Description

Technical Field

[0001] This utility model belongs to the field of navigation device technology, specifically relating to a navigation device with voice recognition function. Background Technology

[0002] In the development of intelligent vehicles, the in-vehicle infotainment system (V2X) is a core component for vehicle information interaction and function control, and its operational stability is crucial. The V2X is an intelligent device that integrates voice interaction and positioning / navigation technologies. It primarily uses voice commands to achieve functions such as route planning, navigation guidance, and information retrieval, aiming to improve the convenience and safety of user operation.

[0003] Inside vehicles, navigation devices with voice recognition capabilities are often installed near the windshield or air vents. Most current navigation devices are embedded in the car's infotainment system, and when these systems connect to the vehicle, a gap is unavoidable at the connection point. This seemingly minor gap can actually pose a hidden danger. During driving, due to vehicle bumps and passenger movement, passengers may inadvertently spill water from their cups onto the infotainment system. If this happens, the liquid, due to gravity, will seep through the gap to the back of the system. The back of the infotainment system is covered with complex electronic components and wiring; water intrusion can easily cause short circuits and component corrosion. Utility Model Content

[0004] The purpose of this invention is to provide a navigation device with voice recognition functionality, aiming to solve the problem that during driving, due to factors such as vehicle bumps and passenger movement, passengers may inadvertently spill water from their cups onto the vehicle's infotainment system. In such cases, the liquid, due to gravity, will seep through gaps to the back of the infotainment system. The back of the system is covered with sophisticated electronic components and circuits; water intrusion can easily cause short circuits and component corrosion.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a navigation device with voice recognition function, including a vehicle-mounted unit, wherein a screen is fitted onto the surface of the vehicle-mounted unit, and a rectangular sealing groove is provided on the back of the vehicle-mounted unit, wherein a sealing strip is interference-fitted into the interior of the sealing groove;

[0006] A set of protruding posts are evenly installed on the inner walls of both sides of the sealing groove. A protruding block is integrally installed on the other end of each protruding post. The protruding posts and protruding blocks are made of hard rubber and are connected to the outer walls of both sides of the sealing strip.

[0007] In order to ensure that the moisture that seeps into the back of the vehicle from the gap between the surface of the vehicle and the upper connection end of the vehicle mounting can be absorbed by the absorbent cotton in time, as a navigation device with voice recognition function of this utility model, preferably, two mounting grooves are opened on the side surface above the sealing strip, and an absorbent cotton is glued to the inside of each mounting groove, and the surface of the absorbent cotton is at the same level as the surface of the opening end of the mounting groove.

[0008] Each of the mounting slots has a set of through holes at equal intervals at the bottom. The through holes are funnel-shaped with the larger end facing upwards.

[0009] In order to allow the moisture entering the collection tank to be absorbed by the drying beads, as a navigation device with voice recognition function of this utility model, preferably, the small opening below the through hole is connected to the top of the collection tank, and the inside of the collection tank is filled with drying beads.

[0010] The gathering groove is located inside the side above the sealing strip.

[0011] In order to ensure that the sealing strip can be fixedly installed in the sealing groove by the protrusions and protrusions, thereby preventing the sealing strip from being misaligned during the docking of the vehicle and the car installation parts, as a navigation device with voice recognition function of this utility model, preferably, a set of slots is opened on the upper and lower sides of the sealing strip, and each set of slots is interference-fitted with a set of protrusions and protrusions.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When using, insert the sealing strip into the sealing groove. After installation, press the sealing strip firmly into the sealing groove so that the grooves on the upper and lower sides of the sealing strip align with the corresponding protrusions and blocks. This allows the sealing strip to be installed on the back of the vehicle's infotainment system through the sealing groove. After installation, the side of the sealing strip with the absorbent cotton should face upwards.

[0014] Next, connect the wiring port on the back of the head unit to the wiring harness of the car mounting section. After connection, insert the head unit into the car mounting section. The sealing strip on the back of the head unit will be located inside the car mounting section, and will be positioned between the head unit and the car mounting section. At this time, the edge strip above the horizontal center line of the sealing strip will be located below the upper gap. When in use, if water accidentally splashes into the upper gap, some water will enter the back of the head unit.

