Description

Technical Field

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

[0002] The electric seat armrest is a common component in the car. The seat armrest is hingedly connected to the seat armrest bracket fixed to the body structure by a shaft, and the motor drive component drives the shaft to rotate, so that the seat armrest rotates between the horizontal position and the vertical position.

[0003] The electric seat armrest is usually in an upright position. When the user needs to put his hands down to rest, the motor drive component drives it to switch to a horizontal position.

[0004] For the rear seats, luggage and other items are usually placed behind the backrests. During driving, if you encounter an emergency situation and need to brake suddenly, the luggage and other items will rush towards the rear seats due to inertia. At this time, the huge impact force from the rear will damage or even destroy the motor drive components used to drive the seat armrests, and there is also a risk of personal injury to the rear seat occupants.

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

[0006] Purpose of the invention: The technical problem to be solved by the present invention is to provide an impact-resistant flip-up electric seat armrest in view of the deficiencies in the prior art.

[0007] In order to solve the above technical problems, the present invention discloses an impact-resistant flip-type electric seat armrest, which comprises:

[0008] An armrest body capable of rotating between a horizontal position and an upright position around a rotation axis; a crank rocker mechanism comprising a crank, a push connecting rod and a swing arm hook, wherein the crank is rotatably mounted on the vehicle body structure around the rotation axis and can swing a certain angle relative to the armrest body, and the armrest body can be driven by the crank to rotate; a crank tail of the crank is hinged to one end of the push connecting rod; a first end of the swing arm hook is hinged to the armrest body, and a second end is connected to the other end of the push connecting rod, and a hook portion extends 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 when the armrest body is in an upright position, at which time the crank is in a maximum swing angle position 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 to the swing arm hook toward the rotation axis; the second end of the swing arm hook is slidably connected to the other end of the push connecting rod.

[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 rod 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 that continues to rotate drives 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 rod 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 and driving the armrest body to rotate toward the upright position by abutting against the second limiting portion of the armrest body, 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, it also includes a coil spring, the coil spring connecting the armrest body and the vehicle body structure; the coil spring is used to generate a rebound force to make the armrest body rotate around the rotation axis and return to the upright position. The second end of the swing arm hook is hinged to the other end of the push connecting rod.

[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 to motion around the rotation axis.

[0018] Specifically, it comprises an upright position limiting member, wherein the upright position limiting member is fixed on the vehicle body structure, and 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 an 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, which is arranged on the upper side of the swing arm hook, and the hinge point between the tension spring and the swing arm hook and the sliding connection between the push link and the swing arm hook are respectively distributed on both sides of the hinge point between the swing arm hook and the armrest body.

[0022] Beneficial effects:

[0023] 1. When the armrest body is in the process of being erected, the motor drive component drives the crank rocker mechanism, so that the swing arm hook moves to the fixed pin position with the positive rotation of the crank and hooks the fixed pin. In this state, when the armrest body is impacted, the armrest body can be rigidly locked by the swing arm hook and the fixed pin, and the impact force can be absorbed by the fixed pin and the swing arm hook, avoiding damage to the motor drive component and personal injury to the personnel on the armrest body, 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, so that the swing arm hook swings upward and lifts up with the reverse rotation of the crank, disengaging the fixing pin, and then the crank continues to rotate in the reverse direction to drive the armrest body back to the horizontal position without manual operation.

[0025] 3. The present invention 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 in which a coil spring is provided, the process in which the armrest body rotates from the vertical position to the horizontal position, and the process in which the crank drives the arm hook to get rid of the fixing pin is similar to the process in the embodiment in which an elastic element is provided, except that the armrest body is always driven by the crank during the entire rotation process, and smoothly transitions from the vertical position to the horizontal position. Specifically, thanks to the effect of the coil spring, the crank is always in contact with the first limiting portion of the armrest body, making the armrest body flip downward more smoothly, and avoiding the armrest body being partially unloaded and falling due to gravity during this process. In addition, since a coil spring is used and the elastic element is eliminated, the slide groove on the push rod is changed to a round hole for hinge connection, which makes the processing simpler and reduces the number of parts, thereby reducing the complexity of the structure.

