Description

Technical Field

[0001] This utility model relates to a vehicle, and more particularly to a vehicle. Background Technology

[0002] Currently, electrically operated hood release locks significantly improve the convenience of unlocking the hood for users and are increasingly widely used in new energy vehicles and high-end passenger cars. However, because their core unlocking function relies on a motor structure, they cannot be activated in special emergency scenarios such as power outages. Therefore, a backup mechanical unlocking structure is still needed for emergency use. However, such backup mechanical unlocking devices require unlocking from outside the vehicle, which can easily become a security vulnerability for unauthorized opening of the hood. Therefore, there is an urgent need to develop vehicles that combine emergency unlocking and anti-theft functions. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a vehicle with a high level of security, capable of unlocking the hood from the outside.

[0004] According to a first aspect of the present invention, the vehicle includes a front hood, a floor guard plate, and a hood lock, wherein a front engine compartment is provided between the front hood and the floor guard plate, and the hood lock is used to lock or unlock the front hood.

[0005] The vehicle also includes a first cable, which is disposed in the front engine compartment. A first end of the first cable is connected to the hood lock, and a second end of the first cable has an operating part. The first cable is configured to unlock the hood lock by pulling the operating part.

[0006] The bottom protective plate has an operating hole configured to allow a tool to be inserted upward into the forward engine compartment to connect to and pull the operating unit.

[0007] The vehicle according to the embodiments of this utility model has at least the following beneficial effects:

[0008] By installing a first pull cable inside the front engine compartment, the cable includes an operating part that allows the hood lock to be unlocked by pulling the operating part. An operating hole is located on the underbody protection plate. A tool is inserted upwards through the operating hole and into the front engine compartment to pull the operating part, thereby unlocking the hood lock and allowing the hood to be opened from the outside in an emergency. Because the operating hole is located on the underbody protection plate, operation requires inserting a tool under the chassis, aligning and passing it through the operating hole, and connecting and pulling the operating part. This operation is relatively difficult when the vehicle is on the ground, requiring the vehicle to be lifted for the unlocking operation. Therefore, this design ensures safety and protects items in the front engine compartment storage compartment. Furthermore, this backup unlocking structure only requires adding a first pull cable and an operating hole to the existing structure, making it cost-effective.

[0009] According to some embodiments of the present invention, the distance between the operating hole and the operating part along the height direction of the vehicle is between 200mm and 400mm.

[0010] According to some embodiments of the present invention, along the height direction of the vehicle, the distance between the operating hole and the lowest point of the vehicle tire in the ground state is less than the distance between the operating hole and the operating part.

[0011] According to some embodiments of this utility model, the diameter of the operating hole is between 10mm and 20mm.

[0012] According to some embodiments of the present invention, the projection of the operating part on the horizontal plane is located within the circular area with a radius of 45mm centered on the center of the operating hole.

[0013] According to some embodiments of the present invention, the projection of the operating part on the horizontal plane at least partially coincides with the projection of the operating hole on the horizontal plane.

[0014] According to some embodiments of this utility model, the cover lock and the first pull cord are each provided with one or two, wherein the number of operating holes is equal to the number of the first pull cords.

[0015] According to some embodiments of the present invention, the vehicle includes a front frame, and the hood lock is mounted on the front frame;

[0016] The vehicle also includes a connector, one end of which is connected to the front frame, and the other end of which constrains the second end of the first pull wire in the horizontal plane.

[0017] According to some embodiments of the present invention, the connector includes a snap-fit ​​part, and the front end frame has a slot, wherein the snap-fit ​​part engages with the slot.

[0018] According to some embodiments of the present invention, the first pull wire includes a pull wire sheath and a pull wire core, the pull wire core is disposed inside the pull wire sheath and is movable relative to the pull wire sheath, wherein the operating part is a pull ring structure formed at the end of the pull wire core.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0043] In related technologies, a unlocking structure for a vehicle in a power-off state is provided, including a hood unlocking cable. One end of the hood unlocking cable is fixed to the front bumper beam. The front bumper has an opening corresponding to the end of the hood unlocking cable fixed to the front bumper beam, and a decorative cover is added to the opening. Although the opening of this unlocking structure is located on the front bumper beam and a decorative cover is provided for concealment and decoration, its security is still relatively low. Furthermore, the hood unlocking cable needs to extend to the front bumper beam, thus requiring a longer cable length, further increasing the cost of use.

[0044] Please refer to the following for details. Figures 1-7 This application provides a vehicle, which includes a front hood 600, a bottom guard plate 100, and a hood lock 200. For ease of understanding, the directions in this utility model are first defined as follows: The directions of up, down, front, back, left, and right involved in this utility model refer to the vehicle's orientation in the O-XYZ coordinate system. The origin O coincides with the vehicle's center of mass. The front end refers to the X direction parallel to the ground pointing forward, the rear end refers to the X direction parallel to the ground pointing backward, the left side refers to the Y direction parallel to the ground pointing to the driver's left, the right side refers to the Y direction parallel to the ground pointing to the driver's right, the upper end refers to the Z direction passing through point O pointing upward, and the lower end refers to the Z direction passing through point O pointing downward. The XY plane is a horizontal plane.

