[0002] In the field of electric golf carts, some high-end golf carts typically use aluminum profile B-pillars to enhance the overall quality of the vehicle.

[0003] In traditional B-pillar installation structures, the B-pillar is directly connected to the roof frame using bolts.

[0004] However, the aluminum profile B-pillars and roof frame use a traditional installation structure, which has problems such as exposed bolts, unsightly appearance, and potential for scratching passengers. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a B-pillar mounting structure for a golf cart, in which a connector is provided between the B-pillar and the roof frame. This connector can shield the bolts from the side, preventing the bolts from scratching passengers.

[0006] A B-pillar mounting structure for a golf cart according to an embodiment of the present invention includes: The roof frame is provided with crossbeams, and the crossbeams are provided with first bolts; The B-pillar has a second bolt at its top. A connector is disposed between the top of the ceiling frame and the top of the B-pillar. The top of the connector has two parallel connecting plates, forming a first mounting groove between the two connecting plates to accommodate the crossbeam. Each connecting plate has a first through hole for installing the first bolt. Two first baffles are disposed on the side of the connecting plate facing away from the first mounting groove, with the first bolt located between the two first baffles. The two first baffles respectively cover both sides of the first bolt. The bottom of the connector has a second mounting groove for accommodating the top of the B-pillar. The connector has a second through hole penetrating the second mounting groove for installing the second bolt. The outer wall of the connector also has a first protruding ring, with the second bolt located inside the first protruding ring, which covers the radially outer side of the second bolt.

[0007] The B-pillar mounting structure of a golf cart according to an embodiment of the present invention has at least the following beneficial effects: 1. This utility model provides a stable and reliable connection structure between the roof frame beam and the B-column by setting up a connector, through which the first mounting groove and the second mounting groove of the connector respectively cooperate with the top of the roof frame beam and the B-column, thereby simplifying the installation process.

[0008] 2. This utility model effectively avoids bolt exposure by using the first baffle of the connector to cover both sides of the first bolt and the first convex ring to cover the radial outer side of the second bolt, thereby improving the overall appearance and eliminating the risk of bolts scratching passengers.

[0009] According to some embodiments of the present invention, the top wall of the connector is located below the first bolt, and the top wall of the connector can cover the bottom of the first bolt.

[0010] The advantages are: by having the top wall of the connector cover the first bolt from the bottom, the first bolt is further prevented from being exposed, which enhances the comprehensiveness of the covering effect and improves safety and aesthetics.

[0011] According to some embodiments of the present invention, the bottom of the top wall of the connector is provided with reinforcing ribs.

[0012] The advantages of this invention are: by setting reinforcing ribs at the bottom of the top wall of the connector, the reinforcing ribs significantly enhance the structural rigidity and strength of the connector, prevent the top wall of the connector from deforming under stress, and improve the stability and lifespan of the installation structure.

[0013] According to some embodiments of the present invention, the outer peripheral wall of the first convex ring is inclined.

[0014] The advantage of this invention is that by tilting the outer peripheral wall of the first convex ring, the appearance of the first convex ring becomes more streamlined, sharp edges are reduced, and aesthetics are improved.

[0015] According to some embodiments of the present invention, there is a first clearance gap between the inner wall of the first convex ring and the second bolt. The first clearance gap is used to allow a wrench tool to pass through, and the wrench tool is used to tighten the second bolt.

[0016] The advantages of this invention are: by creating a first clearance gap between the inner wall of the first convex ring and the second bolt, the first clearance gap provides operating space for the wrench tool, making it easier to tighten and loosen the second bolt, improving the efficiency of installation and maintenance, and ensuring that the second bolt is covered while taking into account practicality and maintainability.

[0017] According to some embodiments of the present invention, the connector includes two long sidewalls and two short sidewalls. One sidewall is connected to one side of the two long sidewalls, and the other sidewall is connected to the other side of the two long sidewalls. A second mounting groove is formed between the two long sidewalls and the two short sidewalls. A second through hole penetrates the two long sidewalls. The first protruding ring is disposed on the outside of the long sidewalls.

[0018] The advantages of this invention are as follows: By including two long sidewalls and two short sidewalls in the connector, with one side of each of the two short sidewalls connecting to one side of the two long sidewalls respectively, and the other side of each of the two short sidewalls connecting to the other side of the two long sidewalls respectively, a second mounting groove is formed between the two long sidewalls and the two short sidewalls, and a second through hole penetrates through the two long sidewalls. A first protruding ring is disposed on the outer side of the long sidewall. Thus, on the one hand, the structural design of the connector is reasonable, making the second mounting groove more accurately match the top of the B-pillar and improving the connection stability. On the other hand, the layout of the long and short sidewalls is easy to manufacture and assemble, reducing production costs. Moreover, the dimensional difference between the long and short sidewalls facilitates the accurate positioning of the second mounting groove with the B-pillar.

