Description

Technical Field

[0001] The invention relates to the field of automobile switches, and in particular to a lumbar support switch integrating four-way adjustment and massage functions. Background Art

[0002] At present, most cars are equipped with electric seats, and the position of the electric seats is adjusted by a four-way adjustment switch, so that the driver can be in a more comfortable state. At the same time, the electric seat generally also has a massage function, which can relieve the driver's fatigue during long-term driving and greatly increase the comfort and driving experience. In the prior art, the four-way adjustment switch and the massage trigger switch are often produced separately and installed separately in the car. If the two can be combined and produced in a unified manner, it can not only reduce the production cost, but also facilitate the driver's convenient operation. However, as a mature overall structure, the four-way adjustment switch has the difficulty of integrating the massage trigger switch on it.

[0003] At the same time, the four-way adjustment switch can be used for large current or small current, and has the characteristics of large stroke and metallic texture, while the massage touch switch is generally used for small current. How to combine large current and small current without interfering with each other also has technical difficulties. Especially after the four-way adjustment switch and the massage function switch are combined, the mutual interference between the structures of the two may cause inaccurate triggering and failure, or inconvenience in operation after the combination. Summary of the invention

[0004] The purpose of the present invention is to provide a lumbar support switch integrating four-way adjustment and massage functions, which can integrate the massage trigger function on the four-way adjustment switch, and has the advantages of simplified production process, reasonable structure, and high convenience in operation.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A waist support switch with four-way adjustment and massage functions, comprising:

[0006] The shell as a load-bearing structure;

[0007] A waist support button and a massage button are arranged on the surface of the housing for the user to apply force with his hands;

[0008] A swinging member is arranged in the housing and linked with the waist support button, and swings in any one of the four directions according to the force direction of the waist support button;

[0009] A pressing member is arranged in the shell body and is linked with the massage button and is pressed down as the massage button is subjected to force; the pressing member includes an inner shell and a pressing rod, the pressing rod is fixedly arranged with the inner shell and is pressed down synchronously with the inner shell, a swing hole is opened on the inner shell, and the swing member extends into the inner shell through the swing hole;

[0010] A circuit board is arranged in the housing, the circuit board is located at the lower end of the inner housing and is provided with a waist support response switch corresponding to the four swinging directions of the swinging member and triggered as the swinging member swings in any direction; the circuit board is also provided with a massage response switch corresponding to the position of the pressing rod and triggered as the pressing rod is pressed downward;

[0011] And a conversion component is arranged in the shell and used to cut off the connection between the inner shell and the downward pressure on the inner shell caused by the swinging member squeezing the inner shell when the swinging member swings.

[0012] A further configuration is that the conversion component is a conversion plate, which is located above the inner shell and is arranged on the swinging member to swing synchronously with the swinging member, and active force blocks are fixedly arranged at one end of the conversion plate facing the inner shell corresponding to the four swinging directions of the swinging member, and each of the active force blocks is provided with a first guide surface, and passive displacement blocks corresponding to the positions of each active force block are fixedly arranged above the inner shell, and each of the passive displacement blocks is provided with a second guide surface; as the swinging member swings, when the active force block squeezes the passive displacement block, the active force block and / or the passive displacement block will move obliquely along the first guide surface and the second guide surface, thereby reducing the downward displacement of the inner shell.

[0013] A further configuration is that: the active force block is a hemispherical convex point, the first guide surface is arc-shaped, and a first contact that abuts against the passive displacement block is provided on the side of the first guide surface facing the inner shell, the passive displacement block is a prism-shaped or hemispherical convex platform, the second guide surface is oblique or arc-shaped, and a second contact that abuts against the active force block is provided on the side of the second guide surface facing the conversion plate; when the active force block squeezes the passive displacement block, the first contact will first abut against the second contact, and then the first contact will move obliquely along the second guide surface, and the second contact will move obliquely along the first guide surface.

[0014] A further configuration is that a lumbar support sleeve is provided between the lumbar support button and the swinging member, the lumbar support sleeve is sleeved on the upper end of the swinging member, the lumbar support sleeve has a swinging abutment rod directly abutting against the upper end of the swinging member, and the swinging abutment rod drives the swinging member to swing synchronously with the force direction of the lumbar support button; an inner sleeve is sleeved on the upper end of the lumbar support sleeve, the inner sleeve is linked to the massage button, and slides on the outer side of the lumbar support sleeve with the force applied to the massage button.

