[0038] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] With the modernization of society, in some production practices, for the motion control of certain specific structures, people are increasingly relying on motion sensing devices. The motion sensing devices can drive the moving parts to perform preset movements. When the moving parts complete the preset movement, the motion sensing devices can stop automatically.

[0041] However, when the motion sensing device drives the moving part to perform a preset motion, the motion sensing device needs to be connected to the moving part first, and then the sensing accuracy of the motion sensing device needs to be ensured to ensure the accuracy of the moving part to achieve the preset motion.

[0042] In actual operation, when the technician connects the moving part to the motion sensing device, it is inevitable that the sensing part 32 on the motion sensing device will come into contact. As the number of contacts accumulates, the sensing part 32 itself will be damaged, or the position of the sensing part 32 in the motion sensing device will be affected, which will affect the sensing accuracy of the motion sensing device and even damage the entire motion sensing device.

[0043] In view of this, first of all, please refer to Figure 1 to Figure 2The embodiment of the present application provides a motion sensing device, which can drive the moving part to be moved, and the motion sensing device includes a base 10, a moving component 20 and a sensing component 30. The moving component 20 is movably connected to the base 10 and protrudes from the base 10 along the first direction X. The moving component 20 has an abutment surface 211 away from the base 10 in the first direction X. The moving component 20 is used to connect the moving part to be moved, and is configured so that the moving part to be moved moves synchronously, and the moving part to be moved abuts against the abutment surface 211. The sensing component 30 includes a first sensor 31 and a sensing member 32. The sensing member 32 is connected to the moving component 20. The sensing member 32 is located on the outer peripheral side of the abutment surface 211. The first sensor 31 is fixed to the base 10 and is spaced apart from the moving component 20. The first sensor 31 is used to sense the sensing member 32.

[0044] The motion sensing device provided in the embodiment of the present application can drive the moving part to realize a preset motion, wherein in different technical fields, the moving part corresponds to different structures. For example, during the installation of the automobile body, it is necessary to realize a specific motion of the automobile body, and the moving part can be a body hoist that can lift the automobile body, or the moving part can be a skid that can translate the automobile body.

[0045] The motion sensing device provided in the embodiment of the present application includes a fixed-position base 10, a motion component 20 and a sensing component 32 that can move relative to the base 10 and can move synchronously with the part to be moved, and a first sensor 31 that can sense the motion state of the motion component 20. Among them, the base 10 should be understood as a fixed-position base body, and the base 10 can be a connecting frame with a certain height, or it can be just a base body with a plate-like or block-like structure. Specifically, when the base 10 is fixed in position, the position of the first sensor 31 fixedly connected to the base 10 is fixed, the motion component 20 is movably connected to the base 10, and when the motion component 20 moves relative to the base 10, it can drive the part to be moved and the sensing component 32 to move together.

[0046] In some embodiments, the motion sensing component 30 further includes a driving member 50, which is transmission-connected to the motion component 20, and the driving member 50 can drive the motion component 20 and the sensing member 32 to move relative to the base 10. Exemplarily, the motion component 20 is slidably connected to the base 10, the driving member 50 drives the motion component 20 and the sensing member 32 to slide relative to the base 10, the motion component 20 drives the moving member and the sensing member 32 to slide, and the first sensor 31 senses the sliding of the motion component 20. Alternatively, exemplarily, the motion component 20 is rotationally connected to the base 10, the driving member 50 drives the motion component 20 and the sensing member 32 to rotate relative to the base 10, the motion component 20 drives the moving member and the sensing member 32 to rotate, and the first sensor 31 senses the rotation of the motion component 20. The first sensor 31 is electrically connected to the driving member 50, and when the first sensor 31 senses a specific signal, it sends a signal to drive the driving member 50, and the driving member 50 will start driving or stop driving. The first sensor 31 is spaced apart from the moving component 20 to form a moving space around the moving component 20 to avoid interference between the moving component 20 and the first sensor 31 .

