The specific meaning of the above terms in the present creation can be understood by a person of ordinary skill in the art.

Referring to FIG. 1, an embodiment of a direction sensor is disclosed. The direction sensor 100 includes two electrode guiding portions 1, 1', and the two electrode guiding portions 1. 1' is formed with a gap (not shown); at least six contact pins 2, the two electrode guiding portions 1, 1' and the at least six contact pins 2 define a space 31; the moving member 3, the moving member 3 The signal processing circuit (not shown) is electrically connected to a signal end of the signal processing circuit, and the at least six touches are respectively connected to the signal processing circuit (not shown). The foot 2 is electrically connected to another signal end of the signal processing circuit; When the direction is sensed, the moving member 3 moves in the space 31 according to the sensed direction, and contacts the contact foot 2 below the corresponding direction, thereby causing the electrode guiding portion 1, 1' to pass the movement The component 3 forms a sensing signal loop with the contact pin 2 below the corresponding direction. That is to say, the moving member is in contact with the contact pin 2 corresponding to the direction and located below.

In the present embodiment, the two electrode guiding portions 1, 1' are disposed obliquely. and also That is, the two electrode guiding portions 1, 1' form a predetermined oblique angle with the horizontal plane, and the angle of the oblique angle ranges between more than zero degrees and less than ninety degrees. The at least six contact pins 2 correspond to six sensing directions. That is to say, at least one contact pin 2 corresponds to each sensing direction. It should be noted that the six sensing directions are the six flipping directions of the sensed object, such as front, rear, upper, lower, left and right. That is, the at least six contact pins 2 correspond to six stereo flipping sensing directions. In summary, regardless of the shape of the object, the direction sensor 100 can sense the six flip directions of the object. When the sensed object does not flip, the direction sensor 100 does not sense the direction regardless of whether the sensed body weight changes. The direction sensor 100 senses the direction in which the inversion occurs only when the sensed object is flipped.

In this embodiment, the number of the contact pins 2 is six, and then one contact pin 2 is corresponding in each sensing direction. The at least six contact pins 2 are annularly disposed, specifically the at least six contact pins 2 are arranged in a hexagonal shape (shown in Figure 2), and the preferred embodiment is substantially hexagonal.

In the present embodiment, the two electrode guiding portions 1, 1' are disposed opposite to each other and form the gap. The at least six contact pins 2 are annularly arranged to form an annular space, and the distance between the adjacent two contact pins 2 is smaller than the minimum diameter of the moving member 3, so that the moving member 3 can be prevented from the at least six contact pins 2 slipped. The two electrode guiding portions 1, 1' and the at least six contact pins 2 define the space 31, that is to say the space 31 is constituted by the gap and the annular space.

In this embodiment, the at least six contact pins 2 are not associated with the two electrodes. The lead portions 1 , 1 ′ are in contact with each other, and the at least six contact pins 2 are away from the two electrode guiding portions 1 , 1 ′, that is, the at least six contact pins 2 and the two electrode guiding portions 1 , 1 ′ The at least six contact pins 2 are suspended at a distance. The length of the at least six contact pins 2 may be greater than, equal to, or less than the width of the gap, and the width of the gap refers to the distance between the two electrode guiding portions 1, 1'. It should be noted that the at least six contact pins 2 may be disposed between the planes of the two electrode guiding portions 1 , 1 ′, that is, the length of the at least six contact pins 2 is smaller than the gap. The width of the at least six contact pins 2 ensures that the moving member 3 does not slip out of the space 31, and that the moving member 3 can be secured with the at least six contact pins 2 Contact any one of the contact pins 2.

In this embodiment, the contact pins 2 are substantially perpendicular (90 degrees) to the plane in which the two electrode guiding portions 1, 1' are located. The at least six contact pins 2 are made of a conductor material, and the at least six contact pins 2 may also be made of an insulating material. When the at least six contact pins 2 are made of an insulating material, a conductor is required to be plated on the surface of the at least six contact pins 2. The common conductor material may be aluminum, copper, iron, alloy, etc., which is used in the present invention. The conductor material is not limited to this, and is not exemplified here, and may be selected according to actual needs.

