Description

Technical Field

[0001] The utility model relates to the technical field of door access control, in particular to an integrated waterproof door machine. Background Art

[0002] As a core component of the access control system, the door phone is responsible for ensuring the safety of residents and providing convenient access. Under various environmental conditions, especially outdoors, the door phone faces a variety of climate and environmental challenges, such as rain, moisture, extreme temperatures, etc. In addition, as an important electrical device, the electronic components contained in the door phone will generate a lot of heat when powered on for a long time, which will not only increase the energy consumption of the device, but also may cause the performance of the device to decline, and even affect the life and stability of the device. Therefore, how to effectively solve the waterproof performance and heat dissipation problems of the door phone is an important problem to be solved in this technical field. It is not only related to the durability and reliability of the equipment, but also a necessary condition to ensure the long-term stable operation of the equipment.

[0003] In the prior art, there are many waterproof door phones on the market. These waterproof door phones achieve different degrees of waterproof effects by using sealants, waterproof cotton and other means. Their advantages are that they can work normally in harsh environments and reduce the risk of equipment damage caused by moisture and water. However, these waterproof door phones also have some limitations. For example, Figure 1 As shown, the existing door machine is composed of a panel (i) and a rear shell (ii), and the opening for installing the electrical module is located behind the panel (i) and close to the wall ( Figure 1 In thunderstorms and strong winds, it is easy for rain to penetrate into the sealant or waterproof cotton, which may cause the sealant or waterproof cotton to be soaked by rain for a long time, thus causing the equipment to fail. In addition, most of the existing door machines are made of metal materials for the shell, which ensures the heat dissipation performance of the door machine, but cannot avoid high costs.

[0004] Therefore, it is very necessary to find a door phone solution that can effectively prevent water and dissipate heat while taking into account cost and ease of installation. This can not only improve the durability and reliability of the door phone, but also effectively reduce maintenance costs and reduce safety risks caused by equipment failure, while improving the intelligence and comfort of the living environment. Utility Model Content

[0005] In view of the waterproof and heat dissipation problems existing in the prior art, the utility model proposes an integrated waterproof door phone. Figure 2 As shown in the figure, the door machine consists of three parts: touch screen, body and back panel. The opening for installing the electrical module is moved deeper into the wall ( Figure 2In the second place in the middle (II), the design of this door machine aims to overcome the above-mentioned disadvantages and provide a more reliable waterproof and heat dissipation solution; in other words, the present utility model strives to reduce the installation difficulty and cost while ensuring high-quality waterproof performance, and enhance the heat dissipation efficiency of electrical components, so as to ensure the long-term stable operation and high-performance performance of the door machine.

[0006] To achieve the above object, the technical solution adopted by the present utility model is: the door machine includes a touch screen, a body, and a back plate. The body includes an integrally formed front part and a rear part. An installation cavity is provided in the rear part. The front part is adapted to the touch screen, and the rear part is adapted to the back plate. Heat dissipation fins are also provided on the back plate. Both the body and the back plate are made of thermosetting plastics.

[0007] Based on the above, the structural combination of the touch screen, the body, and the back plate is essentially to improve the opening for installing the electrical module deeper into the wall, thereby reducing the probability of water source pouring into the interior of the door machine from outside the wall in extreme weather; the body is made by an integrally formed process, which can ensure that there is no gap between the front part and the installation cavity, further enhancing the waterproof performance of the door machine; the setting of the heat dissipation fins can ensure that the heat generated by the electrical module during long-term operation can be effectively dissipated through the heat dissipation fins, thereby maintaining the stability of the temperature inside the door machine and prolonging the service life of the electrical components; in addition, thermosetting plastics have a high cost performance. Selecting such materials to make the body and the back plate can reduce production costs while ensuring sufficient mechanical strength and durability. Thermosetting plastics also have good processing performance and can be quickly formed by injection molding, etc., which is beneficial to improving production efficiency and reducing manufacturing costs.