[0047] The moving component 20 is arranged to protrude from the base 10 along the first direction X. The moving component 20 has an abutting surface 211 away from the base 10 in the first direction X. The sensing member 32 is arranged on the outer peripheral side of the abutting surface 211. The first sensor 31 can sense the sensing member 32. The moving part to be moved can be connected to the moving component 20 and abut against the abutting surface 211. The moving component 20 protrudes from the base 10 along the first direction X, so that the moving part to be moved can be connected to the moving component 20 along the first direction X.

[0048] The part to be moved and the moving assembly 20 at least include a first state and a second state. In the first state, the part to be moved and the moving assembly 20 are spaced apart in the first direction X. In the second state, the part to be moved and the moving assembly 20 are connected to each other. In the process of the part to be moved being connected to the moving assembly 20 along the first direction X, the part to be moved and the moving assembly 20 approach each other in the first direction X until the part to be moved abuts against the abutting surface 211. Since the sensing member 32 is disposed on the outer peripheral side of the abutting surface 211, the projections of the sensing member 32 and the abutting surface 211 in the first direction X do not overlap. In the process of the part to be moved being connected to the moving assembly 20, the part to be moved will not come into contact with the sensing member 32, and will not affect the sensing member 32, thereby avoiding damage to the sensing member 32 by the part to be moved and ensuring the normal operation of the sensing member 32.

[0049] In this embodiment, the sensing member 32 and the first sensor 31 are a pair of devices that can sense each other. For example, the sensing member 32 can be a magnetic object, and the first sensor 31 can be a magnetic induction sensor. The magnetic induction sensor senses the position or motion state of the magnetic object by detecting changes in the magnetic field. Alternatively, the sensing member 32 can be a specific light source, and the first sensor 31 can be a photoelectric sensor. The photoelectric sensor senses the presence or brightness of the light source by detecting changes in light. By connecting the sensing member 32 to the moving component 20, that is, the structure corresponding to the movement, and setting the first sensor 31 on the base 10, that is, the relatively fixed structure, the first sensor 31 can make a corresponding induction to the sensing member 32, so as to judge the motion state or motion position of the moving component 20, so as to enable the moving component 20 to drive the moving part to accurately complete a specific movement.

[0050] In summary, in the embodiment of the present application, the motion component 20 is movably connected to the base 10 to drive the moving part to move, and the motion state or motion position of the motion component 20 is determined by sensing the sensing part 32 through the first sensor 31, so as to achieve the overall stable operation of the motion sensing device. As for the relative positional relationship among the moving component 20, the part to be moved and the sensing component 32, the moving component 20 is protruded from the base 10 along the first direction X, and the moving component 20 has a contact surface 211 facing away from the base 10 in the first direction X. When the part to be moved is connected to the moving component 20, the part to be moved contacts the contact surface 211, and the sensing component 32 is located on the outer peripheral side of the contact surface 211. Through the above arrangement, since the sensing component 32 is arranged on the outer peripheral side of the contact surface 211, the projection of the sensing component 32 and the contact surface 211 in the first direction X does not overlap. In the process of the part to be moved being connected to the moving component 20, the part to be moved will not contact the sensing component 32 on the circumferential side of the first direction X, so as to reduce the impact on the sensing component 32, thereby reducing the probability of damage to the sensing component 32 by the part to be moved, ensuring the normal operation of the sensing component 32, and further ensuring the overall stable operation of the motion sensing device.

[0051] In some embodiments, see Figure 1 to Figure 2, the sensing member 32 is located on the side of the abutting surface 211 close to the base 10, and the abutting surface 211 and the sensing member 32 are spaced apart in the first direction X. The sensing member 32 is arranged on the side of the abutting surface 211 close to the base 10, so that the first sensor 31 fixed on the base 10 can sense the sensing member 32. The abutting surface 211 and the sensing member 32 are spaced apart in the first direction X, so that the contact between the moving part and the sensing member 32 in the first direction X can be avoided, and the influence of the moving part on the connection position of the sensing member 32 and the moving component 20 can be reduced, so as to ensure the connection stability and position stability of the sensing member 32 on the moving component 20, thereby ensuring the accurate sensing of the sensing member 32 by the first sensor 31, so as to realize the accurate control of the moving component 20.

