Description

Technical Field

[0001] The utility model relates to an armrest of a car seat, in particular to an impact-resistant flip-type electric seat armrest. Background Art

[0002] Powered armrests are common components in cars. They are hinged to an armrest bracket fixed to the vehicle body structure via a shaft. A motor-driven component rotates the shaft, allowing the armrest to rotate between a horizontal and upright position.

[0003] The electric seat armrests are usually in an upright position. When the user needs to put their hands down to rest, the motor drive component drives them to switch to a horizontal position.

[0004] Behind the rear seats, luggage and other items are often placed. During driving, if the vehicle brakes suddenly due to an emergency, the luggage and other items can be forced toward the rear seats due to inertia. The immense impact from behind can damage or even destroy the motor drive components that power the seat armrests, posing a risk of personal injury to rear seat occupants.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in this field. Utility Model Content

[0006] Purpose of the utility model: The technical problem to be solved by the utility model is to provide an impact-resistant flip-up electric seat armrest in response to the shortcomings of the existing technology.

[0007] In order to solve the above technical problems, the utility model discloses an impact-resistant flip-up electric seat armrest, which includes:

[0008] An armrest body capable of rotating about a rotation axis between a horizontal position and an upright position; a crank rocker mechanism comprising a crank, a push link, and a swing arm hook; the crank being rotatably mounted on the vehicle body structure about the rotation axis and capable of swinging a certain angle relative to the armrest body, and the armrest body being driven to rotate by the crank; a crank tail of the crank being hingedly connected to one end of the push link; a first end of the swing arm hook being hingedly connected to the armrest body, and a second end being connected to the other end of the push link; a hook portion extending from the second end of the swing arm hook from a side opposite to the first end thereof;

[0009] a fixing pin fixed to the vehicle body structure and used for the hook portion of the swing arm hook to hook the armrest body when the armrest body is in an upright position, at which time the crank is at a maximum swing angle and in contact with the armrest body;

[0010] and a motor driving component for driving the crank to rotate.

[0011] Specifically, the armrest body is provided with a first limiting portion and a second limiting portion for limiting the swing angle of the crank relative to the armrest body; the crank tail of the crank is located between the first limiting portion and the second limiting portion of the armrest body.

[0012] Specifically, the first limiting portion and the second limiting portion are arranged on the side of the armrest body.

[0013] Furthermore, an elastic element connects the armrest body and the swing arm hook, and is used to continuously apply a preload force toward the rotation axis to the swing arm hook; the second end of the swing arm hook is slidably connected to the other end of the push link.

[0014] Specifically, during the process of laying the armrest body flat, the crank rotates in the opposite direction relative to the armrest body and separates from the second limit portion of the armrest body, the push-link drives the swing arm hook to swing upward to the first position relative to the armrest body to disengage the fixing pin, and the crank tail of the crank continues to rotate, driving the armrest body to rotate toward the horizontal position by abutting against the first limit portion of the armrest body.

[0015] Specifically, during the erection process of the armrest body, the crank rotates forwardly relative to the armrest body from the position in contact with the first limiting portion to abutting against the second limiting portion of the armrest body, so that the push-link drives the swing arm hook to swing downward to the second position relative to the armrest body; in the process of the crank tail of the crank continuing to rotate, the crank tail drives the armrest body to rotate toward the upright position by abutting against the second limiting portion of the armrest body, and the fixing pin can abut against the hook portion of the swing arm hook, and the swing arm hook swings upward around its hinged end with the armrest body to pass over the fixing pin, and then the swing arm hook swings downward under the action of the pre-tightening force of the elastic element until it is hooked on the fixing pin.

[0016] Furthermore, the invention further comprises a coil spring connecting the armrest body and the vehicle body structure; the coil spring is used to generate a rebound force to rotate the armrest body around the rotation axis and return it to the upright position. The second end of the swing arm hook is hinged to the other end of the push link.

[0017] Specifically, when the motor driving component drives the crank to rotate in the forward direction, the driving speed of the motor driving component is configured to be lower than the speed at which the coil spring drives the armrest body to rotate and return around the rotation axis.

[0018] Specifically, it includes an upright position limiting member, which is fixed on the vehicle body structure. When the armrest body is rotated to the upright position, the upright position limiting member abuts against the armrest body.

[0019] Specifically, the fixing pin is located at the rear side of the armrest body in the upright position.

[0020] In one embodiment of the elastic element, the elastic element is a compression spring, and the compression spring is arranged above the swing arm hook.

