Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically a ball-type collision sensor for human-computer interaction controllers. Background Technology

[0002] In today's era of rapid technological advancement, human-computer interaction (HCI) technology has been widely applied in various fields such as smart homes, industrial control, and virtual reality. As a key device in HCI, the performance of the HCI controller directly impacts user experience and operational accuracy. The collision sensor, a crucial component of the HCI controller, plays a vital role in detecting collisions. Its sensitivity, response speed, and anti-interference capabilities are critical to the controller's normal operation and lifespan.

[0003] Meanwhile, a collision sensor with announcement number CN202423117U is disclosed, including an outer cover with fixing bolts. A bracket is fitted on the bottom of the bolts, and a screw is mounted on the bracket. The bracket is connected to an elastic element, the elastic element is connected to a suspension body, the suspension body is connected to a pendulum, and the screw is connected to the elastic element. A brush is disposed at the bottom of the pendulum, and a ring contactor is disposed outside the brush. The ring contactor is connected to a wire and leads out of the outer cover. The elastic element stabilizes the dynamic balance of the pendulum by generating a centrally symmetrical pressure on the outer end face of the pendulum. It can keep the pendulum in a stable equilibrium state during emergency braking. When an angular collision occurs, the pendulum swings to a greater than a set angle under the action of its own weight and the momentum of the collision. The spherical surface of the elastic element flips rapidly, and the brush at its lower end contacts the ring contactor, outputting an opening signal. This utility model can adapt to any angular collision and has reliable performance.

[0004] The aforementioned collision sensor can only detect contact or collision of objects during use, and cannot provide more detailed information such as collision force, angle, and speed. For non-contact collisions, such as collisions at a distance, its detection effect may be poor. As a type of mechanical collision sensor, the ball-bearing collision sensor has the characteristic of single directionality and can only detect impact signals in one direction. To achieve effective protection, multiple collision sensors need to be installed.

[0005] Therefore, a ball-type collision sensor for human-computer interaction controllers is proposed to address the above problems. Utility Model Content

A guide rail is fixedly disposed inside the fixing block, and a slider is slidably disposed inside the guide rail. Through the slider, the slider can slide flexibly on the guide rail.

[0016] Preferably, a rectangular plate is fixedly provided above the connecting plate, and a second guide rail is fixedly provided inside the rectangular plate, with the ball bearing slidingly disposed with the second guide rail.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model uses a slider that can slide flexibly on a guide rail.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The following describes an embodiment of this utility model based on its overall structure.

[0030] like Figures 1 to 4 As shown, this utility model provides a ball-bearing collision sensor for a human-computer interaction controller, including a base plate 1, a connecting plate 9 fixedly mounted on the top of the base plate 1, and fixing blocks 10 fixedly mounted on the left and right sides above the connecting plate 9. A guide rail 14 is fixedly mounted inside the fixing block 10, and a slider 12 is slidably mounted inside the guide rail 14. The slider 12 can slide flexibly on the guide rail. When it is hit by a collision, the slider 12 can quickly convert the force generated by the collision into its own displacement change. The guide rail 14 provides precise motion guidance for the slider 12, restricting the movement trajectory of the slider 12 so that it can only slide in a specific direction. This ensures reliable performance during long-term use and guarantees the service life of the sensor.

[0031] In this embodiment, a limiting rod 15 is slidably provided inside the slider 12, and the limiting rod 15 is fixedly set with the guide rail 14. A rotating shaft 13 is fixedly provided outside the slider 12. The limiting rod 15 plays a role in stabilizing the movement trajectory of the slider 12, preventing the slider 12 from deviating or shaking during the sliding process, and ensuring the stability of the movement.

[0032] A connecting post 19 is fixedly provided on the right side of the first rotating shaft 13, and a second rotating shaft 20 is fixedly provided on the right side of the connecting post 19. A ball bearing 21 is fixedly provided on the right side of the second rotating shaft 20. The ball bearing 21 is made of high-strength wear-resistant material and has a smooth surface. When it comes into contact with external objects, it can sensitively sense the collision force and transmit the force through a series of structures.