[0015] Water that gets into the back of the infotainment system will fall onto the absorbent cotton, be absorbed by the cotton, and slowly fall into the collection tank through the bottom hole. Finally, it will be absorbed by the desiccant in the collection tank. This prevents water from accidentally falling into the back of the infotainment system and damaging the electronic components there. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 The present invention provides the following technical solution: a navigation device with voice recognition function, including a vehicle unit 1, a screen 2 is fitted on the surface of the vehicle unit 1, a rectangular sealing groove 4 is provided on the back of the vehicle unit 1, and a sealing strip 3 is interference-fitted inside the sealing groove 4;

[0027] The vehicle's infotainment system 1 runs on Linux and can download common car navigation software. After installing the navigation software, voice control commands can be enabled in the software's settings. This allows the system to recognize voice commands and complete the corresponding voice navigation instructions.

[0028] A set of protruding posts 5 are evenly installed on the inner walls of the two sides of the sealing groove 4. A protruding block 6 is integrally installed on the other end of each protruding post 5. The protruding posts 5 and the protruding blocks 6 are made of hard rubber and are connected to the outer walls of the two sides of the sealing strip 3.

[0029] Preferably, two mounting grooves 31 are provided on the side surface above the sealing strip 3, and a water-absorbing cotton 36 is glued to the inside of each mounting groove 31. The surface of the water-absorbing cotton 36 is at the same level as the surface of the opening end of the mounting groove 31.

[0030] Each mounting groove 31 has a set of through holes 32 at equal intervals at its bottom. The through holes 32 are trumpet-shaped, with the larger end of the through holes 32 facing upwards.

[0031] Preferably, the small opening below the through hole 32 is connected to the top of the collection groove 33, and the inside of the collection groove 33 is filled with drying beads 35;

[0032] The gathering groove 33 is formed inside the side above the sealing strip 3.

[0033] Preferably, a set of slots 34 are provided on the upper and lower sides of the sealing strip 3, and each set of slots 34 is interference-fitted with a set of protrusions 5 and protrusions 6.

[0034] In practical use, first, pick up the sealing strip 3 and accurately insert it into the sealing groove 4 on the back of the vehicle's infotainment system 1 to complete the initial fixation. After installation, apply force evenly along the length of the sealing strip 3 to further press it into the sealing groove 4. During this process, pay special attention to the slots 34 on the upper and lower side strips of the sealing strip 3 to ensure that they precisely align with the corresponding protrusions 5 and 6 in the sealing groove 4. This operation must ensure that each slot 34 fully engages with the protrusions 5 and 6 to form a stable connection, preventing the sealing strip 3 from falling off during subsequent use. During installation, ensure that the side of the sealing strip 3 with the absorbent cotton 36 faces upwards; this orientation plays a crucial role in the subsequent waterproofing function.

[0035] After installing the sealing strip 3, connect the wiring ports on the back of the vehicle-mounted unit 1 to the wiring harness of the vehicle mounting part. During connection, refer to the port markings and wiring harness colors to ensure each interface is connected accurately to avoid circuit malfunctions due to incorrect connections. After connection, gently insert the back of the vehicle-mounted unit 1 into the corresponding mounting part or bracket on the vehicle. Keep the vehicle-mounted unit 1 stable during installation to prevent loosening of the wiring harness or displacement of the sealing strip 3 due to shaking. After installation, the sealing strip 3 on the back of the vehicle-mounted unit 1 will fit tightly against the inside of the vehicle mounting end, filling the gap between the vehicle-mounted unit 1 and the vehicle mounting part. At this point, the edge strip above the horizontal center line of the sealing strip 3 is precisely below the upper gap, forming the first waterproof barrier.

[0036] During daily vehicle use, if passengers accidentally splash water onto the gap between the vehicle infotainment system 1 and the vehicle's mounting area, some water may seep through the gap to the back of the system. However, due to the installation of the sealing strip 3, with the absorbent cotton 36 facing upwards, when water comes into contact with the absorbent cotton 36, it is quickly absorbed into the cotton 36 due to capillary action and the cotton 36's special fiber structure. As the absorbent cotton 36 absorbs more water, excess water will slowly fall into the collection groove 33 below through the through-hole 32 at the bottom of the absorbent cotton 36 under the influence of gravity. The collection groove 33 is filled with desiccant beads 35, which are typically made of highly absorbent materials such as silica gel or superabsorbent polymers. These beads have strong water absorption capabilities, quickly absorbing the water in the collection groove 33 and locking it in. Through this series of waterproof designs and workflows, the corrosion of the electronic components on the back of the vehicle infotainment system 1 by accidental water stains is effectively prevented, ensuring that the vehicle infotainment system 1 can still operate stably and reliably in humid environments, greatly extending the service life of the vehicle infotainment system 1 and ensuring the safety of the vehicle's electronic system.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
