[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features.

[0029] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] See Figure 1 and Figure 2 An embodiment of the present application provides a display device, including a backlight module and a control component. The backlight module and the control component are connected. Specifically, the backlight module and the control component are electrically connected. The control component is used to provide electrical energy to the backlight module and can control the backlight module switch, light source color or brightness.

[0032] See again Figure 2 The above-mentioned backlight module includes a first fixing member 1, a light guide plate 2 and a light-emitting member 3. The first fixing member 1 is provided with an installation space 11; the light guide plate 2 is located in the installation space 11 and is spaced apart from the side wall of the first fixing member 1; the light-emitting member 3 is connected to the side wall of the first fixing member 1 and is spaced apart from the light guide plate 2; wherein, the light guide plate 2 has a light-incoming side 21, the light-incoming side 21 faces the light-emitting surface of the light-emitting member 3, and an abutment member 22 is provided between the light-incoming side 21 and the side wall of the first fixing member 1, and the abutment member 22 abuts against the light guide plate 2 and the side wall of the first fixing member 1 or the lamp board of the light-emitting member 3 respectively.

[0033] In actual application, the first fixing member 1 is mainly used to fix the light-emitting member 3 and provide a position for installing the light guide plate 2. The first fixing member 1 is provided with an installation space 11. The side wall of the first fixing member 1 is connected to the light-emitting member 3. The light-emitting surface of the light-emitting member 3 faces the light guide plate 2. The light guide plate 2 is arranged in the installation space 11, and its light-incoming side 21 faces the light-emitting surface of the light-emitting member 3. An abutment member 22 can be provided between the light-incoming side 21 and the side wall of the first fixing member 1. The abutment member 22 abuts the light guide plate 2 and the first fixing member 1 respectively. When the light guide plate 2 shakes, the abutment member 22 limits the light guide plate 2 from moving in a direction close to the light-emitting member 3 to avoid the light guide plate 2 colliding with the light-emitting member 3 when subjected to external force, thereby avoiding damage to the light-emitting member 3 when the backlight module is used in a vibrating or shaking scenario.

[0034] It should be noted that the light-emitting component 3 usually includes a lamp board and lamp beads, the lamp beads are connected to the lamp board, and then the lamp board is fixed to the side wall of the first fixing component 1 to achieve the installation and fixation of the light-emitting component 3; the side where the lamp beads are located is the light-emitting surface of the light-emitting component 3, so the abutment 22 can also be arranged between the lamp board and the light guide plate 2, and the abutment 22 abuts the lamp board and the light guide plate 2 respectively. This arrangement can also prevent the light guide plate 2 from colliding with the light-emitting component 3.

[0035] Compared to the prior art, this application provides an abutment member 22 between the light guide plate 2 and the light-emitting element 3. This abutment member 22 is used to prevent the light guide plate 2 from impacting the light-emitting element 3 when shaking or vibrating, thereby ensuring that the light-emitting element 3 is not squeezed and damaged, making the backlight module suitable for sports scenes. A display device using this backlight module meets the needs of various scenarios, extends the service life of the display device, and improves the practicality and cost-effectiveness of the device.

[0036] See Figure 3 and Figure 4 The two ends of the light-inlet side 21 can extend toward the side wall of the first fixing member 1 to form abutment members 22 , and a lamp groove 23 is formed between the two abutment members 22 on the same side of the light-inlet side 21 , and the light-emitting member 3 is located in the lamp groove 23 .

[0037] In practical applications, the abutment member 22 can be integrally formed with the light guide plate 2. Specifically, both ends of the light-inlet side 21 extend toward the light-emitting member 3 until they abut against the first fixing member 1, thereby forming a boss structure. The boss structure can serve as the abutment member 22 to protect the light-emitting member 3 from being squeezed and impacted by the light guide plate 2. The use of an integrally formed structure can reduce the number of steps required to install the abutment member 22, thereby improving production efficiency and reducing production costs. Furthermore, abutment members 22 are provided at both ends, and the light-emitting member 3 is located between the lamp trough 23 formed by the two abutment members 22, further protecting the light-emitting member 3 and enhancing the abutment effect.

[0038] In one embodiment, both ends of the first fixing member 1 may also extend toward the light-entering side 21 to form abutment members 22 , and a lamp groove 23 is formed between the two abutment members 22 on the same side of the first fixing member 1 , and the light-emitting member 3 is located in the lamp groove 23 .

[0039] In practical applications, the abutment member 22 can also be integrally formed with the first fixing member 1 , with both ends of the first fixing member 1 extending toward the light-entry side 21 until they abut against the light guide plate 2 to form a boss structure to achieve the abutment function.

