The following describes the implementation of the present invention based on its overall structure.

[0044] Reference Figure 1 As shown, an embodiment of the present application provides a bolt connection structure, comprising:

[0045] The bolt member 1 has a head portion 11 and a body portion 12;

[0046] The mounting plate 2 is sleeved on the main body 12, and the mounting plate 2 is in contact with the head 11;

[0047] The connecting plate 3 is sleeved on the main body 12, and the connecting plate 3 is in conflict with the mounting plate 2;

[0048] A nut member 4 is sleeved on the main body 12, and the nut member 4 contacts the mounting plate 2 to tighten the mounting plate 2 and the connecting plate 3;

[0049] The head portion 11 has a protrusion 13 on the end side facing the main body portion 12 , and the protrusion 13 is riveted to the mounting plate 2 ; the head portion 11 is inserted into the injection-molded housing 5 .

[0050] according to Figure 1 Those skilled in the art can set the bolt member 1 to connect with the mounting plate 2, the connecting plate 3, the nut member 4 and the injection molded housing 5.

[0051] Specifically, those skilled in the art can configure the bolt member 1 to have a head 11 and a body 12. The mounting plate 2 and the connecting plate 3 are both sleeved onto the body 12, with the mounting plate 2 abutting against the head 11 and the connecting plate 3 abutting against the mounting plate 2. The nut member 4 is then installed on the body 12, with the nut member 4 mounted on the side of the connecting plate 3 away from the mounting plate 2, with the nut member 4 abutting against the connecting plate 3.

[0052] It is understood that the main body 12 of the bolt member 1 is provided with a connecting thread, which can be used to connect with the nut member 4. After the nut member 4 is connected to the main body 12, it can be tightened toward the position where the mounting plate 2 and the connecting plate 3 are located, thereby pressing the mounting plate 2 and the connecting plate 3 together.

[0053] With the above structure, those skilled in the art can provide a protrusion 13 on the end side of the head portion 11 facing the main body portion 12 , and the protrusion 13 is riveted to the mounting plate 2 .

[0054] In the above arrangement, the protrusion 13 can be embedded into the mounting plate 2 by riveting. Furthermore, those skilled in the art can arrange for the head 11 of the bolt member 1 to penetrate into the injection-molded housing 5 .

[0055] In this embodiment, the head 11 of the bolt 1 is inserted into the injection-molded housing 5 , and the injection-molded housing 5 can be injection-molded to complete the overall structural connection.

[0056] It is understood that in the above arrangement, before the injection molding process is performed on the injection-molded housing 5, the protrusion 13 is embedded in the mounting plate 2 by riveting, thereby positioning the bolt member 1. The above arrangement eliminates the need to position the bolt member 1 during the injection molding process, simplifies the injection molding process while maintaining the connection strength of the bolt member 1, and thus reduces production costs.

[0057] In an optional embodiment, the connection plate 3 and the mounting plate 2 are preferably made of conductive materials. In other words, those skilled in the art can use the above-described embodiment to connect the conductive connection plate 3 and the mounting plate 2. The connection plate 3 can be configured as a conductive product such as a terminal, while the mounting plate 2 is made of a material such as copper.

[0058] In the above structure, positioning of the bolt member 1 is avoided during the injection molding process, thereby reducing the opening size of the mounting plate 2 and further increasing the current-carrying area.

[0059] In the above structure, the protrusion 111 is embedded in the mounting plate 2 by riveting, thereby preventing the mounting plate 2 and the connecting plate 3 from being separated from the injection molded structure due to vibration during use of the structure connected by the bolt member 1 .

[0060] according to Figure 1 The bolt member 1 may be further configured in this field. Preferably, the head 11 has a groove 112 for accommodating the injection molding material in the injection molding housing 5. That is, after the injection molding process is completed, the injection molding material can be filled into the groove 112, thereby forming a structure in which the groove 112 and the injection molding material interfere with each other.

[0061] With the above structure, the interference between the receiving groove 112 and the injection molding material can improve the connection strength between the head 11 of the bolt member 1 and the injection molding material, thereby avoiding the connection failure of the connection structure of the head 11.

[0062] In the above structure, the mounting plate 2 and the connecting plate 3 are connected in abutting manner. Preferably, the outer diameter of the mounting plate 2 is larger than the outer diameter of the connecting plate 3, so that the connection between the mounting plate 2 and the connecting plate 3 can be more stable.

[0063] In one embodiment, preferably, the plane where the connecting plate 3 is located is parallel to the plane where the mounting plate 2 is located. The connecting plate 3 and the mounting plate 2 being parallel to each other can make the installation structure of the bolt member 1 more stable.

[0064] according to Figure 2 In an optional embodiment, preferably, the inner wall of the connecting plate 3 is kept separate from the outer wall of the main body 12, so that the connecting plate 3 can be stably positioned and mounted during installation.

