Description

Technical Field

[0001] The present invention relates to a controller, in particular to a vehicle body controller. Background Art

[0002] Body controllers are used in automobiles and function not only to communicate with vehicle systems via CAN but also to control vehicle pumping. Conventional body controllers typically include a housing, a circuit board housed within the housing, and a light guide. The circuit board is equipped with a light source, which emits light that is directed through the light guide to provide reminders and warnings. Currently, there are two main methods for securing the light guide in body controllers: one is to insert the light guide from the top of the housing and then secure it with glue; the other is to insert the light guide from the bottom up and secure it with a clip inside the housing. However, the glue-sealing method has the following drawbacks: the glue takes time to cure, resulting in low assembly efficiency. In particular, the glue is prone to aging and falling off, resulting in a loose hold on the light guide. The clip-on method also has the following drawbacks: the clip primarily serves as a lateral limiter for the light guide and cannot provide axial positional control. Therefore, an additional axial limiter structure is required on the housing, making it inconvenient to manufacture and costly. Summary of the Invention

[0003] In view of the technical problems existing in the prior art, the present invention provides a vehicle body controller, which can not only improve the assembly efficiency of the light guide column, but also simplify the structure of the housing.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a car body controller, including a shell, a circuit board and a light guide column, the circuit board is located in the shell, and a light source is arranged on the circuit board, and the shell is provided with a through hole corresponding to the light guide column; the light guide column includes a support and a column arranged on the support, and a hollow positioning column corresponding to the through hole is provided in the shell, the column of the light guide column is sequentially passed through the positioning column and the through hole, and the end of the positioning column facing away from the through hole abuts the support, the support abuts the circuit board, and the light source corresponds to the support.

[0005] Furthermore, a recessed groove corresponding to and communicating with the through hole is provided on the outer surface of the shell at the through hole, and one end of the column facing away from the support enters the recessed groove.

[0006] Furthermore, the end of the column facing away from the support does not protrude from the outer surface of the shell where the through hole is located.

[0007] Furthermore, the support is provided with an accommodation portion, and the light source enters the accommodation portion; the accommodation portion of the support is an accommodation groove provided at one end of the support facing the circuit board.

[0008] Furthermore, the side surface of the support is provided with at least one accommodating notch leading to the accommodating groove. The cross-sectional shape of the column is flat, and the cross-sectional shape of the positioning column and the shape of the through hole are adapted to the cross-sectional shape of the column.

[0009] Furthermore, the cross-section of the column is elliptical.

[0010] Furthermore, the cross-sectional dimension of the column gradually decreases from the end of the column connected to the support toward the end of the column away from the support.

[0011] Furthermore, the outer circumference of the positioning column is provided with a reinforcement structure connected to the inner wall of the shell; the reinforcement structure includes a plurality of reinforcement members distributed on the outer circumference of the positioning column at intervals along the circumference of the positioning column, each reinforcement member is a reinforcement rib or a reinforcement plate, and is respectively located in the length direction of the positioning column.

[0012] Furthermore, the shell includes an upper shell and a lower shell, which are connected up and down to form a shell cavity, and the circuit board is located in the shell cavity; the through hole and the positioning column are arranged on the top wall of the upper shell.

[0013] Furthermore, the light source is an LED light source, and the LED light source is a multi-color LED.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Since the light guide column includes a support and a column disposed on the support, a hollow positioning column corresponding to the through hole is provided in the shell, and the column of the light guide column is sequentially passed through the positioning column and the through hole, and the end of the positioning column facing away from the through hole abuts against the support, and the support abuts against the circuit board. The light source corresponds to the support, so that the invention can use the positioning column to limit the light guide column circumferentially, and can use the cooperation of the positioning column, the circuit board and the support of the light guide column to limit the light guide column axially, thereby achieving effective positioning of the light guide column, avoiding the use of glue bonding or snap-on positioning, and also making the shell structure simpler to design and improving the assembly efficiency of the light guide column. In addition, the present invention uses a positioning column that wraps the catheter column, which can protect the catheter column and avoid the risk of the column breaking in a vibration scenario.

[0016] 2. The outer surface of the shell is provided with a recessed groove corresponding to the through hole at its through hole, and the end of the column away from the support enters the recessed groove, so that the present invention can increase the light transmission area of ​​the light guide column and enhance the luminous effect of the light guide column.