[0052] Regarding the connection between the sensing member 32 and the moving assembly 20, in one embodiment, the sensing member 32 and the moving assembly 20 are both made of metal, and the sensing member 32 and the moving assembly 20 are fixedly connected by welding. In another embodiment, the sensing member 32 and the moving assembly 20 are also made of metal, and the sensing member 32 and the moving assembly 20 are threadedly connected.

[0053] In some embodiments, the motion component 20 includes at least a first fastening member 21, and the first fastening member 21 is movably connected to the base 10. A second fastening member 40 is provided on the moving part, and the second fastening member 40 is detachably connected to the first fastening member 21. The connection between the moving part and the motion component 20 is achieved by setting the connection structure between the first fastening member 21 and the second fastening member 40. In some embodiments, the motion component 20 also includes the remaining structure between the auxiliary first fastening member 21 and the second fastening member 40. Exemplarily, the motion component 20 also includes a fastening rib connected to the first fastening member 21 to increase the friction force after the first fastening member 21 is connected to the second fastening member 40, so as to ensure the connection strength between the first fastening member 21 and the second fastening member 40.

[0054] In the embodiment of the present application, the second clamping fixture 40 and the part to be moved may be fixedly connected or detachably connected. It should be noted that there should be at least one degree of freedom of movement restriction between the second clamping fixture 40 and the part to be moved. Exemplarily, when the synchronous movement of the second clamping fixture 40 and the part to be moved is sliding, the second clamping fixture 40 and the part to be moved should be fixed in the sliding direction; when the synchronous movement of the second clamping fixture 40 and the part to be moved is rotation, the second clamping fixture 40 and the part to be moved should be fixed in the rotation direction.

[0055] Due to the difference in the motions to be realized between the first fixing member 21 and the second fixing member 40 and the moving part, different settings can be made for the setting form and the corresponding connection form of the first fixing member 21 and the second fixing member 40. For example, when the first fixing member 21 drives the second fixing member 40 to slide together, the first fixing member 21 and the second fixing member 40 need to form a limit on both sides of the sliding direction, the first fixing member 21 and the second fixing member 40 can both be set as a plate-like structure, and corresponding connecting threaded holes are set on the first fixing member 21 and the second fixing member 40, and the first fixing member 21 and the second fixing member 40 are connected as an integral structure by bolts and nuts to realize the movement of the first fixing member 21 and the second fixing member 40 together. Exemplarily, when the first clamping fixture 21 drives the second clamping fixture 40 to rotate together, they can be connected into an integrated structure by means of a threaded connection and then rotated, or a clamping groove can be provided on the first clamping fixture 21 along its rotating circumference, and a clamping portion can be provided on the second clamping fixture 40 along its rotating circumference, and the clamping portion can be clamped in the clamping groove. The first clamping fixture 21 and the second clamping fixture 40 are connected by means of a clamping connection, so that the first clamping fixture 21 drives the second clamping fixture 40 to rotate.

[0056] In some embodiments, see Figure 1 to Figure 2 The first clamping member 21 includes a first portion 212 movably connected to the base 10 and protruding from the base 10, and a second portion 213 fixed to the first portion 212 on a side away from the base 10. The sensing member 32 is fixed to the peripheral side of the first portion 212, and the side of the second portion 213 away from the first portion 212 is recessed inward to form a recess 2131, and the abutting surface 211 includes a bottom wall structure of the recess 2131 in the first direction X.

[0057] The first fastening member 21 includes a first portion 212 and a second portion 213 connected to each other in the first direction X, and the first portion 212 is connected to the base 10. It can be understood that the first fastening member 21 is divided into two portions along the first direction X, wherein the first portion 212 is closer to the base 10 than the second portion 213, and the first portion 212 and the second portion 213 can be divided by the abutting surface 211 as a boundary.

[0058] The sensing member 32 is fixed to the circumferential side of the first portion 212, and the abutting surface 211 is located in the second portion 213, so that the sensing member 32 and the abutting surface 211 are spaced apart in the first direction X. Specifically, the side of the second portion 213 that is away from the first portion 212 is recessed inward to form a recess 2131, and the abutting surface 211 includes a bottom wall structure of the recess 2131 in the first direction X. When the second clamping member 40 is connected to the first clamping member 21, the second clamping member 40 overlaps with the recess 2131 along the first direction X. The provision of the recess 2131 enables the first clamping member 21 to form a good limiting structure for the second clamping member 40, so as to improve the connection stability between the first clamping member 21 and the second clamping member 40.

