Description
Technical Field
[0001] This utility model relates to the field of vehicle parts technology, and in particular to a locking device for automobiles. Background Technology
[0002] Today, cars, as an indispensable means of transportation in modern life, have permeated people's daily travel, greatly improving the convenience and efficiency of travel. However, while enjoying the convenience brought by cars, there are also some design shortcomings that may significantly affect the user experience and even pose safety hazards in certain situations.
[0003] Of particular concern is the potential risk of hands being pinched in the door design of some vehicle types, such as vans and MPVs (multi-purpose vehicles) with sliding rear doors. In these models, both the front and rear doors face the same area when closed, namely the B-pillar region. The B-pillar is a crucial structural support and a frequently used handrail area for getting in and out of the vehicle; its unique position causes an overlap between the door's closing mechanism and the user's range of motion.
[0004] Specifically, when the front door is about to close while a user is getting on or off at the rear door, or vice versa, when the rear door is closing while a user is moving around at the front door, the rapid and forceful closing of the doors can easily cause an accident where a hand is caught in the door. This design flaw not only affects the user's normal experience but also threatens their personal safety to some extent. Utility Model Content
[0005] The purpose of this utility model is to solve the technical problem in the prior art where, when the front door of a car is about to close while a user is getting on or off at the rear door, or vice versa, when the rear door is closing while a user is moving around at the front door, the rapid and forceful closing action of the car door can easily cause a hand to be pinched inadvertently.
[0006] To solve the above-mentioned technical problems, the present invention discloses a locking device for automobiles. This locking device is installed on the B-pillar of the automobile and is used to cooperate with the front door lock and the rear door lock of the automobile.
[0007] The locking device includes a first latch and a second latch arranged at intervals, and a connector connecting the first latch and the second latch. The connector is movably mounted on the B-pillar of the car.
[0008] Furthermore, the first latch has a first locking portion adapted to be fitted with the front door lock, and the second latch has a second locking portion adapted to be fitted with the rear door lock.
[0009] The connector can move the first latch and the second latch in a first position and a second position; wherein, the first locking part in the first position corresponds to the front door lock and the second locking part in the first position corresponds to the rear door lock; the first locking part in the second position is offset from the front door lock and the second locking part in the second position is offset from the rear door lock.
[0010] Using the above technical solution, this locking device is mounted on the B-pillar of the car, and the first and second latches respectively meet the locking requirements of the front and rear door locks. Furthermore, this locking device can be adjusted via a connecting component to switch between a first position and a second position. When both the front and rear doors are closed, the first latch in the first position locks the front door; the second latch in the first position locks the rear door. When both the front and rear doors are open, both the first and second latches are in the second position. If one of the front or rear doors is closed, it will not be immediately locked because the locking mechanism is offset from the door lock, preventing passengers on the other side from having their hands trapped in the door. Locking of both doors is achieved only when the first and second latches are moved together to the first position by the connecting component.
[0011] This locking device connects the first and second latches via a connector, ensuring that each door has an anti-pinch process before closing, thus improving safety during the door locking process.
[0012] The present invention also discloses a locking device for automobiles, wherein the connecting member is configured as a connecting rod extending along the length of the vehicle body, and the connecting rod is rotatable relative to the B-pillar of the automobile about its axis.
[0013] Furthermore, the first locking part is configured as a first locking hole that passes through the first latch along a direction perpendicular to the axis of the connecting rod.
[0014] The second locking part is configured as a second locking hole that passes through the second latch along a direction perpendicular to the axis of the connecting rod.
[0015] The first locking hole and the second locking hole, located in the first position, both extend in a direction parallel to the horizontal.
[0016] Using the above technical solution, the first and second latches rotate along the connecting rod extending along the length of the vehicle body without displacement, thereby changing the orientation angle of the locking hole on the latch. This allows the locking hole to switch between a position aligned with the door lock and a position offset from the door lock. This structure, while satisfying the anti-pinch function during door closing, reduces the space occupied by the latches during position switching, making it more suitable for placement on the B-pillar.
