Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a rear seat armrest with magnetic anti-shake function and an automobile. Background Technology

[0002] Car armrests were originally designed to provide elbow support for passengers, but they have evolved into in-car storage compartments, including armrest panels, facilitating conversations, work, and document viewing. Car armrests are divided into front and rear types. The front armrest is located in the center of the front seats, above the front aisle, providing elbow support for front passengers. The rear armrest is located in the center of the rear seats, and is often retractable, providing elbow room for rear passengers. It can be folded away when not needed, without affecting the sense of space inside the car.

[0003] Currently, rear armrests on the market typically use a low-position locking structure. With this structure, the distance from the armrest end to the armrest pivot is ten to twenty times greater than the distance from the armrest limit pin to the armrest pivot. Due to unavoidable manufacturing and assembly tolerances, even a gap of only about 0.5mm between the limit pin and the armrest bracket's shaft hole, magnified ten to twenty times, can result in a movement gap of over 5mm, or even more than ten millimeters, in the locked state. This means that when the vehicle accelerates or decelerates, or when driving over uneven surfaces, the armrest end will wobble back and forth, producing abnormal noises. This not only affects the comfort of the car seats, making passengers feel the seats lack a premium feel, but also fails to meet the requirements of some high-demand car manufacturers for Freeplay (meaning that the armrest end wobbles back and forth even with a small force when the armrest is closed and locked).

[0004] Therefore, some car seat manufacturers offer two solutions for the rear armrest trim panel: a locking type and an adjuster type. The locking type involves setting a lock assembly on the rear armrest and a pivot pin on the rear seat. The locking and unlocking between the pivot pin and the lock assembly prevents the rear armrest from shaking. The advantages of this structure are its simplicity, stable locking effect, and low cost. However, its disadvantages are also obvious: the lock hole and pivot pin are exposed, resulting in a poor appearance. The adjuster type, on the other hand, uses an adjuster with a built-in locking effect between the armrest and the seat. The advantages of this method are its simple structure, stable locking effect, and good appearance. The disadvantages are that the adjuster mechanism is more expensive and heavier, increasing the manufacturing cost and weight of the rear armrest. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a lightweight, structurally stable, and non-disturbing rear armrest with magnetic anti-shake function for a car, which is in line with the current state of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a car rear armrest with magnetic anti-shaking function is proposed, comprising: an armrest body, which is hinged to the car seat, the armrest body having a pressing position when it is close to the car seat and a maximum unfolded position when it is away from the car seat; The fastening assembly has an electromagnet disposed in the armrest body or the car seat, and a magnetic attractant that attracts the electromagnet when the armrest body is in the abutting position. The fastening assembly has a first working state or a second working state. When the fastening assembly is in the first working state, the handrail body can be fixed in the abutting position because the electromagnet is energized and attracts the magnetic component, and can be switched from the abutting position to the maximum unfolded position because the electromagnet is short-circuited in the circuit. When the fastening assembly is in the second working state, the handrail body can be fixed in the abutting position because the electromagnet is energized and attracts the magnetic component. When the circuit supplying the electromagnet is disconnected and the electromagnet is demagnetized, the handrail body can switch from the abutting position to the maximum unfolded position.

[0007] In the aforementioned vehicle rear armrest with magnetic anti-shake function, the armrest body is provided with a movable first contact and a second contact. The first contact and the second contact are both electrically connected in the circuit. The first contact and the second contact are connected in parallel with the electromagnet, and the first contact and the second contact are normally open.

[0008] The aforementioned vehicle rear armrest with magnetic anti-shake function further includes a first unlocking block. The first unlocking block is movably disposed within the armrest body and elastically connected to the first contact point. The first unlocking block is used to drive the first contact point and the second contact point to separate.

[0009] In the aforementioned vehicle rear armrest with magnetic anti-shake function, a first mounting base is provided in the armrest body, a first elastic element is provided in the first mounting base, a first unlocking block is movably disposed in the first mounting base and the first elastic element abuts against the first unlocking block and the first mounting base, the elastic force of the first elastic element is greater than the elastic force between the first contact and the first unlocking block, the first contact can be separated from the second contact because the first elastic element abuts against the first unlocking block, and when the first unlocking block overcomes the elastic force of the first elastic element, it abuts against the second contact.

[0010] In the aforementioned vehicle rear armrest with magnetic anti-shake function, the armrest body is provided with a movable third contact and a fourth contact, both of which are electrically connected in the circuit. The third contact and the fourth contact are connected in series with the electromagnet and are normally closed.

