[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.
[0027] Example:
[0028] See also Figure 1-6A vehicle-mounted hard disk heating device comprises a mounting frame plate 1, a cover plate 2 is threadedly connected to the upper end of the mounting frame plate 1, two pairs of mounting pillars 4 are fixedly connected to the lower end of the cover plate 2, and a vehicle-mounted hard disk body 3 is threadedly connected between the lower ends of the two pairs of mounting pillars 4, a temperature sensor 5 is installed on the upper end of the vehicle-mounted hard disk body 3, a PTC electric heating film 6 is installed on the inner bottom end of the mounting frame plate 1, a plurality of heat conducting sheets 7 are fixedly connected to the inner bottom end of the mounting frame plate 1, and the plurality of heat conducting sheets 7 are respectively in contact with the PTC electric heating film 6 and the vehicle-mounted hard disk body 3, a conducting groove 8 is opened at both front and rear ends of the mounting frame plate 1, and a breathable partition net 9 is fixedly connected to the inner wall of the conducting groove 8 near the outer side, a shielding telescopic curtain 10 is slidably connected to the inner wall of the conducting groove 8 near the inner side, and a telescopic adjustment mechanism 11 is installed between the shielding telescopic curtain 10 and the mounting frame plate 1 and the temperature sensor 5.
[0029] During the use of this solution, the outdoor temperature in Harbin is often below minus 20 degrees Celsius in winter. When the bus is parked outdoors at night, the temperature inside the bus is extremely low. In order to prevent the low temperature from affecting the normal storage, reading and writing of the vehicle hard disk body 3, the temperature sensor 5 will feedback to the PTC electric heating film 6 when it detects that the ambient temperature around the vehicle hard disk body 3 is low, so that it is heated, and the heat is quickly transferred to the vehicle hard disk body 3 through multiple heat conducting sheets 7, so that the ambient temperature on the vehicle hard disk body 3 rises rapidly. At the same time, the micro electric slide rail 1102 in the telescopic adjustment mechanism 11 also drives the driving slider 1103 to slide under the low temperature feedback of the temperature sensor 5, pushing the shielding telescopic curtain 1 0 is extended to seal the conduction groove 8 to reduce heat loss and ensure its working temperature. When the temperature is heated to the critical value of the temperature heating, the temperature sensor 5 feeds back to the PTC electric heating film 6 to stop heating. Then the vehicle-mounted hard disk body 3 is powered on to perform normal data storage and reading and writing, so that when an emergency occurs later, the vehicle-mounted video data can be effectively retrieved for accident verification to reduce losses. In this solution, the temperature sensor 5, the PTC electric heating film 6 and the micro electric slide rail 1102 are all mature products known in the prior art, which are widely used in daily life and belong to common knowledge in the field. Therefore, they are not elaborated in this solution.
[0030] See also Figure 3 The temperature sensor 5 is provided with a temperature heating critical value, and the degree of the temperature heating critical value is 5°C.
[0031] During use of this solution, the normal suitable working temperature of the vehicle-mounted hard disk body 3 is 5° C. Setting the temperature at 5° C. can ensure the normal operation of the vehicle-mounted hard disk body 3 and avoid the influence of excessively high or low temperature on it.
[0032] See also Figure 4-6A pair of telescopic adjustment mechanisms 11 each include a connecting piece 1101 fixedly connected to the outer end of the shielding telescopic curtain 10, and a pair of front-to-rear miniature electric slide rails 1102 are installed on the inner wall of the mounting frame 1. A driving slider 1103 is sleeved on the miniature electric slide rail 1102, and the driving slider 1103 is slidably connected to the miniature electric slide rail 1102. The lower end of the driving slider 1103 is fixedly connected to the upper end of the connecting piece 1101, and the miniature electric slide rail 1102 is electrically connected to the temperature sensor 5.
[0033] During use of the present solution, the micro electric slide rail 1102 drives the driving slider 1103 to slide, so that it drives the connecting piece 1101 to move in the left and right directions, causing the shielding telescopic curtain 10 to extend or contract, thereby sealing the conducting groove 8 under low-temperature heating temperature to reduce heat loss, and opening the conducting groove 8 under high-temperature environment to allow heat to quickly dissipate outward through the breathable partition net 9, thereby enhancing the heat dissipation effect and ensuring the normal operation of the vehicle-mounted hard disk body 3.
[0034] See also Figure 4 The outer ends of the plurality of heat conducting plates 7 are all L-shaped, and the surfaces of the plurality of heat conducting plates 7 are all provided with a ceramic heat conducting powder layer.
[0035] During use, the present solution can be conveniently arranged in an L-shaped manner to contact the PTC electric heating film 6 and the vehicle-mounted hard disk body 3 respectively, so as to achieve a good heat conduction effect with the assistance of the ceramic heat-conducting powder layer.
[0036] See also Figure 6 The upper and lower ends of the shielding telescopic curtain 10 are fixedly connected with sliders 1001, and the inner wall of the conducting groove 8 is cut with a pair of upper and lower symmetrical sliding grooves 1002, and the pair of sliders 1001 are respectively located in the pair of sliding grooves 1002 and slidably connected thereto.
[0037] During use, the present invention provides the slider 1001 and the slide groove 1002 to achieve sliding assistance when the shielding telescopic curtain 10 is telescopically moved in the left and right directions, so that the curtain maintains linear motion, is less likely to deviate, and improves motion stability.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
