motor 100. The first driven gear 340 controls the first shaft 320 to rotate under the drive of the first motor 100. Specifically, since the first end and the second end of the first driven gear 340 are respectively connected to the first shaft 320 and the first motor 100, the first driven gear 340 drives the first shaft 320 to rotate under the control of the first motor 100 under the drive of the first motor 100. In the embodiment of the present application, due to the isolation effect of the first inter-shaft fixed bearing 330, when the first shaft 320 rotates, the second shaft structure 400 will not be driven to rotate;

[0063] The first limiter 350 is arranged on the first driven gear 340. When the first motor 100 drives the first driven gear 340 to rotate, the first limiter 350 is used to control the rotation angle of the first driven gear 340. When the first motor 100 stops working, the first limiter 350 is used to control the first driven gear 340 to restore to an initial state.

[0064] In one embodiment of the present application, Figure 4 As shown, the second shaft structure 400 includes: a second stop bearing 410, a second driven gear 420, a second shaft 430, and a second limiter 440;

[0065] The second stop bearing 410 is arranged on the lower inner side of the housing 500, and the second end of the second shaft 430 is fixed on the inner ring of the second stop bearing 410. The second stop bearing 410 is used to keep the relative position of the second shaft 430 and the housing 500 unchanged. The first end of the second shaft 430 is fixed on the second driven gear 420, and the second shaft 430 rotates under the drive of the second driven gear 420. Specifically, the function of the second stop bearing 410 is to keep the position of the second shaft 430 relative to the housing 500 unchanged, so as to achieve the purpose of fixing the second shaft structure 400. Since the second shaft 430 is fixed on the inner ring of the second stop bearing 410, the second shaft 430 can rotate freely on the inner ring of the second stop bearing 410.

[0066] The second driven gear 420 is connected to the second motor 200, and the second motor 200 drives the second driven gear 420 to rotate at a set speed. Specifically, since the first end and the second end of the second driven gear 420 are respectively connected to the second shaft 430 and the second motor 200, the second driven gear 420 drives the second shaft 430 to rotate under the control of the second motor 200 under the drive of the second motor 200. In the embodiment of the present application, due to the isolation effect of the first inter-shaft fixed bearing 330, when the second shaft 430 rotates, the first shaft structure 300 will not be driven to rotate. That is, the rotation of the first shaft structure 300 and the second shaft structure 400 are independent of each other. However, since the first end of the second shaft 430 is deep into the interior of the first shaft structure 300, the combined length of the first shaft structure 300 and the second shaft structure 400 is much smaller than the sum of the length of the first shaft structure 300 and the length of the second shaft structure 400, and the rotation of the two is independent of each other;

[0067] The second limit 440 is set on the second driven gear 420. When the second motor 200 drives the second driven gear 420 to rotate, the second limit 440 is used to control the rotation angle of the second driven gear 420. When the second motor 200 stops working, the second limit 440 is used to control the second driven gear 420 to restore to an initial state.

[0068] In a specific embodiment of the present application, Figure 5 As shown, the housing 500 includes a main housing 510, a housing upper cover 520, and a housing lower cover 530;

[0069] A through cylindrical cavity is disposed at the center of the main housing 510, and the housing upper cover 520 and the housing lower cover 530 are disposed at the upper opening and the lower opening of the cylindrical cavity of the main housing 510 respectively;

[0070] The first shaft structure 300 is fixed on the inner surface of the housing upper cover 520 , and the second shaft structure 400 is fixed on the inner surface of the housing lower cover 530 ;

[0071] Circular holes are respectively arranged on the sides of the main shell 510, and the circular holes penetrate into the cylindrical cavity of the main shell 510. The circular hole on one side of the main shell 510 is used to install the first motor 100 for driving the first shaft structure 300, and the circular hole on the other side of the main shell 510 is used to install the second motor 200 for driving the second shaft structure 400.

[0072] Specifically, in the embodiment of the present application, the first motor 100 and the second motor 200 are brushless motors or servo motors. The specific embodiments of the present application include but are not limited to these two types of motors.

[0073] The first driven gear 340 is meshed with the output gear of the first motor 100 , and the output gear of the first motor 100 drives the first driven gear 340 to rotate at the same speed.

[0074] The second driven gear 420 is meshed with the output gear of the second motor 200 , and the output gear of the second motor 200 drives the second driven gear 420 to rotate at the same speed.
