Description

Technical Field

[0001] This utility model relates to the field of navigation device technology, and in particular to a front cover plate for a navigation device that is waterproof and easy to dissipate heat. Background Technology

[0002] As a core interactive device for drivers, the stability of a navigation system directly affects driving safety. The exposed screen is prone to blurring due to scratches, increasing the risk of driver distraction. Therefore, a front cover plate needs to be installed on the surface of the navigation system to protect its outer layer.

[0003] In existing technologies, the front cover is usually installed on the front surface of the navigator in a flip-up manner. By flipping it upwards, it can be opened to allow the user to access and adjust the navigator. After adjustment, the front cover is flipped downwards to cover the front of the navigator and protect the front of the navigator.

[0004] However, there are still certain limitations in actual use. Because the existing navigator front cover adopts a single flip structure, that is, the front cover is flipped up to open and flipped down to close via a hinge or pivot, there is a gap between the front cover and the navigator. As a result, the fit between the front cover and the navigator is poor. When used in humid weather such as rain, water can easily seep into the gap between the front cover and the navigator, which can cause problems such as short circuits and touch failure. Moreover, traditional covers cannot provide shade in summer, and the navigator is easily affected by sunlight when operating it, making it inconvenient to operate. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a waterproof and heat-dissipating front cover for a navigator. This solves the problem of gaps between the front cover and the navigator, resulting in poor fit and allowing water to easily seep in during rainy or humid weather. This can cause short circuits, touchscreen malfunctions, and difficulties in operating the navigator. The new design achieves a tight fit and fixation of the front cover to the navigator's surface, reducing water infiltration, significantly improving waterproofing, enabling the navigator to function normally in humid environments, and facilitating user access and control of the navigator.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a front cover plate for a navigator with waterproof function and easy heat dissipation, including a front cover plate body for covering the front end of the navigator body, a sealing gasket for preventing water stains from seeping in between the front cover plate body and the navigator body, a positioning component on the front cover plate body, the positioning component including a fixing block for fixing and installing at the rear end of the front cover plate body, and a connecting block for fixing and installing at the groove of the outer wall of the navigator body, the outer wall of the connecting block has an inlet, and the outer end of the fixing block is inserted into the inlet to fasten the front cover plate body to the front outer wall of the navigator body;

[0007] The inner wall of the connecting block is provided with a slot communicating with the inlet. The fixed block has a drive block that is adapted to the slot sliding inside. The inner cavity of the fixed block is fixedly installed with a compression spring that drives the drive block to be inserted into the slot.

[0008] The front cover plate is provided with a transparent plate to facilitate viewing the content displayed on the main body of the navigator, and the outer wall of the transparent plate is provided with a light-blocking cloth.

[0009] Preferably, the drive block is slidably connected inside the drive block, and the drive block is fixedly connected to the compression spring.

[0010] Preferably, a connecting box is fixedly installed on the top of the front cover plate body, and a movable block that slides horizontally is provided inside the connecting box. The outer side of the movable block is rotatably connected to a linkage block that is fixedly installed with the front cover plate body through a pin.

[0011] Preferably, the outer wall of the front cover plate body is rotatably provided with a winding roller for winding up the cover cloth, and both ends of the winding roller are provided with torsion springs for winding and resetting.

[0012] Preferably, the end of the covering cloth is fixedly connected to a collar, and the collar is hooked onto a hanging block fixedly installed on the front cover body.

[0013] Preferably, limiting plates are fixedly installed on the outer walls of both sides of the drive block, and the two sets of limiting plates are limited and fitted against the inner side wall of the fixed block.

[0014] Preferably, the contact surface between the drive block and the connecting block is sloped, and the drive block is internally connected to a drive wheel.

[0015] Preferably, a heat sink for conducting heat is fixedly inserted through the main body of the front cover plate.

[0016] By employing the above technical solution, this utility model provides a front cover plate for a navigation device that is waterproof and easy to dissipate heat, and has at least the following beneficial effects:

[0017] 1. This utility model features a front cover plate that first flips downwards and then moves laterally towards the surface of the navigator body. A fixing block is inserted into the inlet, and a locking block is engaged in the slot, ensuring the front cover plate is tightly fitted and fixed to the surface of the navigator body. A sealing gasket is used to seal the connection, reducing water infiltration and significantly improving waterproofing. This allows the navigator to be viewed and used normally in humid environments. Furthermore, a covering cloth can be used to shield the transparent panel, which is beneficial for using the front cover plate horizontally and for blocking light from the navigator body, thus optimizing the device's functionality.

