Description

Technical Field

[0001] The utility model relates to the technical field of seat center armrests, in particular to a locking mechanism for a center armrest in a rear seat of an automobile. Background Art

[0002] At present, the center armrest of the rear seat of a car has basically become a standard configuration. When the middle armrest is opened, it is not locked, and the middle armrest will jump up and down when the car is bumpy; when the middle armrest is closed, it is not locked, and the skin on both sides of the middle armrest and the backrest skin are squeezed together and fixed together when the car is bumpy. The middle armrest may open automatically when the car is bumpy, affecting the riding experience of the rear passengers.

[0003] For this reason, an armrest locking mechanism is proposed in a rear seat of an automobile. Summary of the Invention

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an armrest locking mechanism for a rear seat of an automobile, comprising a bracket and an armrest body, wherein two mounting plates are symmetrically mounted on the bottom of the bracket, and a support shaft is mounted on each of the two mounting plates, and a limiting groove is provided on one side of the support shaft;

[0006] The armrest body is rotatably connected to the support shaft, and a limit plate is symmetrically provided inside the armrest body, and the limit plate is adapted to the limit groove. A limit seat is installed on the inner side wall of the armrest body, and a limit rod is installed at one end of the limit plate. One end of the limit rod passes through the limit seat, and a spring is sleeved on the outer side of the limit rod.

[0007] Preferably, a plurality of guide rods are evenly mounted on one end of the limiting plate, and one end of each of the plurality of guide rods passes through the limiting seat.

[0008] Preferably, a connecting plate is installed at one end of the plurality of guide rods and the limiting rods passing through the limiting seat.

[0009] Preferably, a sliding groove is provided on the outer side of the armrest body.

[0010] Preferably, a push plate is slidably connected to the interior of the slide groove, and one side of the push plate passes through the slide groove and is connected to the limit plate.

[0011] Preferably, a support rod is installed between the two support shafts.

[0012] Compared with the prior art, the beneficial effect of the present invention is that the movable limiting plate and the limiting groove cooperate with each other to align and limit the armrest when it is opened, thereby avoiding the armrest from jumping around due to shaking and ensuring the stability of the rear armrest.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1-3 The utility model provides a technical solution: an armrest locking mechanism for a rear seat of a car, comprising a bracket 1 and an armrest body 3, two mounting plates 2 being symmetrically mounted on the bottom of the bracket 1, a support shaft 7 being mounted on each of the two mounting plates 2, and a limiting groove 8 being provided on one side of the support shaft 7;

[0019] The armrest body 3 is rotatably connected to the support shaft 7. A limit plate 9 is symmetrically provided inside the armrest body 3. The limit plate 9 is adapted to the limit groove 8. A limit seat 14 is installed on the inner side wall of the armrest body 3. A limit rod 10 is installed on one end of the limit plate 9. One end of the limit rod 10 passes through the limit seat 14. A spring 12 is sleeved on the outer side of the limit rod 10.

[0020] like Figure 3 As shown: a plurality of guide rods 11 are evenly installed on one end of the limiting plate 9, and one end of each of the guide rods 11 passes through the limiting seat 14; through the above arrangement, the guide rods 11 can perform auxiliary work when the limiting rod 10 moves, so that the limiting rod 10 can be moved more conveniently and quickly.

[0021] like Figure 3As shown: a plurality of guide rod bodies 11 and limit rod bodies 10 pass through one end of the limit seat 14 and are equipped with a connecting plate 13; through the above setting, the connecting plate 13 can limit the position of the guide rod body 11 and the limit rod body 10, thereby avoiding the situation where the guide rod body 11 and the limit rod body 10 are separated from the limit seat 14.

[0022] like Figure 1 As shown: a slide groove 4 is opened on the outside of the armrest body 3, and a push plate 5 is slidably connected to the inside of the slide groove 4. One side of the push plate 5 passes through the slide groove 4 and is connected to the limit plate 9; through the above setting, the slide groove 4 can make the push plate 5 move more conveniently, thereby driving the limit plate 9 to move and disengage it from the inside of the limit groove 8.

[0023] like Figure 2 As shown: a support rod 6 is installed between the two support shafts 7; through the above arrangement, the overall strength of the equipment is increased.

[0024] Working principle: When the armrest body 3 is opened, the armrest body 3 rotates around the support shaft 7. When the armrest body 3 is in a horizontal state, the limit plate 9 and the limit slot 8 are in the same horizontal plane, and then the limit plate 9 will be inserted into the limit slot 8 through the spring 12, thereby limiting and fixing the position of the armrest body 3, thereby preventing the armrest body 3 from rotating at will.

[0025] When the armrest body 3 needs to be folded up, the push plate 5 is pushed, and the push plate 5 drives the limit plate 9 to move, so that the limit plate 9 is disengaged from the inside of the limit groove 8, and the spring 12 is compressed at the same time. When the limit plate 9 is completely disengaged, the armrest body 3 is rotated upward, thereby limiting the position of the limit plate 9 through the outer side of the support shaft 7, so that the spring 12 is compressed for a long time, which is convenient for the next use. When the armrest body 3 is folded up, the position of the armrest body 3 can be limited by the clamping structure between the front section of the armrest body 3 and the top of the bracket 1. The clamping structure here is the existing technology and can be any structure such as cantilever clamping or annular buckle, depending on the specific situation, so it will not be repeated.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