[0017] The present invention also discloses a locking device for automobiles, wherein the first locking device is configured as a spherical structure, and two first locking holes are symmetrically arranged on the first locking device relative to the axial extension direction of the connecting rod.
[0018] The second latch is configured as a spherical structure, and two second locking holes are provided on the second latch symmetrically with respect to the axial extension direction of the connecting rod.
[0019] Using the above technical solution, the outer wall of the spherical lock is smooth and has no sharp edges, so even if a passenger's limbs accidentally collide with the lock, it is not easy to scratch the body. Furthermore, this spherical structure is more aesthetically pleasing.
[0020] Furthermore, each latch is symmetrically equipped with two locking holes, so that by rotating the connecting rod 90 degrees, the locking holes on the latch can be switched between being aligned with the door lock and being offset from the door lock.
[0021] The present invention also discloses a locking device for automobiles. The locking device further includes a driving component and a transmission component. The driving component is disposed on the B-pillar of the automobile. The transmission component is connected to the driving component and sleeved on the connecting rod. The driving component drives the transmission component to rotate the connecting rod around its axis.
[0022] The present invention also discloses a locking device for automobiles, the locking device further including a mounting bracket, which is fixed to the B-pillar and is used to rotatably mount the connecting rod to the B-pillar.
[0023] A support bearing is provided between the connecting rod and the mounting bracket. The support bearing includes an outer ring, an inner ring, and multiple rolling elements disposed between the outer ring and the inner ring. The outer ring of the support bearing is fixedly connected to the mounting bracket, and the inner ring of the support bearing is fixedly connected to the connecting rod.
[0024] The present invention also discloses an automobile, including a body, a front door and a rear door connected to the body, and any of the above-mentioned locking devices for automobiles.
[0025] By adopting the above technical solution, this car integrates the front door latches and rear door latches together through the aforementioned latching device. The front door latches and rear door latches can switch positions in a consistent manner. This ensures that when one of the front or rear doors is in the open state, during the closing process, because the position of the latch is misaligned with the corresponding door lock, there is an anti-pinch process before locking. The door can only be locked when the position of the latch is aligned with the corresponding door lock, thus improving the safety of the car.
[0026] Specifically, the front doors of this car are designed as swing doors, and the rear doors are designed as sliding doors.
[0027] The beneficial effects of this utility model are as follows:
[0028] This utility model discloses a locking device for automobiles. The locking device includes a first latch, a second latch, and a connecting member connecting the first and second latches. The connecting member can adjust the positions of the first and second latches, allowing them to switch between a first position and a second position. When both the front and rear doors are closed, the first latch in the first position locks the front doors; the second latch in the first position locks the rear doors. When both the front and rear doors are open, both the first and second latches are in the second position. If one of the front or rear doors is closed, it will not be immediately locked because the locking part is offset from the door lock, thus creating an anti-pinch process to prevent passengers getting their hands caught in the door. Locking of both doors is achieved only when the first and second latches are moved together to the first position by the connecting member. Attached Figure Description

[0043] In some vehicle types, such as vans and MPVs (multi-purpose vehicles) with sliding rear doors, there is a potential risk of hand pinching. In these vehicles, both the front and rear doors face the same area when closed, namely the B-pillar region. The B-pillar is a crucial structural support and a frequently used handrail area for passengers getting in and out. If the front door is about to close while a passenger is still getting in or out of the rear door, the closing front door may lock due to inertia, trapping the rear passenger's hand between the door and the B-pillar, potentially causing hand injury or even finger fractures, threatening their safety. The same situation exists when the rear door is about to close while a passenger is still getting in or out of the front door.
[0044] Therefore, this utility model provides a locking device for automobiles. This locking device includes a first latch, a second latch, and a connecting member connecting the first and second latches. The connecting member can adjust the positions of the first and second latches, allowing them to switch between a first position and a second position. When both the front and rear doors are closed, the first latch in the first position locks the front doors; the second latch in the first position locks the rear doors. When both the front and rear doors are open, both the first and second latches are in the second position. If either the front or rear door is closed, it will not be immediately locked because the locking part is offset from the door lock, thus preventing hand pinching.
