Technical Field
[0001] This utility model relates to the field of luggage technology, and in particular to a long, rectangular intelligent trolley case. Background Technology
[0002] Existing smart suitcases are mainly used to carry instruments, meters, or equipment. For suitcases carrying testing instruments, the electronic equipment inside (such as controllers and batteries) is prone to malfunction due to insufficient heat dissipation in high-temperature environments. Traditional suitcases lack active cooling designs, and internal temperatures can reach over 50°C during summer transport, posing a safety hazard. Therefore, there is an urgent need for a solution that can monitor ambient temperature in real time and automatically dissipate heat. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a long, rectangular intelligent trolley case that solves the problem of high internal temperature in previous cases.
[0004] To address the aforementioned technical problems, this utility model discloses a long, rectangular intelligent trolley case, comprising a case body, a trolley assembly fixedly installed on the back of the case body, and rollers fixedly installed on the bottom of the case body. The case body is fixedly equipped with a touchscreen for displaying temperature information and a temperature sensor for detecting the external ambient temperature. A partition is fixedly installed inside the case body to separate an independent air chamber and an equipment chamber. Cooling fans connected to the independent air chambers are fixedly installed on the left and right sides of the case body, respectively. A controller is fixedly installed within the independent air chamber, and the controller is electrically connected to both the temperature sensor and the cooling fans. A battery is fixedly installed within the equipment chamber, and the battery powers the touchscreen, temperature sensor, cooling fans, and controller.
[0005] The temperature sensor is embedded in the top of the enclosure, with the sensing end of the temperature sensor exposed on the top surface of the enclosure.
[0006] The touchscreen is fixedly installed on the top surface of the enclosure and is located to the side of the temperature sensor.
[0007] All cooling fans have the same airflow direction; the air inlet of the cooling fan on the left faces the outside of the cabinet, and the air outlet is connected to an independent air chamber; the air inlet of the cooling fan on the right faces the independent air chamber, and the air outlet faces the outside of the cabinet, so that the airflow direction is from left to right.
[0008] The controller integrates a temperature comparison unit and a PWM speed control module, and the cooling fan adjusts its speed according to the electrical signals from the temperature comparison unit and the PWM speed control module.
[0009] The battery is a removable lithium battery.
[0010] A power plug is also fixedly installed on the left side of the enclosure. The power plug is located above the cooling fan and is electrically connected to the controller.
[0011] The box body includes a box shell and a box cover hinged to the box shell, and a locking mechanism is provided between the box cover and the box shell.
[0012] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:
[0013] (1) The external ambient temperature is detected in real time by a temperature sensor, and the cooling fan is automatically started or stopped or its speed is adjusted by the controller to form a closed-loop temperature control system. When the electronic equipment (such as the controller and battery) inside the box is at risk of overheating due to the high external temperature, the system actively starts the cooling fan to introduce the low external air into the independent air cavity for heat exchange, which effectively prevents the electronic components from being damaged by high temperature, extends the equipment life, and solves the overheating problem in the past.
[0014] (2) The partition separates the independent air chamber inside the box. The airflow of the cooling fan circulates only in the air chamber, ensuring that the cooling airflow is completely physically isolated from the storage space of the box, and avoiding external hot air or dust from contaminating the items inside the box.
[0015] (3) The battery fixedly installed inside the equipment cavity provides independent power to the entire temperature control system, avoiding the failure of heat dissipation function due to external power interruption, and ensuring the continuous operation capability of the system under high temperature environment.
[0016] (4) The touch screen on the surface of the enclosure directly displays the ambient temperature information, enabling users to perceive external environmental risks in real time (such as high temperature warnings) and manage the equipment conveniently through touch operation, thereby improving the efficiency of human-computer interaction.
[0017] (5) The controller, heat dissipation duct and power supply module are integrated into the long strip box to realize complex functions in a limited space, maintain the portability of the box and meet the lightweight requirements of travel equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] This utility model discloses a specific embodiment of a long, narrow intelligent trolley case. Please see [link / reference]. Figure 1 The suitcase includes a case body 1, a retractable pull rod assembly 13, and universal casters 14. Specifically, the case body 1 can be made of high-strength PC material, the retractable pull rod assembly 13 is fixedly installed on the back of the case body 1, and a universal caster 14 is fixedly installed at each of the four corners of the bottom.
[0025] As an improvement, a touchscreen 41 and a temperature sensor 42 are embedded and fixedly mounted on the top surface of the enclosure 1. This mounting on the top surface prevents multiple enclosures 1 from being affected when placed side-by-side. The metal detection end of the temperature sensor 42 is exposed on the top surface of the enclosure 1 to directly contact the outside air. The touchscreen 41 is located approximately 5cm to the side of the sensor, used to display real-time ambient temperature values and warning information. This design allows users to intuitively perceive external environmental risks and improves the efficiency of travel decision-making.
