Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a shell and a vehicle. BACKGROUND

[0002] With the development of automobile intelligence, the vehicle-mounted Ethernet gateway gradually extends from high-end vehicles to medium and low-end vehicles, and from high-end versions to low-end or standard versions. In order to meet market demand, the price of the Ethernet gateway needs to be reduced as a whole, especially in the cost optimization of the structural design. The traditional Ethernet gateway shell usually uses two iron inserts embedded in the inside to fix the screws, but these iron inserts and their processing costs are relatively high, accounting for a large proportion of the total cost. If the iron inserts are directly cancelled, the screws will be easily loose or even fall off in the vibration environment, thereby affecting the stability and reliability of the equipment, and also possibly causing damage to the internal components of the equipment, increasing the maintenance cost. How to realize the effective anti-loosening of the Ethernet gateway shell without increasing the cost has become a technical problem to be solved. CONTENT OF THE UTILITY MODEL

[0041] The following refers to Figures 1-5 The shell 100 according to the embodiments of the present application and the vehicle are described.

[0042] As Figure 1 shown, the shell 100 according to the first aspect of the embodiments of the present application, the shell 100 comprises: a shell body 10 and an anti-loosening structure 30.

[0043] Wherein, the shell body 10 is configured as a plastic part, and the shell body 10 is provided with a mounting lug 20 on the peripheral side, the mounting lug 20 is formed with a mounting hole 20a, and a fastener 200 is threaded through the mounting hole 20a to fix the shell 100 to the vehicle body; the anti-loosening structure 30 is formed on the mounting lug 20 and is arranged around the mounting hole 20a, and the anti-loosening structure 30 is located between the fastener 200 and the mounting lug 20; the anti-loosening structure 30 comprises: a plurality of stepped portions 31, the plurality of stepped portions 31 are arranged in sequence along the peripheral projection contour of the mounting hole 20a, and each stepped portion 31 gradually increases in height in the tightening direction of the fastener 200.

[0044] Specifically, the shell body 10 can be formed with a receiving cavity for accommodating working components such as electronic elements (e.g. chips, controllers, etc.), the shell body 10 can provide mounting positions for these working components and play a good supporting, fixing and protecting role, etc. to ensure the normal operation of the working components. The shell body 10 is made of plastic material, which is beneficial to the lightweight and cost optimization of the shell 100, and can also ensure that the shell 100 has sufficient mechanical strength and corrosion resistance, which is beneficial to improve the reliability and service life of the shell 100. The circumferential side of the shell body 10 can be provided with a plurality of mounting ears 20 extending away from the shell body 10, mounting holes 20a are formed on the mounting ears 20, so that fasteners 200 (such as screws, bolts, etc.) can be arranged therein, thereby realizing the stable connection between the shell 100 and the vehicle body; the anti-loose structure 30 is formed on the mounting ear 20 and arranged around the mounting hole 20a, and the anti-loose structure 30 is located between the fastener 200 and the mounting ear 20, so as to prevent the fastener 200 from loosening. The anti-loose structure 30 includes a plurality of step portions 31 arranged in sequence in the outer peripheral projection profile of the mounting hole 20a, and the height of each step portion 31 gradually increases in the tightening direction of the fastener 200, wherein the tightening direction is the direction in which the fastener 200 is rotated and gradually tightened and fixed to the preset position during the mounting process. For example, if the threaded structure on the fastener 200 is a right-handed thread, the corresponding tightening direction is the clockwise direction, and the height of each step portion 31 gradually increases in the clockwise direction. If the threaded structure on the fastener 200 is a left-handed thread, the corresponding tightening direction is the counterclockwise direction, and the height of each step portion 31 gradually increases in the counterclockwise direction.

