[0018] In order to make the technical purpose, technical solution and beneficial effects of the present utility model clearer, the technical solution of the present utility model will be further described below in conjunction with the attached drawings and specific embodiments.

[0019] A tractor battery layout structure provided by the present utility model, as shown in the figure, includes a front bracket 1. Spaces for accommodating batteries are provided on both the upper side and the lower side of the front bracket 1. An upper fixing structure for fixing the upper battery 2 (defining the battery arranged on the upper side of the front bracket 1 as the upper battery 2) is provided on the upper side of the front bracket 1, and a lower fixing structure for fixing the lower battery 8 (defining the battery arranged on the lower side of the front bracket 1 as the lower battery 8) is provided on the lower side of the front bracket 1. A protective cover 3 for sleeving outside the lower battery 8 is sleeved outside the lower fixing structure, and the protective cover 3 is connected to the front bracket 1.

[0020] The upper fixing structure includes at least one set of upper fixing groups. Each upper fixing group includes a pressure plate 4 arranged on the upper surface of the upper battery 2 and two first screws 5. The two ends of the pressure plate 4 extend to the outside of the upper battery 2. A nut is provided at the tail end of the first screw 5. Openings are formed at both ends of the pressure plate 4 through which the tip of the first screw 5 can pass but the tail end of the first screw 5 is blocked (that is, the diameter of the opening is larger than the diameter of the first screw 5 and smaller than the diameter of the nut of the first screw 5). The first screw 5 is vertically arranged with respect to the upper surface of the front bracket 1, and screw holes or light holes are formed at positions corresponding to the first screw 5 on the front bracket 1, so that the first screw 5 is threadedly connected to the screw holes, or the first screw 5 passes through the light holes and is screwed to a nut to be fixed on the front bracket 1.

[0021] The usage method of the upper fixing structure is as follows:

[0022] The upper battery 2 is placed in the placement space of the front bracket 1. The pressure plate 4 is placed on the upper surface of the upper battery 2, ensuring that both ends of the pressure plate 4 extend out of both sides of the battery. The first screw 5 is passed through the opening on the pressure plate 4. If there are screw holes on the front bracket 1, the first screw 5 is directly screwed into the screw holes. If there are light holes, after the first screw 5 passes through the light holes, a nut needs to be screwed onto the front end of the screw, and the relative position of the first screw 5 and the front bracket 1 is adjusted so that the pressure plate 4 applies pressure to the battery to ensure that the battery will not loosen or shift.

[0023] When the upper fixing structure is set to at least two groups of upper fixing groups, the at least two groups of upper fixing groups are arranged at intervals along the upper side battery 2.

[0024] The lower fixing structure includes at least one group of lower fixing groups. The lower fixing group includes a U-shaped support member 6 sleeved on the outer surface of the lower side battery 8 and two second screw rods 7. The two second screw rods 7 are respectively arranged on both sides of the U-shaped support member 6 (that is, on both sides of the battery), and are arranged in cooperation with the U-shaped support member 6. Define both sides of the U-shaped support member 6 as two parts respectively arranged on the left and right side walls of the battery. A connecting plate is respectively connected to both sides of the U-shaped support member 6. A hole passage with an axis perpendicular to the front bracket 1 is opened on the connecting plate. A nut is arranged at the tail end of the second screw rod 7. The diameter of the hole passage is larger than the diameter of the second screw rod 7 and smaller than the diameter of the nut of the second screw rod 7), so that the second screw rod 7 is vertically arranged with respect to the upper surface of the front bracket 1. The second screw rod 7 passes through the hole passage on the connecting plate and the nut of the second screw rod 7 abuts against the connecting plate. A threaded hole or a smooth hole is opened at the position corresponding to the second screw rod 7 on the front bracket 1, so that the second screw rod 7 is threadedly connected to the threaded hole, or the second screw rod 7 passes through the smooth hole and is screwed to the nut to be fixed on the front bracket 1. The second screw rod 7 can rotate relative to the U-shaped support member 6. The U-shaped support member 6 can abut against the lower side of the outer surface of the lower side battery 8 and make the upper side of the outer surface of the lower side battery 8 abut against the front bracket 1.

[0025] The usage method of the lower fixing structure is as follows:

[0026] The lower side battery 8 is placed in the U-shaped support member 6. The second screw rod 7 passes through the connecting plate, and the nut of the second screw rod 7 abuts against the connecting plate. If a threaded hole corresponds to the position of the second screw rod 7 on the front bracket 1, the second screw rod 7 is directly screwed into the threaded hole. If it is a smooth hole, after the second screw rod 7 passes through the smooth hole, a nut needs to be screwed on the front end of the screw rod to adjust the relative position of the second screw rod 7 and the front bracket 1, so that the U-shaped support member 6 and the front bracket 1 cooperate to apply pressure to the lower side battery 8 to ensure that the battery will not loosen or shift.

[0027] When the lower fixing structure is set to at least two groups of lower fixing groups, the at least two groups of lower fixing groups are arranged at intervals along the lower side battery 8.

[0028] In order to prevent excessive local pressure on the lower surface of the lower side battery 8 from deforming, the lower fixing structure further includes a support plate 9 abutted against the lower surface of the lower side battery 8. The support plate 9 is located between the U-shaped support member 6 and the lower side battery 8. The four sides of the support plate 9 extend upward and respectively adhere to the four sides of the lower side battery 8. The protective cover 3 covers the outside of the lower fixing structure and the lower side battery 8.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Any equivalent replacement of the present invention and modifications or partial replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
