Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted accessories, and in particular to a multifunctional vehicle-mounted electronic equipment supporting device installed on a sun visor. Background Art

[0002] In the prior art, when a driver uses an electronic device, he needs to lower his head to watch the electronic device. When the head starts to tilt forward from an upright position, the muscles of the neck and upper back need to provide more strength to support the head, so the pressure on the neck will increase significantly. Specifically, when the angle of the head tilting forward increases, the torque acting on the cervical spine will also increase, and the neck muscles must work harder to keep the head stable.

[0003] Estimates based on anatomical and biomechanical principles:

[0004] When the head is upright, it weighs about 5 kg.

[0005] When the head is tilted 15 degrees, the load on the cervical spine is about 10 kg (twice the weight of the head).

[0006] When the head is tilted 30 degrees, this figure may rise to around 15 kg (3 times the weight of the head).

[0007] When the head is tilted 45 degrees, the load on the cervical spine may reach about 20 kilograms (4 times the weight of the head).

[0008] When the head is tilted to 60 degrees, the load on the cervical spine may be as high as 30 kg (6 times the weight of the head).

[0009] These numbers are not exact scientific measurements, but they suggest that looking down at an electronic device like a phone or tablet can cause neck pain and shoulder and neck strain because the muscles and ligaments are put into an unnatural state of stretch. Summary of the invention

[0010] The main purpose of the present invention is to propose a multifunctional vehicle-mounted electronic equipment support device installed on the sun visor, which is designed to adjust the angle between the head and the cervical spine when the user uses the electronic equipment, reduce the pressure of the head on the cervical spine and neck muscles, and thus alleviate the shoulder and neck fatigue caused by watching and using electronic equipment.

[0011] To achieve the above-mentioned purpose, the present invention proposes a multifunctional vehicle-mounted electronic equipment supporting device installed on a sun visor, comprising:

[0012] A clamping member for clamping to a sun visor;

[0013] A first mounting seat, connected to the clamping member so as to be rotatably adjustable about an axis extending in a first direction;

[0014] A plurality of connecting arms, wherein the plurality of connecting arms are rotatably connected to each other, and the plurality of connecting arms include a first connecting arm and a second connecting arm, wherein an end of the first connecting arm away from the second connecting arm is rotatably connected to the first mounting seat, and an end of the second connecting arm close to the first connecting arm is rotatably connected to the first connecting arm;

[0015] A second connecting seat is connected to an end of the second connecting arm away from the first connecting arm so as to be rotatably adjusted around an axis extending in a second direction; and

[0016] Two clamping members are arranged opposite to each other and are respectively connected to the second connection seat; the two clamping members can move relative to each other so that the clamping distance defined between the two clamping members can be changed to clamp electronic devices of different specifications.

[0017] In one embodiment, the clamping member has:

[0018] a support plate, connected to one side of the first mounting seat in a rotatable and adjustable manner around an axis extending in a first direction; and

[0019] The clamping plate is arranged opposite to the support plate to define a clamping space therebetween. One end of the clamping plate is connected to one end of the support plate, and the other end of the clamping plate can be elastically movable relative to the support plate.

[0020] In one embodiment, one end of the clamping plate is fixedly connected to the support plate, and the material of the clamping plate is an elastic material; or,

[0021] A torsion spring is arranged between one end of the clamping plate and the supporting plate.

[0022] In one embodiment, the first mounting seat is provided with an elongated slot extending along the third direction;

[0024] The fastening assembly comprises a screw rod and a nut, wherein one end of the screw rod is fixedly connected to the support plate, and the other end of the screw rod passes through the elongated slot, and the nut is threadedly installed on the other end of the screw rod.

[0025] In one embodiment, a gasket is provided between the nut and the first connecting seat.

[0026] In one embodiment, the plurality of connecting arms are rotatably connected about an axis extending in the second direction;

[0027] The first connecting arm is connected to the first connecting seat in a rotationally adjustable manner around an axis extending along the second direction, and the second connecting arm is connected to the second connecting seat in a rotationally adjustable manner around an axis extending along the third direction.

[0028] In one embodiment, a spherical accommodating cavity is provided on one side of the second connecting seat close to the second connecting arm, and one end of the second connecting arm close to the second connecting seat is spherically arranged and inserted into the spherical accommodating cavity and hingedly connected to the second mounting seat.

[0029] In one embodiment, the second connecting arm is bent around an axis extending along the second direction; and / or,

[0030] The second connecting arm is telescopically arranged.

