Detailed Implementation

[0026] To enable those skilled in the art to better understand the embodiments of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] The display mounting brackets of cold chain displays in related technologies have specially designed wiring harness mounting positions, such as wiring harness mounting cavities, to accommodate the installation and arrangement of the display's wiring harnesses, or wiring through holes to accommodate the arrangement and installation of the display's wiring harnesses. However, the addition of wiring harness mounting cavities or wiring through holes to the display mounting bracket reduces the material cross-section of the display mounting bracket, lowers the load-bearing capacity of the display mounting bracket, and results in insufficient strength of the display mounting bracket.

[0029] See Figure 1This utility model provides a cold chain display 100, which can be applied to low-temperature equipment such as freezers and cold storage to meet the display requirements of low-temperature equipment in low-temperature environments.

[0030] See Figures 1 to 4 In some embodiments, the cold chain display 100 includes a display screen 11, a display mounting bracket 12, at least one connecting protrusion 122, and a housing 13. The display screen 11 is mounted on the display mounting bracket 12. The display mounting bracket 12 has a first outer side wall 121, and the connecting protrusion 122 protrudes from the first outer side wall 121 and connects to the housing 13, so that the housing 13 covers the display mounting bracket 12, and the first outer side wall 121 and the inner wall 131 of the housing 13 form a cable passage 1211. The display screen 11 can be liquid crystal glass, for example, a wide-temperature glass, which can be configured according to actual conditions.

[0031] Thus, the cable routing channel 1211 can accommodate the wiring harness arrangement of the display screen 11, facilitating the arrangement of the wiring harness of the display screen 11. This helps to reduce the situation where the wiring harness of the display screen 11 is scattered and tangled with the wiring harnesses of other devices in the display mounting bracket 12. It also helps to make reasonable use of the space between the housing 13 and the display mounting bracket 12. The display mounting bracket 12 does not need to have a separate wiring harness mounting position to install the wiring harness, which helps to ensure that the display mounting bracket 12 has sufficient strength and reliability. It also helps to simplify the structure of the display mounting bracket 12 and facilitate manufacturing.

[0032] In addition, the connecting protrusion 122 can position the connection between the housing 13 and the display mounting bracket 12, which helps to improve the accuracy of the connection position between the housing 13 and the display mounting bracket 12 and improves the connection efficiency between the housing 13 and the display mounting bracket 12.

[0033] The connecting protrusion 122 can be cylindrical. The cylindrical connecting protrusion 122 can reduce stress concentration points and reduce the risk of structural fatigue and damage caused by stress concentration.

[0034] The connection between the connecting protrusion 122 and the outer shell 13 can be achieved through snap-fitting, fastener connection, or other methods, depending on the specific circumstances. The following explanation uses the fastener connection method between the connecting protrusion 122 and the outer shell 13 as an example.

[0035] See Figure 2 , Figure 4 and Figure 5In some embodiments, the connecting protrusion 122 abuts against the inner wall 131, the outer shell 13 is provided with a first connecting hole 132, the connecting protrusion 122 is provided with a second connecting hole 1221, and the cold chain display 100 includes a first fastener 14, which passes through the first connecting hole 132 and is connected to the second connecting hole 1221.

[0036] Thus, the first fastener 14 can secure the display mounting bracket 12 and the housing 13, helping to reduce the possibility of the housing 13 becoming loose from the display mounting bracket 12. The cable passage 1211 between the first outer wall 121 and the inner wall 131 of the housing 13 can accommodate the wiring harness arrangement of the display screen 11, while the connecting protrusion 122 is in close contact with the inner wall 131 to provide additional support points for the housing 13, which helps to enhance the connection strength between the housing 13 and the display mounting bracket 12, improve the stability of the overall structure, and the connecting protrusion 122 can serve as a stress dispersion point, helping to reduce stress concentration at the connection of the first fastener 14, and helping to reduce the risk of damage to the connecting protrusion 122 due to local overload.

[0037] The first fastener 14 can be a screw, bolt, or other structure, and can be set according to the actual situation, as long as the first fastener 14 can fasten the display mounting bracket 12 and the outer shell 13.

[0038] See Figure 5 and Figure 6 In some embodiments, the display mounting bracket 12 further includes an elastic portion 123, which is disposed on the edge of the first outer side wall 121, and the connecting protrusion 122 is disposed relative to the display screen 11 near the elastic portion 123.

[0039] Due to the height limitation of the first outer wall 121, the connecting protrusion 122 is located close to the edge of the first outer wall 121. However, this solution requires drilling a second connecting hole 1221 on the connecting protrusion 122. At the edge of the first outer wall 121, due to the change in geometry, the stress distribution is often uneven. Drilling a second connecting hole 1221 on the connecting protrusion 122 will cause stress concentration around the second connecting hole 1221, which poses a risk of deformation of the structure around the second connecting hole 1221.