[0045] It should be noted that the working principle of the anti-loose structure 30 is based on the mechanical properties during the tightening process of the fastener 200. During the process of the fastener 200 penetrating the mounting hole 20a and being tightened, the head of the fastener 200 will be in contact with the step portion 31 and generate a friction force as it is tightened, and the height of the step portion 31 gradually increases in the tightening direction. Therefore, the head of the fastener 200 needs to overcome the gradually increasing friction force to continue to be tightened, and when the fastener 200 is completely tightened, the existence of the friction force can prevent the fastener 200 from loosening under the action of vibration or external force, thereby effectively improving the reliability and stability of the shell 100.

[0046] According to the shell 100 of the present application, the anti-loosening performance of the fastener 200 can be improved by the anti-loosening structure 30, so that the shell 100 can maintain good connection reliability and stability with the vehicle body during long-term use, and the durability and safety of the shell 100 and related equipment can be effectively improved. In the related art, anti-loosening is achieved by iron inserts, which requires additional metal inserts and complex processing technology, resulting in high cost. The anti-loosening structure 30 in the present application can be directly formed on the plastic shell body 10, without the need for additional metal inserts, thereby greatly reducing material and processing costs, and facilitating the lightweight of the shell 100. At the same time, the anti-loosening structure 30 can be realized by a mold forming process, which is suitable for mass production, thereby further saving the cost of a single piece and effectively optimizing the cost.

[0047] In addition, in some embodiments of the present application, the shell body 10 is configured as a cuboid structure, and the mounting ears 20 are configured to be arranged on the opposite sides of the shell body 10 in the length direction. By symmetrically arranging the mounting ears 20 on the two sides of the shell body 10 in the length direction, the shell 100 can have good installation stability and stress uniformity, and the installation process can be simplified, facilitating quick installation and disassembly and maintenance of the shell 100.

[0048] In some embodiments of the present application, the side surface of the shell body 10 is provided with a first reinforcing rib 40, and the projection of the first reinforcing rib 40 in the height direction of the shell body 10 is located within the projection range of the mounting ear 20 in the height direction of the shell body 10. The first reinforcing rib 40 can be linear, curved or grid-shaped structure, and the first reinforcing rib 40 can be configured to extend in the height direction of the shell body 10 or extend horizontally to provide good structural support. The first reinforcing rib 40 can enhance the structural strength and rigidity of the shell body 10, and improve the stress transmission and dispersion capability of the connection area between the shell body 10 and the mounting ear 20, which is beneficial to improve the structural stability of the entire shell 100.

[0049] In some embodiments, a second reinforcing rib 50 is provided between the surfaces of the mounting ear 20 and the shell body 10 facing each other. The second reinforcing rib 50 can improve the structural strength of the connection area between the mounting ear 20 and the shell body 10, and can also play a role in dispersing stress, which can improve the stress bearing capacity and impact resistance of the mounting ear 20, and further increase the anti-vibration performance of the shell 100.

[0050] Furthermore, in some embodiments, the second reinforcing rib 50 includes a first reinforcing portion 51 and a second reinforcing portion 52. The first reinforcing portion 51 is disposed between the end face of the mounting ear 20 and the side surface of the shell body 10, and the second reinforcing portion 52 is disposed between the side surface of the mounting ear 20 and the side surface of the shell body 10. The first reinforcing portion 51 extends along the edge of the end face of the mounting ear 20 to the side surface of the shell body 10, and can bear and share the stress perpendicular to the end face of the mounting ear 20, thereby improving the stability and durability of the mounting ear 20. The second reinforcing portion 52 extends along the edge of the side surface of the mounting ear 20 to the side surface of the shell body 10, and can enhance the strength of the side surface of the mounting ear 20, thereby further improving the stability and durability of the mounting ear 20. The first reinforcing portion 51 and the second reinforcing portion 52 are respectively disposed in different positions, which can achieve uniform stress distribution. In this way, the connection strength between the mounting ear 20 and the shell body 10 can be enhanced, and the reliability of the mounting ear 20 and the shell body 10 under complex working conditions (such as vibration or impact) can be effectively improved.