[0018] 2. This utility model provides a drive wheel on the outer wall of the card block. When the drive card block contacts the outer wall of the connecting block, the drive wheel is driven to rotate inside the card block under the action of external force. This reduces the friction between the card block and the connecting block, making it easier to insert the card block into the card slot and achieve the locking purpose. In addition, the heat from the space between the front cover plate body and the navigator body can be transferred to the outside of the front cover plate body through the heat sink, so as to dissipate heat and improve the service life of the navigator body.

Detailed Implementation

[0029] 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. Example

[0030] The existing design has gaps between the front cover and the navigator, resulting in poor fit. In humid weather, water can easily seep between them, causing short circuits, touchscreen malfunctions, and difficulty in operating the navigator. This embodiment provides a waterproof and heat-dissipating front cover for the navigator, allowing the front cover body 1 to fit tightly and be fixed to the surface of the navigator body 2, reducing water seepage and significantly improving waterproofing. This enables the navigator to function normally in humid environments and facilitates user access and control of the navigator body 2. Please refer to... Figure 1 - Figure 7 The waterproof and heat-dissipating front cover of the navigator includes a front cover body 1 for covering the front end of the navigator body 2. A sealing gasket 102 is provided between the front cover body 1 and the navigator body 2 to prevent water seepage. A positioning assembly is provided on the front cover body 1. The positioning assembly includes a fixing block 4 for fixing and installing at the rear end of the front cover body 1, and a connecting block 5 for fixing and installing at the groove on the outer wall of the navigator body 2. The outer wall of the connecting block 5 has an inlet 501, and the outer end of the fixing block 4 is inserted into the inlet 501 to tighten the front cover body 1. The front cover plate 1 is fixed to the outer wall of the front end of the navigator body 2. During use, the display screen, control buttons, circuit connection ports and other structures that are prone to water ingress of the navigator body 2 are all located at the front end of the navigator body 2. The front cover plate 1 covers the front end of the navigator body 2, so that the display screen, control buttons, circuit connection ports and other structures that are prone to water ingress are covered and waterproofed. This prevents these structures from coming into contact with water, effectively blocks water intrusion, reduces the risk of damage to internal components, and allows the navigator to be viewed and used normally in humid environments.

[0031] To ensure a stable connection between the front cover body 1 and the navigator body 2, preventing loosening and detachment without adjustment, thus improving positioning stability and reliability and ensuring normal component operation, a locking block 402 is provided to limit its insertion into the connecting block 5. Figure 4 - Figure 6 As shown, the inner wall of the connecting block 5 has a slot 502 that communicates with the inlet 501. A driving block 402 that matches the slot 502 slides inside the fixing block 4. A compression spring 401 is fixedly installed inside the fixing block 4 to drive the driving block 402 into the slot 502. A transparent plate 101 is provided on the front cover body 1 to facilitate viewing the content displayed on the navigator body 2. A light-blocking cloth 8 is provided on the outer wall of the transparent plate 101 to shield itself from light. In use, the fixing block 4 drives the block 402 into the inlet 501. When the block 402 moves to a position aligned with the slot 502, the compression spring 401... The pushing force pushes the locking block 402 outward, causing it to insert and lock into the slot 502. Multiple sets of structures, including the fixing block 4, locking block 402, inlet 501, and slot 502, are symmetrically distributed. The locking block 402, inserted and locked into the slot 502, restricts the fixing block 4 within the inlet 501, thereby securing the front cover body 1 to the front end of the navigator body 2. This prevents the front cover body 1 from moving freely, creating gaps between it and the outer wall of the navigator body 2, allowing water to seep in and affecting the waterproofing effect. Furthermore, the locking block 402, under the action of the compression spring 401, is tightly locked into the slot 502, forming a stable connection structure.