[0040] It should be noted that the abutment member 22 can also adopt a separate structure from the light guide plate 2 or the first fixing member 1. For example, the abutment member 22 can be a block structure and inserted between the first fixing member 1 and the light guide plate 2. This application does not limit this.

[0041] See again Figure 4 The distance between the light-emitting surface of the light-emitting element 3 and the light-incoming side 21 is between 0.15 mm and 0.25 mm.

[0042] In actual applications, the light-emitting component 3 usually includes a lamp board and lamp beads. The lamp beads are connected to the lamp board. The side where the lamp beads are located is the light-emitting surface of the light-emitting component 3. A gap is left between the lamp beads and the light-incoming side 21. This gap can be 0.15mm, 0.2mm or 0.25mm. This ensures that when the backlight module is impacted by a large external force or the abutment 22 is deformed, the light guide plate 2 moves or deforms to a certain extent and still does not hit the lamp beads of the light-emitting component 3, thereby avoiding damage to the lamp beads, improving the safety of the structure, and adapting to more usage scenarios.

[0043] See again Figure 3 The backlight module further includes a buffer member 5 . One side wall of the first fixing member 1 is connected to the light emitting member 3 , and the buffer member 5 is abutted between the remaining side walls and the light guide plate 2 .

[0044] In actual applications, the buffer member 5 mainly plays the role of squeezing and fixing the light guide plate 2. At the same time, it can prevent the light guide plate 2 from colliding with the first fixing member 1 under impact, protect the light guide plate 2, and reduce impact damage. The buffer member 5 has a certain elasticity and deformability, and can be adjusted according to the shape and size of the light guide plate 2 to achieve a tighter fit and more stable fixation.

[0045] It should be noted that the first fixing member 1 can be polygonal in shape, and the first fixing member 1 can be provided with a light-emitting member 3 on one of its side walls, or the first fixing member 1 can be provided with light-emitting members 3 on multiple side walls. Preferably, the number of side walls of the first fixing member 1 on which the light-emitting members 3 are provided is less than or equal to the number of side walls on which the buffer members 5 are provided, or the light-emitting members 3 and the buffer members 5 can be provided on the opposite side walls of the first fixing member 1, respectively.

[0046] In other embodiments, the first fixing member 1 may also adopt other shapes, such as an arc or a circle. In this case, at least a portion of the side wall of the first fixing member 1 is connected to the light-emitting member 3, and abutment members 22 are provided at both ends of the light-emitting member 3 to facilitate the positioning of the light-emitting member 3 within the lamp groove 23, thereby effectively preventing the light guide plate 2 from colliding with the light-emitting member 3. It is understood that the specific shape of the first fixing member 1 is determined according to actual production requirements and is not limited in this application.

[0047] In one embodiment, the compression amount of the buffer 5 is greater than 50%.

[0048] In practical applications, compression of the buffer 5 can better absorb impact forces. When the buffer 5 is compressed, its internal structure deforms, converting the external impact force into its own elastic potential energy, thereby effectively absorbing and dissipating the impact force. The compressed buffer 5 can also improve the fixing stability. The compression amount of the buffer 5 can be set to a value such as 55% or 60%.

[0049] In one embodiment, the buffer member 5 can be interference fit with the light guide plate 2, and the interference is 0.2mm~0.25mm. For example, the interference is set to 0.2mm or 0.22mm, etc., which can also play the role of the above-mentioned buffer member 5 being compressed.

[0050] An interference fit is a mechanical assembly method. After assembly, a compressive force exists between the light guide plate 2 and the buffer 5, tightly binding them together and improving the fixation stability of the light guide plate 2. It should be noted that interference fit generally refers to the relationship between the tolerance zones of a hole and a shaft of substantially the same size. In this embodiment, interference fit can refer to the compressed length of the buffer 5.

[0051] It is understandable that the buffer member 5 can be made of elastic material, such as silicone.

[0052] See Figure 5 、 Figure 6 and Figure 7 The backlight module also includes a second fixing member 4, which is connected to the first fixing member 1 and axially abuts the light guide plate 2; the second fixing member 4 is provided with a fixing groove 41, and the outer wall of the first fixing member 1 is provided with a fixing portion 12, which is inserted into the fixing groove 41.

[0053] In actual use, the second fixing member 4 and the first fixing member 1 are connected together to form a closed installation space 11, which provides a location for installing the light guide plate 2 and the light-emitting element 3, preventing external impurities from entering the installation space 11 and contaminating the light guide plate 2 and the light-emitting element 3. In addition, the second fixing member 4 at least partially extends into the installation space 11 to facilitate axial positioning of the light guide plate 2, further improving the stability of the installation of the light guide plate 2.