[0051] like Figure 4 and Figure 5 As shown, according to some embodiments of this application, the inner diameter of the anti-loosening structure 30 is greater than or equal to the inner diameter of the cylindrical segment of the mounting hole 20a.

[0052] Specifically, the inner diameter of the anti-loosening structure 30 can be understood as the diameter of the contour defined by the multiple stepped portions 31 on the radially opposite side. The cylindrical segment of the mounting hole 20a refers to the portion of the mounting hole 20a corresponding to the arc-shaped contour in the outer peripheral projection contour of the mounting hole 20a. For example, when the mounting hole 20a is a circular hole, the outer peripheral projection contour of the mounting hole 20a is circular, and the cylindrical segment of the mounting hole 20a refers to the entire mounting hole 20a. When the mounting hole 20a is an oblong hole, etc., the outer peripheral projection contour of the mounting hole 20a includes a straight contour and an arc contour, then the portion of the mounting hole 20a corresponding to the arc contour is the cylindrical segment of the mounting hole 20a. In this embodiment, by setting the inner diameter of the anti-loosening structure 30 to be greater than or equal to the inner diameter of the cylindrical section of the mounting hole 20a, the inner diameter of the anti-loosening structure 30 is made reasonable. While ensuring the anti-loosening function, it can ensure that there is no interference between the inner side of the anti-loosening structure 30 (i.e., the side of the anti-loosening structure 30 that is radially closer to the mounting hole 20a) and the fastener 200 that passes through the mounting hole 20a. This ensures that the fastener 200 can pass smoothly through the mounting hole 20a and achieve an effective fixing function.

[0053] Furthermore, in some specific embodiments of this application, the inner diameter of the anti-loosening structure 30 is set to 8 mm to adapt to the mounting hole 20a and the fastener 200.

[0054] like Figure 1 As shown, according to some embodiments of this application, the center angle of each step portion 31 of the cylindrical segment corresponding to the mounting hole 20a is 10° to 30°.

[0055] Specifically, the smaller the central angle of each step portion 31, the greater the total number of step portions 31 on the outer periphery of the mounting hole 20a, and the more densely the step portions 31 are arranged. Conversely, the greater the central angle of each step portion 31, the fewer the total number of step portions 31 on the outer periphery of the mounting hole 20a, and the more sparsely the step portions 31 are arranged. When the central angle of each step portion 31 is less than 10°, such as 2° or 5°, the central angle is too small, causing the step portions 31 arranged along the outer periphery of the mounting hole 20a to be too dense, which increases the complexity of mold forming and makes it difficult to manufacture. When the central angle of each step portion 31 is greater than 30°, such as 60° or 90°, the central angle is too small, causing the step portions 31 arranged along the outer periphery of the mounting hole 20a to be too sparse, which reduces the anti-loosening effect and causes the fastener 200 to be easily loosened or detached in a vibrating environment, thereby affecting the installation and fixation of the shell 100. In the embodiments of the present application, the central angle of each step portion 31 of the cylindrical segment corresponding to the mounting hole 20a is set to be within the range of 10°-30°, such as 10°, 15°, or 30°, so that the arrangement density of the step portions 31 is reasonable, and the anti-loosening effect can be ensured while the feasibility of the manufacturing process is taken into account, thereby saving production costs.

[0056] In addition, in some specific embodiments of the present application, the mounting hole 20a is configured as a circular hole, the central angle of each step portion 31 is configured as 15°, and the total number of step portions 31 corresponding to a single mounting hole 20a is 24, to ensure good anti-loosening effect and take into account the convenience of the manufacturing process.

