Description

Technical Field

[0001] This utility model relates to the field of forklift accessories, specifically to a protective device for a cold storage forklift instrument and a cold storage forklift instrument. Background Technology

[0002] Forklift instruments are directly exposed to room temperature. When forklifts are used in cold storage, they need to frequently enter and exit the cold storage. At this time, the ambient temperature of the forklift's operation changes from -15℃ to normal room temperature (generally above 20℃). The drastic temperature change can easily cause the instrument's sealing structure to age, which in turn causes moisture to enter the instrument and cannot be discharged, ultimately leading to instrument damage.

[0003] One existing solution is to add a heat exchange module to the forklift instrument panel. This involves adding a heating element and a blower to the instrument panel, with the blower blowing air heated by the heating element into the instrument panel to maintain a certain temperature in the protected parts. While this solves the problem, the method is structurally complex, inconvenient to install, and costly. Utility Model Content

Detailed Implementation

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] In the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figure 1 and Figure 2 As shown, this embodiment provides a protective device for the instrument panel of a cold storage forklift, including a lower instrument glass cover 10, an instrument glass 20, and a transparent heating film 30; the lower instrument glass cover 10 is used to assemble the instrument assembly and is provided with a lower instrument window 11, such as... Figure 2 As shown, the area enclosed by the dashed line a is the region indicated by the lower instrument window 11; the assembly of the lower instrument glass cover 10 with the instrument assembly is prior art and will not be described in detail here. The bottom surface of the instrument glass 20 faces the lower instrument window 11 and is enclosed within the lower instrument window 11; the transparent heating film 30 is attached to the bottom surface of the instrument glass 20; as shown... Figure 1 As shown, the area of ​​the transparent heating film 30 is basically the same as that of the instrument glass 20.

[0021] Before assembling the instrument glass 20, the transparent heating film 30 is first attached to the bottom surface of the instrument glass 20. Then, the bottom surface of the instrument glass 20 is placed downwards and encapsulated inside the lower instrument window 11. In this way, the transparent heating film 30 is inside the forklift instrument and is well protected.

[0022] In use, the transparent heating diaphragm 30 is energized, causing it to heat up across the entire surface. The heat is evenly transferred to the instrument assembly, maintaining it within a specific temperature range and minimizing temperature differences during frequent entry and exit from cold storage. This effectively prevents aging and damage to the sealing structure caused by drastic temperature changes, ensuring the instrument's reliability and stability. Furthermore, the transparent heating diaphragm 30 does not obstruct the user's view and does not interfere with the instrument's use. It offers advantages such as simple structure, relatively easy installation, and relatively low cost.

[0023] Specifically, the transparent heating film 30 can be made of graphene transparent heating sheet, which has high heating efficiency and energy saving. For example, the graphene transparent heating sheet used in this embodiment only requires a 24V driving power supply with a power of less than 5W, which is inexpensive and can work in cold storage at temperatures ranging from -25℃ to 40℃, fully meeting the working environment of forklifts. Of course, in other embodiments, other films that meet the requirements (i.e., transparent materials and heating properties) can also be used.

[0024] The transparent heating film 30 has a connecting wire 31, which is sealed through the instrument glass lower cover 10 and extends to the outside of the instrument glass lower cover 10 for connecting to an external power source; if the connecting wire 31 extends outward and connects to a quick connector 32, a fast and safe electrical connection is formed with the external power source through the quick connector 32.

[0025] Furthermore, the transparent heating film 30 is also connected to a temperature control protection switch 33. Specifically, the temperature control protection switch 33 is connected in series in the electrical circuit of the transparent heating film 30, i.e., in series with the connecting wire 31. The temperature control protection switch 33 is fixed to an inner wall of the instrument glass lower cover 10 covered by the transparent heating film 30 to sense the heating temperature of the transparent heating film 30. When the heating temperature of the transparent heating film 30 exceeds the upper limit (e.g., a monitored temperature of 45°C), it disconnects, and the transparent heating film 30 is de-energized and stops working; when it falls below the upper limit (e.g., a monitored temperature of 38°C), it closes, and the transparent heating film 30 continues to be powered on for heating. This effectively prevents the transparent heating film 30 from overheating and being damaged. Of course, in other embodiments, the sensing object of the temperature control protection switch 33 is not limited to this, such as sensing the temperature of the external environment, the temperature of the instrument assembly, or the temperature of the instrument glass 20; the heating of the transparent heating film 30 can be specifically controlled according to the temperature of different reference objects sensed; for example, when sensing the temperature of the external environment, it closes when it is below 10°C and opens when it is above 10°C, etc.

[0026] Specifically, the lower cover 10 of the instrument glass also has an instrument display window 12 and an icon indicator area 13. The instrument display window 12 is used to install the display of the instrument assembly, and the icon indicator area 13 is used to arrange the function buttons of the instrument assembly. Both the instrument display window 12 and the icon indicator area 13 are within the range of the lower instrument window 11, that is, the instrument glass 20 and the transparent heating film 30 both cover the range of the instrument display window 12 and the icon indicator area 13, forming a large-area heating. Figure 2 As shown, the range shown in the instrument display window 12 is the area enclosed by the dashed line b, and the range shown in the icon indicator area 13 is the area enclosed by the dashed line c; both the instrument display window 12 and the icon indicator area 13 are within the area enclosed by the dashed line a.

[0027] A sealing ring 21 is fitted around the outer periphery of the instrument glass 20. The instrument glass 20 is sealed and encapsulated within the lower instrument window 11 by the cooperation of the sealing ring 21. That is, the sealing ring 21 seals and fills the gap between the outer side of the instrument glass 20 and the inner wall of the lower instrument window 11, thereby forming a sealed assembly.

[0028] Furthermore, it also includes an instrument glass upper cover 40, which is fixedly fitted onto the instrument glass lower cover 10. The instrument glass upper cover 40 and the instrument glass lower cover 10 together clamp and fix the instrument glass 20, that is, the instrument glass upper cover 40 presses against the upper surface of the instrument glass 20; the bottom surface of the instrument glass upper cover 40 is abutted by the instrument glass lower cover 10, thereby making the instrument glass 20 reliably installed; the instrument glass upper cover 40 and the instrument glass lower cover 10 are fixedly connected by bolts; when disassembly is required, the bolts are first removed, the instrument glass upper cover 40 is opened, and the instrument glass 20 and the transparent heating film 30 can be completely removed; the installation and disassembly operation is simple. The instrument glass upper cover 40 has an upper instrument window 41 corresponding to the lower instrument window 11, forming a viewing window.

[0029] Of course, in other embodiments, the instrument glass 20 and the lower instrument window 11 can also be sealed and fixed by other means, such as by directly applying glue to seal and fix them, that is, the instrument glass 20 is bonded to the lower instrument window 11 by the glued sealant layer, thereby achieving a sealed and fixed connection with the lower instrument window 11; in this way, the structure of the instrument glass cover 40 described above is not required, but compared with the above structure, it is not conducive to disassembly and assembly operations.

[0030] Furthermore, this embodiment also provides a cold storage forklift instrument, which includes at least the protection device for the cold storage forklift instrument described above.

[0031] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
