[0065] Furthermore, the shapes of the first support frame 121 and the second support frame 122 can be selectively set as needed, such as triangle, rectangle, trapezoid, etc. The first installation groove 1211 and the second installation groove 1221 are open arc grooves.

[0066] Furthermore, the first support frame 121 and the second support frame 122 may be an integrally formed structure to reduce the installation cost of components and improve assembly efficiency.

[0067] like Figure 5 As shown, the shock-absorbing connecting member 123 includes an inner ring 1231 , a shock-absorbing body 1232 and an outer ring 1233 , and the shock-absorbing body 1232 is embedded between the inner ring 1231 and the outer ring 1233 .

[0068] Furthermore, the shock absorbing body 1232 is made of rubber, the inner ring 1231 and the outer ring 1233 are made of iron, and the shock absorbing connector 123 is formed by casting the inner ring 1231 , the shock absorbing body 1232 and the outer ring 1233 .

[0069] Furthermore, during the casting process, the shock-absorbing body 1232, the inner ring mold and the outer ring mold made of rubber are first processed, the shock-absorbing body 1232 is fixed between the inner ring mold and the outer ring mold, and then the smelted liquid iron is poured into the inner ring mold and the outer ring mold respectively. After cooling, demolding and fine processing are performed to obtain the shock-absorbing connector 123.

[0070] In the embodiment of the present invention, Figure 6 As shown, the suspension connection is connected by bolts, and the bolts are passed through the inner ring 1231 and fixed to the frame 211 at the bottom of the vehicle body 21.

[0071] In the embodiment of the present invention, Figure 7 As shown, the battery compartment 11 includes a plurality of compartments 111 for accommodating standard battery packs 13. The plurality of compartments 111 are respectively surrounded by a battery compartment body 112, a battery compartment cover 113 and a plurality of battery compartment partitions 114 of the battery compartment 11, wherein:

[0072] The plurality of compartment suspension supports 12 are respectively disposed on two opposite outer sides of the battery compartment body 112 , and the battery compartment cover 113 is movably connected to one end of one of the outer sides.

[0073] Furthermore, the number of the bin suspension supports 12 can be selectively set according to actual needs, such as Figure 8 As shown, a battery compartment 11 includes three compartment suspension supports 12. One compartment suspension support 12 is provided on the first outer side surface 1121 of the battery compartment body 112, and two compartment suspension supports 12 are provided on the second outer side surface 1122 opposite to the first side surface 1121, so that the battery compartment 11 is suspended and connected to the bottom of the vehicle body 21 in a direction parallel to the vehicle body 21.

[0074] like Figure 9 As shown, the battery compartment cover 113 is connected to one end of an outer side surface of the battery compartment body 112 through a rotating shaft 14, and one end of the rotating shaft 14 is connected to the battery compartment body 112 through a rolling bearing. The outer ring of the rolling bearing is fixed to the battery compartment body 112, and the inner ring is fixed to the rotating shaft 14, so that the battery compartment cover 113 can rotate relative to the battery compartment body 112 under the drive of the rotating shaft 14; the other end of the rotating shaft 14 is connected to the opening and closing controller 15, and the opening and closing controller 15 controls the rotation of the rotating shaft 14, thereby controlling the opening and closing of the battery compartment cover 113 relative to the battery compartment body 112.

[0075] In the embodiment of the present invention, as shown in FIG10(a), FIG10(b) and Figure 11 As shown, the opening and closing controller 15 includes a control motor 151, a motor push rod 152, an opening and closing locking rod 153, a switch control paddle 154, a brake disc 155, a guide plate 156, a ratchet mechanism 157, a slider 158 and a connecting rod 159. The control motor 151, the motor push rod 152, the slider 158, the connecting rod 159, the opening and closing locking rod 153 and the switch control paddle 154 are connected in sequence. The opening and closing locking rod 153, the switch control paddle 154 and the brake disc 155 are arranged on one side of the guide plate 156, and the ratchet mechanism 157 is arranged on the other side of the guide plate 156. The rotating shaft 14 passes through the center of the brake disc 155 and the center of the ratchet 1571 of the ratchet mechanism 157 and is connected to the battery compartment cover 113 and the battery compartment body 112.