[0057] As shown in FIG. 1, according to some embodiments of the present application, the mounting hole 20a includes a cylindrical segment and a straight segment, and the regions corresponding to the cylindrical segment and the straight segment are both provided with step portions 31. Figures 1-5 Specifically, the mounting hole 20a includes a cylindrical segment and a straight segment, the projection profile of the cylindrical segment is arc-shaped, and the projection profile of the straight segment is a straight line or a shape composed of multiple straight lines. The regions corresponding to the cylindrical segment and the straight segment are both provided with step portions 31 to form full-range coverage of the side of the end face of the mounting hole 20a, to ensure that the fastener 200 can be subjected to the resistance action of the step portions 31 during the tightening process. In this way, the anti-loosening effect of the fastener 200 can be further enhanced, and the stability and reliability of the shell 100 in various complex environments can be further improved, to provide reliable protection for the normal operation of the equipment.

[0058]

[0059] ​In addition, by arranging the step portion 31 on both the cylindrical segment and the straight segment, the anti-loosening structure 30 can be applied to different mounting holes 20a, thereby facilitating the adaptation to fasteners 200 of different shapes and sizes, and improving the compatibility and versatility of the shell 100, especially the adaptability to fasteners 200 of special shapes, such as flat head screws or self-tapping screws.

[0060] As shown in Figures 1-5 According to some embodiments of the present application, the width dimension of each step portion 31 corresponding to the straight segment of the mounting hole 20a is the maximum width dimension of the step portion 31 corresponding to the cylindrical segment.

[0061] Specifically, the width dimension of the step portion 31 corresponding to the cylindrical segment of the mounting hole 20a can be understood as the dimension of the step portion 31 corresponding to the cylindrical segment in the circumferential direction, and the maximum width dimension of the step portion 31 corresponding to the cylindrical segment refers to the maximum dimension of the step portion 31 corresponding to the cylindrical segment in the circumferential direction. The width dimension of the step portion 31 corresponding to the straight segment of the mounting hole 20a can be understood as the dimension of the step portion 31 corresponding to the straight segment of the mounting hole 20a in the arrangement direction of the step portions 31 corresponding to the straight segment of the mounting hole 20a. In the embodiments of the present application, the width dimension of each step portion 31 corresponding to the straight segment of the mounting hole 20a is the maximum width dimension of the step portion 31 corresponding to the cylindrical segment, which can improve the uniformity of the width dimension of the step portion 31 corresponding to the straight segment of the mounting hole 20a and the step portion 31 corresponding to the cylindrical segment, and improve the uniformity of the arrangement of the anti-loosening structure 30 in the mounting hole 20a. In this way, it is helpful to make the fastener 200 receive uniform resistance during tightening, so as to achieve reliable and uniform anti-loosening effect.

[0062] As shown in Figure 4 and Figure 5 According to some embodiments of the present application, the outer diameter of the anti-loosening structure 30 is less than or equal to the equivalent circle outer diameter of the limiting end 201 of the fastener 200.

[0063] Specifically, when the outer diameter of the anti-loosening structure 30 is greater than the equivalent circle outer diameter of the limiting end 201 of the fastener 200, it is easy to cause the fastener 200 to produce a sub-mark after being tightened, forming an appearance defect, and affecting the service life and connection reliability of the part. In the embodiments of the present application, the outer diameter of the anti-loosening structure 30 is set to be less than or equal to the equivalent circle outer diameter of the limiting end 201 of the fastener 200. The outer diameter of the anti-loosening structure 30 can be the same as the equivalent circle outer diameter of the limiting end 201 (i.e. the head of the fastener 200), or slightly smaller than the equivalent circle outer diameter of the limiting end 201 (i.e. the head of the fastener 200), which can ensure the appearance integrity of the fastener 200 and the anti-loosening structure 30, and achieve good anti-loosening effect.

[0064] In addition, in some embodiments of the present application, the outer diameter of the anti-loosening structure 30 is set to 14 mm to be well adapted to contact the fastener 200.

[0065] As shown in Figure 4 and Figure 5 According to some embodiments of the present application, the limiting end 201 is adapted to be provided with a limiting structure matched with the anti-loosening structure 30 on one side surface of the anti-loosening structure 30.

