Description

Technical Field

[0001] The present invention belongs to the field of trolleybuses, and particularly relates to a fixing structure for a split-angle sensor of a current collection system and an angle acquisition device. Background Art

[0002] Most of the current collection systems on the market at present adopt an integrated angle sensor, and a few current collection systems adopt a split-angle sensor.

[0003] The integrated angle sensor senses the change of the angle through a transmission shaft, converts the changed signal into an electrical signal for acquisition. This integrated angle sensor has extremely strict requirements for the assembly environment, but the accuracy of the acquired signal is relatively poor, and problems such as cracking of the transmission shaft of the sensor and signal deviation often occur.

[0004] A few current collection systems adopt a split-angle sensor. The operability of this structure by humans is relatively poor, and the experience is extremely bad every time after-sales service is carried out; at the same time, the protection of this split-angle sensor is relatively poor, and there is no protection in all three directions, and dust and dirt are easily attached to the magnetic ring, resulting in signal deviation and poor use effect; moreover, during each calibration, it is very difficult to collect angle information and it is impossible to accurately locate the angle position. Summary of the Invention

Specific implementation manner

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. 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.

[0018] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0019] As Figure 1 shown, a fixing structure of a split angle sensor for a current collection system includes a vertical main shaft 4, and a signal emitting device 1 is fixedly provided at the top of the vertical main shaft 4; and a horizontal rotating body 6 is assembled on the vertical main shaft 4, and a signal receiving device 2 is fixed on the horizontal rotating body 6 through a sensor fixing member 5.

[0020] Furthermore, the vertical main shaft 4 is assembled with the horizontal rotating body 6 through a bearing. The vertical main shaft 4 is in a static state, is a fixed structure, and does not follow the movement.

[0021] Furthermore, the signal emitting device 1 is fixed integrally with the shaft end of the vertical main shaft 4 through a setscrew 3. There are two threaded holes 11 on the side of the signal emitting device 1. The setscrew 3 is used to press tightly against the shaft end of the vertical main shaft 4 through threaded connection to ensure that the signal emitting device 1 is fastened and there is no looseness, as Figure 6 shown.

[0022] Furthermore, as Figure 7 shown, a limiting structure 41 is provided on the vertical main shaft 4. The limiting structure 41 can be steps provided on both sides of the top of the vertical main shaft 4. The signal emitting device 1 is arranged at the limiting structure 41. In this way, when the signal emitting device 1 is assembled to the shaft end of the vertical main shaft 4, it must be assembled to the limiting position to ensure accurate positioning.

[0023] Further, the sensor fixing member 5 includes a fixing frame with hollowed-out sides on both sides, and an installation plate 51 is provided at the upper end. Threaded holes are provided on the installation plate 51, and the signal receiving device 2 is installed through the threaded holes. Preferably, two threaded holes are provided on the installation plate 51, and the signal receiving device 2 is assembled to the sensor fixing member 5 through threaded connection.

[0024] Further, there are four threaded holes on each of the two hollowed-out sides of the sensor fixing member 5. The sensor sealing plate 7 is assembled to the side of the sensor fixing member 5 through threaded connection to prevent dirt, dust, and water from entering the sensor structure. In addition, there are four threaded holes on the installation plate 51 on the upper end face of the sensor fixing member 5. These threaded holes are used to assemble the plug 8, and the plug 8 is assembled to the sensor fixing member 5 through threaded connection. The plug 8 is matched with a sealing ring. Through threading and the sealing ring, it is possible to largely prevent dirt, dust, and water from entering the sensor structure, ensuring high protection and high-precision purposes.

[0025] Further, the horizontal rotating body 6 includes a rotating body main body and an upper cover 61 located on the rotating body main body. Threaded holes are provided on the upper cover 61. There are four threaded holes on the lower end face of the sensor fixing member 5. The threaded holes of the sensor fixing member are concentric with the threaded holes of the upper cover 61. The sensor fixing member 5 is fixedly connected to the upper cover 61 of the horizontal rotating body 6 through threading, improving operability and maintenance convenience.

[0026] Preferably, the sensor fixing member 5 is an integrally formed structural member, which is processed by wire cutting or milling methods without welding and bending, and the dimensional accuracy can be largely guaranteed.