[0076] Furthermore, as shown in FIG10( a ), a first fixing pin 1561 is provided at a position slightly to the left of the bottom center of one side of the guide plate 156. One end of the opening and closing locking lever 153 is movably connected to the first fixing pin 1561, and the other end is movably connected to one end of a connecting rod 159, so that the opening and closing locking lever 153 can rotate about the first fixing pin 1561 under the drive of the connecting rod 159. The other end of the connecting rod 159 is movably connected to a slider 158, which is fixed to the end of the motor push rod 152 away from the control motor 151, so that the slider 158 drives the connecting rod 159 to move under the linear reciprocating drive of the motor push rod 152.

[0077] Furthermore, as shown in Figure 10(a), the rotating shaft 14 is located at the upper 1 / 3 position of the center lines of the two short sides of the guide plate 156, and a second fixing pin 1562 is provided at the lower 1 / 3 position of the center lines of the two short sides on one side of the guide plate 156. One end of the switch control paddle 154 is movably connected to the second fixing pin 1562, and the other end is suspended outside the guide plate 156, or in other words, the other end of the switch control paddle 154 is suspended outside the opening and closing controller 15, as shown in Figure 10(b), so that the switch control paddle 154 can be toggled from the outside of the opening and closing controller 15.

[0078] Furthermore, as shown in FIG10( a ), a sickle-shaped groove is machined on the side of the opening and closing locking rod 153 facing the switch control paddle 154, and an inclined surface matching the shape of the sickle-shaped groove is machined on the end of the switch control paddle 154 facing the opening and closing locking rod 153, so that the switch control paddle 154 and the opening and closing locking rod 153 can be engaged or released.

[0079] In an embodiment of the present invention, when the control motor 151 is energized, the control motor 151 pulls the motor push rod 152 to retreat linearly, and the motor push rod 152 drives the slider 158 to move toward the direction close to the control motor 151. The slider 158 pulls the connecting rod 159 and drives the opening and closing locking rod 153 to rotate counterclockwise. The sickle-shaped groove of the opening and closing locking rod 153 and the inclined surface of the switch control paddle 154 are loosened, so that the battery compartment cover 113 is in an unlocked state relative to the battery compartment body 112.

[0080] When the control motor 151 is powered off, the control motor 151 pushes the motor push rod 152 to extend linearly, and the motor push rod 152 drives the slider 158 to move away from the control motor 151. The slider 158 pushes the connecting rod 159 and drives the opening and closing locking rod 153 to rotate clockwise. The sickle-shaped groove of the opening and closing locking rod 153 and the inclined surface of the switch control paddle 154 are engaged, so that the battery compartment cover 113 is in a locked state relative to the battery compartment body 112. At this time, the switch control paddle 154 cannot be moved from the outside, and the battery compartment cover 113 cannot be opened, which can prevent the loss of the battery pack and ensure the safety of the battery pack and the reliable operation of the electric logistics vehicle.

[0081] Furthermore, a first tooth is processed on the side of the switch control paddle 154 facing the brake disc 155, and a second tooth is processed on the brake disc 155. The first tooth can be clamped or separated from the second tooth, so that the switch control paddle 154 abuts against or separates from the brake disc 155 to control the opening and closing of the switch control paddle 154 in the unlocked state.

[0082] In the embodiment of the present invention, in the unlocked state, Figure 11 As shown, the switch control paddle 154 is separated from the brake disc 155 under the external force in the first direction, and the switch control paddle 154 is in the open state. When the battery compartment cover 113 is tilted by the compartment cover armrest 1131, the rotating shaft 14 drives the ratchet 1571 to rotate. When the pawl 1572 is inserted into the tooth groove position of different ratchet 1571, the battery compartment cover 113 and the battery compartment body 112 are opened at different angles to place the battery pack 13 in or take out the compartment 111.

[0083] In the unlocked state, when the battery compartment cover 113 is closed by the compartment cover armrest 1131 , the switch control paddle 154 abuts against the brake disc 155 under the external force in the second direction, and the switch control paddle 154 is in the closed state.

[0084] Furthermore, the compartment cover armrest 1131 is secured to the battery compartment cover 113 via multiple armrest connecting tubes 1132. The armrest connecting tubes 1132 are hollow, circular tubes. The diameter, length, type, and arrangement of the armrest connecting tubes 1132 on the surface of the battery compartment cover 113 can be selectively configured based on actual needs, as long as the compartment cover armrest 1131 can be suspended from the surface of the battery compartment cover 113 for easy gripping. For example, the armrest connecting tubes 1132 can be straight or curved. Multiple straight tubes are secured to the surface of the battery compartment cover 113, with their ends fixedly connected to the compartment cover armrest 1131 via curved tubes to strengthen the connection between the compartment cover armrest 1131 and the battery compartment cover 113. The compartment cover armrest 1131 is a hollow, circular tube with an inner diameter larger than the armrest connecting tubes 1132 to which it is fixedly connected.