[0066] Specifically, the limiting end 201 of the fastener 200 can be provided with a limiting structure on one side surface of the anti-loosening structure 30 in the thickness direction, and the limiting structure can be mechanically matched (such as embedded, buckled, etc.) with the anti-loosening structure 30 to increase the friction and resistance of the fastener 200 in the tightening direction, so as to enhance the anti-loosening effect. The limiting structure can be a groove, a protrusion, an inclined surface or other shaped structure. Exemplarily, the limiting structure is configured as a groove, and the stepped portion 31 of the anti-loosening structure 30 can be embedded with the groove of the limiting end 201 to enhance the contact and engagement effect between the anti-loosening structure 30 and the limiting end 201, so as to provide additional anti-loosening effect after the fastener 200 is tightened, improve the position stability of the fastener 200 after being tightened, and further improve the anti-vibration performance and stability of the shell 100.

[0067] As shown in Figure 2 and Figure 3 According to some embodiments of the present application, the highest point of the stepped portion 31 has a height h, and satisfies: 0.3 mm≤h≤0.7 mm.

[0068] Specifically, the highest point of the stepped portion 31 can be understood as the maximum vertical distance of the stepped portion 31 relative to the reference surface of the mounting hole 20a. When the highest point of the stepped portion 31 has a height h less than 0.3 mm, such as h being 0.2 mm or 0.1 mm, etc., the height of the stepped portion 31 is too low, on one hand, which will make the resistance of the stepped portion 31 to the fastener 200 too small, weaken the anti-loosening effect, and the fastener 200 is prone to loosening in the vibration or impact environment, so as to fail to effectively prevent the connection failure caused by external force; on the other hand, the height of the stepped portion 31 is too low, which also makes the precision requirement of the mold forming higher, which will lead to increased difficulty in mold processing, and bring the risk of material shortage and poor collapse forming. When the highest point of the stepped portion 31 has a height h greater than 0.7 mm, such as h being 1 mm or 1.5 mm, etc., the height of the stepped portion 31 is too high, which will reduce its own structural strength, cause local stress concentration, and result in damage or deformation of the stepped portion 31, thereby reducing the reliability of the anti-loosening structure 30. In addition, the height of the stepped portion 31 is too high, which will also make the friction and resistance that the fastener 200 needs to overcome during tightening too large, so as to require a larger torque to complete the tightening operation in the assembly process, thereby increasing the assembly difficulty, and possibly causing damage to the fastener 200 or the shell 100.

[0069] In the embodiments of the present application, the height h of the highest point of the step portion 31 is set in the range of 0.3mm to 0.7mm, such as 0.3mm, 0.4mm or 0.7mm, so that the height of the step portion 31 is controlled in a reasonable range, so that the step portion 31 can provide appropriate resistance during the tightening of the fastener 200, so as to effectively prevent loosening caused by vibration or impact, at the same time, the step portion 31 itself has good structural strength, which ensures the reliability of the anti-loosening structure 30, and the height of the step portion 31 will not interfere with the assembly process of the fastener 200, which can ensure the assembly convenience of the fastener 200.

[0070] In addition, in some specific embodiments of the present application, the height of the highest point of the step portion 31 is 0.5mm, so as to realize that the step portion 31 has good structural strength and ensures that the step portion 31 has good anti-loosening effect on the fastener 200.

[0071] As shown in Figures 1-5 According to some embodiments of the present application, the shell 100 is configured as the shell of the vehicle-mounted gateway.

[0072] Specifically, the vehicle-mounted gateway is a key device for internal network communication of the vehicle, and contains a plurality of key electronic components and communication modules inside, and the shell of the vehicle-mounted gateway needs to protect these internal components from interference and damage from the outside environment. The vehicle-mounted gateway usually needs to operate stably under complex working conditions such as vibration, impact and temperature change.