[0054] It is understood that the second fixing member 4 and the first fixing member 1 can be connected in an inserting manner. For example, the second fixing member 4 has multiple fixing grooves 41 on the outside, and the first fixing member 1 has multiple fixing portions 12 on the outside; or the second fixing member 4 has multiple fixing portions 12 on the inside, and the first fixing member 1 has multiple fixing grooves 41 on the outside, and the fixing portions 12 are inserted into the fixing grooves 41 to complete the fixed connection between the first fixing member 1 and the second fixing member 4. In other embodiments, the first fixing member 1 and the second fixing member 4 can also adopt other connection methods, which are not limited in this application.

[0055] See Figure 8 An elastic arm 13 is provided on the outer side wall of the first fixing member 1 , and the elastic arm 13 abuts against the inner side wall of the second fixing member 4 .

[0056] The elastic arm 13 can be elastically deformed during the installation process of the first fixing member 1 and the second fixing member 4, so that the second fixing member 4 can be sleeved on the outer periphery of the first fixing member 1 and the fixing portion 12 can be inserted into the fixing groove 41. The provision of the elastic arm 13 can improve the convenience of installation of the first fixing member 1 and the second fixing member 4, and facilitate the installation and disassembly of the first fixing member 1 and the second fixing member 4.

[0057] See again Figure 6 The backlight module also includes a third fixing member 6 and a display component 7. The display component 7 is arranged on the side of the second fixing member 4 away from the light guide plate 2. The second fixing member 4 is provided with a step portion 42. The display component 7 is overlapped on the step portion 42. The third fixing member 6 is connected to the outer side of the second fixing member 4 and abuts against the display component 7.

[0058] In actual application, the display component 7 is mainly used to display images, and the third fixing member 6 is used to fix the display component 7. Specifically, the second fixing member 4 is provided with a step portion 42 on the side facing away from the light guide plate 2, and the display component 7 is overlapped on the step portion 42. The third fixing member 6 is connected to the outer side of the second fixing member 4 and at least partially extends in the direction close to the display component 7, so as to limit the display component 7 axially together with the step portion 42 to avoid displacement of the display component 7 and relative movement between the display component 7 and the light guide plate 2, thereby affecting the display function.

[0059] It should be noted that the third fixing member 6 and the second fixing member 4 can be connected in a detachable manner. For example, the second fixing member 4 can be provided with multiple snap-in parts along the outer side, and the third fixing member 6 has multiple snap-in grooves along its outer side, or the second fixing member 4 has multiple snap-in grooves along the outer side, and the third fixing member 6 has multiple snap-in parts along its outer side, and the snap-in parts and the snap-in grooves are snapped together to realize the connection between the second fixing member 4 and the third fixing member 6.

[0060] It is understandable that in some other embodiments, the second fixing member 4 and the third fixing member 6 may also be connected in different ways, which is not limited in this application.

[0061] In one embodiment, the first fixing member 1 and the third fixing member 6 can be made of metal. Metal has high strength and rigidity and is not easily deformed during daily use. Metal is also thin, making the entire display device housing thin, more refined and beautiful. Metal also has good heat dissipation properties, which helps to reduce the operating temperature of the display device and improve its stability and lifespan.

[0062] The second fixing member 4 can be made of plastic. The second fixing member 4 is fixed between the first fixing member 1 and the third fixing member 6 and is located inside the display device. There are many electrical components inside the display device. The second fixing member 4 made of plastic can play a role in protection and shock absorption, and has good insulation and moisture-proof properties, protecting the internal light guide plate 2 or the light-emitting component 3 from moisture, ensuring that the display device can work normally in various environments.

[0063] Different from the prior art, the embodiments of the present application provide a backlight module and a display device. The backlight module includes a first fixing member 1, a light guide plate 2, and a light-emitting member 3. The first fixing member 1 is provided with an installation space 11. The light guide plate 2 is located in the installation space 11 and is spaced apart from the side wall of the first fixing member 1. The light-emitting member 3 is connected to the side wall of the first fixing member 1 and is spaced apart from the light guide plate 2. The light guide plate 2 has a light-inlet side 21, which faces the light-emitting surface of the light-emitting member 3. An abutment member 22 is provided between the light-inlet side 21 and the side wall of the first fixing member 1. The abutment member 22 abuts against the light guide plate 2 and the side wall of the first fixing member 1, or the light panel of the light-emitting member 3, respectively. The present application provides an abutment member 22 between the light guide plate 2 and the light-emitting member 3. The abutment member 22 is used to prevent the light guide plate 2 from impacting the light-emitting member 3 when shaking or vibrating, thereby ensuring that the light-emitting member 3 is not squeezed and damaged, making the backlight module suitable for sports scenes. A display device using this backlight module can meet the needs of various scenarios, extend the service life of the display device, and improve the practicality and economy of the device.

[0064] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