[0008] Further, a buried box bayonet is provided at the upper end of the front part, a buried box locking port is provided at the lower end of the front part, back plate buckles and back plate studs are provided around the installation cavity, a disassembly port is provided at the bottom of the rear part, and a plurality of rib plates are also provided between the front part and the rear part.

[0009] Based on the above, the design of the buried box bayonet and the buried box locking port can ensure that the door machine is firmly installed in the buried box, ensuring the stability and safety of daily use; the design of the back plate buckles and back plate studs enables the back plate to be quickly installed on the body and firmly locked; the design of the disassembly port facilitates the disassembly of the back plate during maintenance, which can effectively improve the maintenance efficiency; the design of the rib plates can enhance the connection strength between the front part and the installation cavity, which can not only ensure the integrity of the body during the demolding process in production, but also ensure the safety and reliability of the body during use.

[0010] Further, mounting holes adapted to the heat dissipation fins are formed in the back plate. A rib protruding towards the outer surface of the back plate is disposed around the edge of the mounting hole. A back plate bayonet adapted to be snap-fitted with the back plate is disposed around the side edge of the back plate. Back plate screw holes protruding from the outer surface of the back plate are disposed around the outer surface of the back plate. A first groove and a second groove are further formed in the back plate. An air vent hole is formed in the first groove on the side close to the inside of the back plate. A sealing ring groove is formed on the inner surface edge of the back plate. A pry opening is further formed at the bottom of the back plate.

[0011] Based on the above, the design with the inner edge of the mounting hole sunken and the outer edge protruding is beneficial for the heat sink to better fit the back plate, thereby improving the heat dissipation efficiency, and can also effectively prevent rainwater from seeping into the door machine through the opening of the mounting hole. The back plate bayonets disposed around the outer periphery of the back plate are adapted to the back plate snap, which can ensure the tight connection between the back plate and the integrated housing and improve the structural stability of the door machine. The design of the first groove and the second groove enables the water flow to not flow into the installation cavity under the action of gravity. At the same time, the comb-shaped design of the air vent hole further allows air circulation, ensuring the safety and stability of the long-term operation of the electrical module group. The pry opening disposed at the bottom of the back plate enables the back plate to be easily disassembled, facilitating the maintenance or replacement of components.

[0012] Further, a comb-shaped heat dissipation rib is disposed on one side of the heat dissipation fin. The heat dissipation fin is in sealed cooperation with the inner edge of the mounting hole, and the heat dissipation rib faces the outside of the back plate. The height of the heat dissipation rib is less than or equal to the height of the rib.

[0013] Based on the above, the sealed connection between the heat sink and the inner edge of the mounting hole, combined with the design of the comb-shaped structure facing outwards, helps prevent rainwater or other water sources from flowing into the mounting hole along the heat sink, thereby improving the waterproof performance of the door machine. The comb-shaped structure on the heat sink faces outwards, which helps increase the contact area with the outside air, thereby improving the heat dissipation efficiency. At the same time, the height of the protruding outer edge forms a protective effect on the comb-shaped structure, capable of isolating rainwater from flowing along the outer side of the back shell.

[0014] Further, a pre-embedded box snap adapted to the pre-embedded box bayonet is disposed at the upper end of the opening of the pre-embedded box. Ear plates are disposed on both sides of the opening of the pre-embedded box. A locking screw hole adapted to the pre-embedded box locking opening is disposed at the lower end of the opening of the pre-embedded box. A wire management hole is formed on the back of the pre-embedded box.

[0015] Based on the above, the design of the wire management hole helps to organize and hide the wires, increasing the convenience of construction; the pre-embedded box buckle provided at the upper end of the opening of the pre-embedded box is adapted to the pre-embedded box bayonet of the body, ensuring the stability of the connection between the pre-embedded box and the body; the design of the ear plate helps to provide an accurate positioning reference when installing the door machine; the locking screw hole at the lower end of the pre-embedded box can provide a stable connection point, facilitating the fixation of the pre-embedded box and the body, and at the same time improving the stability and durability of the overall structure.
