The present disclosure relates to the technical field of vehicle equipment, and in particular to a clamping device, and a method for determining a curve of a stroke curve protrusion in a clamping device.
With the development of automobile industry and the improvement of people's living standards, more and more families own private cars.

S101 Determining a first distance required by the clamping assembly when the first drive assembly moves from a second position to an end position.
When the first drive assembly is at the second position, the ratchet component and the ratchet wheel change from a separated state to an engaged state, and in the process of moving from the second position to the end position, the first drive assembly drives the ratchet wheel and the rotating plate to rotate synchronously, and drives the clamping assemblies to move towards each other via the connecting rod (retracting relative to the mounting base).
The first distance is a distance preset by the user, i.e. the user wants to control the retraction distance of the clamping assembly relative to the mounting base during the movement of the first drive assembly from the second position to the end position, the first distance being a constant value.
S102 Acquiring a length of the connecting rod.
S103 Acquiring a second distance between a first end of the connecting rod and a rotation center point of the rotating plate and a first included angle between a first connecting line and a second connecting line when the clamping assembly is at each sampling position, where the first connecting line is a connecting line between the second end of the connecting rod and the rotation center point of the rotating plate, and the second line is a connecting line between the first end of the connecting rod and the rotation center point of the rotating plate.
The sampling position of the clamping assembly refers to the position of the clamping assembly relative to the mounting base, and each sampling position corresponds to a position where the ratchet component and the ratchet wheel are engaged; when the sampling positions of the clamping assembly are different, the engaging positions of the ratchet component and the ratchet wheel are different; therefore, different sampling positions of the ratchet module need to be acquired to solve different engaging positions of the ratchet component and the ratchet wheel.
S104 Calculating a rotation angle required by the rotating plate when the clamping assembly is at each sampling position according to the first distance, the length of the connecting rod, the second distance and the first included angle.
The interconnection points among the connecting rod, the clamping assembly and the rotating plate may form a triangle, where the length of the connecting rod and the second distance are two sides of the triangle, and the first included angle is one included angle of the triangle, and the other side of the triangle, as well as the other two included angles, can be solved by the sine trigonometric function formula a/sin<A=b/sin<B=c/sin<C.
After retracting the clamping assembly by the first distance, a new triangle will be formed, by using the sine trigonometric function formula or cosine trigonometric function formula: a2=b2+c2−2bc cosA, b2=a2+c2−2ac cosB, c2=a2+b2−2bc cosC, the length and included angle of each side of the new triangle can be obtained, so that the required rotation angle of the rotating plate can be calculated.
S105 Determining the curve of the stroke curve protrusion according to the rotation angle required to rotate the plate when the clamping assembly is in each sampling position.
When the clamping assembly is at different sampling positions, the corresponding rotation angles are also different; after the rotation angle obtained by reversely rotating the first drive assembly from the end position, the position where the ratchet component engages with the ratchet wheel is a second position, and the curves where several second positions are located are curves where the stroke curve protrusion is located.

A mapper 951 is configured to map each of the sampling positions onto the rotating plate; a calculator 952 is configured to calculate a required distance between the ratchet wheel and the ratchet component according to a rotation angle required to rotate the plate when the clamping assembly is in each sampling position; and a determiner 953 is configured to determine the stroke curve protrusion according to the required distance between the ratchet wheel and ratchet component when the clamping assembly is in each sampling position.
The present disclosure also provides an embodiment of a computing apparatus 200, see
The memory 202 is a non-volatile or non-transitory computer-readable storage medium that may be used to store a non-volatile software program, a non-volatile computer-executable program, and modules, such as program instructions/modules corresponding to a method for determining a curve of a stroke curve protrusion of a clamping device in an embodiment of the present disclosure, such as the modules shown in
The memory 202 may include a program storage area and a data storage area, where the program storage area may store an operating system and an application program required by at least one function; the data storage area may store data or the like created from the use of a device that determines the curve of the stroke curve in the clamping device. The memory 202 may include a high-speed random access memory and may also include a non-volatile memory, such as at least one magnetic disk storage apparatus, flash memory apparatus, or other non-volatile solid state storage apparatuses. In some embodiments, the memory 202 may optionally include memory remotely located relative to the processor 201, which may be connected via a network to a device for determining the curve of the stroke curve protrusion of the clamping device. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.
The one or more modules are stored in the memory 202 and, when executed by the one or more processors 201, perform a method for determining the curve on which the curve of the stroke curve of the clamping device is located in any of the method embodiments described above, e.g. perform the method steps of
The above-mentioned product can execute the method provided in the embodiment of the present disclosure, and has corresponding functional modules and advantageous effects for executing the method. For the technical details not described in detail in the embodiment, reference can be made to the method provided in the embodiment of the present disclosure.
Embodiments of the present disclosure also provide a non-volatile computer-readable storage medium having stored thereon computer-executable instructions that are executed by one or more processors, e.g. to perform the method steps of determining a curve on which a curve of travel of a clamping device is projected described above with respect to
Embodiments of the present disclosure also provide a computer program product including a computer program stored on a non-volatile computer readable storage medium, the computer program including program instructions which, when executed by a computer, cause the computer to perform a method for determining a curve of a stroke curve protrusion in a clamping device in any of the method embodiments described above, for example, performing the method steps of
The above description is only a particular embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto, and changes or substitutions thereof will readily occur to a person skilled in the art within the scope of the present disclosure, and these are intended to be within the scope of protection of the present disclosure. Therefore, the scope of protection of this application should be determined by the scope of protection of the claims.
