Detailed implementation mode

[0024] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] As Figure 1 — shown in Embodiment 1 of Figure 5

[0027] An embedded ball screw barrier gate machine includes a mounting base 1. A first bracket 2 is rotatably arranged between the inner side walls of the bottom of the mounting base 1. A main shaft 5 is rotatably arranged on the top of the mounting base 1. A barrier arm 4 is installed at the end of the main shaft 5. A rocker arm 6 is installed on the outer surface of the main shaft 5. One end of the inner side wall of the rocker arm 6 is rotatably installed with a second bracket 7. A motor lead screw assembly 3 is installed on the first bracket 2, and the power output end of the motor lead screw assembly 3 is in transmission connection with the second bracket 7. The motor lead screw assembly 3 can make the rocker arm 6 drive the main shaft 5 to rotate so that the barrier arm 4 rotates.

[0028] By starting the motor lead screw assembly 3 to drive the rocker arm 6 to rotate, the main shaft 5 fixedly installed with the rocker arm 6 is also driven to rotate, and then the barrier arm 4 swings. By using the motor lead screw assembly 3 as the power source and power transmission component to replace the traditional speed reducer, while realizing the function of speed reduction, the overall occupied space is also reduced. The motor lead screw assembly 3 has the advantages of simple structure, low cost, small occupied space, and convenient use compared with the motor gear speed reducer transmission method.

[0029] The motor lead screw assembly 3 includes a motor installed at the bottom of the first bracket 2. A lead screw 34 is provided at the power output end of the motor, and the lead screw 34 extends through the first bracket 2 and is in transmission connection with the second bracket 7. The motor includes a motor stator 31. An end cover 32 is fixedly installed on the upper part of the motor stator 31, and the end cover 32 is located between the first bracket 2 and the motor stator 31. A rotor assembly 33 is provided inside the motor stator 31, and the lead screw 34 is arranged inside the rotor assembly 33.

[0030] The lead screw 34 is composed of a non-threaded section located in the rotor assembly 33 and a threaded section in transmission connection with the second bracket 7. The non-threaded section replaces the rotating shaft of the traditional rotor assembly 33, so that the lead screw 34 and the rotor assembly 33 are integrally arranged, thus making the lead screw 34 and the motor an integral body.

[0031] Refer to Figure 2 and Figure 3 , the non-threaded section of the lead screw 34 replaces the rotating shaft in the traditional rotor assembly 33, so that the lead screw 34 and the motor are integrally arranged, thus realizing a low-cost embedded ball screw. When in use, the rotation of the rotor assembly 33 drives the rotation of the lead screw 34. Since the lead screw 34 is in transmission connection with the second bracket 7, the rotation of the lead screw 34 drives the second bracket 7 to move, thereby driving the swing arm 6 to rotate, and further driving the main shaft 5 to rotate and the barrier rod 4 to swing. During the process of the lead screw 34 driving the second bracket 7 to move and driving the swing arm 6 to rotate, since the second bracket 7 is rotationally connected to the swing arm 6 and the first bracket 2 is rotationally connected to the second mounting bracket 12, certain rotations will also occur to the first bracket 2 and the second bracket 7 when the swing arm 6 rotates, thus avoiding movement interference.

[0032] The mounting base 1 includes a first mounting bracket 11 and a second mounting bracket 12 fixedly connected to the inner side wall of the first mounting bracket 11. The first bracket 2 is rotatably installed between the inner side walls at the bottom of the second mounting bracket 12.

[0033] A buffer assembly 9 is further provided between the main shaft 5 and the mounting base 1. The buffer assembly 9 includes a fixing bracket 91 fixedly installed on the outer surface of the main shaft 5. A connecting shaft 92 is arranged between the inner side walls at the end of the fixing bracket 91 away from the main shaft 5. A base 93 is provided at the lower end of the mounting base 1. A plurality of buffer connectors 94 are arranged between the connecting shaft 92 and the base 93. The buffer connectors 94 are springs.

[0034] Through the telescopic force of the buffer connectors 94, the impact force brought to the lead screw 34 by the movement of the lead screw 34 driving the second bracket 7 and the rotation of the swing arm 6 and the barrier rod 4 is buffered, which plays a role in protecting the lead screw 34 to a certain extent and improves the service life of the lead screw 34.

[0035] The first limiting shaft 10 and the second limiting shaft 8 are respectively installed on the outer surface of the side wall of the second mounting frame 12, the first limiting shaft 10 and the second limiting shaft 8 are located on both sides of the first mounting frame 11, and the first limiting shaft 10 and the second limiting shaft 8 are staggered;

[0036] The position of the second mounting frame 12 is restricted when the second mounting frame 12 rotates with the first mounting frame 11, so as to prevent other components of the barrier gate from being damaged due to excessive rotation angle.

[0037] The base 93 includes a connecting plate 931 installed between the inner side walls of the first mounting frame 11, a fixing plate 932 is fixedly installed at the edge of the upper surface of the connecting plate 931, and a plurality of limiting grooves 933 are opened on one side of the fixing plate 932; a fastening groove 935 is opened on the side of the connecting plate 931, and a limiting plate 934 adapted to the limiting groove 933 is arranged on the outer surface of the connecting rod at the bottom of the buffer connecting member 94, and the connecting rod passes through the limiting plate 934 and extends to the inside of the fastening groove 935, and the bottom of the connecting rod is threadedly connected with a first nut 936 and a second nut 937, and the first nut 936 is close to the inner bottom wall of the connecting plate 931, and the buffer connecting member 94 has a certain telescopic force;

[0038] The upper and lower positions of the connecting rod are limited by the limit plate 934, and the connecting rod and the connecting plate 931 are fixed by the first nut 936, so as to fix the end of the buffer connector 94. The second nut 937 is set to form a double nut anti-separation structure with the first nut 936 to prevent the buffer connector 94 from separating from the connecting plate 931 when the first nut 936 cannot play a fixing role. The second nut 937 is used as a guarantee to prevent the buffer connector 94 from separating from the connecting plate 931.

[0039] The first nut 936 is a butterfly nut, which is convenient for people to tighten it directly by hand without using a screwing tool.

[0040] The working process of the present invention is as follows: when in use, the rotor assembly 33 first drives the screw rod 34 to rotate. Since the screw rod 34 is connected to the second bracket 7 by transmission, the second bracket 7 is driven to move; the movement of the second bracket 7 drives the rocker arm 6 to rotate, and also drives the main shaft 5 to rotate, and then drives the barrier rod 4 installed at the end of the main shaft 5 to rotate at a certain angle, thereby achieving a blocking effect.

[0041] Embodiment 2: This embodiment is different from the above embodiment in that the motor screw assembly 3 can also be replaced by a linear drive component such as a cylinder, a hydraulic cylinder, an electric push rod, etc.;

[0042] The principles of other components of this embodiment are the same as those of the above embodiment and will not be described in detail here.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