[0021] In another embodiment of the elastic element, the elastic element is a tension spring. The tension spring is disposed on an upper side of the swing arm hook, and a hinge point between the tension spring and the swing arm hook and a sliding connection between the push link and the swing arm hook are respectively located on either side of a hinge point between the swing arm hook and the armrest body.

[0022] Beneficial effects:

[0023] 1. When the armrest is being raised, the motor drive unit drives the crank rocker mechanism, causing the swing arm hook to move to the fixed pin position as the crank rotates in the forward direction, hooking the fixed pin. In this state, if the armrest is impacted, the armrest is rigidly locked by the swing arm hook and the fixed pin. The impact force is absorbed by the fixed pin and the swing arm hook, preventing damage to the motor drive unit and personal injury to those on the armrest, making it safer to use.

[0024] 2. When the armrest body is to be released to the horizontal position, the motor drive component drives the crank rocker mechanism, causing the swing arm hook to swing upward and lift up as the crank rotates in the opposite direction, disengaging the fixing pin. Then the crank continues to rotate in the opposite direction to drive the armrest body back to the horizontal position without manual operation.

[0025] 3. The utility model simply controls a set of motor drive components to rotate forward and reverse to simultaneously drive the crank rocker mechanism to achieve the rigid locking and unlocking of the armrest body by the swing arm hook and the fixed pin, and drives the armrest body to rotate and switch between the horizontal position and the vertical position. It has the advantages of simple control method and low hardware cost.

[0026] 4. In the embodiment employing a coil spring, the process by which the crank drives the arm hook to disengage the fixing pin during the armrest's rotation from the upright to the horizontal position is similar to that of the embodiment employing an elastic element. The difference is that the armrest is driven by the crank throughout the entire rotation process, smoothly transitioning from the upright to the horizontal position. Specifically, thanks to the coil spring, the crank maintains constant contact with the first stop of the armrest, ensuring a smooth downward rotation of the armrest and preventing the armrest from partially falling due to gravity. Furthermore, the use of a coil spring and the elimination of an elastic element allow the sliding groove on the push rod to be replaced with a circular hole for articulation, simplifying manufacturing, reducing the number of parts, and lowering the complexity of the structure.

[0044] Example 1

[0045] Power seat armrests are common components in cars. Figures 1 to 3 As shown, the armrest body 1 of the electric seat armrest is hingedly connected to the seat armrest bracket 3 fixed to the vehicle body structure 12 by a shaft 15. The shaft is driven by a motor drive component to rotate, so that the armrest body rotates between the horizontal position and the vertical position with the axis of the shaft as the rotation axis. Figure 1 As shown, the armrest body 1 is usually in an upright position, and is only switched to a horizontal position by the motor drive component when the user needs to rest his hands. Figure 2 As shown. Combined Figure 4 As shown, for the rear seats, luggage and other items are usually placed behind the seat backs 16. Figure 5As shown, during driving, if an emergency situation occurs and emergency braking is required, luggage and other items will suddenly rush towards the rear seats due to inertia. At this time, the huge impact force from the rear will be directly transmitted to the motor drive component 2 used to drive the armrest body 1. The motor drive component 2 includes a motor and a transmission mechanism, which broadly includes a reducer, a gearbox, a worm gear, etc. The shafts and gears in the transmission mechanism of the motor drive component 2 will be damaged or even destroyed by the impact. At the same time, the current motor output torque is not enough to resist large impacts and cannot keep the seat armrest in the upright position, which makes the rear seat occupants vulnerable to personal injury. Therefore, an embodiment of the utility model provides an impact-resistant flip-up electric seat armrest, combined with Figure 6 As shown, it includes an armrest body 1, a crank rocker mechanism, a fixing pin 4, an elastic element 8 and a motor drive component 2.

[0046] Combine Figure 6 As shown, the armrest body 1 can rotate around the rotation axis between a horizontal position and an upright position. A first limiting portion 9 and a second limiting portion 10 are provided on the armrest body 1.

