Obviously, these conventional approaches increase the cost of manufacturing the product and the reliability of the mechanical structure is limited.

In this regard, the utility model provides a connection structure, a structural component and a terminal device, which can improve the reliability of the mechanical structure of the product.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1 and 2, a connection structure 100 according to an embodiment of the present utility model includes a connection post 10 and a magnetic ring structure 20.

One end of the connecting column 10 is used for being fixedly connected to the first structural member 201, the other end of the connecting column 10 is used for being connected with the second structural member 202, and the connecting column 10 can be deformed from an initial state to a bending state under the action of external force. The magnetic ring structure 20 at least includes an inner magnetic ring 21 and an outer magnetic ring 23, the inner magnetic ring 21 is used for sleeving on the periphery side of the connecting column 10, the outer magnetic ring 23 is sleeved on the outer side of the connecting column 10 and is configured to be abutted against the first structural member 201, a gap is formed between the outer magnetic ring 23 and the outer periphery surface of the connecting column 10, and the outer magnetic ring 23 acts on the inner magnetic ring 21 through magnetic force so as to apply force for returning from a bending state to an initial state to the connecting column 10.

In the connection structure 100 provided in the embodiment of the present utility model, after the connection post 10 receives an impact external force, the connection post 10 can deform from an initial state to a bent state, and release plastic energy to avoid breaking. Because the inner magnetic ring 21 is sleeved on the periphery of the connecting column 10, the connecting column 10 will move with the inner magnetic ring 21 after being deformed, and the outer magnetic ring 23 will act on the inner magnetic ring 21 by magnetic force, so that the inner magnetic ring 21 drives the connecting column 10 to return to the initial state. When the connecting column 10 is subjected to the instant impact of external force, the connecting column 10 can alleviate the stress generated by the impact external force through deformation, and the magnetic ring structure 20 can buffer and recover the deformation of the connecting column 10, so that the reliability of the mechanical structure connected through the connecting structure 100 can be improved. Compared with the conventional means, the connecting structure 100 of the present utility model is convenient to manufacture and has lower cost, and can effectively improve the reliability of the mechanical structure.

It will be appreciated that in the absence of external forces, the inner magnet ring 21 tends to assume an initial position, i.e. a position in which the connection post 10 is in an initial state, under the magnetic force of the outer magnet ring 23. The outer diameter of the inner magnet ring 21 is smaller than the outer diameter of the outer magnet ring 23, so that the inner magnet ring 21 is displaced relative to the outer magnet ring 23 when the connecting post 10 is deformed, and at this time, the outer magnet ring 23 generates a magnetic repulsive force to the inner magnet ring 21, so that the inner magnet ring 21 tends to be in the initial position.

It will be appreciated that the shape of the connection post 10 is not limited as long as the inner magnet ring 21 can be tightly sleeved on the circumferential side of the connection post 10. The connecting column 10 is illustratively a cylindrical connecting column 10, so as to ensure that the connecting column can bend and deform to the same extent when being subjected to external forces with the same magnitude in any direction, and further release plastic energy, thereby ensuring the reliability of the whole structure.

Referring to fig. 1 and 2, in some embodiments, the magnetic ring structure 20 further includes at least one transition magnetic ring 22, the transition magnetic ring 22 is sleeved on the outer side of the connection post 10, two sides of the transition magnetic ring 22 along the length extension direction of the connection post 10 are magnetically connected with the inner magnetic ring 21 and the outer magnetic ring 23, a gap is formed between the transition magnetic ring 22 and the outer peripheral surface of the connection post 10, and a gap is formed between the transition magnetic ring 22 and the first structural member 201. It can be appreciated that the magnetic force acting on the inner magnetic ring 21 can be increased by the transition magnetic ring 22, and the inner magnetic ring 21 can obtain a larger magnetic force acting after deviating from the initial position, so that the buffer effect of the connecting post 10 after receiving the external force is better, and the shock resistance of the connecting structure 100 is also better.

