The utility model provides a horizontal fixing base of vehicle-mounted support.

In the embodiment of the present invention, as shown in fig. 1, in order to satisfy the requirement that the passenger in the back row of the car uses the electronic device 200 in a fixed manner, the horizontal fixing seat 100 of the car-mounted bracket extends into between two supporting rods 500 of the headrest 400 with fixed width of the car seat 300, and the clamping grooves (31, 51) at both ends are respectively clamped and fixed with the two supporting rods 500.

Specifically, referring to fig. 2-5, 10-12, 15 and 16, the transverse fixing base 100 of the vehicle-mounted bracket includes a base 10, two retaining members (30, 50) and a telescopic mechanism 70, wherein:

the seat body 10 is provided with a connecting structure 11, the two clamping pieces (30, 50) are respectively arranged at two sides of the seat body 10 along a first axis, and at least one of the two clamping pieces (30, 50) is in sliding fit with the seat body 10 along the first axis;

the outer ends of the two clamping pieces (30, 50) are respectively provided with a clamping groove (31, 51), and the openings of the clamping grooves (31, 51) of the two clamping pieces (30, 50) are arranged oppositely;

the telescoping mechanism 70 is mounted on the base body 10 and connected with the slidable catches (30, 50) to drive the corresponding catches (30, 50) at least outwardly;

the telescopic mechanism 70 and the moving space thereof are both positioned outside the projection area of the clamping grooves (31, 51) along the first axis, and the clamping grooves (31, 51) are the clamping grooves (31, 51) of the clamping pieces (30, 50) correspondingly connected with the telescopic mechanism 70.

In the present embodiment, the seat body 10 is a relatively fixed component and serves as an intermediate connection, and the connection structure 11 on the seat body 10 is used for connecting with the supporting arm of the vehicle-mounted support and even directly connecting with the portable electronic device 200. For convenience of connection, the connection structure 11 may be or include a protrusion structure or a groove structure to facilitate the insertion and fixation of the object to be connected, or may even be a simple plane structure to facilitate the absorption and fixation of the object to be connected.

For convenience of clamping, the two clamping pieces (30, 50) only need to slide relative to the seat body 10, for example, one clamping piece (30, 50) is fixed relative to the seat body 10, and the other clamping piece (30, 50) can be in sliding fit with the seat body 10 along the first axis; for another example, one of the retainers (30, 50) is rotatably connected to the base 10, and the other retainer (30, 50) is slidably engaged with the base 10 along the first axis. To facilitate sliding engagement with the base 10, the retaining members (30, 50) can be simple rods or sleeves, for example, the base 10 is a hollow structure with two open ends, and the retaining members (30, 50) slidable along the first axis can be slidably engaged with the inner cavity of the base 10.

For example, the telescoping mechanism 70 may include an elastic member for driving the movement of the retaining members (30, 50) using elastic potential energy. For example, the telescopic structure drives the clamping pieces (30, 50) to move through a gear rack, and a screw rod nut is matched with the auxiliary driving clamping pieces. Of course, in order to simplify the system complexity, it is preferable to drive the movement of the catches (30, 50) only with compression springs.

The utility model discloses two card are held in the horizontal fixing base 100 of on-vehicle support and are held the extending direction of piece (30, 50) promptly for the first axis, through holding the skew mobilizable draw-in groove (31, 51) of holding piece (30, 50) with telescopic machanism 70 and its activity space projection area on the first axis to be unlikely to occupy this card and hold the activity space of piece (30, 50), the opening of draw-in groove (31, 51) can be accomplished littleer to the connection structure 11's of pedestal 10 distance, and then can more easily will the utility model discloses a horizontal fixing base 100 stretches into in advance between two bracing pieces 500 of car seat 300 headrest 400, makes things convenient for draw-in groove (31, 51) further and the bracing piece 500 joint that corresponds.

Further, referring to fig. 6 to 9 and fig. 13, the two retaining members (30, 50) are a first retaining member 30 and a second retaining member 50, respectively, at least the first retaining member 30 is a hollow structure, the first retaining member 30 is slidably sleeved on the periphery of the seat body 10 along the first axis, and the telescopic mechanism 70 is installed in the seat body 10.

In the present embodiment, the first retaining member 30 has no direction limitation, and in a specific example, the extending direction of the first axis coincides with the left-right direction, and the first retaining member 30 can be located on either the left side or the right side. The first clamping member 30 is slidably engaged with the base 10 in a manner of being sleeved on the periphery of the base 10, so as to ensure the sliding stability and prevent the first clamping member 30 from loosening during the sliding process. As for the second retaining member 50, it may also be a hollow structure, but it is not necessarily sleeved on the periphery of the seat body 10, for example, the outer side surface of the second retaining member 50 may be matched with the inner wall surface of the inner cavity of the seat body 10, and the matching may also be slidable along the first axis. The retractable mechanism 70 is installed in the seat body 10, so that the design effect of compact structure can be achieved, and meanwhile, the retractable mechanism 70 is prevented from being interfered by external objects, i.e., the seat body 10 and/or the first clamping member 30 can provide a protection function for the retractable mechanism 70.

Further, the outer end of the first clamping member 30 is formed with a first clamping arm 32 and a second clamping arm 33 which are arranged at intervals on the second axis, and the clamping groove (31, 51) of the first clamping member 30 is formed between the first clamping arm 32 and the second clamping arm 33;

In this embodiment, the length of the second clamping arm 33 is greater than the length of the first clamping arm 32, and the extra position of the second clamping arm 33 can provide an extra moving space for the moving part of the telescopic mechanism 70, that is, an extra driving stroke can be provided on the second axis, so as to conveniently expand the application range of the lateral supporting width of the lateral fixing base 100.

Further, a first tenon 12 and a second tenon 13 are formed at one end of the seat body 10 sleeved with the first clamping member 30, the first tenon 12 is slidably sleeved with the first clamping arm 32, and the second tenon 13 is slidably sleeved with the second clamping arm 33.

In the embodiment, by providing the first tenon 12 and the second tenon 13 at the same time, when the first retaining member 30 moves outward to a larger distance, the first retaining member can also be reliably slidably engaged with the seat body 10, so as to prevent the first retaining member 30 from loosening or tilting.

Further, referring to fig. 17-20, in an embodiment, two opposite inner wall surfaces of the inner cavity of the first clamping arm 32 on the third axis are respectively provided with a first sliding protrusion 321, and two opposite inner wall surfaces of the second clamping arm 33 on the third axis are respectively provided with a second sliding protrusion 331;

In this embodiment, since the second clamping arm 33 is closer to the motive force position of the yawing moment, the number of the second sliding protrusions 331 on the second clamping arm 33 is increased, which is beneficial to more effectively balancing the yawing moment. In addition, at the same time, the first stopping protrusion 332 is matched with the second stopping protrusion 16, so that the first clamping member 30 can not be loosened from the seat body 10 when sliding to the outer end for the maximum and preset distance; moreover, because the two second sliding grooves 15 are formed on two sides of the second stopping protrusion 16, in other words, the wall surface of the second sliding groove 15 is formed on the second stopping protrusion 16, so that the second stopping protrusion 16 is reused to avoid additionally forming a channel matched with the second sliding protrusion 331, and only one protruding strip matched with the second stopping protrusion 16 needs to be arranged on the surface of the seat body 10.
