Description

Technical Field

[0001] The invention relates to an ultrasonic sensor, in particular to a portable universal ultrasonic sensor. Background Art

[0002] Existing ultrasonic sensors are generally only able to detect specific directions. However, in many cases, if an ultrasonic sensor installed in a fixed position needs to be adjusted in direction, adding probes or other methods will invisibly increase costs.

[0003] Prior art also discloses universal ultrasonic sensors, but most of them cannot detect within the entire three-dimensional space and have blind spots. For example, the patented universal ultrasonic sensor (publication number CN210038035U) discloses a universal ultrasonic sensor with a trumpet-shaped tooling opening, which has a wider signal reception range and is detachable, making it easy to manufacture. However, its design shows that the range of its ultrasonic detection is limited to the cone-shaped area pointed by the trumpet. Any other position in the entire space is a blind spot and cannot be detected by ultrasonic waves. Summary of the Invention

[0004] Purpose of the invention: The purpose of the present invention is to solve the problem that the existing universal ultrasonic sensor cannot achieve true multi-plane direction detection in the entire space.

[0005] Technical solution: To solve the above problems, the present invention adopts the following technical solution:

[0006] A portable universal ultrasonic sensor comprises a shell with at least a third-order Rubik's Cube as a prototype and corner blocks removed, the outer side surface of each unit block constituting the shell being arc-shaped, a spherical cavity being formed in the center of the shell surrounded by the multiple unit blocks, a cross-annular bracket being arranged in the spherical cavity, the inner surface of the cross-annular bracket being provided with a first groove extending along the inner surface direction, a first annular frame body being arranged in the cross-annular bracket and being adapted to the inner diameter of the bracket, at least two pulleys being respectively fixed in the grooves of the cross-annular bracket on the outer surface of the first annular frame body, a second groove and a second annular frame body being adapted to the second groove being similarly arranged on the inner surface of the first annular frame body, a third groove being arranged on the inner surface of the second annular frame body, strip-shaped fixing rods capable of sliding in the two grooves being arranged on the second and third grooves, a strip-shaped ultrasonic sensor being arranged on one side of the strip-shaped fixing rod in the longitudinal direction, and an extension shaft being fixedly connected to the inner surface of any unit block in the middle of the longitudinal direction of the strip-shaped fixing rod.

[0007] First of all, based on the shape of this design, it is completely portable. At the same time, if it is fixed through a cross-ring bracket, it can achieve detection in 18 different directions in the entire space. At the same time, a Rubik's Cube of order three or above can be used as a substitute, such as a fourth-order Rubik's Cube. It only needs to add a corresponding frame to the cross-ring frame to achieve detection in 48 directions. Therefore, as long as a sufficient number of orders is met, in theory, detection at more angles in the entire three-dimensional space can be achieved.

[0008] Furthermore, each unit block has a pulley arranged in a groove body on the outer surface of the cross-ring bracket and along the extending direction of the cross-ring bracket.

[0009] Furthermore, the cross-ring bracket is a cross-ring bracket having two rings of the same size and crossing each other in a cross shape.

[0010] Furthermore, the inner surface of each unit block has a first glass component facing the strip-shaped ultrasonic sensor probe, and a second glass component is provided on the outer surface of the current unit block and is parallel to the first glass component.

[0011] This allows the sensor probe to detect signals normally when it moves on the track of the unit block.

[0012] The strip-shaped ultrasonic sensor is parallel to the strip-shaped fixing rod, and the strip-shaped fixing rod is parallel to the extension axis.

[0013] Furthermore, one end of the strip ultrasonic sensor is an ultrasonic probe, and the other end is connected to the intersection of the cross-ring bracket through a power cord and serves as a power supply interface. The inner surface of any unit block has a power socket adapted to the power supply interface and extends to the outer surface of the current unit block.

[0014] Charging operation can only be achieved when the unit block with power supply socket is adapted to the power supply interface to prevent misoperation.

[0015] On this basis, in order to prevent the ultrasonic probe from malfunctioning, it can also be designed that the inner surface of a unit block has a path switch, and the ultrasonic sensor forms positive and negative poles at the power supply interface. Only when the unit block moves to the corresponding intersection can the ultrasonic sensor be turned on to prevent misoperation.

[0016] Furthermore, the strip-shaped ultrasonic sensor and the power supply interface are both connected to a power storage device that is disposed in the second annular frame and fixed on the cross-annular bracket.

[0017] Furthermore, the blank area after the corner blocks are removed is filled with a shielding shell fixedly connected to the cross ring bracket.