[0059] In some embodiments, see Figure 1 to Figure 2 The second portion 213 includes a first limiting portion 2132 and a second limiting portion 2133 which are arranged on both sides of the recess 2131 along the second direction Y, and the first direction X intersects with the second direction Y. The first limiting portion 2132 and the second limiting portion 2133 are arranged at intervals from each other in the second direction Y, and the recess 2131 is located between the first limiting portion 2132 and the second limiting portion 2133. When the second clamping member 40 is connected to the first clamping member 21, the second clamping member 40 can be clamped between the first limiting portion 2132 and the second limiting portion 2133. The first limiting portion 2132 and the second limiting portion 2133 are respectively located on both sides of the second clamping member 40, which can further limit the second clamping member 40 and further improve the connection stability between the second clamping member 40 and the first clamping member 21. Exemplarily, when the second clamping member 40 drives the first clamping member 21 to slide, the first limiting portion 2132 and the second limiting portion 2133 are arranged on both sides of the recess 2131 along the sliding direction to clamp the second clamping member 40 and ensure the connection stability between the second clamping member 40 and the first clamping member 21.

[0060] In some embodiments, see Figure 1 to Figure 2 The first portion 212 is rotatably connected to the base 10 around an axis parallel to the first direction X. The motion sensing device is configured such that the second clamping member 40 can penetrate into the recess 2131 and abut against at least one of the first limiting portion 2132 and the second limiting portion 2133 so that the first clamping member 21 and the second clamping member 40 rotate synchronously.

[0061] The first part 212 is connected to the base 10 and rotates around an axis parallel to the first direction X to drive the second clamping member 40 and the part to be moved to rotate. The first limiting portion 2132 and the second limiting portion 2133 are located on both sides of the recess 2131 along the second direction Y. Regardless of whether the first part 212 rotates clockwise or counterclockwise, the second part 213 can generate a stable torque on the second clamping member 40 to stably drive the second clamping member 40 and the part to be moved to rotate.

[0062] In some embodiments, see Figure 1 to Figure 2 The sensing assembly 30 further includes a second sensor 33, which is fixed to the base 10 and spaced apart from the moving assembly 20. The second sensor 33 and the first sensor 31 are spaced apart along the circumference of the moving assembly 20, and the second sensor 33 is used to sense the sensing element 32. The first sensor 31 and the second sensor 33 are located on the same circumference of the first direction X, and both the first sensor 31 and the second sensor 33 can sense the sensing element 32.

[0063] In one embodiment, the first sensor 31 is at the starting angle of the first fastening member 21, and the second sensor 33 is at the ending angle of the first fastening member 21. Both the first sensor 31 and the second sensor 33 are configured as proximity switches. For the sensing member 32, the sensing member 32 includes a sensing surface 321, and the sensing surface 321 is configured to protrude from the side of the first portion 212. Through the above configuration, when the sensing member 32 is at the corresponding angle of the first sensor 31, the distance between the sensing surface 321 and the first sensor 31 is smaller than the distance between the side of the first portion 212 and the first sensor 31, so that the first sensor 31 can clearly detect the sensing member 32. When the sensing member 32 is at the corresponding angle of the second sensor 33, the same principle applies, which will not be repeated here.

[0064] In order to avoid interference between the sensing element 32 and the first sensor 31 or the second sensor 33, the protruding distance between the sensing surface 321 and the side surface of the first portion 212 is smaller than the distance between the first portion 212 and the first sensor 31; the protruding distance between the sensing surface 321 and the side surface of the first portion 212 is smaller than the distance between the first portion 212 and the second sensor 33.