[0045] Please refer to Figure 1 A front engine compartment is located between the hood 600 and the underbody protection plate 100. The hood 600 is situated above the front engine compartment and is used to close or open it. Some electric vehicles have storage compartments within the front engine compartment, and the hood 600 also serves to close or open these storage compartments. The underbody protection plate 100 is located below the front bumper and is used to block upward impacts from stones kicked up from the road surface during vehicle operation.

[0046] The hood lock 200 is located at the edge of the front engine compartment and is used to lock or unlock the front hood 600. The vehicle also includes a second cable, one end of which is connected to the hood lock 200 and the other end is connected to the drive motor, so that the hood lock 200 can be automatically unlocked under the drive of the drive motor.

[0047] Please refer to Figures 2-4 The vehicle also includes a first cable 400, which is located in the front engine compartment. The first end of the first cable 400 is connected to the hood lock 200, and the second end of the first cable 400 has an operating part 410. The first cable 400 is configured to unlock the front hood 600 by pulling the operating part 410.

[0048] Please refer to Figure 4 and Figure 6 The underbody protection plate 100 has an operating hole 100a, which is configured to allow a tool to be inserted upward into the front engine compartment to connect to and pull the operating unit 410. It is understood that in normal use, the underbody protection plate 100 is located at the bottom of the vehicle, therefore the operating hole 100a on the underbody protection plate 100 is not visually apparent, and thus the provision of the operating hole 100a does not affect the appearance of the vehicle.

[0049] The first end of the first pull cable 400 can be directly connected to the hood lock 200 or indirectly connected. For example, the first end of the pull cable can be connected to the second pull cable, and indirectly connected to the hood lock 200 through the second pull cable. In this way, by pulling the operating part 410, the force can be transmitted to the hood lock 200 through the second pull cable, thereby unlocking the hood 600.

[0050] In some embodiments, for the direct connection between the first pull cable 400 and the cover lock 200, the cover lock 200 has a pull cable interface, and the first end of the first pull cable 400 has a ball joint or a snap-fit ​​joint. The joint is snapped into the pull cable interface to ensure that there is no looseness, thus realizing the connection between the first pull cable 400 and the cover lock 200.

[0051] For the structure of the first pull wire 400, please refer to... Figure 7 In some embodiments, the first pull wire 400 includes a pull wire sheath 420 and a pull wire core 430. The pull wire sheath 420 is made of PVC or nylon material, and the pull wire core 430 is typically made of multi-strand wound steel wire rope, which is formed into a flexible wire body through a twisting process. The pull wire core 430 is disposed inside the pull wire sheath 420 and is movable relative to the pull wire sheath 420.

[0052] For the specific structure of the operating unit 410, please refer to [reference needed]. Figure 7In some embodiments, the operating part 410 is a pull ring structure formed at the end of the pull wire core 430. Correspondingly, the tool has a hook that can extend into the pull ring structure to establish a connection with it.

[0053] In the above embodiment, a first pull cable 400 is installed inside the front engine compartment. The first pull cable 400 has an operating part 410, which can be pulled to unlock the hood lock 200 and the front hood 600. The underbody protection plate 100 has an operating hole 100a. A tool is inserted upwards through the operating hole 100a and into the front engine compartment to pull the operating part 410, thereby unlocking the hood lock 200 and allowing the hood 600 to be opened from outside the vehicle in an emergency. Furthermore, since the operating hole 100a is located on the underbody protection plate 100, operation requires inserting a tool under the chassis, aligning it with and passing it through the operating hole 100a, and connecting and pulling the operating part 410. This operation is relatively difficult when the vehicle is on the ground, requiring the vehicle to be lifted for the unlocking operation. Therefore, this method offers concealment and security, ensuring the safety of items in the storage compartment of the front engine compartment. Furthermore, when the vehicle's battery is low, the front hood 600 can be opened from the outside of the vehicle to recharge it. In addition, this backup unlocking structure only requires the addition of a first pull cable 400 to the existing structure and the setting of an operation hole 100a on the underbody protection plate 100, which is low cost.

[0054] In some embodiments, the distance between the operating hole 100a and the operating part 410 along the height direction of the vehicle, i.e., the aforementioned vertical direction, is between 200mm and 400mm. In some specific embodiments, the first pull cable 400 extends toward the bottom guard plate 100, and the distance between the operating hole 100a and the operating part 410 is 200mm, 250mm, 300mm, 357mm, or 400mm.

[0055] Understandably, since there is a significant distance between the operating part 410 of the first cable 400 and the underbody protection plate 100, the length of the first cable 400 can be reduced, thereby reducing the cost of setting the first cable 400 and thus reducing the overall vehicle manufacturing cost. Furthermore, it can reduce the risk that the operating part 410 can be connected to and the hood 600 unlocked by others using other tools when the vehicle is on the ground, further improving safety.