It will be appreciated that the transition magnet 22 will also be displaced when the connection post 10 is deformed, and the transition magnet 22 will also cushion the deformation of the connection post 10 by the magnetic force of the outer magnet 23 and will apply a force to return to the original state to the connection post 10 via the inner magnet 21.

Referring to fig. 1 and 2, in some embodiments, the inner magnetic ring 21, the outer magnetic ring 23 and the transition magnetic ring 22 are all circular magnetic rings, and the inner magnetic ring 21, the outer magnetic ring 23 and the transition magnetic ring 22 are coaxially disposed when the connecting post 10 is in the initial state; the inner diameter of the outer magnet ring 23 is larger than the outer diameter of the inner magnet ring 21, the inner diameter of the transition magnet ring 22 is larger than the inner diameter of the inner magnet ring 21 and smaller than the outer diameter of the inner magnet ring 21, and the outer diameter of the transition magnet ring 22 is larger than the inner diameter of the outer magnet ring 23 and smaller than the outer diameter of the outer magnet ring 23. When the inner magnet ring 21, the transition magnet ring 22 and the outer magnet ring 23 are magnetically connected, the inner magnet ring 21, the transition magnet ring 22 and the outer magnet ring 23 are sequentially tangent, and the magnet ring structure 20 is compact in structure, and after the inner magnet ring 21 and/or the transition magnet ring 22 are displaced, a larger magnetic force effect is obtained so as to buffer and recover the deformation of the connecting column 10.

In some other embodiments, the inner magnet ring 21, the outer magnet ring 23, and the transition magnet ring 22 may also be other shapes, such as elliptical ring magnet rings.

Referring to fig. 1 and 2, in some embodiments, the inner magnet ring 21, the transition magnet ring 22, and the outer magnet ring 23 are configured to magnetically connect in sequence along the direction of the first structural member 201 to the second structural member 202. When the inner magnet ring 21, the transition magnet ring 22 and the outer magnet ring 23 are mounted, they are connected in sequence. It can be appreciated that, since the outer magnetic ring 23 abuts against the first structural member 201 and the inner magnetic ring 21 is close to the first structural member 201, the installed magnetic ring structure 20 can be partially accommodated in the first structural member 201, and the distance between the first structural member 201 and the second structural member 202 can be changed according to the requirement, which is not limited by the length of the connecting post 10.

Illustratively, the first structural member 201 is provided with a groove 201a, the connecting post 10 is connected to the bottom wall of the groove 201a, the magnetic ring structure 20 is accommodated in the groove 201a, and the outer magnetic ring 23 abuts against the side wall of the groove 201a. In this way, the magnetic ring structure 20 can be accommodated by the groove 201a, and the space of the connecting post 10 extending from the groove 201a is not occupied.

In some other embodiments, the inner magnet ring 21, the transition magnet ring 22, and the outer magnet ring 23 are configured to magnetically connect in sequence along the direction of the second structural member 202 to the first structural member 201. When the inner magnet ring 21, the transition magnet ring 22 and the outer magnet ring 23 are mounted, they are connected in sequence. It will be appreciated that, since the outer magnetic ring 23 abuts against the first structural member 201 and the inner magnetic ring 21 is far away from the first structural member 201, a space is necessarily provided between the position where the inner magnetic ring 21 is mounted on the connection post 10 and the first structural member 201, and thus the inner magnetic ring 21 acts on the connection post 10 to buffer and recover the deformation of the connection post 10.

Illustratively, the first structural member 201 is provided with a blocking ring surrounding the connecting post 10, and the inner magnetic ring 21, the transition magnetic ring 22 and the outer magnetic ring 23 are configured to be magnetically connected in sequence along the direction from the second structural member 202 to the first structural member 201, and the outer magnetic ring 23 abuts against the blocking ring.