[0015] A further configuration is that a reset member is arranged in the inner shell, and the reset member will be deformed when the inner shell is pressed downward and has a tendency to reset the pressed inner shell.

[0016] Further configuration is: a lumbar support bracket is arranged below the inner shell, the reset member is arranged on the lumbar support bracket, and a positioning column for positioning the reset member is arranged on the lumbar support bracket, and a positioning groove is arranged on the reset member for the positioning column to extend into to achieve positioning.

[0017] The intentional effects of the present invention are:

[0018] 1. The present invention combines the four-way adjustment switch and the massage function switch together through reasonable planning; the same device is used to simultaneously control the four-way adjustment of the car electric seat and the opening and closing of the massage function, which not only simplifies the production process, but also increases the portability of the installation and reduces the installation space required inside the car, making the layout more convenient.

[0019] 2. In the present invention, a conversion component is provided to eliminate the influence of the downward force caused by applying force to the swinging member on the pressing member; when the user applies force to the swinging member, the swinging member swings and drives the conversion plate to press down the inner shell at the same time. Since the conversion plate and the inner shell are matched through the protrusions and the bosses, the downward displacement of the inner shell caused by the conversion plate is very small, and it moves obliquely through the first guide surface and the second guide surface, thereby avoiding the massage button being triggered incorrectly due to the downward pressure of the inner shell during swinging.

[0020] 3. The first guide surface on the protrusion in the present invention is arc-shaped and can move obliquely when in contact, which has the advantage of high continuity and effectively avoids jitter and jamming caused by irregular points when the protrusion contacts the boss. In addition, the second guide surface on the boss is also limited, so that the coordination of the entire structure is more stable and the downward pressure on the inner shell during swinging is more effectively eliminated.

[0021] 4. In the present invention, the first contact and the second contact are arranged to cooperate with the first guide surface and the second guide surface, and the sliding of a single point can accelerate the oblique movement, that is, the movement rate of the first contact on the second guide surface and the second contact on the first guide surface. In addition, if the first contact and the second contact are not arranged, but the first guide surface and the second guide surface are directly matched, the friction resistance generated between them will undoubtedly be greater than the friction resistance between the first contact and the second guide surface; therefore, by arranging the first contact and the second contact, the friction resistance generated by the matching can be effectively reduced, and the service life can be extended.

[0022] 5. In the present invention, the inner shell is reset by providing a reset member, making the entire structure more reasonable, and the structure and operation of the present invention are simplified through automatic reset, bringing convenience to the driver.

[0023] 6. The massage function switch in the present invention is not limited to the massage function. On the basis of not changing the structure, it can be connected to other external devices through the wires of the circuit board to expand other functions, and has good adaptability to meet various needs. In addition, the structure of the present invention can distinguish and control large current and small current, which effectively avoids interference between them and makes the use state more stable.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figure 1-7 , a lumbar support switch with four-way adjustment and massage functions, including:

[0034] A housing 1 as a load-bearing structure;

[0035] A waist support button 2 and a massage button 3 are arranged on the surface of the housing 1 for the user to apply force with his hands;

[0036] A swinging member 5 is arranged in the housing 1 and is linked with the waist support button 2, and swings in any one of four directions according to the force direction of the waist support button 2;

[0037] A pressing member 4 is arranged in the housing 1 and is linked with the massage button 3 and is pressed down as the massage button 3 is subjected to force; the pressing member 4 includes an inner housing 41 and a pressing rod 42, the pressing rod 42 is fixedly arranged with the inner housing 41 and is pressed down synchronously with the inner housing 41, a swing hole 43 is opened on the inner housing 41, and the lower end of the swing member 5 passes through the swing hole 43 and extends into the inner housing 41;

[0038] A circuit board 6 is arranged in the housing 1, and the circuit board 6 is located at the lower end of the inner housing 41 and is provided with a waist support response switch corresponding to the four swinging directions of the swinging member 5 and triggered as the swinging member 5 swings in any direction; the circuit board 6 is also provided with a massage response switch 61 corresponding to the position of the pressing rod 42 and triggered as the pressing rod 42 is pressed downward;

[0039] And a conversion component is arranged in the shell body 1 and is used to cut off the connection between the inner shell 41 and the downward pressure on the inner shell 41 caused by squeezing the inner shell 41 when the swinging member 5 swings.

