[0022] The following is a detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-6 As shown, in some illustrative embodiments, a housing sealing structure of an automobile diagnostic terminal is provided, comprising: a display screen 1 , a first sealing member 2 , a second sealing member 3 , a ventilation member 4 , a heat dissipation mechanism 5 and a sealing component 6 .

[0024] The first sealing member 2 and the second sealing member 3 cooperate to form a sealed housing of the automobile diagnostic terminal of this embodiment.

[0025] The first sealing member 2 is used to carry the display screen 1. The existing automobile diagnostic terminal cannot clearly display the diagnosed problem when working, that is, it can only diagnose the vehicle and display the diagnosis status, but cannot directly reflect the diagnosis result. By setting the display screen 1, the automobile diagnostic terminal can immediately reflect the vehicle problem after diagnosis, so that the owner can know it.

[0026] The first sealing member 2 includes an upper shell 21. A sinking groove 22 is provided on the upper surface of the upper shell 21, and the groove wall of the sinking groove 22 is connected to the outer wall of the display screen 1, so that the upper shell 21 is fixedly covered around the display screen 1. The above structural design can enhance the strength of the sealing of the housing of the automobile diagnostic terminal, help the automobile diagnostic terminal to be used in bad weather, and increase its anti-fall performance.

[0027] An interface 24 is formed on the side wall of the upper shell 21 .

[0028] The second sealing member 3 is arranged at the bottom of the first sealing member 2. Specifically, the second sealing member 3 comprises: a lower shell 31. A groove 36 is provided on the upper surface of the lower shell 31. When the upper shell 21 is buckled on the top of the lower shell 31, the upper shell 21 covers the notch of the groove 36, so that the closed groove 36 forms a device cavity, in which electronic devices used in the terminal such as circuit boards can be placed to ensure sealing.

[0029] A button 34 and a switch 35 are disposed on the side wall of the lower housing 31 .

[0030] Among them, the first seal 2 and the second seal 3 are both provided with heat dissipation grooves 7, and the positions are corresponding, that is, when the upper shell 21 is buckled on the top of the lower shell 31, the heat dissipation grooves 7 on the first seal 2 and the second seal 3 are connected, and finally form an installation cavity, in which a heat dissipation mechanism 5 is arranged, and a ventilation member 4 is arranged outside the heat dissipation mechanism 5. The ventilation member 4 and the heat dissipation mechanism 5 cooperate to enhance the heat dissipation capacity of the automobile diagnostic terminal, and indirectly improve the diagnostic efficiency at the same time.

[0031] The ventilation member 4 comprises a ventilation plate 41. A ventilation slot 42 is formed on the ventilation plate 41, and two ends of the ventilation plate 41 are connected to the front and rear walls of the installation cavity.

[0032] The heat dissipation mechanism 5 includes: a positioning plate 51, a heat dissipation fan 54, a support shell 52 and a metal cover 53. The heat dissipation fan 54 is arranged on the positioning plate 51, and the metal cover 53 is arranged on the support shell 52. The support shell 52 is connected to the positioning plate 51 and is spaced a certain distance apart to ensure the heat dissipation effect. When the automobile diagnostic terminal diagnoses the vehicle, it needs to detect many functions. The detection intensity is relatively high and a large amount of heat will be generated. The position of the heat dissipation fan 54 is fixed by the positioning plate 51, so that the heat dissipation fan 54 can quickly discharge the heat derived from the metal cover 53 from the ventilation slot 42 opened on the ventilation plate 41, thereby improving the heat dissipation efficiency of the automobile diagnostic terminal and ensuring that it can complete the diagnosis of the vehicle with high efficiency.

[0033] The first seal 2 and the second seal 3 also include a sealing component 6. Specifically, a sealing component 6 is provided at each of the four corners of the upper shell 21, and a sealing component 6 is provided at each of the four corners of the lower shell 31. The sealing component 6 of the first seal 2 has the same structure as the sealing component 6 of the second seal 3, but the position is different.

[0034] The closing assembly 6 includes: a shell 231, and two limiting holes 232 are formed on the shell 231, and limiting pins 233 are arranged in the two limiting holes 232. The inner surface of the shell 231 in the closing assembly 6 arranged at the four corners of the upper shell 21 is connected to the outer surface of the upper shell 21; the inner surface of the shell 231 in the closing assembly 6 arranged at the four corners of the lower shell 31 is connected to the outer surface of the lower shell 31.

[0035] When assembling the sealed shell of the automobile diagnostic terminal, the upper shell 21 and the lower shell 31 are docked together, and the shell 231 of the sealing component 6 is respectively clamped on the four corners of the upper shell 21 and the lower shell 31, and then the sealing components 6 at the four corners of the upper shell 21 and the four corners of the lower shell 31 are connected by the limit pins 233, so that the upper shell 21 and the lower shell 31 can be tightly connected together under the action of the sealing component 6, thereby improving the sealing of the automobile diagnostic terminal shell. At the same time, the heat dissipation mechanism 5 cooperates with the ventilation member 4 to quickly discharge the heat generated inside the automobile diagnostic terminal during the diagnosis process, so that the automobile diagnostic terminal can work better.

[0036] After assembly, the connecting line can be inserted into the corresponding interface 24, and the other end can be connected to the car system. The switch key 35 can be pressed to turn on the car diagnostic terminal, and the control button 34 can be used to diagnose the vehicle. After the diagnosis is completed, the vehicle problem will be displayed on the display screen 1. At the same time, the first seal 2 cooperates with the second seal 3. No matter from which angle the car diagnostic terminal falls, it will not cause damage to the upper shell 21, the lower shell 31 and the display screen 1, thereby improving the service life of the car diagnostic terminal. The heat dissipation mechanism 5 cooperates with the ventilation member 4 to improve the heat dissipation effect of the car diagnostic terminal when detecting the vehicle, so that the diagnosis can be faster and the practicality of the sealing structure is improved.

[0037] The existing car diagnostic terminal has a poorly sealed shell, which is prone to failures due to rainwater infiltration during testing on rainy days. Insufficient sealing of the shell also easily causes the diagnostic terminal to affect internal components when it falls. The utility model forms a sealed shell of the car diagnostic terminal by cooperating with the first seal 2 and the second seal 3, and strengthens its sealing by cooperating with the sealing component 6, so that the car diagnostic terminal does not need to worry about the influence of rainy weather when in use, and the fall resistance of the car diagnostic terminal is improved, thereby improving the practicality of the sealing structure.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