[0044] Example 1

[0045] Electric 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 the shaft 15, and the shaft is driven by the 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 switched to a horizontal position by a motor drive component when the user needs to put down his hands and take a rest. 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 occupants of the rear seats vulnerable to personal injury. Therefore, an embodiment of the present invention 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] Combination Figure 6 As shown, the armrest body 1 can rotate around the rotation axis between a horizontal position and a vertical position. A first limiting portion 9 and a second limiting portion 10 are provided on the armrest body 1.

[0047] Combination Figure 6 As shown, the crank-rocker mechanism includes a crank 5, a push 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 by the crank 5 to rotate. The crank tail end of the crank 5 is hinged to one end of the push 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 through 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 extends a hook portion from a side opposite to the first end. The hook portion is used to accommodate the hook groove opening of the fixing pin 4 generally toward the side of the rotation axis.

[0048] Combination Figure 6 As shown, the fixing pin 4 is fixed to the vehicle body structure 12 and is located at the rear side of the armrest body 1 in the upright position. The fixing pin 4 is used for the hook portion of the swing arm hook 7 to hook 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] Combination 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 connected to the shaft of the crank 5 in a transmission manner.

[0051] In this embodiment, when the armrest body 1 is in the process of being erected, the motor drive component 2 drives the crank rocker mechanism, so that the swing arm hook 7 moves to the fixed pin 4 position with the positive rotation of the crank 5, and hooks the fixed pin 4. In this state, when the armrest body 1 is impacted, the armrest body 1 can be rigidly locked by the swing arm hook 7 and the fixed pin 4, and the impact force can be absorbed by the fixed pin 4 and the swing arm hook 7, avoiding damage to the motor drive component 2 and personal injury to the person on the armrest body 1, and it is safer to use.

[0052] In the present application, the forward rotation refers to the direction of rotation from the horizontal position to the vertical position along the armrest body 1. The reverse rotation refers to the direction of rotation from the vertical position to the horizontal position along the armrest body 1.

[0053] Specifically, when the armrest body 1 is laid flat, the motor driving 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 to separate from the second limit portion 10, and pushes the connecting rod 6 to drive the swing arm hook 7 to swing upward to the first position relative to the armrest body 1 to disengage the fixing pin 4. The crank 5 continues to rotate in the opposite direction, and the crank tail of the crank 5 that continues to rotate 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 vertical position, the motor driving 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. Fig. 9 As shown, the crank 5 whose crank tail abuts against 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 has not yet contacted the fixing 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 fixing pin 4, the crank 5 continues to rotate, and the armrest body 1 is connected to the crank 5. Fig.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 relatively along 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 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, as shown in FIG. 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 a 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 chair armrest includes a horizontal position limiter, which is fixed to the vehicle body structure 12. When the armrest body 1 rotates to the horizontal position, the horizontal position limiter abuts against the armrest body 1 to limit the further reverse rotation of the armrest body 1. The horizontal position limiter is not shown in the figure. The horizontal position limiter can be a chair armrest bracket 3 hinged to the armrest body 1 through an axis.

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

[0058] In another embodiment of the elastic element 8, as Fig.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, and 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 the first embodiment, this embodiment further includes a coil spring 13, and the coil spring 13 connects the armrest body 1 and the vehicle body structure 12. Fig.13 As shown, the coil spring 13 is used to generate a rebound force to make the armrest body 1 rotate around the rotation axis and return to the upright position.

[0061] In this example, different from the sliding connection between the swing arm hook 7 and the pushing link 6 in Embodiment 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 positive 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 rotation axis. Therefore, during the erection of the armrest body 1, the crank 5 always remains in contact with the first limit portion 9 of the armrest body 1. Fig.14 When the armrest body 1 is limited in the upright position by the upright position limiter 11, the motor driving 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 in FIG. Figure 6 shown.

[0063] In the process of the armrest body 1 of this embodiment rotating from the vertical position to the horizontal position, the process of the crank 5 driving the arm hook 7 to get rid of the fixing pin is the same as that of the embodiment 1 without the coil spring 13, except that the armrest body 1 is always driven by the crank 5 during the entire rotation process, and smoothly transitions from the vertical 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 limit portion 9 of the armrest body 1, so that the armrest body 1 can be turned down more smoothly, avoiding the armrest body 1 from being partially unloaded and falling due to gravity during this process.

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

[0065] The present invention provides a thought and method for an impact-resistant flip-up electric seat armrest. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
