[0027] Furthermore, directional terms such as "up," "down," "left," "right," "top," "bottom," and "vertical" are based on the posture and position of the device or equipment described in this invention when it is in normal use.

[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be described in detail below. Of course, the described embodiments are only a part of the embodiments of the present invention, and are not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without any creative efforts all fall within the scope of protection of the present invention.

[0029] As shown in FIGS. 1 to 16, a preferred embodiment of the in-car electronic device holder of the present invention includes a holder body 10 and a mounting holder 20 that can be folded and stored on the upper rear surface of the holder body 10. When the mounting holder 20 is unfolded to a predetermined position, it forms an angle A perpendicular to the holder body 10. Naturally, the unfolded angle may be either an acute or obtuse angle. If the unfolded angle is an obtuse angle, a stop mechanism must be designed to prevent the device from slipping off. Furthermore, a positioning clamping gap 30 for clamping the steering wheel is formed between the mounting holder 20 and the upper rear surface of the holder body 10. During use, the holder body 10 is abutted against the front of the steering wheel, the mounting holder 20 is unfolded, and the positioning clamping gap 30 is hooked onto the top of the steering wheel, allowing the holder body 10 to clamp the steering wheel. This allows users to easily place a laptop or book on the holder body 10 for reading or browsing, making it highly practical.

[0030] In this embodiment, the holder body 10 is provided with a storage groove 40 for storing the folded fastening holder 20. This reduces the thickness of the holder body 10 in the front-to-rear direction after storage, making it easier to store and keep the entire holder body 10.

[0031] Furthermore, since the storage groove 40 penetrates the holder main body 10 in the front-to-rear direction, the attachment holder 20 can be stored within the holder main body, and the tight fit between the left and right side walls of the storage groove 40 and the attachment holder 20 realizes clamping and positioning of the attachment holder 20 by friction, preventing the attachment holder 20 from loosening and falling off after storage. Naturally, by making the rotation axis of the attachment holder a damper type rotation, it is also possible to prevent the attachment holder from loosening after storage.

[0032] In this embodiment, a protrusion 50 that protrudes forward is provided at the top end of the holder body 10, and a recess 51 is formed on the back of the protrusion 50, with the storage groove 40 provided in the recess. The provision of the protrusion 50 allows the fastening holder 20 to be stored further, and serves to bring the fastening holder 20 closer to the front of the holder body 10 after storage. At the same time, by moving the position of the clamping positioning gap forward, i.e., by relatively moving the holder body 10 rearward, when the holder body 10 is left in front of the steering wheel, it can abut against the side wall of the protrusion of the operation button located in the center of the steering wheel, and the holder body 10 moves sideways to avoid being over the button, thereby preventing accidental operation.

[0033] Specifically, the protrusion 50 has an L-shape with its horizontal end 501 facing backward and its vertical end 502 facing upward, with the attachment holder 20 provided on the back surface of the vertical end 502 of the protrusion 50, and the storage groove 40 extending from the vertical end 502 to the horizontal end 501 of the protrusion 50. When the attachment holder 20 is fully stored, its tip engages with the storage groove 40 located at the junction of the horizontal end 501 and the vertical end 502, further storing and concealing the attachment holder 20 and improving the integration of the holder body 10 and the attachment holder 20 after storage. Furthermore, an anti-slip sheet is provided on the front surface of the protrusion 50 to increase the friction between the laptop computer and the holder body 10 to prevent the laptop computer from slipping off.

[0034] In this embodiment, a stopper 60 is provided on the back surface of the upper end of the holder body 10, above the attachment holder 20. When the attachment holder 20 is deployed to a predetermined position, the attachment holder 20 abuts against the lower end of the stopper 60, thereby reinforcing the positioning of the attachment holder 20.

[0035] In this embodiment, a positioning groove 61 is provided at the lower end of the stopper 60 to position the attachment holder 20. When the attachment holder 20 is deployed to a predetermined position, the attachment holder 20 is locked into the positioning groove 61, which prevents the attachment holder 20 from wobbling in the left-right direction and ensures the stability of the attachment holder 20.

[0036] In this embodiment, one end of the fastening holder 20 is hingedly connected to the holder body 10 in the vertical direction by a first rotation axis located within the receiving groove 40. The fastening holder 20 is provided with an arc-shaped recess 201 that fits the arc-shaped outer edge of the steering wheel. Specifically, this arc-shaped recess 201 is located on the side facing the positioning clamping gap 30 after the fastening holder 20 is unfolded. When the fastening holder 20 is unfolded to the predetermined position, the arc-shaped recess 201 fits tightly against the upper part of the arc-shaped outer edge of the steering wheel, increasing the contact area with the arc-shaped edge of the steering wheel and preventing surface damage caused by localized excessive pressure applied to the steering wheel. The arc-shaped recess also further improves stability after the fastening holder 20 is attached, providing additional anti-slip and anti-falloff functions.

