Description

Technical Field

[0001] This utility model relates to the field of ultrasonic ranging, specifically an ultrasonic ranging device. Background Technology

[0002] Ultrasonic ranging devices need to move back and forth or perform dynamic scanning in some application scenarios to obtain more comprehensive distance information. For example, in industrial automated production lines or robot navigation systems, ultrasonic ranging devices need to be installed on mobile devices, such as robotic arms and intelligent vehicles. In addition, ultrasonic ranging devices are also required in some multi-station equipment. In this case, the ultrasonic ranging device needs to move back and forth or perform dynamic scanning to ensure that the equipment can operate safely and efficiently.

[0003] While ultrasonic ranging devices perform well in certain static scenarios within existing industrial production processes, they face challenges in dynamic ranging under specific application scenarios. For example, in industrial automated production lines or robot navigation systems, ultrasonic ranging devices typically need to be installed on mobile devices to obtain more comprehensive distance information. Furthermore, in multi-station equipment, ultrasonic ranging devices also need to move back and forth or perform dynamic scanning to ensure safe distances and efficient collaboration between workstations. Therefore, an ultrasonic ranging device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic ranging device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An ultrasonic ranging device, comprising:

[0007] The base has a hollow top and a support frame is fixedly connected to it. The support frame is cross-shaped.

[0008] A ranging component is provided, which is located on the top of the support frame. The ranging component contains a first rangefinder and a second rangefinder, and is capable of measuring distances.

[0009] Preferably, the ranging component includes:

[0010] A cross is provided on top of a support frame. A first groove and a second groove are provided inside the cross. Four support rods are fixedly connected between the cross and the support frame.

[0011] The motor is fixedly connected to the bottom of the support frame, and a rotating rod is fixedly connected to the drive end of the motor;

[0012] The two sliders are slidably connected in the first and second slide grooves, respectively.

[0013] A connecting rod is rotatably connected to a rotating rod, and the two ends of the connecting rod are respectively rotatably connected to the bottom of two sliders;

[0014] The first rangefinder, two of which are fixedly connected to the top of the two sliders respectively;

[0015] The second rangefinder, two of which are fixedly connected to the two ends of the rotating rod.

[0016] Preferably, the first slide groove and the second slide groove are perpendicular to each other, and the first slide groove and the second slide groove are connected.

[0017] Preferably, the ranging directions of the two first rangefinders are perpendicular to each other.

[0018] Preferably, the height of the two second rangefinders is less than the distance between the support frame and the cross.

[0019] Preferably, the top positions of the two second rangefinders are below the bottom surface of the connecting rod.

[0020] Preferably, the bottom ends of the four support rods are on the same plane as the bottom of the base, and the four support rods do not contact the two second rangefinders.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By setting up the ranging component and starting the motor, the motor drives the rotating rod to rotate. The rotating rod drives the connecting rod, which in turn drives the two sliders to slide in the first and second sliding grooves respectively. Specifically, when the slider in the second sliding groove moves away from the center point of the cross, the slider in the first sliding groove moves closer to the center point of the cross. That is, when the rotating rod rotates more than 90 degrees, the slider in the first sliding groove passes the center point. When the rotating rod rotates more than 180 degrees, the slider in the second sliding groove passes the center point. When the rotating rod rotates more than 270 degrees, the two sliders gradually return to their original positions. This cycle repeats, meaning that the two first rangefinders slide back and forth in the first and second sliding grooves respectively. During the back and forth sliding process, since the two first rangefinders slide back and forth in succession and the ranging directions of the two first rangefinders are perpendicular to each other, the two first rangefinders can measure distances back and forth in two different directions respectively.

[0023] At the same time, the rotation of the lever will cause the two second rangefinders to rotate in a circle, working in conjunction with the two first rangefinders to perform dynamic distance measurement. Attached Figure Description

[0029] 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.

[0030] Example 1

[0031] like Figure 1-4 As shown, in this embodiment, an ultrasonic ranging device includes: a base 100 and a ranging component 200. The top of the base 100 is hollow, and a support frame 110 is fixedly connected to the base 100. The support frame 110 is cross-shaped. The hollow top of the base 100 facilitates the placement of the motor 220, and the cross-shaped support frame 110 can effectively support the cross 210.

