Description

Technical Field

[0001] The invention belongs to the field of automobile parts, and in particular relates to a wrench system and a car cover with the wrench system. Background Art

[0002] A pickup truck is a vehicle that has a sedan front and cab, and an open truck compartment. It has the characteristics of having the comfort of a sedan while maintaining strong power. Its ability to carry more cargo and adapt to rough roads is stronger than that of a sedan. It is an important part of the automobile market.

[0003] The cargo box of current pickup trucks is empty, which has certain defects and has no anti-theft function or rainproof function. In order to have certain anti-theft and rainproof functions, a hood is usually added to the cargo box. However, the current hoods are of fixed size during production, and a hood is specially designed for a certain type of vehicle. If the vehicle is changed, the hood is usually unusable. The main point that causes the poor versatility of the hood here is that the locking mechanism (the wrench system in this application) cannot be adjusted according to the width of the cargo box.

[0004] For example, the published patent CN201720849758.1 discloses a pickup truck compartment cover, which has a locking mechanism that cannot be adjusted according to the width of the cargo box and has poor overall versatility. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a wrench system and a car hood with the wrench system, which solves the problem that the existing car hoods cannot adapt to a variety of car models.

[0041] Since the wrench system adjustment block 702 is provided with a plurality of slider guide grooves 7024 , the ball screw 703 is connected to different slider guide grooves 7024 according to different widths of the vehicle hood, so that the wrench system 7 can adapt to vehicle hoods of different sizes, thereby improving the application range of the wrench system 7 .

[0042] Embodiment 2:

[0043] On the basis of Example 1, each of the wrench system adjustment blocks 702 is provided with four slider guide grooves 7024, and the four slider guide grooves 7024 are arranged in parallel. When in use, the ball screw 703 selects one of the slider guide grooves 7024 to connect, and the ball screws 703 on both sides are symmetrically connected, that is, the two ball screws 703 are connected to the outermost slider guide groove 7024 or the two ball screws 703 are connected to the innermost slider guide groove 7024, so that the hood can be ensured to be located in the middle of the vehicle body and the hood can be prevented from shifting to one side.

[0044] Embodiment 3:

When the hood needs to be opened, the ball screw 703 is located at the slider limit protrusion 7023 on the other side and is engaged.

[0049] Since the slider limiting protrusion 7023 is located in the slider guide groove 7024, the spacing of the slider guide groove 7024 becomes smaller. When the limiting portion 7032 slides to correspond to the slider limiting protrusion 7023, the slider limiting protrusion 7023 just clamps the limiting portion 7032.
