Description

Technical Field

[0001] This invention relates to the field of projection device technology, and more specifically, to a projection device for use in automobile interiors. Background Technology

[0002] A car projection device is a device that projects a signal onto the ground when the car owner opens the car door, indicating the location of the operation. Its purpose is to facilitate the operation of the car door. For example, a car projection device is usually installed at the bottom of the car door. When the user approaches the car door, the car projection device is turned on, and when the car door is opened or closed, the car projection device is turned off.

[0003] The car projection system mainly consists of a projector, control box, vibrator, and audio system.

[0004] Most in-car projection devices on the market are currently bolted on. If a malfunction occurs and repair or replacement is needed, specialized tools are required. The disassembly and assembly methods are often cumbersome, causing inconvenience to staff and easily damaging the device or other parts inside the car during disassembly. For example, to remove screw-fixed projection devices, a specific screwdriver is required. Improper operation can easily strip the screws, making the device difficult to disassemble or even damaging the outer casing. Therefore, we propose a projection device for in-car use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a projection device for automobile interiors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a projection device for use inside a car, comprising a connection component and a projection component;

[0007] The projection component is connected inside the connecting component, which has both an active disassembly / reassembly mode and a passive disassembly / reassembly mode for the projection component.

[0008] The connecting component includes a mounting base, and the projection component includes a projection body connected within the connecting component.

[0009] Preferably, the fixed base has two symmetrical connecting slots inside, and two symmetrical motors are installed inside the fixed base.

[0010] Preferably, an electromagnet is installed at the power drive end of the motor, and a lead screw is movably connected inside the fixed base via a bearing. A synchronous pulley is installed at one end of the lead screw, and the electromagnet corresponds to the synchronous pulley.

[0011] Preferably, the lead screw is externally connected to a connecting seat, the bottom of which is fitted with a sliding plate. The fixed seat has a groove inside, and the sliding plate is slidably connected inside the groove. The fixed seat has two symmetrical connecting frames inside.

[0012] Preferably, each of the two connecting brackets is connected to a connecting bracket two, a locking block is installed on one side of the connecting bracket two, and two symmetrical connecting brackets three are connected to the top of the connecting seat. The connecting brackets three are connected to the connecting bracket two, and a through groove is opened inside the fixing seat.

[0013] Preferably, a slide is connected inside the through groove, and a connecting shaft is movably connected inside the slide via a bearing. A handle and a timing wheel are respectively installed at both ends of the connecting shaft, with the handle located on the front side of the fixed seat.

[0014] Preferably, a timing belt is fitted around the outside of both timing pulley 2 and timing pulley 1. The timing belt is elastic, and the slide, timing pulley 2, and timing pulley 1 are all made of iron.

[0015] Preferably, magnet one and magnet two are installed inside the fixed base and at both ends of the slide, and the slide is attracted to magnet one and magnet two respectively.

[0016] Preferably, a connecting plate is installed on the top and bottom of the projection body. The connecting plate has a slot inside, a connecting column is installed inside the slot, and two symmetrical slots are opened on the outside of the connecting column.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. When in use, this invention features an active disassembly and assembly mode. The motor drives an electromagnet to attract a synchronous wheel, which in turn drives a lead screw to rotate, causing the connecting seat to move and controlling the locking block to engage or disengage from the projection component's slot. Compared to traditional projection devices that use bolts for installation, require specialized tools, and are cumbersome to operate, this mode achieves automated disassembly and assembly. Workers only need to start the motor to complete the installation or disassembly of the projection component, greatly saving time and manpower and improving work efficiency.

[0019] 2. When using this invention, if the active disassembly and assembly mode cannot be used due to special circumstances such as power outages, the passive disassembly and assembly mode of this invention can be used. The operator only needs to move the slide block to attract the magnet, so that the timing belt is taut, and then manually turn the handle to drive the timing pulley to rotate through the timing belt, thereby realizing the disassembly and assembly of the projection component. This manual operation method does not rely on electricity, provides a reliable solution for disassembly and assembly in special circumstances, and enhances the practicality and adaptability of the device.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] As attached Figure 1-8 The projection device shown for use inside a car includes a connection component 1 and a projection component 2;

[0031] The projection component 2 is connected inside the connecting component 1. The connecting component 1 is equipped with an active disassembly / reassembly mode and a passive disassembly / reassembly mode for the projection component 2.

[0032] The connecting assembly 1 includes a fixed base 11, with two symmetrical connecting slots 12 inside the fixed base 11. Two symmetrical motors 13 are installed inside the fixed base 11, and an electromagnet 14 is installed at the power drive end of the motor 13. A lead screw 16 is movably connected inside the fixed base 11 via a bearing. A synchronous pulley 15 is installed at one end of the lead screw 16. The electromagnet 14 corresponds to the synchronous pulley 15. A connecting base 17 is connected to the outside of the lead screw 16. A sliding plate 18 is installed at the bottom of the connecting base 17. A sliding groove 19 is opened inside the fixed base 11, and the sliding plate 18 is slidably connected inside the sliding groove 19.

[0033] The fixed base 11 is fixedly installed at the required installation position. The connecting base 17 is slidably connected to the sliding groove 19 inside the fixed base 11 through the sliding plate 18, so that when the connecting base 17 moves, it moves in a straight line. When the electromagnet 14 is energized and attracts the synchronous wheel 15, the motor 13 can drive the synchronous wheel 15 to rotate, thereby driving the lead screw 16 to rotate.