[0011] The aforementioned rear seat armrest with magnetic anti-shake function further includes a second unlocking block. The second unlocking block is movably disposed within the armrest body and movably abuts against the third contact point. The second unlocking block is used to drive the third contact point and the fourth contact point to separate.

[0012] In the aforementioned vehicle rear armrest with magnetic anti-shake function, a second mounting base is provided within the armrest body, a second elastic element is provided within the second mounting base, a second unlocking block is movably disposed within the second mounting base, and the second elastic element abuts against the second unlocking block and the second mounting base. The third contact point can abut against the fourth contact point because the second elastic element is pressed against the second unlocking block, and separates from the fourth contact point because the second unlocking block overcomes the elastic force of the second elastic element and pushes the third contact point.

[0013] The aforementioned rear seat armrest with magnetic anti-shake function also includes a cover plate connected to the car seat. When the armrest body is in the abutting position, it abuts against the cover plate. The end of the cover plate away from the armrest body is provided with a mounting groove, and the magnetic component is disposed in the mounting groove.

[0014] In the aforementioned type of vehicle rear armrest with magnetic anti-shake function, the armrest body includes: The electromagnet is threaded onto the frame; A buffer layer that wraps around the outside of the skeleton; A covering layer that wraps around the outside of the buffer layer; A decorative frame passes through the covering layer and the buffer layer and is fixed to the first mounting base; A toggle block is slidably disposed within the first mounting base, with one end of the toggle block passing through the decorative frame and exposed on the outside of the armrest body.

[0015] In addition to solving the above-mentioned technical problems, the present invention also proposes a car, including the above-mentioned rear seat armrest with magnetic anti-shake function.

[0016] Compared with the prior art, the present invention has the following main advantages. (1) By setting up electromagnets and magnetic components that attract each other to the electromagnets after they are energized, the rear armrests are prevented from shaking on the car seats. Since the electromagnets and magnetic components are low in manufacturing cost and light in weight, the manufacturing cost of the rear armrests is reduced. Furthermore, the use of electromagnets and magnetic components will not leave any hole-like structures on the surface of the rear armrests and / or car seats, thus not affecting the appearance of the car seats. (2) The setting of the first contact and the second contact, and the parallel setting of the first contact and the second contact with the electromagnet, are used to realize the normal energization of the electromagnet in the circuit, and the short circuit state when the rear armrest needs to be switched to the rotating state. (3) The elastic setting between the first contact and the first unlocking block is used to realize the separation between the first contact and the second contact. The setting of the first unlocking block is used to realize the abutment between the first contact and the second contact, thereby realizing the connection and short circuit of the circuit; (4) The first mounting base and the first elastic element are provided to realize the installation, fixation and reset of the first unlocking block on the handrail body.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1 to 7 In this solution, two embodiments are used to illustrate the specific structure of the vehicle rear armrest and to describe in detail its use in a car. Example

[0021] This solution provides a rear seat armrest with magnetic anti-shake function, comprising: an armrest body 1, which is hinged to the car seat, the armrest body 1 having a pressing position when pressed against the car seat and a maximum unfolded position when away from the car seat; and a fastening assembly having an electromagnet 2 disposed inside the armrest body 1 or on the car seat, and a magnetic attractant 3 that attracts the electromagnet 2 when the armrest body 1 is in the pressing position, the armrest body 1 can be fixed in the pressing position when the electromagnet 2 is energized and attracts the magnetic attractant 3, and can be switched from the pressing position to the maximum unfolded position when the electromagnet 2 is short-circuited in the circuit.

[0022] In this embodiment, the magnetic attractor 3 can be installed on the rear seat of the car, and the electromagnet 2 can be installed on the armrest body 1. Alternatively, the electromagnet 2 can be installed on the rear seat of the car, and the magnetic attractor 3 can be installed on the armrest body 1. The magnetic attractor 3 can be made of iron, cobalt, and nickel metals, or an alloy containing iron, cobalt, and nickel metals. In this solution, the electromagnet 2 can be powered by the vehicle's power supply. The electromagnet 2 is a device that generates electromagnetic fields when energized. A conductive winding matching its power is wound around the outside of the iron core. This current-carrying coil has magnetism like a magnet. The electromagnet 2 is usually made in a bar or horseshoe shape to make the iron core easier to magnetize. In addition, in order to demagnetize the electromagnet 2 immediately by short-circuiting, the iron core is often made of soft iron or silicon steel material that demagnetizes quickly. In this solution, the electromagnet 2 is in a normally energized state. Only when it is necessary to pull the armrest body 1 away from the car seat from the pressed position, the electromagnet 2 is stopped by short-circuiting, thereby allowing the armrest body 1 to be in a free state.