Referring to fig. 2, in some embodiments, the cross-sections of the outer magnet ring 23, the transition magnet ring 22 and the inner magnet ring 21 are all circular, and the cross-sectional diameter of the outer magnet ring 23 is larger than the cross-sectional diameter of the transition magnet ring 22, and the cross-sectional diameter of the transition magnet ring 22 is larger than the cross-sectional diameter of the inner magnet ring 21. When the inner magnet ring 21 is displaced, the outer magnet ring 23 and the transition magnet ring 22 can exert stronger magnetic repulsive force on the inner magnet ring 21, or when the inner magnet ring 21 and the transition magnet ring 22 are displaced, the outer magnet ring 23 can exert stronger repulsive force on the inner magnet ring 21 and the transition magnet ring 22 so as to buffer and recover the deformation of the connecting column 10. Such an arrangement can increase the limit distance of the swing of the connection post 10 to improve the cushioning effect on the connection post 10.

It will be appreciated that the sum of the chord distance from the point of engagement of the inner magnet ring 21 with the transition magnet ring 22 to the lowest point of the transition magnet ring 22 and the chord distance from the point of engagement of the transition magnet ring 22 with the outer magnet ring 23 to the lowest point of the outer magnet ring 23 is the limit distance that the connecting post 10 can oscillate. It will be appreciated that the limit distance of oscillation of the connecting post 10 cannot exceed the maximum plastic deformation zone of the connecting post 10, and the maximum plastic deformation zone of the connecting post 10 is determined according to the material of the connecting post 10.

In some other embodiments, the inner magnetic ring 21 and the outer magnetic ring 23 may be provided with a larger number of transition magnetic rings 22, the transition magnetic rings 22 are sequentially magnetically connected, and the transition magnetic rings 22 on two sides of the connecting column 10 along the length extension direction of the connecting column 10 are respectively connected with the inner magnetic ring 21 and the outer magnetic ring 23, so as to increase the overall magnetic force of the magnetic ring structure 20 and improve the buffering effect on the connecting column 10.

In still other embodiments, the magnet structure 20 includes only an inner magnet ring 21 and an outer magnet ring 23, the outer magnet ring 23 being magnetically coupled to the inner magnet ring 21 to apply a magnetic force to the inner magnet ring 21. Illustratively, the outer diameter of the inner magnet ring 21 is greater than the inner diameter of the outer magnet ring 23 so that the outer magnet ring 23 can stabilize the magnetic force acting on the inner magnet ring 21.

In some embodiments, the connection post 10 comprises a resilient PVC connection post, a resilient plastic connection post, or a resilient metal connection post. Such a connection post 10 is capable of undergoing bending deformation and releasing plastic energy to relieve stress generated by an impact external force by deformation, and is capable of returning from a bent state to an initial state by the magnetic ring structure 20.

It will be appreciated that the buffer effect of the inner magnetic ring 21 on the connecting post 10 is different when the inner magnetic ring 21 is at different positions of the connecting post 10, that is, the closer the inner magnetic ring 21 is to the first structural member 201, the larger the magnetic force summation requirement in the magnetic ring structure 20 is, so that the buffer requirement on the whole connecting post 10 can be met.

Referring to fig. 2, in some embodiments, the length ratio L2 of the connecting column 10: l1 is 4:1. the distance between the contact position of the connecting post 10 and the inner magnetic ring 21 and the end of the connecting post 10 fixedly connected to the first structural member 201 is L1, and the distance between the contact position of the connecting post 10 and the inner magnetic ring 21 and the end of the connecting post 10 far from the first structural member 201 is L2. In this way, the magnetic coil structure 20 can be as close to the first structural member 201 as possible, and the buffering requirement for the whole connecting column 10 can be satisfied. It will be appreciated that the ratio of the lengths of L1 and L2 is determined according to the material of the connecting column 10, and the requirement of deformation needs to be met, and the requirement of impact and vibration acceleration needs to be met by the connecting column 10 as a whole. Illustratively, the impact requirement of the connection post 10 satisfies 10G, the magnetic force of the magnet ring structure 20 is 2.5N in total, then L2: the L1 ratio is recommended to be 4:1. of course, in other embodiments, the length ratio L2 of the connecting column 10: l1 is not limited to 4:1, for example, the magnetic force of the magnetic ring structure 20 increases in total, and the length ratio L2 of the connection post 10: l1 may also be increased; for another example, the impact requirement of the connection post 10 is reduced, and the length ratio L2 of the connection post 10: l1 may also be increased.

