[0004] Therefore, this utility model embodiment proposes a side tube locking component, which can reduce the space occupied in the width direction of the vehicle, improve the overall space utilization, and facilitate the installation and arrangement of other components.

[0005] Secondly, since the locking component is a single structural part, only the assembly accuracy of the locking component and the side tube needs to be ensured during assembly, which avoids the assembly tolerance of sheet metal and nuts in the existing technology, thereby improving the overall assembly accuracy and consistency.

The first hole, the second hole, and the third hole all extend along the height direction of the locking member, and in the height direction, the height dimension of the middle section is smaller than either the height dimension of the first end or the second end.

[0012] In some embodiments, the locking member has a first side and a second side arranged opposite to each other in the height direction, the first end and the second end both protruding from the middle section on the first side to form a groove on the first side for embedding a battery compartment support strip, and the second side for fitting and fixing to the side tube of the vehicle frame.

[0013] In some embodiments, the first end, the second end, and the middle section are flush with the second side.

[0014] In some embodiments, the groove width gradually decreases along the direction from the groove opening to the groove bottom.

[0015] In some embodiments, the middle section is provided with a protrusion that protrudes to one side of the width direction of the locking member, and the third hole is arranged opposite to the protrusion in the width direction.

[0036] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0038] In the prior art, the locking structure is in the form of sheet metal and nuts. Since nuts are usually standard parts, the nuts are large in size along the width direction of the vehicle, which occupies a lot of space in the width direction, thus making it difficult to install and arrange other parts.

[0039] Secondly, since the sheet metal needs to be fitted with nuts, it will also occupy some space in the width direction of the vehicle, thus further increasing the space occupied.

[0040] In addition, sheet metal and nuts need to be installed and fixed by welding and other methods. During the installation process, there are assembly tolerances for sheet metal and nuts, which results in low overall assembly accuracy and reduces overall assembly consistency.

[0041] Based on the above problems and facts, this utility model proposes a side tube locking component (hereinafter referred to as the locking component).

[0042] like Figure 1 As shown, the locking component 100 of this utility model embodiment includes a first end 1, a second end 2, and a middle section 3.

[0043] The first end 1, the second end 2, and the middle section 3 can be integrally formed. For example, the locking part 100 can be a casting, and the material can be a hard material such as steel. The first end 1, the second end 2, and the middle section 3 can be integrally formed by casting.

[0044] like Figure 1 As shown, the locking member 100 can be elongated and extend along the front-to-back direction, meaning the length of the locking member 100 can be in the front-to-back direction. The first end 1 can be the front end portion of the locking member 100, the second end 2 can be the rear end portion of the locking member 100, and the middle section 3 can generally extend along the front-to-back direction. The middle section 3 connects the first end 1 and the second end 2, meaning the front end of the middle section 3 can be connected to the first end 1, and the rear end of the middle section 3 can be connected to the second end 2.

[0045] The first end 1 is provided with a first hole 11, the second end 2 is provided with a second hole 21, and the middle section 3 is provided with a third hole 31. The first hole 11, the second hole 21, and the third hole 31 all extend along the height direction of the locking member 100.

[0046] For example, such as Figure 1 As shown, the height direction of the locking component 100 can be vertical. The first end 1 has a first hole 11, which can be a round hole and can penetrate the first end 1 vertically. The second end 2 has a second hole 21, which can also be a round hole and can penetrate the second end 2 vertically. The third hole 31 can be located in the middle of the middle section 3, and can also be a round hole and can penetrate the middle section 3 vertically. In use, the first hole 11, the second hole 21, and the third hole 31 can all allow fasteners such as bolts to pass through, thus facilitating the installation and fixing of items such as foot pedals and support strips.

[0047] In the height direction, the height dimension of the middle section 3 is smaller than the height dimension of either the first end 1 or the second end 2. For example, as Figure 1 As shown, the height dimension of the first end 1 can be dimension H1, the height dimension of the second end 2 can be dimension H2, and the height dimension of the middle section 3 can be dimension H3, wherein dimension H1 is greater than dimension H3, and dimension H2 is also greater than dimension H3.