[0023] In this solution, by setting up an electromagnet 2 and a magnetic attractant 3 that attracts the energized electromagnet 2, the rear armrest is prevented from shaking on the car seat. Since the electromagnet 2 and the magnetic attractant 3 are low in manufacturing cost and light in weight, the manufacturing cost and weight of the rear armrest are reduced. Furthermore, the use of the electromagnet 2 and the magnetic attractant 3 will not leave any perforated structures on the surface of the rear armrest and / or the car seat, thus not affecting the appearance of the car seat.

[0024] Furthermore, the handrail body 1 is provided with a movable first contact 4 and a second contact 5, both of which are electrically connected in the circuit. The first contact 4 and the second contact 5 are connected in parallel with the electromagnet 2, and the first contact 4 and the second contact 5 are normally open.

[0025] The setting of the first contact 4 and the second contact 5, and the parallel connection of the first contact 4 and the second contact 5 with the electromagnet 2, are used to realize the normal energization and operation of the electromagnet 2 in the circuit, as well as the short-circuit state when the rear armrest needs to be switched to the rotating state.

[0026] Furthermore, this solution also includes a first unlocking block 6, which is movably disposed within the armrest body 1 and elastically connected to the first contact point 4. The first unlocking block 6 is used to drive the first contact point 4 and the second contact point 5 to separate.

[0027] Preferably, the first unlocking block 6 can be made of plastic or other insulating materials such as wood or insulating rubber. In this solution, the elastic connection between the first unlocking block 6 and the first contact 4 can be achieved by setting a spring sheet structure on the first contact 4. In the initial state, the first unlocking block 6 abuts against the first contact 4, causing the first contact 4 to undergo elastic deformation and disconnect it from the second contact 5. When it is necessary to switch the state of the handrail body 1, the first unlocking block 6 is moved in the direction of restoring the elastic deformation of the first contact 4, removing the pressure applied to the first contact 4, so that the first contact 4 can abut against the second contact 5, thereby short-circuiting the electromagnet 2 in the circuit, and finally allowing the handrail body 1 to be in a free state.

[0028] Furthermore, a first mounting base 7 is provided inside the handrail body 1, and a first elastic element 8 is provided inside the first mounting base 7. A first unlocking block 6 is movably disposed inside the first mounting base 7, and the first elastic element 8 abuts against the first unlocking block 6 and the first mounting base 7. The elastic force of the first elastic element 8 is greater than the elastic force between the first contact point 4 and the first unlocking block 6. The first contact point 4 can be separated from the second contact point 5 because the first elastic element 8 is pressed against the first unlocking block 6, and when the first unlocking block 6 overcomes the elastic force of the first elastic element 8, it abuts against the second contact point 5.

[0029] The first elastic element 8 can be a spring or a rubber product. In the initial state, since the elastic force of the first elastic element 8 is greater than the elastic force between the first contact 4 and the first unlocking block 6, the first elastic element 8 pushes the first unlocking block 6 to overcome the elastic force of the first contact 4 itself, causing the first contact 4 and the first unlocking block 6 to separate, so that the electromagnet 2 is energized in the circuit. When the first unlocking block 6 is pushed towards the first elastic element 8 manually or by using a power device such as a motor or cylinder, the first contact 4 moves towards the second contact 5 until it is pressed against the second contact 5, so that the electromagnet 2 is in a short-circuit state. After the first unlocking block 6 is reset, the first contact 4 is pushed again to separate it from the second contact 5.

[0030] The first mounting base 7 is used for the installation and fixing of the first unlocking block 6 and the first elastic member 8. Preferably, the first mounting base 7 is provided with a guide groove, and the first unlocking block 6 is provided with a guide post. The guide post is movably inserted into the guide groove, thereby ensuring the movement direction of the first unlocking block 6 within the first mounting base 7.

[0031] Furthermore, this solution also includes a cover plate 14, which is connected to the car seat. When the armrest body 1 is in the abutting position, it abuts against the cover plate 14. The end of the cover plate 14 away from the armrest body 1 is provided with a mounting groove 15, and the magnetic component 3 is disposed in the mounting groove 15.

[0032] In this solution, the magnetic component 3 is set on the cover plate 14 fixed on the car seat, the electromagnet 2 is set inside the armrest body 1, and the mounting groove 15 on the cover plate 14 is used for the installation and fixing of the magnetic component 3. Preferably, the magnetic component 3 is snapped into the mounting groove 15.