[0040] This solution provides an elastic portion 123 along the edge of the first outer side wall 121 and close to the connecting protrusion 122. This allows the elastic portion 123 to absorb and disperse the stress concentration generated during the drilling process of the connecting protrusion 122, reducing the local stress in the material around the second connecting hole 1221. This reduces the risk of deformation of the structure around the second connecting hole 1221. Furthermore, the elastic portion 123 has a certain degree of elasticity, which can absorb the vibration and impact generated during the drilling process, reducing the impact of external forces on the edge of the display mounting bracket 12 and reducing the risk of deformation of the structure around the second connecting hole 1221.

[0041] In some embodiments, the cold chain display 100 includes a plurality of connecting protrusions 122, which are all protruding from the first outer side wall 121 and are equidistantly distributed along the length direction X of the cold chain display 100.

[0042] This helps to increase the contact area between the display mounting bracket 12 and the housing 13, improves the stability of the connection between the display mounting bracket 12 and the housing 13, enhances the structural strength and deformation resistance of the display mounting bracket 12 and the housing 13, ensures that the display mounting bracket 12 and the housing 13 are subjected to uniform force during installation, reduces local stress concentration, and thus helps to improve the overall structural stability and durability. It also helps to disperse the impact force when the housing 13 and the display mounting bracket 12 are subjected to impact, reducing damage to the display screen 11 and other components.

[0043] "Multiple" refers to two or more. For example, the display mounting bracket 12 may include two, three, four, five, six or other numbers of connecting protrusions 122, which can be set according to the actual situation.

[0044] See Figure 2 Figure 5 ,and Figure 7 In some embodiments, the display mounting bracket 12 is further provided with a second outer side wall 124, which is distributed along the width direction Y of the cold chain display 100 with the first outer side wall 121, and the second outer side wall 124 abuts against the inner wall 131.

[0045] In this way, the second outer wall 124 can be in close contact with the inner wall 131, which helps to increase the contact area between the display mounting bracket 12 and the housing 13, helps to improve the stability of the connection between the display mounting bracket 12 and the housing 13, helps to improve the structural strength and deformation resistance of the display mounting bracket 12 and the housing 13, and also helps to improve the sealing between the display mounting bracket 12 and the housing 13, preventing external substances such as liquids and water vapor from entering the display mounting bracket 12, and reducing the possibility of water damage to the devices inside the display mounting bracket 12 and the housing 13.

[0046] The cold chain display 100 also includes fasteners that pass through the inner wall 131 and are connected to the second outer wall 124, thereby securing the display mounting bracket 12 and the housing 13 from the other side.

[0047] In some embodiments, the cold chain display 100 further includes a circuit mounting bracket 15 and a circuit board 16, the circuit board 16 being mounted on the circuit mounting bracket 15, the circuit mounting bracket 15 and the display mounting bracket 12 being distributed along the height direction Z of the cold chain display 100, and the display mounting bracket 12 separating the circuit board 16 and the display screen 11.

[0048] This helps reduce mutual heat interference and transfer between the circuit board 16 and the display screen 11, improves the heat dissipation efficiency of the circuit board 16 and the display screen 11, reduces the performance degradation caused by overheating of the circuit board 16 and the display screen 11, reduces electromagnetic interference between the circuit board 16 and the display screen 11, improves the electromagnetic compatibility of the cold chain display 100, reduces unnecessary signal interference, and improves the stability of the display and circuit of the cold chain display 100.

[0049] Furthermore, by separating the circuit board 16 and the display screen 11, the internal space of the cold chain display 100 can be planned more rationally, improving space utilization and facilitating wiring and component installation.

[0050] In some embodiments, the circuit mounting bracket 15 is provided with a clearance notch 151 and a mounting cavity 152, the circuit board 16 is mounted in the mounting cavity 152, and the clearance notch 151 connects the wiring channel 1211 and the mounting cavity 152.

[0051] Thus, the clearance notch 151 can avoid the wiring harness of the display screen 11. The clearance notch 151 will not hinder the installation and arrangement of the wiring harness of the display screen 11. The clearance notch 151 helps to facilitate the arrangement of the wiring harness of the display screen 11, so that the wiring harness of the display screen 11 can enter the mounting cavity 152 through the wire passage 1211 and the clearance notch 151 and connect to the circuit board 16, thereby ensuring the normal display of the display screen 11.

[0052] In some implementations, the clearance notch 151 is misaligned with the connecting protrusion 122.

[0053] In this way, the connecting protrusion 122 will not obstruct the wire harness of the display screen 11 from passing through the clearance notch 151. By reasonably arranging the positions of the clearance notch 151 and the connecting protrusion 122, it is helpful to facilitate the arrangement of the wire harness of the display screen 11 and reduce bending and tangling during the installation of the wire harness of the display screen 11, so as to ensure the normal connection between the wire harness of the display screen 11 and the circuit board 16.