[0048] This allows the upper surface of the locking component 100 to exhibit undulations, which on the one hand facilitates the differentiation of the first end 1, the second end 2, and the middle section 3, and on the other hand allows the upper surfaces of the first end 1, the second end 2, and the middle section 3 to be spatially misaligned, thereby avoiding assembly interference of components installed on the first end 1, the second end 2, and the middle section 3 respectively.

[0049] In addition, the undulations of the upper surface of the locking member 100 can also make different parts of the locking member 100 adapt to the installation needs of parts of different thicknesses, which is also conducive to enhancing the limiting effect.

[0050] Compared to structures such as nuts, the locking component 100 of this utility model has a smaller size in the left-right direction, which reduces the space occupied in the width direction of the vehicle, improves the overall space utilization, and facilitates the installation and arrangement of other components.

[0051] Secondly, since the locking component 100 is a single structural component, only the assembly accuracy of the locking component 100 and the side tube 200 needs to be ensured during assembly, which avoids the assembly tolerance of sheet metal and nuts in the prior art, and also improves the overall assembly accuracy and consistency.

[0052] In some embodiments, the locking member 100 has a first side 5 and a second side 6 arranged opposite to each other in the height direction. The first end 1 and the second end 2 both protrude from the middle section 3 on the first side 5 to form a groove 4 on the first side 5. The groove 4 is used for the battery compartment support strip 400 to be inserted. The second side 6 is used to fit and fix with the side tube 200 of the frame.

[0053] For example, such as Figure 1As shown, the first side 5 can be the top side of the locking component 100, and the second side 6 can be the bottom side of the locking component 100. Since the height dimensions of the first end 1, the second end 2, and the middle section 3 are different, the first end 1, the second end 2, and the middle section 3 will form a groove 4 on the top side of the locking component 100. Since the battery compartment support strip 400 of the vehicle has a certain thickness, the battery compartment support strip 400 can be embedded in the groove 4 during assembly, thereby enhancing the limiting constraint effect on the battery compartment support strip 400 and avoiding the situation where the battery compartment support strip 400 protrudes too much due to its thickness. In this way, the protruding battery compartment support strip 400 can be avoided from interfering with the assembly of other components.

[0054] In some embodiments, the first end 1, the second end 2, and the middle section 3 are flush with the second side 6. For example, as... Figure 1 As shown, the lower surfaces of the first end 1, the second end 2, and the middle section 3 can be arranged in a coplanar manner. Therefore, during assembly, the first end 1, the second end 2, and the middle section 3 can simultaneously come into contact with the side tube 200, thereby ensuring the structural stability of the assembly.

[0055] In some embodiments, the width of the groove 4 gradually decreases along the direction from the opening of the groove 4 to the bottom of the groove 4. For example, as Figure 1 As shown, the first end 1 includes a first inclined wall 12 facing the rear side, and the second end 2 includes a second inclined wall 22 facing the front side. The first inclined wall 12 and the second inclined wall 22 are arranged opposite to each other in the front-rear direction, wherein the first inclined wall 12 can be arranged inclined downward in a direction from front-up to rear-down, and the second inclined wall 22 can be arranged inclined downward in a direction from rear-up to front-down.

[0056] The groove width of the groove 4 can be the distance between the first inclined wall 12 and the second inclined wall 22 in the front-to-back direction. This distance can gradually decrease from top to bottom. This gradual change facilitates the assembly and embedding of the battery compartment support strip 400.

[0057] In some embodiments, the middle section 3 is provided with a protrusion 32, which protrudes to one side of the locking member 100 in the width direction, and in the width direction, the third hole 31 is arranged opposite to the protrusion 32.

[0058] For example, such as Figure 1 As shown, the protrusion 32 can be integrally formed on the left side of the middle section 3. The protrusion 32 can extend along the vertical direction, and the cross-section of the protrusion 32 in the horizontal direction can be arched, semi-circular, etc.

[0059] When the width of the locking component 100 in the left-right direction is narrow, the third hole 31 is difficult to machine. The protrusion 32 can increase the local width of the middle section 3, thus facilitating casting. Secondly, the protrusion 32 can also enhance the local structural strength and rigidity, thereby reducing the impact of the reduced structural strength caused by the third hole 31.

