Embodiment 1

[0030] Embodiment 1: as figure 1 As shown, a small table board for automobiles controlled by a single motor and a screw rod, including a table board 1 and a rear structural board 2, and a symmetrical right structural board 3 and a left structural board 4 are fixedly connected to both sides of the rear structural board 2 There are symmetrical chute 5 on the inner surface of the right structural plate 3 and the left structural plate 4, the chute includes a vertical straight groove 51 at the lower end and an arc-shaped groove 52 curved forward and upward at the upper end, the arc-shaped groove 52 is divided into quarters One arc structure, the center line of the upper end is connected with the horizontal tangent, the center line of the lower end is connected with the vertical tangent, and the tail end of the arc groove 52 is connected with a small section of horizontal groove. The both sides of table board 1 rear end have bearing pin-6 and the arc groove 52 of both sides to slide...

Embodiment 2

[0036] Embodiment 2: The screw rod 17 is a double-ended or triple-ended threaded screw rod. Under the condition of the same pitch, the feed speed of double or triple threads can be multiplied according to the number of threads. All the other structures are with embodiment 1.

[0037] The key facilities of the device include arc-shaped grooves 52 for guiding and supporting and fixing, so only a single motor can realize many actions of table board rising, extending, turning over and horizontal fixing, with complete functions and self-locking function. For the table top 1, it is also a feature that this structural scheme is different from the prior art by setting the main support point at the middle part of the table board instead of the rear end; The special multi-head screw fast transmission is a major advantage of this structural scheme.

Embodiment 3

[0038] Embodiment 3: the upper end of the support arm 12 is hinged with the middle part of the lower side of the table plate through the hinge support 11, and the lower end of the support arm 12 is fixedly connected to the support arm slideway on the front side of the table plate drive plate 8 through the slideway connector 13 14 slip fit. All the other structures are with embodiment 1. see Figure 7 .

Abstract

The invention discloses an automotive small table plate controlled by a single motor and a lead screw. The automotive small table plate controlled by the single motor and the lead screw comprises a table plate body and front, back, left and right structural plates, chutes are formed in the inner side surfaces of the left and right structural plates, each chute comprises an arc-shaped groove at theupper end, hinge pins are arranged on two sides of the rear end of the table plate body and are in sliding fit with the arc-shaped grooves, the middle of the rear end of the table plate body is hinged to the upper end of a table plate connecting plate, the middle of the lower end of the table plate body is hinged to the upper end of a table plate driving plate, and hinge pins at the lower ends oftwo sides of the table plate connecting plate and pins at the lower ends of the two sides of the table plate driving plate are in sliding fit with the chutes; a hinged support is arranged on the front side surface of the table plate driving plate and is hinged to a supporting arm, and the upper end of the supporting arm is in sliding fit with a supporting arm slide on the lower side surface of the table plate body; the rear side surface of the table plate driving plate is fixedly connected with a lead screw nut through a connecting arm; the lead screw nut is matched with a lead screw; and theupper end of the lead screw is matched with an upper bearing fixing block and a bearing in an upper bearing block, and is provided with an upper limiting rubber ring; and a journal at the lower end of the lead screw is matched with a lower bearing block fixing block and a bearing in a lower bearing block, a lower limiting rubber ring is arranged on the upper side surface of the lower bearing block fixing block of the lead screw, and the lower end of the lead screw is connected with a motor.

Description

technical field [0001] The invention belongs to the technical field of automobile accessories, and in particular relates to an electric table structure for automobiles. Background technique [0002] The car table structure in the prior art generally adopts a manual operation scheme or an electric scheme driven by multiple motors. Some transmission mechanisms using electric schemes use rack and pinion transmission, some use synchronous belt transmission, some use linkage mechanism transmission, or a mixture of several schemes. Correspondingly, the number of parts is large, and the structure and operation are more complicated. , and the introduction of multiple motors and their supporting control links will increase the requirements for installation space and increase the failure rate. [0003] For example, Patent No. 201610604688, the patent titled "Automatic Rollover Electric Table for Central Armrest of Automobile and Turning Method", has the above-mentioned defects. In or...