[0054] In some embodiments, the cold chain display 100 includes a second fastener 17, the housing 13 is provided with a third connection hole 133, the circuit mounting bracket 15 is provided with a fourth connection hole 154, the second fastener 17 passes through the third connection hole 133 and is connected to the fourth connection hole 154, and the second connection hole 1221 and the fourth connection hole 154 are arranged side by side along the height direction Z.

[0055] Thus, by rationally arranging the positions of the second connecting hole 1221 and the fourth connecting hole 154, it is helpful to quickly locate the connection positions of the first fastener 14 and the second fastener 17, and facilitate the quick connection of the housing 13 with the display mounting bracket 12 and the circuit mounting bracket 15, thereby improving the connection efficiency of the housing 13 with the display mounting bracket 12 and the circuit mounting bracket 15, and also helping to improve the overall aesthetics of the cold chain display 100.

[0056] The second fastener 17 can be a screw, bolt, or other structure, and can be set according to the actual situation, as long as the first and second fasteners can fasten the circuit mounting bracket 15 and the outer shell 13.

[0057] The outer wall of the circuit mounting bracket 15 can be in close contact with the inner wall 131, which helps to increase the contact area between the circuit mounting bracket 15 and the housing 13, improves the stability of the connection between the circuit mounting bracket 15 and the housing 13, enhances the structural strength and deformation resistance of the circuit mounting bracket 15 and the housing 13, and also helps to improve the sealing between the circuit mounting bracket 15 and the housing 13, preventing external substances such as liquids and water vapor from entering the circuit mounting bracket 15 and reducing the possibility of water damage to the components inside the circuit mounting bracket 15 and the housing 13.

[0058] In some embodiments, the cold chain display 100 further includes a protective element 18, which is fully attached to the display screen 11. The protective element 18 can be tempered glass, for example, anti-glare tempered glass, and can be configured according to actual conditions.

[0059] In this way, the protective component 18 helps to protect the display screen 11, which helps to reduce the risk of screen breakage due to accidental drops, impacts, etc. It also helps to improve the sealing between the display screen 11 and the protective component 18, which helps to reduce the adhesion of external substances such as liquids and water vapor to the display screen 11 and affect the display, and helps to ensure the clear display of the cold chain display 100.

[0060] The protective component 18 and the display screen 11 can be fully bonded together using adhesive. For example, the adhesive can completely cover the surface of the protective component 18 facing the display screen 11, and the protective component 18 can be fully bonded to the display screen 11 by the adhesive. The specific settings can be configured according to the actual situation.

[0061] In some embodiments, the protective element 18 is one of polarized glass, anti-reflective glass, or high-transmittance glass.

[0062] This helps improve the visibility of the display screen 11, improves the clarity of the image, ensures the display screen 11 can be used in low-temperature environments, and makes it convenient for users to monitor parameters such as temperature and humidity through the cold chain display screen 100.

[0063] For example, the protective element 18 can be polarized glass, which helps reduce glare from sunlight or other light sources, improves visibility in bright light environments, enhances the contrast of the display screen 11, makes the image clearer, ensures visibility under different lighting conditions, and also helps reduce eye fatigue and protect the user's eyesight.

[0064] For example, the protective component 18 can be anti-reflective glass. Anti-reflective glass helps reduce light reflection, improves the visibility of the display screen 11 under various lighting conditions, and reduces reflection, which helps the image to be clearer, ensures visibility under different lighting conditions, and also helps reduce visual interference caused by reflected light, providing users with a more comfortable visual experience.

[0065] For example, the protective component 18 can be high-transmittance glass, which allows more light to pass through, helping to improve the brightness and clarity of the display screen 11, and also helping to reduce the backlight requirement, thereby reducing the energy consumption of the cold chain display 100.

[0066] In summary, the cold chain display 100 provided by this embodiment of the utility model has a display screen 11 mounted on a display mounting bracket 12. The display mounting bracket 12 has a first outer side wall 121, and a connecting protrusion 122 protrudes from the first outer side wall 121. The connecting protrusion 122 is connected to the outer shell 13, so that the outer shell 13 covers the display mounting bracket 12, and the first outer side wall 121 and the inner wall 131 of the outer shell 13 form a wire passage channel 1211. In this way, the wire passage channel 1211 can meet the arrangement of the wire harness of the display screen 11, which is convenient for the arrangement of the wire harness of the display screen 11. It helps to reduce the situation where the wire harness of the display screen 11 is scattered in the display mounting bracket 12 and entangled with the wire harness of other devices. It also helps to make reasonable use of the space between the outer shell 13 and the display mounting bracket 12. The display mounting bracket 12 does not need to have a separate wire harness mounting position to install the wire harness, which helps to ensure that the display mounting bracket 12 has sufficient strength, helps to ensure the reliability of the display mounting bracket 12, and also helps to simplify the structure of the display mounting bracket 12 and facilitate manufacturing.