In this embodiment, the width of the gap is greater than the largest diameter of the moving member 3. The moving member 3 is substantially spherical, that is, spherical or ellipsoidal, and the width of the gap is greater than the maximum diameter of the ball. The shape of the moving member 3 is not limited to a spherical shape, and may be other shapes, which will not be exemplified herein as long as the moving member 3 is moved in the space 31, and according to the sensing direction and the pair It should be contacted by the contact pin 2 below the direction.

In this embodiment, the moving member 3 is made of a conductor material, and the moving member 3 can also be made of an insulating material. When the moving member 3 is made of an insulating material, a conductor is required to be plated on the surface of the moving member 3. The common conductor material may be aluminum, copper, iron, alloy, etc., and the conductor material used in the creation is not limited. Here, the examples are not repeated here, and can be selected according to actual needs.

In this embodiment, the two electrode guiding portions 1, 1 ′ are two frames, and the two electrode guiding portions 1 , 1 ′ have a cross section of two triangles, that is, the frame is triangular. That is, the two electrode guiding portions 1, 1 ' are two triangular frames. Specifically, the frame is an equilateral triangle, and the frame may also be a triangle of other shapes (not drawn). The two triangles are relatively rotated by a predetermined angle. In the embodiment, the predetermined angle of rotation is 180 degrees, that is, the two triangles are relatively rotated by 180 degrees, then the at least six contact pins 2 are arranged in a regular hexagon. In fact, the two aforementioned triangles are rotated relative to each other by a predetermined angle between 150 degrees and 210 degrees or less (not drawn).

In this embodiment, the diameter of the inscribed circle of the two electrode guiding portions 1, 1' is smaller than the minimum diameter of the moving member 3, that is, the diameter of the inscribed circle of the triangle is smaller than the minimum of the ball. The diameter is such that the ball can be effectively prevented from rolling off the triangle, i.e., the moving member 3 is prevented from slipping off from the two electrode guides 1, 1 '.

In the present embodiment, the two electrode guiding portions 1, 1' are respectively made of a conductor material, and the two electrode guiding portions 1, 1' may also be made of an insulating material. When the two electrode guiding portions 1, 1 ′ are made of an insulating material, it is necessary to plate a layer of conductors on the surfaces of the two electrode guiding portions 1 , 1 ′. The common conductor material may be aluminum. copper, Iron, alloy, etc., the conductor material used in this creation is not limited to this, and will not be exemplified here, and can be selected according to actual needs.

In this embodiment, it is further explained that the moving member 3 moves in the space 31, and the force for moving the moving member 3 is gravity. When the sensed object is deflected, the moving member 3 moves under the action of gravity to the contact foot 2 corresponding to the downward direction. During the movement, the moving member 3 is guided along one of the electrodes. The contact portion 2 in the lead portion 1, 1' or other sensing direction moves (rolls) to the contact pin 2 below the corresponding direction, thereby bringing the moving member 3 into contact with the contact pin 2 below the corresponding direction.

In the present creation, the two electrode guiding portions 1, 1' serve two purposes. One is a guiding function, and when the direction is sensed, the moving member 3 is guided by gravity along one of the two electrode guiding portions 1, 1 ', toward the contact pin 2 In the directional movement, the contact pin 2 corresponds to the sensing direction and is located below it, so that the moving member 3 is in contact with the contact pin 2 below the sensing direction. The two electrode guiding portions 1 , 1 ′ mainly guide the moving direction of the moving member 3 , that is to say, the two electrode guiding portions 1 , 1 ′ are equivalent to the track, and are sensed. The direction of movement causes the moving member 3 to move on the correct track so that it comes into contact with the correct contact foot 2.

The other is the function of the electrode, at least one of the two electrode guiding portions 1, 1' is in contact with the moving member 3 regardless of whether the moving member 3 is moved or not. The two electrode guiding portions 1, 1' are electrically connected to a signal end of the signal processing circuit.

In this embodiment, the position where the at least six contact pins 2 are located and the third The angle of the angle corresponds to the angle, and the moving member 3 moves along the triangle in the space 31. The advantage of the design is that it is convenient to guide the moving member 3 to the corresponding sense when sensing the direction. Contact pin 2 below the direction of measurement.