Referring to fig. 3, the present utility model further provides a structural assembly 1000, which includes a first structural member 201, a second structural member 202, and a connecting structure 100.

Wherein the first structural member 201 is provided with a recess 201a. One end of the connecting column 10 is fixedly connected to the bottom wall of the groove 201a, the other end of the connecting column 10 is connected with the second structural member 202, and the outer magnetic ring 23 abuts against the side wall of the groove 201a.

In the structural assembly 1000 provided in the embodiment of the present utility model, when the structural assembly 1000 is impacted by an external force, the first structural member 201 and the second structural member 202 will deviate, so that the connecting column 10 will deform from an initial state to a bent state, and release the plastic energy, so as to avoid the breakage of the connecting column 10. Because the inner magnetic ring 21 is sleeved on the peripheral side of the connecting column 10, the outer magnetic ring 23 abuts against the side wall of the groove 201a, after the connecting column 10 is deformed, the inner magnetic ring 21 is carried to move, and the outer magnetic ring 23 acts on the inner magnetic ring 21 by magnetic force, so that the inner magnetic ring 21 drives the connecting column 10 to return to the initial state. When the connecting column 10 is subjected to the instant impact of external force, the connecting column 10 can release the stress generated by the impact external force through deformation, and the magnetic ring structure 20 can buffer and recover the deformation of the connecting column 10, so that the reliability of the structural assembly 1000 can be improved. Compared with the conventional means, the structural component 1000 of the present utility model is convenient to manufacture and has lower cost, and the reliability of the structural component 1000 can be effectively improved.

It will be appreciated that the first structural member 201 and the second structural member 202 are any two structural members that may be connected by the connecting post 10. For example, the housing and the structural connection between the housings. As another example, a structural connection between the PCB board and the housing. Also for example, a structural connection between the PCB board and the PCB board.

Illustratively, the first structural member 201 is integrally formed with the connector post 10. For example, the first structural member 201 and the connecting post 10 are made of PVC, plastic, metal having elastic properties.

Referring to fig. 3, in some embodiments, the notch of the groove 201a is provided with a step surface 2011, and the step surface 2011 is inclined away from the connecting post 10 along the direction from the first structural member 201 to the second structural member 202, and the outer magnetic ring 23 abuts against the step surface 2011. When the magnetic ring structure 20 is installed, the outer magnetic ring 23 is sleeved on the connecting post 10, is placed in the groove 201a along the direction from the second structural member 202 to the first structural member 201, and abuts against the step surface 2011. This facilitates the installation of the magnet ring structure 20 and is sufficiently held against the side walls of the recess 201a.

In some embodiments, the inner magnet ring 21 is first fixedly connected to the connecting post 10 when the magnet ring structure 20 is installed. Then, other magnetic rings are sequentially sleeved on the connecting column 10, and the outer magnetic ring 23 abuts against the side wall of the groove 201a, so that the installation is realized. Such a magnetic ring structure 20 can be accommodated in the recess 201a without occupying the space in which the connection post 10 extends from the recess 201a.

The magnetic ring structure 20 includes an inner magnetic ring 21, a transition magnetic ring 22 and an outer magnetic ring 23 which are magnetically connected in sequence, wherein after the inner magnetic ring 21 is fixedly connected with the connecting post 10, the transition magnetic ring 22 is magnetically connected with the inner magnetic ring 21 in sequence, the outer magnetic ring 23 is magnetically connected with the transition magnetic ring 22, and the outer magnetic ring 23 abuts against the step surface 2011 of the groove 201a. The magnet ring structure 20 is convenient to assemble, and each magnet ring is stable in magnetic connection and can be matched with the groove 201a stably.

