Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

In the related technology, the magnetic attraction type handrail is mainly installed on a base through a magnet block, an opposite piece is installed through an iron block, attraction exists between the magnet and the iron block in the rotation process of the handrail along a rotating shaft, when the handrail is closed, the iron block is close to the magnet, the magnetic attraction between the iron block and the magnet is increased, and the handrail achieves a locking function; when the armrest is opened, the armrest operating force is required to be greater than the magnetic attraction force, so that the armrest is opened. Generally, no tension is generated when the magnet and the iron or the magnet and the magnet are in complete contact, and the tension value is rapidly reduced from the maximum value to be steeply reduced in the initial stage of slow separation. When the distance reaches a certain range, the tension is approximately in direct proportion to the distance. The maximum value of the pulling force is the disengagement pulling force when the magnet is in full contact with the iron or another magnet.

Therefore, in the magnetic attraction structure of the armrest, when the armrest is closed or opened, the magnetic attraction force is suddenly increased, so that the operating force of the armrest is suddenly changed, and when the rubber pad is used for buffering, the load and deformation of the rubber pad are nonlinear, so that the sudden change of the attraction force between the magnet and the iron is difficult to smooth; meanwhile, the rubber pad is easy to age and difficult to ensure the buffer effect. Due to the two reasons, the opening or closing smoothness of the existing magnetic attraction handrail is poor.

The embodiment of the invention provides a locking mechanism of a console armrest and a vehicle, which can solve the problem that in the prior art, magnetic attraction is suddenly increased when the armrest is closed or opened in a magnetic attraction type locking mode, so that the opening or closing operation smoothness of the magnetic attraction armrest is poor.

Referring to fig. 1 and 2, a locking mechanism of a console armrest according to an embodiment of the present invention may include: the device comprises a base 1, a rotating shaft 2 is installed on the base 1, and a magnet 3 is arranged on one side, on the rotating shaft 2, of the base 1; the armrest 4 is mounted on the rotating shaft 2, the armrest 4 can rotate around the axis of the rotating shaft 2, so that the armrest 4 can be opened or closed relative to the base 1, when the armrest 4 is opened, the armrest 4 rotates around the rotating shaft 2, and the armrest 4 moves in the direction away from the magnet 3, when the armrest 4 is closed, the armrest 4 moves in the direction close to the magnet 3 around the rotating shaft 2, wherein the armrest 4 is provided with a metal block 5 matched with the magnet 3, the metal block 5 can be an iron block or other metals, and can be adsorbed with the magnet 3, when the armrest 4 is closed, the magnet 3 adsorbs the metal block 5, so that the armrest 4 is fixed, and when a certain force is applied to the armrest 4 to drive the metal block 5 to be separated from the magnet 3, the armrest 4 can be opened; and spring assemblies mounted to the armrest 4, wherein the number of spring assemblies may be one, two or more, in this embodiment, two spring assemblies are preferably provided and are symmetrically arranged with respect to the metal block 5; when the armrest 4 rotates to the magnet 3, that is, the armrest 4 is closed, so that the armrest 4 moves to the magnet 3 in a direction close to the magnet 3, the magnet 3 can gradually adsorb the metal block 5, and the spring assembly gradually contacts the base 1 in a moving process of the armrest 4, and then abuts against the base 1, so that the spring 61 is compressed.

In the embodiment, because the spring assembly is mounted on the armrest 4, when the armrest 4 rotates around the rotating shaft 2 in the closing process of the armrest 4, the opening angle of the armrest 4 is large, the distance between the magnet 3 and the metal block 5 is large, the magnetic attraction force is small, the spring 61 in the spring assembly can be in a free state, measures can be taken to enable the spring assembly to be in a compressed state when the spring assembly is not in contact with the base 1, and the spring 61 is further compressed after the spring assembly is subsequently in contact with the base 1; when the opening angle of the armrest 4 is gradually reduced, the attraction force between the magnet 3 and the metal block 5 is gradually increased, when the magnetic attraction force is suddenly increased, the spring assembly is contacted with the base 1 and is in a state of starting to enter a compression state, and the elastic force of the spring 61 can counteract a part of the magnetic attraction force, so that the phenomenon that the magnetic attraction force is too large to cause the sharp increase of the operation force can be avoided; finally, the magnet 3 and the metal block 5 are attached to each other while the spring 61 is in the maximum compression state. For the opening process of the armrest 4, the above process is reversed. Since the phenomenon that the operating force is sharply increased during the opening and closing is improved, the smoothness of the operating force of the armrest 4 is improved.

