Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a button switch device. Background Art

[0002] Car seats often feature a removable tray table on the back for rear passengers. When unfolded, it allows for dining, reading, and other activities. When not in use, it folds back against the backrest, eliminating the need for extra space. A light located above the tray table makes it more convenient for rear passengers, for example, allowing the table to be used normally in the dark.

[0003] In existing car seats, the tray table light switch button and the tray table unlock button are separately set, and the two functions are independent. However, due to the limited installation space on the seat, the two buttons are set separately, which not only affects the appearance but also makes operation cumbersome. Utility Model Content

[0047] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0048] like Figure 1-Figure 4 As shown, the push button switch device of this embodiment is applied to a car seat, wherein a table board 60 is arranged on the back side of the car seat. The table board 60 has an unfolded position state and a folded position state on the car seat (as shown in FIG. Figure 1 As shown), when the table top 60 is switched to the expanded position, it flips downward approximately 90 degrees and is approximately in a horizontal state for use by rear passengers. A lamp is provided on the car seat or on the button switch device. When the table top 60 is in use, turning on the lamp can provide lighting to the table top 60. It should be explained that the main function of the lamp is to provide lighting to the table top 60 to facilitate the rear passengers to use the table top 60, so the lamp can be set on the backrest 6 or integrated into the button switch device. Of course, optimally, the lamp of this embodiment is integrated into the button 4, specifically on the back side of the button 4. By pressing the button 4, the lamp can be controlled to be turned on or off, which is convenient to use.

[0049] like Figure 4-Figure 8 The push button switch device of this embodiment mainly includes: a mounting body 1 , a micro switch 2 , a locking member 3 , a button 4 , a driving bracket 5 , a first elastic member 30 and a second elastic member 40 .

[0050] A microswitch 2 is mounted on the mounting body 1. Specifically, it is removably fixed to the mounting body 1 and electrically connected to the lamp. It is used to control the lamp's on and off. Triggering the microswitch 2 once turns the lamp on, and triggering it again turns the lamp off. A protruding post 20 protrudes from the microswitch 2. The driving bracket 5 can trigger the microswitch 2 by squeezing the protrusion 20.

[0051] The locking member 3 is movably provided on the mounting body 1, and the locking member 3 has an unlocked position state and a locked position state on the mounting body 1; when the table top 60 is in the folded position state and the locking member 3 is in the locked position state, the locking member 3 locks the table top 60 (such as Figure 1-Figure 3 As shown in the figure, there is a lock slot on the table top 60, and a lock tongue 31 extends downward from the locking member 3. When the lock tongue 31 is inserted into the lock slot, the locking member 3 locks the table top 60 in the folded position. When the locking member 3 is switched to the unlocked position, that is, the lock tongue 31 on the locking member 3 retracts and disengages from the lock slot of the table top 60, the lock on the table top 60 is released, and the table top 60 can be switched to the unfolded position. Specifically, the table top 60 can be set to a manual unfolding mode or an automatic unfolding mode. By configuring a motor and a gear set, the automatic unfolding of the table top 60 after being unlocked can be achieved.

[0052] The button 4 is movably provided on the mounting body 1. By pressing the button 4, the user can trigger the micro switch 2 to turn the lamp on or off. The user can also drive the locking member 3 to switch from the locked position to the unlocked position by pressing the button 4.

[0053] In actual use, the push button switch device of this embodiment is equipped with a microswitch 2 and a locking member 3. The microswitch 2 is used to control the turning on and off of the lighting fixture on the table panel 60, and the locking member 3 can lock the table panel 60 in the folded position. The user can trigger the microswitch 2 by pressing the button 4, thereby turning the lighting fixture on or off. The user can also drive the locking member 3 from the locked position to the unlocked position by pressing the button 4, thereby allowing the table panel 60 to be unfolded for use. In other words, this push button switch device integrates the functions of the table panel 60 unlock button and the lighting fixture on / off button, with a high degree of integration, which can save installation space on the car seat and ensure the high aesthetics of the car seat.

[0054] In this embodiment, the drive bracket 5 is movably mounted on the mounting body 1. Specifically, the drive bracket 5 is movable and retractable on the mounting body 1. The button 4 and the locking member 3 both flexibly engage with the drive bracket 5. During use, the user can press the button 4 to activate the drive bracket 5, which in turn triggers the microswitch 2 to turn the lamp on or off. The user can also press the button 4 to activate the drive bracket 5, which in turn activates the locking member 3, switching it from a locked position to an unlocked position.

[0055] Specifically, the button 4 is provided with an inclined wall 42, one on each side of the driving bracket 5. The driving bracket 5 extends a protrusion on each side, and the two inclined walls 42 are respectively movably abutted against the two protrusions, thereby achieving the movable abutment between the driving bracket 5 and the inclined walls 42. When the button 4 is pressed, the button 4 can squeeze the driving bracket 5 through the inclined walls 42, causing the driving bracket 5 to move up and down, thereby causing the driving bracket 5 to trigger the micro switch 2 or drive the locking member 3 to move to the unlocked position.

