[0030] Reference Figure 1As shown, an embodiment of the present application discloses a cylinder mounting assembly, which includes a mounting seat 1, a cylinder 3 and an elastic member 2. The bottom of the cylinder 3 is movably connected to the mounting seat 1, so that the cylinder 3 can move relative to the mounting seat 1. One end of the elastic member 2 is connected to the cylinder 3, and the other end of the elastic member 2 is connected to the mounting seat 1. The elastic member 2 is in a stretched state and is used to apply a force to the cylinder 3 so that the cylinder 3 can remain in a first state. The first state may refer to a state in which the angle between the axial direction of the output shaft of the cylinder 3 and the line perpendicular to the mounting seat 1 is not greater than 15° when the cylinder 3 is not acting on a load. The line perpendicular to the mounting seat 1 may be, for example, Figure 1 The dotted line A in .
[0031] In order to facilitate the installation of the cylinder 3, the mounting base 1 includes a base 11 and a cylinder mounting member, the cylinder mounting member is arranged on the base 11, and the cylinder 3 is mounted on the cylinder mounting member. One end of the elastic member 2 is connected to the side of the cylinder 3, and the other end of the elastic member 2 is connected to the base 11.
[0032] In this embodiment, the cylinder mounting member can be set as a universal ball joint 12, which is mounted on the base 11, and the bottom of the cylinder 3 is assembled on the universal ball joint 12, so that the cylinder 3 can rotate with the universal ball joint 12 as the center, so that the cylinder 3 can move relative to the mounting seat 1. It can be understood that in other embodiments, the cylinder mounting member can also be set as a hinge, which is mounted on the base 11, and the cylinder 3 is connected to the hinge, so that the cylinder 3 can move relative to the mounting seat 1. Of course, the cylinder mounting member can also be set as other components, as long as it is ensured that the cylinder 3 can move relative to the mounting seat 1.
[0033] The universal joint 12 is a spherical structure, which includes a first hemispherical part 121 and a second hemispherical part 122. The second hemispherical part 122 is connected to the first hemispherical part 121, and the second hemispherical part 122 can rotate relative to the first hemispherical part 121. The cylinder 3 refers to a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The cylinder 3 usually includes a cylinder body 31 and an output shaft 32. The output shaft 32 is movably arranged on the cylinder body 31, and the output shaft 32 can be driven to perform telescopic motion under the action of the cylinder body 31.
[0034] In this embodiment, the cylinder 3 is connected to the mounting seat 1 through the universal ball joint 12, and a force is applied to the cylinder through the elastic member 2, so that the cylinder 3 can be kept in the first state, so that the cylinder 3 can slightly rotate with the universal ball joint 12 as the center, to ensure that after the cylinder is installed, its movement direction will adjust itself following the movement direction of the load it acts on, thereby keeping the movement direction of the cylinder consistent with the movement direction of the load acted on by the cylinder. Therefore, damage to the cylinder or the mounting seat can be avoided, and the requirements for cylinder installation accuracy are reduced.
[0035] Continue to refer to Figure 1As shown, there can be multiple elastic members 2, one end of each of the multiple elastic members 2 is connected to the side of the cylinder 3 to form multiple first connection points; the other ends of each of the multiple elastic members 2 are connected to the base 11 to form multiple second connection points. In this embodiment, the peripheral side of the cylinder 3 is connected to the base 11 through multiple elastic members 2, and each elastic member 2 is in a stretched state, so that a tensile force can be applied to the peripheral side of the cylinder 3 through the multiple elastic members 2 to keep the cylinder 3 in the first state, for example, the cylinder 3 is substantially perpendicular to the mounting seat 1, and can also prevent the cylinder 3 from being separated from the universal ball joint 12 during the movement.
[0036] In this embodiment, there may be multiple elastic members 2. When there are two elastic members 2, one end of the two elastic members 2 may be connected to the opposite sides of the cylinder 3, and the other end of the two elastic members 2 may be connected to the opposite sides of the base 11. When there are more than three elastic members 2, the connecting line of the cross section of each elastic member may be a polygon. It is understood that in other embodiments, there may be only one elastic member 2. When there is only one elastic member 2, the connection method may be: one end of the elastic member 2 is connected to the output shaft end of the cylinder 3, and the other end of the elastic member 2 is connected to other components.