[0047] Combine Figure 6 As shown, the crank-rocker mechanism includes a crank 5, a pushing connecting rod 6 and a swing arm hook 7. The crank 5 is rotatably mounted on the vehicle body structure 12 around the rotation axis and is arranged opposite to the armrest body 1. The crank tail of the crank 5 is located between the first limiting portion 9 and the second limiting portion 10 of the armrest body 1. When the swing arm hook 7 is in a disengaged state from the fixing pin 4, the first limiting portion 9 and the second limiting portion 10 jointly limit the movable space of the crank tail of the crank 5, thereby limiting the swingable angle of the crank 5 relative to the armrest body 1. When the crank 5 abuts against the first limiting portion 9 or the second limiting portion 10, the armrest body 1 is driven to rotate by the crank 5. The crank tail end of the crank 5 is hinged to one end of the pushing connecting rod 6. The first end of the swing arm hook 7 is hinged to the armrest body 1, and the second end is slidably connected to the other end of the push link 6 via a sliding structure. The sliding structure includes a slide groove 14 and a slider that can slide along the slide groove 14. The slide groove 14 can be provided on the swing arm hook 7, and the slider is connected to the push link 6. The second end of the swing arm hook 7 has a hook portion extending from the side opposite the first end. The hook portion has a hook slot opening for accommodating the fixing pin 4, which is generally oriented toward the rotation axis.

[0048] Combine Figure 6 As shown, the fixing pin 4 is fixed to the vehicle body structure 12 and is located behind the armrest body 1 in the upright position. The fixing pin 4 is used to be hooked by the hook portion of the swing arm hook 7 when the armrest body 1 is in the upright position. At this time, the crank 5 contacts and connects the second limit portion 10.

[0049] Combine Figure 6As shown, the elastic element 8 connects the armrest body 1 and the swing arm hook 7 and is in a compressed state. The elastic element 8 is used to continuously apply a preload force to the swing arm hook 7 pointing to the axis of the crank 5, that is, the direction of the rotation axis.

[0050] The motor drive component 2 is used to drive the crank 5 to rotate. Specifically, the output shaft of the motor drive component 2 is in driving connection with the shaft of the crank 5.

[0051] In this embodiment, when the armrest body 1 is being raised, the motor drive unit 2 drives the crank rocker mechanism, causing the swing arm hook 7 to move to the fixed pin 4 position as the crank 5 rotates in the forward direction, hooking the fixed pin 4. In this state, if the armrest body 1 is impacted, the armrest body 1 is rigidly locked by the swing arm hook 7 and the fixed pin 4. The impact force can be absorbed by the fixed pin 4 and the swing arm hook 7, preventing damage to the motor drive unit 2 and personal injury to people on the armrest body 1, making it safer to use.

[0052] In this application, forward rotation refers to the direction of rotation from the horizontal position to the upright position along the armrest body 1. Reverse rotation refers to the direction of rotation from the upright position to the horizontal position along the armrest body 1.

[0053] Specifically, when the armrest body 1 is laid flat, the motor drive component 2 drives the crank 5 to rotate in the opposite direction around the rotation axis. Figure 7 As shown, the crank 5 first rotates in the opposite direction relative to the armrest body 1 and separates from the second limit portion 10, pushing the connecting rod 6 to drive the swing arm hook 7 to swing upward to the first position relative to the armrest body 1 and disengage the fixing pin 4. The crank 5 continues to rotate in the opposite direction, and the crank tail of the crank 5 abuts against the first limit portion 9 of the armrest body 1 to drive the armrest body 1 to rotate toward the horizontal position until the armrest body 1 reaches the horizontal position. Figure 7 shown.

[0054] Specifically, during the process of the armrest body 1 being erected from the horizontal position to the upright position, the motor drive component 2 drives the crank 5 to rotate in the positive direction around the rotation axis. Figure 8 As shown, the crank 5 first rotates forward relative to the armrest body 1 from the position in contact with the first limit portion 9 to abut against the second limit portion 10 of the armrest body 1. During this process, the crank 5 drives the swing arm hook 7 to swing downward to the second position relative to the armrest body 1 by pushing the connecting rod 6. Figure 9 As shown, the crank 5, whose crank tail contacts the second limit portion 10 of the armrest body 1, continues to rotate forward, driving the armrest body 1 to rotate toward the upright position. Before the hook portion of the swing arm hook 7 contacts the fixed pin 4, the crank rocker mechanism and the armrest body 1 remain relatively stationary. When the hook portion of the swing arm hook 7 contacts the fixed pin 4, the crank 5 continues to rotate, and the armrest body 1 is rotated toward the upright position. Figure 10As shown, the fixing pin 4 presses against the hook portion of the swing arm hook 7, and the guide edge of the hook portion of the swing arm hook 7 slides relative to the fixing pin 4. The swing arm hook 7 swings upward around its hinged end with the armrest body 1 and passes over the fixing pin 4. At this time, the armrest body 1 continues to rotate along with the crank 5. Then the fixing pin 4 slides into the hook groove of the hook portion of the swing arm hook 7. The swing arm hook 7 falls and is hooked on the fixing pin 4 under the preload force of the elastic element 8. At this time, the armrest body 1 rotates to the upright position. Figure 6 shown.