[0017] 3. The end of the column away from the support does not protrude from the outer surface of the shell where the through hole is located, so that the present invention can play a certain protective role on the light guide column and prevent the end of the column away from the support from being hit when the product falls.

[0018] 4. The accommodation portion of the support is an accommodation groove provided at one end of the support facing the circuit board, and the side of the support is provided with at least one concession notch leading to the accommodation groove, so that when the light guide column is installed, the installation direction of the light guide column can be determined by confirming the direction of the concession notch, thereby preventing the support from squeezing the light source; the cross-section of the column is flat, which can prevent the light guide column from rotating and changing the installation direction.

[0019] 5. The cross-sectional dimensions of the column gradually decrease from the end where the column is connected to the support to the end of the column away from the support, so that the outer periphery of the column is wedge-shaped, thereby facilitating demoulding during production of the light guide column and also facilitating the light guide column to pass through the positioning column.

[0020] 6. The provision of the reinforcement structure can improve the strength of the positioning column.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the vehicle body controller of the present invention is not limited to the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] For examples, see Figures 1-9 As shown, a vehicle body controller of the present invention includes a housing, a circuit board 3, and a light guide 2. The circuit board 3 is located within the housing, and a light source is disposed on the circuit board 3. The housing is provided with a through hole 11 corresponding to the light guide 2. The light guide 2 includes a support 22 and a column 21 disposed on the support 22. The housing is provided with a hollow positioning column 12 corresponding to the through hole 11. The column 21 of the light guide 2 is sequentially inserted through the positioning column 12 and the through hole 11, and the end of the positioning column 12 facing away from the through hole 11 abuts the support 22. The support 22 abuts the circuit board 3. The light source corresponds to the support 22. Specifically, the support 22 is provided with a recess, and the light source enters the recess of the support 22. The housing specifically includes an upper shell 1 and a lower shell 4, which are connected vertically and form a housing cavity. The circuit board 3 is located within the housing cavity. The through hole 11 and the positioning column 12 are disposed on the top wall of the upper shell 1. The positioning post 12 is specifically formed by extending downward from the location of the through hole 11 on the inner wall surface of the housing (i.e., the inner wall surface of the top wall of the upper shell 1), and the bottom end of the positioning post 12 (i.e., the end of the positioning post 12 facing away from the through hole 11) is suspended in the air before the light guide column 2 is installed. The support 22 and column body 21 of the light guide column 1 are integrally formed, but the present invention is not limited to this.

[0033] In this embodiment, the outer surface of the housing (i.e., the outer surface of the top wall of the upper housing 1) is provided with a recess 13 corresponding to and connected to the through hole 11, and the end of the column 21 facing away from the support 22 enters the recess 13. The end of the column 21 facing away from the support 22 does not protrude beyond the outer surface of the housing where the through hole 11 is located, that is, the top of the column 21 is higher than the bottom of the recess 13, but lower than the upper surface of the upper housing 1. Therefore, if the device falls, the upper surface of the upper housing 1 will first contact the impact surface, preventing the top of the light guide column 2 from being hit, thereby providing a certain degree of protection for the light guide column 2.

[0034] In this embodiment, the accommodation portion of the support 22 is an accommodation groove 221 provided at one end of the support 22 facing the circuit board 3. The side of the support 22 is provided with at least one clearance notch 222 leading to the accommodation groove 221. The clearance notch 222 is used to appropriately avoid the light source to prevent it from being stuck. At the same time, the installation direction of the light guide column can be determined by confirming the direction of the clearance notch 222. The cross-sectional shape of the column 21 is flat, which can prevent the light guide column from rotating and changing the installation direction. The cross-sectional shape of the positioning column 12 and the shape of the through hole 11 are adapted to the cross-sectional shape of the column 21. Specifically, the cross-sectional shape of the column 21 is elliptical, but not limited to this. In other embodiments, the cross-sectional shape of the column is square. The cross-sectional shape of the positioning column 12 and the shape of the through hole 11 are also elliptical. The support 22 has two clearance notches 222, which are distributed along the length of the cross-section of the column 21. However, this is not limiting. In other embodiments, the two clearance notches are distributed along the width of the cross-section of the column. This allows the light guide 2 to be installed in the correct direction by identifying the orientation of the clearance notches 222, preventing the support 22 from squeezing the light source.