[0037] In order to make the output shaft 32 of the cylinder 3 substantially perpendicular to the mounting seat 1 in the natural state, that is, the angle between the axial direction of the output shaft 32 of the cylinder 3 and the line perpendicular to the mounting seat 1 is approximately zero, the tension applied by each elastic member 2 to the cylinder 3 is the same, that is, when the cylinder 3 is in the natural state, if the tension applied by each elastic member 2 to the peripheral side of the cylinder 3 is the same, the cylinder 3 can be set vertically to the mounting seat 1, which is more conducive to the cylinder 3 acting on the load and the movement direction of the cylinder following the movement direction of the load it acts on to adjust itself; if the tension applied by each elastic member 2 to the peripheral side of the cylinder 3 is different, the cylinder 3 may be obviously inclined to the mounting seat 1, which may not be conducive to the cylinder 3 acting on the load and the movement direction of the cylinder following the movement direction of the load it acts on to adjust itself. Among them, the cylinder 3 is in the natural state, which means that the cylinder 3 is not acting on the load.
[0038] In this embodiment, the shortest distance between each first connection point and the bottom of the cylinder 3 is equal, and the shortest distance between each first connection point and the bottom of the cylinder 3 may be greater than or equal to half the length of the cylinder body 31 of the cylinder 3. For example, assuming that the length of the cylinder body 31 of the cylinder 3 is L, the shortest distance between each first connection point and the bottom of the cylinder 3 may be 0.5L, 0.6L, 0.7L, 0.8L, etc. In this embodiment, by making the shortest distance between each first connection point and the bottom of the cylinder 3 greater than or equal to half the length of the cylinder body 31 of the cylinder 3, the limiting effect of each elastic member 2 on the cylinder 3 can be further improved.
[0039] In this embodiment, the length extension direction of each elastic member 2 is inclined relative to the line perpendicular to the mounting seat 1, and the distance between two adjacent first connection points is smaller than the distance between two corresponding adjacent second connection points. In this embodiment, the length extension direction of each elastic member 2 is inclined relative to the line perpendicular to the mounting seat 1, thereby improving the effect of each elastic member 2 exerting a force on the cylinder 3.
[0040] In this embodiment, the elastic member 2 may be a compression spring, a rubber strip, etc., which is not limited here.
[0041] Continue to refer to Figure 1 As shown, the cylinder mounting assembly also includes a plurality of first fixing members 4 and a plurality of second fixing members 5, and the mounting seat 1 also includes a mounting member 14, which is arranged on the base 11 and is provided with a limiting groove 141, and a limiting recess 311 is provided at the bottom of the cylinder body 31, and the first hemispherical part 121 of the universal joint 12 is located in the limiting groove 141, and the second hemispherical part 122 of the universal joint 12 is located in the limiting recess 311, so that the cylinder 3 can rotate with the universal joint 12 as the center of the circle under external force. Each first fixing member 4 is arranged at intervals on the side of the cylinder body 31, and each second fixing member 5 is arranged at intervals on the base 11 and is located on the peripheral side of the mounting member 14, and the number and position of each second fixing member 5 are arranged correspondingly to the number and position of each first fixing member 4. One end of each elastic member 2 is connected to each first fixing member 4, and the other end of each elastic member 2 is connected to each second fixing member 5. At this time, each elastic member 2 is in a stretched state, so that the cylinder 3 is pulled by each elastic member 2 to prevent the cylinder 3 from being separated from the universal ball joint 12 during rotation, thereby maintaining the assembly relationship between the cylinder 3 and the universal ball joint 12.
[0042] In actual application scenarios, when there is no load, the cylinder 3 is in the middle position due to the tension of the elastic member 2. After the cylinder 3 is ventilated, the output shaft 32 of the cylinder 3 moves to the load. If the direction of movement of the output shaft 32 of the cylinder 3 is slightly deviated from the angle of the load's force surface and is not completely normal, since the elastic member 2 on the cylinder 3 is in a stretched state but not to the limit, the cylinder 3 can still change the stretched state of the elastic member 2 under stress and slightly rotate with the universal joint 12 as the center. Therefore, in the process of pushing the load to move, the cylinder 3 can be automatically adjusted to the direction of movement and the load's force surface angle completely normal under the reverse force. Among them, the normal refers to the direction of the normal line, and the normal line refers to a straight line that is always perpendicular to a plane.
[0043] The present application can ensure that the movement direction of the cylinder 3 after installation will automatically adjust itself following the movement direction of the load it acts on, so as to keep the movement direction of the cylinder 3 consistent with the movement direction of the load it acts on, thereby avoiding damage to the cylinder 3 and the mounting base 1 and greatly reducing the requirements for the installation accuracy of the cylinder 3.
[0044] Based on the above embodiment, the present application also discloses another specific implementation mode. The difference between this embodiment and the above embodiment is that, referring to Figure 2 As shown, in this embodiment, the cylinder mounting member is configured as a hinge 13 , and the cylinder 3 is connected to the base 11 via the hinge 13 , so that the cylinder 3 can move relative to the mounting seat 1 .