[0019] According to some embodiments of the present invention, the connection between the long sidewall and the short sidewall is a circular arc transition.

[0020] The advantages are: by making the connection between the long sidewall and the short sidewall rounded, the connection reduces stress concentration, improves the fatigue resistance of the connector, and extends its service life. At the same time, it avoids sharp corners, improves safety, and prevents people from being scratched during installation or use.

[0021] According to some embodiments of the present invention, the short sidewall is provided with an inwardly protruding first protrusion, and the sidewall of the B-pillar is provided with a vertically extending first groove, wherein the first protrusion and the first groove cooperate to limit the movement.

[0022] The advantages of this invention are: by providing an inwardly protruding first protrusion on the short sidewall and a vertically extending first groove on the sidewall of the B-pillar, the first protrusion and the first groove cooperate to limit the positioning. Thus, the cooperation between the first protrusion and the first groove provides additional positioning and anti-rotation functions, ensuring that the B-pillar will not be misaligned or rotated during installation, enhancing connection accuracy and reliability, simplifying the installation process, and reducing adjustment time.

[0023] According to some embodiments of the present invention, the cross-section of the B-pillar is frame-shaped, the outer contour of the cross-section of the B-pillar matches the shape of the cross-section of the second mounting groove, the inner wall of the B-pillar is provided with a second protrusion, and the second bolt passes through the second protrusion.

[0024] The advantages are: by making the cross-section of the B-pillar frame-shaped, the outer contour of the B-pillar cross-section matches the shape of the cross-section of the second mounting groove. Thus, the matching design between the B-pillar and the connector improves the fit, enhances the connection strength, and distributes the load. In addition, the second protrusion provides a more secure second bolt support fixing point, reduces the stress on the side wall of the B-pillar, and prevents the side wall of the B-pillar from deforming.

[0025] According to some embodiments of this utility model, the connector is made of plastic.

[0026] The advantages of this invention are: by setting the connecting parts as plastic parts, on the one hand, the plastic parts are lightweight, which helps to reduce the overall vehicle weight and improve energy efficiency; on the other hand, plastic is low in cost and easy to injection mold, which can mass-produce complex shapes and reduce manufacturing costs; furthermore, the indirect connection between the crossbeams of the roof frame and the B-pillars through the plastic parts can eliminate abnormal noises between the crossbeams and B-pillars and the connecting parts, and avoid the abnormal noises caused by the swaying of the roof frame and the metal collision and friction between the B-pillars during driving caused by the direct connection between the crossbeams and B-pillars, thus improving the passenger driving experience.

The connector 150 is provided with a second through hole 210 that penetrates the second mounting groove 200. The second through hole 210 is used to install the second bolt 140. The outer side wall of the connector 150 is also provided with a first protruding ring 220. The second bolt 140 is located inside the first protruding ring 220. The first protruding ring 220 is used to cover the radial outer side of the second bolt 140.

[0043] It is understood that, in this embodiment, by setting up a connector 150, the first mounting groove 170 and the second mounting groove 200 of the connector 150 respectively cooperate with the top of the crossbeam 110 and the B-column 130 of the ceiling frame 100, thereby providing a stable and reliable connection structure between the crossbeam 110 and the B-column 130 of the ceiling frame 100 and simplifying the installation process.

[0044] In this embodiment, the first baffle 190 of the connector 150 covers both sides of the first bolt 120, and the first convex ring 220 covers the radial outer side of the second bolt 140, which effectively avoids the bolt being exposed, improves the overall appearance of the vehicle, and eliminates the risk of the bolt scratching passengers.

[0045] In some specific embodiments, the top wall of the connector 150 is located below the first bolt 120, and the top wall of the connector 150 can cover the bottom of the first bolt 120.

[0046] It is understood that this embodiment further prevents the first bolt 120 from being exposed by having the top wall of the connector 150 cover the first bolt 120 from the bottom, thereby enhancing the comprehensiveness of the covering effect and improving safety and aesthetics.

[0047] In some specific embodiments, the bottom of the top wall of the connector 150 is provided with reinforcing ribs 230.