[0037] When the fastening holder 20 is completely stored, the fastening holder 20 is partially or entirely located within the storage groove 40, and its tip is stored below the positioning clamping gap 30, thereby improving the compactness of the entire structure after storage.

[0038] In this embodiment, the fastening holder 20 has a columnar shape and a ball head 202 at its tip, i.e., the end opposite to the first rotation axis of the fastening holder 20, which is coaxially integrated with the fastening holder 20. The smooth outer surface of the ball head 202 prevents sharp edges from damaging the decorative layer on the surface of the steering wheel during installation by the user, resulting in a more ergonomic and comprehensive design. Furthermore, the arc-shaped recess 201 on the fastening holder 20 is set in a circumferential ring shape, further improving the user's grip comfort when unfolding the fastening holder 20.

[0039] In this embodiment, the holder body 10 includes a bracket 11 and a support frame 12 arranged side by side at the front and rear, the upper ends of the bracket 11 and the support frame 12 being vertically hinged, and the support frame 12 is further provided with an angle adjustment assembly 70 for adjusting the forward / backward tilt angle of the lower end of the bracket 11. The protrusion 50 and the attachment holder 20 are both provided at the upper end of the bracket 11, and the support frame 12 is located below the positioning clamping gap 30. The bracket 11 is fixed by placing the support frame 12 on the front wall of the steering wheel and hooking the unfolded attachment holder 20 onto the top of the steering wheel. In this case, after placing the laptop on the bracket 11, the forward / backward tilt of the bracket 11 and the lower end of the laptop can be adjusted using the angle adjustment assembly 70, allowing the user to easily select an angle suitable for operation and viewing.

[0040] The angle adjustment assembly 70 includes a support rod 71 hingedly connected to the support frame 12 in the vertical direction, a slider 72 slidably mounted on the bracket 11, and a positioning unit 73 for positioning the height of the slider 72. Alternatively, the slider may be mounted on the support frame 12, and the support rod is hingedly connected to the bracket. Specifically, the support rod 71 is hingedly connected to the slider 72 in the vertical direction. When the slider 72 is adjusted to a desired height in the vertical direction, the slider 72 is fixed by the positioning unit 73. This allows the support rod 71, the bracket 11, and the support frame 12 to form a stable triangular structure, thereby stably supporting the laptop computer at the desired height. In practice, the connection point between the support rod 71 and the support frame 12 is located higher than the top of the slider 72, and the lower end of the support rod 71 is located lower than the upper end.

[0041] The positioning unit 73 further includes a movable member 730 hingedly connected to the slider 72 in the vertical direction, a plurality of positioning locking grooves 732 uniformly arranged on the bracket 11 corresponding to the sliding path of the slider 72, and an elastic clamping member 733 that provides a clamping force for locking one end of the movable member 730 into the positioning locking groove 732. The elastic clamping member is typically a spring, but may alternatively be a torsion spring or an elastic metal sheet. Specifically, a movable groove 721 is formed in the rear wall of the slider 72, penetrating the front-rear direction. The movable member 730 is disposed in the movable groove 721 and is rotatably connected to the slider 72 by a second rotating shaft 80. The elastic clamping member 733 is disposed above the second rotating shaft 80, with one end abutting the slider 72 and the other end abutting the movable member 730. The connection end between the support rod 71 and the slider 72 is located above the elastic clamping member 733. When mounting is complete, the upper end of the movable member 730 protrudes from the movable groove 721, and the movable member 730 and the slider 72 form a rack-ratchet mechanism that can move intermittently only upward. In the initial state, that is, when there is no need to adjust the tilt angle of the bracket 11 in the forward / backward direction, the elastic force of the elastic fastening member 733 causes the lower end of the movable member 730 to abut within the positioning locking groove 732, and the reaction force applied to the lower end of the movable member 730 is transmitted to the support rod 71 by the slider 72 via the second rotating shaft 80, thereby supporting and holding the bracket 11 at the corresponding height.

[0042] If the laptop needs to be adjusted higher, the slider 72 is slid upward. During sliding, due to the acute angle between the lower end of the movable member 730 and the bracket 11, the lower end of the movable member 730 automatically disengages from the previous positioning locking groove 732 by the elastic fastening member 733 and automatically enters the next positioning locking groove 732, making the adjustment process very simple and quick. If the laptop needs to be adjusted lower, simply push the upper end of the movable member 730 into the movable groove 721, and the lower end of the movable member 730 will move backward and disengage from the positioning locking groove 732. In this case, the slider 72 is slid downward until it reaches the desired position, and then the upper end of the movable member 730 is released, allowing the lower end of the movable member 730 to re-engage with the positioning locking groove 732, completing the positioning and support.

[0043] The slider 72 is specifically designed as a rectangular parallelepiped structure, and the movable member 730 is a rectangular plate structure, and the second rotation shaft 80 is fixedly connected to one side of the movable member 730 in parallel.