[0026] In this embodiment, combined with Figure 2The interior of the housing 1 is divided into an independent air chamber 21 and an equipment chamber 22 by an ABS plastic partition 2. Specifically, the partition 2 can be fixed inside the housing 1 by welding, plugging, or threading. As a preferred solution, the edge of the partition 2 is ultrasonically welded to the inner wall of the housing 1 to ensure airtightness. This physical isolation structure completely blocks the contact between the heat dissipation airflow and the storage space, preventing items from being contaminated or damp.
[0027] Combination Figure 1 Each of the left and right side walls of the enclosure 1 is equipped with a 40mm diameter vortex-type cooling fan 3, and all the cooling fans 3 have the same airflow direction. The air inlet of the left fan faces outward and the air outlet connects to the independent air chamber 21; the air inlet of the right fan connects to the independent air chamber 21 and the air outlet faces outward. Together, they form a directional airflow channel from left to right. The directional airflow accelerates the air exchange efficiency within the air chamber, improving the heat dissipation performance by 40% compared to the unidirectional fan solution.
[0028] In this embodiment, a controller 23 is fixedly installed inside the independent air cavity 21, and its surface can be covered with an IP67 waterproof housing. The controller 23 integrates a temperature comparison unit and a PWM speed control module, and is connected to the temperature sensor 42 and the cooling fan 3 via cables. By setting specific parameters, the speed of the cooling fan 3 can be adjusted according to the external ambient temperature. For example, when the temperature sensor 42 detects a value <30℃, the fan is turned off; in the 30℃~35℃ range, a PWM signal is output to drive the fan to run at low speed (approximately 1500rpm); when the temperature is >35℃, it switches to full-speed mode (3000rpm). This dynamic temperature control mechanism significantly reduces the risk of overheating damage to electronic components.
[0029] In this embodiment, a removable battery is installed inside the device cavity 22. Preferably, the battery is a lithium battery pack (10000mAh capacity), which can be fixed using a snap-fit structure and supports USB-C wired charging and Qi wireless charging protocols. The battery continuously powers the touchscreen 41, sensors, fan, and controller 23, ensuring uninterrupted system operation in high-temperature environments and solving the problem of heat dissipation failure caused by external power interruption.
[0030] In addition, a power plug 15 is fixedly installed 10cm above the cooling fan 3 on the left side wall of the enclosure 1. Its metal contacts are electrically connected to the controller 23. The high-position design effectively avoids the risk of short circuit caused by water splashing on the ground.
[0031] The box body 1 in this embodiment includes a box shell 11 and a box cover 12 hinged to the box shell 11. It can be understood that the box body 1 is composed of the box shell 11 and the box cover 12 connected by a hinge. A mechanical locking mechanism is provided between the box shell 11 and the box cover 12. The specific locking mechanism can be a conventional latch lock.
[0032] In this embodiment, the suitcase uses a temperature sensor 42 to detect the external ambient temperature in real time and a controller 23 to automatically start and stop the cooling fan 3 or adjust its speed, forming a closed-loop temperature control system. When the electronic equipment inside the suitcase (such as the controller 23 and the battery) faces the risk of overheating due to high external temperatures, the system actively starts the cooling fan 3 to introduce low-temperature external air into the independent air chamber 21 for heat exchange, effectively preventing high-temperature damage to electronic components, extending the equipment's lifespan, and solving the previous overheating problem. A partition 2 separates the independent air chamber 21 inside the suitcase 1, ensuring that the airflow from the cooling fan 3 circulates only within the air chamber, completely physically isolating the cooling airflow from the storage space of the suitcase 1, and preventing external hot air or dust from contaminating the items inside the suitcase. The battery fixedly installed in the equipment cavity 22 provides independent power to the entire temperature control system, preventing the cooling function from failing due to external power interruption and ensuring the system's continuous operation in high-temperature environments. The touchscreen 41 on the surface of the suitcase 1 directly displays ambient temperature information, allowing users to perceive external environmental risks (such as high-temperature warnings) in real time and conveniently manage the equipment through touch operation, improving human-machine interaction efficiency. The controller 23, heat dissipation duct, and power supply module are integrated into the long rectangular box 1, realizing complex functions in a limited space, maintaining the portability of the box 1, and meeting the lightweight requirements of travel equipment.
[0033] Finally, it should be noted that the elongated intelligent trolley case disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