[0065] To sum up, those skilled in the art have provided a groove 112 on the head 11, the outer diameter of the mounting plate 2 is larger than the outer diameter of the connecting plate 3, the plane where the connecting plate 3 is located is parallel to the plane where the mounting plate 2 is located, and the inner wall of the connecting plate 3 is kept separate from the outer wall of the main body 12, thereby making the structure of the connection of the bolt member 1 more stable and significantly improving the reliability of the connection structure of the bolt member 1.

[0066] The embodiment of the present application further provides a bolt structure, comprising:

[0067] The bolt member 1 has a main body 12;

[0068] The head portion 11 and the guide portion 13 are respectively provided at both ends of the main body portion 12 . A protrusion 111 is installed on the side wall of the head portion 11 facing the guide portion 13 . The protrusion 111 is used for riveting to the plate.

[0069] In the above structure, the main body of the bolt member 1 has opposite ends for providing the head 11 and the guide portion 13. It is understood that the provision of the guide portion 13 can facilitate positioning of the bolt member 1, and the provision of the head 11 can facilitate installation of the bolt member 1.

[0070] Furthermore, those skilled in the art have provided a protrusion 111 on the side wall of the head 11 facing the guide portion 13, and the protrusion 111 is used to rivet with the plate. The provision of the guide portion 13 can prevent the bolt 1 from falling out and rotating when connecting the plate to the bolt 1.

[0071] In the above structure, the protrusion 111 is embedded in the plate after being riveted to the plate, so that the bolt member 1 can be positioned by the embedded structure during the installation process.

[0072] In an optional embodiment, preferably, the raised portion 111 is composed of a plurality of spaced tooth-shaped blocks. It is understandable that the raised portion 111 of the tooth-shaped block can be more easily embedded into the plate during the riveting process, thereby improving the efficiency of the riveting.

[0073] More preferably, multiple tooth-like blocks are distributed circumferentially along the sidewall of the head portion 11, and each of the tooth-like blocks is connected to the main body portion 12. The circumferential distribution of multiple tooth-like blocks along the sidewall of the head portion 11 can ensure more uniform force distribution within the raised portion 111. Furthermore, the connection of multiple tooth-like blocks to the main body portion 12 can provide a more stable structure for the raised portion 111, allowing it to withstand greater torque.

[0074] In an optional embodiment, the head 11 preferably has a groove 112 for accommodating the injection molding material in the injection molding housing 5. During the injection molding process, the interference between the groove 112 and the injection molding material can improve the connection strength between the head 11 of the bolt member 1 and the injection molding material, thereby avoiding the connection failure of the connection structure of the head 11.

[0075] In the arrangement of the head 11, preferably, a plurality of protrusions 14 are provided on the side wall of the head 11 facing the direction of the groove 112, and the protrusions 14 are used to connect with the plate. In this embodiment, those skilled in the art can arrange that a plurality of protrusions 14 are further provided on the head 11, according to Figure 8 , a plurality of protrusions 14 are arranged on the side wall opposite to the raised portion 111 .

[0076] With the above structure, the head 11 and the plate or the injection molded material in the injection molded housing 5 are engaged with each other to form a mutually interfering structure. It is understood that the mutually interfering structure can provide a force to prevent rotation during the engagement of the head 11, thereby improving the reliability of the connection portion of the head 11.

[0077] More preferably, the plurality of protrusions 14 may be arranged at even intervals, thereby providing a uniform anti-rotation force in the structure connected to the head 11 , thereby further improving the reliability of the connection portion of the head 11 .

[0078] In an alternative embodiment, a plurality of grooves 15 are formed on the side of the head 11 away from the guide portion 13 for connection with the plate. In this embodiment, the plurality of grooves 15 are provided on the side wall opposite the protrusion 111, so that the injection material of the plate or the injection-molded housing 5 can be squeezed into the grooves 15 to form a mutually blocking structure.

[0079] The aforementioned blocking structure can generate a force to prevent rotation when the head 11 has a tendency to rotate or is rotating, thereby further stabilizing the structure of the head 11 connection. More preferably, the multiple grooves 15 are evenly spaced. Evenly spaced grooves 15 can generate a uniform force to prevent rotation when the head 11 has a tendency to rotate or is rotating, thereby significantly improving the stability of the head 11 connection structure.

[0080] Those skilled in the art will further configure the head 11. Preferably, the head 11 includes a boss 16, the outer edge of which is configured as a closed arc, polygon, or multi-segment closed connection. In other words, the boss 16 on the head 11 can be embedded in the sheet material or the injection molded material of the injection molded housing 5 when the head 11 is connected. The closed arc, polygon, or multi-segment closed connection of the boss 16 allows the boss 16 to form a structure that interferes with the sheet material or the injection molded material of the injection molded housing 5, thereby preventing the head 11 of the bolt 1 from rotating and failing.
