Description

Technical Field

[0001] This utility model relates to the field of automotive auxiliary device technology, and in particular to a car hood opening mechanism that does not require passengers to enter the cabin. Background Technology

[0002] In the process of automobile production, testing, and repair, it is often necessary to frequently open the vehicle's hood for inspection, adjustment, or maintenance. For example, the hood needs to be closed during transportation, while functional testing and maintenance on the transport line require it to be opened. Traditional hood opening methods typically rely on the driver entering the cab to operate an internal handle, which, via a cable-driven mechanism, unlocks the hood lock, allowing the hood to be manually lifted from the outside. However, in actual operation on production lines or repair bays, this method presents numerous inconveniences. Operators must repeatedly enter and exit the cab, which is not only inefficient but also increases labor intensity, especially on continuous, high-paced production lines, severely impacting work rhythm and overall efficiency.

[0003] In order to solve the above-mentioned technical problems, this utility model designs a car hood opening mechanism that does not require passengers to enter the cabin. Utility Model Content

[0004] This utility model provides a non-entry-to-the-cabin-side automobile hood opening mechanism, aiming to solve the problem of low efficiency and high labor intensity in opening the hood during automobile production, testing, and maintenance processes, which requires repeated entry into the driver's cabin. The technical solution is as follows: A no-entry-door car hood opening mechanism includes a fixed base, a cam disc, and a push rod. The fixed base has a receiving cavity for accommodating the cam disc. The cam disc is rotatably connected to the receiving cavity and has a working part. The fixed base also has a push rod cavity communicating with the receiving cavity. The side of the push rod cavity has an opening, and the push rod passes through the opening and slides axially along the opening. One end of the push rod is connected to the hood lock lever, and the other end extends into the receiving cavity. The push rod in the receiving cavity is located on the movement trajectory of the working part of the cam disc. The cam disc is connected to an operating unit for driving the cam disc to rotate. When the cam disc is driven to rotate by the operating unit, the working part of the cam disc can push the push rod to move axially, thereby driving the lever to move and open the hood lock.

[0005] Based on the above technical solution, a limiting post is fixedly connected inside the receiving cavity, and a sliding groove is provided on the cam disk. The limiting post is inserted into the sliding groove and can slide within the sliding groove.

[0006] Preferably, the operating unit is a movable handle fixed to the cam disk, and a pull wire is connected to the movable handle.

[0007] Preferably, the bottom of the fixing base is provided with a magnet for attracting and fixing the opening mechanism to the metal surface of the vehicle body.

[0008] Preferably, the bottom of the fixing seat is provided with a raised step for engaging with the hole in the vehicle body.

[0009] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up an operating unit on the external opening mechanism, operators can remotely open the hood without entering the cab, avoiding the tedious action of repeatedly entering and exiting the vehicle. It is suitable for scenarios requiring high-frequency operation, such as production lines and testing lines, which significantly improves work efficiency and reduces labor intensity.

[0010] 2. Using magnetic adsorption or raised step snap-fit ​​methods, the device can be quickly fixed to the metal surface or holes of the vehicle body, achieving non-destructive installation. Attached Figure Description

[0016] like Figure 1 As shown, a non-accessible car hood opening mechanism includes a fixed base 1, a cam plate 2, and a push rod 3.

[0017] like Figure 2 As shown, the fixed base 1 has a receiving cavity 10 for accommodating the cam disk 2.

[0018] The cam disk 2 is rotatably connected within the receiving cavity 10. The receiving cavity 10 provides installation and movement space for the cam disk 2, integrating the cam disk 2 into the fixed base 1.

[0019] The cam disk 2 has a working part; the working part may have a circular arc profile, or be elliptical or polygonal. The outer contour of the working part matches the shape of the receiving cavity 10.

[0020] like Figure 3 and Figure 4 As shown, a limiting post 11 is fixedly connected inside the receiving cavity 10, and a sliding groove 21 is provided on the cam disk 2. The limiting post 11 is inserted into the sliding groove 21 and can slide within the sliding groove 21. The limiting post 11 can control the movement trajectory of the cam disk.

[0021] The fixed base 1 is also provided with a push rod cavity that communicates with the receiving cavity 10. The side of the push rod cavity is provided with an opening 12. The push rod 3 passes through the opening 12 into the push rod cavity and can slide along the opening axis.

[0022] One end of the push rod 3 is connected to the lever 7 of the hood lock, and the other end extends into the receiving cavity 10; the push rod 3 can be driven by the cam plate 2 in the receiving cavity 10 and the push rod cavity, and can also pass out from the side to connect to the external lock.