[0065] In some embodiments, the first part 212 is slidably connected to the base 10, and the sensing component 30 includes a first sensor 31 and a second sensor 33 arranged parallel to the sliding direction of the first part 212. The first sensor 31 is located at the starting position of the sliding of the first clamping member 21, and the second sensor 33 is located at the end position of the sliding of the first clamping member 21. The first sensor 31 and the second sensor 33 are both configured as proximity switches. For the sensing member 32, the sensing member 32 includes a sensing surface 321, and the sensing surface 321 is configured to protrude from the side of the first part 212. Through the above configuration, when the sensing member 32 is located at the corresponding position of the first sensor 31, the distance between the sensing surface 321 and the first sensor 31 is smaller than the distance between the side of the first part 212 and the first sensor 31, so that the first sensor 31 can accurately detect the sensing member 32. When the sensing member 32 is located at the corresponding position of the second sensor 33, the same principle applies, which will not be repeated here.

[0066] In some embodiments, see Figure 1 to Figure 2 The first position-limiting portion 2132 includes a main body and a guide portion connected to the side of the main body away from the first portion 212, and the distance between the guide portion and the second position-limiting portion 2133 in the second direction Y is greater than the distance between the main body and the second position-limiting portion 2133 in the second direction Y. When the second clamping member 40 is connected to the first clamping member 21, the second clamping member 40 is at least partially located between the main body and the second position-limiting portion 2133. The provision of the guide portion enlarges the opening of the side of the recess 2131 away from the base 10, making it easier for the second clamping member 40 to penetrate into the recess 2131.

[0067] In some embodiments, see Figure 1 to Figure 2 The first position-limiting portion 2132 includes a main body and a guide portion connected to the side of the main body away from the first portion 212, and the distance between the guide portion and the second position-limiting portion 2133 in the second direction Y is greater than the distance between the main body and the second position-limiting portion 2133 in the second direction Y; the second position-limiting portion 2133 includes a main body and a guide portion connected to the side of the main body away from the first portion 212, and the distance between the guide portion and the first position-limiting portion 2132 in the second direction Y is greater than the distance between the main body and the first position-limiting portion 2132 in the second direction Y. The main body on the first position-limiting portion 2132 and the main body on the second position-limiting portion 2133 are arranged parallel and spaced apart, the guide portion on the first position-limiting portion 2132 and the guide portion on the second position-limiting portion 2133 are arranged at an angle, and the guide portion on the first position-limiting portion 2132 and the guide portion on the second position-limiting portion 2133 are arranged obliquely in a direction away from each other.

[0068] In some embodiments, see Figure 1 to Figure 2 , the recess 2131 is arranged to penetrate the second part 213 along the third direction Z, and the first direction X, the second direction Y and the third direction Z intersect each other. The sensing member 32 is located on the side of the first limiting portion 2132 away from the recess 2131. The recess 2131 is arranged to penetrate the second part 213 along the third direction Z, so that the recess 2131 can form an opening on the side of the second part 213, so that the technicians can observe the position of the second clamping member 40 in the recess 2131, and at the same time, it is convenient for the technicians to clean the recess 2131. The sensing member 32 is located on the side of the first limiting portion 2132 away from the recess 2131, so that the setting position of the sensing member 32 on the first part 212 and the movement trend of the second clamping member 40 to connect to the first clamping member 21 can be offset, so as to prevent the second clamping member 40 from affecting the sensing member 32.

[0069] In some embodiments, the projection of the recess 2131 in a direction perpendicular to the first direction X is inside the projection of the first clamping member 21 in a direction perpendicular to the first direction X, that is, the recess 2131 does not penetrate the second part 213 along the third direction Z, and the sensing element 32 only needs to be arranged on the peripheral side of the first clamping member 21.

[0070] In some embodiments, see Figure 1 to Figure 2 The sensing member 32 and the base 10 are spaced apart in the first direction X. When the moving assembly 20 is movably connected to the base 10, the movement of the first clamping member 21 will drive the sensing member 32 to move together. Through the above arrangement, a gap can be formed between the sensing member 32 and the base 10 to avoid friction between the sensing member 32 and the base 10, thereby avoiding wear of the sensing member 32 by the base 10.

[0071] In the second aspect, an embodiment of the present application provides a motion system, which includes the above-mentioned motion sensing device and a part to be moved, the motion component 20 includes a first clamping fixture 21, the first clamping fixture 21 is movably connected to the base 10, and a second clamping fixture 40 is provided on the part to be moved, and the second clamping fixture 40 is detachably connected to the first clamping fixture 21.

[0072] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
