[0025] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Refer to the attached Figure 1 and Figure 4 This embodiment provides a portable mounting and fixing device for a vehicle-mounted speedometer, including a support base 1, which is fixed to a magnetic sticker 3 via a support arm 2. The support arm 2 and the magnetic sticker 3 are connected via a ball joint. The support arm 2 is provided with a locking assembly for locking the ball joint. After adjusting the installation angle via the ball joint, it is fixed via the locking assembly. There are multiple support arms 2 and magnetic stickers 3, which are arranged in a one-to-one correspondence to form multi-point support, which is beneficial to improving the stability of the support base 1. The mounting base 4 is fixed to the support base 1 via a spherical head 5. The mounting base 4 is provided with a plurality of mounting holes 411, which can be used to install different types of instruments. The spherical head 5 is an existing technology that adopts a ball head joint design and can flexibly adjust the angle of the mounting base 4, that is, adjust the installation angle of the instrument. The spherical head 5 is equipped with a locking device, which can quickly fix the angle by rotating the adjustment knob to ensure stability. In this utility model, the magnetic sticker 3 is directly attached to the vehicle door, making it easy to install and remove. The support base 1 forms multiple support points on the vehicle door through the support arm 2 and the magnetic sticker 3, effectively ensuring the stability of the support base 1 and preventing the instrument from shaking or tilting. The ball-jointed connection between the support and the magnetic sticker 3 can adapt to the door structure of different vehicles.

[0027] An implementation method of locking the ball joint with the locking assembly: Figure 3The support arm 2 includes a first clamping plate 21 and a second clamping plate 22. A ball socket 100 is formed between the first clamping plate 21 and the second clamping plate 22. The magnetic sticker 3 is provided with a ball 33 that cooperates with the ball socket 100. The locking screw 6 passes through the first clamping plate 21 and the second clamping plate 22 and is threadedly connected to the locking nut. The locking screw 6 and the locking nut constitute a locking assembly. Loosening the locking screw 6 expands the diameter of the ball socket 100, and the ball 33 can rotate in the ball socket 100, thereby facilitating the adjustment of the installation angle of the magnetic sticker 3. The utility model can control the clamping force by rotating the locking screw 6, thereby fixing or loosening the ball 33.

[0028] Specifically, the first clamping plate 21 and the second clamping plate 22 are both provided with grooves communicating with the ball socket 100 . When the first clamping plate 21 and the second clamping plate 22 are closed, the two grooves enclose a through hole, which helps to reduce weight.

[0029] As another embodiment of the present invention, a knob 7 is provided on the locking screw 6 , and the locking screw 6 can be rotated conveniently by the knob 7 .

[0030] As another embodiment of the present invention: a buffer layer is provided on the sphere 33. Specifically, the surface of the sphere 33 is coated with a layer of plastic (such as reinforced nylon or TPU material). This setting can not only prevent the sphere 33 from being worn, but also increase the friction of the sphere 33 to ensure that it is not easy to loosen after the angle is adjusted.

[0031] Specifically, the sphere 33 is a metal sphere with a diameter of 25 mm, thereby being able to provide a larger contact area and load-bearing capacity.

[0032] As another embodiment of the present invention, an anti-skid layer is provided inside the ball socket 100, thereby further improving the fixing effect after the ball 33 is clamped. Specifically, the inner wall of the ball socket 100 is provided with an anti-skid texture.

[0033] Specifically, the support arm 2 is made of high-strength aluminum alloy or stainless steel, which can withstand large external forces.

[0034] An embodiment of the magnetic sticker 3: Figure 7 The magnetic sticker 3 includes a magnetic plate 31, and the sphere 33 is fixed on the magnetic plate 31 through an oblique arm 32. Specifically, the oblique arm 32 is fixed on the magnetic plate 31 through a bolt.

[0035] Specifically, the magnetic plate 31 is made of a large diameter (eg, 50 mm) high-strength magnetic material (eg, a neodymium iron boron magnet) to provide a strong adsorption force.

[0036] As another embodiment of the present invention, a protective layer made of rubber is provided on the magnetic plate 31. This structural design prevents the magnetic plate 31 from directly contacting the vehicle door and scratching the paint, and also cushions collisions, protecting the magnetic plate 31 and the door surface from damage.

[0037] As another embodiment of the present invention: both the first clamping plate 21 and the second clamping plate 22 are provided with avoidance grooves adapted to the oblique arm 32 , and the avoidance grooves are distributed in a cross shape on the support arm 2 .

[0038] As another embodiment of the present invention: Figure 6 An adjustment arm 8 is fixed to the support base 1, and the adjustment arm 8 is connected to the end of the support arm 2 away from the magnetic sticker 3 through a ball joint. In this structural design, the adjustment arm 8 facilitates the adjustment of the angle between the support arm 2 and the support base 1, further expanding the adaptability to different vehicle door bodies.

[0039] As another embodiment of the present invention: the adjusting arm 8 is fixed to the supporting base 1 by screws.

[0040] An embodiment of the support base 1: Figure 2 The support base 1 includes a box body 11, and extension plates 12 are fixed on both sides of the box body 11. An adjusting arm 8 and a spherical head 5 are respectively fixed on the other two sides of the box body 11, and the other two adjusting arms 8 are fixed on the extension plates 12, that is, the spherical head 5 and three adjusting arms 8 are respectively distributed on the four sides of the box body 11.

[0041] As another embodiment of the present invention: Figure 4 and attached Figure 5 The mounting base 4 includes a mounting plate 41 and a connecting plate 42 fixed to the mounting plate 41. The connecting plate 42 is provided with a positioning pin 43 that matches the positioning slot 51 of the spherical head 5. A gasket is provided between the connecting plate 42 and the spherical head 5. The connecting plate 42 and the spherical head 5 are fixed together by screws. The gasket is a rubber gasket that can effectively reduce vibration transmission and protect the instrument.

[0042] Specifically, the mounting holes 411 are divided into two groups, and the diameters of the two groups of mounting holes 411 are different, such as M4 or M6 threaded holes. In this structural design, various instruments can be installed by fixing screws and washers.

[0043] As another embodiment of the present invention: a plurality of heat dissipation holes 412 are provided on the mounting plate 41, which can increase air circulation and improve heat dissipation efficiency, and is suitable for the installation requirements of instruments that work for a long time.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