In this embodiment, the two electrode guiding portions 1 and 1 ′ are respectively electrically connected to the signal output end of the signal processing circuit, and the at least six contact pins 2 are respectively connected to the signal input end of the signal processing circuit. Electrical connection. Or the two electrode guiding portions 1, 1' are electrically connected to the signal input end of the signal processing circuit, and the at least six contact pins 2 are electrically connected to the signal output end of the signal processing circuit. For the specific structure of the signal processing circuit, please refer to FIG. 2 and related content.

The present working principle is that before the inversion, the direction sensor 100 is obliquely disposed on or inside the surface of the object to be sensed, and the electrode guiding portion 1 is located above, assuming that the electrode guiding portion 1' is located below. The contact pin 2 corresponding to the sensing direction on the sensed object is located below, and the contact pin 2 corresponding to the sensed direction under the sensed object is located above. The moving member 3 is in contact with the contact pin 2 located below, and the moving member 3 is also in contact with the electrode guiding portion 1' located below, so that the contact pin 2, the moving member 3 and the electrode located below The guiding portion 1' forms a sensing signal loop, and the direction sensed by the direction sensor 100 is the upper sensing direction before the object is flipped.

After flipping, it is assumed that the sensed object is flipped by 180 degrees, that is, the upper sensed direction before the sensed object is turned into the lower sensed direction after the flip, and the lower sensed direction before the sensed object is turned over becomes The upper sensing direction after flipping. At this time, the electrode guiding portion 1' is located above, and the electrode guiding portion 1 is located below. The lower sensing direction before being turned over by the sensed object becomes After the flipped upper sensing direction, the contact pin 2 corresponding to the lower sensing direction before the flipping is now located below, and then the contact pin 2 corresponding to the upper sensing direction before the flipping is located above. The moving member 3 is in contact with the contact pin 2 located below, and the moving member 3 is also in contact with the electrode guiding portion 1 located below, so that the contact pin 2, the moving member 3 and the electrode guiding portion 1 are A sensing signal loop is formed, and the direction sensed by the direction sensor 100 is the lower sensing direction before the object is flipped. By analogy, other sensing directions of the sensed object are not exemplified here.

During the inversion process, the moving member 3 comes into contact with the electrode guiding portion 1 from the contact with the electrode guiding portion 1', and the contact pin 2 located below when the inversion is turned over is located above, and the moving member 3 is in gravity. Under the action of the contact pin 2 located above, and along the guiding of the electrode guiding portion 1, the direction of the contact pin 2 located below the flipping direction is moved until the moving member 3 and the footing below 2 contact. During the guiding of the electrode guiding portion 1, the electrode guiding portion 1 can only guide the moving member 2 into contact with the lower contact pin 2, and it is impossible to guide the moving member 3 to The contact pins 2 of other positions (directions) are in contact.

In the present invention, it should be emphasized that when the direction sensor 100 is used to sense the direction, the direction sensed by the direction sensor 100 is always above, then the contact pin 2 corresponding to the sensing direction must be Located below. That is to say, the direction sensor 100 is sensed only when the sensed direction is above, and the contact pin for the sense direction must be located below. Regardless of how the object to be sensed is flipped, the contact foot 2 located below must correspond to the upper sensing direction of the sensed object after the flip, and one of the two electrode guiding portions 1, 1' will always be said The moving member 2 is guided to the contact pin 2 located below, so that the moving member 3 It is in contact with the contact pin 2 located below.

In the present invention, the contact pins 2 are substantially perpendicular to the plane in which the two electrode guiding portions 1, 1' are located (90 degrees). In fact, the contact pins 2 can also be located with the two electrode guiding portions 1, 1 ' The plane is at a predetermined angle, and the range of the predetermined angle is between zero degrees and less than or equal to 90 degrees.

In this creation, the number of the feet 2 is not limited to six. The number of the contact pins 2 may be seven, eight, nine, etc., and the description of the contact pins 2 is not repeated here, as long as the number of the contact pins 2 is at least six. Also, in other embodiments of the present creation, the number of the contact pins 2 is also six. In other words, the present creation will focus on a plurality of embodiments of the direction sensor 100 in which the number of the contact pins 2 is six.

