Description

Technical Field

[0001] This utility model relates to the field of mechanical and electronic technology, and more particularly to a locking device and an electric vehicle. Background Technology

[0002] In electric vehicles, locking devices are typically used to lock the charging gun while it is charging the vehicle. However, when the vehicle is without power, the locking device cannot be unlocked by electric drive. In this case, the only way to unlock it in an emergency is to pull a cord located at the rear of the locking device. Because the cord is located at the rear of the locking device, it has the following disadvantages:

[0003] Reduced reliability: As an additional mechanical connection device, the pull rope increases the complexity of the system and the potential for failure. The pull rope may wear out, stretch, or break due to long-term use, causing the locking device to malfunction and affecting the safety of the vehicle.

[0004] Inconvenient operation: The driver needs to find the location of the pull rope inside the vehicle and pull it forcefully to unlock the vehicle. This may cause delays in some emergency situations and affect the driver's timely control of the vehicle. In particular, some poorly designed pull rope layouts may cause inconvenience to the driver and may even lead to misoperation during operation.

[0005] Space occupation: The pull cord requires a certain amount of space to be arranged, which will affect the interior layout and aesthetics of the vehicle. In the case of relatively limited interior space in electric vehicles, the presence of the pull cord may make the interior of the vehicle appear more crowded, and may interfere with other components, increasing the difficulty of vehicle design and manufacturing.

[0006] Safety hazard: If the pull cord is exposed in a location easily accessible to passengers inside the vehicle, it may be accidentally pulled or played with by passengers, causing the locking device to unlock unexpectedly and thus leading to a safety accident.

[0007] Therefore, there is a need to provide a locking device that is highly reliable, easy to operate, compact in size, and safe to use. Utility Model Content

[0008] The embodiments of this utility model are intended to solve at least one aspect of the above-mentioned problems.

[0009] According to one aspect of the present invention, a locking device is provided, comprising: a housing; a carrier member disposed within the housing; a driving member disposed within the housing and configured to drive the carrier member to move between a locked position and an unlocked position; a first rod disposed on the carrier member and configured to extend from one side of the housing when the carrier member is in the locked position to perform a locking function, and to retract at least partially into the housing when the carrier member is in the unlocked position to perform an unlocking function; and a second rod disposed on the carrier member and configured to extend from said side of the housing when the carrier member is in the locked position, so as to be pushed to at least partially actuate the first rod. The second lever retracts into the housing to unlock the vehicle, allowing users to rescue those trapped inside when the vehicle is without power. The locking device is simple in structure and easy to operate. Unlike pull ropes, the second lever can be made of any durable and wear-resistant material, preventing wear, stretching, or breakage over time. Therefore, it is more reliable than traditional pull ropes. Since the second lever is located on the same side of the housing (front) and is shorter than a traditional pull rope, it doesn't occupy much space, minimizing its impact on the vehicle's interior layout and aesthetics. Furthermore, its front location prevents accidental pulling or playing with by passengers, avoiding accidental unlocking and potential safety hazards.

[0010] According to one aspect of the present invention, the housing includes: a body for accommodating a portion of a carrier member provided with a first rod and a drive member; and a cover covering the body and provided with a boss for accommodating a portion of the carrier member provided with a second rod, the boss extending only on a portion of the body to accommodate only the portion provided with the second rod, thereby making the housing more compact.

[0034] See Figures 1 to 6 This utility model discloses a locking device 1000 and an electric vehicle (not shown in the figure) including the locking device 1000.

[0035] The locking device 1000 includes a housing 100, a carrier 200, a drive member, a first lever 400, and a second lever 500. The housing 100 extends along a first direction D1 (also referred to as the "longitudinal direction"). The carrier 200 has a height along a second direction D2 (also referred to as the "height direction") orthogonal to the first direction D1. The carrier 200 is disposed within the housing 100. The drive member is disposed within the housing 100 and is used to drive the carrier 200 to move between a locked position and an unlocked position. The first lever 400 is disposed on the carrier 200 and configured to extend from one side (also referred to herein as the "front side") of the housing 100 when the carrier 200 is in the locked position to achieve a locking function, and to retract at least partially into the housing 100 when the carrier 200 is in the unlocked position to achieve an unlocking function. The second lever 500 is mounted on the carrier 200 and configured to extend from this side of the housing 100 when the carrier 200 is in the locked position. This allows it to be pushed in an emergency where the locking device 1000 cannot be electrically driven due to a collision, fire, or other reasons, so as to cause the first lever 400 to retract at least partially into the housing 100 to achieve the unlocking function. That is, it allows the user to unlock the locking device 1000 to rescue people trapped inside the electric vehicle when the vehicle is not electrically driven.