[0056] In some embodiments, along the height direction of the vehicle, the distance between the operating hole 100a and the lowest point of the vehicle tire in the ground-penetrating state is less than the distance between the operating hole 100a and the operating part 410. It can be understood that when the vehicle is on the ground, the distance between the lower edge of the operating hole 100a and the lowest point of the vehicle tire in the ground-penetrating state is the same as the distance between the underbody protection plate 100 and the ground, which is also the maximum size of a tool that can be aligned with the operating hole 100a in an upright position. By limiting the distance between the lower edge of the operating hole 100a and the operating part 410, it is difficult for tools to enter the operating hole 100a under normal use scenarios, thereby improving the anti-theft effect.

[0057] In some embodiments, the diameter of the operating hole 100a is between 10mm and 20mm. In some specific embodiments, the diameter of the operating hole 100a is 10mm, 15mm, 17.2mm, or 20mm.

[0058] Understandably, the underbody protection plate 100 is used to block the upward impact of stones splashed from the road surface during vehicle operation. By limiting the diameter of the operating hole 100a to between 10mm and 20mm, which is relatively small, stones are less likely to pass through the operating hole 100a and enter the front engine compartment. It also increases the difficulty of connecting the operating unit 410 when the vehicle is on the ground, thereby improving the anti-theft effect and ensuring security.

[0059] It is understood that the operating part 410 is located above the operating hole 100a to facilitate the connection between the tool extending upward from the operating hole 100a and the operating part 410. In some embodiments, a circular area with a radius of 45mm is drawn in the horizontal plane with the center of the operating hole 100a as the center, and the projection of the operating part 410 on the horizontal plane lies within the circular area. In this way, the tool extending upward from the operating hole 100a into the forward engine compartment can establish a connection with the operating part 410 to achieve unlocking without large-angle deflection.

[0060] Furthermore, in some embodiments, the projection of the operation part 410 on the horizontal plane at least partially overlaps with the projection of the operation hole 100a on the horizontal plane, thereby further reducing the difficulty of the above-mentioned unlocking operation.

[0061] In some embodiments, one or two hood locks 200 and first pull cables 400 are provided. The vehicle includes a front-end frame 300, which serves as the mounting carrier for multiple components such as headlights, hood locks 200, and horns. When one hood lock and one first pull cable 400 are provided, they are distributed on one side of the front-end frame 300 along the vehicle width direction, which is the aforementioned left-right direction. Please refer to... Figure 4When both the hood 600 and the first pull cable 400 are provided in twos, the hood lock 200 and the first pull cable 400 are respectively arranged on opposite sides of the front frame 300 along the vehicle width direction.

[0062] The number of operating holes 100a is equal to the number of first pull wires 400. That is, each operating part 410 has a corresponding operating hole 100a, which facilitates the insertion of the corresponding operating hole 100a to perform the unlocking operation of each operating part 410.

[0063] In some embodiments, please refer to Figure 3 and Figure 5 The vehicle also includes a connector 500, one end of which is connected to the front frame 300, and the other end of which constrains the second end of the first cable 400 in the horizontal plane. The connector 500 constrains the position of the second end of the first cable 400 in the horizontal plane so that the second end of the first cable 400 remains relatively fixed in the horizontal direction with the front frame 300 during vehicle operation.

[0064] The second end of the first pull wire 400 is the portion of the pull wire core 430 extending out of the pull wire sheath 420 in a direction away from the first end. The connector 500 includes a sleeve structure 520 and a snap-fit ​​portion 510 connected to the sleeve structure 520. The portion of the pull wire core 430 extending out of the pull wire sheath 420 passes through the sleeve structure 520 of the connector 500, thereby constraining the position of the second end of the first pull wire 400 in the horizontal plane. The pull wire core 430 is slidable relative to the sleeve structure 520.

[0065] In some embodiments, reference is made to Figure 5 The front frame 300 has a slot 300a, and the snap-fit ​​portion 510 of the connector 500 engages with the slot 300a. This allows the connector 500 to snap onto the front frame 300, thereby horizontally constraining the pull wire core 430 at the second end of the first pull wire 400. This snap-fit ​​engagement improves the efficiency of the first pull wire 400's arrangement.

[0066] In some specific embodiments, the engaging structure of the latching part 510 and the slot 300a includes a latching body 511 and a pair of latching teeth 512 arranged laterally on the latching body 511. The latching teeth 512 are arranged on opposite sides of the latching body 511 and protrude outwards. The latching teeth 512 are used to engage with the slot 300a of the front end frame 300. Along the latching direction, multiple sets of latching teeth 512 are arranged at intervals on both sides. The latching teeth 512 are elastically deformable, so that under the action of external force, they can deform and shrink through the slot 300a, and then return to the position of engaging in the slot 300a. The latching teeth 512 are inclined towards the pull wire core 430. The inclined latching teeth 512 can guide the latching part 510 through the slot 300a and can improve the stability of the engagement.

[0067] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