[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0046] like Figure 1 and Figure 5 As shown, an embodiment of the present invention provides a locking device 10, which is disposed on the B-pillar 20 of a car and is used to cooperate with the front door lock and the rear door lock of the car.
[0047] The locking device 10 includes a first latch 100 and a second latch 200 spaced apart, and a connector 300 connected between the first latch 100 and the second latch 200. The connector 300 is movably mounted on the B-pillar 20 of the car.
[0048] Furthermore, the first latch 100 has a first locking portion 110 adapted to the front door lock, and the second latch 200 has a second locking portion 210 adapted to the rear door lock.
[0049] The connector 300 can move the first latch 100 and the second latch 200 in a first position and a second position in a linkage manner; wherein, the first locking part 110 in the first position corresponds to the front door lock and the second locking part 210 in the first position corresponds to the rear door lock; the first locking part 110 in the second position is offset from the front door lock and the second locking part 210 in the second position is offset from the rear door lock.
[0050] This locking device 10 is mounted on the B-pillar 20 of the vehicle, and the first latch 100 and the second latch 200 respectively meet the locking requirements of the front door lock and the rear door lock. Furthermore, this locking device 10 can adjust the positions of the first latch 100 and the second latch 200 through the connector 300, so that it can switch between a first position and a second position. When both the front and rear doors are closed, the first latch 100 in the first position can lock the front door lock; the second latch 200 in the first position can lock the rear door lock. When both the front and rear doors are open, the first latch 100 and the second latch 200 are both in the second position. If one of the front or rear doors is closed, it will not be locked immediately because the locking part is offset from the door lock, thus preventing passengers getting in and out of the other door from having their hands caught in the door. Only when the first latch 100 and the second latch 200 are moved together to the first position by the connecting piece 300 can both doors be locked.
[0051] This locking device 10 connects the first latch 100 and the second latch 200 through the connector 300, so that there is an anti-pinch process before any car door is closed, which improves the safety of the car door locking process.
[0052] The structure of the first latch 100, the second latch 200, and the connector 300 will be described in detail below.
[0053] Alternatively, in one embodiment, such as Figure 2 and Figure 4 As shown, the connector 300 is configured as a connecting rod 310 extending along the length of the vehicle body, and the connecting rod 310 can rotate relative to the B-pillar 20 of the vehicle about its axis.
[0054] Furthermore, the first locking part 110 is configured as a first locking hole 111 that passes through the first latch 100 along a direction perpendicular to the axis of the connecting rod 310.
[0055] The second locking part 210 is configured as a second locking hole 211 that passes through the second latch 200 in a direction perpendicular to the axis of the connecting rod 310.
[0056] The first locking hole 111 and the second locking hole 211, located in the first position, both extend in a direction parallel to the horizontal.
[0057] In this embodiment, the connecting rod 310, which extends along the length of the vehicle body, rotates without displacement of the first latch 100 and the second latch 200, thereby changing the orientation angle of the locking hole on the latch. This allows the locking hole to switch between a position aligned with the door lock and a position offset from the door lock. This structure, while satisfying the anti-pinch function during door closing, reduces the space occupied by the latch during position switching, making it more advantageous for the arrangement of this latch device 10 on the B-pillar 20.
[0058] Optionally, in one embodiment, the first latch 100 is configured as a spherical structure, and the first locking hole 111 is eccentrically disposed on the first latch 100; the second latch 200 is also configured as a spherical structure, and the second locking hole 211 is also eccentrically disposed on the second latch 200.
[0059] In this embodiment, the outer wall of the spherical latch is smooth and has no sharp edges, so even if a passenger's limbs accidentally collide with the latch, it is unlikely to cause injury. Furthermore, this spherical structure is more aesthetically pleasing.
[0060] It should be noted that, in order to enable the first latch 100 and the second latch 200 to switch between the first position and the second position together, the first latch 100 and the second latch 200 are symmetrically arranged at both ends of the connecting rod 310. When the first locking hole 111 on the first latch 100 extends in the horizontal direction, the second locking hole 211 on the second latch 200 also extends in the horizontal direction.