[0085] In the embodiment of the present invention, Figure 12 As shown, a compartment slide rail is provided in the compartment 111 , and the battery pack 13 can slide along the compartment slide rail so that the battery pack 13 can be placed in or taken out of the compartment 111 .

[0086] like Figure 12 As shown, the compartment slide rail 1111 includes a first self-locking slide rail 1111, a second self-locking slide rail (not shown in the figure) and a battery pack accommodating slot 1112. The self-locking slide rail can self-lock in the retracted and extended states. After self-locking, the slide rail cannot be pulled, thereby ensuring the stability and safety of the battery pack in and out.

[0087] The first self-locking slide rail 1111 and the second self-locking slide rail are symmetrically arranged on the two opposite inner side surfaces of the compartment 111. The battery pack accommodating groove 1112 is fixedly connected to the two opposite side surfaces of the first self-locking slide rail 1111 and the second self-locking slide rail with a accommodating groove slide rod 11121 respectively. The accommodating groove slide rod 11121 slides in the first self-locking slide rail 1111 and the second self-locking slide rail to drive the battery pack 13 accommodated in the battery pack accommodating groove 1112 to be placed in or taken out of the compartment 111.

[0088] Furthermore, a first self-locking slide rail 1111 is disposed on the inner side of the battery compartment partition 114 of the compartment 111, and a second self-locking slide rail is disposed on the inner side of the compartment 111 opposite the inner side of the battery compartment partition 114. The lengths of the first self-locking slide rail 1111, the second self-locking slide rail, and the receiving slot slide bar 1112 can be selectively adjusted based on actual needs.

[0089] Furthermore, the first self-locking slide rail 1111 is disposed on one end of the battery compartment partition 114 near the battery compartment cover 113, and the second self-locking slide rail is disposed symmetrically to the first self-locking slide rail 1111. The self-locking slide rail has a load capacity of up to 62 kg, which fully meets the weight requirement of the battery pack.

[0090] Or, as Figure 13As shown, the compartment slide rail includes a first nylon slide rail 1113, a second nylon slide rail 1114, a third nylon slide rail 1115 and a fourth nylon slide rail 1116 located at the four corners of the compartment 111. The four corners of the battery pack 13 slide along the first nylon slide rail 1113, the second nylon slide rail 1114, the third nylon slide rail 1115 and the fourth nylon slide rail 1116 respectively to place in or take out the compartment 111.

[0091] Furthermore, the first nylon slide rail 1113 is arranged at the first corner of the four corners of the compartment 111, including a first slide rail guide seat 11131 fixed at one end of the first corner and a second slide rail guide seat 11132 fixed at the other end of the first corner. The first slide rail guide seat 11131 and the second slide rail guide seat 11132 are in the shape of a "∟" right angle that fits the first corner. The seat width of the first slide rail guide seat 111141 and the second slide rail guide seat 11132 along the first corner can be selectively set according to actual needs. Similarly, the second nylon slide rail 1114, the third nylon slide rail 1115, and the fourth nylon slide rail 1116 are the same as the first nylon slide rail 1113, and will not be repeated here. In addition, the nylon slide rail is a polymer material with a smooth surface and strong hardness, which ensures a smooth transition of collision and friction between the battery pack and the slide rail. It will not cause damage to the battery pack due to excessive hardness, nor will it cause the slide rail itself to be squeezed and deformed due to the material being too soft. It ensures the accurate positioning of the battery pack while ensuring the integrity of the battery pack.

[0092] Furthermore, if Figure 14 As shown, a pre-compression member 1134 is provided at the top cover position 1133 of the battery compartment cover 113 corresponding to the center of each compartment 111, which is used to apply pressure to the battery pack handle 131 on the top of the battery pack 13 to fix the battery pack 13 when the battery compartment cover 113 is closed. In this way, the battery pack is safely fixed under the dual effects of the positioning of the nylon guide rail and the compression of the pre-compression member.

[0093] Furthermore, one or more battery pack handles 131 may be provided on other outer sides of the battery pack 13 to facilitate actual use.