[0023] The push rod 3 inside the receiving cavity 10 is located on the movement trajectory of the working part of the cam disk 2; when the cam disk 2 rotates, the working part will come into contact with the push rod 3 during the rotation process.

[0024] The lever 7 is hinged to the fixed base 1, and the cam disk 2 is connected to an operating unit for driving the cam disk 2 to rotate. When the cam disk 2 is driven to rotate by the operating unit, the working part of the cam disk 2 can push the push rod 3 to move axially, thereby driving the lever 7 to move and open the hood lock.

[0025] The control unit is a movable handle 5 fixed to the cam disk 2, and a pull cable is connected to the movable handle 5. The movable handle 5 is provided with a pull cable hole, and the pull cable is connected to the pull cable. The operator can pull the pull cable from outside the vehicle cabin (such as near the door handle, in a concealed place on the front bumper, etc.) to remotely drive the movable handle 5 to swing, thereby driving the cam disk 2 to rotate.

[0026] This opening mechanism is a temporary installation and needs to be removed after production, testing, and maintenance. Installing it with screws is complex and can damage the vehicle body. To solve these problems, such as... Figure 5 As shown, the bottom of the fixing base 1 is provided with a magnet 8 for attracting and fixing the opening mechanism to the metal surface of the vehicle body. Compared with methods such as drilling, bonding or mechanical clamping, magnetic fixing is damage-free and will not leave damage to the paint or body of the vehicle.

[0027] The bottom of the mounting base 1 is provided with a raised step for engaging with holes in the vehicle body. Existing hole structures such as process holes, assembly holes, or drainage holes are commonly found in areas such as the car hood, front bulkhead, or fenders. The raised step can be directly engaged into these holes, utilizing the existing structure of the vehicle body as an installation reference.

[0028] For example, such as Figure 6 As shown, this opening mechanism 90 can be installed in the mounting hole of the car's front hood lock 91.

[0029] In another embodiment, a cover plate 4 is also included, which is placed on the fixing base 1 and closes the receiving cavity 10. The cover plate 4 prevents external dust and other contaminants from entering the receiving cavity 10.

[0030] When in use, the opening mechanism is fixed to the front edge of the hood, near the lock body, or other easily accessible metal surfaces or holes on the vehicle body by means of magnetic attraction or by means of protruding steps.

[0031] During installation, locate the original hood lock assembly 91, remove the lock assembly housing or cover to expose the unlock lever 7 inside, and use an extension rod (or flexible cable) to fix one end of it to the original unlock lever 7 by means of clamps, fixing pins or drilling. Guide the other end of the extension rod to the predetermined installation position of this mechanism outside the vehicle, fix this opening mechanism 90, and finally hinge one end of the push rod 3 to the exposed end of the extension rod.

[0032] In another embodiment, the hood lock assembly 91 has a dedicated external operating interface (such as an exposed lever arm or connector). During installation, the opening mechanism 90 is fixed to a predetermined mounting position on the vehicle body (such as behind the bumper grille) by the magnet 8 or the raised step, and then one end of the push rod 3 is directly hinged to the external operating interface via a ball joint, pin, or quick-connect fitting.

[0033] The operator pulls the cable connected to the movable handle 5, causing the handle 5 to swing, which in turn drives the cam disk 2 to rotate. During rotation, the working part on the cam disk 2 pushes the push rod 3 to extend axially. The extended end of the push rod 3 actuates the hood lock lever 7 connected to the push rod 3, simulating the unlocking process of pulling the lever with a cable inside the car, thereby releasing the hood lock.

[0034] To ensure reliable reset after the mechanism has been in operation, a reset spring is added. The reset spring is a torsion spring, sleeved on the rotating shaft of the cam disk. One arm of the torsion spring rests against the inner wall of the fixed base 1, and the other arm rests against the non-working part of the cam disk 2 or the moving handle 5. When the cam disk 2 is driven to rotate by the operating unit, the torsion spring is tightened and stores energy; when the operating force disappears, the torsion spring releases energy, driving the cam disk 2 to automatically rotate back to its initial position and causing the push rod 3 to retract. The limiting post 11 slides back to its initial position along the sliding groove 21. The limiting post 11 forms a stop when it contacts both ends of the sliding groove 21.

[0035] It should be noted that the hood lock assembly and cam disc in this embodiment are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0036] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
