[0004] However, the current electric vehicle instrument panel has the following problems: the existing instrument panel backlight device does not have a light-focusing isolation component around it, which reduces the effect of the backlight device when it is displaying, consumes more power, and affects the energy efficiency of the electric vehicle. Therefore, we propose an electric vehicle instrument panel backlight brightness adjustment device. Utility Model Content
[0005] The purpose of this invention is to provide an electric vehicle instrument panel backlight brightness adjustment device, which can solve the problem that existing instrument panel backlight devices in the related technology do not have a light-focusing isolation component around them, resulting in reduced display effect when the backlight device is in operation, and the backlight consumes more power, affecting the energy efficiency of electric vehicles.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] An electric vehicle instrument panel backlight brightness adjustment device includes a base plate, an outer frame fixedly connected to the top of the base plate, a cover plate fixedly connected to the top of the outer frame, a light-emitting element fixedly connected to the top of the base plate, a partition device provided on the top of the base plate, the partition device including a column, the bottom of the column fixedly connected to the top of the base plate, a sliding plate slidably connected to the circumferential surface of the column, a pressing component provided on the side of the sliding plate, and a barrier plate fixedly connected to the side of the sliding plate.
[0008] The pressing assembly includes a short rod, which is fixedly connected to the side of the slide plate. The short rod passes through and slides on the side of the outer frame, and a protrusion is fixedly connected to the end of the short rod away from the slide plate.
[0009] A gap is provided between the barrier plate and the light-emitting element, and a spring is provided between the protrusion and the outer frame.
[0010] The barrier plate is provided with a clamping device on its side. The clamping device includes a clamping plate. The side of the clamping plate is fixedly connected to the side of the barrier plate. The side of the clamping plate has a slot. A sliding rod is slidably connected through the side of the outer frame. A round block is fixedly connected to the end of the sliding rod away from the outer frame. An inclined block is fixedly connected to the end of the sliding rod away from the round block.
[0011] A second spring is provided between the inclined block and the outer frame, and the end of the card plate near the inclined block is set with an inclined surface.
[0012] The card plate is in contact with the inclined block, and the slot is located on the movement trajectory of the inclined block.
[0013] The technical effects achieved by this utility model are as follows:
[0014] This utility model, through the setting of a partition device, enables the column, sliding plate, short rod, protrusion, spring, and barrier plate to work together. When the operator presses the protrusion, the movement of the protrusion drives the movement of the short rod, the movement of the short plate drives the movement of the sliding plate, and the movement of the sliding plate drives the movement of the barrier plate. The movement of the barrier plate covers the light-emitting element, avoiding the lack of a focusing partition component around the backlight device of existing instruments, which leads to a decrease in the display effect of the backlight device when it is performing display work, consumes more power, and affects the energy efficiency of electric vehicles.
[0015] This utility model, through the setting of a clamping device, enables the clamping plate, slot, sliding rod, round block, spring two, and inclined block to cooperate. Simultaneously, the movement of the barrier plate drives the movement of the clamping plate, which in turn drives the movement of the slot. The movement of the clamping plate causes the inclined block to move towards the outer frame, compressing spring two. When the slot moves to the inclined block, spring two resets through its own elasticity, thereby driving the inclined block to reset and snap into the slot. This ensures that the barrier device will not shift due to the movement and bumps of the electric vehicle when effectively focusing and blocking light. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0024] like Figures 1-5 As shown, an electric vehicle instrument backlight brightness adjustment device includes a base plate 1, an outer frame 2 fixedly connected to the top of the base plate 1, a cover plate 3 fixedly connected to the top of the outer frame 2, a light-emitting element 4 fixedly connected to the top of the base plate 1, a partition device 5 provided on the top of the base plate 1, the partition device 5 including a column 51, the bottom of the column 51 fixedly connected to the top of the base plate 1, a slide plate 52 slidably connected to the circumferential surface of the column 51, a pressing component provided on the side of the slide plate 52, a blocking plate 56 fixedly connected to the side of the slide plate 52, the pressing component including a short rod 53, the short rod 53 fixedly connected to the side of the slide plate 52, the short rod 53 passing through and sliding on the side of the outer frame 2, a protrusion 54 fixedly connected to the end of the short rod 53 away from the slide plate 52, a gap provided between the blocking plate 56 and the light-emitting element 4, and a spring 55 provided between the protrusion 54 and the outer frame 2 for resetting the short rod 53 and the slide plate 52;
[0025] According to the above structure, when the worker presses the protrusion 54, the movement of the protrusion 54 causes the short rod 53 to move, the movement of the short rod 53 causes the slide plate 52 to move, the movement of the slide plate 52 causes the barrier plate 56 to move, and the movement of the barrier plate 56 covers the light-emitting element 4, thus avoiding the lack of a light-focusing barrier component around the existing instrument backlight device, which would reduce the effect of the backlight device when it is displaying, consume more power, and affect the energy efficiency of the electric vehicle.
[0026] like Figures 1-5 As shown, a clamping device 6 is provided on the side of the barrier plate 56. The clamping device 6 includes a clamping plate 61. The side of the clamping plate 61 is fixedly connected to the side of the barrier plate 56. A slot 62 is opened on the side of the clamping plate 61. A sliding rod 63 passes through and slides on the side of the outer frame 2. A round block 64 is fixedly connected to the end of the sliding rod 63 away from the outer frame 2. An inclined block 66 is fixedly connected to the end of the sliding rod 63 away from the round block 64. A spring 65 is provided between the inclined block 66 and the outer frame 2. The end of the clamping plate 61 near the inclined block 66 is inclined. The clamping plate 61 is in contact with the inclined block 66. The slot 62 is located on the movement trajectory of the inclined block 66. When the inclined block 66 is locked in the slot 62, it is locked to prevent displacement.
[0027] According to the above structure, the movement of the barrier plate 56 simultaneously drives the movement of the clamping plate 61, which in turn drives the movement of the slot 62. At the same time, the movement of the clamping plate 61 causes the inclined block 66 to move towards the outer frame 2, compressing the second spring 65. When the slot 62 moves to the inclined block 66, the second spring 65 resets due to its own elasticity, thereby causing the inclined block 66 to reset and snap into the slot 62. This ensures that the barrier device will not be displaced due to the movement and bumps of the electric vehicle when it effectively focuses light and blocks light.
[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