[0060] In some embodiments, the first hole 11, the second hole 21, and the third hole 31 are not collinearly arranged along the length of the lock accessory. For example, as... Figure 1 As shown, the length direction of the locking component 100 can be the front-to-back direction. In the front-to-back direction, the first hole 11 and the second hole 21 can be arranged facing each other, while the third hole 31 can be arranged obliquely opposite to the first hole 11 and the second hole 21. That is, the center of the third hole 31 can be located beside the line connecting the center of the first hole 11 and the center of the second hole 21.

[0061] This allows the first hole 11, the second hole 21, and the third hole 31 to be arranged in a triangular pattern, thereby improving the overall structural stability after fasteners are assembled.

[0062] In some embodiments, the first hole 11, the second hole 21, and the third hole 31 all penetrate the locking member 100 along the height direction. That is, the first hole 11, the second hole 21, and the third hole 31 can all be through holes. In other embodiments, the first hole 11, the second hole 21, and the third hole 31 can also be blind holes, etc.

[0063] In some embodiments, the first hole 11, the second hole 21, and the third hole 31 are all threaded holes. That is, the inner peripheral walls of the first hole 11, the second hole 21, and the third hole 31 are all provided with internal threads, thereby facilitating connection and fixation with bolts.

[0064] The vehicle frame of an embodiment of this utility model is described below.

[0065] The frame of this utility model embodiment includes two side tubes 200 and a locking member 100. The locking member 100 can be the locking member 100 described in any of the above embodiments. The two side tubes 200 are arranged opposite to each other, and each side tube 200 is provided with at least one locking member 100.

[0066] For example, such as Figure 2 As shown, the two side tubes 200 of the frame can be arranged opposite each other in the left and right direction. Each side tube 200 can be fixed with two locking parts 100 by welding. In some other embodiments, each side tube 200 can also be arranged with only one locking part 100.

[0067] In some embodiments, the locking member 100 is disposed on the top side of the side tube 200, and the length direction of the locking member 100 is consistent with the extension direction of the side tube 200. For example, as Figure 2 As shown, the locking component 100 can be fixed to the top side of the side tube 200 by welding. The length direction of the locking component 100 and the extension direction of the side tube 200 can both be in the front-back direction. Therefore, the projection of the locking component 100 in the vertical direction can be completely within the projection range of the side tube 200, which is beneficial to improving the compactness of the assembly.

[0068] In some embodiments, each side tube 200 is provided with a plurality of locking members 100, the plurality of locking members 100 on each side tube 200 are arranged at intervals along the extension direction of the side tube 200, and the plurality of locking members 100 on two side tubes 200 are respectively arranged opposite to each other in the opposite direction of the two side tubes 200.

[0069] For example, such as Figure 2 As shown, each side tube 200 may be provided with two locking members 100, and the two locking members 100 of each side tube 200 may be arranged at intervals in the front-rear direction. The locking members 100 on the front side of the two side tubes 200 may form one pair, and the locking members 100 on the rear side of the two side tubes 200 may form another pair. Each pair of locking members 100 may be arranged facing each other in the left-right direction. This ensures the symmetry and consistency of the left and right sides of the frame structure.

[0070] In some other embodiments, each side tube 200 may also be provided with three, four or more locking elements 100.

[0071] The vehicle according to an embodiment of the present invention is described below.

The battery compartment support strip 400 corresponds to the middle section 3 and is connected to the middle section 3 through the third hole 31.

[0073] For example, the top of the battery compartment support strip 400 may be provided with a hanging ear, which can overlap the top side of the middle section 3, and the hanging ear can be connected and fixed to the middle section 3 by fasteners. It should be noted that there may be multiple battery compartment support strips 400, and the middle section 3 of the locking member 100 on each side tube 200 can be connected and fixed to the hanging ear of the corresponding battery compartment support strip 400.

[0074] The battery retaining strip 300 can be long and can extend in the left and right direction. The left end of the battery retaining strip 300 can be connected and fixed to the first end 1 of the locking member 100 on the left side tube 200, and the right end of the battery retaining strip 300 can be connected and fixed to the first end 1 of the locking member 100 on the right side tube 200. The connection and fixing method can be fastener fixing.

[0075] The foot pedal can be fastened to multiple locking parts 100, and the foot pedal can be connected and fixed to the second end 2 on each locking part 100. The connection and fixing method can also be fastening with fasteners.
