Description

A seat cover for a large seat of a non-enclosed car body

technical field

The utility model relates to a vehicle accessory, in particular to a vehicle seat cover for a large vehicle seat with a non-closed vehicle body.

Background technique

Among the existing means of transportation, land vehicles such as bicycles, motorcycles, motorcycles, tricycles, ATVs and go-karts, and even water transportation such as water motorboats, have a common feature that the driver's driving space is an open space. . Different from the enclosed driving space of a car, the body of a vehicle in which the driver's driving space is an open space can also be called a non-enclosed vehicle body.

Vehicles with non-enclosed bodies are generally equipped with car seats for drivers. Since the driving space is open, the car seats are exposed to the outdoor environment for a long time, so they are easily affected by various external adverse factors. Being in the outdoor environment for a long time, it is easy to be exposed to the scorching sun, which accelerates the aging of the car seat. It brings inconvenience to the driver; in the outdoor environment for a long time, it is easy to accumulate dust or be contaminated with other dirt, which affects the normal use of the driver.

The seats of bicycles, motorcycles, etc. are small seats of non-closed car bodies, while the seats of motorcycles, go-karts, and ATVs are large seats of non-closed car bodies. The prior art has only considered the protection of the seat cushions of small seats such as bicycles and motorcycles, but has not considered the protection of large seats such as motorcycles, ATVs and go-karts.

Detailed ways

In order to illustrate the utility model more clearly, the utility model will be specifically described below in conjunction with the accompanying drawings and specific embodiments. In the embodiment, the position where the seat cover 4 covers the seat 5 is defined as the initial position, and the position where the seat cover is located in the riding state is defined as the riding position. Replace vehicles with large seats such as motorcycles, ATVs, and go-karts with motorcycles.

Example 1

As shown in FIG. 1 , FIG. 2 and FIG. 3 , a seat cover of a large vehicle seat with a non-closed vehicle body includes a fixing part 1 , a bracket 2 , a hinge device 3 and a seat cover 4 . The fixing part 1 and the bracket 2 are two groups which are arranged on both sides of the vehicle seat 5, each fixing part 1 is detachably corresponding to the tail part of the rod part 6 set on the same side of the vehicle body 8, and the lower end of the bracket 2 is fixed on the (Welding, etc.) On the same side of the fixture 1, the seat cover 4 is connected to the upper ends of the two supports 2 by means of the hinge device 3, which can be flipped back and forth. The fixing part 1 includes a clamp 11 and an adapted fastening bolt 12 , the tightness of the fastening bolt 12 is adjusted, and the inner diameter of the clamp 11 is adjusted.

Slot 318, the second spring 372 is sleeved outside the locking pin 37, one end of the second spring 372 is fixed on the sleeve wall 351, and the other end can drive the locking pin 37 to repeatedly insert and withdraw from the locking slot 318 and be connected to the lock. On the stop pin 37, the outer end of the lock pin 37 is provided with a protrusion 371, the bottom of the triangular plectrum 38 is connected to the lock core 391, and the bottom of a hypotenuse 381 of the triangular plectrum 38 is arranged obliquely outwards. In the locked state, The upper part of the hypotenuse 381 is clamped on the inner end of the protrusion 371. In the unlocked state, the triangular pick 38 gradually rises, and the hypotenuse 381 clamps the inner end of the protrusion 371, driving the locking pin 37 to exit the locking groove.

The hood lock 39 is preferably in the form of a tumbler lock. When the key 7 is inserted to open the hood lock 39, the lock cylinder 391 of the hood lock 39 rotates and pushes the triangular pick 38 to rise, driving the locking bolt 37 to move backwards and leave the locking hole, and pull out When the key 7 is released, the triangular pick 38 descends, and the locking pin 37 is inserted into the locking groove 318 under the action of the second spring 372 , thereby locking the seat cover 4 .

When the cover lock 39 is opened, the button 34 is pressed and the outer end 321 of the return spring 32 is pushed out of the through hole, and the seat cover 4 can be turned over.

The top of the seat cover 4 is provided with a strip-shaped protruding edge 46 to prevent others from directly sitting on the seat cover 4 from damaging the seat cover.
