Specific embodiments
[0026] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.
[0027] As Figures 1-9 shown, a bumper structure for an electric vehicle according to the present utility model includes a front bumper 1 and a fender 2. An edge pressing strip 101 is fixedly arranged on one side surface of the front bumper 1. A clamping strip 102 is fixedly arranged at the top end of the edge pressing strip 101. A plurality of strip-shaped clamping holes 103 are equidistantly arranged on the surface of the clamping strip 102. An overlapping edge 201 is fixedly arranged on one side of the fender 2. A reinforcing strip 203 is fixedly arranged at the top of the overlapping edge 201. A clamping groove 204 is arranged at the bottom of the reinforcing strip 203. A plurality of strip-shaped clamping blocks 202 are fixedly arranged on the equidistant side edges of the inner wall of the clamping groove 204. The top end of the edge pressing strip 101 is in contact connection with the bottom end of the overlapping edge 201, and the clamping strip 102 is nested inside the clamping groove 204. The strip-shaped clamping blocks 202 are in clamping connection with the strip-shaped clamping holes 103.
[0028] Specifically, between the front bumper 1 and the fender 2, they are cooperated by the clamping strip 102 and the clamping groove 204, and are fixed by the cooperation of the strip-shaped clamping blocks 202 arranged on the side of the clamping groove 204 and the strip-shaped clamping holes 103 arranged on the surface of the clamping strip 102, and are locked by arranging locking components on the side edges of the front bumper 1 and the fender 2, replacing the traditional assembly by a plurality of bolts. This not only improves the tightness of the assembly between the front bumper 1 and the fender 2, but also improves the convenience of the assembly of the front bumper 1 and the fender 2.
[0029] As Figures 1-9 shown, for a bumper structure for an electric vehicle according to the present utility model, a bolt fixing piece 104 which is integrally connected is fixedly arranged on the side of the clamping strip 102. A first locking component 206 and a second locking component 207 are fixedly arranged between the bolt fixing piece 104 and the side surface of the overlapping edge 201.
[0030] Specifically, through the cooperation of the first locking component 206 and the second locking component 207, the firmness of the connection between the front bumper 1 and the fender 2 is improved.
[0031] Both the first locking component 206 and the second locking component 207 are composed of a U-shaped elastic block 2061, a screw 2062, and an annular limiting block 2064. Through holes are provided on both sides of the U-shaped elastic block 2061, and the screw 2062 is inserted through the two through holes. An annular limiting block 2064 integrally fixed is provided at one end of the screw 2062, and the screw 2062 is threadedly connected to the overlap 201 and the bolt fixing piece 104 in sequence.
[0032] A buckle 2063 is fixedly provided at one end of the U-shaped elastic block 2061, and a buckle groove is provided on the side wall of the overlap 201. The buckle 2063 is snap-fitted and fixed with the buckle groove.
[0033] Specifically, through the setting of the U-shaped elastic block 2061, during the tightening process of the screw 2062, the U-shaped elastic block 2061 is deformed under pressure. Through the extrusion force of the U-shaped elastic block 2061, the pressing strip 101 is squeezed to closely fit the side of the overlap 201, improving the tightness of the connection between the front bumper 1 and the fender 2.
[0034] As Figures 1-9 shown, for a bumper structure of an electric vehicle of the present utility model, connection sleeves 205 are fixedly provided on both sides of the top of the overlap 201. The connection sleeves 205 are square. An annular reinforcement block 208 is fixedly provided on the top of the connection sleeve 205, and a threaded hole is provided at the center of the top of the connection sleeve 205.
[0035] Specifically, through the setting of the connection sleeve 205, it can assist in further strengthening the connection part through bolts.
[0036] A rectangular block is fixedly provided at the center of the top of the overlap 201, and a cross-shaped insertion post 209 integrally fixed is provided at the top of the rectangular block.
[0037] Specifically, through the setting of the cross-shaped insertion post 209, when connecting to the electric vehicle frame, it can be assembled by inserting the cross-shaped insertion post 209 into a cross-shaped insertion hole provided on the surface of the frame.
[0038] A plurality of triangular reinforcement pieces 210 are equidistantly and fixedly provided on one side surface of the overlap 201, and the side surfaces of the plurality of triangular reinforcement pieces 210 are fixedly connected to the side surface of the reinforcing strip 203.
[0039] Specifically, through the setting of the triangular reinforcement pieces 210, the structural strength of the connection part of the overlap 201 is improved.
[0040] At equal intervals on the top of the tab 201, a plurality of transverse reinforcement bars 211 and a plurality of longitudinal reinforcement bars 212 are fixedly arranged, and the transverse reinforcement bars 211 and the longitudinal reinforcement bars 212 are arranged in a crosswise manner.
[0041] Specifically, through the arrangement of the transverse reinforcement bars 211 and the longitudinal reinforcement bars 212, the structural strength of the tab 201 is increased.
[0042] The size of the clamping strip 102 is adapted to the inner diameter of the clamping groove 204, and the height of the strip-shaped clamping holes 103 on the surface of the clamping strip 102 is the same as the height of the strip-shaped clamping blocks 202.
[0043] Specifically, the gap between the clamping strip 102 and the clamping groove 204 can be reduced. By making the height of the strip-shaped clamping holes 103 match the height of the strip-shaped clamping blocks 202, the strip-shaped clamping blocks 202 can be accurately engaged with the strip-shaped clamping holes 103.
[0044] L-shaped mating holes are formed on the sides of the plurality of strip-shaped clamping blocks 202.
[0045] Specifically, it is convenient to observe whether the strip-shaped clamping blocks 202 and the strip-shaped clamping holes 103 are fully engaged.
[0046] In specific implementation, when the front bumper 1 needs to be connected to the fender 2, first, the top end of the edge pressing strip 101 is brought into contact with the bottom end of the tab 201. Then, the clamping strip 102 is nested into the interior of the clamping groove 204. Then, the clamping strip 102 is continuously pressed downward to make the strip-shaped clamping blocks 202 on the side of the clamping groove 204 engage with the strip-shaped clamping holes 103 formed on the surface of the clamping strip 102. Then, two screws 2062 are manually rotated to thread the screws 2062 with the bolt fixing piece 104. By rotating the screws 2062, the U-shaped elastic block 2061 is in a compressed state. Through the compression of the U-shaped elastic block 2061, the edge pressing strip 101 can be tightly abutted against the tab 201, completing the clamping connection between the front bumper 1 and the fender 2, replacing the traditional connection by a plurality of bolts. This not only improves the tightness of the assembly between the front bumper 1 and the fender 2 but also improves the convenience of the assembly of the front bumper 1 and the fender 2.