[0036] The locking device 1000 has a simple structure and is easy to operate. The second lever 500 can be made of any wear-resistant and durable material (such as metal), and unlike a pull rope, it will not wear, stretch, or break due to long-term use, thus offering higher reliability than traditional pull ropes. Since the second lever 500 and the first lever 400 are located on the same side of the housing 100, i.e., the front side, and are shorter than traditional pull ropes, the second lever 500 does not occupy much space, having minimal impact on the interior layout and aesthetics of the vehicle. Furthermore, because the second lever 500 is located on the front side of the housing 100, it will not be accidentally pulled or played with by passengers, preventing accidental unlocking of the locking device 1000 and potential safety accidents.

[0037] The locking device 1000 also includes a seal 600. The seal 600 is disposed between at least one of the first rod 400 and the second rod 500 and the housing 100 to prevent contaminants such as water and debris from entering the housing 100 and causing malfunctions such as short circuits or wear of mechanical parts in the locking device 1000, thereby improving the reliability and durability of the locking device 1000 and facilitating its use in harsh environmental conditions such as rain and snow.

[0038] See Figures 1 to 3 The housing 100 includes a body 110 and a cover 120. The body 110 is used to receive the portion of the carrier 200 provided with the first rod 400 and the drive member. The cover 120 covers the body 110 and is provided with a boss 121 for receiving the portion of the carrier 200 provided with the second rod 500 (i.e., the second end 212 described below). The boss 121 extends only along a first direction D1 over a portion of the body 110 to accommodate only the portion provided with the second rod 500, making the housing 100 more compact.

[0039] See Figures 3 to 6 The support member 200 includes a first support portion 210 extending along a second direction D2 and a second support portion 220 extending along a first direction D1. The first support portion 210 includes a first end 211 (also referred to as the "bottom end") on which the first rod 400 is disposed and a second end 212 (also referred to as the "top end") on which the second rod 500 is disposed. The second support portion 220 is housed in the body 110 for operably connecting to the drive member for being driven by the drive member. The second end 212 is higher than the body 110 to facilitate the placement of the second rod 500 on the second end 212, and the specific value by which the second end 212 is higher than the body 110 can be adjusted according to specific needs. The boss 121 is configured to accommodate only the second end 212, avoiding making the housing 100 too large and thus avoiding excessive occupation of the interior space of the electric vehicle.

[0040] See Figures 4 to 6 The second support portion 220 is provided with a plurality of teeth 221 arranged along the first direction D1. The driving member includes a gear set 310 that meshes with the teeth 221 and a motor 320 that drives the gear set 310. The motor 320 is electrically driven, and for clarity, the circuit of the motor 320 is not shown in the figure.

[0041] Furthermore, the motor 320 includes an output shaft 321. The gear set 310 includes a first gear 311, a second gear 312, and a third gear 313. The first gear 311 is mounted on the output shaft 321, and when the motor 320 is operating, the output shaft 321 rotates to drive the first gear 311 to rotate. The second gear 312 meshes with the first gear 311 to be driven to rotate by the first gear 311. The third gear 313 is connected to the second gear 312 via a connecting shaft 314 to be driven to rotate by the second gear 312, and the third gear 313 meshes with the gear 221 to drive the second support portion 220 and the first support portion 210 to move back and forth along the first direction D1. When the motor 320 is energized, it transmits power to the support member 200 through the gear set 310 in this manner, causing the first lever 400 to move between a locked position and an unlocked position.

[0042] See also Figures 4 to 6 The first support portion 210 has a protruding stop portion 213 on its side opposite to the first rod 400 and the second rod 500. The stop portion 213 extends along the second direction D2 beyond the second end 212 of the second rod 500 to avoid being accommodated by the boss 121, so that the boss 121 can be used only to accommodate the second end 212 and has a small volume. The stop portion 213 is configured to abut against the connecting shaft 314 when the support member 200 moves to the unlocked position to prevent the support member 200 from continuing to move backward along the first direction D1.

[0043] See also Figure 5 The first gear 311 and the stop portion 213 are respectively located on both sides of the connecting shaft 314. The second gear 312 and the third gear 313 are respectively located on both sides of the stop portion 213 and face each other. However, those skilled in the art should understand that this is only one specific embodiment of the gear set 310 of this utility model, and the number of gears in the gear set 310 and their relative positions are not limited thereto. As long as the gear set 310 can transmit the power of the motor 320 to the carrier 200, the gear set 310 can adopt any suitable arrangement.

[0044] See also Figure 6The stop portion 213 is constructed in an "L" shape, and the "L" shape has a curved surface 2131 at its bend that matches the shape of the connecting shaft 314, so as to minimize the collision between the connecting shaft 314 and the stop portion 213 and reduce the damage to the connecting shaft 314 and the stop portion 213 caused by excessively strong collisions, thereby improving the durability of the locking device 1000. The first bearing portion 210 has a base plate 214 at its first end 211 on the side of the stop portion 213 opposite to the gear 221, so that the second gear 312 is located above the base plate 214 to provide protection for the second gear 312 and prevent other devices or the user's fingers from touching or colliding with the second gear 312 during assembly.