[0033] Furthermore, the handrail body 1 includes: a frame 16, with an electromagnet 2 threadedly connected to the frame 16; a buffer layer that wraps around the outside of the frame 16; a covering layer 17 that wraps around the outside of the buffer layer; a decorative frame 18 that passes through the covering layer 17 and the buffer layer and is fixed to the first mounting base 7; and a toggle block 19 that is slidably disposed in the first mounting base, with one end of the toggle block 19 passing through the decorative frame 17 and exposed on the outside of the handrail body.

[0034] The threaded connection between the electromagnet 2 and the frame 16 can be achieved by setting a threaded hole on the frame 16 and a bolt through hole on the electromagnet 2, and then connecting the bolt through the bolt through hole to the threaded hole. Alternatively, it can be achieved by setting a bolt through hole on the frame 16 and a threaded hole on the electromagnet 2. The decorative frame 18 is used to cover part of the structure of the first mounting base 7, making the appearance of the handrail body 1 more beautiful and harmonious. The decorative frame 17 is used to cover up the unsightly parts of the handrail body 1 when the toggle block 19 passes through it. Example

[0035] This solution provides a rear seat armrest with magnetic anti-shake function, comprising: an armrest body 1, which is hinged to the car seat, the armrest body 1 having a pressing position when pressed against the car seat and a maximum unfolded position when away from the car seat; and a fastening assembly having an electromagnet 2 disposed inside the armrest body 1 or on the car seat, and a magnetic attractant 3 that attracts the electromagnet 2 when the armrest body 1 is in the pressing position. The armrest body 1 can be fixed in the pressing position when the electromagnet 2 is energized and attracts the magnetic attractant 3, and can switch from the pressing position to the maximum unfolded position when the circuit of the power supply magnet 2 is broken, causing the electromagnet 2 to be demagnetized.

[0036] The working principle of this solution is basically the same as that of Embodiment 1, except that the de-energization of electromagnet 2 is achieved by breaking the circuit.

[0037] Furthermore, the handrail body 1 is provided with a movable abutment third contact 9 and a fourth contact 10. The third contact 9 and the fourth contact 10 are electrically connected in the circuit. The third contact 9 and the fourth contact 10 are connected in series with the electromagnet 2 and are normally closed.

[0038] The setting of the third contact 9 and the fourth contact 10, and the series connection of the third contact 9 and the fourth contact 10 with the electromagnet 2, are used to enable the electromagnet 2 to be energized normally in the circuit, and to have the circuit breaking function when the rear armrest needs to be switched to the rotating state.

[0039] Furthermore, this solution also includes a second unlocking block 11, which is movably disposed within the handrail body 1 and movably abuts against the third contact 9. The second unlocking block 11 is used to drive the third contact 9 and the fourth contact 10 to separate.

[0040] In the initial state of this scheme, the third contact 9 and the fourth contact 10 abut against each other to connect the circuit. The electromagnet 2 fixes the handrail body 1 in the abutting position by attracting the magnetic suction component 3. The second unlocking block 11 abuts against the third contact 9 or does not contact the third contact 9. When it is necessary to switch the state of the handrail body 1, the second unlocking block 11 is pressed towards the third contact 9, causing the third contact 9 to undergo elastic deformation and disengage from the fourth contact 10. At this time, the circuit is disconnected, the electromagnet 2 is demagnetized and no longer attracts the magnetic suction component 3, and the handrail body 1 is in a free state. After the second unlocking block 11 is reset, the third contact 9 moves in the direction of restoring elastic deformation and abuts against the fourth contact 10 again. The electromagnet 2 is energized and can fix the handrail body 1 in the abutting position by attracting the magnetic suction component 3.

[0041] Furthermore, a second mounting base 12 is provided inside the handrail body 1, and a second elastic member 13 is provided inside the second mounting base 12. The second unlocking block 11 is movably disposed inside the second mounting base 12, and the second elastic member 13 abuts against the second unlocking block 11 and the second mounting base 12. The third contact 9 can abut against the fourth contact 10 because the second elastic member 13 is pressed against the second unlocking block 11, and the third contact 9 is separated from the fourth contact 10 because the second unlocking block 11 overcomes the elastic force of the second elastic member 13 and pushes the third contact 9.

[0042] The function of the second mounting seat 12 is the same as that of the first mounting seat 7, and will not be repeated here. In this scheme, the third contact 9 and the fourth contact 10 are normally closed. The second unlocking block 11 and the third contact 9 are abutted or separated, and the second elastic member 13 presses on the second unlocking block 11 to prevent the second unlocking block 11 from shaking in the second mounting seat 12 when the vehicle shakes, so that the second unlocking block 11 pushes the third contact 9 and the fourth contact 10 to separate, thereby ensuring the stability of the rear armrest structure of this scheme.