In some alternative embodiments, referring to fig. 3, the spring assembly may further include a pin 62, the pin 62 having: the main body 621 is inserted into the spring 61, and the main body 621 and the spring 61 are coaxially arranged, wherein the cross-sectional shape of the main body 621 may be various structural shapes such as a circle, an ellipse, or a diamond, and the maximum diameter of the cross-section of the main body 621 is preferably substantially equal to the inner diameter of the spring 61, so that the spring 61 can move along the surface of the main body 621 during the compression process, and the spring 61 is not easily distorted and deformed; and a stopping portion 622, which can be fixedly disposed on one side of the main body 621 close to the base 1, wherein the cross-sectional dimension of the stopping portion 622 is greater than that of the main body 621, and the stopping portion 622 is stopped at one end of the spring 61, that is, the maximum diameter of the stopping portion 622 is greater than the inner diameter of the spring 61, and the stopping portion 622 is stopped at the outer side of the spring 61, in the process of closing the armrest 4, the stopping portion 622 can directly or indirectly contact with the base 1, so that the spring 61 is compressed by the stopping portion 622, and through the arrangement of the stopping portion 622, when the stopping portion 622 initially contacts with the base 1, at least the line-to-plane contact is performed, which can increase the contact stability, and at the same time, the whole spring 61 is compressed by the stopping portion 622 to generate deformation, thereby avoiding the phenomenon of uneven stress caused by one side or a certain point of the spring 61 being compressed.

When the head cover 63 is deformed by being pressed by the base 1, the head cover 63 is compressed in the axial direction, so that the size of the head cover 63 in the radial direction is increased, and since the fixing portion 623 is provided with the plurality of buffer spaces 625, when the head cover 63 is pressed, part of the head cover 63 can enter the buffer spaces 625 in the radial direction, so that the outer contour size of the head cover 63 is not increased sharply, and further, the phenomenon that the parts on the outer side of the head cover 63 are damaged by the head cover 63 can be avoided.

Since it is quite complicated to calculate the attractive force between the magnet 3 and the metal block 5 by using a formula, the corresponding relationship between the magnetic attraction force and the distance between the magnet 3 and the metal block 5 can be determined by using a test method in practical use. As shown in fig. 4 below, the magnet 3 may be fixed, and the magnetic attraction force at different distances between the magnet 3 and the metal block 5 may be measured by using other measuring tools such as a tension meter, and when the distance between the magnet 3 and the metal block 5 is x, the magnetic attraction force may be denoted as F; several values can be measured in sequence, such as x1, F1, x2, F2, x3, F3, etc.

Since the compression stroke of the spring 61 is l-x when the distance between the magnet 3 and the metal block 5 is x, the elastic force of the spring 61 is f = k (l-x), where k is the stiffness of the spring 61 and l is the maximum operating stroke of the spring 61. For the magnetic attraction structure, when the distance between the magnet 3 and the metal block 5 is x, the operating force of the armrest 4 when opening or closing can be counted as F _{Exercise and control device} (ii) a For the magnetic attraction and spring 61 combination structure of the present invention, when the distance between the magnet 3 and the metal block 5 is x, the magnetic attraction force is opposite to the elastic force of the spring 61, and the operating force of the armrest 4 when opening or closing can be recorded as F _{Exercise and control} And (1-x) F-k. Thereby the rigidity k of the spring 61, the working stroke l, the magnetic attraction force F of the magnet 3 and the compression can be adjustedThe smoothness of the operating force of the armrest 4 is adjusted by the stroke x, so that the operating force F in the opening and closing processes is reduced _{Exercise and control} The change is too large, and the problem that the operation comfort of the handrail 4 is too poor is avoided.

When the distance x between the magnet 3 and the metal block 5 is large, and the magnetic attraction force F between the magnet 3 and the metal block 5 is small, the spring 61 does not have to be in a deformed state, i.e., F =0; as the distance x between the magnet 3 and the metal block 5 becomes smaller, the magnetic attraction force F between the magnet 3 and the metal block 5 increases exponentially, the spring 61 is in a deformed state, and as x becomes smaller, F becomes larger gradually, that is, as the magnetic attraction force between the magnet 3 and the metal block 5 becomes larger, the elastic force F of the corresponding spring 61 also increases linearly, improving the state where the operation force increases sharply. As shown in fig. 5, for different distances between the magnet 3 and the metal block 5, the magnetic attraction handrail 4 has the operation force as shown in the figure; after the magnetic attraction and spring assembly structure is adopted, the change condition of the corresponding operating force is gentle compared with the magnetic attraction structure in the related technology, so that the operating force of the handrail 4 is smoothly increased.

The embodiment of the invention also provides a vehicle which can comprise a vehicle frame and the locking mechanism of the center console armrest, which is arranged on the vehicle frame. The locking mechanism in this embodiment may adopt the locking mechanism in any of the above embodiments, and details are not described here.

According to the vehicle provided by the embodiment of the invention, the smoothness of the magnetic type armrest 4 in the opening and closing processes is adjusted by the spring assembly, so that poor operation perception caused by sudden increase and reduction of the operation force in the opening or closing process is avoided; the stroke and rigidity of the spring 61 are high in adjustment freedom, and the elastic force changes linearly, so that the spring can be quickly adjusted according to different requirements; the spring assembly is not easy to attenuate after long-term use, and the function is unchanged.
