[0002] With the explosive growth of the logistics industry and the maturity of intelligent vehicle technology, unmanned delivery has become an important way and development direction to solve branch logistics and "last mile" delivery problems.

[0003] For example, announcement number CN207809170U involves an intelligent logistics vehicle, including a front, an interior and storage cabinets. Taking into account the density of delivery volume in universities, the utility model defines the hardware system as 1+N multiple cabinets combined with one vehicle, with a large one-time delivery volume and low delivery cost; it absorbs the characteristics of intelligent perception and automatic obstacle avoidance on the market, with fast delivery speed and door-to-door delivery; the intelligent transport vehicle model no longer requires manual delivery, nor does it need to queue up to receive goods, and there is no need to worry about weather factors, and it is highly safe.

[0004] Since the size of the current logistics vehicle body is fixed, and the goods currently transported often include taller objects, the goods are often too high, so the goods can only be placed horizontally in the body, resulting in less remaining space inside, affecting the remaining loading space, resulting in overall limitations.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Reference Figure 1-4 , an intelligent logistics vehicle automatic height adjustment device comprises: a logistics vehicle body 1; a cargo compartment 2, which is arranged at the body of the logistics vehicle body 1, the cargo compartment 2 comprises a ceiling 21 and a compartment 23, the compartment 23 has a accommodating cavity 231 with an upper opening; a height adjustment component, which is arranged on the cargo compartment 2, the height adjustment component comprises a lifting member 24 and a PCBA mainboard 3 electrically connected to the lifting member 24, the lifting member 24 is at least two and symmetrically arranged at both ends of the middle part of the compartment 23, the bottom end of the ceiling 21 is connected to the telescopic end of the lifting member 24, and a ceiling 21 that can be lifted up and down is designed above the compartment 23. When the height of the goods is high and cannot be placed in the compartment 23, the ceiling 21 can be driven to move upward by the lifting member 24, which can increase the overall storage space, so as to facilitate the vertical placement of high-height objects and improve the overall applicability.

[0022] The lifting member 24 is an electric push rod, an electric telescopic rod or other components that can be driven to lift, which is not limited here.

[0023] Furthermore, the PCBA mainboard 3 is integrated with a voice controller 31 electrically connected thereto, and the voice controller 31 includes a microphone and an offline voice recognition chip connected thereto in communication. The PCBA mainboard 3 is also integrated with a memory, and the microphone can collect the user's voice signal, and the offline voice recognition chip can extract parameters representing the voice characteristics from the voice signal. During voice control, the vocabulary corresponding to the vocabulary data stored in the memory can be spoken (such as how many cm the rise / fall is, etc.), and after successful recognition, the corresponding control function can be executed according to a predetermined program, and when both hands are not free (such as when holding an object), the automatic adjustment operation of the height of the ceiling 21 can also be satisfied, and the operation is more convenient.

[0024] It should be noted that the circuit connection method of voice recognition control is a commonly used function in the prior art, and an additional noise reduction circuit may be provided, which will not be described in detail here.

[0025] Furthermore, it also includes a guide sleeve 28, which is arranged at the four corners of the upper end of the compartment 23. The bottom end of the ceiling 21 is correspondingly provided with a guide column 26 sliding in the guide sleeve 26. Through the cooperation of the wire sleeve 28 and the guide column 26, it can play an auxiliary guiding role for the up and down movement of the ceiling 21 to ensure the stability of the lifting and lowering of the ceiling 21.

[0026] Furthermore, a microwave ranging sensor 27 is embedded in the bottom end of one of the guide columns 26, and the microwave ranging sensor 27 is electrically connected to the PCBA main board 3. The microwave ranging sensor 27 can collect the current rising height in real time. When the desired height is reached, the microwave ranging sensor 27 transmits the data to the PCBA main board 3, and the PCBA main board 3 controls the lifting member 24 to stop working, thereby realizing automatic positioning operation.

[0027] Among them, the PCBA main board 3 is electrically connected to the main control terminal of the logistics vehicle body 1 itself.

[0028] Furthermore, a rainproof tarpaulin 25 connected to the bottom wall of the ceiling 21 is provided on the upper edge of the compartment 23. The rainproof tarpaulin 25 has folding patterns. The rainproof tarpaulin 25 can prevent rainwater from entering the compartment 23 when the ceiling 21 rises, thereby satisfying the lifting and lowering requirements while also having the functions of waterproofing and sealing. The folding patterns can also satisfy the folding operation of the rainproof tarpaulin 25 when it is retracted.

[0029] Furthermore, the outer periphery of the ceiling 21 is bent downward to form a protective flange 211, and a rain shielding surface is formed between the protective flange 211 and the ceiling 21. The size of the ceiling 21 is larger than that of the compartment 23. After being retracted, the protective flange 211 can provide additional rain shielding and protection.

[0030] Furthermore, a compartment door 22 is hinged on one side wall of the compartment body 23 by a hinge, and a sound inlet hole is opened on one side of the compartment door 22 on the compartment body 23, and the voice controller 31 is placed inside the sound inlet hole. The advantage of designing the sound inlet hole at this position is that since the position for taking and placing goods is on one side of the compartment door 22, the ceiling 21 lifting and lowering operation can be controlled at this position when taking and placing products, and the operation is more convenient.

[0031] In this case, an operating button for driving the lifting member 24 may also be additionally designed on one side of the compartment door 22 .

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