[0045] Specifically, the mounting member 14 is provided on the base 11, one end of the hinge 13 is connected to the mounting member 14, and the other end of the hinge 13 is connected to the cylinder 3, so that the cylinder 3 can move relative to the mounting seat 1 under the condition of external force. The first fixing members 4 are arranged at intervals on the side of the cylinder body 31, and the second fixing members 5 are arranged at intervals on the base 11 and located on the peripheral side of the mounting member 14, and the number and position of the second fixing members 5 are arranged corresponding to the number and position of the first fixing members 4. One end of each elastic member 2 is connected to each first fixing member 4, and the other end of each elastic member 2 is connected to each second fixing member 5, and at this time, each elastic member 2 is in a stretched state, so that the cylinder 3 is exerted with tension through each elastic member 2, so that the cylinder remains in the first state.
[0046] Based on the above embodiment, the present application also discloses another specific implementation mode. The difference between this embodiment and the above embodiment 1 is that, referring to Figure 2 As shown, in this embodiment, at least two elastic members 2 are provided, and the lines connecting the first connection points formed by connecting the elastic members 2 with the cylinder 3 form a first figure, and the lines connecting the second connection points formed by connecting the elastic members 2 with the mounting seat 1 form a second figure. Figure 2 The projection of the first figure completely falls within the projection of the second figure. For example, if there are two elastic members 2, the first figure composed of the lines connecting the first connection points is a straight line, and the second figure composed of the lines connecting the second connection points is also a straight line. If there are three or more elastic members 2, the first figure composed of the lines connecting the first connection points is a polygon, and the second figure composed of the lines connecting the second connection points is also a polygon. This embodiment ensures the stability of the assembly of the cylinder 3 and the cylinder mounting member by making the projection of the first figure composed of the lines connecting the first connection points on the axial direction of the output shaft 32 of the cylinder 3 completely fall within the projection of the second figure composed of the lines connecting the second connection points.
[0047] Further, among the plurality of first connection points, the spacing between two adjacent first connection points is equal, and among the plurality of second connection points, the spacing between two adjacent second connection points is equal, that is, the first connection points are evenly spaced and distributed on the side of the cylinder 3, and the second connection points are evenly spaced and distributed on the mounting seat 1. Exemplarily, if there are two elastic members 2, the first figure formed by the connection lines of the first connection points is a straight line, if there are three elastic members 2, the first figure formed by the connection lines of the first connection points is an equilateral triangle, and the second figure formed by the connection lines of the second connection points is also an equilateral triangle; if there are four elastic members 2, the first figure formed by the connection lines of the first connection points can be a square, and the second figure formed by the connection lines of the second connection points can also be a square.
[0048] The following describes the corresponding features by taking the case where there are three or more elastic members 2 as an example. When there are three or more elastic members 2, the cross sections of the elastic members 2 are connected to form a polygon. Figure 2 The plane obtained by cutting each elastic member from a plane parallel to the Y direction and the Z direction. Exemplarily, if there are three elastic members 2, the first figure formed by the lines connecting the first connection points is a triangle, and the second figure formed by the lines connecting the second connection points is also a triangle; if there are four elastic members 2, the first figure formed by the lines connecting the first connection points can be a quadrilateral, and the second figure formed by the lines connecting the second connection points can also be a quadrilateral.
[0049] In this embodiment, the projection area of the first figure in the direction perpendicular to the mounting seat 1 is smaller than the projection area of the second figure in the direction perpendicular to the mounting seat 1, and the area of the figure formed by the connecting lines of the cross sections of the elastic members 2 gradually increases along the direction of the cylinder 3 pointing to the mounting seat 1, that is, this embodiment further ensures the stability of the assembly of the cylinder 3 and the cylinder mounting member by gradually increasing the area of the figure formed by the connecting lines of the cross sections of the elastic members 2. Because, if the elastic members 2 are arranged in a direction parallel to the mounting seat 1, the assembly effect of the cylinder 3 and the cylinder mounting member may be poor.
[0050] In some embodiments, reference Figure 3 As shown, there are four elastic members 2, and the four elastic members 2 are connected to the side of the cylinder 3 at equal intervals to form four first connection points. The four first connection points are located at the four corners of the cylinder 3, so that the connection lines of the four first connection points form a square. The four elastic members 2 are also connected to the mounting seat 1 at equal intervals to form four second connection points, and the connection lines of the four second connection points also form a square. It can be understood that in other embodiments, the elastic members 2 can also be provided with five, six or more than six, and correspondingly, the connection lines of the cross sections of the elastic members 2 can also form a pentagon, a hexagon or more than hexagons.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application is described in detail with reference to the above embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