[0055] Specifically, combined Figures 6 to 10 As shown, the seat armrest includes an upright position limiter 11, which is fixed to the vehicle body structure 12. When the armrest body 1 rotates to the upright position, the upright position limiter 11 abuts against the armrest body 1 to limit further forward rotation of the armrest body 1.

[0056] It should be understood that the armrest includes a horizontal position stopper secured to the vehicle body structure 12. When the armrest body 1 rotates to the horizontal position, the horizontal position stopper abuts the armrest body 1 to limit further reverse rotation. The horizontal position stopper is not shown in the figures. It can be a seat armrest bracket 3 hinged to the armrest body 1 via an axis.

[0057] In one embodiment of the elastic element 8, as Figure 6 As shown, the elastic element 8 is a compression spring, which is arranged above the swing arm hook 7.

[0058] In another embodiment of the elastic element 8, as Figure 12 As shown, the elastic element 8 is a tension spring. The tension spring can be arranged on the upper side of the swing arm hook 7. The hinge point between the tension spring and the swing arm hook 7 and the sliding connection between the push link 6 and the swing arm hook 7 are respectively distributed on both sides of the hinge point between the swing arm hook 7 and the armrest body 1.

[0059] Example 2

[0060] On the basis of embodiment 1, this embodiment further includes a coil spring 13, which connects the armrest body 1 and the vehicle body structure 12. Figure 13 As shown, the coil spring 13 is used to generate a rebound force to rotate the armrest body 1 around the rotation axis and return it to the upright position.

[0061] In this example, unlike the sliding connection between the swing arm hook 7 and the pushing link 6 in Example 1, the second end of the swing arm hook 7 is hinged to the other end of the pushing link 6 and may not have the elastic element 8.

[0062] Specifically, when the armrest body 1 is in a horizontal position, the coil spring 13 is in an extended state, and the force it continuously provides to the armrest body 1 is in the forward rotation direction. When the motor drive component 2 does not drive the crank 5, the first limit portion 9 of the armrest body 1 always remains in contact with the crank 5. When the motor drive component 2 drives the crank 5 to rotate forward, the drive speed of the motor drive component 2 can be set to be lower than the speed at which the coil spring 13 drives the armrest body 1 to rotate and reset around the axis of rotation. Therefore, during the process of erecting the armrest body 1, the crank 5 always remains in contact with the first limit portion 9 of the armrest body 1, as shown in FIG. Figure 14 When the armrest body 1 is limited in the upright position by the upright position limiter 11, the motor drive component 2 continues to drive the crank 5 to rotate forward, and the crank 5 rotates forward from the position in contact with the first limiter 9 to abut against the second limiter 10 of the armrest body 1, so that the push link 6 drives the swing arm hook 7 to swing downward until it is hooked on the fixing pin 4, as shown. Figure 6 shown.

[0063] During the rotation of the armrest body 1 from the upright position to the horizontal position, the process by which the crank 5 drives the arm hook 7 to disengage the fixing pin is similar to that of the first embodiment without the coil spring 13. The difference is that the armrest body 1 is driven by the crank 5 throughout the entire rotation process, smoothly transitioning from the upright position to the horizontal position. Specifically, thanks to the action of the coil spring 13, the crank 5 is always in contact with the first stop 9 of the armrest body 1, making the downward rotation of the armrest body 1 smoother and preventing the armrest body 1 from partially falling due to gravity during the rotation process.

[0064] In addition, compared with Example 1, the impact-resistant flip-up electric seat armrest of Example 2 does not require an elastic element, and the slide groove 14 on the push link 6 of Example 1 is changed into a round hole, which simplifies processing and reduces the number of parts, thereby reducing the complexity of the structure.

[0065] This utility model provides a concept and method for an impact-resistant flip-up electric seat armrest. There are many methods and approaches to implement this technical solution. The above is only a preferred embodiment of the utility model. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the utility model, and such improvements and modifications should also be considered within the scope of protection of the utility model. Any components not specified in this embodiment may be implemented using existing technologies.