[0035] In this embodiment, the dimension of the column 21 in a direction perpendicular to its axial direction gradually decreases from the end of the column 21 connected to the support 22 to the end of the column 21 away from the support 22. Since the cross-section of the column 21 is elliptical, the dimension of the cross-section of the column 21 includes the length and width of the cross-section of the column 21, that is, the length and width of the cross-section of the column 21 gradually decrease from the end of the column 21 connected to the support 22 to the end of the column 21 away from the support 22. If the cross-section of the column 21 is circular, the dimension of the cross-section of the column 21 refers to the radial dimension of the column 21 (that is, the diameter of the column 21). In this way, the outer periphery of the column 21 is wedge-shaped, which facilitates the demolding of the light guide column 2 during production, and also facilitates the light guide column 2 to pass through the positioning column 12.

[0036] In this embodiment, the outer circumference of the positioning column 12 is provided with a reinforcement structure connected to the inner wall of the shell. The reinforcement structure includes a plurality of reinforcement members distributed along the circumference of the positioning column 12 at intervals on the outer circumference of the positioning column 12. Each reinforcement member is a reinforcement rib or a reinforcement plate and is respectively located in the longitudinal direction of the positioning column 12. Figure 4 、 Figure 5As shown, the reinforcement member is specifically a reinforcement plate 14, and there are two of them. These reinforcement plates 14 are located on opposite sides of the positioning column 12, and the opposing outer sides of the two reinforcement plates 14 are respectively fixedly connected to two fixing plates 15 provided along the longitudinal direction of the upper shell 1. This reinforcement structure can enhance the strength of the positioning column 12, preventing the positioning column 12 from breaking or deforming when the product is hit or dropped, thereby better positioning the light guide column 2.

[0037] In this embodiment, the light source is an LED light source 31 , which is a multi-color LED capable of displaying red, green, and blue colors, representing the three communication states of CAN communication: fault, upgrade, and normal, respectively.

[0038] A vehicle body controller of the present invention has a light guide column 2 that is installed vertically from top to bottom and fixed to the upper shell 1 through the circuit board 3. Specifically, the light guide column 2 is inserted into the positioning column 12 from the bottom of the upper shell 1, and the circuit board 3 is installed on the lower shell 4. After the upper shell 1 and the lower shell 4 are engaged, the lower end of the positioning column 12 abuts against the top surface of the support 22 of the light guide column 2, and the bottom surface of the support 22 abuts against the upper surface of the circuit board 3, thereby reliably and effectively fixing the light guide column 2 between the upper shell 1 and the circuit board 3. In addition, the positioning column 12 covers the column 21 of the conduit column, which can also protect the light guide column 2 and reduce the risk of the column 21 of the light guide column 2 with a certain length being broken under vibration. It also makes the positioning column 12 partially completely prevent foreign objects from intruding, and has an IP50 protection effect. At this time, the top of the column 21 of the light guide column 2 is higher than the bottom surface of the sink 13, and the LED light source 31 just enters the accommodation groove 221.

[0039] To ensure that the lower end of positioning post 12 effectively mates with the top surface of support 22 of light guide 2 and maintains the protective performance of light guide 2, the tolerance of positioning post 12 is reduced by controlling the mold precision during the production of upper shell 1. Compared to existing technologies, this invention simplifies the assembly process of light guide 2 and reduces the complexity of the molds for light guide 2 and upper shell 1, thereby reducing costs.

[0040] During normal operation, the LED light source 31 emits light, which in turn transmits light through the support 22 and body 21 of the light guide column 2 and propagates upward to the outside of the upper shell 1. Because the upper shell 1 has a recessed groove 13 on its outer surface at the through hole 11, the end of the body 21 facing away from the support 22 enters the recessed groove 13. Therefore, the present invention can increase the light transmission area of ​​the body 21 of the light guide column 2 while ensuring that the body 21 of the light guide column 2 is not impacted when the product is dropped, thereby enhancing the luminous effect of the light guide column 2.

[0041] The vehicle body controller of the present invention, the parts not involved are the same as those in the prior art or can be implemented by using the prior art.

[0042] The above embodiments are only used to further illustrate a vehicle body controller of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the technical solution of the present invention.