For example, the inner magnet ring 21 may be fixed to the circumferential side of the connection post 10 by an in-mold injection molding or a hot pressing process. To ensure that the inner magnet ring 21 is stably attached to the connection post 10, and to prevent the inner magnet ring 21 from moving on the connection post 10. Of course, the inner magnet ring 21 may be only fitted around the periphery of the connection post 10 and not fixedly connected to the connection post 10.

The outer magnet ring 23 may be fixed to the side wall of the groove 10 by an in-mold injection molding or a hot pressing process, for example. To ensure that the outer magnet 23 is stably connected to the first structural member 201, preventing the outer magnet 23 from moving. Of course, the outer magnetic ring 23 may only abut against the side wall of the groove 10, and not be fixedly connected with the side wall of the groove 10.

In other embodiments, the side wall of the groove 201a is further provided with an annular groove, and the outer magnetic ring 23 abuts against the side wall of the annular groove, and the side wall of the annular groove is disposed along the length extending direction of the connecting post 10.

Referring to fig. 3, in some embodiments, the structural assembly 1000 further includes a screw 203, the other end of the connecting post 10 is provided with a threaded hole 10a, and the screw 203 is threaded through the second structural member 202 and is screwed into the threaded hole 10a. When the first structural member 201 and the second structural member 202 are mounted, the first structural member 201 and the second structural member 202 are fastened and connected by threading the first structural member 202 through the screw 203 and the screw hole 10a.

In some other embodiments, the other end of the connection post 10 may also be connected to the second structural member 202 by a snap-fit structure. For example, the second structural member 202 has a clamping hole, a clamping groove is formed in the clamping hole, a clamping hook is formed on the periphery of the connecting column 10, the connecting column 10 is placed in the clamping hole, and the clamping hook is embedded in the clamping groove, so that the first structural member 201 and the second structural member 202 are fastened and connected.

Referring to fig. 1 to 3, the present utility model further provides a terminal device, which includes the above-mentioned structural component 1000.

In the terminal device provided by the embodiment of the utility model, when the terminal device is impacted by external force, the first structural member 201 and the second structural member 202 are offset, so that the connecting column 10 is deformed from an initial state to a bending state, and the plastic energy is released, so that the connecting column 10 is prevented from being broken. Because the inner magnetic ring 21 is sleeved on the peripheral side of the connecting column 10, the outer magnetic ring 23 abuts against the side wall of the groove 201a, after the connecting column 10 is deformed, the inner magnetic ring 21 is carried to move, and the outer magnetic ring 23 acts on the inner magnetic ring 21 by magnetic force, so that the inner magnetic ring 21 drives the connecting column 10 to return to the initial state. When the connecting column 10 is subjected to the instant impact of external force, the connecting column 10 can release the stress generated by the impact external force through deformation, and the magnetic ring structure 20 can buffer and recover the deformation of the connecting column 10, so that the reliability of the structural assembly 1000 can be improved. Compared with the conventional means, the terminal equipment has high reliability of the mechanical structure and can meet the stable operation in any state.

The terminal equipment can be a vehicle-mounted terminal, and can ensure that the vehicle-mounted terminal has better anti-seismic and shock resistance when working under any road condition, so that the mechanical shock resistance is greatly improved, and the stable working of the vehicle-mounted terminal is ensured.

The terminal equipment can be outdoor terminal equipment, and even if the outdoor terminal equipment is impacted by external force such as wind power and the like when the outdoor terminal equipment is placed outdoors, the internal structure of the outdoor terminal equipment is not damaged, so that the outdoor terminal equipment can work stably in any environment.

It is understood that the terminal device of the present utility model is not limited to the above-listed terminal devices, but may be other terminal devices with high mechanical structure reliability, which will not be described in detail.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the specification and drawings of the present utility model or direct/indirect application in other related technical fields are included in the scope of the present utility model.