[0033] Fixing blocks 21 are fixed on both the front and rear sides of the upper part of the connecting plate 9. A magnetic triggering device 16 is fixed on the front side of the fixing block 21. The magnetic triggering device 16 can quickly react and trigger the corresponding signal when the magnetic field changes due to the collision of the ball 21.

[0034] The magnetic trigger device 16 is fixedly provided with a signal output wire 7 on the rear side, and a signal output terminal 8 is fixedly provided on the rear side of the signal output wire 7. Through the signal output wire 7, the loss in the signal transmission process can be effectively reduced, and the signal can be accurately and quickly transmitted to the signal output terminal 8 so as to connect with external devices.

[0035] A rectangular plate 17 is fixedly installed above the connecting plate 9. A guide rail 28 is fixedly installed inside the rectangular plate 17, and the ball bearing 21 is slidably installed with the guide rail 28. Through the guide rail 28, the ball bearing 21 can slide along a predetermined direction when subjected to an impact force, thereby improving the detection accuracy of the sensor.

[0036] The base plate 1 has a threaded hole 6 inside, and a threaded rod 5 is spirally provided inside the base plate 1. A fixing plate 3 is spirally provided outside the threaded rod 5. A sealing ring 2 is fixedly provided below the fixing plate 3 and is fitted to the base plate 1. A protective shell 4 is fixedly provided above the fixing plate 3. The sealing ring 2 plays a sealing role and can effectively prevent dust, moisture and other impurities from entering the sensor and affecting its normal operation.

[0037] Working principle and process of ball-type collision sensor used in human-computer interaction controller:

[0038] Before use, the sensor must be installed. Screw the threaded rod 5 into the threaded hole 6 inside the base plate 1, then screw the fixing plate 3 onto the outside of the threaded rod 5. The sealing ring 2 below the fixing plate 3 fits tightly against the base plate 1, effectively preventing dust and moisture from entering the sensor and protecting its internal structure. The protective shell 4 above the fixing plate 3 further provides physical protection for the sensor, preventing damage from external impacts. After installation, the sensor is in its initial state, with the connecting plate 9 fixed above the base plate 1, and the sliding guide rail 14 inside the fixing block 10... When block 12 is stationary, the limiting rod 15 restricts the slider 12 to slide only within the guide rail 14. The connected rotating shaft 13, connecting post 19, rotating shaft 20, and ball bearing 21 are also stationary. The magnetic triggering device 16 is not triggered, and there is no signal output from the signal output wire 7 and signal output terminal 8. When the sensor is impacted, the impact force is transmitted to the ball bearing 21. Since the ball bearing 21 is slidably connected to the guide rail 28 within the rectangular plate 17, the ball bearing 21 will slide within the guide rail 28. The sliding of the ball bearing 21 drives the rotating shaft 20, connecting post 19, and rotating rod 20. The movement of shaft 13 causes slider 12 to slide along limit rod 15 within guide rail 14. As slider 12 slides, the position of ball 21 changes. When the change in the position of ball 21 causes the magnetic field to reach the triggering condition of magnetic trigger device 16, magnetic trigger device 16 is activated. Once triggered, magnetic trigger device 16 transmits a signal through signal output wire 7 on its rear side. The signal is transmitted through signal output wire 7 to signal output terminal 8, and finally, signal output terminal 8 outputs the collision signal to human-machine interface controller. After receiving the signal, human-machine interface controller will react accordingly according to the preset program, such as adjusting the operating status of the equipment or issuing an alarm. When the collision ends and the external force disappears, slider 12 gradually stops sliding within guide rail 14, and ball 21 also stops sliding within guide rail 28, returning to a relatively stationary state. Magnetic trigger device 16 is no longer triggered, signal output wire 7 and signal output terminal 8 stop outputting signals, and the sensor returns to its initial state, waiting for the next collision to occur, thus fulfilling the function of a ball-type collision sensor for human-machine interface controller.