[0061] Of course, the shapes of the first latch 100 and the second latch 200 are not limited to spherical structures. In another alternative embodiment, the shapes of the second latch 200 and the second latch 200 can be cuboids, ellipsoids or other irregular shapes. This utility model does not limit them to a single shape.
[0062] Furthermore, in this embodiment, as Figure 2 As shown, the first latch 100 has two first locking holes 111 symmetrically arranged with respect to the axial extension direction of the connecting rod 310; the second latch 200 has two second locking holes 211 symmetrically arranged with respect to the axial extension direction of the connecting rod 310.
[0063] Taking the first latch 100 as an example, when one of the first locking holes 111 on the first latch 100 corresponds to the door lock of the front door, the connecting rod 310 rotates 90 degrees around its axis, and the first locking hole 111 on the first latch 100 is misaligned with the door lock of the front door, so the door cannot be locked. The connecting rod 310 rotates 90 degrees further around its axis, and the other first locking hole 111 on the first latch 100 corresponds to the door lock of the front door, so the door can be locked. The second latch 200 is similar to the first latch 100, and will not be described in detail here.
[0064] In this embodiment, the connecting rod 310 only needs to rotate 90 degrees to switch the latch between the first and second positions.
[0065] Furthermore, such as Figure 4 As shown, both ends of the connecting rod 310 are threaded with threads 311. The first latch 100 and the second latch 200 have mounting holes on the side facing the connecting rod 310 that are adapted to and screwed onto the connecting rod 310. The first latch 100 and the second latch 200 are assembled onto the connecting rod 310 by screwing.
[0066] Of course, in another alternative embodiment, the first latch 100 and the second latch 200 can also be connected to both ends of the connecting rod 310 by means of snap-fit or welding, and the first latch 100 and the second latch 200 can also be integrally formed with the connecting rod 310. This utility model does not make specific limitations in this regard.
[0067] The connection structure between connector 300 and B-pillar 20 is described in detail below.
[0068] Alternatively, in one embodiment, such as Figure 2 and Figure 3 As shown, the locking device 10 also includes a mounting bracket 400, which is fixed to the B-pillar 20 and is used to rotatably mount the connecting rod 310 to the B-pillar 20.
[0069] Furthermore, in order to ensure that the connector 300 can rotate relative to the mounting bracket 400 and the B-pillar 20, a support bearing 500 is provided between the connecting rod 310 and the mounting bracket 400.
[0070] Specifically, such as Figures 2-4 As shown, the mounting bracket 400 includes an arc-shaped connecting section 410 corresponding to the outer wall of the connecting rod 310, and support sections 420 located on both sides of the arc-shaped connecting section 410 extending toward the B-pillar 20 of the vehicle. The bottom of each support section 420 is attached to the surface of the B-pillar 20 of the vehicle and is fixedly connected to the B-pillar 20 of the vehicle by bolts.
[0071] The support bearing 500 includes an outer ring 510, an inner ring 520, and a plurality of rolling elements 530 disposed between the outer ring 510 and the inner ring 520. The number of rolling elements 530 can be seven, eight, ten, or other numbers, and the shape of the rolling elements 530 can be spherical, drum-shaped, cylindrical, or other shapes. This utility model does not make any specific limitation in this regard.
[0072] Specifically, the outer ring 510 of the support bearing 500 is fixedly connected to the inner wall of the arc-shaped connecting section 410 of the mounting bracket 400, and the inner ring 520 of the support bearing 500 is fixedly connected to the outer wall of the connecting rod 310. It should be noted that the outer ring 510 of the support bearing 500 and the mounting bracket 400, and the inner ring 520 of the support bearing 500 and the connecting rod 310, can be connected by welding or interference fit; this utility model does not impose specific limitations on this connection.
[0073] Furthermore, in order to enable the connecting rod 310 to rotate and link the first latch 100 and the second latch 200 to switch between the first and second positions, this latching device 10 also includes a driving member (not shown in the figure) and a transmission member 600. The driving member is mounted on the B-pillar 20 of the vehicle, and the transmission member 600 is connected to the driving member and sleeved on the connecting rod 310. The driving member drives the transmission member 600 to rotate the connecting rod 310 around its axis.