[0034] The fixed base 11 has two symmetrical connecting brackets 110 inside, and each connecting bracket 110 is connected to a connecting bracket 111. A locking block 112 is installed on one side of the connecting bracket 111. The top of the connecting base 17 has two symmetrical connecting brackets 113, which are connected to the connecting brackets 111. The fixed base 11 has a through groove 114 inside, and a slide 116 is connected inside the through groove 114. A connecting shaft 117 is movably connected inside the slide 116 via a bearing. A handle 118 and a second synchronous pulley 119 are respectively installed at both ends of 17. The handle 118 is located on the front side of the fixed base 11. The outer sides of the second synchronous pulley 119 and the first synchronous pulley 15 are covered with a synchronous belt 122. The synchronous belt 122 is elastic. The slide 116, the second synchronous pulley 119 and the first synchronous pulley 15 are all made of iron. Inside the fixed base 11 and at both ends of the slide 116, a magnet 120 and a magnet 21 are respectively installed. The slide 116 is attracted to the magnet 120 and the magnet 211 respectively.

[0035] When the slide 116 is attracted to the magnet 120, the timing belt 122 is in a slack state. At this time, the motor 13 can be started to adopt the active disassembly and assembly mode. Since the timing belt 122 is in a slack state, the rotation of the timing pulley 15 will not drive the timing pulley 119 to rotate through the timing belt 122. When the slide 116 is attracted to the magnet 121 and the electromagnet 14 is de-energized, the timing belt 122 is in a taut state. At this time, the passive disassembly and assembly mode is adopted. When the handle 118 is manually rotated, the handle 118 drives the timing pulley 119 to rotate through the connecting shaft 117. At this time, the timing pulley 15 is driven to rotate through the timing belt 122.

[0036] The projection assembly 2 includes a projection body 21 connected to the connection assembly 1. The top and bottom of the projection body 21 are equipped with a connecting plate 22. The inside of the connecting plate 22 is provided with a slot 23. A connecting post 24 is installed inside the slot 23. Two symmetrical slots 25 are provided on the outside of the connecting post 24.

[0037] Working principle of the invention: The device mainly consists of a projector (projection component 2), a control box (integrated into the control and drive part of the connecting component 1), a vibrator (which can be externally connected or integrated into a specific part, depending on the actual design, to enhance the tactile feedback of the scene), and a speaker (which can be externally connected or integrated into the device, responsible for audio output); among which, the connecting component 1 serves as the core support and connection structure, enabling reliable installation and convenient disassembly and assembly of the projection component 2;

[0038] When the projection component 2 needs to be installed, the projection body 21 is placed into the fixing base 11, so that the slot 25 corresponds to the block 112. Then, the motor 13 in the fixing base 11 is started. The power drive end of the motor 13 drives the electromagnet 14 to rotate. The electromagnet 14 generates magnetism when energized, attracting the synchronous wheel 15, which is also made of iron. The synchronous wheel 15 is tightly connected to the electromagnet 14 and rotates with it. The rotation of the synchronous wheel 15 drives the lead screw 16 to rotate. The rotation of the lead screw 16 will cause the connecting base 17 to move linearly along the axis of the lead screw 16. When the connecting base 17 moves, it drives the connecting frame 111 through the connecting frame 113, thereby moving the block 112. The connecting frame 110 plays a supporting and connecting role until the block 112 is inserted into the slot 25, and the projection component 2 can be firmly installed in the connecting component 1.

[0039] When it is necessary to disassemble the projection assembly 2, start the motor 13 again. The motor 13 drives the electromagnet 14 to rotate in the opposite direction. The electromagnet 14 attracts the synchronous wheel 15 and makes it rotate. The synchronous wheel 15 drives the lead screw 16 to rotate, causing the connecting seat 17 to move. The connecting seat 17 drives the locking block 112 to exit from the slot 25 through the connecting frame 3 113 and the connecting frame 2 111. At this time, the projection assembly 2 can be taken out from the connecting assembly 1, and the disassembly operation is completed.

[0040] When under special circumstances (such as power outage requiring disassembly and assembly), and a passive disassembly and assembly mode is required, the electromagnet 14 is de-energized. The projector body 21 is placed into the fixed base 11, so that the slot 25 corresponds to the block 112. The slide 116 is moved and attracted to the magnet 121, so that the timing belt 122 is taut. Then, the user manually rotates the handle 118. The handle 118 drives the timing wheel 119 to rotate through the connecting shaft 117. The rotation of the timing wheel 119 drives the timing wheel 15 to rotate through the timing belt 122. The timing wheel 15 drives the lead screw 16 to rotate. The connecting base 17 moves along the axis of the lead screw 16. The block 112 is positioned in the slot 25 by the setting of the connecting bracket 113 and the connecting bracket 111. At this time, the installation is completed. Conversely, when disassembling, the handle 118 is rotated in the opposite direction to disengage the block 112 from the slot 25 to complete the disassembly.

[0041] When not manually rotated, slide 116 is moved and attracted to magnet 120, at which time synchronous belt 122 is in a slack state.