In the present creation, the contact pins 2 corresponding to one of the sensing directions are replaced by a limiting member (not drawn), and the limiting member is not electrically connected to the signal processing circuit. That is, the remaining contact pins 2 are electrically connected to the signal processing circuit, respectively, and the limiting member is not electrically connected to the signal processing circuit.

The description is made by taking the number of the contact pins 2 as six, that is, the six contact pins 2 become five contact pins 2 and one of the restriction members, and the restriction member replaces one of the contact pins 2. The five contact pins 2 are electrically connected to the signal processing circuit, and the limiting member is not electrically connected to the signal processing circuit. When the direction is sensed, the moving member 3 is in contact with the limiting member corresponding to the sensing direction. When the signal processing circuit cannot detect the sensing signal, the signal processing circuit accurately The direction corresponding to the restriction member is sensed. That is, when the direction sensor senses a direction corresponding to the restriction member, The signal processing circuit cannot detect the sensing signal, and the sensing signal can be detected only when the direction sensor senses the direction corresponding to at least one of the five contact pins 2.

The restricting member may be made of an insulating material or may be made of a conductor material, and the shape of the restricting member may be a rod shape, a sheet shape or the like. Regardless of the material used for the restriction member and regardless of its shape, as long as the restriction member corresponds to one of the sensing directions, and the restriction member is not electrically connected to the signal processing circuit, The other five contact pins 2 are connected to the signal processing circuit and can still achieve the purpose of sensing six directions. In the present creation, when the number of the contact pins 2 is greater than six (not drawn), at least two contact pins 2 are corresponding in at least one sensing direction, that is, at least two contact pins 2 are used for sensing. The same sensing direction. For example, when the number of the contact pins 2 is seven, it means that one of the sensing directions corresponds to the two contact pins 2. The advantage that the number of the contact pins 2 is greater than six is that, in a sensing direction corresponding to at least two of the contact pins 2, even if one of the contact pins 2 is damaged, the other contact pins 2 can work normally, so that Affecting the normal operation of the direction sensor 100. It should be noted that, how the number of the contact pins 2 is greater than six is set by a person skilled in the art according to the embodiment, and the number of the contact pins 2 is no longer greater than six. An example of how to set it up.

In the present creation, the annular arrangement of the at least six contact pins 2 may be arranged in a hexagonal shape, or may be arranged in a circle, a heptagon, an octagon, a hexagon, or the like, that is, the at least six The ring-shaped arrangement of the contact pins 2 is not limited to a hexagon, and may be set to other shapes depending on the number of the contact pins 2. Regardless of the circular arrangement of the shape of the at least six contact pins 2, only It can be ensured that each of the sensing directions corresponds to at least one of the contact pins 2, and when the moving member 3 moves in the space 31, it can be contacted with at least one of the contact pins 2 corresponding to each of the sensing directions.

In the present invention, the two electrode guiding portions 1, 1 ′ are two frames, and the structures of the two electrode guiding portions 1 , 1 ′ can be deformed according to actual needs, that is, the two electrodes The guiding portions 1, 1 ' may be recessed, through holes or the frame or a combination of any two.

In the present creation, the shape of the cross section of the two electrode guiding portions 1, 1 ' may also be a geometric shape or an irregular geometric shape, which is a circle, an ellipse, a triangle, a pentagon, and a sixth. Edge or heptagon and so on. In summary, the electrode guiding portions 1, 1 ' may be recessed portions having a geometrical or irregular geometry in cross section, or the electrode guiding portions 1, 1 ' may be geometric or irregular in cross section. The through holes, or electrode guides 1, 1 ' may be the frame having a cross-sectional geometry or an irregular geometry.

In the present creation, the two electrode guiding portions 1, 1' function that, regardless of how the object to be sensed is reversed, one of the two electrode guiding portions 1, 1' will always move the moving member 3 is guided to the contact pin 2 located below, so that the moving member 3 is in contact with the contact pin 2 located below, and it is impossible to guide the moving member 3 to contact with the contact pin 2 at other positions (directions). .