[0032] The ranging assembly 200 includes: a crosshair 210, a motor 220, a slider 230, a connecting rod 240, a first rangefinder 250, and a second rangefinder 260. The crosshair 210 is located on top of the support frame 110. A first groove 211 and a second groove 212 are formed through the crosshair 210. Four support rods 213 are fixedly connected between the crosshair 210 and the support frame 110. The motor 220 is fixedly connected to the bottom of the support frame 110, and a rotating rod 221 is fixedly connected to the drive end of the motor 220. The two sliders 230 are slidably connected in the first groove 211 and the second groove 212, respectively. The connecting rod 240 is rotatably connected to the rotating rod 221, and both ends of the connecting rod 240 are rotatably connected to the bottom of the two sliders 230, respectively. The two first rangefinders 250 are fixedly connected to the top of the two sliders 230, respectively. The two first rangefinders 250 are detachable and replaceable.

[0033] In this embodiment, the first slide 211 and the second slide 212 are perpendicular to each other and are connected; the ranging directions of the two first rangefinders 250 are perpendicular to each other, so that the first rangefinders 250 can measure distances back and forth in two directions.

[0034] In specific implementation, when the rotating rod 221 rotates more than 90 degrees, the slider 230 in the first slide groove 211 passes the center point. When the rotating rod 221 rotates more than 180 degrees, the slider 230 in the second slide groove 212 passes the center point. When it rotates more than 270 degrees, the two sliders 230 gradually return to their original positions, repeating the cycle. That is, the two first rangefinders 250 slide back and forth in the first slide groove 211 and the second slide groove 212 respectively. During the back and forth sliding process, since the two first rangefinders 250 slide back and forth in succession, and the distance measuring directions of the two first rangefinders 250 are perpendicular to each other, the two first rangefinders 250 can measure distances back and forth in two directions respectively.

[0035] Example 2

[0036] like Figure 1-4 As shown, in this embodiment, two second rangefinders 260 are fixedly connected to both ends of the rotating rod 221; the height of the two second rangefinders 260 is less than the distance between the support frame 110 and the cross 210; the top of the two second rangefinders 260 is below the bottom surface of the connecting rod 240; the bottom of the four support rods 213 is on the same plane as the bottom of the base 100, and the four support rods 213 do not contact the two second rangefinders 260.

[0037] In practice, the two first rangefinders 250 can measure distances back and forth in two directions respectively. At the same time, the rotation of the rotating rod 221 will drive the two second rangefinders 260 to rotate in a circle, and cooperate with the two first rangefinders 250 to perform dynamic distance measurement.

[0038] Working principle: First, the motor 220 is started, driving the rotating rod 221 to rotate. The rotating rod 221 drives the connecting rod 240 in conjunction, which in turn drives the two sliders 230 to slide correspondingly in the first groove 211 and the second groove 212. Specifically, when the slider 230 in the second groove 212 moves away from the center point of the cross 210, the slider 230 in the first groove 211 moves closer to the center point of the cross 210. That is, when the rotating rod 221 rotates more than 90 degrees, the slider 230 in the first groove 211 passes the center point; when the rotating rod 221 rotates more than 180 degrees, the slider 230 in the second groove 212 moves closer to the center point. When the center point is crossed and the rotation reaches more than 270 degrees, the two sliders 230 gradually return to their original positions, repeating the cycle. That is, the two first rangefinders 250 slide back and forth in the first slide groove 211 and the second slide groove 212 respectively. During the back and forth sliding process, since the two first rangefinders 250 slide back and forth in succession and the distance measuring directions of the two first rangefinders 250 are perpendicular to each other, the two first rangefinders 250 can measure distances back and forth in two directions respectively. At the same time, the rotation of the rotating rod 221 will drive the two second rangefinders 260 to rotate in a circle, cooperating with the two first rangefinders 250 to perform dynamic distance measurement.
