[0018] The following is further described in detail through specific implementation methods:

[0019] The reference numerals in the drawings of the specification include: door magnet body 1 , magnetic attraction member 2 , fixing seat 3 , and guide protrusion 31 .

[0020] Example:

[0021] A new type of hidden refrigerated car door magnetic installation structure, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes: a door magnetic body 1, a magnetic attraction component 2 and a fixing seat 3.

[0022] The refrigerated vehicle door frame is provided with a receiving groove for mounting the door magnet body 1. The shape of the receiving groove matches the shape of the door magnet body 1. The door magnet body 1 is fixed to the fixing seat 3. The inner wall of the receiving groove is provided with a guide groove, which is formed by slotting. The fixing seat 3 is provided with a guide protrusion 31 that matches the guide groove. The guide groove provides accurate guidance for the installation of the door magnet body 1, ensuring that the door magnet body 1 does not shift or rotate during installation, ensuring the accuracy and consistency of its installation position. The guide groove and guide protrusion 31 work together to ensure the accuracy of the installation position of the door magnet body 1 within the receiving groove.

[0023] In this embodiment, a groove matching the shape and size of magnetic element 2 is provided at the edge of the door panel. Magnetic element 2 is inserted into the groove. Glue (e.g., strong structural adhesive) or mechanical fasteners (e.g., rivets, screws, etc.) are then used to secure magnetic element 22 within the groove. This ensures that magnetic element 2 is tightly coupled to the door panel and prevents it from falling off or shifting during use. In this embodiment, magnetic element 2 can also be secured within the groove using a fixing base 3.

[0024] The magnetic component 2 and the door magnetic body 1 attract each other, and the magnetic component 2 and the door magnetic body 1 cooperate to control the opening and closing of the refrigerated truck door. The door magnetic body 1 and the magnetic component 2 are hidden by the accommodating slots and grooves, which not only ensures the magnetic function of the refrigerated truck door, but also improves the overall aesthetics and thermal insulation performance of the door, while facilitating installation, maintenance and inspection. The magnetic component 2 and the door magnetic body 1 are both made of strong magnetic materials to ensure a reliable sealing effect when the door is closed. In this embodiment, the magnetic component 2 and the door magnetic body 1 are relatively arranged on the corresponding refrigerated truck door and door frame, and can also be arranged left and right or multiple groups of magnetic components 2 and door magnetic bodies 1 according to actual conditions. In this embodiment, the magnetic component 2 and the door magnetic body 1 can also be electromagnets, and the magnitude of the magnetic force is controlled by a corresponding controller. The specific electromagnet structure and control method are all existing technologies and are not described in detail here.

[0025] A sealing strip is also provided between the door and the door frame of the refrigerated truck. The sealing strip is fixed to the door frame to further enhance the sealing effect and hide the installation traces of the door magnetic assembly. The sealing strip is made of elastic material to ensure that it can fit tightly to the door frame when the door is closed to form a continuous sealing surface. The sealing strip is specifically a rubber sealing strip.

[0026] The surface of the door magnet body 1 and the magnetic attraction member 2 are both provided with an anti-corrosion layer to improve their service life and durability.

[0027] The lower portion of the refrigerated truck door frame features a drain hole connected to the receiving groove. This ensures that any accumulated water can be drained away without compromising the overall structural strength and thermal insulation of the door frame due to excessive size. The drain hole is angled to allow for the natural drainage of accumulated water, preventing it from accumulating in the receiving groove and potentially causing rust or other damage to the door sensor body 1.

[0028] The opening of the receiving slot is provided with a cover plate, which is detachably connected to the receiving slot. The cover plate is used to protect the door magnet body 1 to prevent dust and other impurities from entering the receiving slot and causing damage to the door magnet body 1. The detachable connection ensures that the cover plate is securely installed and easy to remove, so that it can be easily opened when maintenance or inspection of the door magnet body 1 is required. The area of ​​the cover plate is larger than the opening area of ​​the receiving slot, and the cover plate is fixed to the door frame with screws. In this embodiment, the cover plate is made of a material that does not affect the mutual attraction between the magnetic element 2 and the door magnet body 1.

[0029] A seal is installed at the opening edge of the receiving groove. The seal is a rubber sealing strip with a ring or rectangular cross-section that matches the opening edge of the receiving groove. The seal prevents impurities such as moisture and dust from entering the receiving groove and damaging the door sensor body 1.

[0030] The fixing seat 3 is fixed in the receiving groove by bolts, specifically by multiple bolts. The number and position of the bolts are determined according to the actual size of the door magnet body 1 and the size of the receiving groove. When tightening the bolts, the operation should be carried out in a certain order and torque to prevent the fixing seat 3 from being deformed or the door magnet body 1 from being installed loosely due to uneven tightening of the bolts, such as installing it in a top-to-bottom order. A threaded through hole is provided on the door magnet body 1. The bolt passes through the threaded hole on the fixing seat and the threaded through hole of the door magnet body 1 and is fixed in the receiving groove. By rotating the nut of the bolt, the relative position of the door magnet body 1 on the screw of the bolt is adjusted, thereby driving the door magnet body 1 to adjust its front and rear position in the receiving groove, ensuring that the magnetic attraction component 2 and the door magnet body 1 can achieve good magnetic attraction cooperation, so that the car door is tight and stable when closed.

[0031] The door panels and door frames are made of heat-insulating materials to prevent heat exchange between the outside and the cold storage compartment through the door panels and door frames, which would affect the temperature inside the cold storage compartment.

[0032] It also includes a sensor for detecting whether the car door is fully closed. When the car door is not completely closed, the sensor sends an alarm signal to remind the operator. The specific sensor is referred to the existing technology and is not described in detail here.

[0033] The specific implementation process is as follows:

[0034] Install the door magnet body 1 into the receiving slot on the refrigerated truck door frame. Install the magnetic element 2 into the groove on the door, aligning the magnetic element 2 with the door magnet body 1. Ensure a good magnetic fit between the magnetic element 2 and the door magnet body 1, ensuring a tight and stable door when closed. Bolt the door magnet body 1 into the receiving slot using the fixing base 3 to prevent movement. Install the cover plate over the opening of the receiving slot. To open the door, ensure the force pulling the door open is greater than the attraction between the magnetic element 2 and the door magnet body 1.

[0035] This solution prevents water vapor, dust and other impurities from entering the receiving groove and causing damage to the door magnet body 1 by setting a seal; uses a cover plate to protect the door magnet body 1 to prevent dust and other impurities from entering the receiving groove and causing damage to the door magnet body 1; hides the door magnet body 1 and the magnetic attraction part 2 through the receiving groove and the groove, which not only ensures the magnetic attraction function of the refrigerated truck door, but also improves the overall aesthetics and thermal insulation performance of the door, and facilitates installation, maintenance and inspection work; the drainage hole is set to ensure that water can be discharged smoothly when there is accumulated water, and will not affect the overall structural strength and thermal insulation performance of the door frame due to being too large.