[0018] Since the strip-shaped ultrasonic sensor is parallel to the strip-shaped fixing rod, and the strip-shaped fixing rod is parallel to the extension axis, when the unit block rotates, the strip-shaped fixing rod moves in the plane, driving the ultrasonic sensor to detect in the current plane. When other planes need to be detected, it is only necessary to adjust the corresponding unit block in the unit plane.

[0019] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0020] The design solution of the present invention has a simple structure and can realize ultrasonic detection in more spatial directions in a three-dimensional space compared to the prior art, while achieving a portable effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 2 This is a schematic diagram of the structure of the present invention after removing the unit block. DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figures 1 to 2 As shown, a portable universal ultrasonic sensor includes a shell with at least a third-order Rubik's Cube as the prototype and the corner blocks removed. The outer side surface of each unit block 1 constituting the shell is arc-shaped. The center of the shell formed by the multiple unit blocks 1 forms a spherical cavity. A cross-annular bracket 2 is arranged in the spherical cavity. The inner surface of the cross-annular bracket 2 has a first groove extending along the inner surface direction (not shown, the multiple inner rings are designed here, referring to Zhang Heng's armillary sphere). A first annular frame 3 is arranged in the cross-annular bracket to match the inner diameter of the bracket. The outer surface of the first annular frame 3 has at least two fixed A pulley (not shown) is provided in the groove of the crossed annular bracket, and a second groove and a second annular frame 4 adapted to the second groove are also provided on the inner surface of the first annular frame 3. A third groove (not shown) is provided on the inner surface of the second annular frame 4. A strip-shaped fixing rod 5 capable of sliding in the two grooves is provided on the second groove and the third groove. A strip-shaped ultrasonic sensor 6 is provided on one side of the length direction of the strip-shaped fixing rod 5; an extension shaft 7 is provided in the middle of the length direction of the strip-shaped fixing rod 5 (or extends from the end where the power supply of the ultrasonic sensor is located) and is fixedly connected to the inner surface of any unit block 1.

[0026] First, based on the shape of this design, a portable effect can be fully achieved. At the same time, if it is fixed by a cross-ring bracket, 18 different directions of detection can be realized in the whole space. Moreover, a Rubik's Cube of more than three orders can be used for replacement, such as a four-order Rubik's Cube. Only by adding corresponding frames to the cross-ring frame can 48 directions of detection be achieved. Therefore, as long as the sufficient order is satisfied, theoretically, more-angle detection in the whole three-dimensional space can be realized.

[0027] Each unit block 1 is provided with a pulley disposed in a groove along the extending direction of the cross-ring bracket 2 on the outer surface of the cross-ring bracket 2.

[0028] The cross-ring bracket 2 is two cross-ring brackets with the same ring size and in a cross shape.

[0029] The inner surface of each unit block 1 has a first glass component (not shown) facing the strip ultrasonic sensor probe, and a second glass component 8 disposed on the outer surface of the current unit block 1 and parallelly cooperating with the first glass component.

[0030] So that when the sensor probe moves on the track of the unit block, the signal can be normally detected.

[0031] The strip ultrasonic sensor 6 is parallel to the strip fixing rod 5, and the strip fixing rod 5 is parallel to the extension shaft 7.

[0032] One end of the strip ultrasonic sensor 6 is an ultrasonic probe, and the other end is connected to the intersection point of the cross-ring bracket through a power cord 9 and serves as a power supply interface. The inner surface of any unit block 1 has a power supply socket 10 adapted to the power supply interface and extends to the outer surface of the current unit block 1.

[0033] Only when the unit block with the power supply socket is adapted to the power supply interface can the charging operation be realized to prevent misoperation.

[0034] On this basis, in order to prevent the misoperation of the ultrasonic probe, it can also be designed that the inner surface of one unit block has a path switch. The ultrasonic sensor forms positive and negative poles at the power supply interface. Only when the unit block moves to the corresponding intersection point can the ultrasonic sensor be turned on to prevent misoperation.

[0035] Since the strip ultrasonic sensor is parallel to the strip fixing rod, and the strip fixing rod is parallel to the extension shaft, when the unit block rotates, the strip fixing rod moves in the plane, driving the ultrasonic sensor to detect in the current plane. When detection in other planes is required, only the corresponding unit block needs to be adjusted in the unit plane.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, the strip ultrasonic sensor and the power supply interface are both connected to a power storage device (not shown) disposed within the second annular frame and fixed to the cross-annular bracket at the same time.

[0038] External power supply, such as a power bank, is not required. Instead, a rechargeable energy storage form is adopted to improve portability.

[0039] Embodiment 3

[0040] On the basis of Embodiment 1 or Embodiment 2, a shielding housing fixedly connected to the cross-annular bracket is filled in the blank area after removing the corner blocks.

[0041] It is more beautiful and the signal is more stable.