[0031] In one embodiment, one end of the first mounting seat close to the first connecting arm is bent around an axis extending along the second direction, and one end of the first connecting arm close to the first mounting seat is bent around an axis extending along the second direction, so that when the first connecting arm is rotated relative to the first mounting seat to adjust to a minimum angle, an accommodating space for accommodating the clamping member is formed between the first mounting seat and the first connecting arm.

[0032] In one embodiment, a shock absorbing layer is provided on the contact surface between the two clamping members and the electronic device; and / or an anti-slip layer is provided on the contact surface between the two clamping parts and the electronic device.

[0033] The technical solution of the present invention is firmly fixed on the sun visor of the vehicle by a clamping member, so that the entire device will not loosen or fall off easily.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] like Figure 1 and Figure 2 As shown, a multifunctional vehicle-mounted electronic equipment supporting device 100 installed on a sun visor provided by the present invention comprises a clamping member 1, a first mounting seat 2, a plurality of connecting arms 3, a second connecting seat 4, and two clamping members 5. The clamping member 1 is used to clamp to the sun visor; the first mounting seat 2 is rotatably and adjustably connected to the clamping member 1 around an axis extending in a first direction; the plurality of connecting arms 3 are rotatably and adjustably connected to each other, and the plurality of connecting arms 3 comprise a first connecting arm 31 and a second connecting arm 32, the end of the first connecting arm 31 away from the second connecting arm 32 is rotatably and adjustably connected to the first mounting seat 2, and the end of the second connecting arm 32 close to the first connecting arm 31 is rotatably and adjustably connected to the first connecting arm 31; the second connecting seat 4 is rotatably and adjustably connected to the end of the second connecting arm 32 away from the first connecting arm 31 around an axis extending in a second direction; and the two clamping members 5 are arranged opposite to each other and are respectively connected to the second connecting seat 4; the two clamping members 5 can move relative to each other so that the clamping distance defined between the two clamping members 5 is changed to clamp electronic equipment of different specifications.

[0053] The technical solution of the present invention is firmly fixed on the sun visor of the vehicle by the clamping member 1, so that the whole device will not be easily loosened or fallen off. By rotating the first mounting seat 2 around the axis along the first direction, the user can adjust the overall angle of the supporting device as needed, so as to better watch or operate the electronic device. The connection of multiple connecting arms 3 can be adjusted in multiple directions, thereby improving the flexibility of adjustment. The second connecting seat 4 is located at the end of the second connecting arm 32 and can rotate around the third axis, further increasing the degree of freedom of device positioning. Two clamping members 5 are used to fix the electronic device, and the two clamping members 5 can stably clamp electronic devices of different specifications by moving closer or farther away from each other. By connecting the electronic device to the sun visor through the device and freely adjusting it in multiple directions, the angle between the head and the cervical spine is adjusted, and the pressure of the head on the cervical spine and neck muscles is reduced, thereby alleviating the shoulder and neck fatigue caused by watching and using electronic devices.

[0054] It is understandable that in order to reduce the weight of the supporting device, the first mounting base 2 and the plurality of connecting arms 3 in the present invention are made of strong and lightweight materials, such as aluminum alloy or high-quality engineering plastics. The second mounting base, the clamping member 5 and the part contacting the mobile phone are made of soft and non-slip materials, such as rubber or silicone.

[0055] In one embodiment, the clamping member 1 has a support plate 11 and a clamping plate 12. The support plate 11 is rotatably and adjustably connected to one side of the first mounting seat 2 around an axis extending in a first direction; the clamping plate 12 is arranged opposite to the support plate 11 to define a clamping space therebetween, one end of the clamping plate 12 is connected to one end of the support plate 11, and the other end of the clamping plate 12 can be elastically movable relative to the support plate 11.

[0056] It is understandable that the support plate 11 is capable of rotating about a direction extending along the first direction, and is capable of adjusting the angle of contact with the first mounting seat 2. The clamping plate 12 is arranged opposite to the support plate 11, and together forms a clamping space for gripping the sun visor. One end of the clamping plate 12 is connected to one end of the support plate 11, and the other end is designed to be elastically movable. This end of the clamping plate 12 can be moved away from the support plate 11 when receiving an external force, so as to clamp sun visors of different thicknesses and shapes, ensuring that the entire support device can be firmly fixed on the sun visor and will not easily slip or loosen. The elastic and movable setting also makes it more convenient for users to install, and the device can be quickly locked without complicated adjustments.