[0032] The drive block 402 is slidably connected inside the drive block 402, and the drive block 402 is fixedly connected to the compression spring 401. In use, the front cover body 1 is flipped down to cover the front end of the navigator body 2, and is engaged in the slot 502 by the drive block 402, thus fastening the front cover body 1 to the front end of the navigator body 2. When the front cover body 1 is opened, the user pushes the two sets of drive blocks 402 inward with two fingers. At this time, the compression spring 401 deforms, shortening the overall width of the fixing block 4, thereby allowing the drive block 402 to be disengaged from the slot 502, making it easy to open the front cover body 1 and operate the navigator body 2.

[0033] To facilitate operation of the navigator body 2, the front cover body 1 is rotatably connected to the moving block 301 via the linkage block 302. This allows the front cover body 1 to be rotated around the linkage block 302 to open it. Figure 2 - Figure 3As shown, a connecting box 3 is fixedly installed on the top of the front cover body 1, and a moving block 301 that slides horizontally is set inside the connecting box 3. The outer side of the moving block 301 is rotatably connected to a linkage block 302 that is fixedly installed with the front cover body 1 via a pin. The linkage block 302 and the moving block 301 provide continuous resistance through an internal damping structure, so that the front cover body 1 will not slide arbitrarily due to gravity or slight vibration during rotation, thus limiting the opening position of the front cover body 1, making it convenient for users to access and adjust the navigator body 2. In use, by first flipping the front cover body 1 downwards and then pushing the front cover body 1 towards the navigator body 2, the front cover body 1 is tightly attached to the surface of the navigator body 2, further improving the waterproof effect. Example

[0034] Based on Embodiment 1, in order to block the light from the navigator body 2 when the front cover body 1 is used horizontally, thereby optimizing the device's functionality, such as... Figure 1 - Figure 7 As shown, the device also has a transparent plate 101 on the front cover body 1 to facilitate viewing the content displayed on the navigator body 2, so that users can directly view the navigation content displayed on the screen of the navigator body 2, and further improve the airtightness between the front cover body 1 and the surface of the navigator body 2.

[0035] To facilitate the selection of applications based on usage needs and flexibly address different usage requirements, such as Figure 7 As shown, the outer wall of the front cover body 1 is rotatably equipped with a take-up roller for winding up the cover cloth 8 used to block the light transmission of the transparent plate 101, and the two ends of the take-up roller are equipped with torsion springs for winding and resetting. In use, by pulling the cover cloth 8 in the direction of the linkage block 302, the cover cloth 8 blocks the transparent plate 101, which is beneficial to the use of the front cover body 1 horizontally to block the light of the navigator body 2, and promotes the optimization of the equipment's function. When the cover cloth 8 is released, the torsion spring drives the take-up roller to rotate back, so that the cover cloth 8 is rewound onto the take-up roller.

[0036] The end of the covering cloth 8 is fixedly connected to a collar 801, and the collar 801 is hooked onto the hanging block 802 fixedly installed on the front cover body 1. When the covering cloth 8 is unfolded to cover the transparent plate 101, the covering cloth 8 is kept in that position by hooking the collar 801 onto the hanging block 802.

[0037] To facilitate the locking and engaging of the drive block 402 within the slot 502, a drive wheel 4021 is provided on the outer side of the drive block 402. When the drive block 402 contacts the outer wall of the connecting block 5, under the action of external force, the drive wheel 4021 pushes the drive block 402 into the fixed block 4, causing the compression spring 401 to deform. Figure 4 - Figure 5As shown, limit plates 6 are fixedly installed on both outer walls of the drive block 402. The two sets of limit plates 6 are limited and fitted against the inner side wall of the fixed block 4. The contact surface between the drive block 402 and the connecting block 5 is sloped, and a drive wheel 4021 is rotatably connected inside the drive block 402. Without external force, the limit plates 6 are limited and fitted against the inner side wall of the fixed block 4. For details, please refer to the attached diagram. Figure 5 Furthermore, during the pressing process, the drive wheel 4021 rotates inside the card block 402, which reduces the friction between the card block 402 and the connecting block 5, making it easier to insert the card block 402 into the card slot 502 and achieve the locking purpose.

[0038] A heat sink 7 for conducting heat is fixedly inserted through the front cover body 1. One end of the heat sink 7 is located between the front cover body 1 and the navigator body 2, and the other end is located outside the front cover body 1. It dissipates heat by transferring the heat in the space between the front cover body 1 and the navigator body 2 to the outside of the front cover body 1.