[0027] As Figure 8 shown, an angle acquisition device for a current collection system includes a horizontal rotation direction split angle sensor and a vertical rotation direction split angle sensor 13; the split angle sensors in these two rotation directions have the same structure, and both include a fixedly arranged signal emitting device and a signal receiving device that rotates with the rotating body; the horizontal rotation direction split angle sensor is arranged on the sensor fixing member 5 to collect rotation angle information of the horizontal rotating body 6 performing horizontal rotation movement; the vertical rotation direction split angle sensor is arranged on the second sensor fixing member 10 to collect rotation angle information of the vertical rotating body 12 performing vertical rotation movement.

[0028] It should be noted that the split angle sensor structure of the present invention can be well applied to the current collection system. The current collection system has two rotation directions for which angle information needs to be collected, namely the vertical rotation direction and the horizontal rotation direction. An angle sensor is arranged in each of these two directions, and their structures are the same. Therefore, the present invention only takes the horizontal rotation direction split angle sensor structure as an example for description.

[0029] The working principle of the present invention is as follows: The split angle sensor consists of two parts, a signal transmitting device 1 and a signal receiving device 2; the signal transmitting device 1 is a magnetic ring structure, and this part is in a static state, that is, the reference point, namely the zero point; the signal transmitting device 1 is fixed at the shaft end of the vertical main shaft 4, and the vertical main shaft is in a static state and does not perform a rotating action. Then, the signal transmitting device 1 is fastened by a setscrew 3. Since this device is the reference zero point, the signal transmitting device 1 must be fastened in place. At the same time, the signal receiving device 2 is fixed on the sensor fixing part 5. The sensor fixing part 5 is an integral one, which is an aluminum structure part processed by wire cutting or milling, without involving welding and bending. It can not only ensure the structural strength, but also ensure the accuracy of angle signal acquisition extremely accurately. Then, the sensor fixing part 5 is assembled on the horizontally rotating horizontal rotating body 6 by a bolting method, ensuring that the sensor fixing part 5 and the horizontal rotating body 6 can be assembled into one body. When the horizontal rotating body 6 rotates horizontally at any angle, the angle information can be transmitted to the signal receiving device 2 in the first time. After that, the angle signal will be converted into an electrical signal and transmitted to the controller for acquisition, ensuring that the current collection system accurately performs the rotating action. In addition, the sensor fixing part 5 is integrally processed and formed, with both sides hollowed out and an opening at the upper end. After the split sensor is assembled, the sensor sealing plate will be assembled on the side of the sensor fixing part by a bolting method for sealing to prevent dirt, dust and water from entering. The two openings at the upper end of the sensor fixing part 5 are for fixing the signal receiving device of the split sensor. Then, four threaded holes are opened on this surface, and these threaded holes allow a screwdriver or a drill bit to enter, facilitating the assembly of the sensor fixing part onto the rotating body cover. When this part of the assembly is completed, the four holes are blocked by a plug through a threaded connection. At the same time, the plug is matched with a sealing ring, and through the thread and the sealing ring, dirt, dust and water can be greatly prevented from entering the sensor structure, ensuring the achievement of the purposes of high protection and high precision.

[0030] It should be noted that in this patent application, the signal transmitting device with a magnetic ring structure and the signal receiving device are both prior arts. The core inventive point of the present invention lies in the assembly structure of the two.

[0031] The beneficial effects of the present invention are as follows: 1. The split angle sensor of the current collection system adopts a non-contact fixed structure. Compared with the integral sensor fixed structure, the failure rate of the sensor is greatly reduced, the problem of sensor cracking is solved, and the durability and environmental adaptability are greatly improved.

[0032] 2. The fixed structure of the split angle sensor of the current collection system is integrally formed without bending or welding, which better realizes the functional fixation of the sensor, maximally ensures the dimensional installation accuracy, and further improves the accuracy of sensor signal acquisition, solves the problem of inaccurate angle sensor accuracy, and greatly reduces the failure rate of the current collection system.

[0033] 3. The fixed structure of the split angle sensor greatly reduces the assembly difficulty, improves the assembly efficiency, has a large operating space, and is convenient for debugging and maintenance.

[0034] 4. The fixed structure of the split angle sensor of the current collection system is protected in all directions, and the upper end is also blocked by a plug, with a high protection level, which can maximally prevent dirt, dust and water from entering the sensor structure, and ensure the purposes of high protection and high precision.

[0035] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the overall concept of the present invention, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present invention.
