Abstract
Description
Technical Field
[0001] The utility model relates to the field of hooks, in particular to an elastic hook mechanism. Background Art
[0002] In-vehicle multimedia players are usually fixed to the vehicle body by screws, clips or specific mounting brackets. These fixing methods can ensure that the player will not shake or shift during driving, thereby ensuring driving safety.
[0003] Although these limiting structures can ensure that the player will not shake or shift during driving, in some extreme cases (such as sudden braking, collision, etc.), the player may still be out of the positioning slot due to inertia, causing safety hazards. In order to improve the fixing stability, additional fixing measures may be required, such as adding anti-slip pads, using more durable materials, etc., but these measures may increase costs and installation difficulties. If the positioning slot or limiting structure fails or is damaged, the entire workbench may need to be disassembled for repair or replacement, which may involve complicated disassembly and installation processes, increasing the difficulty and cost of maintenance. In addition, since this fixing structure is usually tightly connected to other components inside the vehicle, special care must be taken during the repair process to avoid damaging other components.
[0004] Therefore, designing an elastic hook mechanism that is easy to assemble and disassemble and has strong fixing stability has become an urgent problem that technicians in this field need to solve. Utility Model Content

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0031] See also Figures 1 to 7 , provides an elastic hook mechanism, including a first connecting member 1, a second connecting member 31, a player body 4 and a control panel 5; one end of the first connecting member 1 is fixed on the control panel 5, and the other end is provided with a hook 11 and a plug rod 12, and the plug rod 12 is sleeved with a spring 2, which can offset the stress in the event of sudden braking, shaking, collision, etc. of the car during driving, thereby improving the connection stability of the control panel 5, the hook 11 is respectively arranged on both sides with the plug rod 12 as the central axis X, the player body 4 is provided with a first receiving wall 3, the first receiving wall 3 is provided with a support member 32 corresponding to the first connecting member 1, the support member 32 is provided with a first connecting hole 321 and a second connecting hole 322, the first connecting hole 321 and the second connecting hole 322 are connected to form Cavity, after the first connecting member 1 is inserted into the cavity, the spring 2 is compressed by the supporting top walls 324 on both sides of the first connecting hole 321, and the hook 11 is squeezed with the inner wall of the second connecting hole 322 when passing through the entrance of the second connecting hole 322, and the hook 11 is bent toward the central axis X of the insertion rod 12 until the hook 11 is separated from the inner wall of the second connecting hole 322, and the hook 11 is snap-fitted with the supporting side walls 323 on both sides of the second connecting hole 322. At the same time, the player body 4 and the control panel 5 are connected through the second connecting member 31, and the first connecting member 1 and the second connecting member 31 are connected at the same time, which greatly enhances the connection stability between the control panel 5 and the player body 4. At the same time, the second connecting member 31 gives support force to the first connecting member 1 to prevent the elastic force of the spring 2 from deforming the hook 11 and disconnecting it.
[0032] The contact surface between the supporting side wall 323 and the hook 11 is a supporting surface 325. The supporting surface 325 is an inclined surface that matches the inclination angle of the hook 11. The hook 11 is made of POM material. When the control panel 5 is installed, the hook 11 is bent toward the middle with the central axis X of the insertion rod 12 under the action of the thrust until the hook 11 passes through the connecting hole. After that, the first connecting member 1 cannot be removed and will not be deformed because the hook 11 conflicts with the supporting surface 325.
[0033] See also Figure 3-Figure 5 A barb 13 is provided at the connection between the first connecting member 1 and the control panel 5, and the control panel 5 is provided with a corresponding socket and a second receiving wall 51. After the first connecting member 1 is inserted into the socket, the barb 13 and the second receiving wall 51 are in contact with each other to form a snap connection.
[0034] See also Figure 8 The second connecting member 31 includes a shaft rod 311, a button 312, a sleeve 313 and a buckle 314. The second connecting member 31 is fixed to the first receiving wall 3 through the shaft rod 311. The button 312 and the buckle 314 protrude from the surface of the first receiving wall 3.
[0035] The shaft 311 is inserted into the sleeve 313, and the button 312 is integrally provided with the sleeve 313. By pressing the button 312, the sleeve 313 can be rotated around the shaft 311. The buckle 314 is fixed to one side of the sleeve 313 and is integrally provided. When the sleeve 313 rotates, the buckle 314 also rotates.
[0036] See also Figure 2 The second receiving wall 51 of the control panel 5 is provided with a first plug hole 52 corresponding to the buckle 314. When the insertion rod 12 of the first connecting member 1 is inserted into the first connecting hole 321 of the supporting member 32, the buckle 314 is also inserted into the first plug hole 52 and engaged therewith. When the button 312 is pressed to make the sleeve 313 drive the buckle 314 to rotate, the buckle 314 will be disengaged from the first plug hole 52. After the buckle 314 is disengaged from the first plug hole 52, the spring 2 pops out the control panel 5 until the hook 11 contacts the supporting surface 325. Then, the control panel 5 can be disconnected from the connection with the barb 13 and taken out. The direction of the hook 11 before it stops popping out is V, which is the direction in which the control panel 5 is separated from the player body 4.
[0037] See also Figure 3 and 9 The support surface 325 is an inclined plane. When an impact occurs, the support surface 325 generates a reverse support force F2 on the hook 11. The support force F2 can be decomposed into two components, namely F21 and F22. F22 is the component F22 that causes the hook to deform outward and open. This component F22 offsets the stress of the hook 11 deformed by the impact, so that the two hooks can still be securely supported, thereby preventing the hook 11 from falling off. Because F22=F2cosθ, when the support surface 325 is perpendicular to the direction of the elastic force F1, F22=0 at this time. The support surface 325 cannot prevent the hook 11 from deforming and bending in the direction of the axis X of the plug rod 12, which can easily cause the hook 11 to fall off. Therefore, the angle θ is generally set to 30 degrees-45 degrees.
[0038] The utility model provides an elastic hook 11 mechanism. The first connecting member 1 is used in conjunction with the second connecting member 31. There is no need to increase the rigidity of the hook 11 or the width of the supporting area. Instead, the hook 11 is specially designed so that the elastic direction of the spring 2 is not perpendicular to the supporting surface 325, forming an inclined angle. When the hook 11 pops out rapidly, the supporting surface 325 and the hook 11 form a conflict to prevent the pop-up. At this time, the control panel can be taken away by hand to complete the disassembly of the control panel 5. The first connecting member 1 improves the connection firmness of the control panel 5. Since the car will be bumpy during the formation process, the first connecting member 1 can also reduce the impact and vibration caused by the uneven road surface. While ensuring the stability of the connection, the utility model also has the characteristics of convenient disassembly and assembly.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