In the present creation, the diameter of the inscribed circle of the two electrode guiding portions 1, 1 ' is smaller than the minimum diameter of the moving member 3, and the structure is mainly for the two electrode guiding portions 1, 1 'One of the cases is the through hole or the frame, excluding the recessed portion, and only when the through hole or the frame is formed, the moving member 3 is possible from the two electric The pole guides 1, 1' slide down.

In the present invention, the opposite direction means that when the direction sensor 100 is obliquely disposed, the contact foot 2 located below the at least six contact pins 2, that is, the lowest level of the position. The foot of the foot 2 (see Figure 13).

Referring to FIG. 2, FIG. 2 is a schematic structural view of the embodiment shown in FIG. 1 in a top view and refilled signal processing circuit. The working principle and structure of the direction sensor 100 in FIG. 2 are the same as the working principle and structure of the direction sensor 100 in FIG. 1 , and the description thereof will not be repeated here. For details, please refer to FIG. 1 and the description of FIG. 1 . . The specific content of the signal processing circuit is as follows: In this embodiment, the power supply 8 and at least six resistors 9 are further included. The two electrode guiding portions 1 , 1 ′ are respectively electrically connected to the power source 8 , the at least six contact pins 2 are respectively grounded through the at least six resistors 9 , and the at least six contact pins 2 are also respectively connected to the signal The input of the processing circuit 6 is electrically connected.

In this embodiment, the resistor 9 and the ground are provided with a normal low state for each input terminal of the signal processing circuit 6. When the contact pin 2 corresponding to one of the sensing directions is in contact with the moving member 3, and the electrode guiding portion 1 or 1' is also in contact with the moving member 3, the signal processing circuit corresponding to the contact pin 2 The input of 6 will change to a high level.

The present invention is not limited to the above connection manner, and may be reversed as follows. The two electrode guiding portions 1, 1' are electrically connected to a low (or ground) potential, and the at least six contact pins 2 are electrically connected to the resistor 9 High potential, each input of the signal processing circuit 6 is provided A normal high state. When the contact pin 2 corresponding to one of the sensing directions is in contact with the moving member 3, and the electrode guiding portion 1 or 1' is also in contact with the moving member 3, the signal processing circuit corresponding to the contact pin 2 The input of 6 will change to a low (or ground) potential. In the present creation, the signal processing circuit 6 is not limited to the above structure, and may be other structures. The signal processing circuit 6 may be a circuit that does not include an MCU, or may be a circuit that includes an MCU.

In the present invention, when the signal processing circuit 6 is a circuit that does not include an MCU, an LED lamp may be disposed in the signal processing circuit 6, and the sensing direction may be determined according to the switch or the color of the LED light, that is, when corresponding When the contact pin 2 under one of the sensing directions is in contact with the moving member 3, the LED lamp corresponding to the direction will emit light or emit a corresponding color of light. Specifically, when the contact pin 2 corresponding to one of the sensing directions is in contact with the moving member 3, and the electrode guiding portion 1, 1' is in contact with the moving member 3, then the LED lamp corresponding to the direction It will illuminate, and the LED lights in other directions will not illuminate (extinguished); or the LED lights in the direction will emit different colors of light. When people see the LED lights emitting different colors of light, they will judge immediately. The direction sensed by the direction sensor 100 is derived.

In the present invention, when the signal processing circuit 6 is a circuit including an MCU, the two electrode guiding portions 1, 1' or the at least six contact pins 2 are electrically connected to the input terminals of the MCU, respectively.

In the present invention, the signal processing circuit 6 can sense the direction by two ways. The first mode is as shown in the figure, when there is one electrode guiding part 1 in the two electrode guiding parts 1, 1 ' 1' is in contact with any one of the at least six contact pins 2 by the moving member 3 to form a sensing signal loop, so that the corresponding contact pin 2 has a signal output, that is, As long as one of the at least six contact pins 2 has a signal output, the signal processing circuit 6 can sense the direction.

The second way is that the signal processing circuit 6 replaces the power supply position (not drawn), and in the at least six contact pins 2, each of the contact pins 2 is changed to a different voltage. That is to say, the voltages connected to the contact pins 2 corresponding to different sensing directions are different.
