The limiting member 30 is a rubber member, two ends of the base 10 along the sliding direction of the buffer mechanism 20 are respectively provided with a protrusion member 103, and the protrusion member 103 is sleeved with the rubber member.

The limiting member 30 is disposed to limit the buffer mechanism 20 from separating from the base 10 along the sliding direction of the buffer mechanism 20, so as to improve the reliability of the limiting connection device, and further improve the connection reliability between the first connection member 40 and the second connection member 50. The limiting member 30 is made of rubber, so that on one hand, the buffer mechanism 20 is prevented from being damaged by hard collision between the buffer mechanism 20 and the limiting member 30; on the other hand, when the external force is removed, the link member 203 can be restored to the initial position by the resilient force of the deformed rubber member, thereby eliminating the stress between the two parts. In this embodiment, the limiting member 30 is a rubber ring, and two ends of the length direction of the groove on the base 10 are provided with protruding members 103 for connecting the rubber ring, and the rubber ring is sleeved on the protruding members 103.

The limiting connection device further comprises a spring or a metal elastic sheet, one end of the spring or the metal elastic sheet is connected to the base 10, the other end of the spring or the metal elastic sheet abuts against the buffer mechanism 20, and the deformation direction of the spring or the metal elastic sheet is consistent with the sliding direction of the buffer mechanism. Wherein, set up spring or metal shrapnel in spacing connecting device to provide bigger resilience force, so that exert outside power and cancel the back, link member 203 resumes to initial position, in order to eliminate the stress between two parts, and then prevent the part deformation, or absorb the assembly tolerance of two parts in order to improve assembly efficiency. In this scheme, locating part 30 plays limiting displacement to buffer gear 20's slip, and spring or metal shrapnel provide the resilience force to buffer gear 20's reply, and the locating part is to spring or metal shrapnel's guard action, prevents that first connecting piece and second connecting piece from producing the displacement along buffer gear gliding direction too big moreover to avoid spring or metal shrapnel to take place the limit and warp and then damage spring or metal shrapnel. By adopting the structure form, the rigidity requirement on the spring or the metal elastic sheet can be reduced, so that the vibration structure required by vibration is optimized.

As shown in fig. 3 to 4, the installation process of the spacing connection device in this embodiment is as follows: the balls and the cage are pre-assembled and then loaded into the base 10, and then the link member 203 is inserted into the base 10 from above the base 10. In the process, the guide rail 2031 of the linkage 203, the balls and the slide rail 1021 of the base 10 interfere with each other, the side wall of the connecting part 102 of the base 10 deforms towards two sides, and after the base is mounted in place, the deformation disappears, and finally, the rubber parts on two sides are mounted, so that the assembly is completed. After the assembly is completed, the linkage piece 203 and the base 10 form two side slide rails, and when the linkage piece 203 slides along the length direction of the base 10, the balls roll in the slide rails to reduce the friction resistance. The number of the slide rails is at least two rows, the length of the slide rails can be increased according to design requirements, and each row of the balls is at least two and depends on the length of the slide rails.

The rubber members on both sides limit the sliding of the link member 203 in the length direction of the base 10, and the sliding stroke depends on the limit deformation amount of the rubber members. The rubber member provides a certain resilient force so that the link member 203 can return to the initial position after the external force applied along the length direction of the base 10 disappears. The magnitude of the rebound force and the sliding stroke can be changed by changing the hardness and the size of the rubber piece. The change of the elastic force of the rubber part is in a nonlinear relation with the deformation amount, the elastic force of the deformation initial section is small, and the elastic force of the deformation tail section becomes large.

It should be noted that, when the limit connection device is used in a vibration structure, the rubber only provides a limit function, and the resilience force needs to be provided by a metal elastic sheet or a spring. The rubber may be replaced by other elastomeric materials having similar properties. At the initial stage of the displacement of the first connecting piece 40 and the second connecting piece 50, the buffer mechanism slides relative to the base 10, the metal elastic sheet or the spring deforms, and at this time, the rubber piece serving as the limiting piece 30 does not deform; as the displacement between the first connecting piece 40 and the second connecting piece 50 increases, the rubber piece deforms while the metal elastic piece or the spring deforms, and the rubber piece can weaken the deformation tendency of the spring or the metal elastic piece because the elastic coefficient of the rubber piece is greater than that of the spring or the elastic piece; finally, the spring or the metal elastic sheet does not continuously deform. This is advantageous in preventing the metal dome or spring from deforming excessively, resulting in failure. The limiting connecting device with the metal elastic sheet or the spring is adopted in the vibration structure, the rigidity requirement on the metal elastic sheet or the spring can be reduced, the selection types of the metal elastic sheet, the spring and the like are wider, and the vibration structure is further optimized.

As shown in fig. 7 to 10, the process of connecting the first connecting member 40 and the second connecting member 50 by the spacing connecting device provided in this embodiment is as follows:

the first connecting member 40 and the linkage member 203 are fixed by screws, the positioning member 60 on the second connecting member 50 is inserted into the receiving cavity of the connecting portion 102, and then the second connecting member 50 and the base 10 are fixed by screws. In the process that the first connecting piece 40 and the second connecting piece 50 are connected through the limit connecting device, the first connecting piece 40 and the second connecting piece 50 can generate small-range displacement in the length direction of the limit connecting device, and in this way, the assembly tolerance of the first connecting piece 40 and the second connecting piece 50 caused by machining errors can be eliminated, so that the assembly of the two parts is facilitated, and the assembly efficiency is improved. Of course, the way of assembling the first connecting member 40 and the second connecting member 50 with the spacing connecting device is not limited to screws, and only enough connecting strength needs to be ensured.

The two positioning pins of the second connecting member 50 are inserted into the receiving cavities 1022 of the base 10, and when the linkage member 203 is subjected to an upward external force, the positioning member 60 can limit the side walls of the connecting portion 102 of the base 10 from deforming outward, so as to prevent the linkage member 203 from being removed from the base 10. When the first and second connecting members 40 and 50 are long, two means may be used, which are disposed at both ends in the length direction, respectively, and the rubber member at the inner side is eliminated.

The embodiment also provides a vehicle, which comprises the limiting connecting device, and the vehicle also comprises a first part and a second part, wherein the first part and the second part are connected through the limiting connecting device. Wherein, pass through spacing connecting device with two first parts and the second part that need have working displacement in the vehicle and connect, can effectively prevent to lead to the size of first part and second part to change because environmental changes such as temperature, external force, and then influence assembly efficiency or arouse the inefficacy scheduling problem that the stress concentration of two part junctions leads to.

The first part and the second part are not limited, and can be a vehicle-mounted screen and a screen mounting bracket, a touch panel and a panel mounting bracket, or an armrest switch and an armrest mounting bracket. For example, when the limiting connection device provided by the embodiment is used for a vehicle-mounted screen or a vibration switch, the deformation of the vehicle-mounted screen caused by the size change of the vehicle-mounted screen and an automobile instrument panel due to environmental changes such as temperature, external force and the like can be effectively prevented, and the problems of uneven display brightness, various marks and the like of the vehicle-mounted screen can be further avoided; and when the assembly is carried out, the assembly tolerance between parts is absorbed, the deformation of the vehicle-mounted screen or the vibration switch is prevented, and meanwhile, the assembly efficiency can be improved. The limiting connecting device not only can provide deformation required by vibration (realized by deformation of the metal elastic sheet or the spring and sliding of the buffer mechanism), but also has a limiting function (provided by the limiting part), so that the type selection of the metal elastic sheet or the spring is wider, and the vibration structure required by a vibration switch or a vehicle-mounted screen can be further optimized.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims.