[0040] Generally, the present invention is connected to a motor that performs four-way adjustment and massage. When the driver presses the massage button 3 or the lumbar support button 2, the massage response switch 61 and the lumbar support response switch on the circuit board 6 are triggered through the swing member 5 and the pressing member 4. Then, the massage response switch 61 and the lumbar support response switch generate corresponding trigger signals to the motor, so that the motor works to achieve four-way adjustment or massage. This is part of the prior art and will not be elaborated here. It should be further explained that there are four lumbar support switches, which correspond to the four swinging directions of the swing member 5. When the swing member 5 swings, the lumbar support response switch on the side of the direction will be triggered. This is a conventional technology and will not be elaborated here.

[0041] A further configuration is that the conversion component is a conversion plate 7, which is located above the inner shell 41 and is arranged on the swinging member 5 to swing synchronously with the swinging member 5, and an active force block 71 is fixedly arranged at one end of the conversion plate 7 facing the inner shell 41 corresponding to the four swinging directions of the swinging member 5, and each active force block 71 is provided with a first guide surface 72, and a passive displacement block 411 corresponding to the position of each active force block 71 is fixedly arranged above the inner shell 41, and each passive displacement block 411 is provided with a second guide surface 412; as the swinging member 5 swings, when the active force block 71 squeezes the passive displacement block 411, the active force block 71 and / or the passive displacement block will move obliquely along the first guide surface 72 and the second guide surface 412, thereby reducing the downward displacement of the inner shell 41.

[0042] The active force block 71 is further configured as a hemispherical convex point, the first guide surface 72 is arc-shaped, and a first contact 73 that abuts against the passive displacement block 411 is provided on the side of the first guide surface 72 facing the inner shell 41, the passive displacement block 411 is a quadrangular pyramid-shaped or hemispherical convex platform, the second guide surface 412 is oblique or arc-shaped, and a second contact 413 that abuts against the active force block 71 is provided on the side of the second guide surface 412 facing the conversion plate 7; when the active force block 71 squeezes the passive displacement block 411, the first contact 73 will first abut against the second contact 413, and then the first contact 73 will move obliquely along the second guide surface 412, and the second contact 413 will move obliquely along the first guide surface 72.

[0043] A lumbar support sleeve rod 91 is further provided between the lumbar support button 2 and the swinging member 5. The lumbar support sleeve rod 91 is sleeved on the upper end of the swinging member 5. The lumbar support sleeve rod 91 has a swinging abutment rod 911 directly abutting against the upper end of the swinging member 5. The swinging abutment rod 911 drives the swinging member 5 to swing synchronously with the force direction of the lumbar support button 2. An inner sleeve 92 is sleeved on the upper end of the lumbar support sleeve rod 91. The inner sleeve 92 is linked with the massage button 3 and slides on the outer side of the lumbar support sleeve rod 91 with the force of the massage button 3. The inner sleeve 92 squeezes the conversion plate 7 to make it move.

[0044] A further configuration is that a reset member 82 is provided in the inner shell 41. The reset member 82 will deform when the inner shell 41 is pressed down and has a tendency to reset the pressed inner shell 41. The reset member 82 can be made of rubber and has a rubber button thereon.

[0045] A further configuration is that a lumbar support bracket 81 is provided below the inner shell 41, a reset member 82 is provided on the lumbar support bracket 81, and a positioning column 811 for positioning the reset member 82 is provided on the lumbar support bracket 81, and a positioning groove 821 is provided on the reset member 82 for the positioning column 811 to extend into to achieve positioning.

[0046] When the user presses the lumbar support button 2, the lumbar support button 2 drives the inner sleeve 92 to swing, and at the same time the inner sleeve 92 unidirectionally squeezes the conversion plate 7, and the conversion plate 7 moves rightward and downward at the same time. Since the conversion plate 7 and the inner shell 41 are matched by convex points and bosses, the first contact point on the convex point moves obliquely along the second guide surface on the boss. Therefore, the displacement of the inner shell 41 under the downward force of the conversion plate 7 is very small, which can ensure that the massage response switch 61 is not turned on, and only the function of the lumbar support button 2 is realized (the same applies to the other three directions).

[0047] When the user presses the massage button 3, the inner sleeve 92, the conversion plate 7, the inner shell 41, etc. are only acted on downward, so only the massage response switch 61 is turned on, the lumbar support button 2 will not swing, the lumbar support button 2 has no function, and will not be misoperated.

[0048] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
