[0002] Doorplates are a type of directional product commonly used in various industries. Traditional doorplates only serve an identification function, with characters engraved on a board, and their function is singular. As people's demand for decorative and aesthetic purposes increases, single-function doorplates can no longer meet the needs. For hotels, restaurants, conference or exhibition venues, the functional requirements for doorplates are not limited to identification, but also need to have a decorative function. Therefore, it is necessary to design a new type of doorplate with multiple functions, which is not limited to identification but can also be used for decoration. Utility Model Content

[0005] A new type of multifunctional doorplate includes a base, an upper plate, a lower plate, and a projection light. The base is a frame structure with vertically connected components. Inside, there is a partition separating the upper and lower parts, forming an upper cavity with an upward opening and a lower cavity with an downward opening. The upper plate covers the upper cavity and has a slot and a slanted groove. A sign holder with a character structure is detachably inserted into the slot. The projection light is located in the slanted groove and projects onto the back wall. The lower plate is a light-transmitting plate and covers the lower cavity. An LED light strip is adhered to the inner wall of the lower cavity, and the light passes through the lower plate to illuminate the area below the base.
[0006] Furthermore, the card holder has a control panel installed in the upper cavity, through which the LED light strip and the projection light switch are controlled.
[0007] Furthermore, the side wall of the card holder has at least one opening, and a control button is installed in the opening. The control button is connected to the control motherboard to control its operation.
[0008] Furthermore, a battery compartment is provided inside the upper cavity, and a battery for power supply is provided inside the battery compartment.
[0009] Furthermore, the projection lamp is mounted on the inclined groove via a mounting bracket, and the projection lamp is provided with at least one for projecting patterns or characters onto the back wall.
[0010] Furthermore, a breathing light surrounding the control buttons is provided within the opening for indication.
[0011] Furthermore, the mounting base is equipped with a projection adjustment unit, which is used to adjust the size of the pattern or characters projected by the projection lamp and to switch the projection content.
[0012] Furthermore, the character structure of the label holder is a groove-shaped structure with a character LED strip glued inside. A light-transmitting plate is provided on the groove-shaped structure to illuminate the character structure through the character LED strip.
[0013] Furthermore, the back of the plaque holder is provided with a hanging hole for installation and fixation with a hook on the wall.
[0014] Furthermore, the upper plate and the lower plate are glued to the card holder with adhesive, and the lower plate is a frosted acrylic plate.
[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0016] 1. This utility model sets a character structure on the base for identification, and uses a projection lamp to project onto the wall behind the character structure, which has both decorative and display effects. The displayed content can be switched according to needs. The light-transmitting lower plate, together with LED light strips, can brighten the lighting under the lamp base. It has multiple functions and can meet the needs of brightening, decoration and projection in different environments.
[0017] 2. This utility model improves the brightness of character markings by setting character light strips on the character structure and using a light-transmitting plate of the character that is adapted to its structure, making the content of the character structure clearer to the human eye.
[0018] 3. This utility model provides a projection adjustment unit on the projection lamp to switch and adjust the size of the projected pattern or characters, thus meeting the usage needs of different environments. Attached Figure Description

[0027] Example
[0028] Cooperate Figures 1 to 4 As shown, this utility model discloses a multifunctional new doorplate, including a base 1, an upper plate 2, a lower plate 3, and a projection lamp 4. The base 1 is a frame structure with the upper and lower parts connected. It has a partition separating the upper and lower parts, forming an upper cavity with an upward opening and a lower cavity with an downward opening. The upper plate 2 covers the upper cavity and has a slot 21 and a slanted groove 22. A sign holder 23 with a character structure is detachably inserted into the slot 21, preferably fixed by screws. The projection lamp 4 is set in the slanted groove 22 and projects onto the back wall. The lower plate 3 is a light-transmitting plate and covers the lower cavity. An LED light strip is adhered to the inner wall of the lower cavity, and the light passes through the lower plate to illuminate the area below the base 1.