[0057] In one embodiment, one end of the clamping plate 12 is fixedly connected to the supporting plate 11 , and the material of the clamping plate 12 is an elastic material.

[0058] It is understandable that the clamping plate 12 itself is made of an elastic material, such as plastic, rubber or other polymer elastomers. This elastic material allows the clamping plate 12 to deform when subjected to external force. When the external force is removed, the clamping plate 12 will return to its original state due to its own elasticity, thereby tightly clamping the sun visor. This has a simple structure, does not require additional moving parts, and reduces the failure rate.

[0059] In one embodiment, a torsion spring is disposed between one end of the clamping plate 12 and the supporting plate 11 .

[0060] It is understandable that a torsion spring is provided between the clamping plate 12 and the support plate 11. The function of the torsion spring is to provide a preset torque. When the clamping plate 12 is manually pulled open, the torsion spring is twisted and stores energy. Once released, the resilience of the torsion spring will quickly return the clamping plate 12 to its initial position, thereby clamping the sun visor. This design can usually provide a greater clamping force and is suitable for thicker or harder sun visors, but may require additional maintenance to ensure the performance of the torsion spring.

[0061] It is understandable that the above two technical solutions can be used in combination. Both of the above two designs are intended to ensure that the clamping member 1 can be firmly fixed on the sun visor, and no matter what the thickness or shape of the sun visor is, sufficient clamping force can be provided to ensure the stability of the vehicle-mounted electronic equipment support device during driving.

[0062] like Figure 3 As shown, in one embodiment, an elongated groove 21 extending along a third direction is provided on the first mounting seat 2, and the multifunctional vehicle-mounted electronic equipment support device 100 installed on the sun visor also includes a fastening assembly 6, the fastening assembly 6 includes a screw 61 and a nut 62, one end of the screw 61 is fixedly connected to the support plate 11, and the other end is arranged to pass through the elongated groove 21, and the nut 62 is threadedly installed on the other end of the screw 61.

[0063] It is understandable that the first mounting seat 2 is provided with an elongated slot 21 extending along the third direction, and this elongated slot 21 can enable the screw 61 to move within a certain range. One end of the screw 61 is fixedly connected to the support plate 11, and when the support plate 11 rotates relative to the first mounting seat 2, the screw 61 will also rotate together. The other end of the screw 61 passes through the above-mentioned elongated slot 21 and extends out. The thread is installed at the protruding end of the screw 61. When the nut 62 is tightened, it will compress the first mounting seat 2, so that the screw 61 and the support plate 11 are fixed in a specific position to prevent further rotation. When the nut 62 is loosened, the screw 61 is allowed to move in the elongated slot 21, thereby realizing the angle adjustment of the support plate 11 relative to the first mounting seat 2. The user can adjust the angle of the support plate 11 by loosening the nut 62 to adapt to the sun visor of different models. After the adjustment is completed, tighten the nut 62 again to ensure that the entire device is firmly fixed on the sun visor and will not be displaced due to the vibration during the vehicle driving. In summary, the fastening assembly 6 can enhance the flexibility and stability of the multifunctional vehicle-mounted electronic device support device, allowing the user to easily adjust the position of the device according to actual needs while maintaining the safety and reliability of the device during use.

[0064] In one embodiment, a gasket is disposed between the nut 62 and the first connecting seat.

[0065] It is understandable that a gasket is provided between the nut 62 and the first connection seat. The gasket can increase the contact area between the nut 62 and the first connection seat, reduce local pressure, and prevent the nut 62 from directly pressing on the first connection seat to cause wear. At the same time, the friction force is also increased to prevent the nut 62 from loosening under vibration or external force. At the same time, the gasket can also be used to adjust the gap between the first connection seat and the support plate 11, which is very important for ensuring the stability and adjustment accuracy of the device. By selecting gaskets of different thicknesses, the relative positions of the various components can be fine-tuned to ensure the best assembly state.

[0066] In one embodiment, the multiple connecting arms 3 can be connected by rotation and adjustment around an axis extending in the second direction. The first connecting arm 31 is connected to the first connecting seat by rotation and adjustment around an axis extending in the second direction, and the second connecting arm 32 is connected to the second connecting seat 4 by rotation and adjustment around an axis extending in the third direction.