[0044] In this embodiment, guide ribs 90 are provided on both ends of the bracket 11, located on the left and right sides of the sliding path of the slider 72, and the guide ribs 90 are parallel to the movement path of the slider 72. A guide groove 91 is provided along the longitudinal direction on the opposing side walls of the two guide ribs 90, and the slider 72 is provided with a guide protrusion 722 corresponding to the guide groove 91. When the slider 72 is fully attached, the two guide ribs 90 each come into slidable contact with the slider 72. The double guide limit action of the guide protrusion 722, guide groove 91, and guide rib 90 ensures stability in the up and down sliding of the slider 72 and makes it easy for the user to perform a pressing and sliding operation, enabling a "blind pressing operation" that does not require visual observation of the entire sliding process of the slider 72.

[0045] In this embodiment, a storage groove for storing the support rod 71 is formed in the space between the two guide ribs 90. When the bracket 11 and the support frame 12 are folded and overlapped, the support frame 12 is in close contact with the two guide ribs 90 and, together with the storage groove, surrounds and forms a storage chamber 100 for storing the support rod 71 and the slider 72. This improves protection for the slider 72 and the support rod 71 after storage, prevents the support rod 71 and the slider 72 from scattering, and improves the compactness of the entire structure of the electronic device holder.

[0046] In this embodiment, both the bracket 11 and the support frame 12 are rectangular, and the length of the bracket 11 is longer than the length of the support frame 12. When fully attached, the lower end of the bracket 11 is positioned lower than the lower end of the support frame. This prevents the lower end of the support frame 12 attached to the steering wheel from being too long and interfering with the movement of the user's thighs. Extending the lower end of the bracket 11 further downwards also makes it easier for the user to adjust the distance between the laptop computer on the bracket 11 and their body.

[0047] In this embodiment, a foldable stopper member 110 for preventing the electronic device from slipping off is provided at the lower end of the front wall of the bracket 11. Specifically, the stopper member 110 has an elongated strip shape and is hingedly connected to the bracket 11 in the vertical direction by a third rotating shaft 120. To improve the integration of the stopper member 110 and the bracket 11 after attachment, the bracket 11 is provided with a movable hole 130 through which the stopper member 110 rotates, and the stopper member 110 is disposed within the movable hole 130. Both ends of the third rotating shaft 120 are fixed to the left and right side walls of the movable hole 130, respectively. After the stopper member 110 is fully unfolded, a portion of the front wall of the stopper member 110 located above the third rotating shaft 120 abuts against the front inner wall of the movable hole 130. The third rotating shaft 120 and the front inner wall of the movable hole 130 form two fixing points, allowing the stopper member 110 to be positioned vertically. As a result, when the notebook computer is placed on the front wall of the bracket 11, the stopper member 110 supports the bottom end of the notebook computer upward, preventing the notebook computer from slipping off. Also, to prevent the bottom end of the notebook computer from accidentally moving toward the user, the stopper member 110 is provided with a protruding member 111 facing the notebook computer at the end opposite the third rotation shaft 120.

[0048] In this embodiment, two holder bodies 10 are provided, one on the left and one on the right, facing each other. The in-vehicle electronic device holder described in this embodiment further includes a distance adjustment assembly 140 for adjusting the distance between the two holder bodies 10. This allows the distance between the two holder bodies 10 on the left and right to be adjusted to accommodate steering wheels of different sizes, and also serves as a storage and folding mechanism, allowing the user to fold and store the two holder bodies 10 when not in use.

[0049] Specifically, the distance adjustment assembly 140 is a diamond-shaped telescopic frame and includes four link rods 141 corresponding to the four sides of the diamond. The intersections of the four sides of the diamond corresponding to the four link rods 141 are hingedly connected by fourth rotation shafts 142. When installed, one pair of diagonal corners of the diamond-shaped telescopic frame is arranged parallel to the bracket 11, and two sides corresponding to the other pair of diagonal corners extend to form end portions 143. These four end portions 143 are formed by adjacent sides of the diamond-shaped telescopic frame extending coaxially. Furthermore, the two upper end portions 143 on the left and right ends of the diamond-shaped telescopic frame are hingedly connected to the two brackets 11 in the vertical direction by hinge connection shafts. The two lower end portions 143 are slidably connected to the two left and right brackets 11 in the vertical direction. As a result, when the two lower end portions 143 slide upward, the diamond-shaped telescopic frame extends in the horizontal direction, increasing the distance between the two brackets 11. On the other hand, when the two lower ends 143 move downward, the diamond-shaped structure in the center of the diamond-shaped telescopic frame extends in the vertical direction while converging toward the center, making it possible to reduce the distance between the two left and right brackets 11.

[0050] It should be understood that those skilled in the art may make improvements or modifications based on the above description, and all such improvements and modifications fall within the scope of the utility model claims of the present invention.
