It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
First, the hood lock 100 according to the embodiment of the present invention will be described in detail with reference to fig. 1 to 16.
As shown in fig. 1-16, the hood lock 100 includes a first lock body 110, a second lock body 120, a first lock 130, a second lock 140, and a cable 150.
Wherein the first lock body 110 is adapted to be connected to a bonnet, the second lock body 120 is connected to the first lock body 110, the first lock 130 is adapted to be connected to a vehicle body, the second lock 140 is adapted to be connected to the vehicle body, and the first lock 130 is adapted to be locked with the first lock body 110 and the second lock 140 is adapted to be locked with the second lock body 120. It is understood that the hood is locked to the vehicle body by the hood lock 100 when the first lock 130 is locked with the first lock body 110 or the second lock 140 is locked with the second lock body 120, and optionally, the second lock 140 is not locked with the second lock body 120 when the first lock 130 is locked with the first lock body 110.
The cable 150 is connected to the first lock 130 for driving the first lock 130 to be unlocked from the first lock body 110, and the second lock body 120 is configured to move to a position locked to the second lock 140 and connected to the cable 150 when the first lock 130 is unlocked from the first lock body 110, and the cable 150 is adapted to drive the second lock 140 to be unlocked from the second lock body 120 when the cable 150 is connected to the second lock body 120.
It is understood that the cable 150 may be connected to an operation key provided in a cab of the vehicle, and the operation of pulling the cable 150 may be performed by controlling the operation key. Pulling the cable 150 can drive the first lock 130 to unlock the first lock 110, when the first lock 130 is unlocked from the first lock 110, the second lock 120 moves to a position where the second lock 140 is locked, and the second lock 120 is connected to the cable 150 at the position, pulling the cable 150 again, and the cable 150 can drive the second lock 120 to move so as to unlock the second lock 140 from the second lock 120, that is, the cable 150 can also drive the second lock 120 to unlock the second lock 120.
It should be noted that, when the first lock 130 is unlocked from the first lock body 110, the second lock body 120 may be connected to the cable 150 in various ways, either directly or indirectly.
For example, when the cable 150 is pulled to unlock the first lock 130 from the first lock body 110, a portion of the cable 150 may just move to a position directly connected to the second lock body 120; or the pull cable 150 may be directly connected to the second lock body 120 all the time, when the pull cable 150 is pulled to unlock the first lock 130 and the first lock body 110, the pull cable 150 just drives the second lock body 120 to rotate to a position suitable for being locked with the second lock 140, and the pull cable 150 is pulled again to continue to move the second lock body 120, so that the second lock body 120 and the second lock 140 can be unlocked; or when the cable 150 is pulled to unlock the first lock 130 from the first lock 110, the second lock 120 moves to a position suitable for coupling with the first lock 130, and the cable 150 is indirectly coupled with the second lock 120 through the first lock 130.
According to the hood lock 100 provided by the embodiment of the invention, by arranging the second lock body 120 and the pull rope 150 in the structural form, the hood lock 100 can be completely unlocked by pulling the pull rope 150, that is, a user can complete the operation of opening the hood in a cab, the user does not need to touch an unlocking handle with heavy oil stains, the operation is convenient, a vehicle manufacturer does not need to develop different unlocking handles according to different vehicle types, the development cycle of the vehicle is short, and the cost is low.