[0067] It can be understood that the first connecting wall can be rotated and adjusted around the axis extending in the second direction, and is connected to the first connecting seat, so that the first connecting arm 31 can rotate relative to the first mounting seat 2. The second connecting arm 32 and the first connecting wall can be rotated and adjusted around the axis extending in the second direction, so that the second connecting arm 32 can rotate relative to the first connecting wall, and the second mounting seat and the second connecting wall can be rotated and adjusted around the axis extending in the third direction, so that the second mounting seat can rotate relative to the second connecting wall. In this way, the degree of freedom of adjustment is further increased.

[0068] like Figure 4 As shown, in one embodiment, a spherical accommodating cavity is provided on one side of the second connecting seat 4 close to the second connecting arm 32, and one end of the second connecting arm 32 close to the second connecting seat 4 is spherically arranged and inserted into the spherical accommodating cavity and hingedly connected to the second mounting seat.

[0069] It can be understood that through this ball joint, users can flexibly adjust the position and angle of the electronic device to achieve the best viewing or operating position. In the limited space inside the car, this can provide full range of adjustment capabilities and a better user experience.

[0070] In one embodiment, the second connecting arm 32 is bent around an axis extending along the second direction.

[0071] It is understandable that by bending the second connecting arm 32, the screen of the electronic device can face the user without changing the relative position relationship between the multiple connecting arms 3. At the same time, the user can also adjust the position and angle of the electronic device according to personal preference or the layout of the vehicle.

[0072] In one embodiment, the second connecting arm 32 is telescopically arranged.

[0073] It is understandable that, through the telescopic second connecting arm 32, the user can adjust the length of the second connecting arm 32 as needed, which can make the electronic device closer to or farther away from the user to adapt to different usage scenarios and visual angles. In the case of limited space in the car, the telescopic connecting arm can be flexibly adjusted to avoid obstacles. When not in use, the telescopic connecting arm can be retracted to the shortest state to reduce the volume of the overall device, which is convenient for storage or switching positions in the car, ensuring that the installation position of the device neither blocks the line of sight nor hinders the operation of other vehicle control devices.

[0074] It should be noted here that the above two methods can be combined and set together, and their technical effects are the same as above, so no further elaboration is made here.

[0075] like Figure 5As shown, in one embodiment, one end of the first mounting seat 2 close to the first connecting arm 31 is bent around an axis extending along the second direction, and one end of the first connecting arm 31 close to the first mounting seat 2 is bent around an axis extending along the second direction, so that when the first connecting arm 31 is rotated relative to the first mounting seat 2 to adjust to the minimum angle, an accommodating space for accommodating the clamping member 5 is formed between the first mounting seat 2 and the first connecting arm 31.

[0076] It is understandable that by creating a storage space between the first mounting seat 2 and the first connecting arm 31, the limited space in the vehicle can be more effectively utilized. In particular, when the electronic device is not needed, it can be stored in this space to avoid occupying too much cockpit area and reduce the impact on the driver's field of vision and operation. At the same time, when the electronic device is not in use, the clamping part can be placed here to prevent the device from being randomly placed in the vehicle and being hit or scratched, especially during the driving of the vehicle, which can effectively protect the safety of the device and the user.

[0077] In one embodiment, a shock absorbing layer is provided on the contact surface between the two clamping members 5 and the electronic device.

[0078] It is understandable that the shock-absorbing layer can absorb the impact force caused by bumps, vibrations or sudden acceleration and deceleration during the driving of the vehicle, reduce the direct transmission of these forces to the electronic device, and reduce the risk of damage to the electronic device, especially for electronic devices with fragile screens, such as smart phones and tablets. In addition, the soft shock-absorbing layer can prevent the hard clamping member 5 from directly contacting the housing of the electronic device, prevent scratches or wear, and maintain the novelty of the appearance of the electronic device.

[0079] In one embodiment, an anti-slip layer is provided on the contact surface between the two clamping parts and the electronic device.

[0080] It is understood that the anti-skid layer can be made of materials with a high friction coefficient, such as rubber, silicone, special coatings or fabrics, which can significantly increase the friction of the contact surface, and keep the electronic device stable even in the bumps and shakes of the vehicle during driving. By enhancing the friction, the anti-skid layer can prevent the electronic device from sliding on the supporting device or falling in emergency braking, turning, etc., ensuring the safety of the device, while also reducing the need for the driver or passengers to adjust the device while driving, thereby improving driving safety.

[0081] It should be noted here that the above two methods can be combined and set together, and their technical effects are the same as above, so no further elaboration is made here.

[0082] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
