Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted equipment, in particular to an impact-resistant vehicle-mounted navigation support structure. Background Art

[0002] The in-car navigation system is an important part of the car computer. The driver can view the navigation route, watch and listen to audio entertainment programs, etc. through the display screen on the host. The existing in-car navigation host is generally fixedly connected to the center console shell in the car through fasteners. When the car is driven on bad roads for a long time, the support structure connecting the host and the center console shell is easily deformed by the long-term impact kinetic energy. At the same time, the parts inside the host are also easily affected by the impact and loosened. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an impact-resistant vehicle-mounted navigation support structure.

[0004] The technical solution of the utility model is: an impact-resistant vehicle navigation support structure, including an outer frame and a connecting plate, the outer frame is fixedly connected to the host, and the connecting plate is fixedly connected to the central control shell. The outer frame is connected to the connecting plate through an elastic connecting mechanism, and the elastic connecting mechanism includes a groove, a slider and a spring. A groove is provided on one side of the outer frame close to the connecting plate, and a sliding slider is provided in the groove. The two ends of the slider are respectively connected to the two ends of the groove through a spring, and the slider is fixedly connected to the connecting plate.

[0005] Furthermore, an inner groove matching the mainframe is provided on one side of the outer frame away from the connecting plate, and a heat dissipation metal sheet is provided on the bottom surface of the inner groove. The heat dissipation metal sheet is attached to the mainframe and penetrates the outer frame.

[0006] Furthermore, a fin is provided on one side of the heat dissipation metal sheet close to the connection plate.

[0007] Furthermore, a plurality of positioning blocks are provided on the outer frame, and positioning grooves matching the positioning blocks are provided on the connecting plate.

[0008] Furthermore, a plurality of second positioning holes are provided on the connecting plate, and each of the second positioning holes is provided with a fastener, which passes through the second positioning holes and is screwed into the central control shell.

[0009] Furthermore, a plurality of buckles matching the central control shell are provided on a side of the connecting plate close to the central control shell.

[0010] Furthermore, an elastic pad is provided between the connecting plate and the central control shell, and the elastic pad is fitted with the connecting plate and the central control shell.

[0011] Compared with the prior art, the utility model has the advantages that the outer frame is connected to the connecting plate through an elastic connecting mechanism, thereby indirectly realizing the elastic connection between the host and the central control shell. When the central control shell moves with the car, when the bumpiness is too large, the host is subjected to a large impact kinetic energy. At this time, the slider causes the spring to deform, and the deformation of the spring is used to absorb the impact kinetic energy, thereby alleviating the damage to the connection between the outer frame and the connecting plate caused by the impact, and at the same time weakening the impact on the parts inside the host.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, 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 belong to the scope of protection of the utility model.

[0019] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 4As shown, an impact-resistant vehicle navigation support structure includes an outer frame 1 and a connecting plate 2. The outer frame 1 is provided with a plurality of first positioning holes 14, each of which is provided with a fastener, which passes through the first positioning holes 14 and is screwed into the host. The connecting plate 2 is fixedly connected to the central control shell. The connecting plate 2 is provided with a plurality of second positioning holes 23, and the central control shell is fixedly connected to the connecting plate 2 through the cooperation of the fasteners and the second positioning holes 23.

[0021] The outer frame 1 is connected to the connecting plate 2 through an elastic connection mechanism 16. The elastic connection mechanism 16 includes a groove 161, a slider 162 and a spring 163. A groove 161 is provided on one side of the outer frame 1 close to the connecting plate 2. A slider 162 is provided in the groove 161. The slider 162 can move along the length direction of the groove 161. A damping plate is provided on the bottom surface of the groove 161, and the bottom surface of the slider 162 contacts the damping plate. The two ends of the slider 162 are respectively connected to the two ends of the groove 161 through springs 163. The slider 162 is provided with a plurality of threaded holes, and bolts 24 are provided at positions corresponding to the threaded holes on the connecting plate 2. The slider 162 is fixedly connected to the connecting plate 2 through the bolts 24. The host is elastically connected to the central control shell through the elastic connection mechanism 16. When the central control shell is greatly bumped with the movement of the car, the host moves relative to the connecting plate 2 with the outer frame 1, so that the slider 162 applies an external force to the spring 163, and the deformation of the spring 163 is used to absorb part of the impact kinetic energy. The connection between the outer frame 1 and the connecting plate 2 is prevented from loosening due to deformation, and the parts inside the main unit are protected from damage due to bumps.

[0022] An inner groove 11 matching the main unit is provided on one side of the outer frame 1 away from the connecting plate 2, and a heat dissipation metal sheet 12 is provided on the bottom of the inner groove 11. The heat dissipation metal sheet 12 is attached to the main unit and penetrates the outer frame 1. The heat generated by the operation of the main unit is dissipated by utilizing the good thermal conductivity of the heat dissipation metal sheet 12. Fins 121 are provided on one side of the heat dissipation metal sheet 12 close to the connecting plate 2, and the contact surface between the heat dissipation metal sheet 12 and the air is increased by utilizing the fins 121, thereby improving the heat dissipation capacity of the heat dissipation metal sheet 12. A plurality of positioning blocks 15 are provided on the outer frame 1, and a positioning groove 25 matching the positioning blocks 15 is provided on the connecting plate 2. By utilizing the cooperation between the positioning blocks 15 and the positioning groove 25, the relative positions of the outer frame 1 and the connecting plate 2 can be quickly determined, so that the connecting plate 2 can be assembled onto the elastic connecting mechanism 16.

[0023] A plurality of buckles 22 for matching the central control shell are provided on one side of the connecting plate 2 close to the central control shell. The connecting plate 2 is quickly and conveniently positioned with the central control shell through the buckles 22, which facilitates the subsequent installation of fasteners. An elastic pad 21 is provided between the connecting plate 2 and the central control shell, and the elastic pad 21 is fitted with the connecting plate 2 and the central control shell. The elastic force generated by the deformation of the elastic pad 21 is used to reinforce and prevent the fasteners connecting the central control shell and the connecting plate 2 from loosening. At the same time, the elastic pad 21 has a certain buffering capacity, which can absorb part of the impact kinetic energy and reduce the damage to the connection between the connecting plate 2 and the central control shell caused by the impact.

[0024] The working principle of the specific implementation of the utility model is as follows: the main unit is elastically connected to the central control shell through the elastic connection mechanism 16. When the central control shell moves with the car and experiences a large bump, the main unit moves with the outer frame 1 relative to the connecting plate 2. At this time, the slider 162 deforms the spring 163, and the deformation of the spring 163 is used to absorb the impact kinetic energy during the bump. This reduces the damage to the connection between the main unit and the central control shell caused by the impact, and prevents the internal parts of the main unit from loosening or falling off due to the bump.