[0074] Optionally, in one embodiment, the driving component is a rotary motor, and the transmission component 600 is a transmission gear 610, which is sleeved on the middle part of the connecting rod 310. Furthermore, the output end of the rotary motor is provided with a drive gear that meshes with the transmission gear 610. The power of the rotary motor is transmitted to the connecting rod 310 through the gear set. This method of transmitting power through gears has high transmission accuracy, ensuring that the first latch 100 and the second latch 200 can switch between the first position and the second position.
[0075] Of course, in another alternative embodiment, a transmission belt is provided between the output end of the rotary motor and the connecting rod 310. One end of the transmission belt is sleeved on the output end of the rotary motor, and the other end is sleeved on the middle of the connecting rod 310. This can also realize the power transmission between the rotary motor and the connecting rod 310. This utility model does not limit this to a single embodiment.
[0076] In an alternative embodiment, instead of rotating the connector 300 via a drive mechanism, the drive mechanism is a linear motor. The output of the linear motor is connected to the connector 300. The linear motor moves the connector 300 along its axial direction, which allows the first latch 100 and the second latch 200 at both ends of the connector 300 to be offset from the corresponding door locks.
[0077] Of course, the connector 300 can also be configured as two racks located on both sides of the rotary motor, with a first latch 100 and a second latch 200 respectively provided at the opposite ends of the two racks, and the adjacent ends of the two racks respectively meshing with the gear at the output end of the rotary motor. The rotary motor can rotate in conjunction with the gear, thereby causing the two racks to move closer to or away from each other, thus realizing the switching of the first latch 100 and the second latch 200 between a first position and a second position. Therefore, this utility model does not limit the specific structure for switching the first latch 100 and the second latch 200 between the first position and the second position.
[0078] like Figure 5 As shown, this utility model also discloses an automobile, including a body, a front door and a rear door connected to the body, and any of the above-mentioned locking devices 10 for automobiles.
[0079] This type of car integrates the front door latches and the rear door latches together through the aforementioned latch device 10. The front door latches and the rear door latches can switch positions in a consistent manner. This allows one of the front or rear doors, which are both in the open state, to have an anti-pinch process before locking because the position of the latch is misaligned with the corresponding door lock. The door can only be locked when the position of the latch is aligned with the corresponding door lock, thus improving the safety of the car.
[0080] Specifically, in one embodiment, an alarm is installed on the B-pillar 20 of the vehicle. Both the alarm and the drive mechanism of the latch device 10 are communicatively connected to a controller that controls the locking and unlocking of the doors. When the front and rear doors are closed, the first and second latches are necessarily in the first position (see...). Figure 2 Taking opening the front door as an example, when the front door lock is unlocked and the front door opens, the rear door is in a closed state. Therefore, the first latch 100 and the second latch 200 are still in the first position. If the rear door lock is unlocked and the rear door also opens, then both the front and rear doors are in the open state. In this case, the controller controls the drive component to drive the connecting component 300 to move, causing the connecting rod 310 to rotate 90 degrees. The first latch 100 and the second latch 200 move from the first position to the second position (see...). Figure 3 ).
[0081] Taking closing the front door as an example, before closing the door, both the front and rear doors are in the open state. The first latch 100 and the second latch 200 of the latching device 10 are both in the second position. At this time, when the user manually pushes the front door to close, the front door lock will first strike the outer wall of the first latch 100, triggering the alarm. The alarm will sound and last for about 5 seconds to remind the rear passengers to avoid getting their hands caught. Then, the controller controls the drive component to drive the connecting component 300 to move, causing the connecting rod 310 to rotate 90 degrees. The first latch 100 and the second latch 200 move from the second position to the first position, and the front door lock will be locked by the first locking hole 111, completing the closing of the front door. The process of closing the rear door is similar and will not be described in detail here.
[0082] Optionally, in one embodiment, the front door of this car is a swing door, and the rear door is a sliding door. It should be noted that this invention does not specifically limit the structure of the front and rear doors, as long as the corresponding locking structures for both the front and rear doors are located on the B-pillar 20.
[0083] It should be noted that, in addition to the specific embodiments described above, those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