[0048] It is understood that, in this embodiment, by providing a reinforcing rib 230 at the bottom of the top wall of the connector 150, the reinforcing rib 230 significantly enhances the structural rigidity and strength of the connector 150, prevents the top wall of the connector 150 from deforming under stress, and improves the stability and lifespan of the installation structure.

[0049] In some specific embodiments, the outer peripheral wall of the first protruding ring 220 is inclined, thereby making the first protruding ring 220 more streamlined in appearance, reducing sharp edges and improving aesthetics.

[0050] In some specific embodiments, there is a first clearance gap 240 between the inner wall of the first protruding ring 220 and the second bolt 140. The first clearance gap 240 is used to avoid the wrench tool, which is used to tighten the second bolt 140.

[0051] It is understood that this embodiment provides a first clearance gap 240 between the inner wall of the first convex ring 220 and the second bolt 140, which provides operating space for the wrench tool, making it easier to tighten and loosen the second bolt 140, improving the efficiency of installation and maintenance, and ensuring that the second bolt 140 is covered while taking into account practicality and maintainability.

[0052] In some specific embodiments, the connector 150 includes two long sidewalls 250 and two short sidewalls 260. The two sides of one short sidewall 260 are respectively connected to one side of the two long sidewalls 250, and the two sides of the other short sidewall 260 are respectively connected to the other side of the two long sidewalls 250. A second mounting groove 200 is formed between the two long sidewalls 250 and the two short sidewalls 260. A second through hole 210 penetrates the two long sidewalls 250. A first protruding ring 220 is disposed on the outer side of the long sidewall 250. Thus, on the one hand, the structural design of the connector 150 is reasonable, making the matching of the second mounting groove 200 with the top of the B-pillar 130 more precise and improving the connection stability. On the other hand, the layout of the long sidewalls 250 and the short sidewalls 260 is easy to manufacture and assemble, reducing production costs. Moreover, the size difference between the long sidewalls 250 and the short sidewalls 260 facilitates the accurate positioning of the second mounting groove 200 and the B-pillar 130 during installation.

[0053] Furthermore, the connection between the long sidewall 250 and the short sidewall 260 is rounded, which reduces stress concentration, improves the fatigue resistance of the connector 150, extends its service life, avoids sharp corners, improves safety, and prevents people from being scratched during installation or use.

[0054] Reference Figure 6 In some specific embodiments, the short sidewall 260 is provided with an inwardly protruding first protrusion 270, and the sidewall of the B-pillar 130 is provided with a vertically extending first groove 280. The first protrusion 270 and the first groove 280 cooperate to limit the movement. Thus, the cooperation between the first protrusion 270 and the first groove 280 provides additional positioning and anti-rotation functions, ensuring that the B-pillar 130 will not be misaligned or rotated during installation, thereby enhancing connection accuracy and reliability, simplifying the installation process, and reducing adjustment time.

[0055] In some specific embodiments, the cross-section of the B-pillar 130 is frame-shaped, and the outer contour of the cross-section of the B-pillar 130 matches the shape of the cross-section of the second mounting groove 200. The inner wall of the B-pillar 130 is provided with a second protrusion 290, and the second bolt 140 passes through the second protrusion 290.

[0056] It is understood that in this embodiment, by making the cross-section of the B-pillar 130 frame-shaped, the outer contour of the cross-section of the B-pillar 130 matches the shape of the cross-section of the second mounting groove 200. As a result, the matching design of the B-pillar 130 and the connector 150 improves the fit, enhances the connection strength, and distributes the load. In addition, the second protrusion 290 provides a more secure bolt support fixing point for the second bolt 140, reducing the stress on the side wall of the B-pillar 130 and preventing deformation of the side wall of the B-pillar 130.

[0057] In some specific embodiments, the connector 150 is made of plastic. On the one hand, the plastic component is lightweight, which helps to reduce the overall vehicle weight and improve energy efficiency. On the other hand, plastic is low in cost and easy to injection mold, allowing for the mass production of complex shapes and reducing manufacturing costs. Furthermore, the indirect connection between the crossbeam 110 of the roof frame 100 and the B-pillar 130 via the plastic component can eliminate abnormal noises between the crossbeam 110 and the B-pillar 130 and the connector 150. This avoids the abnormal noises caused by the swaying of the roof frame 100 and the metal collision and friction between the B-pillar 130 during driving due to the direct connection between the crossbeam 110 and the B-pillar 130, thus improving the passenger driving experience.