[0056] The locking member 3 is also mounted on the mounting body 1 in a manner that allows it to be moved upward and downward, allowing it to switch between an unlocked position (downward) and a locked position (upward). A T-shaped guide rail 10 is provided on the mounting body 1. A first T-shaped slot 32 and a second T-shaped slot 51 that are compatible with the T-shaped guide rail 10 are provided on the locking member 3 and the driving bracket 5, respectively. The first T-shaped slot 32 and the second T-shaped slot 51 are slidably connected to the T-shaped guide rail 10, allowing the driving bracket 5 and the locking member 3 to be mounted on the mounting body 1 in a manner that allows them to be moved upward and downward. Furthermore, the driving bracket 5 is located below the locking member 3. A first elastic member 30, preferably a spring, is located between the locking member 3 and the mounting body 1. The first elastic member 30 is located above the locking member 3, with one end of the first elastic member 30 resting against the locking member 3 and the other end resting against the mounting body 1. During use, when the button 4 is pressed to switch the locking member 3 to the unlocked position, the first elastic member 30 is compressed. When the button 4 is released, the first elastic member 30 can drive the locking member 3 to return to the locked position.

[0057] Furthermore, when the button 4 is pressed to turn on the lamp and the locking member 3 is switched to the unlocked position, the table top 60 can be switched to the extended position. After the table top 60 is switched to the folded position, the elastic force of the first elastic member 30 can move the locking member 3 to the locked position, locking the table top 60, and the driving bracket 5 does not move, and the lamp remains on. During use, when the table top 60 is closed, the table top 60 will press the locking member 3 upward. Under the action of the first elastic member 30, the locking member 3 will automatically lock into the locking groove on the table top 60. During this process, since the driving bracket 5 does not move, the micro switch 2 does not move either. The lamp can remain in a constant on state and is not affected by the action of closing the table top 60. It is convenient to use and simple to operate.

[0058] Preferably, two first hooks 41 are provided on the button 4 to prevent it from detaching from the mounting body 1. To ensure aesthetics, the mounting body 1 is provided with a cover 43 through which the button 4 is inserted. Two second hooks 50 are provided on the top of the drive bracket 5 to prevent it from detaching from the mounting body 1 during lifting and lowering.

[0059] A second elastic member 40 is further disposed between the button 4 and the mounting body 1. One end of the second elastic member 40 abuts against the button 4, and the other end abuts against the mounting body 1. A second elastic member 40 is disposed near each end of the button 4. The second elastic member 40 is preferably a spring. When a user presses the button 4, the second elastic member 40 is compressed. When the user releases the button 4, the second elastic member 40 forces the button 4 to return to its original position. In other words, the primary function of the second elastic member 40 is to ensure that the button 4 can be promptly returned to its original position.

[0060] It needs to be explained that when the user presses the button 4 downward to the first position, the button 4 triggers the micro switch 2 to control the lamp to turn on or off. When the user presses the button 4 downward to the second position, the button 4 drives the locking member 3 to switch to the unlocked position state, thereby releasing the lock on the table plate 60. Among them, the distance that the button 4 moves to the second position is farther than the distance that the button 4 moves to the first position. That is, in the process of the user pressing the button 4, the micro switch 2 is first triggered to turn the lamp on or off, and then the locking member 3 is driven to switch to the unlocked position state, thereby releasing the lock on the table plate 60. Specifically, when the user presses the button 4 downward for a distance greater than or equal to 2 mm, the button 4 triggers the micro switch 2. When the user presses the button 4 downward for a distance greater than or equal to 6 mm, the button 4 drives the locking member 3 to move to the unlocked position state.

[0061] The working principle of this push button switch device is:

[0062] In a normal state, the table top 60 is in a folded position, that is, folded on the back side of the backrest 6, and the lamp is in a closed (that is, off) state.

[0063] When the user needs to turn on the lamp, the user can press button 4 downward with a travel of 2 mm. The button 4 pushes the driving bracket 5 against the inclined wall 42, causing the driving bracket 5 to move upward. The driving bracket 5 triggers the micro switch 2, turning on the lamp. However, during this process, the travel of the button 4 is insufficient to drive the locking tongue 31 of the locking member 3 out of the locking groove on the table top 60. Therefore, the locking member 3 does not move to the unlocked position, and the table top 60 remains locked.

[0064] When the user still needs to open the small table 60, the user continues to press downward so that the downward movement stroke of the button 4 is greater than or equal to 6 mm. The button 4 pushes the drive bracket 5 upward through the inclined wall 42, so that the upward movement stroke of the drive bracket 5 is sufficient to drive the lock tongue 31 of the locking member 3 to disengage from the lock groove on the table 60. The locking member 3 releases the lock on the table 60, and the table 60 can be unfolded (that is, switched to the unfolded position).

[0065] When the user needs to fold the table top 60 after using it, the table top 60 moves from the unlocked position to the locked position, and the table top 60 will squeeze the locking member 3 upward. Under the action of the first elastic member 30, the lock tongue 31 of the locking member 3 automatically locks downward into the lock groove on the table top 60, and the locking member 3 locks the table top 60 in the folded position. During this process, the locking member 3 will not drive the driving bracket 5 to move upward, so the lamp remains in a normally on state.

[0066] When the user needs to turn off the lamp, the user presses down the button 4 by about 2 mm, so that the button 4 pushes the driving bracket 5, and the driving bracket 5 triggers the micro switch 2, which controls the lamp to turn off.
